[0022] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0023] Referring to Figure 1 As shown in the figure, it is a module schematic diagram of the present application.

[0024] The system comprises a remote control module, a floor call module and at least one elevator control module, the remote control module is wirelessly connected with the at least one elevator control module, and the remote control module is wirelessly connected with the floor call module;

[0025] The floor call module is used to receive an elevator control request of a first user and send the elevator control request to the remote control module;

[0026] The remote control module is used to generate a control instruction according to the elevator control request and send the control instruction to the elevator control module corresponding to the control instruction;

[0027] The elevator control module is used to control the operation of the elevator according to the control instruction.

[0028] In the embodiment, the remote control module can be installed in a remote control box, the remote control box can be controlled by a monitoring personnel of the elevator (for example, a construction elevator), the floor call module can be a floor call device, which is a wireless device used in the construction elevator, and there is a call device on each floor. When the construction personnel on the floor needs to use the elevator, the call button on the floor can be pressed to call the elevator. The elevator control module can be installed in the interior of the cage of the construction elevator, and the elevator control module is used to control the operation of the elevator according to the instruction of the remote control module. One remote control module is wirelessly connected with multiple elevator control modules, that is, one remote control module can control the operation of multiple construction elevators.

[0029] The floor call module is used to receive an elevator control request of a first user (referred to as a first user) and send the elevator control request to the remote control module, for example, the construction personnel on the 8th floor of the construction building press the call button, and the floor call module sends the elevator control request to the remote control module;

[0030] The remote control module is used to generate a control instruction according to the elevator control request and send the control instruction to the elevator control module corresponding to the control instruction. For example, after receiving the request sent by the floor call module, the remote control generates a control instruction. If the control instruction is to control the elevator on the left side of the construction building to run to the 8th floor, the control instruction will be sent to the elevator control module corresponding to the elevator on the left side of the construction building. Further, the remote control module can calculate based on the operating conditions of multiple elevators, select an elevator from multiple elevators according to the calculation result to generate the control instruction corresponding to the elevator, and send the control instruction to the elevator control module corresponding to the elevator.

[0031] The elevator control module is used to control the operation of the elevator according to the control instruction. After receiving the control instruction, the elevator control module controls the operation of the elevator according to the control instruction. For example, if the control instruction is to control the elevator on the left side of the construction building to run to the 8th floor, the control module of the elevator on the left side of the construction building controls the elevator to run to the 8th floor.

[0032] See Figure 2 As shown, it is a schematic diagram of the remote control module and the floor call module of the elevator remote control system of this application. The floor call module includes a floor call host unit and multiple floor call extension units. The floor call host unit is wirelessly communicatively connected to each of the floor call extension units. The floor call extension unit is used to receive the elevator control request of the first user and send it to the floor call host unit.

[0033] A floor call extension unit is installed on each floor of the construction building. Construction workers can make the elevator run to this floor through the call button of the floor call extension unit. When the construction workers on a certain floor press the call button, the floor call extension unit on this floor sends the elevator control request of the construction workers to the floor call host unit.

[0034] Further, the remote control module includes a first MCU control unit. The first MCU control unit is connected to the floor call host unit. The floor call host unit is used to send the elevator control request to the first MCU control unit. The first MCU control unit is used to generate the control instruction according to the elevator control request and send the control instruction to the elevator control module corresponding to the control instruction. The remote control module also includes a wireless control transmitting and receiving unit. The wireless control transmitting and receiving unit is connected to the first MCU control unit. The remote control module communicates with the elevator control module through the wireless control transmitting and receiving unit.

[0035] The first MCU control unit refers to a microcontroller unit (MCU). The first MCU control unit and the floor call host unit can be connected in communication through an RS-485 interface. After the floor call host unit receives the goods elevator control request from the floor call extension unit, the floor call host unit sends the goods elevator control request to the first MCU control unit. The first MCU control unit generates a control instruction according to the goods elevator control request and sends the corresponding goods elevator control module. For example, if the remote control module is connected in communication with the goods elevator control modules on the left and right sides of the construction building, a construction worker on a certain floor of the construction building initiates a goods elevator control request through the floor call extension unit on the floor. When the first MCU control unit receives the goods elevator control request, the first MCU control unit can generate a control instruction for the right-side goods elevator and send the control instruction to the goods elevator control module of the right-side goods elevator, so that the goods elevator control module of the right-side goods elevator controls the right-side goods elevator to run to the floor. Alternatively, the first MCU control unit can generate a control instruction for the left-side goods elevator and send the control instruction to the goods elevator control module of the left-side goods elevator, so that the goods elevator control module of the left-side goods elevator controls the left-side goods elevator to run to the floor.

[0036] Further, the remote control module further comprises a voice playing unit connected with the first MCU control unit.

For example, the voice module plays a voice of "8th floor needs to use the goods elevator". After the staff of the remote control box hears the played voice, the staff manually presses the layer selection key of the remote control box, so as to control the goods elevator to run to the 8th floor.

[0038] Further, the remote control module further comprises at least one floor command unit, the floor command unit is connected with the first MCU control unit, the floor command unit comprises a floor selection unit and a limit emergency stop signal detection unit, the floor selection unit is used for receiving a lift control request of a second user, and the limit emergency stop signal detection unit is used for sending a stop signal to the first MCU control unit when the limit emergency stop signal triggered by the lift is detected, so that the first MCU control unit sends the stop signal to the lift control module, and the lift control module stops running the lift according to the stop signal.

[0039] The remote control module further comprises at least one floor command unit, for example, a floor command unit corresponding to a left lift of the construction building and a floor command unit corresponding to a right lift of the construction building. The floor command module comprises a floor selection unit and a limit emergency stop signal detection unit. The floor selection unit is used for receiving a lift control request of a second user (for example, a driver controlling the lift). For example, in the working mode with the driver operating, the driver presses the floor selection button (the floor selection button can have an LED indicator), the first MCU control unit generates a corresponding lift control instruction after receiving the instruction triggered by the floor selection button, and sends the lift control instruction to the corresponding lift control module, and the lift control module controls the corresponding lift to run. Various types of limit switches are installed in the lift shaft of the lift, and the limit switches generate limit emergency stop signals when triggered and send the limit emergency stop signals to the limit emergency stop signal detection unit. The limit emergency stop signal detection unit is used for sending a stop signal to the first MCU control unit when the limit emergency stop signal triggered by the lift is detected, so that the first MCU control unit sends the stop signal to the lift control module of the lift, and the lift control module stops running the lift according to the stop signal.

[0040] Further, the remote control module further comprises a human-computer interaction unit, the human-computer interaction unit is connected with the first MCU control unit, and the human-computer interaction unit is used for displaying the running state of the lift.
