Description

Technical Field

[0001] This invention belongs to the field of elevator car technology, specifically relating to an input device and method for operating car commands. Background Technology

[0002] To meet certain specific needs, a switch box is typically installed inside the elevator car control panel. This switch box contains several physical switches used to turn certain devices on or off. Because existing elevator car control panels contain multiple physical switches controlling the on / off operation of related equipment, the structure of the control panel is relatively complex, and the control circuits involved in the physical switches are also complex, resulting in high manufacturing costs. Furthermore, to prevent unauthorized personnel from accidentally operating these physical switches, a switch lock using a special key is usually installed on the switch box. These special requirements typically include the following aspects:

[0003] 1. In order to meet the needs of maintenance and repair, a check switch is usually installed in the switch box. When the check switch is switched to the open state, the elevator is disconnected from normal service and is exclusively for maintenance personnel to operate and control the elevator.

[0004] 2. To meet the needs of the property management or owners, switches for lights and fans are usually installed in the switch box to turn the elevator car lighting and / or fans on or off.

[0005] 3. In order to meet the emergency use needs of the owners, a special switch is installed in the switch box. When the special switch is switched to the open state, the elevator will no longer serve the call for the elevator from the passenger side, but will only be used to serve the floor selection inside the elevator car, such as the operating elevator in the hospital.

[0006] 4. In order to meet the needs of owners to actively control the operation of the elevator, a driver switch is installed in the switch box. When the switch is switched to the on state, the driver can operate the elevator.

[0007] Chinese invention patent CN105460716B provides a method and system for setting floor addresses on elevator external call panels. The method includes: the elevator main control board is triggered by a function code to enter a fully automatic or semi-automatic setting mode for external call panel addresses; in the fully automatic setting mode, the elevator main control board assigns floor values ​​to the external call panels sequentially based on the physical floor values ​​according to the access order of the external call panels; in the semi-automatic setting mode, the elevator main control board controls the elevator to run to any floor and open the elevator door according to the received in-car instructions, and assigns floor values ​​to the external call panels of the front door and / or rear door based on the current physical location of the car and whether the rear door light curtain signal is valid according to the received preset instructions of the external call buttons; the elevator main control board is triggered by a function code to exit the fully automatic or semi-automatic setting mode for external call panel addresses. Although this solution does not increase the cost of shaft wiring, the instruction input method of this solution is relatively complex.

[0008] Therefore, the present invention provides an operation car operation command input device and method for implementing different control functions using the operation logic of existing light curtain door protection devices. Summary of the Invention

[0009] In view of the problems mentioned in the background art above, the purpose of the present invention is to provide an operation car operation command input device and method, which simplifies the control circuit involved in the operation box and its switch, reduces the manufacturing cost, and the operation command input device and method utilize the operation logic of existing light curtain door protection devices to realize different control functions.

[0010] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0011] An elevator car operation command input device and method, comprising a light curtain door protection device, a car control box, and an elevator control system;

[0012] The light curtain door protection device includes a light curtain transmitter and a light curtain receiver. The light curtain transmitter and the light curtain receiver are each composed of two protection areas: an upper zone light curtain and a lower zone light curtain. The upper zone light curtain and the lower zone light curtain each output light curtain signals to the elevator control system.

[0013] The car control panel is equipped with control buttons, door opening buttons, door closing buttons, and a digital display panel.

[0014] The elevator control system includes a main control board.

[0015] A method for inputting car operation commands, wherein the elevator control system sets the control function of the car control box to multiple function modes, the function modes including M0, M1, M2, M3 and M4, wherein M0 is the normal elevator operation mode, M1 is the car maintenance operation mode, M2 is the car driver operation mode, M3 is the car lighting control and M4 is the car fan control.

[0016] Further details are provided regarding how the elevator enters the function mode selection state, including the following steps:

[0017] S1: With the elevator door open, press the open and close buttons on the car control panel simultaneously for several seconds. The elevator will enter the car light curtain command input control state, and the digital display panel will flash the character "S".

[0018] S2: The operator first covers the upper zone multiple times with their hand, then covers the lower zone multiple times to confirm the authorization of the light curtain command input control status setting;

[0019] S3: After authorization confirmation, the elevator control system enters the mode selection state. The default initial state is the normal operation mode, and the digital display panel of the car control box flashes the character "M0".

[0020] Further specified, the duration of pressing the open and close buttons on the car control panel in S1 is 1 second.

[0021] Further specifying, in S2, the operator uses their hand to cover the upper partition three times at a frequency of 1 time / second, and then covers the lower partition three times to confirm the setting authorization of the light curtain command input control state.

[0022] Further, it also includes a method for switching elevator function modes, wherein the method includes: the operator uses their hand to block the lower partition light curtain and the upper partition light curtain from bottom to top in turn, and the elevator function mode switches to the previous mode.

[0023] Further specifying, the method for switching the elevator function mode includes: the operator uses their hand to block the upper partition light curtain and the lower partition light curtain from top to bottom in turn, and the elevator function mode switches to the next mode.

[0024] Further, it also includes a method for determining the elevator's functional mode: if the operator simultaneously blocks the upper and lower zone light curtains, then the signals of both zone light curtains are valid simultaneously, and the elevator control system determines that the signal is a confirmation of the functional mode setting.

[0025] Further specifying, the digital display panel is fixed to display the set function mode characters.

[0026] Further, it also includes a method for exiting the elevator function setting mode: after the staff has set the elevator function mode, they can exit the elevator function setting mode by pressing the door close button.

[0027] The beneficial effects of this invention are:

[0028] The existing elevator car control box has multiple physical switches that control the opening or closing of related equipment, which makes the structure of the elevator car control box relatively complex. The control circuits involved in its physical switches are also relatively complex, resulting in high manufacturing costs.

[0029] This solution provides an input device and method for operating elevator car commands. It incorporates a light curtain door protection device, a car control box, and an elevator control system. The light curtain door protection device is further divided into upper and lower light curtain sections. The elevator control system can set the control functions of the car control box to different modes, such as entering elevator function setting mode, authorization confirmation, switching to the previous mode, switching to the next mode, and exiting elevator function setting mode. Switching between these modes is achieved by the operator blocking the output signals of the upper and lower light curtain sections of the light curtain door protection device, and then using different combination logic judgments as input commands for different elevator control functions. Compared to the complex control circuits and physical switches of existing technologies, this solution simplifies the control circuits involved in the control box and its switches, reduces manufacturing costs, and provides convenient and efficient operation. It also prevents misoperation by non-professionals. Attached Figure Description

[0037] like Figure 1 and Figure 2 As shown, the present invention provides an elevator car operation command input device and method, including a light curtain door protection device 101, an elevator car control box 102, and an elevator control system 103.

[0038] The light curtain door protection device 101 includes a light curtain transmitter 104 and a light curtain receiver 105. The light curtain transmitter 104 and the light curtain receiver 105 are respectively composed of two protection areas: an upper partition light curtain 106 and a lower partition light curtain 107. The upper partition light curtain 106 and the lower partition light curtain 107 respectively output light curtain signals to the elevator control system 103.

[0039] The car control panel 102 is equipped with control buttons 108, door opening buttons 109, door closing buttons 110, and a digital display panel 111.

[0040] The elevator control system 103 includes a main control board 112.

[0041] A method for inputting car operation commands, wherein the elevator control system 103 sets the control function of the car control box 102 to multiple function modes, the function modes including M0, M1, M2, M3 and M4, wherein M0 is the normal elevator operation mode, M1 is the car maintenance operation mode, M2 is the car driver operation mode, M3 is the car lighting control and M4 is the car fan control.

[0042] In this embodiment, the elevator enters the function mode selection state, including the following steps:

[0043] S1: With the elevator door open, press the open door button 109 and the close door button 110 of the car control panel 102 simultaneously for several seconds. The elevator will enter the car light curtain command input control state, and the digital display panel 111 will flash the character "S".

[0044] S2: The operator first covers the upper zone multiple times with their hand, then covers the lower zone multiple times to confirm the authorization of the light curtain command input control status setting;

[0045] S3: After authorization confirmation, the elevator control system 103 enters the mode selection state. The default initial state is the normal operation mode, and the digital display panel 111 of the car control box 102 flashes the character "M0".

[0046] In this embodiment, the duration of pressing the door open button 109 and door close button 110 of the car control box 102 in S1 is 1 second.

[0047] In the application of this embodiment, the operator in S2 uses his hand to cover the upper partition 3 times at a frequency of 1 time / second, and then covers the lower partition 3 times to confirm the setting authorization of the light curtain command input control state.

[0048] In this embodiment, the method for switching elevator function modes is also included. The method for switching elevator function modes includes: the operator uses his hand to block the lower partition light curtain 107 and the upper partition light curtain 106 from bottom to top, and the elevator function mode is switched to the previous mode.

[0049] In this embodiment, the method for switching the elevator function mode includes: the operator uses their hand to block the upper partition light curtain 106 and the lower partition light curtain 107 from top to bottom, and the elevator function mode switches to the next mode.

[0050] In this embodiment, the method for determining the elevator function mode is also included: if the operator simultaneously blocks the upper and lower partition light curtains 107, the signals of the two partition light curtains are valid at the same time, and the elevator control system 103 determines that the signal is a function mode setting confirmation.

[0051] In this embodiment, the digital display panel 111 displays the set function mode characters.

[0052] In this embodiment, a method for exiting the elevator function setting mode is also included: after the staff has set the elevator function mode, they can exit the elevator function setting mode by pressing the door closing button 110.

[0053] As an example of this embodiment, the elevator control system 103 has a total of 9 function modes, namely M0, M1, M2, M3, M4, M5, M6, M7, M8 and M9. When the operator uses his hand to cover the lower partition light curtain 107 and the upper partition light curtain 106 from bottom to top, the elevator function mode can be switched from M0 to M9. Similarly, the digital display panel of the car control box 102 changes from flashing the character "M0" to "M9". When the operator then uses his hand to cover the upper partition light curtain 106 and the lower partition light curtain 107 from top to bottom, the elevator function mode M0 changes to M1. The digital display panel of the car control box 102 changes from flashing the character "M0" to "M1". When the operator covers the upper partition light curtain 106 and the lower partition light curtain 107 at the same time, the function mode setting is confirmed, and the digital display panel displays the set function mode character "M1".

[0054] After entering the function mode setting, there are sub-function selections in this function mode, such as on / off operation selections. The same method is used to switch options by blocking the upper and lower partition light curtains in sequence, and to confirm the settings by blocking the upper and lower partition light curtains at the same time. After the settings are confirmed, it will automatically return to the previous function setting mode.

[0055] The functional modes are shown in the table below:

[0056]
