Gate detection method and gate control system

The invention provides a gate machine detection method and a gate machine control system. The gate machine detection method comprises the steps that a gate machine executes door opening and closing actions; light spot sensing information of the gate is output in real time; detecting the real-time state of the gate according to the light spot sensing information; the gate machine is corrected; according to the gate machine detection method and the gate machine control system, existing photoelectricity in a gate machine channel is fully utilized to achieve limiting, the internal structure of the gate machine can be simplified, and device loss caused by rigid collision to the gate machine is reduced; the real-time running state of the gate is detected according to light spot sensing information, angle detection can be conducted on any key node of the gate, meanwhile, the linear speed and the angular speed of the gate in the forward and reverse door opening and closing process can be detected, and the method can
