Embodiment Construction
[0009] The present invention will be further described below in conjunction with the accompanying drawings.
[0010] Figure 1 is a block diagram of the signal control machine system, which mainly includes five parts: PIC microcontroller, color lamp driver, vehicle detection, fault self-test and Ethernet networking.
[0011] The PIC microcontroller is the control core of the signal control machine system. It automatically detects the control switch selection status of the signal control machine panel when it is turned on, determines the control mode, enters the corresponding control processing program, and executes the basic signal control functions of the signal machine. The LED part of the system displays The current program information of the signal control machine, the user can use the keyboard to modify the control program. The system also has an RS-485 vehicle detection interface. The vehicle detection system transmits the externally detected traffic flow data to the sing...
