Description

TECHNICAL FIELD

[0001] The present application relates to the field of testing technology of the inner door of the motor train unit, in particular to a motor train unit inner door anti-pressing tester. BACKGROUND

[0002] In the motor train unit "inner door system test", the tester manually prevents the inner door from closing 5 times to test whether the anti-pressing function of the inner door is effective. The tester needs to hide in a small corner outside the inner door and use a wooden block to block the door frame to simulate the door pressing. If the position is not appropriate during the operation, the human body's thermal infrared radiation is easy to trigger the upper infrared sensor of the inner door, causing the door to open automatically. The anti-pressing test fails, and this test needs to be performed again, which wastes time and is inefficient. SUMMARY

[0003] The present application provides a motor train unit inner door anti-pressing tester to solve the problems of test failure, time waste and low test efficiency caused by manual operation in the existing motor train unit inner door anti-pressing test.

[0004] The motor train unit inner door anti-pressing tester comprises a support assembly, a comprehensive module and an inner door anti-pressing module.

[0005] The support assembly comprises a base, a heavy block and a support rod; the support rod and the heavy block are both installed at both ends of the base.

[0006] The comprehensive module comprises a counting processing unit, a power supply, a display unit, a voice alarm unit, a wireless transmission unit and an electrical connector which are electrically connected to the counting processing unit; the power supply supplies power to each unit.

[0007] The inner door anti-pressing module is installed on the support rod, and the anti-pressing test of the inner door at different heights is realized by the lifting of the support rod.

[0008] The comprehensive module is arranged on the heavy block of the support assembly and connected to the inner door anti-pressing module through a connecting line. The comprehensive module collects the anti-pressing times of the inner door detected by the inner door anti-pressing module, counts through the counting processing unit, displays the counting information through the display unit and issues a prompt through the voice alarm unit.

[0009] The tester of the present application can effectively prevent the interference of the human body on the thermal infrared door opening device of the inner door of the motor train unit by making a professional and standardized inner door anti-pressing module and a stable support that can be lifted, ensuring the realization of the anti-pressing function of the inner door. The device also records the anti-pressing times through a general electronic counter. When the number of times reaches the test requirement, the number of times and the test completion situation are sent to the display screen, and the completion situation of the test data can be remotely monitored through a mobile phone, a tablet or other devices with Bluetooth or WIFI function.

[0010] The tester can simplify the operation process, does not need manual operation to prevent extrusion during the test process, is accurate and reliable in counting, reduces labor intensity, realizes one-key intelligent automatic operation, and improves the test success rate.
