The present invention relates to a group management control technology through a serial transmission line of an elevator, in particular, a plurality of aerobic control panel and the input and output terminal devices for controlling the devices installed in the platform of each floor through a serial transmission line connected In the military management system that communicates the information required for the operation between each other by serial transmission method, so that the optimal breathing machine is assigned to the call, priority is given to the exhalation control panel when an abnormality occurs in the military control panel and it fails to function. The present invention relates to a group management signal transmission control device of an elevator so that an aerobic control panel in the group can perform a group management function.

FIG. 1 is a block diagram of a signal transmission apparatus in a general management system of an elevator, and as shown in FIG. 1, the first unit control panel 12 and the second unit control panel 13 through serial transmission lines L1 and L2. A military management group 11 which periodically collects driving information of the cars 14 and 15 while performing serial communication and allocates an optimal breathing service based on the driving information when a platform call signal is generated; A unit 1 control panel 12 and a unit 2 control panel 13 for controlling the driving of the cars 14 and 15 under the control of the military management panel 11; Platform operation display devices 16 and 17 connected to the unit 1 control panel 12 and the unit 2 control panel 13 through platform signal transmission lines L3 and L4, respectively, for transmitting and receiving information necessary for operation; ; It is composed of a platform call registration device 18 which is connected to the military control panel 11 through the platform signal transmission line (L5) and provides the platform call signal to the military management panel 11, the military management of the conventional elevator configured as described above The control signal transmission operation is as follows.

When a passenger waiting for a platform attempts to register a call through the platform call registration device 18, a call signal generated therefrom is supplied to the military control panel 11 through the platform signal transmission line L5, and at this time, the group management panel. 11 again outputs a call registration acknowledgment signal through the transmission line (L5) so that the rising call lamp (△) or the lower call lamp (▽) installed in the platform call registration device 18 is turned on, so the passengers You will notice that the call is registered.

Subsequently, the military management group 11 performs an assignment operation on the basis of the collected breathing information, that is, the driving state information of the cars 14 and 15, and allocates the optimal breathing unit to the currently generated platform call. For example, when the car 14 is service-assigned, the assigned call registration information is serially transmitted to the first unit control panel 12.

Accordingly, the first unit control panel 12 receiving the assigned call registration information transmits the assigned call registration information to the boarding point driving display device 16 through the boarding point signal transmission line L3 and controls the driving of the car 14. As a result, the car 14 operates in the platform where the call is generated.

On the other hand, FIG. 2 is a block diagram of another signal transmission device in a general management system of an elevator as compared with FIG. 1, the platform call signal is not transmitted directly to the military control panel 21 through a separate burner line, the platform Call registration device 18, platform operation indicators 26, 27, platform signal transmission lines L3, L4, exhalation control panels 22, 23. It is configured to be transmitted through the serial transmission line (L1), (L2), the operation of which is described as follows.

When a passenger waiting on the platform attempts a calling operation through the platform call registration device 28, the call signal generated from the platform is displayed on the platform operation display devices 26, 27, platform signal transmission lines L3, L4, The exhalation control panel 22, 23, serial transmission line (L1), (L2) is sequentially transmitted to the military management panel (21).

At this time, the military management panel 21 performs an assignment operation to allocate the optimal call. For example, when the car 25 is assigned to the service, the assigned call registration information is transmitted through the serial transmission line L2. It transmits to the exhalation control panel 23 side. Accordingly, the control unit 23 transmits the call registration information and the car driving state information to the boarding point driving display device 27 through the boarding point signal transmission line L4, and controls the driving of the car 25 to control the driving of the car 25. (25) proceeds to the platform where the call was made.

At this time, the boarding point driving display device 27 that receives the call registration information outputs the signal to the boarding point call registration device 28, and the rising call lamp (△) or the lowering call installed in the boarding point call registration device 28. The lamp ▽ lights up so the passenger knows that his or her calling has been registered.

However, in the case of a military management signal transmission control device such as the former, when a failure occurs in the military control panel, no unit responds to the call of the platform and the passenger cannot use the elevator at all. In the signal transmission control device, if a military control panel breaks down, it cannot be allocated from the military management department, so each unit operates independently, and more than one unit responds to the platform call of a specific floor. And shortening the life of the elevator.

Accordingly, an object of the present invention is to provide a group management signal transmission control apparatus of an elevator so that the exhalation control panel in the priority of the exhalation control panel to exercise the military management control function when the abnormality occurs in the military control panel and can not function properly. Is in.

3 is an exemplary block diagram of a group management signal transmission control apparatus for an elevator of the present invention for achieving the above object, as shown therein, the first unit control panel 32, the second unit through the serial transmission line (SL1) While performing serial communication with the control panel 33, the driving state information of the cars 34 and 35 is periodically collected, and the platform call signal is received through the serial transmission line SL2, and based on the driving information, A military management group 31 for allocating the service to the unit; The service is normally assigned by the military management team 31 to operate the cars 34 and 35 to the corresponding floors and check whether the military management panel 31 is faulty or not according to the preset priority when the failure is detected. An exhalation control panel 32, 33 for selecting a master exhalation control panel of the control unit and performing a group management control function on the remaining slave exhalation control panels including itself; Platform driving display devices 36 and 37 which receive the driving status information from the exhalation control panels 32 and 33 through the platform signal transmission lines SL3 and SL4 and display the driving floor and direction. ; The platform call signal generated from the platform call registration device 38 is transmitted to the military control panel 31 and each unit control panel through the serial transmission line SL2, and the calling registration information supplied through the opposite path is called the platform call. An input / output terminal device 1 (39) for transmitting to the registration device (38); It consists of a platform call registration device 38 for generating a platform call signal by the selection of passengers waiting at the platform, and receiving the platform call registration signal from the input / output terminal 1 (39) to display the driving direction. When described in detail with reference to Figures 4 to 10 attached to the operation and effects of the present invention configured as follows.

First, the basic internal operation of the military management panel 31, the exhalation control panel 32, 33, the input / output terminal device 1 39 will be described with reference to FIGS.

The military management unit 31 is composed of a plurality of microcomputer control circuits, i.e., a dual system consisting of a driving system 51 and a standby system 52, as shown in FIG. 5, so that the standby system 52 is normally in a standby state. The system 51 controls the assignment operation and the group operation command for each of the breath control panels 323 and 33.

However, when the driving system 51 becomes inoperable due to a failure or the like, the central processing unit 52A, like the driving system 51, can cause the standby system 52 to dash the function of the driving system 51. ), Memory 52B consisting of ROM and RAM, parallel communication interface 2 (52C) for communication with parallel communication interface 1 (51C) of operating system 51, serial communication interface 3 (52D) for serial communication, and serial It consists of communication interface 4 (52E), and is connected to serial transmission lines SL1 and SL2 in the same manner as the operating system 51.

A plurality of exhalation control panels having the same configuration are connected to the serial transmission lines SL1 and SL2, and FIG. 3 shows two exhalation control panels 32 and 33, and FIG. The internal configuration of (32) is shown as an example. That is, the first control panel 1 (32) includes a central processing unit (61), a memory (62) consisting of ROM and RAM, a parallel communication interface 3 (63), a serial communication interface 5 (64), and a serial communication interface 6 (65). The parallel communication interface 3 (63) is connected to the platform input / output line and the machine room input / output line through the platform signal transmission line (SL3), and the serial communication interface 5 (64) and the serial communication interface 6 (65) are serial transmission. It is connected to the lines SL1 and SL2, respectively.

As shown in FIG. 7, the input / output terminal apparatuses 1 and 39 are connected to the central processing unit 71, the memory 72 composed of ROM and RAM, the parallel communication interface 4 73, and the serial communication interface 7 74. The serial communication interface 7 74 is connected to the serial transmission line SL2 and the parallel communication interface 4 73 is connected to the boarding point call registration device 38.

When the driving system 51 of the military management panel 31 operates normally, the military management panel 31 receives the driving status information from each of the air control panels 32 and 33 through the serial transmission line SL1, Another serial transmission line SL2 receives a call signal from each platform input / output terminal device, for example, input / output terminal device 1 (39), and selects an optimal call to select an optimal call that can respond to the call. After the execution, the call information and the call registration information allocated are transmitted to each of the control unit 32, 33 and the input / output terminal 1 (39).

Accordingly, each breath control panel 32, 33 edits the call registration information to be operated based on the assigned call and key call information of the self-expiration machine, and accordingly the car 34, 35 In this case, the driving state information is transmitted to the military control panel 31 through the serial transmission line SL1, and the boarding point operation display device 36 through the platform signal transmission lines SL3 and SL4. ), (37). In addition, the input / output terminal device 1 (39) transmits the call registration information received from the military management panel (31) to the boarding point call registration device (38).

If the operation system 51 of the military management panel 31 is broken, the same control as described above is performed in the standby system 52. However, if the standby system 52 also fails, the military management control function by the military control panel 31 cannot be expected at all. At this time, the exhalation control panel having a higher priority among the plurality of breath control panels is the military control panel 31. ) Will perform the military management control function. As described above, when the operation system 51 and the standby system 52 of the military management panel 31 are both broken or the military management panel 31 is not separately adopted at the design stage, the circuit configuration is substantially as shown in FIG. 4.

For example, if the exhalation control panel belongs to the military control panel 31 and the exhalation control panel has four units including the exhalation control panels 32 and 33, the exhalation control panel with a low exhalation number has a priority order. Unit 1 control panel 32 is a master unit control panel, the remaining unit 2-4 control panel is a slave unit control panel, in this state described the group management control and operation control signal transmission process as follows.

The first unit control panel 32 selected as the master unit receives the platform call information through the serial transmission line SL2 and selects the optimum unit to respond to the call to the remaining units including itself. Perform an assignment operation, and transmit the allocated call registration information to the second to fourth control panels through the serial transmission line SL1 and to the input / output terminal device 1 39 through the serial transmission line SL2.

At this time, the operation of the 3rd and 4th control panel including the 1st control panel 32, the 2nd control panel 33 is as described above. In addition, the operation signal flow of the first unit control panel and the remaining slave unit control panel selected as the master unit is shown in FIG. 10, and the unit 1 control panel 32 also fails in the same way when the failure occurs in the unit No. 2 control panel in the same way 33 is selected as the master exhaler, and the remaining 3rd and 4th control panels are selected as slave exhalation control panels and operate as described above.

Here, the signal transmission process of the exhalation control panel during parallel operation will be described with reference to FIG.

In the first step SC1, the master unit is determined and the master unit is operating normally. If the condition is established, the process proceeds to the third step SC3. If the condition is not established, the process proceeds to the second step SC2. From the exhalation control panel to which it belongs, the exhalation control panel which has priority and can operate normally is selected as a master exhalation unit.

Subsequently, in the third step SC3, each exhalation control panel checks whether it is selected as the master exhaler, and if it is selected as the master exhaler, performs the exhalation assignment operation for the platform call call in the fourth step SC4, Proceed to step 5 (SC5) and transmit the allocated call call to each unit control panel. However, if the condition is not established in the third step SC3, that is, if it is determined that the user is not selected as the master unit, the process proceeds to the sixth step SC6 and receives the platform call allocation call information from the master unit control panel. .

Subsequently, in the seventh step SC7, the call registration information is edited by the platform call allocation call and the car call call, and the procedure proceeds to the eighth step SC8 to transmit the registered call information to the master call control panel. Subsequently, in the ninth step SC9, each breath control panel controls the driving of the car according to the registered call registration information. In addition, in step 10 SC10, information to be output to each input / output terminal device is edited, and in step 11 SC11, the edited output information is transmitted to each terminal device.

That is, when the military management panel 111 operates normally, the military management panel 111 performs assignment operation on the platform call, and assigns the assigned call information and call registration information to each of the control unit 112, 113 and the input / output terminal device. 2 to 119, and when a failure occurs in the military control panel 111 and the military control function cannot be exerted, the exhalation control panel having a higher priority among the plurality of air control panels is the military management control of the military control panel 111. Will perform the function instead.

As described above, when both the operation and standby systems of the military management panel 111 fail or the military management panel 111 is not separately adopted at the design stage, the actual circuit configuration is as shown in FIG. 12.

However, the difference with respect to FIG. 3 is that the car position signal and the driving direction signal are transmitted to the platform driving display devices 116 and 117 via the serial transmission line SL2 and via the input / output terminal device 2 119. The operation of the input / output terminal 2 119 is described in more detail with reference to FIG. 13 as follows.

As shown in FIG. 13, the input / output terminal device 2 119 of FIG. 11 includes a memory 132, a serial communication interface 133, a parallel communication interface 134, and 135 consisting of a central processing unit 131, a ROM, and a RAM. (136), the serial communication interface 133 transmits and receives information with each unit control panel and military management panel 111 through the serial transmission line (SL2), the parallel communication interface 134 is a platform call registration device A call signal is supplied from 118 to output a lamp lighting signal, and the parallel communication interface 5 (135) outputs driving status information to the platform driving display device 116 of Unit 1, and the parallel communication interface 6 (136). The station 2 outputs the driving state information to the platform operating display device 117.

As described in detail above, the present invention can normally perform the assignment operation so that the military control panel receives the platform call signal to select the optimal breathing machine for each unit, the failure occurs in the military control panel can exhibit its function. If not, one unit control unit is selected from each unit control panel belonging to the military control panel according to the prescribed rules, and the other unit is selected as the slave unit control panel to replace the group management control function. Even if a failure requirement occurs, no unit responds to one platform call or two or more units do not respond at the same time, thus ensuring stable and efficient operation.
