The controller 40 controls the fire extinguishing device 30 according to the detector 20 so that the fire extinguishing device 30 releases the fire extinguishing medium into the space where the main board 10 is located.

[0029] It can be understood that the fire extinguishing equipment of the present application can be applied to an energy storage system, for example, it can be applied to an energy storage cabinet. In this case, the mainboard 10 can be fixed on the inner wall of the energy storage cabinet, and the space where the mainboard 10 is located is the space inside the energy storage cabinet.

[0030] It can be understood that the detector 20 of the present application refers to a device for monitoring and detecting fire inside the energy storage system. The detector 20 can detect abnormal temperature, gas emission and other signs that may cause fire in the energy storage system, thereby helping to give early warning.

[0031] The fire extinguishing device provided by the present application can monitor and automatically extinguish fire in real time, suppress and eliminate fire hazards. The detector 20, the controller 40 and the fire extinguishing device 30 are integrated on the mainboard 10, which has the advantages of compact layout, small occupied volume, saving installation space, and is easy to install and debug.

[0032] In some embodiments, the fire extinguishing device further comprises a mounting plate 50 detachably connected with the board surface of the mainboard 10. The mounting plate 50 is arranged in spaced relation with the board surface of the mainboard 10. The controller 40 is fixed between the mounting plate 50 and the mainboard 10. The detector 20 is mounted on the side of the mounting plate 50 away from the controller 40.

[0033] It can be understood that the mounting plate 50 can be provided with a support portion. The mounting plate 50 can be supported to a certain height away from the board surface of the mainboard 10 by the support portion, so that the mounting plate 50 is arranged in spaced relation with the board surface of the mainboard 10.

The temperature detector 22 is used to monitor the temperature data of the space where the mainboard 10 is located.

[0036] It can be understood that the temperature detector 22 can monitor the temperature change of the space where the fire extinguishing device is located in real time. Once the temperature exceeds the preset safety threshold, an alarm mechanism will be triggered. The smoke detector 21 can detect the smoke that may be generated in the space where the fire extinguishing device is located. Once the concentration of the smoke exceeds the safety standard, an alarm will also be issued.

That is, when the data detected by one of the smoke detector 21 or the temperature detector 22 exceeds the preset value, the controller 40 outputs a first early warning passive switching signal to start the alarm.

[0038] Further, the controller 40 is further used for generating a second early warning signal when the smoke concentration data and the temperature data simultaneously exceed the preset value, and the fire extinguishing device 30 is used for starting a fire extinguishing operation according to the second early warning signal. That is, when the data detected by the smoke detector 21 and the temperature detector 22 simultaneously exceeds the preset value, the controller 40 outputs a second early warning passive switching signal to start the fire extinguishing device 30 to release the fire extinguishing medium.

[0039] Understandably, the embodiment of the present application adopts hierarchical early warning, greatly increases the safety, and improves the accuracy of early warning.

[0040] Optionally, the alarm of the embodiment of the present application is an audible and light alarm, which can simultaneously send out two kinds of alarm signals, so as to enhance the warning effect.

It can timely detect and alarm in the early stage of fire occurrence, greatly improving the efficiency and accuracy of fire prevention.

[0050] In some embodiments, the fire extinguishing device further comprises a communication interface, through which data transmission and communication can be realized. Specifically, the communication interface can be one or more of CAN, RS485, and dry contact. In one possible embodiment, the dry contact switch output is normally open, and when the device is activated, the switch is triggered to close. The system can communicate with the upper device through the 485 communication interface, and the upper device can send a control six-way spraying signal through the mous communication protocol. At the same time, the system checks whether the dry contact input signal is connected. If it is connected, the spraying is confirmed, and the valve is opened to spray and extinguish the fire.
