The belt fault point list comprises corresponding relations among fault point positions, fault point types and fault point codes.

In production, in order to ensure safe operation of the belt, a plurality of groups of protection detection devices are arranged, such as a belt tearing detection device, a pull rope detection device (16 groups), a deviation detection device and a slip detection device, and when the belt tearing, the pull rope fault, the belt deviation and the belt slip are detected, detection point signals corresponding to the detection devices flash; in addition, the belt runs and is interlocked with a charging bucket at the top of the blast furnace, namely when a material stub bar on the belt reaches a stub bar OK detection point, the charging condition of a receiving tank of the blast furnace is required to be met, namely, the conditions that the receiving tank is empty, an upper sealing valve is opened in place, a material flow valve is closed in place, an upper chute swings to the receiving tank position, a lower sealing valve is closed in place, the discharging pressure of the charging bucket is OK, a discharging pressure valve is opened in place, and a pressure equalizing valve is closed in place are met simultaneously, wherein if any condition is not met, a interlocking point signal can be flickered. In step S10, the fault point signal may be a detection point signal or a linkage point signal, but may also be other signals, which are not listed here. As to how to receive the fault point signal, the fault point signal may be received by the SR flip-flop, or may be received by another flip-flop or another device, and the manner of receiving the fault point signal is not particularly limited. The number of the fault point signals is not particularly limited.

In step S11, the target failure point code is a code of a failure point at which a failure point signal is received, for example, a rope failure point, a motor failure point, a band-type brake failure point, or the like is included as a failure point, and if a failure point signal of a rope failure point is received, the code of the rope failure point is the target failure point code. The number of target fault point codes is not particularly limited.

Each fault point position in the belt fault point list corresponds to a fault point type and also corresponds to a fault point code, and when a target fault point code is determined, the corresponding target fault point type and the target fault point position can be inquired in the belt fault point list through the target fault point code.

TABLE 1 list of belt failure points

According to the method for diagnosing the belt shutdown fault of the belt conveyor, the belt fault point list comprises the corresponding relation among the fault point positions, the fault point types and the fault point codes. After a fault point signal of the belt is received and a target fault point code is determined, the type and the position of a corresponding target fault point are inquired in a belt fault point list through the target fault point code, so that the type and the position of a belt shutdown fault can be rapidly determined, and the efficiency of searching for the belt shutdown fault of the belt conveyor is improved.

Based on the foregoing embodiments, fig. 2 is a flowchart of a process for establishing a belt failure point list according to an embodiment of the present application, where the process for establishing the belt failure point list includes:

s20: and acquiring the position and the corresponding type of the fault point.

S21: and generating a fault point code corresponding to the fault point position.

S22: and establishing a belt fault point list according to the corresponding relation among the fault point positions, the fault point types and the fault point codes.

In step S20, the failure point position refers to the position of each detection point and linkage point, each failure point position corresponds to one failure point type, and the failure point types corresponding to different failure point positions are the same, for example, as in table 1, 1# cord failure, 2# cord failure, 3# cord failure, etc., 1#, 2#, and 3# indicate cords at different positions, but the corresponding failure point types are all cord failures. The position of the fault point can be obtained according to the positions of the detection point and the linkage point, and the mode of obtaining the position of the fault point is not particularly limited. The number of the fault point positions and the fault point types is not particularly limited.

In step S21, the failure point positions are encoded, one failure point position corresponding to one failure point code.

In step S22, the correspondence relationship refers to that each fault point location corresponds to a fault point code, and each fault point location also corresponds to a fault point type, so that the fault point code, the fault point type and the fault point location correspond to one another one by one, and then knowing the fault point code, the fault point type and the fault point location can be determined.

According to the method and the device, the belt fault point list containing the corresponding relation among the fault point positions, the fault point types and the fault point codes is established, the fault point types and the fault point positions can be determined when the fault point codes are obtained, the fault point types and the fault point positions included in the fault point list are comprehensive, the belt shutdown faults are analyzed according to work experience, and the efficiency of finding the fault point types and the fault point positions is improved by calling the fault point list.

Based on the above embodiments, regarding receiving a fault point signal of a belt, the embodiments of the present application receive an activation signal of a set end of an SR flip-flop; the set end of the SR trigger is used for receiving the fault point signal and blocking the fault point signal.

Fig. 3 is a structural diagram of an SR flip-flop according to an embodiment of the present application, where Q and Q are not two output terminals of the SR flip-flop; s and R are two input terminals of the SR flip-flop, R is usually called a Set 0 terminal or a Reset terminal, S is a Set 1 terminal or a Set terminal, R is an abbreviation of Reset, and S is an abbreviation of Set. Each fault point is connected with a set end of one SR trigger, and after receiving the fault point signal, the SR trigger blocks the fault point signal. It can be understood that whether the embodiment of the present application receives the fault point signal through the SR flip-flop does not affect the implementation of the embodiment of the present application.

Based on the embodiment, when the target fault point is determined according to the fault point signal, the target fault point type and the target fault point position corresponding to the target fault point code are determined through the belt fault point list, and after the fault is cleared, the reset end of the SR trigger is activated, so that the SR trigger clears the blocking of the fault point signal.

The SR trigger is used for receiving the fault point signal and blocking the fault point signal, so that the flashed fault point signal, such as poor line contact and belt shutdown caused by component aging, can not be kept all the time, and is blocked by the SR trigger so as to avoid the situation that the signal sent by the fault point is not found in time. After the fault is cleared, the reset end of the SR trigger is activated, the blockage of the fault point signal is cleared, and the SR trigger is convenient to receive the next fault point signal.

Based on the embodiment, after the belt fault point list is established, corresponding alarm points can be set according to the fault point positions, the fault point types and the fault point codes, and all the alarm points are displayed in the same monitoring picture.

Fig. 4 is a schematic diagram of an alarm point monitoring screen according to an embodiment of the present application, where, as shown in fig. 4, all alarm points are displayed in the monitoring screen, each alarm point includes information about a fault point type, a fault point code, and a fault point position, and a rectangular small box is corresponding to the rear of each alarm point, and the small box is an alarm indicator. The output position of the target failure point code is at the upper left position in fig. 4. The number of alarm points in the embodiment of the present application is not limited, and is not limited to the number of alarm points in fig. 4, and certainly, the alarm points may be displayed on the same monitoring screen or on different monitoring screens.

This application embodiment is through showing whole warning points in same control picture, is favorable to the staff to carry out real-time supervision, masters the condition that the belt shut down trouble fast.

Based on the embodiment, after the type and the position of the target fault point corresponding to the target fault point code are determined through the belt fault point list, whether the belt normally runs or not is judged, and if not, an alarm is sent through the target alarm point corresponding to the target fault point code.

The alarm in the embodiment of the application can be that when the belt is stopped, the indicator light of the target alarm point is changed from green to red, the indicator light can flash or the alarm point rings, and the alarm form is not specifically limited in the embodiment of the application.

According to the embodiment of the application, the alarm is sent out through the target alarm point corresponding to the target fault point code, so that a worker can be intuitively informed that the belt of the rubber belt conveyor has a halt fault, the target fault point code is displayed in a monitoring picture, and the worker is informed of the type and the position of the halt fault of the belt.

Based on the above embodiment, a plurality of groups of protection detection devices are arranged in the electrical control of the belt conveyor, and a plurality of chains exist among the devices, for example, the rope pulling device detects a rope pulling fault which causes the belt of the belt conveyor to stop, once the belt stops, a relay for controlling the emergency stop responds to the belt stop, and at this time, an SR trigger connected with an integrated emergency stop fault point receives a fault point signal and outputs a corresponding target fault point code, but the integrated emergency stop is not the cause of the belt stop fault. Since the belt conveyor has not only a linkage in the electrical control but also a linkage in the control program, that is, one fault point action may cause other fault points to respond, after the target fault point code is output according to the fault point signal, the output sequence of the target fault point code is determined, and the target fault point code of the first bit in the output sequence is displayed in the monitoring screen.

The output sequence is the time sequence of the target fault point output, and the target fault code output firstly, namely the target fault point arranged at the first position in the output sequence is displayed in the monitoring picture.

According to the method and the device, the output sequence of the target fault point codes is determined, and the first target fault point code in the output sequence is displayed in the monitoring picture, so that the fault finding time can be shortened, a worker can determine the position and the type of the fault point at the first time, and the efficiency of finding the belt stop fault of the belt conveyor is further improved.
