[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0029] like Figure 1-Figure 3 As shown, in one embodiment, a built-in control module for a fan in an energy storage box includes: a fire control module, a contactor and a TC terminal. The fire control module is connected to the contactor through a wire, the contactor is electrically connected to the TC terminal through a wire, and the TC terminal is electrically connected to the fire fan and the actuator through a wire.

[0030] like Figure 1-Figure 3 As shown, in this embodiment, the fire control module consists of a fire input signal and power input unit, a power conversion unit and a fire alarm output unit, and is mainly used to monitor the operating status of the ventilation and smoke exhaust system.

[0031] Among them, the fire input signal module is used to connect the contactor, and its function is to control the start or stop of the fire fan to quickly discharge the smoke and harmful gases in the energy storage box; the power input unit is responsible for providing stable and reliable power support for the ventilation and exhaust system, ensuring that the system can maintain stable operation under various working conditions and that the equipment can work normally; the power conversion unit is used to convert AC power into 24V DC power to power the actuator; the fire alarm output unit has a variety of dry contact output signal functions, which can trigger the corresponding alarm device when necessary, convey the emergency situation to relevant personnel and take corresponding safety measures, so as to maximize the safety of personnel and property.

[0032] like Figure 1-Figure 3 As shown, in this embodiment, the fire control module includes a main panel, and two upper and lower rows of TC terminals are arranged on the main panel.

[0033] Among them, the upper row of TC terminals include main power input terminals, linkage fan opening input terminals, fire linkage fan closing input terminals, manual fan start and stop input terminals, fan opening signal output terminals, shutter opening signal output terminals, system fault signal output terminals, Modbus485 signal terminals, system power-off signal output terminals and dry contact output terminals; the lower row of wiring terminals include actuator power supply terminals and fan power supply terminals.

[0034] Specifically, the main power input terminal is used to connect the main power supply to provide stable power support;

[0035] The linkage opening fan input terminal can realize linkage control of the fan in the ventilation and exhaust system through the contactor;

[0036] The fire linkage shutdown fan input terminal is to shut down the fan in time through the contactor in case of fire or other emergency situations to prevent the spread of smoke and harmful gases;

[0037] The manual start and stop fan input terminal is for the convenience of manual start and stop operation of the fan; the fan start signal output terminal and the shutter open signal output terminal are used to control the fan and the shutter;

[0038] The system fault signal output terminal outputs the corresponding fault signal when the system fails, prompting the staff to carry out inspection and maintenance;

[0039] The Modbus485 signal terminal is used to monitor the operating status of the ventilation and exhaust system and determine whether to start and reset it;

[0040] The system power-off signal output terminal facilitates relevant personnel to quickly confirm the situation after the ventilation and exhaust system loses power;

[0041] There are two groups of dry contact output terminals, which are used to output fire alarm signals;

[0042] The actuator power supply terminal is used to provide 24V power supply to the electric blinds;

[0043] The fan power supply terminal is used to provide 220V power supply to the fan.

[0044] like Figure 1-Figure 3 As shown, in this embodiment, the ventilation and exhaust system mainly consists of two parts: a ventilation and exhaust device and a fan. The ventilation and exhaust device includes an air inlet device and an air exhaust device. The air inlet device is used to introduce external air into the ventilation duct, and the air exhaust device is responsible for exhausting harmful gases in the energy storage box. The ventilation and exhaust device uses electric shutters.

[0045] Furthermore, the ventilation and exhaust device and the actuator are controlled by electrical connection. The actuator can control the opening and closing of the shutter according to the instructions of the system to achieve different ventilation effects. At the same time, the actuator can also send information about the current state to the system through feedback signals so that the system can monitor and control in real time.

[0046] In addition, the Modbus485 signal terminal can be used to monitor the ventilation and exhaust system status in real time. The real-time status includes:

[0047] (1) Inlet shutter open state, inlet shutter closed state, inlet shutter fault state (actuator not open / reset to the specified angle), when the air inlet device fails, the Modbus485 signal terminal outputs the actuator fault signal;

[0048] (2) Exhaust louver open state, exhaust louver closed state, exhaust louver fault state (actuator not open / reset to the specified angle), when the exhaust device fails, the Modbus485 signal terminal outputs the actuator fault signal;

[0049] (3) Fan on state, fan off state, fan fault state (slow speed / no rotation). When the fan fails, the Modbus485 signal terminal outputs a fan fault signal.

[0050] Working principle:

[0051] When the gas detector in the energy storage box detects that the concentration of combustible gas reaches the low threshold (10% LEL), it sends a first-level fire alarm signal, and then the fire control module drives the ventilation and exhaust system to start working, the actuator drives the ventilation and exhaust device to start, and the fan starts working: when it is detected that the concentration of combustible gas continues to decrease, the ventilation and exhaust system is closed; when it is detected that the concentration of combustible gas continues to rise, the ventilation and exhaust system continues to work;

[0052] When the gas detector in the energy storage box detects that the concentration of combustible gas reaches the high threshold (20% LEL), it sends a second-level fire alarm signal. Then the fire control module drives the ventilation and exhaust system to stop working, the actuator drives the ventilation and exhaust device to open, and the fan is forced to close.

[0053] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
