The top of fire extinguisher bottle 1 is fixedly installed with handle 3, and the side of handle 3 is fixedly installed with nozzle 4.

[0026] In the embodiment, pressure monitoring module 27 selects SPT series high-precision pressure sensor of Honeywell, SPT3000 model. The sensor accuracy can reach ±0.1%FS, and the internal pressure of fire extinguisher can be accurately measured. Its measurement range can be customized according to the common fire extinguisher pressure range, such as 0-6MPa, which can meet the pressure monitoring needs of different types of fire extinguishers. The sensor and fire extinguisher bottle 1 are sealed by sealing glue to ensure the sealing effect and ensure that the pressure sensor can collect fire extinguisher internal pressure data in real time. When the pressure exceeds the preset normal range, the abnormal signal is sent to the control module through the SPI interface immediately;

[0027] The position monitoring module 23 adopts a NEO-M8N GPS positioning chip of u-blox company, the positioning accuracy of which can reach 2.5 meters CEP, and can accurately and real-timely position the geographic position of the fire extinguisher.

The management terminal can be a computer, a mobile phone or the like, and the management personnel can receive information and perform management operation through the corresponding APP or software

[0031] The power module 26 provides power support for the entire device, and the power module 26 adopts a 18650 rechargeable lithium battery.

[0032] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0033] Working principle: In the intelligent fire extinguisher monitoring device, the pressure monitoring module 27 is connected to the inside of the fire extinguisher bottle 1 through a sealing glue, and the internal pressure of the fire extinguisher is monitored in real time. Once the pressure deviates from the preset normal range, an abnormal signal is sent to the control module through the SPI interface, the position monitoring module 23 tracks the geographic position of the fire extinguisher at all times, and when the fire extinguisher moves a distance exceeding the 2-meter set threshold, a position change signal is sent to the control module through the UART interface. The temperature monitoring module 24 uses the MF52 series NTC thermistor to form a voltage dividing circuit with a precision resistor, converts the temperature change into a voltage change input to the control module ADC pin, and quickly transmits a high temperature signal when the temperature exceeds the safety upper limit of 60°C. The control module uses an STM32F407 microcontroller to receive data from the pressure monitoring module 27, the position monitoring module 23, and the temperature monitoring module 24, analyze and judge the working state of the fire extinguisher, and if abnormal, send an alarm message to the management terminal through the wireless communication module via the UART interface. The power module 26 uses a 18650 rechargeable lithium battery to provide stable power supply for each module and ensure continuous operation of the device.
