Power supply management method of operating room equipment, power supply system, operating lamp and operating bed

Abstract

The invention provides a power supply management method of operating room equipment, a power supply system, an operating lamp and an operating bed. The method is used for providing a power supply system for operating room equipment. The power supply system comprises a main power supply, a standby power supply and a main-standby switching circuit. The method comprises the steps of detecting a levelsignal of the main power supply; according to the change of the level signal of the main power supply, the main-standby switching circuit is driven, so that the standby power supply supplies power tothe driving equipment of the operating bed assembly or the power supply equipment in the operating lamp assembly after boosting, or the main power supply supplies power to the driving equipment of the operating bed assembly or the power supply equipment in the operating lamp assembly. According to the scheme, the main and standby switching circuit completes rapid switching of the main and standbypower supplies by detecting the detection result of the level signal of the main power supply, the problem of unstable power supply caused by voltage drop in the switching process is avoided, and thepurpose of stably supplying power to a rear-end load in the main and standby power supply switching process is achieved.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a power supply management method for equipment in an operating room, a power supply system, an operating lamp and an operating bed. Background technique [0002] During the operation, a separate set of main and backup power supply systems are used for the power supply of loads such as operating lights and operating beds. [0003] At present, in the existing technical solutions of main and backup power supply systems, the switching between main and backup power mainly relies on active switching tubes to control the switching between the main and backup power supplies. However, on the one hand, because the active switching tube is on-load switching, the current and voltage stress are very large, causing the active switching tube to be easily damaged and affecting the power supply to the back-end load; on the other hand, due to the hysteresis of the active control signal The...

Problems solved by technology

However, on the one hand, because the active switching tube is on-load switching, the current and voltage stress are very large, causing the active switching tube to be easily damaged and affecting the power supply to the back-end load; on the other hand, due to the hysteresis of the active control signal The problem caused by the main and standby power supply switching process, the output voltage will have a large drop, which may lead to abnormal power supply to the back-end load

[0004] It can be seen from this that the main-standby power supply system of the prior art is used to switch the main-standby power supply to supply power to the back-end load, which will lead to unstable power supply and abnormal power supply.
