Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device using a computer, and more particularly to an elevator control device for controlling by multiplex data transmission.

[0002]

2. Description of the Related Art The amount of information handled increases with the diversification of elevator service contents, and the number of wires between the hall call registration device and the elevator control device main body installed at the landing of each floor has increased remarkably.

Therefore, various proposals have been made in order to reduce the number of wirings. It is said that the input / output terminal device on each floor is provided with a microcomputer to reduce the number of wirings by performing serial data transmission. A proposal has been made, and an example thereof has been disclosed in JP-A-61-6967.
It can be found in Japanese Patent Laid-Open No. 7 and Japanese Patent Laid-Open No. 61-194943. Proposal to reduce the number of wires and transmission time by dividing the transmission of input / output of individual information (hall button, response lamp) for each floor and the transmission of information common to each floor (indicator, etc.) Is disclosed in JP-A-64-43478.

[0004]

In recent years, in order to prevent passengers from being confused by giving unnecessary information to passengers in the car position display for indicating the current position of the car to the passengers in the halls on each floor by lighting a lamp, etc. Reservation IN that displays the car position only on the floors that served
D system is increasing.

FIG. 3 is an explanatory diagram for explaining a conventional reservation IND method.

As shown in the figure, in the above-mentioned prior art, the wiring is directly made from the I / O unit of the host controller in the machine room to each floor, and in order to display the car position for all floors on each floor. The number of wirings for all floors is required, and at least wiring for all floors × all floors is laid from the I / O unit. In the example shown in FIG. 3, there are 24 points because 8 points of information other than the 16th floor are displayed. In this way, there are problems that the number of wires is large and the burden of on-site construction is heavy and that maintenance is troublesome. In addition, in the conventional serial data transmission technology, it is necessary to individually transmit whether or not the car position is displayed on each floor, and if the number of input / output terminals on each floor increases, the amount of individual transmission increases, and Not only increases the transmission time, but also limits the number of I / O unit outputs.
This is a big limitation when there are many floors, such as the 50th floor and the 60th floor, as in a skyscraper. In order to solve this, the transmission speed itself should be increased, but considering the environment where the elevator is actually installed, it is preferable that the influence on noise is small. In this respect as well, if the transmission speed is set too high, it is likely to be affected by noise, and thus there is a limit to the increase in the transmission speed. There is also a problem that changes such as increasing the clock frequency of existing hardware are required to increase the transmission speed.

The object of the present invention is to solve these problems,
It is intended to reduce the number of wires between the elevator control device main body and the input / output terminal device.

[0008]

This is achieved by providing means for controlling information to be multiplexed and commonly transmitted.

The input from the input / output terminal control device is an assigned hall call input from the input / output terminal device by a passenger on a specific floor, and a plurality of information included in the common transmission / reception processing specification is input by the passenger in a hall call. The indicator lighting specifications and the car position information on the floors and the indicator off specifications on the floors where the assigned hall call is not input, and the storage destination information of the common transmission reception processing specification is the reception storage of the common transmission reception processing specification. It is desirable that the reception storage permission information specifies the floor permitted by the operation mode control means.

The operation mode control means refers to the reception storage permission information included in the information transmitted from the host control device, stores the received operation mode control means if there is storage permission, and stores the storage permission. If there is not, it is desirable to provide a means for not storing.

It is preferable that the reception storage permission information has information about all floors of the operation mode control means connected to the bus.

[0012]

According to the above construction, when the passenger calls the assigned hall to the input / output terminal device of a certain floor and the reservation IND system for displaying the car position of the elevator is performed,
The host controller specifies to the transmission controller the storage location of the indicator lighting specifications (specific floor where the assigned hall is called) and the storage location of indicator off specifications (other floors where the assigned hall is not called), and the car position information Is output.

The transmission control device transmits reception storage permission information for permitting reception and storage of indicator lighting specifications and indicator lighting specifications for instructing lighting of the indicators to all floors only on the floor designated by the host control device.

The operation mode control means provided in the input / output terminal control devices of all floors receives the same reception / storage permission information and indicator lighting specifications, but only the floor designated by the host control device receives the indicator lighting specifications. Is received, and the input / output terminal device is controlled to light the indicator according to the indicator lighting specification. Since the other floors are not permitted to receive, the indicator lighting specification is not received.

Next, the transmission control device transmits reception storage permission information for permitting reception and storage of the indicator erasing specification on the floor designated by the host control device to all floors and an indicator extinguishing specification for instructing extinction of the indicator.

The operation mode control means provided in the input / output terminal control devices of all floors receives the same reception / storage permission information and the indicator turn-off specification, but the floor designated by the host control device receives the indicator turn-off specification. Since it is permitted, the signal is received, and the input / output terminal device is controlled to turn off the indicator according to the indicator turn-off specification. Since the other floors are not permitted to receive, the indicator off specification is not received.

Next, the transmission control device transmits the car position information indicating the current car position to all floors.

Of the operation mode control means provided in the input / output terminal control devices on all floors, the input / output terminal device is arranged to display the car position by turning on the indicator only on the floor designated by the host control device. Control. Since the operation mode control means of the other floors controls the input / output terminal device so as to turn off the indicator, the received car position information is ignored.

The input / output terminal control device of each floor displays the floor where the current car is located on a specific floor which has been called by the operation mode control means, and an indicator on other floors where the assigned hall is not called. Turn off.

In this way, the indicator lighting specification, the indicator extinguishing specification, and the car position information are multiplexed and commonly transmitted by at least one common bus, so that the wirings laid from the host control device to the input / output terminal devices on the respective floors can be installed. Will be reduced.

Although the indicator turn-off permission specification is received in step 3, only the terminal control devices F102 and F103 other than the first floor are stored and the turn-off process is performed. However, since the terminal control device F101 on the first floor does not store the indicator turn-off permission spec, the lighting process is performed. Will remain. Next, as an input / output that is different for each floor, the output of the response light for each floor and the initials for individual transmission for the input of the hall button are provided to all terminal control devices F10.
1, F102, F103. In this example, the input positions of the hall buttons and the output positions of the response lights in each terminal control device F101, F102, F103 are the same on all floors, so all terminal control devices F101, F102,
The receiving and storing destination is designated in F103 and the individual transmission specification is transmitted. All terminal control devices F101, F102, F103 receive the specifications for individual transmission, and all terminal control devices F10

To do.

S130 Since the terminal control devices on each floor are connected in parallel to the bus, all the terminal control devices receive the lighting permission specification. However, referring to the reception storage permission data, the floor of the own station permits reception storage. Only when it is turned on, the lighting permission specification is stored and the terminal control device is initialized to perform the lighting control. If the reception / storage permission is not granted, the lighting permission specification is not stored and ignored. For floors that do not have a call in the assigned hall, set the inverted value of the reception storage permission data of the INJ lighting permission specification, and initialize the terminal control unit to perform the ING OFF processing. Send.

Since the terminal control devices on each floor are connected in parallel to the bus, all the terminal control devices receive the turn-off permission specification, but the floor of the own station is permitted to receive and store by referring to the reception and storage permission data. Only when there is a turn-off permission specification is stored, and the terminal control device is initialized so that it can be turned off. If reception / storage is not permitted, the turn-off permission specification is ignored without being stored.

S140 Next, the individual transmission initials regarding the output of the response light for each floor and the input of the hall button are performed for the terminal control devices on all floors. Generally, the relationship between the input position of the hall button and the output position of the response light in each terminal control device is the same in the terminal control devices on each floor, so the reception storage permission data and individual transmission specifications are sent to all terminal control devices. To do.

Since the terminal control devices on each floor are connected in parallel to the bus, all the terminal control devices receive the individual transmission specifications and refer to the reception / storing permission data. , The specification for individual transmission is stored, and the terminal control device is initialized to perform individual transmission processing.

S150 The transmission control device M12 sends information representing the floor name of the first floor, and further sends information to the first floor.

Terminal control devices F101, F102 on each floor,
F103 collates the floor name transmitted on the bus with its own floor name, and ignores the transmitted information if they do not match. When they match, the information is received, and floor information such as call button information of itself is transmitted to the transmission control device M12, and the transmission control device M12 receives this.

S200 The transmission control device M12 receives the information from the terminal control device F103 on the third floor.

Thereafter, the procedure of transmitting and receiving these is performed from the fourth floor to the nth floor.

S210 The transmission control device M12 transmits information from the terminal control device F10n on the nth floor.

S220 The transmission controller M12 receives the information from the terminal controller F10n on the nth floor.

S230 Further, inge data is transmitted as information common to all floors.

Since the terminal control devices on each floor are connected in parallel to the bus, each terminal control device receives indication data common to all floors. The terminal control device, which is stored and initialized with the lighting permission specification, performs lighting processing on the received indicator data. (The inge data input to the inge data input table is output to the I / O of the indicator.) Further, the terminal control device which is stored and initialized with the extinguishing permission spec, extinguishes the received inge data (inge data The indicator is turned off by performing the output data to the indicator without using the ink data input to the input table of. Thus, the procedure for one cycle is completed and the process returns to the first step S100. Further, since all the terminal control devices are connected to the common bus line in an array, even when one terminal control device cannot transmit due to a failure or the like, another terminal control device can perform transmission.

As described above, according to this embodiment, the following effects can be obtained.
