Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a call generator for an elevator machine room that allows a control means to register a call for any floor in the elevator machine room.

A car call command to call an elevator car is generally issued to the control means from a call button device installed on the landing wall of each floor. May be emitted from the machine room. This is because during maintenance and inspection, it may be necessary to move the car to a predetermined floor in the machine room.

A device for generating a call command in such a machine room is a call command generator for the machine room of an elevator.

In the past, there was no independent call generator for the machine room, and the call command was generated from the machine room by one of the following methods.

(1) If there is a call registration relay corresponding to the call button device on each floor in the machine room, manually open or close the armature of the optional relay.

(n) If the call button equipment on each floor is connected to the control means consisting of a microprocessor by a separate wire, and the machine room has an entry point for the wire of the control means, for example by a jumper wire. Set either of the inlet portions to a predetermined potential.

However, recently, with the aim of lowering the cost of devices, there has been a trend toward simplifying devices by reducing the need for sharing cables and other elements, and configurations such as those in cases (1) and (I[) above are no longer being used. In recent years, a structure has been developed in which the call commands from each floor are encoded and transmitted to and received from the control means via one or a few cables.

Therefore, generation of the call command in the machine room requires a method using a code signal different from the method described above.

The call generator for the machine room of an elevator according to the present invention has been developed to meet this need for handling.

The present invention will now be described with reference to the accompanying FIGS. 1 and 2. FIG.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, (1) is a central processing unit (hereinafter referred to as
(referred to as February), (2) indicates each floor (the one shown is the 1st floor to the 6th floor), for example, a code consisting of binary + code (
No. 8 to the CPU (1) via the interface (8)
This is a rotary switch that is the floor setting means that sends out signals to the floor.

In the figure, (4) is the main memory (hereinafter referred to as "memory") of c p (
A call registration generation switch (hereinafter abbreviated as "registration switch") that issues a registration timing signal to cause the registration switch (5) to perform the storage operation), and the signal from the registration switch (5) is sent to the cP via the interface (6). U (1) and c p U (1)
When the signal is received, the call is registered.

Furthermore, in the figure, (γn) is a latch circuit that receives a command sent from CPU (1) when the floor corresponding to code (8) is registered, and (8) is a latch circuit (
7) is a display device made of, for example, an LED, which is lit during the latch period.

FIG. 2 is a flow chart showing the operation of generating a car call command and the operation of registering a car call in the embodiment apparatus having the above configuration.

The operation will be explained based on the flowchart.

First, the CPU (1) reads a code signal indicating the floor set to the rotary switch (2) (the one shown indicates the 5th floor, so for example, '1011) through the ink face (3) ( Step 1). Next, the CPU (1) checks whether the registration switch (5) is on or off and performs step 2.
), if it is in the on state, the call is written in the address corresponding to the above code signal in the memory (4) (step), and the process proceeds to the next step; if in the off state, the process proceeds directly to the next step. That is, the content of the address corresponding to the code signal, that is, the registration status of the floor (51, etc.) indicated by the code signal is confirmed (step 4). Note that this step is necessary because, in addition to registration by turning on the registration switch (5), registration can also be performed by turning on a call button device provided on each floor. As a result of the confirmation in step 4, if it is registered, the CPU (1) sends a command to the latch circuit (γ) to turn on the display device (8), and if it is not registered, the above-mentioned step Return to 2.

Of course, the CPU (1) moves a car (not shown) based on the registered contents of the memory (8).

The operations of the maintenance and inspection personnel performed in parallel with the operations of the above-mentioned machine room call generator will be described below.

The maintenance inspector sets the pointer of the rotary switch (2) to the floor number for which car call registration is desired. After this, check whether the display device (8) lights up or not. If it lights up, there is no need to take any further action as the call registration for the floor has already been made, and on the other hand, it does not light up. If so, turn on the registration switch (5). This completes the car call registration.

As described above, according to the apparatus of the present invention, a maintenance/inspection person can easily perform call registration from the machine room.

Further, according to the present invention, it is possible to cope with changes by applying a code signal of a call command generation configuration provided on each floor.
