step S601, firstly, setting the brightness of the lamplight to be zero, and if the brightness of the lamplight is not adjustable, turning off the lamplight equipment;
measuring a current value;
comparison with a pre-stored current value of brightness "zero" or "off":
if the current value is smaller than the value measured in advance, a fault code is sent to the remote controller and the remote controller continues to operate;
if the current value is larger than the value measured in advance, a danger level fault code is sent to the remote controller, and the lighting equipment is closed;

comparing with the prestored current value under the same state:
if the current value is smaller than the value measured in advance, a fault code is sent to the remote controller and the remote controller continues to operate; if the current values are equal or close, the operation is continued;
when receiving a brightness setting command sent by a local remote controller, setting the brightness of the lamplight; measuring a current value; comparing with the prestored current value in the same state, if the current value is less than the value measured in advance, sending a fault code to the remote controller and continuing to operate; if the current values are equal or close, the operation is continued;

When the device is used, all the light devices can be controlled to be turned on, turned off, changed in brightness and changed in color respectively to measure the current value in various states. If the measured current value is not within the normal range, all the current values are closed and then are opened one by one, and the method of changing brightness and changing color is used for determining the position of the faulty light.
