Pressure sensor is arranged above and below filter screen respectively, and the pressure difference of both sides of filter screen is detected through two pressure sensors. When filter screen is blocked, the pressure difference of both sides of filter screen will increase, and the pressure difference signal detected by pressure sensor is transmitted to control module. Smoke detection module, pressure sensor 3, control module and communication module are electrically connected through circuit.
[0019] Please refer to Figure 1The filter screen is located on one side of the air suction pipeline close to the air inlet, and the top and bottom of the filter screen are provided with pressure sensors. The smoke detection module is provided with a photoelectric sensor and a laser sensor, and the photoelectric sensor and the laser sensor are electrically connected with the control module. The sensor performance monitoring system: the smoke detection module adopts an advanced photoelectric sensor or a laser sensor, and the sensor is electrically connected with the control module. The control module regularly sends a detection instruction to the sensor, and the sensor performs self-detection after receiving the instruction, and feeds back the detected performance parameters of the sensor, such as sensitivity and response time, to the control module.

The shell of the detector shell is provided with an indicator light, and the indicator light is electrically connected with the smoke detection module, the pressure sensor, the control module and the communication module through wires.
[0020] It should be noted that the utility model is a kind of suction type smoke detector with intelligent maintenance reminding function, including 1, main control board;2, filter;3, pressure sensor;4, detector, components are general standard parts or components known to those skilled in the art, its structure and principle are all known to the technical personnel by technical manual or by conventional experimental method.
[0021] The working principle of the utility model is: firstly, equipment installation is carried out, the air suction type smoke detector is installed in the place needing fire early warning, it is ensured that there is no obstacle around the air inlet on the detector shell, air can be inhaled normally. The air suction pipeline is connected with the air inlet and the air suction pump correctly, it is ensured that the pipeline is sealed well, there is no air leakage phenomenon. The circuit between the smoke detection module, the pressure sensor, the control module and the communication module is connected well, it is ensured that the modules can communicate and data transmit normally. In working, normal monitoring state: after the equipment is powered on and started, the air suction pump starts to work, the external air is sucked into the detector through the air suction pipeline. The smoke detection module detects the smoke concentration in the inhaled air in real time, and transmits the detected smoke concentration signal to the control module. At the same time, the pressure sensor located on both sides of the filter screen detects the pressure difference on both sides of the filter screen in real time, and transmits the pressure difference signal to the control module. The control module sends detection instructions to the sensor in the smoke detection module regularly, and the sensor feeds back the performance parameters to the control module after self-detection. When the filter screen is blocked due to dust accumulation and other reasons, the pressure difference on both sides of the filter screen increases when the maintenance reminding trigger is triggered. When the pressure difference exceeds the preset alarm threshold in the control module, the control module determines that the filter screen needs to be cleaned or replaced, and immediately starts the communication module, sends the filter screen blocking reminding information to the terminal equipment of the management personnel, and the indicator light on the detector shell flashes. When the performance parameters of the sensor in the smoke detection module deviate from the preset normal range, the control module also determines that the sensor needs to be maintained, sends the sensor fault reminding information through the communication module, and triggers the indicator light to flash. In addition, the control module also sends the preventive maintenance reminding information in advance according to the use time of the equipment and the preset maintenance period, such as reminding to clean the filter screen regularly, calibrate the sensor, etc. When the maintenance operation is carried out, the management personnel can arrange the maintenance personnel to carry out the corresponding maintenance operation according to the reminding content after receiving the maintenance reminding information. For the filter screen blocking problem, the maintenance personnel can open the detector shell, take out the filter screen and clean or replace it. For the sensor performance abnormal problem, the maintenance personnel can calibrate or replace the new sensor using professional tools. After the maintenance is completed, the equipment reenters the normal monitoring state, the control module records the maintenance operation information, and updates the maintenance record of the equipment.
