The transmitting end of the first transmitter 11 is aligned with the receiving end of the first receiver 12. The signal transmitted by the transmitting end of the first transmitter 11 is received by the receiving end of the first receiver 12. If there is a vehicle between the first transmitter 11 and the first receiver 12, then the signal between the first transmitter 11 and the first receiver 12 is blocked.
[0033] The second set of sensors 2 includes a second transmitter 21 and a second receiver 22. Both the second transmitter 21 and the second receiver 22 are installed on the corridor 4.

[0036] The alarm mechanism 3 further comprises a first time relay 33 and a second time relay 34, the first time relay 33 is in signal connection with the first group of sensors 1, and the second time relay 34 is in signal connection with the second group of sensors 2, because there are many vehicles passing through every day, in order to reduce unnecessary alarms, the first time relay 33 and the second time relay 34 have a delay triggering effect respectively, that is, the alarm of the first alarm 31 and the second alarm 32 is delayed.
[0037] When a vehicle passes through or stays between the first transmitter 11 and the first receiver 12, the signal between the first transmitter 11 and the first receiver 12 is interrupted, the first time relay 33 sets a delay time to trigger the first alarm 31 and the second alarm 32, if the signal between the first transmitter 11 and the first receiver 12 is connected before the delay time, then the first alarm 31 and the second alarm 32 do not need to be triggered, if the signal between the first transmitter 11 and the first receiver 12 is interrupted for more than the delay time, then the first time relay 33 triggers the first alarm 31 and the second alarm 32.
[0038] When the vehicle passes or stays between the second transmitter 21 and the second receiver 22, the signal between the second transmitter 21 and the second receiver 22 is interrupted, the second time relay 34 sets a delay time to trigger the first alarm 31 and the second alarm 32, if the signal between the second transmitter 21 and the second receiver 22 is connected before the delay time, the first alarm 31 and the second alarm 32 are not triggered, if the signal between the second transmitter 21 and the second receiver 22 is interrupted more than the delay time, the second time relay 34 triggers the first alarm 31 and the second alarm 32.
