The invention discloses a logic control board of an all-terrain vehicle power distribution system, which comprises a power supply module arranged on a PCB circuit board, a CPLD system module, an LED display module, and an instrument connected to the input end of the CPLD system module and having an input isolation circuit A signal input unit and a fuel logic input unit, an instrument signal output unit and a fuel logic output unit connected to the output terminal of the CPLD system module and having an output isolation circuit. The present invention adopts an independent modular design, uses the isolation circuit to realize the isolation of the system input unit, the system output unit and the CPLD system module, and ensures the stability of the centralized processing signal logic of the CPLD system module, and the interaction between the signal logic input and output actions No interference impact, greatly improving the stability of power distribution. Simultaneously, the present invention uses the photoelectric coupler as the main component, forms a simple circuit module to isolate and convert the signal, and fully satisfies the signal display logic requirement and the fuel control logic requirement of the all-terrain vehicle.
Description
technical field [0001] The invention relates to a logic control board of an all-terrain vehicle power distribution system, which belongs to the technical field of vehicle power distribution control. Background technique [0002] The all-terrain vehicle is a multi-functional engineering transportation platform with high speed, high passability and high maneuverability, which can complete engineering operations such as emergency rescue and disaster relief and special transportation under harsh geographical environments and complex weather conditions. The car has high requirements on stability, failure rate, reliability and intelligence. As a key system, the power distribution control system's stability directly affects the work efficiency and reliability of the all-terrain vehicle. However, in the current market, the signal logic input elements of the power distribution system of all-terrain vehicles directly control the output action actuators, or indirectly control but the ...
