[0058] ​The fan controller includes a low-voltage circuit breaker 1, a group of terminal rows 2, a relay one 301, a relay two 302 and a switching power supply 4. The relay one 301 and the relay two 302 can control two fan AC fan motors and four fan DC fan motors respectively. All electrical elements of the fan controller are integrated in a distribution box, and the fan controller has simple control principle, less electrical elements, and can effectively control the size of the fan controller, and save installation space during installation and use. A start indicator lamp 5, a stop indicator lamp 6, a manual-automatic switching knob 7 and a manual start knob 8 are arranged in front of the distribution box door of the fan controller.

[0059] The switching power supply 4 of the fan controller is connected through the low-voltage circuit breaker 1, and the circuit breaker is used for protecting the circuit of the whole fan controller to prevent current overload. The connected switching power supply 4 provides necessary power for the fan controller to enable normal work. The relay one 301 and the relay two 302 are used for controlling the AC fan motor of the fan, and the AC fan motor is the power source of the fan. In the part of controlling the DC fan motor, the fan controller has the control ability of multiple fan DC fan motors, and the control logic of the fan DC fan motors is that the fan DC fan motor continuously reverses before triggering and continuously rotates positively after triggering.

[0060] The start indicator lamp 5 and the stop indicator lamp 6 are installed in front of the distribution box door of the fan controller and are used for indicating the working state of the fan controller. The start indicator lamp 5 is lighted when the fan controller is in a running state, and the stop indicator lamp 6 is lighted when the fan controller is in a stop state. The manual-automatic switching knob 7 and the manual start knob 8 are also installed in front of the distribution box door of the fan controller. The manual-automatic switching knob 7 is used for switching between the manual mode and the automatic mode. In the manual mode, only the manual start knob 8 on the distribution box door of the fan controller can control the start of the fan motor. The design in the manual mode is to increase the safety of operation and to ensure that the fan motor is started only after the operator confirms. In the automatic mode, the fan motor can be started and stopped through an external start signal source, which enables the fan controller to be linked with an external system for linkage control and automatic operation.

[0061] When the low-voltage circuit breaker 1 is closed, the power supply supplies power to the fan controller, and the fan controller starts to work. The operator can select the working mode through the manual-automatic switching knob 7. In the manual mode, the operator rotates the manual start knob 8, and the fan controller starts the corresponding fan motor through the relay one 301 and the relay two 302. In the automatic mode, the fan controller controls the start and stop of the fan motor through an external start signal source. The fan DC fan motor continuously reverses in the untriggered state, and switches to positive rotation when receiving the trigger signal. Embodiment

[0062] The circuit breaker is arranged inside the fan controller to protect the entire circuit from current overload. In the event of current overload or short circuit, the circuit breaker will quickly cut off the circuit to protect the fan controller and the fan motor. Power supply: provides stable power to ensure the normal operation of the fan controller and the fan motor. Two relays: used to control the AC fan motor respectively. By controlling the opening and closing of the relay, the fan motor can be started and stopped. In the non-trigger state of the relay, the DC fan motor continuously reverses; when receiving the trigger signal, the DC fan motor switches to forward rotation.

[0063] Fan controller control panel operation indicator light, indicating the running state of the fan controller, when the fan controller controls the fan motor to work, the start indicator light is on. Stop indicator light: indicates that the controller is in a stop state, when the controller stops working, the stop indicator light is on. Start knob: used to start the motor in manual mode. Only by pressing the start knob, the fan motor will start, thus increasing the safety of operation. Manual-automatic switching knob: used to switch between manual mode and automatic mode. In manual mode, the user needs to press the start knob to start the fan motor; in automatic mode, the fan motor can be started and stopped by the external dry contact signal.

[0064] There are two working modes, manual mode and automatic mode. In manual mode, the user can select manual mode through the manual-automatic switching knob, and in manual mode, the manual start knob on the fan controller cabinet door must be turned on to start the fan motor. This design increases the safety of operation, ensuring that the fan motor can only be started after manual confirmation. Automatic mode: the user can select automatic mode through the manual-automatic switching knob, and in automatic mode, the controller can start and stop the fan motor through the external dry contact signal. This allows the controller to be linked with external systems to automatically control the operation of the fan.

[0065] The control logic of the DC fan motor is as follows: in the non-trigger state, the DC fan motor continuously reverses; when receiving the trigger signal, the DC fan motor switches to forward rotation. This design allows the DC fan motor to achieve different working states according to the demand, increasing the flexibility of control. The fan controller of the utility model realizes efficient control of various types of fan motors through the above structure and function design, and improves the convenience and safety of operation, and is especially suitable for fan systems that require multiple motors to work together.
