The heating device 55 includes a resistance wire. The wire converts electrical energy into heat energy, which is transferred to the thermosphere, which ruptures as the temperature rises.

The temperature sensing bulb adopts the non-ferrous organic solution used in conventional firefighting, and the expansion coefficient is implemented in accordance with national standards, which will not be repeated here. Controls the power on or off of the heating wire. The nickel-chromium alloy grade Cr20Ni80 resistance wire has a rated power of 1000W, a resistance of 48 ohms, a specific heat capacity of 0.45-0.46J/kg.c, and a wire length of 100mm.

It can be edited and written in the device, but the storage capacity of basic status data in STM32 is small, only the most recent 2-3 sets of data can be stored, and functions such as fire big data analysis, remote reminder, alarm and control cannot be realized. Therefore, Another function of the wireless transmission unit 1 4 and the wireless transmission unit 2 54 is to send these data to a designated server for storage, and the corresponding storage capacity of these status data can be infinitely superimposed, and the STM32 Even if it is damaged, the previous data can still be preserved. Further, through the intermediate transfer of the server, the communication between the server and the user can be realized, and it is further realized that the user can operate on the mobile phone and the computer, and the corresponding server generates the corresponding instruction according to the user's operation and sends it to the user. Fire detectors and automatic sprinkler equipment; the computer software technology has been applied to many aspects such as daily social interaction, life, service, shopping, etc., so it will not be explained and repeated here.

Further, the water outlet direction and pattern control sheet is a metal sheet with a fixed pattern connected to the water outlet of the valve 53 through the screw principle. Specified style spraying, including direct flow in any direction and shower in any direction, can be directly installed at one end of the water outlet of the fire pipeline by casting the metal into the described metal sheet. The water outlet direction and style control sheet can be understood as some metal fittings with the same function, performance and style of sprinkler heads installed on traditional sprinkler heads.

Further, in the daily state, the integrated detection module 3 of the main control module 1 and the processor 51 in the pipeline control module 5 will pass the wireless transmission unit 1 4 and the wireless transmission unit 2 54 at a frequency of 30min/time. The state of each detector or device and the current current and voltage values are directly converted through the connection state of the STM32 pins and sent to the system. If the system does not receive the control module 5 uploaded data, the system will actively issue a status prompt instruction to the comprehensive detection module 3 of the main control module 1 and the pipeline control module 5. If the comprehensive detection module 3 of the main control module 1 and the pipeline control module 5 5. The instruction is immediately fed back and the status data is re-uploaded, which means that the data packet is lost in the data transmission process, but the comprehensive detection module 3 of the main control module 1 and the pipeline control module 5 are in normal working state; if received In the instruction, if the data sent by any one or more of the smoke detection unit, flame detection unit 11, infrared temperature measurement unit 61, valve 53 and other sensors are displayed as 0 or null bytes, it represents the smoke detection unit, flame Any one or more of the sensors such as the detection unit 11, the infrared temperature measurement unit 61, and the valve 53 are in a component failure state, and the management personnel are reminded to check on the site to see if there is any obstruction by foreign objects. If the components are damaged, the equipment needs to be replaced; further, if the displayed values of voltage and current are low, it means that the voltage is disconnected and the battery power is low, and management personnel need to inspect the power supply circuit or replace the battery; further, If the battery power is not enough for the device to start, the corresponding NB-Lot module stops working completely, disconnects from the system completely, can neither send information nor receive the status command issued by the background, then it can be further judged as NB Module failure or low battery.
