Intelligent monitoring terminal for vehicle power supply system

Abstract

The invention provides an intelligent monitoring terminal of a vehicle-mounted power supply system. The intelligent monitoring terminal comprises a processor, a power supply input interface, a power supplying power supply, n power supply paths and n power supply output interfaces, wherein the output end of the power supplying power supply is connected to the corresponding power supply output interface through the corresponding power supply path; each power supply path is respectively connected with a current sensor and a relay control switch in series; the current sensor is connected to the input end of the processor through an AD (analog-to-digital) converter; the output end of the processor is connected to a relay control switch through a relay driving circuit. The intelligent monitoring terminal has the advantages that the power supply condition of various kinds of electronic equipment can be monitored in real time; when the condition that a power supply path fails is monitored, the power supply path of the electronic equipment with the fault is cut off in time; the danger of the vehicle-mounted power supply system due to the self fault of the external electronic equipment per se is prevented; the power supply safety of the electronic equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to an intelligent monitoring terminal of a vehicle power supply system. Background technique [0002] The intelligence level of the transportation industry is increasing day by day, and there are more and more electronic devices in the bus, such as DVR, LED screen, LCD indicator, station sign, passenger flow counter, etc., all of which rely on the power bus in the car powered by. [0003] However, in the process of realizing the present invention, the inventors found that the prior art has at least the following problems: [0004] When the power bus in the car supplies power to each electronic device, when the electronic device has a fault such as a short circuit, it is easy to cause the power supply of the car body to fail, and in severe cases, it may even cause a short circuit of the power supply of the car body itself, a fire and other major danger...
