  However, the transmission control apparatus of the elevator system shown in FIG. 9 still has the following problems to be solved.

  That is, each hall call registration device 13 provided in the elevator hall on each floor is a user in the elevator hall only during the period when the control device 11 of this elevator system is operating the elevator in the “normal operation mode”. And the current position of the car 7 may be displayed on the display unit 15. Therefore, as the serial transmission line including the signal line 26, it is not necessary to use a serial transmission line backed up in particular.

  However, the maintenance device 18 is also used for rescue operation of an elevator using a backup power source such as a battery when a user is trapped in the car 7, for example, when a power failure occurs. Therefore, as a serial transmission line including the signal line 25, it is necessary to use a serial transmission line backed up.

  As a result, the hall call registration device 13 and the maintenance device 18 on the top floor arranged close to each other cannot be incorporated into one serial transmission line. For this reason, the transmission control apparatus cannot be further simplified.

  The present invention has been made in view of such circumstances, and by incorporating a hall call registration device and a maintenance device on specific floors arranged close to each other into one serial transmission line backed up by a power backup circuit. , After sufficiently securing the functions required by the maintenance device, it is possible to integrate the serial transmission line with the adjacent hall call registration device, further simplify the transmission control device, and It is an object of the present invention to provide a transmission control device for an elevator system capable of individually controlling a hall call registration device and a hall call registration device on another floor.

In order to solve the above problems, the present invention installs a hall call registration device in an elevator hall on a plurality of floors of a building, and moves up and down in a hoistway formed in the building, and from each hall call registration device.

  In the transmission control device of the elevator system configured as described above, the second serial transmission line connecting the control device, the hall call registration device on the specific floor and the maintenance device is powered by a power backup circuit. Since it is backed up, the function of the maintenance device is not impaired. Therefore, the transmission control apparatus can be further simplified.

  Furthermore, since the hall call registration device on the specific floor and the hall call registration device on the other floor are connected to the control device via different serial transmission lines, the control device can control both individually.

  Another invention is the transmission control device for an elevator system according to the above-described invention, wherein the hall call registration device on the specific floor displays the information from the control device received via the second serial transmission line on its own display. A display sharing means for outputting and displaying the display information output from the maintenance device to the self display is provided.

  In such a configuration, the hall call registration device on the specific floor displays the current position (floor) of the car when the control device is “in normal operation” of the elevator, and from the maintenance device during “maintenance” of the elevator. Display the display information. Therefore, since the maintenance device does not need to be provided with a display, the manufacturing cost of the transmission control device can be reduced.

And a transmission cycle adjusting means for matching the transmission cycle of the first serial transmission line detected in (1). In such a configuration, since the transmission cycles of the first and second serial transmission lines are equal, the current position display timing of the car of the hall call registration device on the specific floor is the display timing of the hall call registration device on the other floor. There is no deviation.

  Another invention is the transmission control device for an elevator system according to the invention described above, wherein the transmission cycle after the adjustment of the second serial transmission line is the same as the registration device period of each hall call registration device other than the specific floor. It consists of a registration device period for the hall call registration device on the floor and a maintenance period that is at least three times as long as this registration device period. The maintenance device responds to the maintenance operation and returns the operation data of this maintenance operation. A duplicate transmission means for repeatedly setting a plurality of times during the maintenance period is provided. In such a configuration, the operation data input by the operator to the maintenance device is repeatedly transmitted three or more times, so that the reliability of maintenance of the transmission control device can be improved.

According to another aspect of the invention, in the transmission control device for an elevator system according to the invention described above, the maintenance device divides the control program according to a control program transfer instruction operation to the control device, and performs maintenance every time the transmission cycle elapses. There is a control program transfer means for sequentially setting the full service period.

  In another aspect of the invention, the control device includes a maintenance status display means for setting a display command during program transfer during each registration device period in the first serial transmission line during a control program reception period. ing.

  In such a configuration, when the control program is transferred from the maintenance device to the control device, the control program is divided and transmitted. During the transmission period of this control program, a message indicating that the program is being transferred is displayed on the display section of each hall call registration device on each floor other than the specific floor.

  In the present invention, after sufficiently securing the functions required by the maintenance device, the maintenance device can integrate the adjacent hall call registration device and the serial transmission line, thereby further simplifying the transmission control device. In addition, the adjacent hall call registration device and the hall call registration device on the other floor can be individually controlled, and the service for elevator users can be improved.

The same parts as those in the transmission control apparatus of the conventional elevator system of FIG. 9 are denoted by the same reference numerals, and detailed description of the overlapping parts is omitted. Further, the overall view of the elevator system is substantially the same as the overall view shown in FIG.

  In the transmission control device of the elevator system according to the embodiment of the present invention, each hall call registration device 13 provided in the elevator hall on each floor other than the top floor, which is a specific floor, controls the operation of the elevator via the signal line 31. The control device 30 and each hall call registration device 13 are connected to the device 30. The hall is registered by a first serial transmission line 35a composed of the first serial transmission line control unit 35 and the signal line 31 shown in FIG. Information on the current position (floor) of the call basket 7 is transmitted and received.

The control device 30 and the car call registration device 20 are the fourth serial transmission line control unit 38 and the tail code 24 shown in FIG. The fourth serial transmission line 38a configured as described above transmits and receives information on the destination floor of the car 7 and the current position (floor) of the car 7.

  As shown in FIG. 2 (a), the hall call registration device 13a provided in the elevator hall on the uppermost floor as a specific floor is provided so as to be rotatable with respect to the wall. By rotating the registration device 13a, a maintenance device 33 in which the operation unit 16 is exposed is embedded. The maintenance device 33 is not provided with the display unit 17 shown in FIG. In the maintenance execution process, the operation instruction and the response information from the control device 30 via the second serial transmission line 37a are displayed on the display 15a of the adjacent hall call registration device 13a.

  Therefore, the indicator 15a of the hall call registration device 13a displays the current position (floor) of the car 7 that the own hall call registration device 13a should originally display during normal operation and information necessary for maintenance during maintenance. A common display 15a for displaying is configured.

  The maintenance device 33 also receives a control program read from the duplicate transmission unit 52 and a PC (personal computer) 54 temporarily connected to the maintenance device 33 via a signal cable via the second serial transmission line 37a. Is provided with a program transfer unit 53 for transferring to the control device 30.

It is also possible to display on 15a.

Further, when the control program is automatically transferred from the maintenance device 33 to the control device 30 during maintenance of the elevator, the maintenance program 33 is divided into maintenance programs every time the transmission cycle T ₁ elapses. The control program 37g divided into the period 37d is set next.

  The control device 30 sets a display command during program transfer in each registration device period 35c of the transmission frame 35b of the first serial transmission line 35a during the reception period of the control program. Further, even during the maintenance period, a display command during maintenance is set in each registration apparatus period 35c of the transmission frame 35b of the first serial transmission line 35a.

  During such a maintenance period, a message indicating that the program is being transferred or maintained is displayed on the display 15 of each hall call registration device 13 other than the specific floor, so that the service for the user can be improved.
