Embodiment Construction

[0030] Such as figure 1 , Is a schematic diagram of the installation of the air respirator condition monitoring device implemented in the present invention. In the present invention, a three-way valve 1 is installed between the pressure gauge 12 and the pressure reducing valve 15 of the positive-pressure air respirator, and the third end of the three-way valve 1 is connected to the intelligent monitoring module 3 through the pressure measuring tube 2. The three-way valve 1 is installed at the air interface that was originally connected to the pressure gauge 12, which can directly pass high-pressure gas to the pressure gauge 12, maintaining the original pressure measurement function; the three-way valve 1 simultaneously transmits the high-pressure gas to the pressure measurement tube through the other end 2. The pressure measuring tube 2 is in the form of a hose, which can connect the gas with the intelligent monitoring module 3.

Abstract

The invention provides an intelligent monitoring device and method for the air respirator state. The intelligent monitoring device is composed of a central control unit, a power supply unit, a pressure sensor unit, a switch control unit, a liquid crystal display unit, an indicator lamp unit and a vibration prompting unit. The central control unit is the core of the whole intelligent monitoring device and is connected with the switch control unit, the pressure sensor unit, the liquid crystal display unit, the indicator lamp unit and the vibration prompting unit. The central control unit, the switch control unit, the pressure sensor unit, the liquid crystal display unit, the indicator lamp unit and the vibration prompting unit are installed on the same circuit board as a whole. The power supply unit is connected with the units through power supply lines. The intelligent monitoring method for the air respirator state includes two steps. The monitoring device can be aligned with an air respirator to conduct real-time monitoring and alarming on the current air pressure and can estimate the available remaining time according to the estimation method, the digitalized display method is adopted for the intelligent monitoring device, reading is convenient, and the vibration alarming can be provided when the remaining air amount is smaller than 5 Mpa.

Description

Technical field [0001] The invention belongs to the field of state monitoring of emergency rescue equipment, and relates to an intelligent monitoring device and method for the state of an air respirator. Background technique [0002] With the gradual increase of potential safety hazards such as chemical accidents and fires, positive pressure air breathing apparatuses are increasingly being equipped in military professional rescue teams, firefighting forces and various professional rescue forces. At the same time, it is also used in some professional workplaces. Indispensable labor protection equipment. The air respirator has a simple structure and can provide air at a certain pressure for rescuers on special occasions. However, the current domestic inspection of positive pressure air respirators generally uses external equipment or simple trial methods for air tightness and fault detection before use At the same time, some of the methods for the air volume alarm of the air respi...
