Detailed ways

In the accompanying drawings, the single-chip computer-based material truck position detection system includes several groups of photoelectric pair tubes 2 uniformly installed along the running channel of the material truck 1 to judge the position of the material truck 1 and communicate with each group of photoelectric pair tubes 2 respectively. Connected single-chip microcomputer 5, photoelectric pair tube 2 sends signal to single-chip microcomputer 5 and carries out signal processing by single-chip microcomputer 5; Said single-chip microcomputer 5 is also connected with alarm 6, nixie tube display module 7 and memory EEPROM8, and by RS485 interface 4 and computer 3 Realize the communication connection.

Each group of photoelectric pair tubes 2 includes a laser diode (LD) and a laser diode (PD), which are installed on both sides of the transmission line. The laser diode (LD) on one side is used as a projection light source, and the laser diode ( PD) array is used as a light-receiving sensor, and the detection of the photoelectric tube 2 on the material truck 1 is based on whether the light received by the light-receiving sensor is blocked to determine the position of the material truck 1.

After the photoelectric pair tube 2 detects the feeder 1 and disconnects the relay, the photoelectric pair 2 detects the position of the feeder 1 again, and if it detects that the feeder 1 exceeds or falls below the corresponding position, the single-chip microcomputer 5 will control the The alarm 6 sends an alarm sound, and the position of the feeding car 1 is displayed by the nixie tube.
