Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator signaling device, and is particularly effective in reducing the number of wiring within a tower on the landing side.

Usually, a car position display device and a hall call registration device are provided at the landing on each floor. Generally, a car position display device is equipped with an indicator light indicating the car position and a direction light indicating the driving direction, and a hall call registration device is equipped with a push button for an up call, a push button for a down call, and their response lights. These are connected to the elevator control system in the machine room by signal lines placed inside the tower from each landing.

Therefore, with this conventional wiring method, as buildings become taller these days, the number of wires inside the tower on the landing side becomes enormous as the number of floors increases, which increases the cost of wire materials and makes wiring work difficult. This will lead to an increase in installation costs.

The present invention has been made in order to eliminate the above-mentioned drawbacks.The purpose of the present invention is to provide a signal device that can reduce the number of wires inside the tower and that can be easily installed.

The most distinctive feature of the present invention is that a landing control device equipped with a microcomputer is provided at each landing on each floor. By doing this, signals can be sent and received between the elevator control device and side of any floor and machine room via the landing control device of each floor in between, and the number of wiring inside the tower can be kept to the minimum necessary regardless of the number of floors. can be kept to a limit.

Hereinafter, an embodiment in which the present invention is applied to an 8@ building will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing the overall configuration of the present invention, with some intermediate floor portions being omitted. In the figure, 1 is the elevator control device installed in the machine room, H1 to H8 are the hall control devices installed on the 1st to 8th floors, respectively, and 01 to C8 are between the hall control devices or between the hall control device and the elevator control device. A1 to A8 are call signals from the hall push buttons (not shown) on the 1st to 8th floors, respectively, and B1 to B8 are outputs to the hall display devices (not shown) on the 1st to 8th floors, respectively. It's a signal. FIG. 2 shows an internal block diagram of the hall control device H8 provided on the 8th floor, and the contents of the hall control devices on other floors are exactly the same. In the figure, 6 is a microcomputer, 7 and 9 are receiver circuits, and 8.5t.10X is a driver circuit. O12 is a synchronization signal for synchronizing signal transmission and reception between the elevator control device 1 and the hall control device H8 on the 8th floor.
input to the terminal. SF3 is a selection signal for selecting the 8th floor. DN13 is a command signal for giving the car position and driving direction to the hall display device on the 8th floor, and is sent from the elevator control device 1 to the microcomputer B via the receiver circuit 7. is input. OL7 is a synchronization signal for synchronizing signal transmission and reception between elevator control device 1 and hall control device H7 on the 7th floor, SF3 is a selection signal for selecting the 7th floor, and DN7 is a synchronization signal for synchronizing the signal transmission and reception between the elevator control device 1 and the hall control device H7 on the 7th floor.DN7 is a synchronization signal for selecting the 7th floor. These command signals are sent from the microcomputer 6 via the driver circuit 10 to the hall control device H7 on the seventh floor. DT7 and DT8 are signals indicating the presence or absence of a hall call for each floor.
8 to the elevator control device 1. Third
The figure shows a timing chart of each of the above signals.

Next, the operation of the above configuration will be explained. First, a synchronizing signal CL8 is issued from the elevator control device 1 to the hall control bag NH8 on the 8th floor, and is input as an interrupt signal to the microcomputer 6 via the receiver circuit 7.
An interrupt program that is started at the rising edge of 8 inverts the state of the corresponding output port, outputs '1' and starts a built-in timer. Then, when this timer times up, the state of the output port is inverted again. “0”
shall be. In this way, the synchronization signal C similar to the synchronization signal OL8
L7 is obtained and sent to the hall control device H7 at 7@ via the driver circuit 10, and this process is repeated one after another until the synchronization signal reaches the hall control device on the first floor.

Next, the elevator control device 1 sends a synchronizing signal qL8 to select the 8th floor, as shown in the timing chart of FIG.
The selection signal SE8 is set to “1” for 5 clocks of
A 5-bit command signal DN+3 for the 8th floor is sent at a rate of 1 bit δ lock. Here, the command signal DNS is 5
Since the building is on the 8th floor, we used 5 bits for the car position, 1 bit for the driving direction, and 1 bit for whether or not the hall call answering light can be reset. It can be arbitrarily determined depending on the number and amount of information to be transmitted. While the selection signal SE8 is 1 in synchronization with the synchronization signal OL8, the microcomputer 6 of the hall control device H8 of 8@ receives the command signal DN8 via the resino circuit 7, and sends it to the resino circuit 11. The signal is converted into signal B8 and outputted, which activates the hall display device on the 8th floor. At the same time, in synchronization with the last two clocks during which the selection signal S]lCB is <1", the driver circuit 8 is transmitted to the elevator control device 1 via the 8th floor selection signal SK8.
becomes "0〃" and the signal transmission and reception between the elevator control device 1 and the hall control device H8 on the 8th floor is completed. Next, the selection signal SE7 of 711M becomes // 1 // and this time the hall control device on the 7th floor Signals will be exchanged between H7 and the elevator control device 1. That is, 7
The floor selection signal SE7 is set to "1" and output via the driver circuit 10, and the contents of the command signal DN8 representing the car position and driving direction are sent as DN7 to the hall control device H7 on the 7th floor. The content of the signal DT7 indicating the presence or absence of a hall call is sent as is to the elevator control device 1 as DT8, and while the selection signal SE7 is "1", the signal exchange between the hall control device H7 of 7wI and the elevator control device 1 is performed. is performed via the hall control device H8 on the 8th floor.

In the same manner, the landing control device on a certain 1st floor uses the command signal series sent via the 1011th floor and the signal indicating the presence or absence of a landing call on its own floor to use the car position display device on its own floor or respond to the call. The command signal series to drive the lights and send to the 1-1st floor, and 1
A hall call information signal sequence from the 1-1st floor to be sent to the +1st floor is generated, and after this is performed sequentially up to 1@, the above operation is repeated again from the 8th floor. In this way, information can be transmitted between the elevator control device in the machine room and the hall control device on each floor using a small number of signal lines.

Although the above explanation has been made using an example of an 8-story building, the present invention is of course not limited to this. For example, if the selection signal is set larger than the 5 clocks in the above example, the invention can be applied to buildings with even higher floors. Further, the information sent from the elevator control device to the hall control device is not limited to the car position or the driving direction, but may be an arbitrary character string code.

Further, although an example has been shown in which the synchronization signal is input to the microcomputer as an interrupt signal, it may be a normal input without using an interrupt, depending on the processing capacity of the microcomputer.

Further, in order to ensure synchronization, a synchronization signal that becomes 1 only at the beginning of the clock for the lowest to Fth floor etc. may be added.

In addition to the clock period assigned to each floor, a clock period may be provided for transmitting and receiving common information to each floor.

Furthermore, the synchronization signals CL7 and CL8, or the hall information signals DT7 and Ijr8 are transmitted via the TEHA microcomputer 6 of the above embodiment, but since their contents are the same, these signal lines are It is also possible to short-circuit and adopt a so-called wired-OR configuration.

As described below, according to the present invention, the number of wiring inside the tower on the landing side can be significantly reduced, and the installation work can be easily performed.

Further, according to the present invention, the number of signal lines can be fixed regardless of the number of floors and the amount of information transmitted, and therefore, it is possible to diversify the boarding area display (for example, digital indicators, voice response, etc.)
This can be handled without changing the configuration of the signal line.

Furthermore, the cable length can be fixed regardless of the floor spacing, and by using connectors, the wiring work becomes easier and the number of installation steps can be significantly reduced.
