Intelligent alarm device of respirator

Abstract

The invention relates to an intelligent alarm device of a respirator. The intelligent alarm device mainly comprises a host machine, a high pressure sensor and a pressure switch, wherein the host machine is internally provided with a single chip microcomputer, a power supply, a button module, an omnibearing vibration sensor, a temperature sensor, an alarm and a liquid crystal display; a high pressure sensor signal circuit, a button module circuit, an alarm drive circuit, a liquid crystal display drive circuit and power circuits are respectively and electrically connected with the single chip microcomputer; and the power circuits comprise a power management control circuit and a power voltage sampling circuit. The intelligent alarm device can display pressure of a cylinder, remaining time of the cylinder and an ambient temperature, and can prompt and alarm when the cylinder is closed by accident. Meanwhile, the intelligent alarm device of the respirator has the functions of self detection and call for help. When accidents occurs, a person to be rescued can call for help by using a manual call-for-help button, and when the person unconscious can not evacuate by himself, an automatic call-for-help program is automatically started to notify workers nearby to rescue immediately.

Description

technical field [0001] The invention belongs to the electronic alarm technology, and in particular relates to an intelligent alarm device for a respirator. Background technique [0002] At present, in the domestic market, respirators basically use mechanical alarm devices, which usually only have a simple residual pressure alarm function, and do not have the function of displaying the remaining use time, ambient temperature and other system status, and consume part of the oxygen when alarming . When the rescuers are in a tense rescue, they cannot intuitively recognize the time for the remaining gas to breathe, which is very unfavorable for the rescuers to effectively evacuate the accident scene in the dangerous area. Therefore, for the respirator used by rescuers at the scene of an accident in a dangerous area, there is an urgent need for a respirator intelligent alarm device. Contents of the invention [0003] The purpose of the present invention is to provide an intell...
