Background
The automatic ticket checking machine (hereinafter referred to as gate) is an important component of an automatic fare collection system (AFC system) for rail transit, and the gate realizes the automatic ticket checking function by effectively identifying passenger ticket card information and effectively judging the passing behavior in a channel, thereby ensuring that passengers smoothly pass in and out of the gate and assisting a networked toll collection system to charge. The performance level and the intelligent level of the gate directly influence the passing safety and the passing efficiency of passengers and influence the income of rail transit operation companies. The passing logic is a core logic algorithm for automatically judging the passing behavior of passengers in a gate passage, ensuring the passengers to pass the gate normally by controlling the movement of the door leaves and preventing invalid passengers from running the gate. The passing logic is an important component in an automatic ticket checking system, and is a key point for realizing the intellectualization of an AFC system and ensuring the passing safety of passengers and the passing efficiency of a gate.
Due to the importance of the traffic logic, the detection of the gate traffic logic is one of the most important detection contents of the rail transit network equipment management department. The initial detection is manually carried out by testers, at least ten testers with different heights, weights and sexes are required according to the functional test requirements, the test is carried out by the testers wearing clothes with different colors, the test efficiency is low, the result randomness is high, and the result is unstable. In order to improve the testing efficiency, testing centers in various places are exploring to perform tests using testing robots. One type of detection robot is that a human body model is installed on an automatic traction trolley and circularly rotates on a fixed annular slide way, so that the passing of passengers through a brake can be quickly simulated, and the quick detection on the passing logic function and the reliability can be realized. But because the annular slideway is over-heavy and the test noise is too large, the annular slideway is not suitable for field test. On the basis of the testing robot, the annular track is increased to a height above the gate, the mode of driving the annular track by an aluminum alloy structure and a rubber belt is changed, a second testing robot is formed, the weight of equipment is reduced, and noise is reduced. However, the equipment volume is large, two to three gate channels are required to be occupied during testing, and large-scale testing is not required to be carried out. A human body model is installed on an AGV (automatic guided vehicle) guided by laser in the third type of testing robot, and the AGV can move according to a prefabricated track and has a safety protection function of automatically stopping when encountering obstacles. However, the human body model and the real passenger brake-passing behavior are different, the testing accuracy is not enough, and the testing robot is too expensive and does not have the condition of large-range testing.
