General module for bus vehicle mounted network and information integration control system

Abstract

The invention discloses a general module used in a bus vehicle network and an information centralized control system, which comprises a microcontroller, a CAN communication circuit, a frequency acquisition circuit, an analog acquisition circuit, a switch acquisition circuit, a resistive leakage load driving circuit, a perceptual load driving circuit, a power supply circuit and a reset circuit. The microcontroller is respectively connected with the output terminal of eight circuits through a data bus. The CAN communication circuit receives the control signal and the related information of the switch acquisition circuit, the frequency acquisition circuit and the analog acquisition circuit from a sending module through a CAN bus; and then control information is formed after being processed by the microcontroller, which is sent to a receiver module through the CAN bus to activate the resistive leakage load driving circuit and the perceptual load driving circuit to move. Generalization is realized by the module which is of convenient to be debugged and maintained; the comprehensive cost is reduced; the need of a common bus vehicle network system is satisfied and the personalized customization is realized; the bus control is realized, which is of high reliability and can strengthen the flexibility for extension of the system function.

Description

technical field [0001] The invention belongs to the field of automotive electronics, in particular to a general-purpose module used in a vehicle-mounted network and information integrated control system. Background technique [0002] With the improvement of people's requirements for the power, safety and comfort of passenger cars, the ECU (Electronic Control Unit, electronic control unit) and electronic control devices of passenger cars are also increasing. The traditional point-to-point communication method can no longer meet the distributed real-time control of automobiles. needs. The geometric growth of the number of wires due to the continuous increase of electronic equipment also makes it more and more difficult to wire in the limited space in the car, which limits the further expansion of the internal control function of the bus. On the other hand, the bus ECU is not simply connected to the load equipment, but more to exchange information with peripheral equipment and...

Problems solved by technology

The disadvantage of the above technologies is that the control modules in the vehicle network system have not been standardized and generalized, and the number of control modules is large, and the overall cost is high, which is not conducive to the popularization of the vehicle network technology.
