Description

  The present invention relates to an elevator display device for displaying a failure location and a failure state when a failure occurs.

  Normally, when some failure occurs in an elevator, an error code indicating the failure location or failure state is recorded as a failure history in the main controller. Maintenance personnel who have arrived at the site after receiving notification of the failure generally connect the maintenance terminal of their own to the main control unit, confirm the above error code on the terminal screen, and perform recovery work. .

  In addition, as a method of displaying the failure status, a connection terminal to the main control device is provided at the hall, and a maintenance terminal carried by a maintenance worker is connected to the connection terminal at the hall so that the error code can be transmitted from the main control device. There is a method for performing failure analysis by taking out the error (for example, see Patent Document 1) and a method for displaying an error code at the time of failure on a display device installed at a landing (for example, see Patent Document 2). An error code is displayed.

  However, in the method of displaying an error code on the maintenance terminal as described in Patent Document 1, a maintenance terminal is necessary when a failure occurs, and it may take time to connect the maintenance terminal, and the response may be delayed.

  Further, even if an error code is displayed at a place other than the maintenance terminal as in Patent Document 2, there is a problem that cannot be dealt with unless the meaning of the error code is accurately grasped. In this case, if you are an experienced maintenance person with a long experience in maintenance inspection, you can immediately determine what kind of recovery work should be done from the displayed error code, but if you are an inexperienced inexperienced maintenance person There is a problem that the error code is not known and the recovery work is delayed by examining the instruction manual.

  The present invention has been made in view of the above points, and when any failure occurs, a maintenance terminal is not required, and the failure state at that time can be easily grasped to perform a quick and appropriate recovery operation. An object of the present invention is to provide a display device for an elevator that can be used.

  The elevator display device according to the present invention includes an error code transmission request means for requesting the main control device to transmit an error code when a failure occurs, various error codes and specific failure states indicated by these error codes in advance. Storage means for storing display data for visualizing the failure location, and the storage means when receiving an error code transmitted from the main controller in response to a transmission request by the error code transmission request means And a control means for reading out display data corresponding to the error code and displaying it at a predetermined location.

  According to the present invention, when a failure occurs, a specific failure state or failure point indicated by the error code is displayed in detail at a predetermined place such as a landing, instead of being displayed by an error code. Therefore, without requiring a maintenance terminal, the failure state at that time can be easily grasped and a quick and appropriate recovery operation can be performed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a configuration of an elevator display device according to an embodiment of the present invention. Here, the explanation is based on the premise that the failure analysis of the elevator is performed at the landing on a certain floor, but it can be realized by using the same configuration also in the platform, the landing on another floor, and the monitoring room. It is.

  The main control device 11 is installed, for example, in a machine room of a building and performs operation control of the entire elevator. A hall display device 13 is connected to the main control device 11 via a transmission cable 12. As shown in FIG. 2, the hall display device 13 is installed, for example, near the door 31 in the elevator hall 30. In the figure, 32 is a hall call button for registering a hall call.

  The hall display device 13 displays a failure location and a failure state by a predetermined operation when a failure occurs in addition to general displays such as a floor display, a direction display, and a message display in a normal state. Used.

  In the present embodiment, the hall display device 13 includes a display control unit 14, a display unit 15, a general display image data storage memory 16, and a failure display image data storage memory 17. The “image data” here includes characters in addition to symbols, figures, pictures, and the like.

  The display control unit 14 performs display control of image data on the display unit 15. The display unit 15 is composed of, for example, an LCD (Liquid Crystal Display), and performs high-quality image display. As shown in FIG. 2, the display unit 15 is disposed at a place that is easily visible on the landing 30.

  The general display image data storage memory 16 is a memory that stores image data for general display. As the general display image data storage memory 16, a non-volatile memory such as a flash ROM is used. The general display image data storage memory 16 may have a configuration built in the display control unit 14 or a configuration that can be inserted and removed like a memory card.

  The failure display image data storage memory 17 is a memory that stores image data for general display. Like the general display image data storage memory 16, the failure display image data storage memory 17 includes a nonvolatile memory such as a flash ROM. The failure display image data storage memory 17 is configured to be insertable / removable like a memory card. This is because it is assumed that an additional failure display pattern will appear in the future due to the advancement of elevator models. Even if the failure display image data storage memory 17 is built in the display control unit 14, there is no particular problem in realizing the present invention.

  In the example of FIG. 1, the general display image data storage memory 16 and the failure display image data storage memory 17 are provided separately, but may be configured by one nonvolatile memory.

  The display control unit 14 includes a transmission control CPU 21, a display driver 22, an error code transmission request switch 23, an inspection switch 24, and a password input unit 25.

  The transmission control CPU 21 performs communication with the main control device 11, and when display code data is sent from the main control device 11, the general display image data storage memory 16 or the failure display image data storage. The corresponding display data is read from the memory 17 and displayed on the display unit 15 via the display driver 22. The display driver 22 is a driver for driving the display unit 15.

  The error code transmission request switch 23 is a switch for requesting the main control device 11 to transmit an error code when a failure occurs.

  The inspection switch 24 is a switch for switching the operation mode of the elevator to the inspection mode. The transmission control CPU 21 detects the state of the inspection switch 24, and if it is not in the inspection mode, that is, in the normal operation mode, even if an error code is received from the main controller 11, the floor display, direction display, and message display are continued. General display processing such as is performed.

  The password input unit 25 is for preventing a person other than a registered maintenance person from performing a fault display, and is configured by installing four rotary switches that can set hexadecimal codes of 0 to F, for example. Is done.

  The failure display is permitted only when the password input from the password input unit 25 matches the password preset in the transmission control CPU 21. As a result, only maintenance personnel who know the password can display the failure, preventing a third party such as an ordinary person using the elevator from performing the failure display without permission. In addition to the maintenance staff, it is also possible to notify the building manager of the password.

  FIG. 3 is a diagram showing the configuration of the general display image data storage memory 16 provided in the hall display device 13.

  The general display image data storage memory 16 stores floor display data 41, direction display data 42, and information display data 43.

  The floor display data 41 includes general floor display data such as first floor display data, second floor display data,... N floor display data, B1 floor display data, R floor display data, home floor display data, and ticket gate floor display data. , It consists of special floor display data such as parking floor display data. By storing the display data of the floor at the address corresponding to the floor code received from the main control device 11, the display of each floor can be realized.

  The direction display data 42 is composed of ascending display data and descending display data. Data for displaying the up arrow mark as the ascending display data and the down arrow mark as the descending display data are used.

  The information display data 43 includes message data 1, message data 2,... Message data n. Specifically, for example, message data for control operation such as “earthquake”, “fire”, “power failure”, etc., for alerting during operation such as “door closes”, “please be careful with your feet” Message data, general message data such as “Today is a garbage collection date”, “Good morning”, etc. Further, the information display data 43 includes message data for notifying a communication abnormal state.

  FIG. 4 is a diagram showing a configuration of the failure display image data storage memory 17 provided in the hall display device 13.

  The failure display image data storage memory 17 stores header information 51, a model a data table 52, a model b data table 53,..., A model n data table 54, and the like. Here, since there is usually a failure specific to each model, the failure display image data storage memory 17 performs data management for each model.

  The header information 51 includes a password identification code. The password identification code and the password code input from the password input unit 25 are collated, and if they do not match, failure display is prohibited.

Data table 52 of the type a, the elevator model code a, the error code a _1, the display image data a _1, error code a _2, display image data a _2, ... error code a _n, composed of a display image data a _n.

The elevator model code a and the error codes a _{1 to n} are code data sent from the main controller 11 in response to a failure when a failure occurs. The elevator model code a is an identification code of the model a, and an error code a _{1 to n} is a coded failure location and failure status. The display image data a _{1 to n} are stored in association with the error codes a _{1 to n} , and are data for visualizing and displaying specific failure locations and failure states.

  The model b data table 53 and the model n data table 54 have the same configuration as the model a data table 52.

  Next, a communication format of data transmitted from the main control device 11 to the hall display device 13 will be described with reference to FIGS. 5 and 6.

  FIG. 5 is a diagram showing an example of a communication format when the main controller 11 transmits a model code.

  When the main control device 11 transmits the model code, the transmission address 61 and the model code transmission notice data 62 are transmitted twice, and then the transmission address 61 and the model code data 63 are transmitted in this order.

  The transmission address 61 is a device-specific address assigned in advance to the hall display device 13. The model code transmission notice data 62 is data for notifying that the data to be transmitted is a model code. The model code data 63 is code data indicating the elevator model of the main control device 11.

  FIG. 6 is a diagram illustrating an example of a communication format when the main control device 11 transmits an error code.

  Even when the main control device 11 transmits an error code, the transmission address 61 and the error code transmission notice data 64 are repeated twice, and then the transmission address 61 and the error code data 65 are transmitted in this order.

  The error code transmission notice data 64 is data for notifying that the data to be transmitted is data different from the data used for general display. The error code data 65 is code data stored as a failure history in the main controller 11 when a failure occurs.

  In such a configuration, when some failure occurs, the failure code is displayed by operating the error code transmission request switch 23. The error code transmission request signal transmitted by operating the error code transmission request switch 23 is validated only when the password code input from the password input unit 25 matches the password identification code of the header information 51.

  The main control device 11 transmits only the general display data to the hall display device 13 when the error code transmission request signal is not received. On the other hand, when receiving the error code transmission request signal, the main control device 11 transmits an error code indicating the failure location and the failure state to the hall display device 13 according to a predetermined communication format together with the code of the model in which the failure has occurred. In response to this, the hall display device 13 displays a failure. In this case, the error code is not displayed as it is, but a specific failure location or failure state indicated by the error code is displayed in an easy-to-understand manner with an image (including a text message).

FIG. 7 shows a display example of the hall display device 13.
Here, a display example when a car door abnormality occurs is shown. By displaying the abnormal location and the failure state specifically, the maintenance staff can immediately analyze the cause of the failure and take action.

  The operation of the embodiment will be described in detail below.

  FIG. 8 is a flowchart showing operations of the general display process and the failure display process of the hall display device 13.

  When the transmission control CPU 21 provided in the hall display device 13 receives its own address (transmission address assigned to the hall display device 13) from the main control device 11 (step S101), the next received data is a model code transmission advance notice. It is determined whether it is data (step S102).

  When data other than the model code transmission advance notice data is received (No in step S102), the transmission control CPU 21 reads general display data corresponding to the received data from the general display image data storage memory 16 (step S103). The general display data is displayed and output on the display unit 15 (step S114). As a result, the floor, driving direction, message, and the like that the car is currently driving are displayed.

On the other hand, when the model code transmission advance notice data is received (Yes in step S20), the transmission control CPU 21 determines whether or not the next received data is the second model code send advance notice data (step S104). )
If the second model code transmission advance notice data cannot be received (Yes in step S104), it means that data different from the communication format described above (see FIG. 5) has been received. In such a case, the transmission control CPU 21 determines that a communication abnormality has occurred, reads out the communication abnormality display data from the general display image data storage memory 16 (step S105), and displays the communication abnormality display data. Display output on the unit 15 (step S114)
In this embodiment, the example in which the model code notice data is read twice is described. However, if the display responsiveness is not hindered, the same is repeated several times in order to improve the communication quality. It may be confirmed. Further, the communication abnormality display data is read from the failure display image data storage memory 17, but it may be fixed data built in the program of the transmission control CPU 21.

On the other hand, when the second model code transmission notice data is received (Yes in step S104), the transmission control CPU 21 receives the model code sent subsequently (step S106), and receives the received model code. It is determined whether the selected model code exists in the failure display image data storage memory 17 (step S107).
If there is no corresponding model code (No in step S107), the transmission control CPU 21 warns that there is no model code such as “There is no model code corresponding to the memory card. Replace the memory card.” Is read from the general display image data storage memory 16 (step S108) and displayed on the display unit 15 (step S114).

  The warning display data may be fixed data built in the program of the transmission control CPU 21 or may be stored in the failure display image data storage memory 17.

  If there is a corresponding model code (Yes in step S107), the transmission control CPU 21 determines whether or not the next received data is error code transmission notice data (step S109).

If the error code transmission advance notice data cannot be received (No in step S109), data different from the communication format described above (see FIG. 6) has been received. Therefore, the transmission control CPU 21 causes a communication abnormality to occur. The communication abnormality display data is read from the general display image data storage memory 16 (step S110) and displayed on the display unit 15 (step S114).
When the error code transmission advance notice data is received (Yes in step S109), the transmission control CPU 21 determines whether the next received data is the second error code transmission advance notice data (step S111). ).

  If the second error code transmission advance notice data cannot be received (No in step S111), data different from the communication format (see FIG. 6) has been received as described above. Therefore, the communication abnormality display data is read from the general display image data storage memory 16 (step S110) and displayed on the display unit 15 (step S114).

  On the other hand, when the second error code transmission notice data is received (Yes in step S111), the data received next becomes error code data (step S112). Upon receiving this error code data, the transmission control CPU 21 accesses the failure display image data storage memory 17 and reads the display data of the corresponding failure information from the model code data and the error code data (step S113). , Display output on the display unit 15. (Step S114). As a result, the location or state where the failure occurred is displayed in detail.

  Note that the error code notice data is read twice as in the case of the above model code. However, if the display responsiveness is not hindered, a plurality of times will be added to improve the communication quality. The same confirmation may be performed.

  By the way, for example, when the transmission cable 12 connecting the main control device 11 and the hall display device 13 is physically disconnected, an error code cannot be sent from the main control device 11 to the hall display device 13. Failure indication cannot be performed.

Hereinafter, the display processing operation in such a communication abnormality state will be described.
FIG. 9 is a flowchart showing the operation of the communication abnormality display process by the hall display device 13.

  By operating the error code transmission request switch 23 and the password input unit 25, an error code transmission request signal is transmitted from the transmission control CPU 21 provided in the display control unit 14 to the main control device 11 (step S201).

  At that time, the transmission control CPU 21 sets a reception waiting time of its own address (step S202). If it is within the set time (No in step S202), the transmission control CPU 21 periodically monitors the data sent from the main control device 11 and determines its own address (transmission address assigned to the hall display device 13). It is determined whether or not it has been received (step S203). When the own address is received (Yes in step S203), the transmission control CPU 21 follows the image display processing procedure described in FIG. 8 and based on the data received from the main control device 11, the general display image data storage memory 16 Alternatively, the corresponding display data is read from the failure display image data storage memory 17 and displayed on the general display image data storage memory 16 (step S204).

If the own address cannot be received (No in step S203), the transmission control CPU 21 determines whether or not the own address reception waiting time exceeds the set time (step S202). Here, when the set time is exceeded without receiving the address itself (Yes in step S202), the transmission control CPU 21 determines that a communication abnormality due to disconnection or the like has occurred, and the general display image Communication abnormality display data is read from the data storage memory 16 (step S205) and displayed on the display unit 15 (step S206).
In addition, after displaying a communication abnormality, it is assumed to be in a reception waiting state for its own address (step S203). This is because failure display can be performed when the communication state is restored, and it is possible to confirm in real time that the communication state has been restored by using this as a trigger.

  As described above, by preparing data for displaying a specific failure corresponding to various error codes in advance, when any failure occurs, it is not a simple code display such as an error code. It is possible to display a message such as “Control device motor failure. Replace the motor connection cable.” As a result, even a maintenance person unfamiliar with the inspection can easily perform quick and appropriate recovery work from the displayed contents.

  In addition, since such a failure display is performed through a display device installed at the hall, it is possible to restore by eliminating the trouble of having a maintenance terminal and connecting to a control device etc. Work efficiency can be improved.

  In the above embodiment, a display device installed on a floor of a certain floor has been described as an example. However, as a place of installation of the display device, not only on the floor of other floors, but also in a car or monitoring. Any place such as a room that can be easily seen by maintenance personnel when performing maintenance inspections may be used.

  In addition, as a method for authenticating maintenance personnel who are permitted to send an error code, a password has been described as an example. However, for example, a method of reading an authentication card or a method of authenticating using a voice print, a fingerprint, or the like. May be.

  In short, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
