Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an alarm generation control device for an electronic lock device that generates an alarm when a push button of an electronic lock provided on an automobile door is repeatedly pressed in an unauthorized manner. It is something.

Conventional Technology Modern electronic locking devices for automobiles lock and unlock the door by pressing a door handle or multiple push buttons near the door handle in accordance with a password. It has become.

In addition, in such an electronic lock device, the push button switch provided on the electronic lock is exposed outside the vehicle interior, so it is easy for this push button to be operated accidentally for the purpose of tampering or theft. In order to prevent fraudulent acts,
The so-called theft fiff is designed to sound a theft alarm when there is fraudulent activity, that is, when a push button switch is repeatedly operated.
There is an electronic lock device equipped with a security system. For example, JP-A-56-105076, which has already been published as a publication.
and Utility Model Publication No. 59-17558.

Problems to be Solved by the Invention Unlike cylinder locks, the push button of an electronic lock device does not require a key, so it is easy to operate in the event of tampering or theft, and therefore there are many cases of fraudulent activity. When the door is opened due to such fraudulent activity, or when the door is operated repeatedly several times, a horn installed on the car body is activated, so even if it is a nuisance act, the door will be alerted. A beeping sound can sometimes be mistaken for theft. Moreover, it has the disadvantage that it consumes a lot of battery power when the alarm is activated.

Means for Solving the Problems The means in the present invention is such that when a push button switch of an electronic lock is pressed repeatedly, before the alarm is activated, it is possible to prevent the alarm from sounding in advance. The purpose is to display the text in the form of letters, and to display the letters on a warning issuance display window formed on, for example, a door panel, a door handle, or an escutcheon provided with a door handle.

Function: When a plurality of pushbutton switches are repeatedly operated, the first counting circuit counts the number of times the push button switches are repeatedly operated, and when this count matches the set value of the first counting circuit, an alarm is issued, for example, on a door panel. For example, a display with the words "Next time the alarm will dim" lights up or dims on the display window, and the next time the pushbutton switch is operated, it will match the set value of the second counting circuit, so the alarm will be activated. will be activated and sound an alarm.

Example An embodiment of the present invention will be described below with reference to the drawings.

In the figure, FIG. 1 shows an electrical block diagram for displaying an alarm issuance in letters on the alarm issuance display window 2. In FIG.

In FIG. 1, a control station module 6 for manually inputting a personal identification number is provided with a plurality of push button switches 3, and a ^/D converter 7 is connected to this control station module 6. CP with arithmetic processing function
The write RA) 14 is connected to the microcomputer 8 having a storage element such as a read ROM.

Further, a first counting circuit 9 for counting the number of operations of the push button switch 3 is connected to the timer 14 connected to this microcomputer 8, and a first counting circuit 9 is connected to the first counting circuit 9.
Along with the ND circuit 13, a character display element 11 is connected to display characters on the alarm issue display window 2 on a liquid crystal when the alarm 10 sounds. This character display element 11 is lit or blinks.

Further, a timer 15 connected to the microcomputer 8 includes a second counting circuit that counts the number of times when the push button switch 3 is operated next time after the first counting circuit 9 reaches the set value. Connect 16.

This second counting circuit 16 is connected to the alarm 10 together with an AND circuit 17 and an alarm control circuit 18, and the output of this second counting circuit 16 is determined when the output of the first counting circuit 9 is completed by the timer 14 and the next An output signal is applied to the alarm device 10 only when the push button switch 3 is operated to suppress.

Effects of the Invention In the present invention, an alarm is activated by connecting a first counting circuit to an alarm control circuit in which a character display element is connected to the first counting circuit and an alarm is connected to the second counting circuit. Furthermore, since the user is notified by text that the alarm will sound in advance, it is possible to interrupt the continuation of fraudulent activities such as bullying and theft. Furthermore, it is possible to obtain effects such as preventing battery loss.
