Referring to fig. 6, the control principle of the intelligent long tube air-supply filtering respirator of the present invention is as follows: the host control circuit consists of an ARM microprocessor, a Bluetooth module, a 4G communication module, a motor driving circuit, a gas transmitter module, an audible and visual alarm circuit, a 433M voice communication module, an OLED display module and a power management circuit. The power supply mode adopts two modes of alternating current 220V commercial power supply and lithium battery power supply.

The specific implementation mode is as follows: the host computer inserts the power cord, opens main switch, presses start button, and power indicator lights, starts the back, and the host computer gets into trouble self-checking mode, and equipment detects the abnormal entering monitoring mode that does not have after 5 seconds. The display screen displays in real time: working voltage, environment temperature, power supply working mode, residual service life, air supply quantity value, 4G signal intensity, toxic gas and combustible gas alarm information, interphone connection state and the like. After confirming that no abnormity exists, tying the waistband at a proper position between the waists, after the tightness is properly adjusted, well inserting one end of the long air supply pipe into the host machine, and well inserting the other end of the long air supply pipe into the inlet of the flow adjusting valve; one end of the air supply short pipe is well inserted with the outlet of the flow regulating valve, and the other end of the air supply short pipe is well inserted with the breathing mask. Before connection, whether the communication cable in the air supply pipe is firmly connected or not needs to be confirmed.

Selecting an air supply gear according to the length of the air supply pipe: 1 st gear (30 m), 2 nd gear (40 m) and 3 rd gear (50 m). The specific implementation is as follows: when the communication mask is worn, the corresponding air supply opening switch can be started by pressing for 1 second, and at the moment, the air supply opening working indicator lamp is turned on to supply air to the communication mask by using the air supply value of 130L/min +/-5%. The initial loading state is 1 grade, and the air supply pipe is suitable for being used under the length of 30 meters. If the 2 nd gear and the 3 rd gear need to be adjusted for use, the corresponding air supply opening switch needs to be pressed for more than 3 seconds for switching (can be switched circularly).

In order to ensure no abnormity of communication, the breathing surface is required to be tested. The specific implementation is as follows: the breathing mask needs to be provided with 2 pieces of No. 7 alkaline batteries, a long-key breathing mask power switch is turned on for more than 2 seconds, three sounds of 'ticking' are heard to represent that the electric quantity is sufficient, and if only one sound of 'dropping' is heard, the batteries need to be replaced when the electric quantity of the meter is insufficient. If the "tic" occurs every 10 seconds during use, the battery needs to be replaced by returning to the ground as soon as possible.

The breathing mask is internally integrated with a microphone, so that the sound amplification communication and the remote communication can be realized. And when the user directly speaks, the amplified communication can be realized. The implementation mode when the intercom communication is needed is as follows: the main machine turns on the talkback channel switch to keep the channel consistent with other talkbacks, the volume of the conversation is properly adjusted, the breathing mask is integrated with a PTT talkback key, when the PTT key is pressed and not loosened, the remote communication can be realized, the talkback key is loosened after the conversation is finished, and then the mode is automatically switched to the sound amplification mode. At this time, the voice signal is connected with the host computer outside the field through the communication cable, and the host computer sends out the talkback signal. If the frequency of the interphone is the same as that of the intelligent host, the interphone communication can be normally realized. If the talkback signal is expected to be transmitted farther (> 3.5 Km), the public network talkback needs to be started. The public network talkback implementation mode is as follows: the public network talkback switch is turned on, the indicator light periodically flickers with the red and green color of 0.5 second during initialization, and the indicator light is turned into the normally-on green light when the 4G network is successfully connected. The signal intensity of the OLED display screen can be observed so as to monitor the quality of the communication information. (4G public network intercommunication requires interphone to support the function)

The host computer is reserved with a 4G communication interface, an interface protocol accords with the LTE technical standard, supports the 4G-LTE transparent transmission technology and supports four protocols of HTTP \ UDP \ MQTT \ TCP, and when information is required to be transmitted to a rear monitoring command platform, seamless butt joint can be carried out only by providing a server IP address.

The main machine is provided with 1 exhaust channel for exhausting residual inflammable gas in the operation space and preventing spark explosion in the operation process. The air exhaust channel is controlled by a switch and is opened/closed according to actual requirements.

The host computer is provided with a 6-in-1 toxic gas detection module which can simultaneously detect the concentrations of carbon monoxide, oxygen, hydrogen, carbon dioxide, combustible gas and hydrogen sulfide gas. The sensors can be freely matched and used according to different use environments, the sensors can be automatically replaced after the service life of the sensors is over, and the sensors are convenient to maintain. When the detected gas concentration exceeds the set threshold value, the host machine is triggered to sound for alarm, the alarm lamp of the breathing mask flashes at the same time, the use environment is proved to be dangerous, and the talkback key of the breathing mask can be pressed to actively talk back to request support with an off-site monitoring person. If the 4G public network transmission is opened and the networking communication with the fire command monitoring center of the emergency management department is successful, the monitoring data can be returned in real time, and once an emergency accident happens, the operation scheme of police force transfer, cooperative operation, rapid deployment and rapid support can be rapidly realized according to the size of the field accident.
