Example Embodiment
[0022] Embodiment 1: The control system for detecting the safe area by combining infrared light and ultrasonic waves is composed of a PC microcomputer, a main controller and a sensor.
[0023] PC microcomputer: The PC microcomputer adopts the window dialogue interface control mode to realize the parameter and status setting of the main controller.
[0024] Main controller: The main controller output control adopts single-column operation, bus-type convergence and priority classification identification of ultrasonic ranging detection. Four single-chip single-chip AT89C2051 independent single-column detection operations are carried out by serial communication in the main control CPU single-chip AT89S8253. Priority recognition and judgment, sensor number and detection distance numerical display and communication bus control of external PC microcomputer parts.
[0025] The external transmission power supply (+V) is connected in parallel with the filter capacitors C1 and C2 to the ground,...
