[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figure 1, in the embodiment of the present utility model, a simple sprinkler fire extinguishing system includes: a detector group 1, a controller 2, and a simple sprinkler device 3 that are connected in sequence according to the signal transmission direction; the detector group 1 is used to detect various environmental data and transmit various environmental data and alarm information to the controller 2, and the detector group 1 includes a thermal imaging camera 11, a smoke detector 12, and a temperature detector 13; the thermal imaging camera 11 is connected to the controller 2 and is used to transmit temperature data and image data; the smoke detector 12 and the temperature detector 13 are connected to the controller 2 and are used to transmit smoke alarm information and temperature alarm information to the controller 2 respectively; the controller 2 is used to receive various environmental data and alarm information sent by the detector group 1 and to control the opening and closing of the simple sprinkler device 3; the simple sprinkler device 3 includes a pipe network 31, a solenoid valve 32, and a plurality of parallel open sprinkler heads 33 arranged on the pipe network 31 in sequence along the water flow direction; the controller 2 obtains an alarm instruction based on various environmental data and alarm information detected by the detector group 1, and uses the temperature data and image data of the thermal imaging camera 11 to judge the authenticity of the alarm instruction. If it is a real fire alarm, the controller 2 opens the solenoid valve 32 so that the water flow extinguishes the fire in the environment through the open sprinkler heads 33.

[0030] The controller 2 includes a main control module 21, a network interface module 22, an RS485 module 23, and a valve control module 24 that are respectively connected to the main control module 21. The main control module 21 is used to receive and process various environmental data and alarm information and to output a control signal; the network interface module 22 is connected to the thermal imaging camera 11 and is used to transmit the temperature data and image data of the thermal imaging camera 11 to the main control module 21; the RS485 module 23 is connected to the smoke detector 12 and the temperature detector 13 and is used to transmit the smoke alarm information and temperature alarm information of the smoke detector 12 and the temperature detector 13 to the main control module 21; the valve control module 24 is connected to the solenoid valve 32 and is used to transmit the opening and closing control signal output by the main control module 21 to the solenoid valve 32 to realize the conduction or truncation of the pipe network 31.

[0031] The specific alarm logic is as follows:

[0032] When the environmental data detected by the smoke detector 12 or the temperature detector 13 reaches the threshold value, an alarm information is sent to the controller 2. The threshold range of the ordinary smoke detector 12 is 0.1 - 5mg / m 3 , in this embodiment, 0.2mg / m is adopted 3; The RS485 module 23 transmits the alarm information sent by the smoke detector 12 or the temperature detector 13 to the main control module 21. When the main control module 21 receives the alarm information, it links the thermal imaging camera 11 through the network port module 22 to obtain the image data of the real environment and the temperature data in the image. If the temperature data reaches the set threshold, it is judged as a real fire alarm. At this time, the controller 2 controls the solenoid valve 32 to open, that is, the fire extinguishing system is turned on, so that water flows into the pipe network 31, and the water is finally sprayed into the environment from the open sprinkler head 33 to extinguish the fire; if the temperature data does not reach the set threshold, it is judged as a false fire alarm. At this time, the controller 2 will not send a signal to the solenoid valve 32 to keep the solenoid valve 32 closed, that is, the fire extinguishing system is not turned on.

[0033] The simple sprinkler fire extinguishing system includes: a local voice broadcast device 4, which is connected to the controller 2 and is used to send out an alarm sound signal to remind people in or near the place to evacuate as soon as possible to reduce fire losses; the controller 2 also includes a sound and light control module 25 connected to the main control module 21, and the sound and light control module 25 is connected to the local voice broadcast device 4. The sound and light control module 25 is used to control the switch of the local voice broadcast device 4 according to the output signal of the main control module 21. When it is determined to be a real fire alarm, the main control module 21 sends a signal to the sound and light control module 25, so that the sound and light control module 25 controls the local voice broadcast device 4 to turn on, so as to send out an alarm sound signal, alert the crowd, and evacuate the crowd in time to reduce casualties in the fire.

[0034] The setting of the thermal imaging camera 11 makes the detection signal of the detector group 1 more accurate. When the controller 2 receives the alarm signal of the smoke detector 12 or the temperature detector 13, the controller 2 links the thermal imaging camera 11 and obtains real-time image data and temperature data in the real-time image data. When the temperature data exceeds the set threshold, which is set to 65 degrees Celsius in this embodiment, it is confirmed as a real fire alarm. The controller 2 simultaneously sends a control signal to the local voice broadcast device 4 and an opening signal to the solenoid valve 32 to achieve the purpose of alarm and fire extinguishing.

[0035] The starting end of the pipe network 31 is connected to the municipal water supply system 5, which is used to provide a water source for the simple sprinkler device 3; the simple sprinkler device 3 also includes a pressure sensor 34, which is arranged close to the open sprinkler head 33 and is used to monitor the water pressure of the pipe network 31. The pipe network 31 in this embodiment adopts a DN25 pipe network, that is, a water pipe network, which is generally filled with water and has a large water pressure. When the pressure sensor 34 detects that the water pressure in the pipe network 31 is less than the threshold value, an alarm signal is issued so that the staff can maintain or repair the fire extinguishing system even if necessary, so as to further ensure that the fire extinguishing system can be used normally and more safely.

[0036] Furthermore, the simple sprinkler device 3 also includes a pressure sensor 34, which is arranged near the open sprinkler head 33 and is used to monitor the static water pressure and dynamic water pressure of the pipe network 31. When the simple sprinkler device 3 is damaged or the water supply is cut off and the fire extinguishing action cannot be completed, the pressure sensor 34 connected to the controller 2 can be connected to the controller 2 in time, so that the controller 2 sends an alarm signal to facilitate the staff to promptly inspect and repair the simple sprinkler device 3 to ensure that the simple sprinkler device 3 in the fire extinguishing system can be used normally. In this embodiment, the pipe network 31 adopts a DN25 pipe network, and the solenoid valve 32 adopts a DN25 solenoid valve. The inside of the pipe network 31 is generally filled with water. When the static water pressure detected by the pressure sensor 34 is less than 0.07MPa, the pressure sensor 34 sends an alarm signal.

[0037] The working principle of the utility model is: when one of the smoke detector 12 or the temperature detector 13 reaches the threshold, an alarm signal is sent to the controller 2. After the controller 2 receives the alarm signal, it links the thermal imaging camera 11 to obtain real-time image data and temperature data to judge the authenticity of the fire alarm. When the temperature data is higher than the threshold, the thermal imaging camera 11 sends a signal to the controller 2, and the controller 2 judges it as a real fire alarm. At the same time, a control signal is sent to the local voice broadcast device 4 and an opening signal is sent to the solenoid valve 32, so that the local voice broadcast device 4 sends an alarm sound signal to notify the crowd, and the solenoid valve 32 is opened to turn on the simple sprinkler device 3, draw water from the municipal water supply system 5 and spray water from multiple open sprinkler heads 33 to extinguish the environment.
