Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an elevator call registration device, and is particularly applicable to shared elevators in residences, rental offices, etc. that can only be used by specific people during a certain time period. The present invention relates to an elevator call registration device with call registration regulation suitable for cases where the user wishes to do so.

[Background of the invention]

Conventionally, as a means of regulating the call registration of shared elevators, as described in Japanese Patent Laid-Open No. 58-22272, a method has been adopted in which the call registration is disabled using a key switch or the like so that the general public cannot operate it. was.
However, the above-mentioned conventional means has the inconvenience of being unable to use the elevator unless the user always carries the key. In order to eliminate this inconvenience, a coded call registration system in which a numeric keypad is installed at the landing or a coded registration system in which a dummy button is installed in the car is beginning to be adopted. However, these methods also require special keyboards and buttons for cryptographic operations, which not only leads to increased prices, but also the fact that cryptographic operations are necessary can be detected from extra numeric keypads installed. There was a risk that the encryption method could be stolen by an unspecified passenger.

Furthermore, without installing a new special keyboard or button, it is possible to perform a code input using a specific operation procedure of an existing call button and perform a prescribed operation, for example, as disclosed in Japanese Patent Application Laid-Open No. 56-88077, It is publicly known from Publication No. 52-44943.

However, as the device becomes more complex, code input may be detected or accidentally registered, so it cannot be said to be sufficient for crime prevention.

[Purpose of the invention]

An object of the present invention is to solve the above-mentioned problems in the prior art by providing a switching means for switching elevator operation between "general" mode without call registration regulation and "crime prevention" mode with call registration regulation. To provide an elevator call registration device which is inexpensive and whose operating method is difficult to detect by unspecified passengers, which can regulate call registration only by operating a conventionally installed button for crime prevention.

[Summary of the invention]

The present invention includes a switching means for switching the elevator operation between "general" and "crime prevention", a call registration means for calling a car by operating a hall button during the "general" operation, and a destination during the "crime prevention" operation. A call registration means that calls the car by repeatedly operating the hall button the same number of times as the number of floors and holding the button down for a predetermined time at the final time, and designating the destination floor by using the car tongue during this "crime prevention" operation. Means is provided for enabling only the destination floor corresponding to the number of times the hall button is repeatedly operated.

In other words, the hall button operation during "crime prevention"
A button operation method using already installed buttons by repeating the operation the same number of times as the destination floor and setting a longer operation time for the final operation, using two factors: number of times and time. In consideration of the possibility that a third party accidentally succeeds in registering a hall call using the hall button operation method described above, calls for specifying the destination floor after boarding the car will also be restricted from the previous hall. By regulating the operation in relation to the hall call operation, it is possible to reduce the cost by regulating the operation inside the car according to the operation at the hall, without having to encrypt it independently from the operation at the hall. It is possible to provide an elevator call registration device that is large and difficult to detect by unspecified passengers.

The content explanations for the graphic symbols in FIGS. 5 to 5 are shown.
In this embodiment, a case will be described in which a shared elevator has four floors, from the first floor to the fourth floor, and a call registration restriction is applied to the first floor hall button. The meanings of the letters and symbols in the diagram are as follows.

I will invest in it.

UP…Direction relay that detects the above operation DN…Direction relay to detect descending operation Next, the operation of the embodiment will be explained.

First, the call registration operation in "general" mode will be explained. Since the changeover switch SW is installed on the ``general'' side, the ``crime prevention'' call registration changeover relay CHR is released. In this state, for example, if a passenger who wants to board from the 1st floor landing presses the ascending hall button 1U, the 1st floor ascending hall button auxiliary relay BR is turned on, which turns on the 1st floor ascending hall call registration relay 1UR, and the contact 1UR Holds itself at ₁ , and 1UL of the response lights lights up to notify passengers that the call has been registered. When the car arrives at the first floor, the contact _1F3 of the position detection relay 1F is opened, the first floor ascending hall call registration relay 1UR is released, and the response light 1UL is turned off to notify that the car has arrived.
That is, the call operation in the "normal" mode is configured such that the call is registered immediately by pressing the hall button once, and this is the same operation as normal elevator operation without call registration restrictions.

Next, the call registration operation during "crime prevention" will be explained. First, the changeover switch SW is switched to the "crime prevention" side. This turns on the "crime prevention" call registration switching relay CHR. In this state, a case will be explained in which a passenger who wants to go from the first floor to the fourth floor, which is a crime prevention floor, comes to the first floor landing and performs the operation. As for the code operation, the first floor ascending hall button 1U may be repeatedly operated four times, and the fourth and final press operation may be performed for a long time (in the embodiment, the time exceeds 3 seconds). This operation will be described below. First, when the ascending hole button 1U is pressed for the first time, the auxiliary relay BR is turned on, which turns on the counter relay 1P, and the counter relay 1P self-holds at its contact _1P1 . Rising hole button 1U
When you release , the auxiliary relay BR releases, which causes
Counter relay 1R is closed, and counter relay 1R self-holds at its contact _1R1 . When the rising hole button 1U is pressed for the second time, the auxiliary relay BR is turned on, which turns on the counter relay 2P, and the counter relay 2P self-holds at its contact point _2P1 . Thereafter, by repeating the operation of releasing and pressing the rising hole button 1U, the counter relays 2R→3P→3R are sequentially turned on and self-held. Then, by the fourth push operation, counter relay 4P is closed and self-held. If you continue to press the button for the fourth time, timer TA will operate after 3 seconds, and its contact TA ₁ will close to turn on relay 4PH, which detects the establishment of the crime prevention call operation, and that contact 4PH ₁ will turn on the relay. 4PH is self-maintaining. As a result, the rising hall call registration relay 1UR
is input, and the following operation is the same as in the "normal" case described above. Furthermore, by turning on relay 4PH, the circuit including counter relays 1P to 4R for counting the number of repetitions is disconnected, invalidating subsequent cryptographic operations and preventing passengers from sharing the same train.

Once the car reaches the 1st floor, the process is as described above until the 1st floor ascending hall call registration relay 1UR is released.Next, the door opens and the car is registered for the car call specifying the destination floor after boarding the car. The operation will be explained. "Crime prevention" call registration switching relay
CHR, position detection relay 1F, and relay 4PH that detects the establishment of the crime prevention call operation are turned on, so 1
The CR to 3CR relay circuits are disconnected, so pressing the car buttons 1C to 3C will not register a call. Only one valid car button 4C
If you press , the car call registration relay 4CR for the 4th floor is turned on and self-held by contact 4CR ₁ . In this way, only the car call registrations for the same number of floors as the number of repeated operations are valid, and by performing double call restrictions for the landing area and inside the car, usage restrictions for foreign passengers are implemented.

Next, detection of erroneous operation during "crime prevention" will be explained. One of these is to detect an abnormally long time interval between repeated operations on the car button that specifies the destination floor as an erroneous operation.If the car button is not pressed again within 5 seconds after being released, the timer TB will start. , the relay ER is turned on to detect an operation error. This is designed in response to out-of-town passengers who press the car button thinking they can register their destination floor, but the elevator does not register, so they give up on using the elevator.

The other method detects repeated operations exceeding the maximum number of floors as an erroneous operation.When the button is released for the maximum number of presses, in this example, the fourth button is pressed. When released, counter relay 4
R is turned on, which causes the operation error detection relay to
ER throws in. This is configured as a countermeasure in case the car button is repeatedly operated unnecessarily.

When the operation error detection relay ER is turned on as described above, it is self-held at contact ER ₁ , and the timer TC, which temporarily regulates the next operation (for 5 seconds in the example), is turned on, disabling the repeated operation counter circuit, and at the same time turning off the flicker. It drives the device FR, flickers the hall button response light 1UR, and implicitly indicates that the cryptographic operation has failed. Operation error detection relay ER
is released when the timer TC counts for 5 seconds, the flicker display also stops, and cryptographic operations are made possible again.

Although one embodiment of the present invention has been described above, it is also possible to easily provide a plurality of floors with call restriction floors in a hall by simply adding the number counter circuit of this embodiment. Further, in the above embodiment, a relay circuit is used to make the explanation of the operation easier to understand, but in an elevator equipped with a microcomputer, these operations can be easily performed by the microcomputer.

[Effects of the Invention] According to the present invention, call registration can be controlled using only the hall buttons and car buttons that are the same as in the “general” mode even in “crime prevention” mode, and the control method is based on the number of repetitions at the landing and in the car. By using a cryptographic operation method that combines the double regulation of , the number of repetitions and the operation time,
It is possible to provide a call registration device for call regulation that is inexpensive and difficult to detect.
