Again by the positional relationship compared with second threshold.
6. the anti-pinch object space method of escalator according to claim 3, which is characterized in that the comparison result includes described
Positional relationship and first threshold and the size relation between second threshold；
The output reduction of speed instruction when positional relationship is less than first threshold, and is more than or equal to second threshold；
Halt instruction is exported when positional relationship is less than second threshold.
7. the anti-pinch object space method of escalator according to claim 1, which is characterized in that the current staircase speed of service is
V0；
It is V that the reduction of speed, which instructs the corresponding staircase speed of service,1；
And V1For V01/5~1/10.
8. the anti-pinch object space method of escalator according to claim 3, which is characterized in that the anti-pinch object space method is also wrapped
It includes, when the positional relationship is more than or equal to first threshold, maintains the current staircase speed of service.
9. a kind of computer equipment, including memory and processor, which is characterized in that the memory is stored with computer program
It loads and executes for the processor:
Receive detection signal relevant to moving object position；
The positional relationship between mobile object and test point is calculated according to the detection signal；
The positional relationship is obtained into comparison result compared with threshold value；
Reduction of speed instruction or halt instruction are exported when the comparison result meets default.
10. a kind of anti-pinch object system of escalator, which is characterized in that including configure test point sensor and with it is described
The control unit of sensor communication connection, the sensor detection mobile object are simultaneously relevant to moving object position by what is obtained
Detection signal is sent to described control unit；
Described control unit receives detection signal relevant to moving object position；Mobile object is calculated according to the detection signal
Positional relationship between test point；The positional relationship is obtained into comparison result compared with threshold value；When the comparison result accords with
The instruction of output reduction of speed or halt instruction when closing default.
