Vehicle-mounted power supply system of communication equipment

Abstract

The invention discloses a vehicle-mounted power supply system of communication equipment. The vehicle-mounted power supply system comprises a communication equipment power supply storage battery, a power distribution control unit and a wireless backpack device. Wherein the power distribution control unit is electrically connected to the communication equipment power supply storage battery and is used for adjusting the output voltage of the communication equipment power supply storage battery and supplying power to the wireless backpack device; an equipment box where the power distribution control unit is located is provided with a first fan capable of automatically operating so as to carry out air-cooling heat dissipation on the internal space of the equipment box; the wireless backpack device comprises a backpack battery, when the wireless backpack device is in a vehicle-mounted state, the power distribution control unit supplies power to the wireless backpack device and charges the backpack battery, and when the wireless backpack device is in a backpack state, the wireless backpack device works under the power supply of the backpack battery; and the wireless backpack device automatically dissipates heat and heats the backpack battery through a second fan and a battery heating device which can automatically operate. According to the system, the use requirement that the communication equipment is loaded from a vehicle-mounted state to a back-mounted state under the condition of uninterrupted power supply and uninterrupted working state in a large-span temperature environment is met.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a vehicle-mounted power supply system for communication equipment. Background technique [0002] In the vehicle-on-board application scheme of communication equipment, how to provide power supply is a very important issue. At present, the power supply methods of vehicle communication equipment are usually powered by the vehicle's own starter battery, external battery, external generator or external AC and DC power supply. Among them, the power supply depends on the total power of the communication equipment. For scenarios with low power supply and high mobility requirements, the vehicle-mounted power supply method is mainly used, but the vehicle-mounted power supply method cannot ensure continuity, and further energy storage batteries are needed. At present, the types of energy storage batteries that can be used include lead-acid batteries, lead-acid maintenance-free batter...
