Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to elevators, and more particularly to a group management control elevator apparatus that improves the signal transmission system of an elevator system.

[Technical background of the invention and its problems] In recent years, with the development of semiconductor technology, the use of semiconductor elevator ti control devices is rapidly progressing. In particular, the use of microcomputers has greatly improved the functionality of elevator control devices, and the method of transmitting signals between control panels has also changed accordingly.

For example, in the conventional system, the signal transmission method is the control panel that controls the gates of each individual elevator, and the control panel for group management control that operates these individual elevators efficiently.
A level transmission system was adopted in which each of the 11 boards had a dedicated input/output terminal for each signal, and the signals were sent and received by connecting them with transmission lines for each signal, but microcomputers were used in the elevator control system. Because of this, all signals are being transmitted in parallel or serially using a common transmission line.

Here, such a conventional method will be explained.

As shown in Fig. 4, if approximately 3 to 8 individual elevators are installed and these are operated by a group control side 4 (l), 3 to 8 individual elevators are controlled by a control unit 2 that controls the elevator cars 4 to raise and lower them respectively.
141, one group management control panel 2, which controls all of these, comprehensively grasps the overall operating situation, congestion level, floor usage level, etc., and sends control signals to achieve the optimal operating situation. is given, and elevator car 4 is operated. Various signals are exchanged between the elevator car 4 and the single control path 1 via the traveling cable 5. The various separate ps exchanged between the single valley O board 1 and the group management control board 2
Signals and operation information signals from each individual control I panel 1 are transmitted via transmission lines provided between the individual control 21111 and the group management control 2 (I panel 2).

However, in the conventional device, the operating status of each elevator car 4 that is under group management control is displayed, and the i3 on the group management side
[For the monitoring panel 6 that performs operations and settings in 1, the common panel 3
Each individual control path 1 is connected to the monitoring panel 6 via the common panel 3 to transmit and receive signals. That is, in transmitting the signal of each single tapH to the monitoring panel 6, each single control panel 1 and the common panel 3 that relays each signal are connected with separate transmission lines, and each signal is once connected to this common channel. 3, the necessary processing is performed here, and the processed signals are sent to and received by the monitoring board 6.

Therefore, in the case of this type of system, (1) a common board is required, which makes the system complicated;
The cost will be high.

(2) Since elevator position signals, direction signals, failure signals, etc. are transmitted from the single control unit 21m to the group management control panel and the common panel, the number of wiring lines and the number of transmission boats inevitably increases, making it complicated.

(3) Due to the reason (2) above, the reliability of the system decreases as the number of wires and components increases.

Is it true that display formats that are easier to read are now being adopted? From the y11 side, for example, it has become possible to set the control mode for the single control path and the group management control panel using the keyboard, and the number of information interfaces between carriers is increasing. From the point of view that the above-mentioned tendency becomes more severe, there is a strong desire for a system with a simple configuration that can cope with the above-mentioned tendency.

[Object of the Invention] The present invention has been made in view of the above-mentioned circumstances, and its object is to provide an rF! signal transmission system in an elevator system that performs group management control. The objective is to provide an inexpensive and highly reliable group management control elevator system with a simplified configuration.

[Summary of the Invention] To achieve the above object, the present invention provides a plurality of suppressors each controlling a single elevator, and a group control system controlling the overall movement of each single elevator by controlling these control devices. A supervisor who displays the operation of the control panel and the entire elevator and gives operation instructions. In an elevator system equipped with a control panel and a supervisory board for the elevator, ! Yu is connected through the group management control panel 1, and signals are exchanged between the elevator control panel and the monitoring panel through the group management control panel. By connecting each control panel of a single elevator and the monitoring panel through the cable to send and receive signals, a common panel is no longer required, which simplifies the configuration and connection of signal lines, simplifying the configuration. At the same time, we aim to improve reliability, reduce costs, and increase the degree of freedom in adding capacitors to fully meet the diversifying needs of our customers.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a block diagram showing the basic configuration of this apparatus, and FIG. 2 is a functional block diagram of its group management control panel. In the figure, 1 is a single system t that controls the operation of each elevator car 4.
ia board, 20 is a group management control board that controls these single control boards 1, and is mainly thinned out with a microcomputer. The elevator car 4 is operated by giving control signals to achieve optimal operating conditions by comprehensively grasping the degree of use of floors and floors. Reference numeral 6 denotes a monitoring panel for displaying the operating status of each elevator car 4 that is under group management control and for operating and setting the group management control. 5 is a traveling cable.

Here, in this device, the conventional common panel 3 is abolished, and the monitoring panel 6 and the single unit u (l panel 1, group management control panel 20
All signals are exchanged with the group management control panel 20. In other words, Gunkan] 3I! Control σD board 20
has a quadruple of 3 common boards.

Next, the operation of the present device consisting of the above (1) will be explained.

Signals between the single control panel 1 and the group management control panel 20 necessary for group management include the elevator position, direction (elevating/lowering), door status ( (opening/closing) and elevator corner loads, etc.
Conversely, from the group management control alt 20 to the single control panel 1, there are signals, door openings, etc. for landing calls to be answered.

Since there is no common panel in the device of this invention, 8 yen management control panel 2o
In addition to the above, there are also types of signals sent and received between the control panel 1 and the control panel 1. The signal to board 6 increases.

The signals to the monitoring panel 6 include the position of each elevator,
There are direction, fault signals, and status signals for controlled operation in the event of a fire, private photoelectric operation, earthquake, etc. What are the advantages of the present invention? ! The position, direction, and fault signals sent to the panel 6 are also necessary for group management control, and even if the signals are sent to and received from the monitoring panel 6 via the group management side 0Ωa20, the group management control will not be possible. For the board 20, these points do not particularly result in an increase in the types of signals. In addition, the status signals of control operation in the event of a fire, private power generation operation, earthquake occurrence, etc. become additional signals for the group management control panel 20, but since group control operation is not performed in the control operation state, Since the detailed control control TLL 20 is in a state with the most margin for control operations, signal processing during control operation can be done line by line easily considering the processing capacity of the microcomputer, and the burden on the group control control panel 2O is reduced. No.

In consideration of recent technological trends and customer needs, we will be able to increase the amount of processing required by giving commands to change the operating state from the keyboard of the monitoring panel 6, so that the operating state can be changed arbitrarily. There are many things you can do.

Examples include changing the operation mode of group management, schedule operation according to time of day, service operation of a single elevator on a specific floor, and inputting a password in the password code registration method for car calls.

These are group management side t2[I! Since this information is given to the group management control 20m20, the addition of such processing is necessary in this device where the monitoring panel 6 and the group management control board 20 are directly connected by a signal line. This problem can be solved by simply adding a program.

In the conventional case, in addition to adding a processing program for the group management control panel 20, processing for giving commands to change the above-mentioned operating status sent to the common panel from the keyboard of the monitoring panel 6 to the management control type 8'I: In addition to adding multiple I-layers, it is necessary to add a new signal line to connect the group management control W20 and the common board, and this cannot be done unless the common board has sufficient space for input/output ports, etc., and the hardware In addition to being subject to restrictions, what's more? ! turn into a turmoil.

FIG. 2 is a multilayer block diagram of the group management control panel 2. The group management control panel 20 exchanges a group management signal S1 and a management operation signal S2 with the single control panel 1.

Based on these signals, the group management control II edict 20 performs the group management processing block 21 and management operation! The necessary processing is performed on the IIIN blotter block. Further, the signals processed by the control operation processing block 22 are exchanged between the group management control panel 20 and the monitoring panel 6.

In this way, the single control panel 1 and the monitoring panel 6 are connected via the group management control II 20 to send and receive signals, so there is no need for a common panel. In addition, most of the signals given to the monitoring panel 6 are necessary for group management control, and the group management control panel
Since it can be used jointly with the control panel 20, the number of types of signals does not increase for the group management control panel 20.Also, the group management control panel 20 has more signal processing during control operation, but the number of signal types is increased during control operation. Since no control is performed, the group management control panel 20 is in a state with the most margin for control 1JII operation.
There is no burden on the group management side η[1120. Therefore, drying is simplified, reliability is increased accordingly, and costs can be reduced. In addition, since there is an extremely high degree of freedom in adding multiple layers, it is possible to fully meet the needs of increasingly diversified customers.

FIG. 3 is an example of the device shown in FIG. 1 with enhanced reliability in emergency operation.

Fire control operation and private power generation control operation, which rank highest among the elevator operation modes, are generally operated by the operator. This is done manually from M board 6.

In these emergency situations, if the intelligent functions of the group management control panel 20 and the monitoring panel 6 are impaired or the transmission function is impaired, the linearity of the entire elevator will be impaired, so only these signals are transmitted individually. The monitoring panel 6 and each individual control panel 1 are directly connected to each other, and the level transmission is applied, thereby minimizing the number of wires and ensuring that the number of wires is kept to a minimum. It is something.

Thereby, in addition to the advantages of the previous embodiment, reliability in an emergency can be dramatically improved.

[Effects of the Invention] As detailed above, according to the present invention, it is possible to simplify the configuration of the entire elevator system, reduce the cost by one point, and improve reliability. It is possible to provide a group management control elevator system having the following characteristics.
