Remotely controllable power distribution control circuit

Abstract

The invention relates to a remotely controllable power distribution control circuit. The power distribution control circuit comprises a central processing unit MCU, a CAN bus circuit, a digital signal acquisition circuit, an intelligent high side switch circuit, a temperature acquisition circuit and an electromagnetic switch, wherein the CAN bus circuit, the digital signal acquisition circuit, the intelligent high side switch circuit, and the temperature acquisition circuit are connected with the central processing unit MCU, and the electromagnetic switch is respectively connected with the temperature acquisition circuit and the intelligent high side switch circuit. The digital signal acquisition circuit transmits the collected digital signal to the central processing unit MCU, and the central processor MCU determines the validity of the digital signal; the CAN bus circuit is connected to the central processor MCU and a vehicle-mounted driving computer, and the central processor MCU receives and transfers vehicle information through the digital signal acquisition circuit and the CAN bus circuit; the temperature acquisition circuit acquires and monitors the temperature of the electromagnetic switch and transmits to the driving computer through the CAN bus circuit.

Description

technical field [0001] The invention belongs to the technical field of power distribution control for vehicles, in particular to a power distribution control circuit capable of remote monitoring. Background technique [0002] In order to cope with and solve the limitations and bottlenecks brought by the shortage of fossil energy to the automobile industry, the research and development of new energy vehicles using new energy as the power source has always been a new hot spot. New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, or use conventional vehicle fuels and adopt new vehicle power devices. New energy vehicles use less and no fossil fuels, reducing dependence on fossil fuels sex. The current new energy vehicles include gas vehicles (liquefied natural gas, compressed natural gas), fuel cell electric vehicles, pure electric vehicles, liquefied petroleum gas vehicles, hydrogen energy vehicles, hybrid vehicles (oil-gas hybrid, oil-...

Problems solved by technology

[0003] The power supply control is an important part of the vehicle. The power supply to the electrical components on the vehicle is mainly low-voltage power supply. However, most of the existing low-voltage controls move the control circuit of the traditional car, which is likely to cause safety hazards and accidents during use.
