Timing system for robot labyrinth

Abstract

The embodiment of the invention relates to the field of communication, in particular to a timing system for a robot labyrinth. The system comprises a starting point signal detection device, an end point signal detection device, a signal receiving device and an upper timing device. The starting point signal detection device comprises a starting point laser emitting module and a starting point illuminance detection module which are located at the starting point of the labyrinth and oppositely arranged; the laser emitting module emits laser to the starting point illuminance detection module; when the tracing robot passes through the starting point to shield the laser, the laser intensity detected by the starting point illuminance detection module is smaller than a first threshold value, and a starting signal is sent to a signal receiving device; and similarly, the end point signal detection device sends an end point signal, and the upper timing device performs timing according to the starting point signal and the end point signal. The laser beams emitted by the laser emission module are high in directivity, so that interference generated by light beam scattering is avoided, and the accuracy of the timing system is improved; and the detection speed of the starting point illuminance detection module is high, and the response speed of the timing system is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a timing system for a robot maze. Background technique [0002] The miniature tracking robot competition usually uses an automatic timing system to assist the referee to time the contestants. The existing automatic timing system is to install an ultrasonic distance measuring device at the starting point and end point of the maze. When the miniature tracking robot passes by, the distance measured at this time is less than the set value. After the controller judges, it sends a start signal or an end signal. [0003] There are certain defects in this detection method. The specific manifestations are: because the distance measurement of the ultrasonic distance measuring device takes a long time and the response speed is slow, when the micro tracking robot sprints at high speed, it is easy to cause the missing detection of the starting point signal and the ending point signal, resulting in ...
