Description

DETAILED DESCRIPTION OF THE INVENTION (Background of the Invention) The present invention provides a signal distribution system connected to the operation of an elevator that informs elevator users of the status of the elevator. Concerning procedures and elevator call button stations.

Elevators have as integral components the call button required by the user and various signal lights indicating, for example, the location of the elevator and the arrival at the called floor. These functions must be provided on each floor and often form a single unit, hereinafter referred to as a call button station, mounted behind a single metal plate. On the other hand,
The elevator controller to which the call is directed and which controls the elevator motor is typically mounted on top of the elevator shaft within the motor cubicle. Thus, modern control systems are completely electronic and consist of electronic components assembled on circuit boards, usually within the equipment panel or the main control panel of the elevator system.

I had to wire the pushbutton switch and signal light included in the Moderna call button station between the peripheral panel and the main control panel, but I realized that if I ran the lead wire bundle from each floor to the main panel, it would become completely tangled. I want to be Providing such wiring bundles requires careful planning and a great deal of preparation, especially as the number of floors and characteristics of the call button stations change, since in many cases individual wiring must be done. Therefore, the central panels of the elevator must be designed one after the other.

(Objective of the Invention) The object of the present invention is to avoid the above-mentioned drawbacks, only require 2 to 3 wirings, all the elements that control the operation can be manufactured as standard products, and the only thing that needs to be done by the installer is programming. Located in providing elevator signal system.

In order to obtain such an elevator signaling system, the present invention proposes that an elevator call is received, forwarded, and the status of the elevator is described using a microprocessor installed at each floor, realizing a bidirectional series draft. It is characterized by

The essential result of such a procedure is that the wiring of the call button station is significantly reduced due to the serial traffic principle. Another advantage of processor operation is that installation is flexible because different types of call button stations can be operated with the same standard assembly if properly programmed for different situations.

In terms of mass production, for example, the use of mask-programmed "single-chip" processors is far superior to traditional signal systems that include redundant wiring.

One advantageous embodiment of the present invention requires that elevator calls be processed and put into the form required for the various functions of the elevator on each floor's microprocessor when necessary. This is a necessary prerequisite to obtain a flexible signaling system in which the information can be easily processed at each point into the required form.

One advantageous embodiment of the inventive procedure is such that the serial traffic between the processors is directed to one of the microprocessors in the control unit or to the level processors at each floor, and that this main processor takes its place and sends the J:l:l examines the state of one level processor at a time and changes from receiving mode to sending mode when that level processor receives a corresponding query addressed to it. The device is characterized in that it sends the requested information to the main processor, and then changes to the receiving mode. This type of simple line procedure can be handled by any single-circuit microprocessor while simultaneously preserving the signal for the user.

A call button station applying the inventive procedure comprises at least one level processor connected in such a way that the call button station is in serial traffic with other call button stations, the call button station also having a signal with said push button. It is characterized in that means are connected to each other, by means of which the elevator status is signaled both to the control device of the elevator and to its user. If several elevators are running side by side in an elevator shaft, they can either share the level processor of one level or each can have its own level processor.

An advantageous embodiment of the call button station according to the invention is such that the number and type of signaling means in the call button station as well as the control devices and the necessary data regarding each floor can be programmed by the installer and incorporated into the level processor. It is characterized by the following. Providing this method is nothing more than, for example, installing a mechanical switch across the terminal comprising the microprocessor and having the level processor determine the value of each parameter by means of a mask program based on its position.

One advantageous embodiment of the call button station according to the invention provides that the push button station in the elevator car has a processor of the same type as the level processor of the call button stations of the various floors, said push button station The driving command is configured to send driving commands received from the level processor to the serial traffic bus of the level processor. In this way, in addition to the power supply lead, only one lead is required for the data transfer of the controls originating from the elevator car.

One advantageous implementation of the call button station according to the invention is characterized in that the signaling means of the push button station in the elevator car are arranged to give the necessary announcements to the passengers in the elevator car from the serial traffic bus. shall be. Two-way communication between the elevator car and the control device is required, for example, in connection with a service or when the elevator is operated by a guide.

The invention will be explained in detail by way of example and with reference to the drawings.

(Description of a preferred embodiment) FIG. 1 shows a main processor l and two level processors 2a.
and 2b, and a serial traffic bus 3 interconnecting all the processors in the system. All level processors are the same. The main processor can be one of the same level processors, or it can be a separate microprocessor embedded on the elevator's main control panel. Although the main controller is shown as separate here, it has logical connections to the power electronics unit that drives the elevator motor through relays and other control circuits. This power electronics unit may be of any type suitable for the purpose. However, it is not shown in the drawing. Series traffic bus 3 (consisting of 13 leads)
! tl, the power supply pair (0 and +5V) and the traffic bus itself ([Signa]-J).

Although FIG. 2 shows one level processor 2, it is in contact with a considerable number of elevator signal peripheral surfaces gf. The push buttons 4 are elevator call buttons, one for ascending and the other for descending. Lamp 5 is a signal light that lights up when the elevator reaches its destination floor.
Lamp 6 indicates that the elevator is out of service.

The circuit 7 is a parallel input/output circuit and controls the hour display circuit 8. The direction in which the elevator moves is indicated by a signal light 9. The loudspeaker IO announces that the elevator has reached the destination floor. This allows, for example, visually impaired people to know when the elevator has arrived. It is also possible to program the processor to output other audio signals.

The junction box 11 can also be used to program the level processor with data for each individual device. These data are primarily of the type that relate to the number and type of equipment in the level processor oil production environment.

In other words, the processor is informed of the configuration of the call button station. Information about the floor number, elevator location, and all other system data are entered into the elevator's main panel by programming them into the main processor.

Serial traffic on bus a proceeds as follows.

When the elevator call button 4 is pressed, a flag in an internal register in the microprocessor 2, which operates as a level processor, is set. It should be noted that the normal state of the level processor is [signal
On the J line, it is in the input state, ie, in the receive mode. Thus, the controller's processor inquires or polls the status of each level processor in turn. When the level processor knows that a question is being asked of it, it changes its state from input to output, or send mode.

At the same time, the main processor is switched to manual mode.

The level processor being polled provides the contents of its registers in serial form to the acknowledging main processor. Both processors then change state again. The same is then repeated for the next level processor in a similar manner. When a call is occurring, the main processor recognizes the contents of the respective level processor registers as a call and sets its output line towards elevator call a "4" so that the elevator motor follows this new call. .The main processor's query flu i:Fv is hardly interrupted by this, but rather runs the routine (.1!).

Those skilled in the art will clearly recognize that the scope of the invention is not limited solely to this example.

Various embodiments may be made within the scope of the claims.

For example, the number and type of functions that can be tied to a call button station is in no way limited. The work and control of the level processors serving passengers can also be increased or decreased as needed. In addition to data transfer, the level processor processes information and can be refined into forms such as elevator motors. Such functions include motor bank control and other logic and fault detection conditions required by the elevator.
