Background

An important component of a rail transit control system is a Remote Input and Output Module (RIOM), which includes an RIOM overall controller and a plurality of Input/Output (IO) monitoring independent controllers. The traditional RIOM host and the IO board card are connected through a CAN bus, and data monitored by the IO board card are transmitted through the CAN bus. Since the general transmission rate supported by the CAN bus is only 500Kbps and the available bytes are less than 50%, the CAN bus is suitable for transmitting IO status or limited analog data and PWM data. However, the IO board often needs to support the remote programming function, and for a program of 800KB-1MB, a single board needs more than 20s to complete the program transmission process. The IO board card in the RIOM system has a plurality of board cards, and if systematic upgrading is to be completed, longer time needs to be consumed, so that the upgrading efficiency is greatly influenced.

With the increase of processing power of embedded processors, many application scenarios that require high-performance processors have been replaced for embedded processors before. Software upgrade often does not need to be concerned with when using high performance processors, platform resources are sufficient to use operating systems and file systems, and network upgrades can be performed using mature OTA policies. After the embedded processor is replaced, although the processing performance can meet the requirement, due to the limitation of RAM and Flash resources, a file system and an operating system are not adopted. The upgrading of the IO board software CAN only adopt a field bus, such as a 485 or CAN bus. Due to the bandwidth of the bus, the number of nodes mounted on the bus is not too large.

At present, the software upgrading efficiency in the RIOM system does not draw wide attention, the existing method only adopts a serial port or a CAN bus as a transmission path and adopts a strategy of upgrading one by one, namely, the programs of a plurality of board cards are programmed and sequentially executed, so that the software upgrading time is gradually increased along with the gradual increase of network nodes, and the method is extremely not beneficial to the rapid deployment of software.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic flowchart of a software deployment method of a rail transit remote input/output module provided by the present invention, and as shown in fig. 1, the method includes:

s1, dividing board cards to be deployed with the same function in the remote input/output module RIOM of the rail transit into the same home domain to determine the home domain to which all the board cards to be deployed in the RIOM belong;

and S2, deploying the target software of the same home domain to the corresponding home domain based on the CANFD communication mode and the redundant network, so as to perform software deployment on all boards to be deployed.

It should be noted that the execution subject of the method may be a computer device.

Optionally, the software deployment method for the rail transit remote input/output module provided by the invention can perform software deployment (software upgrade) on each board card in the rail transit remote input/output module shown in fig. 2.

As shown in fig. 2, the RIOM includes three roles, which are respectively a program manager at the cloud, a remote IO manager (e.g., the RIOM host in fig. 2), and a plurality of local IO controllers (e.g., all boards to be deployed in fig. 2). The program manager is a deployed cloud server and is used for storing and distributing the software program version of the local IO controller. The remote IO manager has a heterogeneous network, can establish a communication relationship with the cloud server and a field CANFD bus at the same time, is responsible for requesting a target software program from the cloud server, and issues the board cards to be deployed in the same home domain through the CANFD bus and a redundant network deployed in the RIOM network to complete software deployment of the board cards to be deployed in the same home domain. The concrete implementation is as follows:

in an actual scenario, although the number of nodes in the entire RIOM network (each board to be deployed corresponds to one node in the RIOM network) is large, the number of types of boards to be deployed is relatively limited. The method comprises the steps that software running in all boards with the same function in an RIOM is consistent, on the basis of a CANFD communication strategy of domain division, CANFD communication only applicable to a broadcasting mode is changed into a selective communication mode with domain identification, all boards to be deployed in the RIOM are subjected to domain division according to the corresponding functions of the boards, the boards to be deployed with the same function are divided into the same home domain, on the basis of the domain division, all boards to be deployed in the whole RIOM are subjected to domain division, and the home domain to which each board to be deployed in the whole RIOM belongs is obtained.

For example, after all boards to be deployed in the entire RIOM are powered on, by modifying the functional domain field of the ID of each powered-on board to be deployed, for example, the functional domain fields of the IDs of boards to be deployed with the same function may be represented by a uniform home domain number. Based on the above, the home domain to which each board card to be deployed belongs is obtained.

Based on the CANFD communication mode, performing domain identification on all boards to be deployed (for example, the number of a home domain of each board to be deployed can be determined), deploying target software of the same home domain into the corresponding home domain at the same time, implementing collaborative deployment of the same home domain, and finally completing software deployment of all boards to be deployed. The CANFD communication method is based on CANFD bus.

The CANFD network is based on a CAN network, which inherits the main characteristics of the CAN bus. The CAN FD bus compensates the restriction of CAN bus bandwidth and data field length, and increases the bus bandwidth to 5Mbps and the data field length to 64 Byte. For the remote programming function, the CAN FD bus is more suitable than the CAN bus, and the communication efficiency CAN be improved by about 10 times. Likewise, high bandwidth can better support the data transfer requirements of a variety of applications. The original CAN bus is replaced by a CAN FD bus architecture, and the efficiency of data transmission CAN be improved on the basis of hardware by utilizing CAN FD high bandwidth and an increased data field.

The software deployment method of the rail transit remote input and output module provided by the invention CAN replace the traditional CAN communication or serial communication by using the CANFD communication mode and the redundant network based on the attribution domain to which the divided board cards to be deployed belong, and simultaneously realize the software deployment of the board cards to be deployed in the same attribution domain, thereby improving the software deployment efficiency.

Further, in an embodiment, in step S2, deploying the target software of the same home domain to the corresponding home domain based on the CANFD communication method and the redundant network may specifically include:

s21, performing CRC (cyclic redundancy check) on target software received by each board card to be deployed in the same home domain respectively to determine a first board card to be deployed and a second board card to be deployed in the same home domain;

s22, deploying target software of the same home domain to a first board card to be deployed based on a CANFD communication mode;

s23, deploying the target software of the same home domain to a second board card to be deployed based on a redundant network;

the first board card to be deployed is a board card to be deployed corresponding to target software which passes CRC in the same home domain;

and the second board card to be deployed is a board card to be deployed corresponding to the target software which does not pass the CRC in the same home domain.

Optionally, after receiving target software transmitted based on a CANFD bus and a redundant network, board cards to be deployed in the same home domain need to check the integrity of the received target software, wherein the software deployment method of the rail transit remote input/output module provided by the invention adopts a cyclic redundancy check CRC check mode to check the integrity of the target software transmitted in a byte form. Then, according to the CRC check result, classifying the boards to be deployed in the same home domain, specifically:

dividing the board card to be deployed corresponding to the target software passing the CRC check into a first board card to be deployed, which indicates that the first board card to be deployed receives correct target software, and at this time; and dividing the board card to be deployed corresponding to the target software which does not pass the CRC check into a second board card to be deployed, which indicates that the second board card to be deployed does not receive correct target software. And then deploying the target software of the same home domain to the first board to be deployed and the second board to be deployed based on the CANFD communication mode and the redundant network.

According to the software deployment method of the rail transit remote input and output module, before software deployment is carried out on the board cards to be deployed, the completeness of target software to be deployed is verified so as to ensure the correctness and the completeness of the software deployment, meanwhile, the board cards to be deployed in the same attribution domain are subjected to software deployment by taking the 'domain' as a unit, the software deployment time can be decoupled from the number of nodes of the 'domain', and the network utilization rate is fully improved.

Further, in an embodiment, the step S23 may specifically include:

s231, disconnecting the second board card to be deployed from the RIOM, and resending the target software of the same home domain to the second board card to be deployed through the redundant network until the target software received by the second board card to be deployed passes CRC check, and deploying the target software of the same home domain to the second board card to be deployed based on the redundant network.

Optionally, the boards to be deployed in the same home domain are divided into a first board to be deployed that receives correct target software and a second board to be deployed that does not receive correct target software by using the above method, the first board to be deployed may implement simultaneous deployment of the target software based on the CANFD communication manner, and the second board to be deployed does not receive correct target software, so that the second board to be deployed needs to resend the upgrade requirement, in order to not affect software deployment of the first board to be deployed in the domain upgrade process, a node corresponding to the second board to be deployed needs to be disconnected from the entire RIOM network, so as to avoid affecting software deployment processes of nodes corresponding to other first boards to be deployed, and simultaneously, the redundant network shown in fig. 2 is used to receive the target software, and after the target program is received, the integrity of the program installation package corresponding to the target software is checked again by using the CRC check manner, the integrity of the program is guaranteed. And deploying the target software of the same home domain to the second board card to be deployed to receive the correct target software based on the redundant network at the same time until the second board card to be deployed passes the CRC check, namely after the second board card to be deployed receives the correct target software.

The software deployment method of the rail transit remote input and output module provided by the invention adopts a redundancy mechanism to solve the problem of software packet loss caused by domain upgrading, and simultaneously ensures the consistency, the correctness and the safety of software deployment in the same home domain.

Further, in an embodiment, all boards to be deployed may specifically include one or more of the following functional boards:

the data acquisition system comprises a data input DI acquisition board card, a data output DO acquisition board card and an analog input AI acquisition board card.

Optionally, the whole board to be deployed may specifically include one or more functional boards among a data input DI acquisition board, a data output DO acquisition board, and an analog input AI acquisition board. When the board card to be deployed which is powered on in the RIOM network at a certain moment comprises any one of the three functional board cards, all the board cards to be deployed in the RIOM network are divided into the same home domain, and when the board cards to be deployed which are powered on in the RIOM network at a certain moment comprise a plurality of the three functional board cards, all the board cards to be deployed in the RIOM network are divided into a plurality of home domains, and the software of the board cards to be deployed in the whole home domain is deployed at the same time by adopting the method.

The software deployment method of the rail transit remote input and output module provided by the invention can realize the cooperative deployment of different function board card software in the RIOM network, and improve the software upgrading efficiency. Further, in an embodiment, after it is determined that all boards to be deployed include multiple functional boards, multiple home domains to which all boards to be deployed belong are determined, and target software of each home domain is respectively determined:

determining target software of a home domain to which the DI acquisition board card belongs as a first software program;

determining target software of a home domain to which the DO acquisition board card belongs as a second software program;

and determining the target software of the attribution domain of the AI acquisition board card as a third software program.

Optionally, if it is determined that all the function boards to be deployed powered on in the entire RIOM network include the above three kinds of function boards, the function boards are subjected to home domain division according to the functions of the function boards to be deployed, DI acquisition boards with the same function are divided into the same home domain, DO acquisition boards with the same function are divided into the same home domain, and AI acquisition boards with the same function are divided into the same home domain.

As described above, after determining that all boards to be deployed belong to different home domains, respectively determining the target software of each home domain, specifically: determining target software of a home domain to which the DI acquisition board card belongs as a first software program; determining target software of a home domain to which the DO acquisition board card belongs as a second software program; and determining the target software of the attribution domain of the AI acquisition board card as a third software program. Then, by using the software deployment method, the first software program may be deployed to the home domain to which the DI acquisition board belongs, the second software program may be deployed to the home domain to which the DO acquisition board belongs, and the third software program may be deployed to the home domain to which the AI acquisition board belongs.
