Description

Description: TECHNICAL FIELD The present invention relates to a cryptographic call registration type elevator control device in which only a specific user can register a call on a specific floor of an elevator.

[Prior Art] Generally, an ordinary elevator can be freely used by an unspecified number of people. However, specific floors such as the office floor of the office building, the computer room floor, the store at the bottom and the residence at the top, the so-called Getabaki building's residence floor, are
It should only be available to specific people for crime prevention and privacy protection.

As the most typical means for this purpose, there is a method in which a call button on a specific floor is configured by a key switch and the key switch is turned on by a key to register the call. However, this method requires that the key be carried, which is troublesome, and if the key is forgotten, the elevator cannot be used.

Therefore, in the prior art, as disclosed in JP-A-55-66468 and JP-A-57-98474, the push buttons provided in the elevator car or the hall are arranged in a predetermined order. Only when a cryptographic code is input by operating in a special mode such as pushing, a car call or hall call on a specific floor can be registered.

In the prior art, the cryptographic call registration device is configured by a relay circuit, but in recent years, it is configured by a program of a microcomputer. In addition, if the elevator is always registered as a cryptographic call, passengers other than a specific person, for example, passengers having a business on the specific floor or a newspaper delivery person can not use the elevator, so a 24-hour timer or The changeover switch can switch between normal call registration and encrypted call registration.

[Problems to be Solved by the Invention] In the above-mentioned conventional encryption type call registration device for an elevator,
It was difficult to determine whether the floor where the call was to be registered could be used for normal call registration or was encrypted.

So, in recent years, first of all, if you press the call button and the call response lamp lights up, call registration is completed by the normal method,
If the call response button does not light up, it is determined that the call is encrypted and the encryption code is input.

However, in this method, even if the call button is pressed, the call is not accepted due to poor pressing,
If you forget the floor you pressed, you will not be able to determine whether it is the secret floor or not. Also, it is necessary to enter the encryption code within a predetermined time, but it is impossible to determine whether or not the predetermined time has been exceeded, so there is a problem that calls other than the call button pressed with the intention of the encryption code will be registered. there were.

For example, this problem also applies to the technique disclosed in JP-A-53-49749. The technique disclosed in JP-A-53-49749 discloses that when a push button is operated in a manner different from usual,
It is designed to move up and down to a specific floor, which is different from normal. However, if the encryption code is mistakenly input for another specific floor, an unintended call for another specific floor is registered. In addition, if the number of digits of the encryption code is wrong and one digit is input more, the call of the last digit is wrongly registered.

Therefore, the present invention has been made to solve the above-mentioned problem, and it is possible to easily determine the call registration of a specific floor that is an encryption code and the inputtable time of the encryption code,
It is an object of the present invention to obtain an elevator control device that does not respond to a cryptographic code due to the erroneous operation even if the erroneous operation of the cryptographic code is input during that time.

[Means for Solving the Problems] An elevator control device according to the present invention determines that a call button on a specific floor of an encryption code to be pressed in a predetermined pattern has been pressed, and causes the call response lamp to blink. ,
A blinking counting means for starting counting of a predetermined time period, and a call registration means for registering a call on a specific floor and turning on a call response lamp when the input of the encryption code is completed within a predetermined time period of the blinking counting means, It is provided with blinking stopping means for stopping the blinking of the call response lamp of the call registration means by the blinking counting means when the input of the encryption code is completed or a predetermined time period ends.

[Operation] In the present invention, when the blinking counting means determines that the call button on the specific floor has been pressed, the call response lamp on the specific floor blinks to indicate that the encryption code is waiting to be input. Then, when the input of the encryption code is completed or when a predetermined predetermined time period elapses, the blinking is stopped and the fact that the normal call registration mode is restored is displayed. The blinking of the response lamp makes it easy to determine that the call button on the specific floor has been pressed and it is time to enter the encryption code.

[Embodiment] An embodiment of the elevator control apparatus of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an elevator control device of the present invention, FIG. 2 is a front view of a car operation panel in an embodiment of the elevator control device of the present invention, and FIG. 3 is a view of an elevator control device of the present invention. RAM in the control circuit in the embodiment
FIG. 4 is an explanatory view showing addresses and contents of FIG. 4, and FIG. 4 is a flowchart showing a procedure of encryption processing in the embodiment of the elevator control device of the present invention.

In the figure, 1 is a control unit in a control panel installed in a machine room, and 2 is a car operation panel. The control unit 1 is composed of a microcomputer, and is a central processing unit (hereinafter abbreviated as CPU) 11 that performs overall control and data processing.
From the ROM 12 that stores the elevator operation control program and the encryption call registration processing program, the RAM 13 that stores the data such as the calculation result in the CPU 11, the door open / close button and the destination button of the car operation panel 2. Receiver 14 for taking in the signal of the, and driver 15 for outputting the processing result in the CPU 11 to the car call response lamp etc. of the car operation panel 2.
And ROM12, RAM13, receiver 14 and driver
Reference numeral 15 is connected to the CPU 11 via the internal bus 16.

The car operation panel 2 has a door open button 21, a door close button 22, and destination buttons 31a, 32a, 33a, 34a, 35a on the first to fifth floors, and the button signals of these buttons are the receivers of the control unit 1. It is supposed to be received by 14. Also, the basket control panel 2
Are the car call response lamps 31b, 32b, 33b, 34b, on the 1st to 5th floors.
35b, these lamps are connected to the driver 15 of the control unit 1.

Next, the operation of this embodiment configured as described above will be described with reference to FIGS. 3 and 4.

FIG. 3 shows the address and the contents of the cryptographic determination area stored in the RAM 13. FIG. 4 is a flowchart showing the procedure of the encryption processing program, which is ROM1.
Stored in 2.

In this embodiment, normal car call registration is possible on the 1st to 4th floors, and only the 5th floor is an encryption type in which "first press the button on the first floor and then the button on the second floor". , The code of the button is "01" for the button on the first floor, "02" for the button on the second floor, etc., and the numeric value for that floor is expressed in hexadecimal notation. The door open button is "F0" and the door close button is "F1". ”. Therefore, in this example, the data at addresses 8010, 8020, 8030, 8040 are all "00", and the data at addresses 8050-8053 are "F".
"F", "01", "02", "FF".

First, a normal car call registration operation will be described by taking the first floor as an example.

When the destination button 31a on the first floor of the car operation panel 2 is pushed, the button signal is taken into the CPU 11 through the receiver. Accordingly, in step 51 of FIG. 4, it is determined whether the call button has been pressed. Since the result of this determination is "YES", the routine proceeds to step 52, where it is determined whether the call button is on the specific floor. That is, in step 52, because it is the call button on the first floor,
Initialize the address X of RAM13 = 8010 and read the data of address X. Since this data is "00" as is apparent from FIG. 3, the determination in step 52 is "NO".
Then, after shifting to step 61 and performing normal call registration, counting of a predetermined time period is stopped in step 59, the initial value (normally 5 seconds) is set, and normal call registration processing is completed.

Next, the operation of call registration using the encryption code will be described.

When the destination button 35a on the fifth floor is pressed, it is determined in step 51 that the call button has been pressed, and the process proceeds to step 52. At step 52, since the call button is on the fifth floor, the address X = 8050 of the RAM 13 is initialized and the data at the address X = 8050 is read. Since the car call determination flag data on the fifth floor at this time is "FF", step 52 determines that the button is a call button on a specific floor, the process proceeds to step 53, and counting of a predetermined time period is started, and the driver A blinking command is output to the call response lamp on the specific floor, that is, the call response lamp 35a on the fifth floor through 15 to blink the response lamp 35a. Then, in the next step 54, it is determined whether or not the predetermined time period has ended. If the determination result is "NO", the flow proceeds to step 55 and it is determined whether the next button has been pressed. If it is detected that the next button is pressed, the address of RAM13 is set to X ← (X + 1) = 8051 and the next step
Continue to 56.

If the button on the first floor is pressed, the button data is "01" and the data at address X = 8051 is "0".
Since it coincides with "1", the button of the personal identification code in step 56 becomes "YES" and the process proceeds to step 57. In step 57,
The data at the address (X + 1) = 8052 is read and it is determined whether the encryption code input is completed. At this time, as is clear from FIG. 3, the data read from (X + 1) = 8052 is “02”, so that step 57 judges “No” and returns to step 54. In step 54, if it is within the predetermined time, similarly proceed to step 55, and if it is assumed that the button on the second floor is subsequently pressed, set X ← (X + 1) = 8052, proceed to step 56, and press the button. Since the data “02” of “1” and the data “02” of the address 8052 match, the process proceeds to step 57. At step 57, since the data of the address (X + 1) = 8053 is “FF”, it is judged that the input of the encryption code is “YES”, and the process proceeds to step 58. In step 58, the car call on the 5th floor is registered, the call response lamp is lit up to display the completion of the input of the personal identification code, and in step 59, the counting of the predetermined time period is stopped, the initial value is set, and the process ends. Become.

If the input is not completed within the specified time, step
At 54, the end of the predetermined time period becomes "YES", at step 60, the call response lamp on the fifth floor is turned off, and at step 59, the predetermined time period is set to the initial value. If you press the wrong button (here, the third floor) instead of the second floor after pressing the button on the first floor, the button data will be "03" at step 56 and the data "02" at address 8052 will be displayed. Since it does not coincide with the above, it is judged that the button is not the personal identification code, and the processing is the same as the case of ending the predetermined time period.

Therefore, in the above-mentioned embodiment, when the destination button on the secret floor is pressed, the call response lamp blinks for a predetermined time. The determination can be made, and it can be surely determined whether or not it is the secret code floor and whether or not the button is pressed during the input possible time.

Thus, the elevator control device of the present embodiment, the destination code 1a ~ 35a, the car call response button 31b ~ 35b and the like push the push button provided in the car or at the hall in a predetermined pattern to operate the encryption code. When an input is made, in the elevator control device that enables registration of the call of the specific floor, it is determined that the call button of the specific floor of the encryption code to be pressed in the predetermined pattern is pressed, and the call response lamp blinks. Step 52 to start counting for a predetermined time period
And step 54 to step 58 of registering a call of a specific floor and turning on a call response lamp when the input of the encryption code is completed within a predetermined time period of the flashing counter means When the call registration means and the input of the encryption code or the predetermined time period ends,
The flashing counting means is provided with a flashing stopping means consisting of step 54 or step 56 and step 60 for stopping the blinking of the call response lamp of the call registration means.

In the above embodiment, the specific floor is the 5th floor, and the encryption code is "first press the first floor button, then the second floor button".
I decided to use the doorstep button and the door close button,
You may increase the number of times the button is pressed.

Further, in the above embodiment, the response lamp is made to blink when the call button on the specific floor is pressed, but in consideration of the case where it may induce mischief, the response lamp is made to blink or turned off with a switch or the like. It may be possible to switch whether to leave it as it is.

[Effects of the Invention] As described above, according to the elevator control device of the present invention, when the blinking counting means determines that the call button on the specific floor is pressed, the call response lamp on the specific floor blinks to perform encryption. When the input of the code is completed, or when the input of the encryption code is completed or a predetermined time period has elapsed, the blinking is stopped and the normal call registration mode is restored. The blinking of the response lamp makes it easy to determine that the call button on the specific floor has been pressed and it is time to enter the encryption code. When the call button on the encrypted floor is pressed, the call response lamp blinks for a predetermined time, so it is easy to determine whether the button on the specific floor has been pressed and the available time for entering the encryption code. effective.
