and S101, carrying out fault detection on the fan.
It should be noted that, the fault of the fan is not limited too much, for example, the fault includes but is not limited to a failed start (such as a failed switch), an early stop, an abnormal operating parameter, and the like. The operation stopping in advance can include that the fan stops operating under the condition that the fan is started and at least one of the fan, the driving motor and the belt conveyor is not received.
It should be noted that the shutdown command is not excessively limited. For example, the user may send a stop instruction of at least one of the fan, the driving motor, and the belt machine in a manner of a remote controller, a control program of the belt machine in the server, an operation panel on the body of the belt machine, and the like.
In one embodiment, the fault detection of the wind turbine may include the following two possible embodiments:

Alternatively, in response to the switching state of each sub-switch being the closed state, the switching state of the main switch is determined to be the closed state. Therefore, the switching state of each sub-switch can be comprehensively considered in the method to determine the switching state of the main switch.
Therefore, whether the fan breaks down or not can be determined according to the on-off state of the main switch of the fan in the method.
And 2, detecting the value of the operating parameter of the fan, identifying that the value of the operating parameter is not in a set range, and determining that the fan breaks down.
It should be noted that the setting range refers to a reference range of values of the operating parameters of the fan, and may be preset according to an actual situation.

Therefore, when the fan breaks down, the driving motor can be controlled to stop running, the driving motor can be prevented from running when the fan breaks down, the risk of overhigh temperature of the driving motor is greatly reduced, the running safety and reliability of the driving motor are improved, and the running safety and reliability of the belt conveyor are further improved.
On the basis of any one of the above embodiments, in the case that the driving motor is not started, the method further includes controlling the driving motor to start in response to the fan not having a fault. Therefore, in the method, the driving motor can be controlled to be started when the driving motor is not started and the fan is not in fault.
In one embodiment, before controlling the driving motor to start, the method further comprises receiving a starting instruction of the driving motor and/or receiving a starting instruction of the belt conveyor. It should be noted that, for the relevant content of the start instruction, reference may be made to the relevant content of the shutdown instruction in the foregoing embodiment, and details are not described here.

The frequency converter 3 is a frequency converter for driving the motor 1.
The normally open point of the sub-switch 51 is connected with the common end of the output end of the frequency converter 3, the common end of the sub-switch 51 is connected with the normally open point of the sub-switch 52, the common end of the sub-switch 52 is connected with one operation feedback point of the input end of the main controller 4, and the other operation feedback point of the input end of the main controller 4 is connected with the normally open point of the output end of the frequency converter 3.
The common terminal of the output terminals of the frequency converter 3 can output the feedback signal of the frequency converter 3. It should be noted that the feedback signal of the frequency converter 3 is not limited too much, for example, the feedback signal of the frequency converter 3 is used for indicating the operation state of the frequency converter 3, wherein the operation state includes start and non-start.
As shown in fig. 3, when the main switch 5 is in a closed state, that is, when both the sub-switch 51 and the sub-switch 52 are in a closed state, a feedback signal of the frequency converter 3 may be sent to the main controller 4 through the main switch 5, and the main controller 4 may control the frequency converter 3 to continue to operate to control the driving motor 1 to continue to operate when the frequency converter 3 is started after receiving the feedback signal of the frequency converter 3, or may control the frequency converter 3 to start to control the driving motor 1 to start in response to receiving a starting instruction of the driving motor and/or the belt conveyor when the frequency converter 3 is not started.
When the main switch 5 is in an off state, that is, at least one of the sub-switches 51 and 52 is in an off state, the feedback signal of the frequency converter 3 cannot be sent to the main controller 4 through the main switch 5, and the main controller 4 can control the frequency converter 3 to stop operating after not receiving the feedback signal of the frequency converter 3, so as to control the driving motor 1 to stop operating.
Therefore, the main switch of the fan can be added into the control circuit of the driving motor in the scheme, and then the driving motor can be controlled to stop running when the main switch of the fan is in an off state, namely the driving motor is controlled to stop running when the fan is not started, so that the running safety and reliability of the driving motor are improved.
