the output of the smoke detector 2 is connected to a first interface IN1 of the system controller 1 and the output of the temperature detector 3 is connected to a second interface IN2 of the system controller 1.
IN an embodiment of the present application, IN order to reduce the number of occupied ports of the system controller, the number of the smoke detectors 2 and the number of the temperature detectors 3 are at least two, and the output ends of the smoke detectors are connected IN parallel and then connected to the first interface IN1, and the output ends of the temperature detectors 3 are connected IN parallel and then connected to the second interface IN 2.
In another embodiment, in the case of abundant port resources of the system controller, each probe is connected to a different port on the system controller. In addition, the ports to which the same type of probe is connected may be connected in parallel within the system controller.
The smoke detectors 2 are respectively arranged at different positions in the space where the protected system is located, and respectively collect the smoke concentration in the installation position range.
The temperature detectors 3 are respectively arranged at different positions in the protected space and respectively collect the temperature in the range of the installation position.
The intake device 4 and the exhaust device 5 are both directly or indirectly connected to an output interface of the system controller 1.
In one embodiment, the intake device 4 and the exhaust device 5 are directly connected to different output interfaces of the system controller 1, and the switching signals output by the output interfaces can directly control the starting or stopping of the intake device 4 and the exhaust device 5.

The system controller 1 controls the on-off state of the switch module according to the information collected by each detector, so as to control the working states of the air inlet device 4 and the air outlet device 5. When the switch module is closed, the air inlet device and the exhaust device are both started and normally run, and when the switch module is disconnected, the air inlet device and the exhaust device are stopped.

The system controller 1 is used for judging whether the protected system meets the alarm condition according to the information collected by each detector, controlling the air inlet device and the exhaust device to work if the protected system meets the alarm condition, and executing other protection actions matched with the alarm condition.

The system controller 1 executes a corresponding protection action according to a protection action instruction issued by the upper management system 1.
In an application scenario, when the system controller determines that the alarm condition is not met according to the information collected by each detector, the information collected by the detectors can also be uploaded to an upper management system, so that a user can feed back a protection action instruction according to the information, for example, although the carbon monoxide concentration does not reach the alarm value, if the carbon monoxide concentration continues to increase, a risk may exist, and at this time, the air intake device and the exhaust device can be started in advance, so as to reduce the carbon monoxide concentration.
For example, a user may issue a start instruction of the intake device and the exhaust device to the system controller 1 through the upper management system, and the system controller 1 controls the intake device and the exhaust device to start according to the start instruction; for another example, the upper management system is further connected to a water fire fighting system, and the user can also directly control the water fire fighting system (for example, a device for water fire fighting arranged in the protected system) to act through the upper management system according to the information reported by the system controller, so as to perform water fire fighting and fire extinguishing on the protected system.
In other embodiments of the present application, as shown in fig. 2, the fire fighting system further comprises a display module 8 connected to the system controller 1. The display module 8 may be a touch screen or other display screen.

The traditional smoke detector 2 is a passive type, in which smoke in the outside air diffuses into the probe and can be detected and alarm only when the smoke reaches a certain concentration.
In one embodiment of the present application, the very early smoke detector 11 generates and transmits an early warning signal to the system controller 1 when it detects that the smoke concentration reaches the first preset smoke concentration value.
When the smoke detector 2 detects that the smoke concentration value in the air reaches a second preset smoke concentration value, a fire alarm signal is generated and transmitted to the system controller 1. Wherein the first preset smoke concentration value is far smaller than the second preset smoke concentration value.
When the system controller 1 receives the early warning signal sent by the very early smoke detector 11, the protected system is controlled to execute corresponding protection action. For example, the protected system is an energy storage system, and the protection action here can be the shutdown of an energy storage converter, the disconnection of an energy storage battery and the shutdown of a temperature control device.
