Intelligent power supply box for supplying electricity for vehicle-mounted precision equipment

Abstract

The invention discloses an intelligent power supply box for supplying electricity for vehicle-mounted precision equipment. The intelligent power supply box for supplying electricity for vehicle-mounted precision equipment comprises a box body; the box body is provided with a control panel; the control panel is provided with a display control panel, a switch amount detection module, a display screen, a power supply module, an alternating-current input interface, a direct-current input interface and a plurality of output interfaces; the box body is internally provided with an input module, an AC / DC (alternating-current) / (direct-current) rectification voltage stabilizing module, a DC / DC voltage reduction module, a DC / DC voltage stabilizing module, a DC / AC inversion module, a plurality of power modules and an electricity distribution control module. According to the invention, 24V storage batteries and 220V electric supplies for vehicles can be connected, AC220V, DC12V and DC24V electricity supplying power supplies can be provided for electricity using equipment on the vehicles, and the intelligent power supply box for supplying electricity for vehicle-mounted precision equipment has the protection functions of excessive current, excessive voltage, short circuit and the like, controls the electricity supplying for the electricity using equipment though a control platform, and monitors the input power supply parameters, equipment working states and fault.

Description

technical field [0001] The invention relates to the field of power supply for vehicle-mounted equipment, in particular to an intelligent power supply box for powering vehicle-mounted precision equipment. Background technique [0002] With the development of electronic technology, the weight and volume of various instruments and equipment have been greatly reduced. For some precision equipment (such as monitors, ventilators and other medical equipment) that require mobile applications, they can be easily installed on the car. Carization. At present, the power supply of the on-board precision equipment on the usual ambulance basically uses the 24V DC output of the on-board battery. There are two main problems in using this power supply method: one is that the 24V voltage output by the battery on the car has relatively large fluctuations, which can reach 29V when it is high, and only 20V when it is low; powered by. Moreover, this power supply method does not provide protecti...
