For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The present invention provides a system and method for predicting the life of a target controller board. Figure 1 As shown. The system for predicting the life of a target controller board comprises: a target controller system 100, wherein the target controller system 100 comprises a target controller board using a safety relay, and can collect the number of times the safety relay operates; a maintenance terminal 200, which is connected to the target controller system 100 through a network interface to achieve information interaction with the target controller system 100. Further, the maintenance terminal 200 can be used to obtain information about the number of times the safety relay operates from the target controller board, and estimate the service life of the target controller board by analyzing the number of times the safety relay operates.

[0036] The target controller system 100 is also connected to the motor control center (MCC) for communication, and drives the trackside signal equipment through the drive command issued by the motor control center (MCC). The drive of the trackside signal equipment includes the drive of the signal machine, turnout, track circuit and other equipment.

[0037] The target controller system 100 further comprises a data recording and analysis module and a data storage module. The data recording and analysis module records and accumulates the number of actions of the safety relay, and stores the accumulated total number of actions in the data storage module.

[0038] Wherein, the maintenance terminal 200 includes a data analysis and calculation module and a display interface. The data analysis and calculation module is used to analyze and calculate the total number of actions transmitted from the target controller system 100 to the maintenance terminal 200, specifically: the total number of actions of the safety relay received from the target controller board and the set maximum number of times that the safety relay can act (hereinafter referred to as the threshold) are analyzed and calculated to obtain the percentage information of the total number of times the safety relay has acted to the threshold, and the service life of the target controller board is estimated accordingly. The display interface can display information such as the total number of actions of the safety relay, the percentage of the total number of actions to the threshold, and the estimated service life of the target controller board. When the percentage of the total number of actions of the safety relay to the threshold exceeds the set safety percentage, it indicates that the target controller board is about to reach its service life, and the display interface will send an alarm signal.

[0039] The maintenance terminal 200 is connected to the target controller system 100 via Ethernet 300. Furthermore, data transmission between the two can be carried out via UDP protocol (i.e., User Datagram Protocol). The UDP protocol is particularly suitable for the case of large initial data volume and non-secure communication.

[0040] The present invention also provides a method for predicting the life of a target controller board. Figure 2 As shown in the figure, this method is based on the analysis of the number of safety relay actions and includes the following execution steps:

[0041] Step S1, the target controller system 100 accumulates the number of times the safety relay operates to obtain a total number of times of operation;

[0042] In step S2, the target controller system 100 sends the total number of actions to the maintenance terminal, and the maintenance terminal analyzes the total number of actions and estimates the service life of the target controller board.

[0043] Wherein, the step S1 is specifically implemented by the following sub-steps:

[0044] Step S1.1, power on the target controller system 100 to complete the initialization operation;

[0045] Step S1.2, within a fixed period, the target controller system 100 receives a drive command from the motor control center (MCC), and drives the trackside signal device according to the drive command;

[0046] The fixed period is a main driving period in the target controller system 100. In a specific embodiment of the present invention, the fixed period is 250 ms.

[0047] Step S1.3, when the trackside signal device is driven, the target controller system 100 works synchronously, and the safety relay follows the action. Within a fixed period, the target controller system 100 collects the number of actions of the safety relay according to the action of the safety relay;

[0048] Step S1.4, the target controller system 100 performs a system self-check periodically (i.e., several fixed cycles), and on the premise of ensuring that the system is normal, the number of actions of the safety relay collected by the target controller system 100 in several fixed cycles is accumulated to obtain the total number of actions. In addition, when the target control system 100 performs a self-check, the safety relay also works synchronously.

[0049] Wherein, the step S2 is specifically implemented by the following sub-steps:

[0050] Step S2.1, the maintenance terminal 200 obtains the total number of actions of the safety relay in the target controller system 100 by means of the UDP protocol;

[0051] Step S2.2, the maintenance terminal 200 analyzes and calculates the total number of safety relay actions received and the set threshold value, obtains the percentage information of the total number of safety relay actions to the threshold value, and estimates the service life of the target controller board accordingly;

[0052] Step S2.3, displaying the total number of actions of the safety relay, the percentage of the total number of actions to the threshold, and the estimated service life of the target controller board through the display interface set on the maintenance terminal 200. When the percentage of the total number of actions of the safety relay to the threshold exceeds the set safety percentage, it indicates that the target controller board is about to reach the end of its service life, and the maintenance terminal 200 issues an alarm.

[0053] In actual use, based on existing equipment, by running the execution steps of the above-mentioned method for predicting the life of the target controller board, the number of actions of the safety relay in the target controller board is obtained, and the calculation and processing are performed in the maintenance terminal 200. Finally, the total number of actions of the safety relay, the percentage of the current total number of actions to the threshold, and the estimated life of the target controller board are displayed through the display interface.

[0054] After the life prediction test of the target controller board is completed, the above steps S1.2 to S2.3 are repeated, that is, the number of actions of the safety relay of the next target controller system 100 is recalculated and accumulated, and sent to the maintenance terminal 200 to realize another estimation of the service life of the safety relay.

[0055] In summary, the system and method for predicting the life of a target controller board provided by the present invention can conveniently monitor the number of actions of the safety relay in the target controller board, and transmit the accumulated total number of actions to the maintenance terminal, thereby estimating the service life of the target controller board, greatly improving the stability of rail transit operations and reducing maintenance pressure.
