Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cryptographic input type hall call registration device for an elevator.

[0002]

2. Description of the Related Art For security reasons, there is a method of operating an elevator in which only a specific person can use the elevator and general people cannot enter the building.

Conventionally, such a driving method is installed near a numeric keypad device or an entrance / exit of an elevator, and only a specific person is given a predetermined secret code number so that a correct secret code number can be obtained from the numeric keypad device. The method of activating the hall call button only when it was input was adopted.

As a method similar to this, an ID card reader is installed near the entrance of the elevator, and only the person who is permitted to use the elevator carries the ID card, and the ID card input signal is sent from the ID card reader. There is a method to enable the landing call button only when is entered.

Also, by mounting a key switch on the wall surface near the entrance of the elevator and inserting a key possessed only by a person who is permitted to use the elevator to turn on the switch, the hall call button is effective. There is a method such as

[0006]

However, such a method is unfavorable in design and tends to be disliked because a ten-key device, an ID card device, or a key switch is installed near the entrance of the elevator.

Further, in the method using the ID card reading device and the key switch, when the number of people who are allowed to use the elevator increases, it is necessary to prepare the ID cards / keys for the number of users, which is troublesome. There is.
Further, there is a problem that the elevator cannot be used if the ID card / key is lost or forgotten.

The present invention has been made in view of the above conventional problems. Since the hall call button is used as an encryption input device, the special keypad device, the ID card reader device, the key switch, etc. Eliminates the need to install additional equipment, eliminates design problems near the elevator entrance and exit, and also eliminates the need to prepare an ID card / key.
It is an object of the present invention to provide a cryptographic input type hall call registration device for an elevator, which can solve the problem that the elevator cannot be used due to loss of an ID card / key or the like.

[0009]

To achieve the above object, the present invention provides a storage means for storing a cipher, a cipher input means for inputting a cipher, and an inputted cipher stored by the storage means. In the hall call registration means for validating a specific hall call only when the ciphers coincide with each other,

A hall call button is used as the cipher input means, and means for analyzing the length of time the hall call button is kept pressed is provided, and a combination of the length of time the hall call button is kept pressed is inputted as a cipher. It is characterized by doing.

[0011]

The elevator cipher input type hall call registration device of the present invention has the following features:
When the time is longer than a predetermined time, it is long-pressed, and when it is short, it is defined as short-press and long-pressed, and the order and the number of short-presses are stored in the storage device as a code.

It is checked whether or not the hall call button, which is the cipher input means, is pressed at regular intervals, and the cipher judgment means judges whether it is a long press or a short press depending on the length of time the button is kept pressed, When the appearance order and the number match the above-mentioned code, the hall call for the floor is validated, but when they do not match, the hall call is invalidated.

[0013]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the present invention.
The call numbers of the hall call buttons 11 to 14 are input to the hall call input unit 20. The cipher hall storage unit 21 is a storage device such as a ROM, and stores a hall (hereinafter referred to as a cipher hall) in which a hall call can be registered only when a code is input and coincides.

In the hall call input unit 20, it is stored in the encrypted hall storage unit 21. The encrypted hall signal is transmitted to the cipher determination section 23, and the ordinary hall signal which is not the encrypted hall is transmitted to the ordinary hall call registration section 22. The normal hall call registration unit 22 registers the hall call signal in the hall call registration device 26 as a hall call.

On the other hand, the signal of the encryption hall is not registered as a call signal but is input to the encryption determination unit 23. In the cryptographic determination unit 23,
Counts the time that the input signal continues to be on (the hall call button is being pressed). If this time is longer than the predetermined time, it is determined as long press, and if it is shorter than the specified time, Is determined to be a short press.

Further, only when the order and number of long press and short press inputted from the hall call button coincide with the order and number of long press and short push stored in the encryption storage section 24, the code hall call registration is performed. A hall call registration request signal is output to the unit 25. Upon receiving the hall call registration request signal, the cipher hall call registration unit 25 receives the hall call registration device 26 as a hall call.
Register with.

The present invention is characterized in that the hall call button is used as an encryption input means, and a combination of the length of time when the hall call button is kept pressed is inputted as a code. To do.

Since the hall call button is used as a cipher input means and the length of time that the hall call button is kept pressed is treated as a cipher, it is determined whether the push button has been pressed or pressed for a long time as shown in 2a and 2b of FIG. To do.

2a of FIG. 2 is a time chart when the push button is pressed for a long time (is pressed for a long time). When the push button is on (pressed continuously) for t1 seconds (for example, 2 seconds) or more, press and hold. 2b in FIG. 2 is a time chart when the push button is short-pressed (short-pressed), and the short-time is when the push-button is on for less than t1 second.

Timer data t1 for determining long press and short press
Is a value sufficiently larger than the polling cycle of the hall call button signal, and is set to a value that can be sufficiently operated by a person (for example, if the polling cycle is 100 ms, t1 is 1 to 2 seconds).

As another example of determining the long press and the short press, the determination time data for the long press and the short press is not fixed as described above, but as shown in 2c of FIG. The time of the sections P1, P2, and P3 that were continuously pressed is stored, and the value obtained by multiplying the minimum value of that time by n times (n> 1) is long-pressed and calculated as the judgment time data for short-pressed. There is also a method in which a key that has been pressed for more than this judgment time data is pressed for a long time, and when it is not pressed for a short time.

In 2c of FIG. 2, P1 is 700 ms, P2 is 500 ms, and P3 is
If it is 1500ms, if n is set to 2, the judgment time data will be 500ms x 2 = 1000ms, short press P1 and P2,
P3 can be judged as a long press. Next, FIG. 3 is a cryptographic storage unit of FIG.
It is a figure which shows an example of the storage method when 24 is comprised by ROM etc. The number of digits of encryption is stored in the address a, and is 04 (4 digits) in this example.

Addresses a + 1 to a + 4 store the first to fourth digits of the cipher, and FF indicates a long press and 00 indicates a short press. Also, the 1st to 4th digits of the address are specified such that the a + 1 address is the 1st digit and the a + 2 address is the 2nd digit. In the example of FIG. 3, 4 digits are entered as the cipher. Then, it is set so that the call of the encryption hall cannot be registered unless it is input in the order of long press, short press, long press, and short press. It is possible to set different ciphers for each cipher hall, and this can be realized by providing the ciphers shown in FIG. 3 for each cipher hall and storing them at different addresses. Next, FIG. 4 shows a flowchart of an example of the process of the cipher determination unit 23 of FIG. This process is executed at regular intervals (for example, 100 ms) using a timer or the like.

First, it is judged whether or not the first digit of the cipher is accepted, and it is judged whether or not a person can newly input the cipher from the first digit when the input of the cipher is erroneous ( Step S1). In this example, the hall call button is kept turned off for 10 seconds or more (step S2), and then the first digit of the code can be entered (step S3).

When the hall call button is continuously turned off for 10 seconds or more and the code entry waiting state is entered (step S3), the state where the next hall call button is turned on is awaited (step S4).
Step S5). When the hall call button is turned on, the cryptographic analysis starts (step S6).

A timer is provided so that a new key can be entered from the first digit of the cipher when the cipher input is interrupted, and there is a process for returning to the initial state when a series of cipher input operations are not completed within a certain time ( Steps S7 and S8).

When the button is changed from on to off (step 9), it is determined whether the button is long-pressed or short-pressed by the method described with reference to 2a and 2b in FIG. 2 (step S).
12, step S13, step 14).

After the long press is judged to be the short press, it is judged whether or not the input is made in the order stored as shown in FIG. 3 (step S15). If the order is correct, the designated number of digits is inputted. It is determined whether or not (step 17). If it is incorrect in the sequence check, it is returned to the initial state (step 16).
When the number of digits stored in the address a of FIG. 3 is entered correctly, the cipher match flag indicating that the cipher input was correctly entered is turned on, and then the initial state is restored to end the series of processes (step S18). , Step 19).

In the present process flow, the time for which the button is continuously pressed is provided by providing a counter and the present process is executed at regular intervals. When the button is continuously turned on, the counter is incremented by +1 (step S10, In step S11), when it is turned off, the counter is stopped and it is determined whether the long press or the short press is performed by "counter value at that time x execution cycle (100 ms in this example)" (step S9, step 12, step 1).
3) It adopts the light method. Although the flag is set when the codes match in step S18 of FIG. 4, the outline of the process for registering the hall call depending on the state of this flag is shown in FIG.

In FIG. 5, it is determined whether or not the ciphers coincide with each other by checking the cipher coincidence flag in FIG. 5 (step S1). When the flag is on (the ciphers coincide with each other), it is the same as a normal hall call. Register the cipher floor landing call to (step S3) and clear the cipher match flag (step S3)
To do.
