Furthermore, as another prior art, Japanese Patent Application Laid-Open No. 54-108335
The technique described in the above publication is known.

This conventional technology has a structure in which a hall call is given to the group management control device via the group management control device, and the transmission abnormality with the group management control device is checked on the side of the car control device side. , the machine control device that has hall call input performs service on its own machine, and the machine control device that does not have hall call intake performs backup operation by operating each floor of its own machine to prevent a complete system failure. , which performs continuous transportation services.

[Problem to be solved by the invention] Recent elevator systems aim to reduce the number of wires between equipment installed in the hall and control devices, thereby shortening the wiring work period at construction sites where there is an increasing shortage of manpower. For this purpose, a hall input/output terminal device is provided, and the device and a control panel installed in the machine room are often connected by a common bus.

The conventional technology that uses the common bus described above is
When configured by connecting to the car control device, it takes a certain amount of time from reception of the hall call to transmission to the group management control device, resulting in a problem that immediate guidance is delayed. Furthermore, in the prior art, when an attempt is made to take in a hall call directly by the group management control device, the group management control device

An object of the present invention is to provide a group management elevator control system capable of alleviating the degree of system failure and continuously providing normal transportation services.

[Means for Solving the Problems] According to the present invention, the object is that when the group management control device is abnormal, each car control device performs hall call registration and elevator operation services; By making the group management control device interface with the common hall call button, in normal times, each machine control device controls transmission with the hall input/output device, and the group management control device controls this transmission. Simultaneously receives the signals, directly captures the hall call button signal, sends the response light control signal based on the hall call registration signal to the machine control device, combines it with other output signals, and outputs it to the hall input/output terminal device. This is achieved by controlling the lighting of response lights, etc.

[Operation] During normal times, the group management control device can take in data from the input/output devices that are transmitted between the unit control device and the input/output devices in parallel, so the group management control device and the input/output device can There is no need to provide a separate transmission path between the output device and the output device. Also,
By monitoring this transmission, the group management control device and unit control device can easily discover transmission failures, and depending on the condition of the failure, the unit control device can directly detect transmission failures without receiving instructions from the group management control device. Elevator operation can be controlled, and even if hall calls cannot be transmitted, elevator operation services can be performed using hall calls generated within the group control device or unit control device. be able to.

When a door is opened on the floor, an operation permission command is output to perform control to notify a display installed in the car or the like by the alarm control process in step C560.

Further, for example, if there is an abnormality in the input/output terminal device 4a of the BIF on the first basement floor, the unit microcomputer lal disconnects this slave station terminal and starts service, and also communicates with the maintenance center (not shown) through the network transmission line Ll 7a. 1
! A maintenance terminal connected via a communication line reports the occurrence of an abnormality, the floor of the abnormal slave station, and the part number stored and managed.
In order to directly output the information, trouble display on the monitor inside the control panel and network transmission data input/output processing shown in step C800 are performed, and then direct output processing is executed in step C180. As a result, the aforementioned data is sent to the center via a maintenance terminal (not shown), a telephone line, etc., and the center can take appropriate and prompt action.

FIG. 8 is a block diagram showing the configuration of another embodiment of the present invention. Another embodiment of the present invention is a two-parallel elevator management system (hereinafter abbreviated as Duplex).
This is an example of the case where this is applied to, and this will be explained below.

In Figure 8, the elevator control microcomputer Ia installed in the control panels of No. 1 and No. 2
I and Ia2 are equipped with a machine control function and a function of controlling two elevators in association with each other, such as hall call assignment control, distributed timing control, management operation control, and pattern operation control for Duplex elevators. The control function for each machine is completely the same in terms of hardware and software as in the embodiment described above, and the management control function is distributed to each machine control device.

In a Duplex elevator configured as shown in Fig. 8, communication boats (transmission control equipment) 200al, 20Oa2.
1 and 200b2 are configured with a plurality of transmitting and receiving circuits for each device, and are connected to machine microcomputers lal and 1a2, respectively. , the I10 transmission control device 200al of No. 001 has a path line 3cl connecting it to a terminal (not shown) installed in the car,
A path line 3a4.3el connecting the terminals 5al and 5bl installed in the hall and the transmission control device 200b2 of the N002 machine control panel 10a2 is connected.

Furthermore, this transmission control device 200al includes an I10 pass line 3b4 for middle odd-numbered floors, which is used when the number of floors increases, and a ■10 pass line 3dl for high-rise odd-numbered floors.
can be connected.

Furthermore, an expansion communication board 2b is installed on the machine microcomputer lal, and the transmission control device 2o○a3.200a
In this case, the transmission control device 200a3 has an I10 pass line 3 for middle even-numbered floors.
c2a and transmission control device 200a3 can be connected to I10 pass line 2d2a for odd-numbered floors.

In addition, the transmission control device 200a2 includes a pass line L17 that connects the transmission control device 200b2 of the machine control panel 10a2 of machine No. 002, and a pass line that connects the terminal 5a2.5b2 installed in the hall of machine No. 2. 3a5 is connected. No. 2 transmission control device 200
bl, 200b2 is also connected to the pass line in the same way as No. 1 machine.

The management and control device for the Duplex elevator configured as described above includes No. 1, No. 62, and No. 62.
Although the control devices of the No. 1 car have the same management control function, in the following explanation, it is assumed that the control device of the No. 001 car shares the management control function.

In such a configuration, the transmission control device 20 of the N091 machine is connected to the path line L17 that performs communication between each machine.
0a2 becomes the control station, and when communicating with terminals installed in the car and each hall, No. 1 transmission f
The M# device 200al and the No. 2 transmission control device 200bl serve as control stations.

These transmission control devices serving as control stations transmit and receive data to and from each terminal using a polling selection method through each path line. Transmission and reception of this data will be explained below.

First, the transmission control device 200a2 of No. 1 car, which is the #control station for inter-car communication, sends out a synchronization signal to start communication from its boat Pa6. At the same time, transmission control device 2
00al executes a hauling thefting sequence between the boat Pa1 and a car terminal (not shown) through the pass line 3cl. At this time, the transmission control device 200a1 cuts the boat Pa3 so as not to send a signal to the pass line 3a4.

At the same time, the No. 2 car microcomputer 1a2, which has received the synchronization signal to start communication with the car terminal, also executes the hauling averting sequence with the car terminal (not shown), as in the case of the No. 1 car. Similarly, in this case, the boat Pb3 is controlled to be in the cut state so that no signal is sent to the pass line 3a5.

During this period, boat Pa6 of No. 1 transmission control device 200a2 sends a synchronization signal to start communication, and then No.
The transmission control device 200b2 of the No. 2 car sends commands related to running control of the No. 2 car, and upon receiving the commands, sends signals such as the elevator driving direction and position from the boat Pb6, and terminates communication with the car. The signal is returned to the boat Pa6 of the transmission control device 200a2 of No. 091.

And, No. 1 with elevator operation management control function.
, the machine microcomputer LAL that controls the elevator of machine 1
When detecting that the boat Pa 1 of the transmission control device 200al and the boat Pa6 of the transmission control device 200a 2 have respectively finished the above-mentioned predetermined communication, it starts execution of the next sequence.

Then, in the next period, as described above, when the boat Pa6 of the transmission control device 200a2 of No. 1 machine sends out a synchronization signal to start communication with each terminal installed in the hall, each car Transmission control device 200a 1 and 2
Each station 00a2 functions as a control station and executes a hole selection sequence in order to transmit and receive data to and from each hole terminal.

At this time, the boat Pa5 of the transmission control device 200a2 of the No. 1 machine receives a push button input sent from the hall terminal (5a2.5b2, etc.) of the No. 2 machine to the boat Pb3 of the transmission control device 200bl via the pass line 3a5. The signal is being received by eavesdropping. In this way, the pass line 3a5 connected to the hall terminal of No. 2 is connected to No.
By configuring it to be connected to the transmission control device of No. 1, the No. 1 machine microcomputer LAL for controlling No. 1 Duplex elevator, which has the management control function of the Duplex elevator, is connected to No. 2.
You can instantly obtain the hall button input information for the machine number.

Pass line 3a5 is No. 1 transmission control device 20
If it is not connected to 0a2, the hall push button information is first inputted to the No. 2 transmission control device 200b1,
Next, this information is read by the machine microcomputer 1a2 for operation control, and further sent to the transmission control device 200b2.
This signal is sent to No. 2, and finally the No. 001 machine microcomputer lal for operation control receives this information.

In the above-mentioned embodiment, a terminal device such as a hall input/output terminal is provided for each machine, and a plurality of these terminal devices are connected to a machine control device through a small number of common transmission paths. Power is supplied to the input/output terminal devices connected to the transmission lines from a common power source. As a result, even if one of the elevators is in trouble, the other elevator can operate and service both elevators normally.

According to the above-mentioned embodiment in which the present invention is applied to a Duplex elevator, for example, even if the power of No. 092 is cut off or the control device is out of order,
Since the hall terminal of No. 002 machine is connected to the transmission control device of No. 1 machine through pass line 3e2,
Even if a passenger operates the push button of No. 002, the signal is taken into the No. 1 microcomputer for controlling No. 001, and the user can receive the service.

Therefore, according to other embodiments of the present invention described above, No.
Even in the event of power cutoff or failure of the control device of No. 2, elevator operation service can be performed without deteriorating elevator service performance. Also, No,
Similarly, the power cutoff or failure of the control device of the No. 1 machine can be handled by the control device of the No. 2 machine.

[Effects of the Invention] As explained above, according to the present invention, the number of transmission paths between the group management control device and the unit control device can be reduced;
Moreover, even when the group management control device is abnormal, the degree of system failure can be alleviated and normal elevator operation services can be continuously provided.
