Transportation automobile intelligent electric apparatus box

Abstract

The invention discloses a transportation automobile intelligent electric apparatus box. An LINE circuit comprises integrated circuits U53-U55, diodes D51-D52, resistors R191-R198, a resistor R52, resistors R11-R12, resistors R37-R38, resistors R58-R59 and capacitors C202-C208. Centralized control is adopted, small modules are canceled, wiring harnesses of the transportation automobile intelligentelectric apparatus box are reduced, the total weight of the wiring harnesses is reduced, all the small modules are integrated to achieve centralized control, module cost, wiring harness connection andconnectors between the wiring harnesses and the modules are reduced, cost is reduced, contact faults between the modules are reduced, the mode that weak current controls strong current is adopted, the diameter of each wiring harness is reduced, the weight of the wiring harnesses is further reduced, maintenance is more convenient and quicker, high and low levels can be effectively input or input at the analog quantity through an input port, and configuration is flexible. By the adoption of the scheme, the requirements for connection and control of various automobile electric apparatuses can bemet, and circuits are simple, convenient to use, centralized and convenient to install and overhaul.

Description

technical field [0001] The invention relates to the technical field of automobile electric appliances, in particular to an intelligent electric appliance box for a transportation automobile. Background technique [0002] If the engine is compared to the heart of a car, then the smart electrical box is the central nervous system of the car. The smart electrical box is responsible for conveying driving information to various parts of the car body. One of the parts with higher requirements and stricter process requirements. [0003] With the development of modern society and the rapid improvement of technology, family cars are becoming more and more comfortable and user-friendly, but commercial vehicles such as heavy trucks, light trucks and heavy machinery with 24V systems are relatively backward, and the roads generally required by commercial vehicles are also The road conditions are relatively poor, the car body is violently bumpy, and traditional fuse boxes are generally u...

Problems solved by technology

[0003] With the development of modern society and the rapid improvement of technology, family cars are becoming more and more comfortable and humanized, but commercial vehicles such as heavy trucks, light trucks and heavy machinery and other 24V systems are relatively backward, and the roads generally required by commercial vehicles are also different. The road conditions are relatively poor, the car body is violently bumpy, and traditional fuse boxes are generally used. There are too many small modules, and there are many wiring harness connections that need to be used. Due to its own characteristics, the failure rate is high and the maintenance is relatively cumbersome. It is urgent to change the technical control of commercial vehicles in the 24 system to meet the needs of the development of the times.
