Fire-fighting intelligent switch power supply

Abstract

The invention discloses a fire-fighting intelligent switch power supply, which comprises a communication interface circuit, a master control circuit, a voltage collection circuit, a voltage output circuit, a switching circuit, a charging circuit, a storage battery and a transformer circuit, wherein the transformer circuit is connected with a commercial power source. Through a reasonable circuit structure and control mode design, circulating charging and discharging of the storage battery are achieved while normal work of a fire alarm controller is maintained; the storage battery is well maintained; and the normal service lifetime of the storage battery is effectively maintained. Therefore, the fire-fighting intelligent switch power supply is suitable for popularization and application.

Description

technical field [0001] The invention relates to a power supply, in particular to a fire-fighting intelligent switching power supply. Background technique [0002] At present, many public places have installed automatic fire alarm systems for emergency calls when a fire breaks out. Generally speaking, the fire alarm controller in the automatic fire alarm system will be equipped with a battery. According to the functional characteristics of the battery, precautions for use and maintenance requirements, the battery must be charged and discharged once within a certain period of time to ensure the normal service life of the battery. . Under normal power supply status, the operator will not manually discharge the battery. [0003] However, the mains switching power supply in the existing fire alarm controller does not have the function of automatically switching the power supply equipment. Usually, the battery of the fire alarm controller will be in a floating charge state for a...

[0003] However, the mains switching power supply in the existing fire alarm controller does not have the function of automatically switching the power supply equipment. Usually, the battery of the fire alarm controller will be in a floating charge state for a long time, and only when the power is cut off, it is manually switched. The battery will not be in the discharge state until the battery is working

In a short period of time, such an operation method will not have any impact, but in the long run, it will seriously affect the service life of the battery, and often the battery will lose its power storage capacity before the service life of the battery

[0004] In addition, when the mains power supply or battery discharge power supply is used, the existing method still has the situation that the working status information, voltage parameters and power information of the mains power supply and the battery cannot be exchanged with external devices in time, resulting in on-site The on-duty personnel cannot judge the working status of the current mains power supply or storage power supply through the real-time data of the voltage, and then take effective measures for emergencies
