Highly integrated engineering machinery control system based on CAN bus

Abstract

The invention discloses a highly integrated engineering machinery control system based on a CAN (Controller Area Network) bus, which comprises a combined key (CAN), a radio (CAN), a wiper motor (CAN), a water spray motor (CAN), a light (CAN), a sensor (CAN), an input node (CAN), an output node (CAN), an instrument (CAN), an engine unit (engine ECU (Electronic Control Unit)), an electromagnetic valve output node (CAN) and an engine bus. The system is characterized in that the combined button (CAN), the radio (CAN), the wiper motor (CAN), the water spray motor (CAN), the light (CAN), the sensor (CAN), the input node (CAN), the output node (CAN), the instrument (CAN), the engine ECU (CAN) and the solenoid valve output node (CAN) are all connected in parallel through a CAN bus.

Description

technical field [0001] The invention relates to the technical field of electrical control, in particular to a highly integrated engineering machinery control system based on a CAN bus. Background technique [0002] In the field of construction machinery monitoring systems, the technical status of similar products in terms of control methods, all use ordinary mechanical methods such as knobs and switches, and directly control the execution components through lines; electrical components, such as radios, lights, wiper motors, water spray Motors, solenoid valve groups and other equipment are all independently controlled and complicated to operate; sensors are all switch data or analog data; wiring harness design is cumbersome, wiring is complex, and wiring is dense, almost all point-to-point design ideas. In the process of design, wiring, assembly, etc., it is extremely time-consuming, and the wire harness raw materials are used too much, which wastes resources. [0003] In te...

AI Technical Summary

Problems solved by technology

[0002] In the field of construction machinery monitoring system, the current state of technology of similar products adopts ordinary mechanical methods such as knobs and switches, and directly controls the executive components through lines; electrical components, such as radios, lights, wiper motors, water sprays, etc. Motors, solenoid valves and other equipment are all independently controlled, and the operation is cumbersome; the sensors are all switch data or analog data; the design of the wiring harness is cumbersome, the wiring is complicated, and the wiring is dense, almost all of which are point-to-point design ideas

In the process of design, wiring, assembly, etc., it is extremely time-consuming, and the wiring harness materials are used too much, which wastes resources

[0003] In terms of the whole system: the control method is scattered, complex, low degree of integration, low product stability, all are single-loop control methods; no fault prompts, low degree of intelligence, resulting in extremely inconvenient operation and maintenance

[0004] In terms of electrical components: cumbersome control, low degree of intelligence, no electrical device failure alarm function

[0005] In terms of software: there is no standard, systematic and comprehensive communication protocol, resulting in a blank market

[0006] In terms of wiring harness design: there are problems such as high cost of raw materials, complex design, cumbersome process, and high man-hours for production and installation.
