Abstract

The invention discloses an electro-hydraulic intelligent distributed controller which comprises a CPU (Central Processing Unit) circuit (1), an A / D (Analog-to-Digital) acquisition circuit (2), a digital output circuit (3), a digital input circuit (4), a power supply circuit (6) and a CAN (Controller Area Network) bus communication circuit (5), wherein the power supply circuit (6) is output to power supply input ends of other circuits; the CPU circuit (1) is connected with printed conductors of other circuits; an external power supply is converted by the power supply circuit (6) into three power supplies required by the controller; external input and communication data collected by the A / D acquisition circuit (2), the digital input circuit (4) and the CAN bus communication circuit (5) are logically processed and calculated by the CPU circuit (1); and closed-loop control on external load and bus communication are realized through the digital output circuit (3) and the CAN bus communication circuit (5). The controller with the automotive electronics and bus technology has a wider application prospect in the fields of special vehicles, engineering machinery and factory automation.

Description

technical field [0001] The invention relates to an electronic controller, in particular to an electro-hydraulic intelligent distributed controller. Background technique [0002] At present, most special vehicles and construction machinery equipment control systems use a centralized CPCI bus controller as the control core. The centralized CPCI bus controller has centralized and complex functions, and its components mainly include CPU boards, I / O boards, board, communication board, power board and backplane, etc. The CPU board, I / O board, A / D board, communication board, and power board are connected to the backplane through special connectors. Because the control mode of the centralized CPCI bus controller is highly centralized, a partial failure may cause the overall failure of the system, reducing the reliability and scalability of the system. Contents of the invention [0003] The purpose of the present invention is to provide an electro-hydraulic intelligent distribute...
