[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] In order to improve the test efficiency of the door control system, the present application discloses a test controller for a rail vehicle door system. Refer to Figure 1 , the system can:

[0028] A door control signal generator 100, a first solid-state relay K1, a second solid-state relay K2, a first time-delay relay D1, a third solid-state relay K3, and a counter 200;

[0029] The door control signal generator 100 is used to generate and output a door control signal based on a preset frequency. The door control signal generator 100 can generate and output an enable signal based on a preset frequency, and this enable signal can be directly used as the door control signal. The door control signal generator 100 can also be composed of a pulse signal generator and a trigger. The pulse signal generator preset frequency generates and outputs a pulse signal. After the pulse signal acts on the trigger, a door control signal with the required amplitude is generated by the trigger. For example, every time the trigger detects a pulse signal, a door control signal with a preset amplitude is generated and the door control signal is sent to the first solid-state relay K1;

[0030] The first solid-state relay K1 is used to obtain and forward the door control signal;

[0031] The second solid-state relay K2, the input end of the second solid-state relay K2 is connected to the output end of the first solid-state relay K1, and the output end of the second solid-state relay K2 is connected to the gate control signal input ends of each door control system. In this solution, the second solid-state relay K2 obtains the door control signal through the first solid-state relay K1 and sends the door control signal to the gate control signal input end of the door control system. After obtaining the gate control signal, the door control system performs an operation on the door based on the current state of the door. For example, if the door is in the open state, a closing operation is performed on the door; if the door is in the closed state, an opening operation is performed on the door. Of course, the door control system may also have two gate control signal input ends. One of the gate control signal input ends is connected to the output end of the second solid-state relay K2, and the door control signal obtained from this gate control signal input end is only used as an opening signal. The other control signal input end is connected to the output end of the third solid-state relay K3, and the door control signal obtained from this gate control signal input end is only used as a closing signal;

[0032] The first delay relay D1, the input end of the first delay relay D1 is connected to the output end of the first solid-state relay K1. In this solution, after the first delay relay D1 delays the door control signal output by the first solid-state relay K1, it is loaded onto the door control system through the third solid-state relay K3, so that the door control system responds to the door control signal output by the third solid-state relay K3 again after a set duration of responding to the door control signal output by the second solid-state relay K2. The set duration is the delay duration of the first demonstration machine relay;

[0033] The third solid-state relay K3, the input end of the third solid-state relay K3 is connected to the output end of the first delay relay D1, and the output end of the third solid-state relay K3 is connected to the gate control signal input ends of each door control system;

[0034] The counter 200, the output end of the counter 200 is connected to the output end of the first solid-state relay K1, and is used to count the number of times of the door control signal output by the first solid-state relay K1. Through the counted number of times of the counter 200, the test times of the door control system can be obtained. For example, if the count of the counter 200 is 100, then the door control system has performed 100 times of door opening and closing tests.

[0035] Using the technical solution disclosed in the embodiment of the present application, when starting the gate control signal generator 100, the gate control signal generator 100 will generate and output a gate control signal based on a preset frequency. After the gate control signal sequentially passes through the second solid-state relay K2, the first time-delay relay D1, and the third solid-state relay K3, a set of gate control signals will be generated. The gate control signals include a door closing signal and a door opening signal. After the gate control system obtains the gate control signals, it performs the door opening operation and the door closing operation, completing an opening and closing test. Moreover, the test times of the gate control system can be recorded by the counter 200 to prevent the test times of the gate control system from being too few to reliably test the gate control system, thereby improving the test efficiency and ensuring the reliability of the test results.

[0036] In the technical solution disclosed in another embodiment of the present application, referring to Figure 2 , it may further include a second time-delay relay D2, and the second time-delay relay D2 is arranged between the first solid-state relay K1, the second solid-state relay K2, and the first time-delay relay D1. That is, the input end of the second time-delay relay D2 is connected to the output end of the first solid-state relay K1, and the output end of the second time-delay relay D2 is connected to the input end of the second solid-state relay K2 and the input end of the first time-delay relay D1. At this time, the gate control signal input to the second time-delay relay D2 is only delayed by the second time-delay relay D2, and the gate control signal input to the third solid-state relay K3 is delayed by the first time-delay relay D1 and the second time-delay relay D2.

[0037] In the technical solution disclosed in another embodiment of the present application, it may further include a start switch arranged between the first solid-state relay and the second time-delay relay D2. Only when the start switch is closed, the gate control signal output by the first solid-state relay K1 can be sent to the second time-delay relay D2.

[0038] In the technical solution disclosed in another embodiment of the present application, the first time-delay relay D1 and the second time-delay relay D2 are adjustable time-delay relays.

[0039] In the technical solution disclosed in another embodiment of the present application, in order to facilitate the user to observe and record the test times of the gate control system, a recorder 400 may further be included in the above solution. The recorder 400 is used to read and display the count value of the counter 200. The user can determine whether to continue to test the gate control system based on the recorded value of the recorder 400.

[0040] In the technical solution disclosed in another embodiment of the present application, it further includes: a power supply module 300, which is used to provide working current for the electrical devices in the test controller of the rail vehicle door system. Its input end is connected to an external power supply. After converting the electrical signal obtained from the external power supply, it is converted into a working power supply suitable for the counter 200 or other electrical devices in the technical solution disclosed in the embodiment of the present application and then output.

[0041] Further, in the technical solution disclosed in the above embodiment of the present application, a control switch is provided on the power supply module 300, and the control switch is used to control whether the power supply module 300 works.
