Description

Technical Field

[0001] The present invention belongs to the technical field of elevator control, and particularly relates to a portable dual-mode elevator control device and system. Background Art

[0002] With the advent of the era of large-scale logistics in China, modern warehousing management has extremely high requirements for the efficiency and safety of material transfer, and the elevator system plays a crucial role in this process. However, there are many deficiencies in the traditional elevator control method in meeting the above requirements. On the one hand, it often causes the elevator to be called and occupied by other floors, thus reducing the usage opportunities of the floors where materials need to be transferred. Especially during the high-frequency material transfer process, the elevator is frequently occupied by other floors, resulting in a waste of elevator resources and a reduction in transfer efficiency. On the other hand, during the material transfer process, the elevator car door may automatically close due to time settings, which poses a serious safety hazard to the operators.

[0003] To solve the above technical problems, a dual operating mode is usually set for the elevator. The dual mode of the elevator refers to the conventional control mode and the centralized control mode. The conventional control mode is the mode for daily elevator use. In this mode, anyone on each floor can summon the elevator through the up and down buttons set in each elevator hall. The elevator automatically responds to the elevator call application, automatically opens the elevator door when it reaches the summoned floor. After a person enters the elevator car, they can select the destination floor by themselves. The person closes the door by pressing the door closing button or the door automatically closes after a set time when the person enters the elevator. After the elevator detects the door closed in-place signal, the elevator starts to run to the destination floor. The centralized control mode is the mode used in special scenarios, such as scenarios where a large amount of materials need to be transferred to a specific floor or a large number of people need to be transported to a specific floor. There is an interlock relationship between the conventional control mode and the centralized control mode. When one mode is selected, the other mode will become invalid. Usually, a mode switching device is set up for the management personnel to switch the mode according to actual needs.

[0004] Japanese Patent Application Publication No. JP2014076889A discloses an elevator control system, which includes an elevator. Inside the elevator, there is a normal operation panel for daily commuting and a special operation panel for special operations, such as carrying luggage. The system also has a special operation start button and a door opening button at the elevator entrance on each floor. On the special operation panel inside the elevator, there are floor selection buttons and mode switching buttons. When luggage transfer is needed, the daily mode is switched to the special mode through the mode switching button inside the elevator, and then the daily mode becomes invalid. The special operation panel inside the elevator and the start buttons and door opening buttons set at the elevator entrances on each floor are used to achieve efficient luggage transfer. Although this system solves the problem of low material transfer efficiency to a certain extent, there are the following problems: 1) Since the mode switching button is set inside the elevator, it can be accessed by any person. During daily commuting, some people may privately switch to the special mode in order to reach their destination floors as soon as possible for themselves, thus affecting the normal commuting of other people; moreover, during the material transfer process, if it is privately switched to the daily mode by other people, it will also affect the transfer efficiency of materials; 2) Since such a special operation panel needs to be installed in each elevator car, and operation panels with start buttons and door closing buttons also need to be installed in the elevator lobbies on each floor to achieve dual-mode control, it is necessary to modify the operation areas of each existing elevator car and the elevator lobbies on each floor, with a high cost and poor practicability. Summary of the Invention

[0005] The object of the present invention is to provide a portable dual-mode elevator control device and system to solve the problems that the existing dual-mode elevator control method is easily interfered during material transfer or daily operation and has a high cost.

[0006] The portable dual-mode elevator control device provided by the present invention to solve the above technical problems includes a processor, a communication expansion module, an I / O expansion module, and a main control panel. The processor is connected to the main control panel through the I / O expansion module. The processor is used to connect to the elevator controller through the communication expansion module to obtain elevator status information and transmit the operation information of the main control panel to the elevator controller; on the main control panel, there are a mode switching switch and floor selection buttons. The mode switching switch is used to switch the elevator operation mode, and the elevator operation mode includes a centralized control mode and a conventional control mode. The floor selection buttons on the main control panel are only valid in the centralized control mode.

[0007] Furthermore, in the centralized control mode, the processor is used to receive elevator call requests from the outer hall operation areas on each floor of the elevator lobby and respond to the elevator call requests according to the operation conditions of the elevator in the centralized control mode.

[0008] Further, in the centralized control mode, if the summoned floor is between the current position of the elevator and the destination floor where the elevator is currently moving, the processor responds to the elevator call application and assigns operation permissions to the in-car operation area inside the car: only the corresponding floor selection buttons between the summoned floor and the destination floor where the elevator is currently moving are effective.

[0009] Further, the main control panel further includes an open door button and a close door button, and the open door button and the close door button are only effective in the centralized control mode.

[0010] Further, in the centralized control mode, if the elevator car door is opened, the elevator car door closes only when the elevator receives a door closing instruction from the main control panel, the out-car operation area on the floor elevator hall, or the in-car operation area inside the car, otherwise it remains in the current state.

[0011] The dual-mode elevator control system provided by the present invention to solve the above technical problems includes an in-car operation area provided inside the elevator car and an out-car operation area provided in each floor elevator hall. The in-car operation area includes floor selection buttons, an open door button, and a close door button; the out-car operation area includes an up button and a down button. The system further includes a portable dual-mode elevator control device. The portable dual-mode elevator control device includes a processor, a communication expansion module, an I / O expansion module, and a main control panel. The processor is connected to the main control panel through the I / O expansion module. The processor is used to connect to the elevator controller through the communication expansion module, for obtaining elevator status information and transmitting the operation information of the main control panel to the elevator controller; the main control panel is provided with a mode switch and floor selection buttons; the mode switch is used to switch the elevator operation mode, and the elevator operation mode includes a centralized control mode and a conventional control mode. The floor selection buttons on the main control panel are only effective in the centralized control mode.

[0012] Further, the up button and the down button have an elevator call function in the centralized control mode. The elevator call function means that when the up button and / or the down button is pressed, an elevator call application is sent to the portable elevator control device. The processor of the portable elevator control device receives the elevator call application and responds to the elevator call application according to the operation situation of the elevator in the centralized control mode.

[0013] Further, in the centralized control mode, if the summoned floor is between the current position of the elevator and the destination floor where the elevator is currently moving, the processor responds to the elevator call application and assigns operation permissions to the in-car operation area: only the corresponding floor selection buttons between the summoned floor and the destination floor where the elevator is currently moving are effective.

[0014] Further, the main control panel further includes an opening button and a closing button, and the opening button and the closing button are only effective in the centralized control mode.

[0015] Further, in the centralized control mode, when the up button and the down button in the outer hall operation area are pressed simultaneously, if the car door is in the closed state, the elevator performs an opening action, and if the car door is in the open state, the elevator performs a closing action.

[0016] The beneficial effects of the control device and system of the present invention are as follows: 1) Instead of setting the control device for realizing dual-mode switching and floor selection in the elevator car, it is set to be portable. This portable control device has a dedicated placement position, and only dedicated management personnel can access it. Therefore, it avoids passengers privately switching the elevator operation mode and affecting the normal use of the elevator in the current operation mode, and ensures the reliable operation of the elevator in both modes. At the same time, because the control device can be carried around, it has good compatibility and adaptability. When there are special usage requirements for the elevator, it can be quickly connected to the general elevator controller. After use, it can be put away immediately, achieving the effect of plug-and-play or connection-and-use. Therefore, when used in special scenarios such as material transfer, the control device can be carried to the material transfer site by the background management personnel or material transfer personnel for on-site operation, avoiding the problem of operation errors caused by inaccurate and untimely understanding of the on-site situation during operation in the background machine room. Therefore, the portable control device of the present invention can balance operation accuracy and the reliability of the elevator operation in both modes.

[0017] 2) Only through program settings, it is possible to realize the dual-mode control of any elevator in the whole building by combining a portable control device with the inherent controller, the in-hall operation area, and the out-of-hall operation area of a general elevator. There is no need to transform the hardware facilities inside and outside the elevator car. Only by optimizing and upgrading the original control program of the general elevator and connecting an external control box can dual-mode control be achieved, and it can be used as needed, achieving plug-and-play. This greatly saves the control cost and has strong practicability. Description of the Drawings

[0018] Figure 1 It is a schematic diagram of the main control panel of the portable dual-mode control device according to an embodiment of the present invention. Detailed Embodiments

[0019] The following further describes the detailed embodiments of the present invention with reference to the drawings.

[0020] The basic idea of the present invention is that instead of setting the control device for realizing the dual-mode switching and floor selection of the elevator in the elevator car, it is set to be portable and kept by a special person, and is only used by special management personnel. This portable control device has good compatibility and adaptability and can be quickly connected to the general elevator controller. With such a setting, on the one hand, there is no need to transform the hardware facilities inside and outside the elevator car. By only upgrading the program of the inherent elevator controller and externally connecting this control device, the whole elevator can be controlled, thus greatly reducing the control cost, and it can be carried to the operation site for plug-and-play to ensure the accuracy of operation. On the other hand, only specific operators can access this control device, and elevator passengers cannot, thus avoiding passengers privately switching the elevator operation mode and affecting the normal use of the elevator in the current operation mode.

[0021] Embodiment of the dual-mode elevator control system of the present invention Based on the above basic idea, the dual-mode elevator control system of the present invention includes an in-car operation area provided in the elevator car and an out-car operation area provided in the elevator hall on each floor. The in-car operation area includes floor selection buttons, door opening buttons and door closing buttons; the out-car operation area includes an up button and a down button. The system also includes a portable dual-mode elevator control device. The portable dual-mode elevator control device of the present invention includes a processor, a communication expansion module, an I / O expansion module and a main control panel. The processor is connected to the main control panel through the I / O expansion module. The processor is used to connect to the elevator controller through the communication expansion module, for obtaining elevator status information and transmitting the operation information of the main control panel to the elevator controller; as Figure 1 shown, a mode switching switch and floor selection buttons are provided on the main control panel. The mode switching switch is used to switch the elevator operation mode. The elevator operation mode includes a centralized control mode and a conventional control mode. The floor selection buttons on the main control panel are invalid in the conventional control mode and valid in the centralized control mode. In the centralized control mode, the elevator is controlled to reach the destination floor according to the floor selection buttons on the main control panel.

[0022] The elevator controller in this embodiment is the controller inherent in traditional elevators, that is, the controller that controls the normal operation of the elevator in the conventional control mode. There are various specific implementation methods for the processor to connect to the elevator controller through the communication extension module. For example, the communication extension module may include a wireless communication module and can communicate with the elevator controller with wireless communication function through wireless communication. Or, the communication interface of the communication extension module is connected to the elevator controller in the background through a cable. Or if there is a communication interface reserved in the elevator car or elevator hall for connection to the elevator controller, it can also be connected to this communication interface through a cable to achieve communication with the elevator controller. The communication technologies for realizing wired or wireless connection are existing ones and will not be elaborated here in detail. When the portable dual-mode elevator control device establishes communication with the elevator controller, it shares the status information of the elevator with the elevator controller, and the portable dual-mode elevator control device can control the elevator through the elevator controller.

[0023] The portable dual-mode elevator control device in this embodiment can be set as a dedicated control chassis or can be realized by means of existing mobile terminals, such as mobile phones, tablets, etc. Then, an elevator control APP needs to be installed in the mobile terminal. After logging in and opening the elevator control APP, buttons such as a floor selection button and a mode switch are displayed. It communicates with the elevator controller wirelessly through the communication module of the mobile terminal.

[0024] The control principle of the above-mentioned portable dual-mode elevator control device is as follows: After an operator (who can be a dedicated operator or a material transfer personnel) establishes communication between the portable dual-mode elevator control device and the elevator controller, the elevator operation mode is switched to the centralized control mode. At this time, the elevator is controlled through the main control panel. The operator has pre-known the specific floor to be controlled. For example, when it is necessary to transfer materials from the 1st floor to the 6th floor, if the elevator has stopped at the 1st floor, at this time the operator presses the 6th floor, which is the destination floor, on the main control panel. After the elevator stopped at the 1st floor opens, the material transfer personnel A waiting on the 1st floor carry the materials into the elevator. After the elevator door closes, the elevator starts to run to the 6th floor. After arriving at the 6th floor, the elevator door opens. The material transfer personnel B waiting on the 6th floor or the material transfer personnel A who arrives at the 6th floor together with the goods carry the goods out of the elevator. Under the control of the operator, the elevator returns to the 1st floor to pick up goods again, and so on, cycling for material transfer until the material transfer is completed. Of course, there can also be only one material transfer personnel. In this case, the material transfer personnel will be transported by the elevator together with the materials.

[0025] When transporting materials into or out of an elevator, it may be necessary to enter and exit the elevator multiple times, and the transportation process takes a relatively long time. To ensure the safety of material transfer personnel and the efficiency of material transfer, the elevator door remains open during the transportation process. To keep the elevator door open during the transportation process, it can be achieved through automatic control. For example, the opening time of the elevator door is set according to the time spent transporting materials, and the elevator door automatically closes after reaching the set time. However, there are differences in physical strength among people, and the amount of goods transported each time may also be different. These factors will affect the material transportation time. When the opening time is fixed at a certain value, it may result in the elevator door closing too early before the materials are completely transported, or the opening time being too long, and the elevator door closing some time after the materials are transported, which will waste time. Whichever situation occurs will affect the material transportation efficiency. Therefore, as a preferred implementation method, the elevator door is closed manually. That is, after the elevator door opens, it can only be closed by pressing the door closing button. If the operation instruction of the door closing button is not received, it will always remain open. The elevator door can be closed manually in the following two ways: Method 1: Set a door closing button and a door opening button on the main control panel, and use the elevator monitoring system in the background to achieve it. Specifically: After the elevator reaches the destination floor, the elevator door opens and remains open. After the background operator monitors that the material transfer personnel at the elevator have completed transporting the materials, press the door closing button, and the elevator door closes. This method requires relying on the monitoring system and the background operator to keep staring at the monitor all the time, but it can free the hands of the material transfer personnel, which will be very convenient when the material transfer requires occupying the hands of the material transfer personnel.

[0026] Furthermore, considering that when the background operator monitors that the materials have been transferred into or out of the elevator and forgets to close the elevator door and directly issues an instruction to change the floor, a reminder device is also set on the main control panel. Before the controller controls the elevator to move to the destination floor, it will detect the state of the elevator door. If the elevator door is closed, the car will start running to the target floor; if the elevator door is not closed, the reminder device on the main control board will prompt the background operator to perform a door closing operation. The reminder device is a voice reminder, such as emitting a voice "Elevator door not closed" or "Please close the elevator door". As Figure 1 shown, the reminder device can also be simply set as a buzzer, which emits a beep if the elevator door is not closed. The reminder device set on the main control panel is only effective in the centralized mode.

[0027] Method 2: In the operation area of the elevator hall on each floor, abbreviated as the outer hall operation area, there are an up button and a down button. The opening and closing of the elevator door are achieved by using the up button and the down button on the outer hall operation area. When both the up button and the down button are triggered simultaneously, the elevator door operates. The door opening and closing function of the outer hall operation area is only effective in the centralized control mode and ineffective in the conventional control mode. Specifically, when the elevator stops at the destination floor, the elevator door automatically opens and remains open. After the material transfer personnel at the elevator transfer the materials into or out of the elevator, when they press both the up button and the down button on the outer hall operation area simultaneously, the elevator door closes. Considering the situation that the material transfer personnel may take the elevator together with the materials, the opening button and the closing button on the inner hall operation area can be set to be effective in the centralized control mode, and the opening and closing of the elevator door are achieved through the opening button and the closing button on the inner hall operation area inside the elevator car. Although this method requires the material transfer personnel at the elevator to control the opening and closing of the elevator door, it does not rely on the background operator to monitor the material transfer process. The control of the elevator door opening and closing is more flexible, and the material transfer is also safer.

[0028] When the up button and the down button set on the outer hall operation area of a certain floor are pressed, it indicates that there is a need to take the elevator on this floor. In the conventional control mode, the elevator will directly respond to this demand and automatically open for people to use when it reaches the summoned floor. In the prior art, once the operation mode of the elevator is switched to the centralized control mode, the floor call buttons (up button and down button) set on the outer hall operation area inside the elevator hall are ineffective. That is, when the up button and the down button on the outer hall operation area are triggered, an elevator call application cannot be sent to the elevator controller, and thus the elevator will not move to the summoned floor. In order to be able to take into account the conventional use requirements of the elevator in the centralized control mode and further improve the use efficiency of the elevator, the present invention has improved the existing centralized control mode: in the centralized control mode of the present invention, when the up button and the down button on the outer hall operation area are triggered effectively, the elevator call application will be sent to the elevator controller. However, the centralized control mode of the present invention is different from the conventional control mode in that when the up button or the down button is pressed, the elevator controller will not directly respond and move the elevator to the summoned floor, but will transmit the elevator call application to the portable dual-mode elevator control device, informing the control device that there is a need to take the elevator on certain floors, and the control device selects an appropriate time to respond to the elevator call application according to the current operation situation, so as to send the elevator to the summoned floor through the elevator controller.

[0029] Preferably, considering the operation efficiency of the elevator in the centralized mode, the appropriate time refers to: in the centralized control mode, if the summoned floor is between the current position of the elevator and the destination floor where the elevator is currently moving, the control device responds to the elevator call application and moves the elevator to the summoned floor; otherwise, it does not respond to the elevator call application.

[0030] Under the existing centralized control mode, all floor selection buttons in the in-hall operation area are ineffective. However, in order to take into account the regular use requirements of the elevator under the centralized control mode and further improve the use efficiency of the elevator, the present invention further improves the existing centralized control mode: under the centralized control mode of the present invention, when the control device responds to an elevator call application, it assigns operation authority to the in-hall operation area, that is, makes the corresponding floor selection buttons between the called floor and the current destination floor of the elevator operation effective, while other floor selection buttons are ineffective.

[0031] Preferably, considering that there may be goods in the elevator under the elevator centralized control mode, which may result in overloading or being unfavorable to passenger safety. In this embodiment, when the control device determines whether to respond to the elevator call application, it takes into account the situation of having goods in the elevator. When there are goods in the elevator, the control device does not respond to the elevator call application.

[0032] For example, when the elevator has just transported a batch of materials and is running from the 6th floor to the current destination floor, the 1st floor, at this time, the elevator car is empty. If a person C presses the down button on the 4th floor below the 6th floor and the elevator has not passed the 4th floor yet, the control device can respond to this demand and make the elevator stop at the 4th floor where the person C is located. At this time, the floor selection buttons between the 4th floor and the 1st floor (1, 2, 3, 4) in the in-hall operation area are effective. After the person C enters the car, they can select the target floor from the effective floor selection buttons.

[0033] It should be noted that the buttons on the inherent in-hall operation area of the general elevator are all provided with background indicator lights, and the indicator lights have three states: off, dimly lit, and brightly lit. Therefore, in order to give a more user-friendly prompt to the person C about the selectable floors, the background lights of the effective floor selection buttons can be set to the dimly lit state, and the background lights of the ineffective floor selection buttons can be set to the off state. Considering that the elevator ride of the person C is an unexpected temporary task for the dispatching work under the centralized control mode, there may be a situation where the person C does not actively close the door after selecting the floor or leaving the elevator, resulting in the elevator being unable to leave and affecting the transfer efficiency. Therefore, for the floor change instruction issued through the in-hall operation area under the centralized mode, after the instruction is issued or when reaching the instruction floor, the car door adopts the control logic in the conventional control mode, that is, it automatically closes after a certain delay. When the person C gets off the elevator, the car door automatically closes, and the elevator continues to go to the destination floor for operation. In this way, it is possible to take into account the elevator ride requirements of other people during the material transfer process, making the dual-mode control method more flexible and user-friendly.

[0034] Furthermore, considering that the material transfer personnel at the elevator may forget to close the elevator door after transferring materials into or out of the elevator, for safety reasons, the voice broadcast device on the inner hall operation panel inherent in the general elevator can be used for voice prompts. After the control device receives the floor change instruction issued by the backstage operator, it will detect the state of the elevator door. If the elevator door is closed, the elevator will start running to the target floor; if the elevator door is not closed, the voice broadcast device set on the inner hall operation area will prompt the material transfer personnel to perform the door closing operation.

[0035] Furthermore, the floor selection buttons on the main control panel are buttons with indicators. These buttons have the functions of floor status display and instruction input. When the selection button corresponding to the destination floor is pressed, the selection button corresponding to the destination floor blinks. When the elevator reaches the destination floor, the selection button corresponding to the destination floor changes from blinking to constantly on. When the elevator leaves the destination floor, the selection button corresponding to the destination floor will go out as the elevator leaves. For example, when the current elevator stops at the 3rd floor, the selection button corresponding to the 3rd floor is constantly on. At this time, if the 5th floor selection button is pressed, the selection button corresponding to the 5th floor blinks. When the elevator runs to the 5th floor, the selection button corresponding to the 5th floor changes from blinking to constantly on, and the selection button corresponding to the 3rd floor will go out as the elevator leaves.

[0036] Preferably, the door opening and closing buttons set on the main control panel are buttons with indicators. The door opening and closing indicators are used to display the current state of the elevator door. When the door opening or closing is in place, the corresponding indicator is constantly on; during the door opening and closing process, the corresponding indicator blinks. Through the display of the door opening and closing status, it helps the operator understand the operation status of the elevator at the stopped floor.

[0037] Preferably, the door opening and closing buttons on the inner hall operation area are lighted buttons. When the door opening and closing buttons are pressed, they are constantly on, and the elevator door performs the corresponding actions. After the elevator door performs the actions in place, the door opening and closing buttons go out.

[0038] Preferably, the floor call buttons on the outer hall operation area, namely the up button and the down button, are lighted buttons. When a certain floor call button is pressed, it is constantly on. When the elevator reaches that floor, the corresponding floor call button goes out.

[0039] Embodiment of the portable dual-mode elevator control device of the present invention The portable dual-mode elevator control device of the present invention includes a processor, a communication expansion module, an I / O expansion module, and a main control panel. The processor is connected to the main control panel through the I / O expansion module. The processor is used to connect to the elevator controller through the communication expansion module, obtain elevator status information, and transmit the operation information of the main control panel to the elevator controller. A mode switch and floor selection buttons are provided on the main control panel. The mode switch is used to switch the elevator operation mode, and the elevator operation mode includes a centralized control mode and a conventional control mode. The floor selection buttons on the main control panel are only valid in the centralized control mode.

[0040] For the further settings of the portable dual-mode elevator control device, refer to the elevator control device in the above-mentioned dual-mode elevator control system, which will not be elaborated here.

[0041] In summary, the characteristics of the control device and system of the present invention are as follows: 1) Instead of setting the control device for realizing dual-mode switching and floor selection in the elevator car, it is set as a portable one, and this portable control device has a dedicated placement location, and only specialized management personnel can access it. Therefore, it avoids passengers privately switching the elevator operation mode and affecting the normal use of the elevator in the current operation mode, ensuring the reliable operation of the elevator in both modes. At the same time, because the control device can be carried around and has good compatibility and adaptability, when there are special usage requirements for the elevator, it can be quickly connected to the general elevator controller. After use, it can be put away immediately, achieving the effect of plug-and-play and connecting-and-using at any time. Therefore, when used in special scenarios such as material transfer, the control device can be carried by the back-end management personnel or material transfer personnel to the material transfer site, quickly connected to the elevator controller, and operated on-site, avoiding the problem of operation errors caused by inaccurate and untimely understanding of the on-site situation when operating in the back-end machine room. Therefore, the portable control device of the present invention can balance the operation accuracy and the reliability of the elevator operation in both modes.

[0042] 2) Only through program settings, it is possible to complete the dual-mode control of any elevator in the whole building by combining a portable control device with the inherent controller, in-hall operation area, and out-of-hall operation area of a general elevator. There is no need to transform the hardware facilities inside and outside the elevator car. Only by optimizing and upgrading the original control program of the general elevator, it is possible to achieve dual-mode control by externally connecting a control box, and it can be plugged and used as needed, greatly saving the control cost and having strong practicability.

[0043] 3) In the centralized control mode, the floor call buttons on the outer hall operation area are not completely ineffective. They can still send elevator call requests to the background. An intelligent scheduling algorithm is introduced into the control device to meet the requirements of the conventional control mode in the centralized control mode, further improving the elevator usage efficiency and making the dual-mode control more flexible and user-friendly.

[0044] 4) In the centralized control mode, the personnel on the operating floor or the background operators are allowed to actively control the elevator doors, improving the operation safety.
