In order to save space in the machine room-less elevator, the control cabinet, main engine, speed limiter and other equipment that were previously installed in the machine room above the hoistway were changed to be installed in the hoistway, and the special machine room setting was cancelled, which effectively improved the utilization rate of the building area and reduced the the construction cost.

In the design of machine room-less elevators, the maintenance cabinet outside the hall generally refers to the auxiliary control cabinet located next to the hall door on the top floor of the elevator. The maintenance cabinet outside the hall is often referred to as emergency and test operation devices in the elevator industry, mainly including emergency operation panels and test operations. The screen is specially designed for machine room-less elevators.

Fig. 1A shows a schematic diagram of the position design of the main switch in the power supply circuit of a conventional machine room-less elevator. FIG. 1B shows a schematic diagram of the main switch circuit in the power supply circuit of a machine room-less elevator in the existing elevator design. As shown in Figure 1B, the existing machine room-less elevator is designed to set the main switch in the emergency and test operation screens outside the hall (a circuit breaker is selected, which has overcurrent and short-circuit protection functions, which can not only realize power-off and power-on operation, but also have a protective effect. ), set the isolation switch in the control cabinet in the hoistway (this switch only realizes the operation of power-off and power-on, and has no protective effect. If a circuit breaker is used, the circuit is overloaded or short-circuited, when the switch acts, the circuit breaker protection is disconnected, and after the fault is eliminated , because the switch is installed in the hoistway and cannot be touched or reset), the control cabinet is provided with a main circuit for powering the elevator. The main circuit is used as the elevator power drive circuit, which includes filters, frequency converters, contactors and other equipment. As shown in Fig. 1B, the elevator power supply circuit can only realize manual power-off operation outside the hall and in the hoistway.

In order to solve the problems existing in the design of the existing machine room-less elevator, as shown in Figure 2A, the technical solution of the present invention applies a design in which the main switch is installed in the hoistway, so that the material configuration of the emergency and test operation panels is independent of the elevator specifications , can be designed in a unified way, as a common module, which is convenient for production management, and because it does not contain strong electric parts, the cabinet design is small in size, which reduces the impact of emergency and test operation screens on the decoration of the user's hall. In addition, due to the removal of the main switch, emergency There is no direct connection between the circuit of the test operation panel and the power supply, the design is simpler, and the power line does not need to be turned, and can be directly connected to the control cabinet, reducing the overall cost.

Example 1

3 is a flowchart of a method for controlling an elevator power supply circuit provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation in which the elevator power supply circuit is controlled. Mode to illustrate, the method is applied to the control cabinet of the elevator, the control cabinet is arranged in the hoistway where the elevator is located, the method can be executed by the control device of the elevator power supply circuit, and the control device of the elevator power supply circuit can be controlled by software and/or Hardware implementation can be configured in computer equipment, such as servers, controllers, control cabinets, management system platforms, etc. The method specifically includes the following steps:

S101. Receive a first enable signal sent by a remote control switch.

In this embodiment, the remote control switch is located outside the hoistway of the elevator. Specifically, it can be set in the maintenance cabinet outside the hall, for example, in the emergency and test operation screens of the maintenance cabinet outside the hall. The power taking method of the remote control switch can be selected. AC or DC power input. The enable signal refers to the allowable signal in the power supply circuit responsible for the input and output of the control signal. The remote control switch is used to send a remote control signal to the control circuit in the control cabinet that controls the main switch, and the remote control signal is used as an enabling signal for driving the main switch to close and open.

In an implementation of this embodiment, the enable signal sent by the remote control switch is received; if the enable signal is at a high level, the enable signal is determined to be the first enable signal, and the high level indicates that the remote control switch is in closed state.

S102. Detect the first closed state that the control cabinet is currently in.

In this embodiment, a detection device is provided in the control cabinet, and the first closed state that the control cabinet is currently in can be detected by the detection device, and the closed state includes an open state and a closed state.

The detection device may be a magnetic switch, a travel switch, or other sensors for detecting distance, which are not limited in this embodiment of the present invention.

The detection device is used to detect whether the cabinet door of the control cabinet is open. If the cabinet door is open, it means that the first closed state of the control cabinet is the open state. If the cabinet door is closed, it means that the first closed state of the control cabinet is currently located. Status is off.

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, the first closed state of the control cabinet is detected by the magnetic switch. Since the magnetic switch can change the positional relationship between the sensor and the object, it can convert non-electrical or electromagnetic quantities into electrical signals to achieve the purpose of detecting the position of the cabinet door. Therefore, it can be determined whether the first closed state is in the closed state or the open state through the electrical signal (detection signal) fed back by the magnetic switch.

For another example, the first closed state of the control cabinet is detected by the travel switch. The travel switch is a low-current master electrical appliance. The travel switch can be installed in a pre-arranged position in the control cabinet. When hitting or approaching the travel switch, the contacts of the travel switch act, and it is judged whether the first closed state is in the closed state or the open state by acquiring the detection signal when the travel switch contacts act.

S103. Set a first operation mode adapted to the first closed state for the main switch in the control cabinet.

In this embodiment, the main switch has a small motor, and the operation of the small motor can realize on/off control of the main switch, wherein the main switch can be a circuit breaker, and the circuit breaker refers to the ability to close, load and open The current under normal circuit conditions is a switch device that can close, carry and break the current under abnormal circuit conditions within a specified time. The circuit breaker is connected to the main circuit that supplies power to the elevator and has overcurrent and short circuit protection functions.

The main switch in the control cabinet is set to a first operating mode adapted to the first closed state. The operating mode includes automatic switching mode and manual switching mode. When the main switch is in the manual switching mode, the remote control is invalid. When the main switch is in the automatic mode When the remote control takes effect.

Specifically, if the first closed state of the control cabinet is the open state, the first operation mode of the main switch is set to the manual switching mode; if the first closed state of the control cabinet is the closed state, the first operation mode of the main switch is set to The mode is set to automatic switching mode.

Normally, the doors of the control cabinet are closed, that is, the first closed state is the closed state, and the first operating mode of the main switch can be set to the automatic switching mode by default. When the first closed state of the cabinet is the open state, the first operating mode of the main switch is switched from the automatic switching mode to the manual switching mode. In the manual switching mode, the remote control becomes invalid.

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, and the detection signal is transmitted to the alarm in the control cabinet. At this time, the first closed state of the control cabinet is Off state, then drive the alarm in the control cabinet to perform alarm operation. Wherein, the alarm may be an audible/optical alarm device.

In a specific implementation 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 control circuit of the main switch. It is used to provide control signals to the alarms in the control cabinet. When the two contacts are closed, the control circuit controls the operation of the small motor of the main switch, and drives the main switch to close. (such as 3S) and then stop.

In this embodiment, there will be a certain time delay when the remote control switch sends the remote control signal and the main switch completes the conduction of the power supply circuit in response to the control signal. When the remote control switch is closed, the alarm is driven to perform an alarm operation. The purpose is to remind the on-site staff that the main switch in the elevator power supply circuit is in action, and the alarm sound can remind the staff in the hoistway to prevent the staff from touching the live components in the elevator.

In this embodiment, the remote control switch is provided with a locking device, and the staff can operate the locking device to lock the remote control switch before entering the hoistway, so as to avoid the risk of misoperation by people outside the hall.

S104. If the first operation mode is the automatic switching mode, in response to the first enable signal, the main switch is driven to be closed, so that the power supply circuit of the elevator is turned on.

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 run in response to the first enable signal sent by the remote control switch, and controls the main switch. The switch is closed to turn on the power supply circuit of the elevator.

In this embodiment, if the first operating mode of the main switch is the manual switching mode, the control circuit in the control cabinet ignores the first enable signal, and the main switch does not act at this time.

The control method of the elevator power supply circuit provided by the embodiment of the present invention is applied to the control cabinet of the elevator, and the control cabinet is arranged in the hoistway where the elevator is located. The method receives the first enable signal sent by the remote control switch, and the remote control switch is located in Outside the hoistway of the elevator; detect the current first closed state of the control cabinet; set the first operation mode adapted to the first closed state for the main switch in the control cabinet; if the first operation mode is the automatic switching mode, respond In response to the first enable signal, the main switch is driven to close, so that the power supply circuit of the elevator is turned on. Among them, the remote control switch is arranged outside the hoistway to facilitate automatic control of the elevator power supply circuit, and the main switch is arranged in the control cabinet in the hoistway, and the power supply box can be directly connected to the control cabinet, eliminating the need for traditional wiring. The power supply cabinet is first connected to the emergency and test operation panels, and then the emergency and test operation panels are connected to the control cabinet. The design and layout of the elevator power supply circuit of the technical solution of the present application can reduce the length of the power line and reduce the engineering cost. At the same time, The main switch is set in the control cabinet, so there is no need to occupy the maintenance cabinet outside the hall, so that the strong and weak current modules in the traditional machine room-less elevator layout are separated from the strong and weak current modules in the test operation screen, and there is no need to consider the electromagnetic compatibility problem when designing the maintenance cabinet outside the hall. It will not affect the decoration outside the hall, which can save the design cost of the maintenance cabinet outside the hall; before the main switch responds to the enable signal, the operation mode of the main switch is judged by detecting the closed state of the control cabinet. When the operation mode is the automatic switching mode, Only respond to the enable signal sent by the remote control switch to realize the conduction of the power supply circuit, which can avoid the need for the control cabinet to be opened due to maintenance or emergency, while the power supply circuit still responds to the remote control command. The risk of electric shock when the control cabinet is overhauled. At the same time, when the closed state of the control cabinet and the operating mode of the main switch are limited, the enabling signal of the remote control switch can be received, which can quickly realize the power-on and power-off of the elevator power supply circuit without on-site inspection. The power supply circuit performs power-off and power-on operations. When encountering an elevator emergency, the power-off operation can be quickly performed to reduce the response time of power supply failures.
