s101, receiving a first enabling signal sent by a remote control switch.
In this embodiment, the remote control switch is located outside the hoistway of the elevator, and specifically, the remote control switch may be disposed outside the hall in an overhaul cabinet, for example, in an emergency and test operation panel of the hall in an overhaul cabinet, and the power supply mode of the remote control switch may be selected for ac or dc power supply input. The enable signal refers to an enable signal in the power supply circuit responsible for input and output of the control signal. The remote control switch is used for sending a remote control signal to a control circuit for controlling the main switch in the control cabinet, and the remote control signal is used as an enabling signal for driving the main switch to be switched on and off.
In one implementation manner of the embodiment, an enable signal sent by a remote control switch is received; and if the enabling signal is in a high level, determining that the enabling signal is the first enabling signal, wherein the high level indicates that the remote control switch is in a closed state.
S102, detecting a first closed state of the control cabinet.
In this embodiment, a detection device is disposed in the control cabinet, and the detection device can be used to detect a first closed state of the control cabinet, where the closed state includes an open state and a closed state.
The detecting device may be a magnetic switch, a travel switch, or other sensors for detecting a distance, which is not limited in this embodiment of the present invention.
The detection device is used for detecting whether a cabinet door of the control cabinet is opened or not, if the cabinet door is opened, the first closed state where the control cabinet is located currently is an open state, and if the cabinet door is closed, the first closed state where the control cabinet is located currently is a closed state.
In this embodiment, the detection device will send a detection signal, and as shown in fig. 2B, the control circuit and the alarm in the control cabinet can determine the first closed state of the control cabinet by receiving the detection signal.
For example, detect the first closed state of switch board through the magnetic switch, because the magnetic switch can pass through the position relation change between sensor and the object, turn into non-electric quantity or electromagnetic quantity the signal of telecommunication to reach the purpose that detects the cabinet door position, consequently, can judge through the signal of telecommunication (detected signal) of magnetic switch feedback that first closed state is in closed condition or open condition.
For another example, the first closed state of the control cabinet is detected through a travel switch, the travel switch is a low-current master control electrical appliance, the travel switch can be installed at a position arranged in the control cabinet in advance, when a certain module on a cabinet door component impacts or approaches the travel switch, a contact of the travel switch acts, and whether the first closed state is in a closed state or an open state is judged by obtaining a detection signal when the contact of the travel switch acts.
S103, setting a first operation mode matched with the first closed state for a main switch in the control cabinet.
In this embodiment, the main switch is provided with a small motor, and the operation of the small motor can realize the on/off control of the main switch, wherein the main switch can be a circuit breaker, the circuit breaker refers to a switching device which can close, bear and open the current under the condition of a normal loop and can close, bear and open the current under the condition of an abnormal loop within a specified time, and the circuit breaker is connected with a main loop for supplying power to the elevator and has the functions of overcurrent and short-circuit protection.
And setting a first operation mode matched with the first closed state for a main switch in the control cabinet, wherein the operation mode comprises an automatic switching mode and a manual switching mode, when the main switch is in the manual switching mode, the remote control fails, and when the main switch is in the automatic mode, the remote control is effective.

In this embodiment, when the detection device in the control cabinet detects that the cabinet door is normally closed, the detection device sends a detection signal, the detection signal is transmitted to the alarm in the control cabinet, and at this time, the first closing state of the control cabinet is a closing state, and then the alarm in the control cabinet is driven to perform an alarm operation. Wherein the alarm may be an acoustic/optical alarm device.
In a specific implementation manner of this embodiment, as shown in fig. 2B, the remote control switch K1 has two normally open contacts, one of which is used to provide a control signal to the control circuit of the main switch, and the other is used to provide a control signal to the alarm in the control cabinet, when the two contacts are closed, the control circuit controls the small motor of the main switch to operate, so as to drive the main switch to close, and at the same time, the sound and light alarm device emits a sound and light alarm, and stops after a duration of T (e.g. 3S).
In this embodiment, because the remote control switch sends the remote control signal, when the main switch responds to the control signal and completes the conduction of the power supply circuit, a certain time delay exists, when the remote control switch is closed, the alarm is driven to execute the alarm operation, the main switch in the elevator power supply circuit is in an action state for reminding field workers, and the alarm sounds to remind the workers in the hoistway, so that the workers are prevented from contacting with the charged elements in the elevator.
In this embodiment, the remote control switch has locking device, and this locking device of staff's operation before getting into the well can be operated and the risk that the personnel maloperation brought outside the room is avoided to the remote control switch locking.
And S104, if the first operation mode is the automatic switching mode, responding to the first enabling signal, and driving the main switch to be closed so as to enable the power supply circuit of the elevator to be conducted.
In this embodiment, if the first operation mode of the main switch is the automatic switching mode, the control circuit in the control cabinet drives the small motor in the main switch to operate in response to the first enable signal sent by the remote control switch, and controls the main switch to close so as to conduct the power supply circuit of the elevator.
In this embodiment, if the first operation mode of the main switch is the manual switching mode, the control circuit in the control cabinet ignores the first enable signal, and at this time, the main switch does not operate.
