Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an elevator call registration device.In recent years, elevator control f! To Cao! Small scale calculators such as Icrofunhieta began to be used.

A pigeon drive using a small computer as an elevator control device.

To remember the elevator call, call 411#gI.
EiI! Two methods are considered: a method of storing data by providing a memory circuit made up of 1i80R, etc., and a method of storing data in a storage unit of a small computer.

The former method uses a special storage device outside the small computer, so it is disadvantageous in that it is relatively expensive.At the same time, when erasing the calls stored in the storage device, an erase signal is issued. It is necessary to provide an interface between the small computer and the storage device, but there are many disadvantages in configuring the entire 11 fathom control reconnaissance.The latter method is suitable for small computers! , it is only necessary to store it in the storage unit, and even if you want to delete the memorized call, you only need to replace the data in the storage unit, which has many advantages over the former method in terms of cost and processing. The latter method is generally used. Figure 081 shows a schematic configuration of a circuit for storing a call input signal in the storage unit of a small computer used in an elevator control device.

In FIG. 1, 26 to 2a are the floors at which the elevator stops.

Alternatively, when the call button is pressed at the contact point of the call button provided in the elevator car, the 191 call input signal is transmitted to the small computer 4 via the call registration Mf device 3, and the processor 4a in the small computer 4 is operated. The result is stored in the memory record tllN 4b, and further outputted via the output circuit 5 by operation of the processor t4g, and the call registration indicator light 6 is turned on.

The nine calls that are registered and remembered as described above are stored in the storage unit 4 by the operation of the Pro Dragon Tuna 4- using an input/output control signal (not shown).
The data in b is changed and erased, and at the same time, the call registration indicator light 6 is turned off via the output circuit 5.

FIG. 2 shows a circuit of a call registration device for storing calls in the storage unit of a conventional small-sized computer.

In Fig. 2, 1 is the call button, 2 is the contact point of the call button, and 7a~
7C is a limiting resistor, 8 is a photocoupler, 9 is a logic gate buffer circuit, 10 is an output signal, and when the elevator user presses the call button, its contact 2 comes into contact.

The call input bias -f1 is isolated and transmitted via a photocoupler 8, and further outputted as an output signal 10 via a limiting resistor 7b and a logic gate buffer circuit.

However, in the conventional call registration device, the call input signal is transmitted to the small computer only while the welfare call button is pressed, so if the time the call button is pressed is shorter than the calculation processing time of the small computer. In recent years, there have been frequent problems in which the call input signal cannot be stored in the storage unit of the small computer.

In recent years, the operability of pushbutton switches used for elevator call buttons has improved, and the contact responsiveness of the contacts has also improved significantly. There was a gap of 6, and the above problem occurred.

In particular, in smoke-controlled elevators, each elevator control device automatically selects one elevator from among multiple elevators and puts it into service in response to a single hall call for a stopping floor. Because of the time lag in the arithmetic processing steps of the small computer, the storage status l of the above-mentioned call input signal in the storage unit may be different for each elevator.

Group management control was rarely disrupted.

The present invention has been made in consideration of the above points, and is an elevator call f which can reliably store a call input signal in the storage unit of a small computer even if the operation time of the call button is extremely short.
This company provides a recording device.

The present invention will be explained below.

An embodiment of the elevator call registration device of the present invention is shown in the wXs diagram.◇ In Figure 3, 1 is the area source, 2F! , call button contact, 7
α to 7c are limiting resistors, 8 is a photocoupler, and the above structure and operation are the same as the conventional ones. 11 is a one-shot multi-pipe rake circuit, and the output duration is set to be longer than the arithmetic processing time of a small computer. 12 is a signal time securing circuit 13 configured with one or more OR circuits of logic gates.
1 is a newly added circuit according to the present invention, and 10 is an output.

FIG. 4 is a diagram showing a time chart of the elevator call registration device shown in FIG. 3. @4 Figure (a) is a time chart showing the state of the output 11g of the one-shot multi/(ibrator 11) shown in the same Figure 3. .

The following describes the operation of the elevator call registration device shown in Figure 1iI3 and the time chart shown in Figure 4 below. 12 dawn.

When the elevator user presses the call button, the contact point 2 comes into contact with the call button, and the call input signal is transmitted insulated via the photocube 5-8 to obtain an output f3a. The output 8g of the photocoupler 8 becomes the input signal 13g of the signal time securing circuit 13 via the limiting resistor 7b, and the one-shot multivibrator circuit 1
1 and input to the OR circuit of the logic gate. The one-shot multi I (ibrator circuit! 1 operates inverted at the 9 time point tj of the rise of the output 8a shown in FIG. 4(a) of the photocoupler 8 described above, and the duration time shown in FIG. 4(b)). T
, is input to the OR circuit 12 of I11 Rigenit. The OR circuit 12 of the logic gate is the cocoon of the photocoupler 8 described above (output 8g shown in -, and one 7).
Since it is operated by the signal of one or both of the outputs 11@ shown in FIG. 4(b) of the B-cut multivibrator circuit 11, the same continuation as the output 11g of the one-shot multivibrator DoM11 shown in FIG. 4(ω) Time check T
, generates an output 10 of .

In Figure M4 (α), the duration T of the output 8α of the 7 auto coupler 8 is equal to the contact duration of contact 2 when the elevator user presses the call button, that is, the duration of the call input signal, and therefore the one-shot multivibrator The duration time of the specific output 11 shown in Figure 4(b) of the circuit 11 may be longer. In this case, the OR circuit 12 of the logic gate is 11
It will last for a while.

Therefore, the output 10 of the signal time securing circuit 13 can continue to be output for a time longer than the duration 71 of the output 11g of the one-shot multivibrator circuit 11 even if the duration TI of the call-in chi 5 is extremely short. .

FIG. 145 shows another embodiment of the elevator call registration device of the present invention. In FIG. 5, 1 is a power supply, 2Fi nominal button contacts, 7α to 7C are limiting resistors, 8 is a photocoupler, and 9 is a logic gate buffer circuit, and the above structure and operation are the same as the conventional one. Reference numeral 11 denotes a one-shot multivibrator circuit whose output duration time is longer than the arithmetic processing time of a small computer. 12 is a signal time securing circuit 13 configured with one or more logic gates oa@g, which is a newly added circuit in the present invention, and the above configuration and operation are similar to the signal time securing circuit 13 shown in FIG. Similarly, the elevator call registration device of the present invention shown in FIG. In the call registration device, it is connected to the output side of the photocoupler 8, whereas it is connected to the input side, and the effect is the same.

As described above, according to the elevator call registration device of the present invention, a small computer is used to input the call number to the storage unit. In an elevator control device that memorizes the call number, even if the time the operator is pressing the call button is shorter than the arithmetic processing time of a small computer, the output duration newly added by the present invention is small. Calculation processing of the computer - By the action of the one-shot multivibrator circuit and the OR circuit of the logic gate, which have a cycle time or longer, it is possible to reliably store the call input signal in the memory unit of the small point calculator, and it is possible to swm the elevator
Even in the case of control, there is no benevolence that causes disturbances in control.
