Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an elevator control device, and in particular, to a service-through elevator system in which a plurality of elevators are installed on a plurality of floors. Control suitable for application when an elevator group control system that transmits various signals to and from a group control (common) control device for centrally controlling elevators is configured with a digital system using a microcomputer, etc. The present invention relates to a control device for a group control elevator having an information display configuration.

[Technical background of the invention]

In general, in an elevator system, in addition to a position display device that displays the movement of the elevator at each floor landing, etc., it is also possible to know the movement of the elevator corner and the status of control information while staying in the machine room during elevator maintenance inspection. A control information display device is required.

On the other hand, in conventional contact elevator control devices that use relays, etc., it is possible to judge the status of control information, etc. by directly observing the operation of the relays on the control panel. .

However, in digital elevator control systems using LSIs (Large Scale Integrated Circuits) and ICs (Integrated Circuits), there are no moving parts such as relays, so it is difficult to visually judge the movement of the elevator. There is a problem that this is possible, and some kind of solution to this problem is required.

[Purpose of the invention]

An object of the present invention is to centrally display various control information related to elevator operation with a simple configuration in order to facilitate elevator adjustment and inspection in a service-through elevator system for multiple floors. An object of the present invention is to provide a control device for a group management elevator that makes it possible to do this.

[Summary of the invention]

The present invention is a group management elevator system that controls a plurality of elevators, and is configured to display various information of each elevator machine based on information transmitted to a common group management control device via its output port. Particularly, the present invention is characterized in that it is possible to centrally grasp information on a plurality of elevators without providing an output terminal for each individual control device, and to facilitate adjustment and inspection.

In particular, in this case, it is preferable to have a configuration in which the display mode is periodically changed and outputted in a time-sharing manner to the group management control program from the same output port of the group management control device, and the display device is turned on and off using hardware. Yes, reduction in the number of connection lines between the display device and group management control device, compatibility for each system,
The advantages obtained may have little effect on the entire group control elevator system.

[Embodiments of the invention]

FIG. 1 is an external view of an elevator control information display device in one embodiment of the present invention. In this embodiment, the car position, direction, load, door, car call, and hall call can be centrally displayed in a system with four group control elevators and up to 16 floors. AA~ in Figure 1
AD means machines A to D, respectively.

FIG. 2 is a diagram showing the system configuration of the group management elevator control system of this embodiment. The control information display device 1 is
It is connected to the output port of the group management control device 2 common to a plurality of elevators in the group, and by signal transmission between each individual control device 3A to 3D corresponding to each elevator and the group management control device 2. The various control information obtained for each of the A to D machines is displayed using the output from the entire group management control device 2.

FIG. 3 is a diagram showing the format of the output port of the group management control device 2 described above. This output port is OUT 1
It is an output port with a 2-byte configuration of 2 and 2, and OUT
Display mode (bit <
3>, <2>) and the specified machine code (bit < 1
>, <O>) Specify all and output all data to be displayed corresponding to the above display mode and machine code to OUT 2.

FIG. 4 shows an example of a specific format of data to be displayed. Each piece of information is output in bits for each of the 45 types of display modes. Therefore, the group management control device 2 outputs information corresponding to each machine code and display mode in the format shown in Fig. 4 at regular intervals while changing the machine code and display mode on an average basis in a time-sharing manner. The output signal is synthesized as shown in FIG. 2 and output via both OUT1 and OUT2.

FIGS. 5(,) and 5(b) show the configuration of an example of a specific circuit of the control information display device 1. FIG.

In FIG. 5(a), the output of the group management control device 2)
The machine code and display mode signal output from OUT 1 are sent to decoding circuits DCI and DC2, respectively.
Each signal is decomposed into four types of signals. For example, the logic of the machine code signal is from II O# to 1"
The one-shot circuit O8 that outputs the z4 pulse generates one-shot pulses at a constant interval on the signal line corresponding to the output machine, and By combining the signal of the one date group AG display mode and the AND condition, one shot is generated as a timing signal only on the signal line of the corresponding display mode of the corresponding machine code.) A? Rus occurs. In the figure, AO, A1.
A2. A3. ....

D2. D3 is a timing signal of a signal line corresponding to the position display of car A to the call information of the 9th to 16th floors of car D, respectively.

FIG. 5(b) shows a circuit corresponding to each display data portion of the control information display 1, and the display data output from the group management control device 2, tP-) OUT2, is as follows. Each display LED (light emitting diode) group is connected to an input terminal of a latch circuit group LT preceding the LD. Then, due to the edge of the change in the one-shot pulse of the signal line that corresponds to the machine code and display mode specified by the output of the output port OUT 1 mentioned above, the display data of OUT 2 output at the same timing as 0UT1 is changed to the corresponding one. The display data is latched by the latch pulses (AO to D3) input to each CK terminal of the latch circuit group LT and rewritten to new information. Therefore, the group management control device 2
However, by changing the car code and display mode at regular intervals, the display data of each display mode of each car is updated to new data in a constant cycle. That is, if the group management control device 2 operates normally and the update cycle is performed within a certain period of time, the control information display 1 operates normally and can display information in real time.

In this way, various signals of each unit related to elevator group management control can be displayed centrally, so the operating status of each elevator can be clearly determined in real time, and therefore centralized operation can be easily performed. Maintenance such as adjustment and inspection of elevators can be performed easily. Work can be easily and efficiently saved.

Furthermore, by displaying the control information for each unit based on the information transmitted to the group management control unit that controls multiple elevators, it is no longer necessary to provide individual terminals, lines, etc. for each individual control unit. Therefore, it is possible to create a system that is efficient and very advantageous in terms of total cost.

In addition, by outputting and displaying from the same output port of the group management control device, the number of connection lines can be reduced, compatibility for each system can be achieved, and the display part can be carried with a computer. It also has the advantage that it has a configuration that allows the system to operate as a whole, and that it has little effect on the operating state of the entire system, which also makes it possible to reduce maintenance costs.

Note that the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without changing the gist thereof.

For example, in the above embodiment, the display data output signal from the group management control device 2 to the control information display 1 was explained as a parallel 1-byte signal, but this is in the form of a serial output and the display data is output in parallel on the display 1 side. It is also possible to convert the data into a file and provide it for display.

〔Effect of the invention〕

According to the present invention, it is possible to provide a control device for a group management elevator that can centrally display various control information related to elevator operations with a simple configuration.
