Description

  The present invention relates to an elevator maintenance information guide device for guiding and displaying information related to elevator maintenance to a user.

  Elevator inspection date, inspection time, etc. are notified to the user only by the building manager receiving notification from the elevator maintenance company, using the bulletin board and sticker on each floor, and providing the user with the inspection date, inspection time, etc. The method of notifying is taken.

  However, notifications using bulletin boards and stickers can be used to know the date of inspection if the user is looking at the bulletin board or sticker every day. Is often overlooked. As a result, for example, in the case of a building where one elevator is installed, or a building where a plurality of elevators are installed at distances, raising and lowering of non-healthy people and relatively old users It becomes difficult to move, and a heavy burden is placed on users with heavy loads.

In view of this, an elevator information guidance device has been proposed that displays the elevator inspection date and the inspection end time during maintenance work in advance. When the inspection date approaches, the elevator information guide device transmits information on the inspection date and time from the central monitoring center to the elevator control device of the corresponding building. The elevator control device displays the received inspection date information on a hall display device installed at the hall of each floor. Further, when the maintenance staff is heading to the site, the maintenance end time information or the maintenance start time information is transmitted from the central monitoring center to the elevator control device of the corresponding building. Here, the elevator control device displays maintenance end time information or maintenance start time information on the hall display device as described above (Patent Document 1).

  However, all of the elevator information guidance devices as described above generally transmit information related to maintenance from the central monitoring center and display the information on the hall display device at each floor hall. As a result, it is possible to inform the user in advance of the inspection date and time, etc., but when the elevator control device receives the inspection date and time etc., it will be displayed on the landing display device immediately, so the inspection date and time information etc. in advance according to the maintenance plan in advance Cannot be set in the corresponding elevator control device. That is, unless the inspection date is approached, the inspection date information and the like cannot be set in the corresponding elevator control device. Therefore, it is often impossible to thoroughly inform the user of the inspection date and time.

  In addition, during the normal operation of the elevator, the inspection date and time information is displayed on the hall display device on each floor, so the current position of the car and the inspection date and time information must be displayed alternately, and the inspection date and time are displayed to the user. There is a problem that information cannot be transmitted accurately and the notification effect is halved.

  Furthermore, when maintenance personnel are heading to the site, maintenance start time information or maintenance end time information is transmitted from the central monitoring center to the elevator control device of the building and displayed on the landing display device on each floor. There is a large time lag between the maintenance start time and maintenance end time sent from the central supervisory center and the actual maintenance start time or maintenance end time due to delays during the course of work or delays in maintenance work. This can cause confusion to the user.

  The present invention has been made in view of the above circumstances, and information related to maintenance is set in the elevator control device at an appropriate time, and is selectively displayed in a place that is easily recognized by the user, so that the maintenance guide information can be notified.

  The maintenance information processing unit 33 is constituted by a CPU, and functionally, as shown in FIG. 4, the maintenance information transmitted from the personal computer 4 which is an external device installed in each office of the central monitoring center or the maintenance management company. A communication control unit 33a that receives information about the maintenance information, a storage information determination storage unit 32b, a display date and time determination unit 33c that determines the display date and time of the maintenance guide information, and a maintenance information guide display unit 26 of the car operation panel 21 that stores information related to maintenance. The car display means 33d, the hall display means 33e, and the maintenance time update means 33f are provided.

  When the maintenance information determination storage unit 32b receives information related to maintenance including maintenance identification information such as a building ID and a machine ID, the maintenance information determination storage unit 32b sets the determination building ID and the determination machine ID registered in the maintenance information storage table 31a of the storage device 31. Reference is made to determine that the information is related to maintenance based on a legitimate procedure, and information related to maintenance is stored in association with the corresponding determination building ID or determination machine ID in the maintenance information storage table 31a.

  The display date and time determination means 33c determines whether or not the maintenance information display period stored in the maintenance information storage table 31a based on the built-in clock information has reached the display date and time. When the maintenance information display period reaches the display start date and time, the in-car display means 33d reads any one of the maintenance guide information of the inspection date, the inspection date and time, or the inspection period, and the maintenance information of the car operation panel 21 through the tail code 16. The information is displayed on the guidance display unit 26.

  When the inspection switch in the switch box 27 is turned on, the hall display means 33e reads the maintenance end time information stored in the maintenance end time storage area in the maintenance information storage table 31a as information related to the maintenance in advance. Or it has the function to display on the hall display device 19 installed in the hall 17 of each floor. The maintenance time updating means 33f, when a state exceeding the maintenance end time occurs due to a delay in maintenance work, the maintenance end time extended by a predetermined time (for example, 30 minutes) corresponding to the maintenance end of the maintenance information storage table 31a. By rewriting and updating the time storage area, the updated maintenance end time is displayed on the hall display device 19.

  Furthermore, the personal computer 4 is installed in each office of the monitoring center or the elevator maintenance company, and is connected to the elevator control device 3 through a public communication line network such as a subscriber telephone network, ISDN, or packet switching network. The personal computer 4 transmits information related to maintenance to the elevator control device 3 based on the building ID and the machine ID that specify the maintenance target, and registers the information in the maintenance information storage table 31 a of the storage device 31.

  Next, with respect to the operation of the elevator maintenance information guide apparatus as described above, an example in which one elevator is installed in a building will be described with reference to FIG.

  Maintenance such as maintenance information display period, maintenance guidance information, maintenance end time, etc., together with the building ID that identifies the maintenance target from the personal computer 4 based on the operation of the person in charge of the maintenance management department at a predetermined office of the central monitoring center or elevator maintenance company The information regarding is transmitted to the elevator control apparatus 3 via a public communication line network.

  In the elevator control device 3, the operation control unit 32 always controls the hoisting machine 12 based on the hall call and the car call, and controls the operation of the car 14.

  In the state as described above, the maintenance information processing unit 33 of the elevator control device 3 executes a series of processes shown in FIG. 5 when the communication control unit 33a receives information related to maintenance accompanying the building ID from the personal computer 4.

  The maintenance information determination storage unit 32b of the maintenance information processing unit 33 always determines whether there is input of information related to maintenance (S1). When the communication control unit 33a receives information related to maintenance with a building ID, there is input of maintenance information. The building ID that is the maintenance identification information sent from the personal computer 4 is compared with the building ID for determination that is the identification information for determination stored in the building ID storage area of the maintenance information storage table 31a. If the same determination building ID is registered in the storage area, it is determined as information relating to genuine maintenance, and the maintenance information display period, maintenance guide information, and maintenance end time are sequentially stored in each storage area of the maintenance information storage table 31a. After that (S3), the display date determination means 33c is executed.

  The display date and time determination means 33c determines whether or not the display start time for displaying the maintenance guide information has been reached from the maintenance information display period stored in the maintenance information storage table 31a based on the built-in clock information (S4). ), If not reached, return to step S1 and repeat the same process. When it is determined that the maintenance guide information display start time has been reached from the maintenance information display period, the in-car display means 33d is executed.

  The in-car display means 33d reads maintenance guide information from the maintenance guide information storage area of the maintenance information storage table 31a, for example, inspection date: XX month XX day, inspection date: XX month XX day XX hour, inspection period: The maintenance guide information “XX month XX day to XX month XX day” is read and displayed on the maintenance information guide display unit 26 of the car operation panel 21 through the tail code 16 (S5).

  As a result, the elevator user can receive the maintenance guidance information “inspection date: xx month xx day” displayed on the maintenance information guidance display unit 26 while riding in the car 14 and during the maintenance information display period. As a result, the elevator user can surely know the maintenance guide information.

  Then, the car display means 33d continuously displays the above-described maintenance guide information on the maintenance information guide display unit 26 from the maintenance information display period to the maintenance information display end time (S6). Here, when the display end time of the maintenance guide information is reached, the display of the maintenance guide information is ended and the hall display means 33e is executed.

  This hall display means 33e judges whether or not the flag “1” is set in the maintenance work flag storage area of the maintenance information storage table 31a (S7). The flag “1” is set under the following conditions. When the maintenance staff arrives at the maintenance site and sets the inspection box in the switch box 27 attached to the car operation panel 21 of the car 14 to ON, the operation control unit 32 or the maintenance information processing unit is connected via the tail cord 16. 33 determines that the inspection is started, and sets a flag “1” in the maintenance work flag storage area of the maintenance information storage table 31a.

  Accordingly, the hall display means 33e determines that the maintenance work starts when it determines that the flag “1” is set in the maintenance work flag storage area, and the maintenance end time (current time + maintenance work time) of the maintenance information storage table 31a. ) And is displayed on the hall display device 19 of the hall 17 on the reference floor or each floor (S8). Thereby, the elevator user can easily know when the maintenance work is completed from the display content of the hall display device 19.

  Then, after displaying the maintenance end time on the hall display device 19, it is determined whether or not the maintenance end time has passed (S9), and if not yet passed, the maintenance work flag storage area of the maintenance information storage table 31a. It is determined whether or not the flag “0” is set (S10). If the flag “0” is not set, the process returns to step S8 and the display of the maintenance end time is continued.

  In step S9, when the maintenance end time has elapsed, it is determined whether or not the flag “0” is set in the maintenance work flag storage area of the maintenance information storage table 31a (S11), and the flag “0” is not set. Executes the maintenance time update means 33f.

  When it is determined that the flag “0” is not set, the maintenance time update unit 33f adds a predetermined time, for example, 30 minutes to the maintenance end time, and rewrites and updates the maintenance end time in the maintenance information storage table 31a ( S12) Subsequently, the maintenance end time is displayed on the hall display device 19 (S8).

  In step S11, if the flag “0” is set in the maintenance work flag storage area of the maintenance information storage table 31a, that is, if the inspection switch in the switch box 27 is off, it is determined whether or not the processing is continued. Determination is made (S13), and if the process is to be continued, the process proceeds to step S1, and the series of processes described above are repeatedly executed.

  Therefore, according to the embodiment as described above, if the maintenance guide information including the maintenance information display period is transmitted from the personal computer 4 in advance to the elevator control device 3 and is registered in the maintenance information storage table 31a of the storage device 31, The maintenance information processing unit 33 automatically reads the maintenance guide information when the display start time comes, and continuously displays the maintenance information on the maintenance information guide display unit 26 provided on the car operation panel 21 in the car 14 during the maintenance information display period. Since the information is displayed, maintenance guide information such as an inspection date, inspection date and time, and inspection period can be set at an early stage according to the maintenance plan, and the user can be informed of the inspection date, inspection date and time, inspection period, and the like in advance.

  In addition, during the maintenance work of the elevator, a maintenance work flag is set and a predetermined maintenance end time is displayed on the landing display device 19 of the standard floor or each floor landing 17, so that the user can grasp how long the maintenance work will take, When the maintenance work is delayed, the maintenance time is automatically updated to a maintenance time extended by a predetermined time, so that the progress of the maintenance work can be accurately transmitted to the elevator user.

  Further, information related to maintenance is transmitted from the personal computer 4 to the elevator control device 3 and registered in the maintenance information storage table 31a. However, if the information regarding maintenance is changed thereafter, the maintenance including the building ID is similarly performed from the personal computer 4. If the information regarding is transmitted, the contents of the maintenance information storage table 31a can be easily changed.

(Other embodiments)
(1) When the maintenance information such as the inspection date and the inspection date is transmitted from the personal computer 4 according to the maintenance plan at all times, the maintenance information processing unit 33 maintains the maintenance guidance information such as the inspection date and the inspection date. It is good also as a structure which displays on the maintenance information guidance display part 26 in the passenger car 14 simultaneously with receiving. In such an apparatus, not only the maintenance information display period is not transmitted from the personal computer 4, but also the maintenance information display period area need not be provided in the maintenance information storage table 31a.

  According to this embodiment, when approaching the inspection date, maintenance guide information such as the inspection date and inspection date from the personal computer 4 is received and immediately displayed on the maintenance information guide display unit 26 in the car 14. Therefore, it is possible to enhance the effect of notifying the maintenance information such as the inspection date and the inspection date and time for the user, as compared with the conventional one in which the operation state of the hall display device and the maintenance information are alternately displayed.

(2) In the above embodiment, when the inspection switch in the switch box 27 provided in the car operation panel 21 of the car 14 is turned on, “1” is set in the maintenance work flag storage area of the maintenance information storage table 31a. However, for example, when the inspection switch on the elevator control device 3 side is turned on instead of the inspection switch on the car operation panel 21, "1" is set in the maintenance work flag storage area of the maintenance information storage table 31a. It may be configured to execute a series of processes shown in FIG.

  Further, the maintenance information storage table 31a corresponds to the inspection switch on the elevator control device 3 side and the inspection switch in the switch box 27 of the car 14, and the first maintenance work flag storage area for the control device and the car inspection A second maintenance work flag storage area is provided, and when any of the inspection switches is turned on, a flag “1” is set in the corresponding maintenance work flag area. Then, the in-car display means 33d can proceed with the processing after step S8 while confirming the flag “1” in both maintenance work flag areas.

(3) Further, when a plurality of elevators are installed in the same building, processing as shown in FIG. 6 is executed. In this case, as shown in FIG. 3, the maintenance information storage table 31a stores at least the determination unit ID among the determination building ID and the determination unit ID. In addition, information related to maintenance including maintenance identification information including at least the unit ID among the building ID and the unit ID is transmitted from the personal computer 4 to the elevator control device 3.

  The maintenance information processing unit 33 of the elevator control device 3 executes the processing of steps S1 to S4 shown in FIG. 5, and starts displaying maintenance guidance information from the maintenance information display period stored in the maintenance information storage table 31a in step S4. When it is determined that the time has been reached, the car display means 33d is executed.

When it is determined that the display start time has been reached, the in-car display means 33d identifies which of the cars has reached the display start time from the determination car ID in the maintenance information storage table 31a. Then, the in-car display means 33d stores maintenance guidance information related to the specific car from the maintenance guidance information storage area of the maintenance information storage table 31a, for example, inspection date: XX month XX day, inspection date: XX month XX day XX. Maintenance guide information such as “hour, inspection period: XX month XX day to XX month XX day” is read out and displayed on the maintenance information guide display unit 26 of the car operation panel 21 through the tail code 16 (S21-1, S21). -2, ..., S21-i, S22). In other words, for example, an inspection date is displayed on a specific unit, for example, inspection date: XX month XX days. Thus, the elevator user can display “ It becomes possible to see the maintenance guide information indicating that the inspection is to be performed on “XX month XX day with the specific unit”, and the elevator user can surely know the maintenance guide information regarding the specific unit.

  The in-car display means 33d proceeds to step S23, determines whether the display start time of the next unit has been reached from each maintenance information display period stored in the maintenance information storage table 31a (S23), and displays the next unit. If the start time has been reached, the next unit is identified (S21-1, S21-2,..., S21-i), and the inspection is performed on the specific unit, for example, on the inspection date: xx month xx days. A message is displayed (S22).

  In step S23, if the display start time of the next unit has not been reached, the maintenance guide information is displayed on the maintenance information guide display unit 26 continuously from the maintenance information display period to the maintenance information display end time (S24). Here, when the display end time of the maintenance guide information is reached, the display of the maintenance guide information is ended and the hall display means 33e is executed.

  The hall display means 33e and the maintenance time update means 33f execute the processes of S8 to S12 shown in FIG. 5 and check the processes of S8 to S12 in each car (S25) when the inspection for each car is finished. . Then, when the inspection work of all the units instructed from the personal computer 4 is finished, it is determined whether or not the process is continued (S26), and the process returns to step S1 or the process is finished.

  According to this embodiment, in addition to the same effect as the above-described embodiment (FIGS. 1 to 5), when a plurality of elevators are installed, information regarding maintenance is specified to the user while identifying the number. You can be notified.
