If the storage space is enlarged, an external memory is designed for the single chip microcomputer or the single chip microcomputer with larger storage space is used, but the cost of the rack-mounted communication equipment is undoubtedly increased.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

As shown in fig. 1, fig. 1 is a schematic view of a distribution situation of each board card in a rack-mounted communication device, where the communication device includes a main control card and a plurality of service cards, the plurality of service cards are connected with the main control card respectively, and each service card includes a single chip, which can be used for management of own board card information and operation parameters, such as obtaining information of identity, temperature, and the like of the own board card and reporting the information to the main control card. In order to save cost, the operating program of the single chip microcomputer in the service card is usually stored in the built-in memory, and the storage area of the single chip microcomputer is usually divided into a starting area, an operating area and a loading area in consideration of reliability. The starting area is used for storing codes related to starting of the single chip microcomputer, updating is usually not performed, the operation area is used for storing a currently operated program and cannot be covered during operation, and the loading area is used for temporarily storing a program to be upgraded during program upgrading.

And when the single chip microcomputer is started, executing the program in the starting area, and if the program to be upgraded in the loading area is detected, loading the program to be upgraded into the operation area for operation. Under a common condition, in order to facilitate version management, when the same type of single chip microcomputer is deployed on different service cards, if the functions of the different service cards are different, the single chip microcomputer still can be packaged into an operation image file to be stored in the single chip microcomputer. If the service card needs to expand more functions, the storage space occupied by the same running image file is increased, but based on cost consideration, the storage space of a memory built in the single chip microcomputer is basically not large, so that the software function expansion of the service card is limited. Moreover, if the single chip microcomputer is designed to expand a memory or is replaced by the single chip microcomputer with larger memory space, the equipment cost is increased undoubtedly.

The above prior art solutions have shortcomings which are the results of practical and careful study of the inventor, and therefore, the discovery process of the above problems and the solutions proposed by the following embodiments of the present invention to the above problems should be the contribution of the inventor to the present invention in the course of the present invention.

In order to solve the above technical problems, an embodiment of the present application provides a method for upgrading a chip program, in which a program to be upgraded is stored in a loading area of a main control card instead of a loading area of a single chip microcomputer, so that it is not necessary to add a storage medium to a service card and increase a storage space of the single chip microcomputer, and equipment cost can be saved. Therefore, the method can give consideration to both the equipment cost and the function expansion of the service card.

Referring to fig. 2, fig. 2 is a flowchart of a method for upgrading a chip program according to an embodiment of the present application, where the method is applied to a service card, and includes the following steps:

step S110: and when the program of the single chip microcomputer is determined to be required to be upgraded, acquiring the program to be upgraded from the loading area of the main control card.

It can be understood that the chip program upgrading method provided by the present application is executed by a single chip in a service card, and for convenience of description, the following embodiments all describe with the service card as an execution subject.

In the embodiment of the application, the main control card divides a storage space of a storage medium of the main control card as a loading area for storing a program to be upgraded for upgrading the program of the single chip microcomputer, wherein the program to be upgraded can be input into the main control card by an administrator or downloaded from a network by the main control card. Therefore, when the service card determines that the program of the single chip microcomputer needs to be upgraded, the service card can acquire the program to be upgraded from the loading area of the main control card.

In some embodiments, after the service card is powered on and started, the service card may first determine whether the program of the single chip microcomputer needs to be upgraded, and when the service card determines that the program of the single chip microcomputer needs to be upgraded, the service card may send an upgrade request to the main control card, and after receiving the upgrade request, the main control card reads the program to be upgraded from the loading area of the main control card according to the upgrade request, and then sends the program to be upgraded to the service card. Therefore, the problem that the main control card directly sends the program to be upgraded to the service card, and the singlechip is not provided with a loading area for storing the program to be upgraded, so that the program currently running in the running area is directly covered by the program to be upgraded (the program in the running area cannot be covered during running) and the singlechip runs abnormally can be avoided.

The program to be upgraded can be understood as a related program for implementing the control and operation maintenance functions of the single chip microcomputer, such as configuration of forwarding logic of the service card, temperature alarm configuration, state reporting configuration, and the like. Namely, the programs for upgrading the running programs of the single chip microcomputer according to the functions of the service card, and the programs can be called as programs to be upgraded.

Step S120: and loading the program to be upgraded into the operation area of the single chip microcomputer to operate so as to upgrade the program of the single chip microcomputer.

The single chip microcomputer is not required to be provided with a loading area, and only the starting area and the operation area are required to be arranged, so that when the service card is started in a power-on mode, the program in the starting area is operated firstly, if the program of the single chip microcomputer is detected to be required to be upgraded, if the program is required to be upgraded, the program to be upgraded is obtained from the main control card, and after the program to be upgraded is obtained by the single chip microcomputer, the program to be upgraded can be directly loaded into the operation area to operate, so that the program of the single chip microcomputer is upgraded, and the operation program in the single chip microcomputer is upgraded. The operation area is used for storing the current operation program, so that the upgrading of the operation program of the singlechip can be completed after the program to be upgraded is operated in the operation area.

The loading of the program to be upgraded into the running area may be understood as covering the program to be upgraded into the running area, or storing the program to be upgraded into the running area, and may be flexibly set according to the requirements of the user.

In the implementation process, the program to be upgraded is stored in the loading area of the main control card instead of the loading area of the single chip microcomputer, so that the equipment cost can be saved without adding a storage medium for the service card and increasing the storage space of the single chip microcomputer, and more storage spaces can be provided for the operation area of the single chip microcomputer because the single chip microcomputer is not provided with the loading area, so that the operation mirror image files with more functions expanded by the service card can be stored in the operation area for operation, and the function expansion of the service card is facilitated. Therefore, the method can give consideration to both the equipment cost and the function expansion of the service card.

On the basis of the embodiment, the main control card is divided into the loading area in advance, and the loading area is used for storing the program to be upgraded. After obtaining the program to be upgraded, the main control card may perform preliminary verification on the program to be upgraded to check the validity thereof, for example, a check core of the program to be upgraded is generated in advance, and after obtaining the program to be upgraded, the program to be upgraded is verified by using the check core; or the master control card obtains the ID of each service card in the program to be upgraded, and after obtaining the ID of each service card in the program to be upgraded, the master control card determines whether each service card is the same as the service card connected to the master control card, if not, the master control card determines that the program to be upgraded is not the upgrading program of the service card connected to the master control card, and if not, the verification is not passed, otherwise, the verification is passed. And after the program to be upgraded is determined to be legal, storing the program to be upgraded in a loading area of the main control card.

Or, after the service card obtains the program to be upgraded, the service card may also check the program to be upgraded first, and the checking process is similar to that of the main control card, which is not repeated herein.

When the master control card detects that the program to be upgraded in the loading area of the master control card is updated (if the currently acquired program to be upgraded is compared with the program to be upgraded which is stored in the loading area historically, if the currently acquired program to be upgraded is different from the program to be upgraded, the program to be upgraded is determined to be updated), the master control card can send indication information to the service card so as to indicate that the program of the single chip microcomputer of the service card can be upgraded, and the service card can determine that the program of the single chip microcomputer of the service card needs to be upgraded after receiving the indication information.

It can be understood that, if the main control card is connected with a plurality of service cards, the main control card sends the indication information to each service card, so that when the program of the single chip microcomputer is upgraded, the programs of the single chip microcomputers in the plurality of service cards can be upgraded in batch, the upgrading efficiency is higher, the upgrading process of the program of the single chip microcomputer in each service card is the same, and the upgrading of the program of the single chip microcomputer in one service card is taken as an example in the embodiment of the present application for explanation. Or, the main control card may also send the indication information to the service card that needs to be upgraded according to the user's requirement, for example, the user may send an instruction to the main control card, where the instruction carries the ID of the service card, and the main control card may send the indication information to the corresponding service card according to the ID of the service card, so as to indicate that the program of the single chip microcomputer of the service needs to be upgraded.

In other embodiments, in order to facilitate the service card to determine whether the program of the single chip microcomputer needs to be upgraded, the main control card may further generate an upgrade flag after obtaining the program to be upgraded, that is, when the main control card determines that the program of the single chip microcomputer in the service card needs to be upgraded (if the currently obtained program to be upgraded is not consistent with the pre-stored program to be upgraded, it is determined that the program of the single chip microcomputer needs to be upgraded), and then generate an upgrade flag. The main control card sends the upgrade mark to the service card, and the service card can determine whether the program of the single chip microcomputer needs to be upgraded according to the upgrade mark.

The service card can be marked with a corresponding loading mark in advance, the loading mark is used for representing whether the program of the single chip microcomputer needs to be upgraded or not, after the service card receives the upgrading mark sent by the main control card, the upgrading mark can be compared with the loading mark recorded by the service card, if the upgrading mark is different from the loading mark, the loading mark is updated according to the upgrading mark, and if the loading mark is updated to the upgrading mark, or the loading mark is updated to other marks, the service card can sense the change of the loading mark. Therefore, when the service card detects that the loading mark representation of the single chip microcomputer needs to be upgraded, the service card determines that the program of the single chip microcomputer needs to be upgraded.

For example, when the system is initially powered on, the single chip microcomputer may automatically generate an initial loading mark (e.g., 00), or the main control card issues the generated initial loading mark to the service card, the main control card generates an upgrade mark (e.g., 01) after obtaining a program to be upgraded and sends the upgrade mark to the service card, the service card updates the initial loading mark to the upgrade mark, the loading mark recorded in the service card becomes 01 at this time, and if the service card detects that the loading mark is 01 (indicating that the loading mark represents that the upgrading is required), it is determined that the program of the single chip microcomputer needs to be upgraded. After the program of the single chip microcomputer is upgraded, the service card can update the loading mark to the initial loading mark again, if the loading mark is updated to 00, then the service card detects whether the loading mark changes when being started next time, and if the loading mark changes, the program of the single chip microcomputer is determined to need to be upgraded.

In the implementation process, the program to be upgraded is stored in the loading area in the main control card, so that whether the program of the single chip microcomputer needs to be upgraded can be sensed in real time through the main control card, and the processing resource of the single chip microcomputer does not need to be occupied.

On the basis of the above embodiment, in order to ensure the reliability of program upgrade of the single chip microcomputer, the main control card may further be provided with a main loading area and a standby loading area, as shown in fig. 3, both the main loading area and the standby loading area may be used for storing a program to be upgraded, and a user may place the program to be upgraded in the main loading area and/or the standby loading area according to a requirement.

When the master control card issues the upgrade flag to the service card, the upgrade flag may be issued according to the loading area where the program to be upgraded is located, for example, if the program to be upgraded in the master loading area is upgraded, the generated upgrade flag may be represented as 01, and if the program to be upgraded in the backup recording area is upgraded, the generated upgrade flag may be represented as 02, that is, the upgrade flag generated in this case may also represent the identifier of the loading area in the master control card.

After the service card obtains the upgrade flag, the loading flag is updated to the upgrade flag, so that the loading flag in the service card can be used to represent the flag of the loading area in the main control card. Therefore, when the service card determines that the program of the single chip microcomputer needs to be upgraded, the service card can send an upgrade request carrying a corresponding loading mark to the main control card, after the main control card obtains the upgrade request, the main control card obtains the loading mark from the upgrade request, and then the service card can read the program to be upgraded from the corresponding loading area according to the loading mark and send the program to the service card.

For example, if the load flag is a load flag (e.g. 01) of the main load area, the main control card obtains the program to be upgraded from the main load area, and if the load flag is a load flag (02) of the standby load area, the main control card reads the program to be upgraded from the standby load area.

In the implementation process, the main control card is provided with a main loading area and a standby loading area, so that the business card acquires the corresponding program to be upgraded from the loading area corresponding to the main control card by sending an upgrading request to the main control card, and the upgrading reliability of the single chip microcomputer can be ensured.

In other embodiments, in order to ensure that the single chip microcomputer can operate, the main loading area of the main control card may be configured to be dedicated for storing the current program to be upgraded, and the standby loading area is configured to store the program to be upgraded which is updated last time, that is, the historical program to be upgraded. Therefore, the historical program to be upgraded can be acquired from the standby loading area to operate, so that the single chip microcomputer can operate the program to be upgraded in the standby loading area, and the normal operation of the single chip microcomputer can be ensured. If the single chip microcomputer is upgraded successfully from the program to be upgraded in the main loading area, the current program to be upgraded in the main loading area can be stored in the standby loading area, and the historical program to be upgraded in the standby loading area is deleted, so that the subsequent program to be upgraded can be stored in the main loading area during subsequent upgrading, and the single chip microcomputer can preferentially acquire the program to be upgraded in the main loading area for upgrading.

On the basis of the above embodiment, in order to ensure the upgrade reliability, the service card may also start the timer when sending an upgrade request to the main control card, and if it is determined that the program upgrade of the single chip microcomputer fails after a preset time period, acquire the program to be upgraded from another loading area of the main control card to upgrade.

For example, the upgrade request sent by the service card to the main control card carries a loading flag (e.g. 01) of the main loading area of the main control card, the main control card reads the program to be upgraded from the main loading area and sends the program to the service card, and after the timer reaches a preset time, if the single chip has not received the program to be upgraded sent by the main control card, or if the single chip fails to operate the program to be upgraded, the upgrade failure is indicated. At this time, the service card may send a upgrade request to the main control card, and the load tag carried in the upgrade request is the load tag (e.g. 02) of the standby load area of the main control card, and then the main control card reads the program to be upgraded from the standby load area and sends the program to the service card.

If the service card finishes receiving the program to be upgraded before the preset time length is reached, or the singlechip successfully runs the program to be upgraded, the upgrading is successful, at the moment, the service card can renew the current loading mark (01) of the singlechip into the initial loading mark (such as 00) and delete the timer. When the upgrade fails, the current loading mark can be automatically updated to the loading mark (such as 02) of the standby loading area of the main control card, meanwhile, the program to be upgraded received before is cleared, and then an upgrade request is sent to the main control card; or, before sending the upgrade request to the main control card, the service card may feed back prompt information indicating that the upgrade fails to the main control card, after receiving the prompt information, the main control card may generate a upgrade flag (e.g., 02) based on the program to be upgraded in the standby loading area, send the upgrade flag to the service card, then the service card updates the current loading flag (01) to the upgrade flag (02), and send the upgrade request to the main control card, where the upgrade request carries the load flag (02) in the standby loading area.

In some embodiments, the main control card may further include a plurality of loading areas, not only the main and standby loading areas, where the plurality of loading areas may be used to store the programs to be upgraded respectively, or store the programs to be upgraded at different times, so as to ensure that when the single chip microcomputer fails to obtain the programs to be upgraded from one loading area during the upgrade process, the programs to be upgraded may also be obtained from other plurality of standby loading areas for upgrade, thereby ensuring the upgrade reliability of the single chip microcomputer.

Referring to fig. 4, fig. 4 is a flowchart of another chip program upgrading method provided in this embodiment of the present application, where the method is applied to a main control card in a communication device, and the method includes the following steps:

step S210: and receiving an upgrading request sent by the service card.

The upgrade request may be sent by the service card when the program of the single chip microcomputer needs to be upgraded.

Step S220: and reading a program to be upgraded from a loading area of the main control card according to the upgrading request.

The loading area on the main control card is used for storing a program to be upgraded for upgrading the single chip microcomputer, and after receiving an upgrading request sent by the service card, the main control card reads the program to be upgraded from the loading area and sends the program to be upgraded to the service card, so that the service card can directly run the program to be upgraded to upgrade the program of the single chip microcomputer.

Step S230: and sending the program to be upgraded to the service card so that the service card loads the program to be upgraded to an operation area of a single chip microcomputer of the service card for operation, so as to upgrade the program of the single chip microcomputer, wherein the operation area is used for storing the current operation program.

In some embodiments, the main control card includes a main loading area and a standby loading area, and the upgrade request carries a corresponding loading tag representing the loading area, so that after receiving the upgrade request, the main control card obtains a loading tag from the upgrade request, reads the program to be upgraded from the main loading area and sends the program to be upgraded to the service card if the loading tag is the loading tag of the main loading area, and reads the program to be upgraded from the standby loading area and sends the program to the service card if the loading tag is the loading tag of the standby loading area.
