The detection unit 3 can be detachably set on the ceiling of the kitchen through a mounting bracket, and the processing unit 4 is used to perform fire extinguishing operations or fire prevention operations.

[0046] Specifically, this fire prevention and control system is mainly used in the kitchen. The detection unit 3 monitors the environmental conditions in the kitchen in real time, including temperature, smoke concentration, etc., and sends the detected data to the signal analysis unit 5. After calculation and analysis by the signal analysis unit 5, the processing unit 4 is started to perform corresponding fire prevention or fire extinguishing treatment when an abnormality is determined, thereby achieving the goal of kitchen fire prevention and fire extinguishing. Among them, the detection unit 3 is set on the ceiling of the kitchen, which is in line with the rising trend of high-temperature smoke and heat, and can detect environmental abnormalities in time. Moreover, it can be detachably set on the ceiling through a mounting bracket, which is convenient for disassembly and assembly, and is convenient for adjusting the layout position, thereby increasing detection sensitivity.

[0048] Specifically, in a kitchen where the ceiling is made of suspended ceiling panels 1, the panel size of the suspended ceiling panels 1 is 300mm*300mm, and the mounting platform is a mounting panel 2 that is adapted to the size of the suspended ceiling panels 1, also 300mm*300mm. The mounting panel 2 is directly fastened between the suspended ceiling panels 1, which is convenient for adding, removing, or adjusting the position in the kitchen. At the same time, the appearance is more coordinated and not abrupt, and does not affect the aesthetics. The smoke sensor 31 is used to detect the smoke concentration, the temperature sensor 32 is used to detect the temperature, and the human body sensing component 34 is used to detect whether there is human activity in the kitchen, and send the signal to the signal analysis unit 5. The signal analysis unit 5 combines the data provided by the detection unit 3 to comprehensively judge whether it is a normal kitchen operation, thereby improving the accuracy of fire prevention and control. The detection unit 3 is hidden on the back of the mounting panel 2 and does not affect the aesthetics. The detection end extends from the detection hole 21, ensuring the accuracy and sensitivity of the detection.

[0049] As an optimization of this embodiment, an annular sealing ring is provided between the detection hole 21 and the inner end of the detection end.

[0051] Specifically, processing unit 4 is also equipped with a fire extinguishing assembly 41. This extinguishing assembly is implemented using a water-based fire extinguishing device and is suitable for extinguishing fires of flammable materials. Its switch is in communication with signal analysis unit 5 and can be immediately activated when signal analysis unit 5 detects an abnormality, quickly extinguishing the fire. A power-off switch assembly 44 is used to cut off the power supply to kitchen appliances in the event of an abnormality, resolving the source of fires caused by electrical short circuits. Timely power outages also make firefighting safer. A gas shut-off valve assembly 45 is used to cut off the gas supply to prevent gas output from increasing the fire or even causing an explosion. An alarm assembly 46 is used to sound a buzzer alarm to promptly alert nearby personnel to the presence of an abnormality.

The detection unit 3 and the signal analysis unit 5 are connected in communication, and the processing unit 4 and the signal analysis unit 5 are electrically connected to transmit detection data and process signals. The line connection has the characteristic of good stability.

[0053] Specific working principle: When working, the temperature sensor 32 and the smoke sensor 31 monitor the environmental parameters in the kitchen in real time, and transmit the environmental data to the signal analysis unit 5. The signal analysis unit 5 analyzes and calculates according to the corresponding set logic. When it concludes that it is abnormal, it immediately sends a processing signal to the detection unit 3, that is, controls the water-based fire extinguishing equipment, the power-off switch assembly 44, the gas-off valve assembly 45 and the buzzer to start, cuts off the power and gas, emits a buzzer alarm and outputs the fire extinguishing agent to extinguish the fire.

[0060] Specifically, the signal processing module 55 receives environmental data from the detection unit 3 and, based on relevant analysis logic, calculates whether an anomaly exists. If an anomaly exists, it promptly sends a processing signal to the processing unit 4, enabling rapid intervention. The internet connection module 51 transmits environmental data and the operating status of relevant equipment to the internet. Corresponding control and prevention software 52 is developed online and integrates relevant data, enabling managers to obtain timely and comprehensive information about the situation. Control and prevention software 52 can also send control signals to the signal analysis unit 5 to activate the corresponding processing unit 4. Furthermore, the signal processing module 55 communicates with the remote control 54 via the remote control signal receiving unit 53.

[0061] Specific working principle: When an abnormality is detected, the processing unit 4 is started. At the same time, the prevention and control software 52 reminds the corresponding abnormal situation and displays the current environmental data and the working status of each unit. The user can call 119 for help with one click according to the actual situation. When it needs to be shut down, a shutdown signal can also be sent to reset and shut down the water-based fire extinguishing equipment, the power-off switch assembly 44, the gas valve assembly 45 and the buzzer.

[0062] Example 4

[0063] The specific working principle of this embodiment is basically the same as that of embodiment 1, and the difference lies in the fire extinguishing component 41.

[0064] Specific implementation examples Figure 5As shown, the water-based fire extinguishing device's switch is connected to the signal analysis unit 5 via a wireless module 43. The fire extinguishing assembly 41 is equipped with an active start / stop switch 47, which is electrically connected to the household power supply. The fire extinguishing assembly 41 includes an independent power supply 42, which is electrically connected to the fire extinguishing assembly 41.

[0065] Specifically, processing unit 4 is also equipped with a fire extinguishing assembly 41. This extinguishing assembly 41 primarily utilizes water-based fire extinguishing equipment and is suitable for extinguishing fires of flammable materials. Its switch is communicatively connected to signal analysis unit 5, allowing it to be immediately activated when the signal analysis unit 5 detects an anomaly, quickly extinguishing the fire. Fire extinguishing assembly 41 is also equipped with an active start-stop switch 47. This allows the user to proactively activate fire extinguishing if detection unit 3 fails to detect an anomaly or if manual activation is required, enhancing practicality.
