The invention relates to an embedded management system for power supply of on-vehicle equipment. An MAC interface of a central processing unit is bidirectionally connected with an Ethernet module. A power interface management module comprises a power interface circuit. A power supply port of the power interface circuit is connected with the input end of the central processing unit. Each equipment interface management module comprises an overcurrent detecting circuit, a power supply control circuit and an equipment interface circuit. The overcurrent detecting circuit is arranged in the power supply circuit of each equipment interface management module and acquires circuit current condition through a current sensor which is arranged in the circuit. The output end of the overcurrent detecting circuit is connected with the master control port of the power supply control circuit. The output end of the power supply control circuit is connected with the input end of the equipment interface circuit. The output end of the central processing unit is connected with the master control port of the power supply control circuit. The embedded management system is used as a unified centralized power supply platform of the on-vehicle electronic equipment and has an advantage of centralized and safe power supplying for electronic equipment mounted in a vehicle.
Description
technical field [0001] The invention relates to the field of vehicle control, in particular to an embedded management system for power supply of vehicle equipment. Background technique [0002] There are many types of on-board electronic equipment on existing public transport vehicles, in addition to pre-installed electronic equipment to ensure the operation of the vehicle itself, such as vehicle power systems, control systems, lighting systems, etc.; limited by the structure of the vehicle itself and the electrical characteristics of the electrical equipment , The power supply lines of various electronic devices vary in thickness and length, and basically spread all over the vehicle. These electronic devices, especially for various after-installed application systems, are independently powered from the main power supply inside the vehicle, and lack unified power supply monitoring and management. [0003] At present, the centralized and safe power supply of electronic equip...
