Method and device for controlling working state of air-pressure warning device

Abstract

The invention is applicable to emergency equipment and provides a method and device for controlling the working state of an air-pressure warning device. The method comprises the steps that when the air-pressure warning device is in the sleep mode, if a working signal sent by a matched air-pressure monitoring device is detected, the air-pressure warning device is switched from the sleep mode to the normal working mode; and when the air-pressure warning device is in the normal working mode, if the working signal sent by the matched air-pressure monitoring device is not detected within first preset time length, the air-pressure warning device is switched from the normal working mode to the sleep mode. According to the method and device for controlling the working state of the air-pressure warning device, intelligent switching between the sleep mode and the normal working mode is conducted on the air-pressure warning device according to the working condition of the air-pressure monitoring device, and the effect of saving energy and electricity is achieved; battery replacement frequency is reduced; equipment application cost and maintenance cost are greatly lowered; and meanwhile, equipment can be more intelligentized.

Description

technical field [0001] The invention belongs to emergency equipment, in particular to a method and device for controlling the working state of an air pressure warning device. Background technique [0002] Air respirators are common emergency equipment, such as air respirators, which are self-contained open air respirators, also known as air storage gas masks, sometimes called fire masks, which use compressed gas cylinders as the gas source, but The gas contained in the cylinder is compressed air. Air respirators are widely used in fire protection, chemical industry, shipbuilding, petroleum, smelting, warehouses, laboratories, mines and other departments, for firefighters or emergency rescue personnel to breathe safely and effectively in various environments such as dense smoke, poisonous gas, steam or lack of oxygen. Carry out fire fighting, emergency relief and ambulance work. [0003] In the air respirator, for the convenience of the user, the air supply device, that is,...

AI Technical Summary

Problems solved by technology

At present, the air pressure warning device needs to receive the working signal sent by the air pressure monitoring device, but the air pressure monitoring device can only be manually closed by the user, and the user often forgets to close it when using it, and there is often an idle period when the device is not used At this time, although the air pressure monitoring device does not send a working signal, the air pressure warning device is still in the activated state

[0005] Therefore, the current working method of the air pressure warning device consumes a lot of power and consumes power quickly, and the battery needs to be replaced frequently, which greatly increases the use and maintenance costs of the equipment.
