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 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,
There is an electronic lock device that is equipped with a so-called theft alarm system that sounds a theft alarm when there is fraudulent activity, that is, when a push button switch is repeatedly operated. 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 or the door is operated multiple times due to such fraudulent activity, a horn installed on the car body is activated, so even if it is a nuisance act, an alarm will be issued. The ringing 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 not only activates an alarm when the pushbutton switch of an electronic lock is pressed repeatedly, but also provides an audible warning that the alarm will sound if the pushbutton switch of an electronic lock is repeatedly pressed. The purpose is to warn before IIS.

Function: When multiple push button switches are operated repeatedly, the first counting circuit counts the number of repeated operations, and when this count matches the set value of the first counting circuit, an audible alarm sounds. A half-warning is given, and when the next push button is pressed, the alarm will be activated and an alarm will sound since it will match the set value of the second counting circuit.

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

In the figure, FIG. 1 is a block diagram of an electrical control system that generates a warning sound whenever the alarm is activated.

1 is a speaker, 2 is an amplifier circuit, and a control station module 6 for manual input of a password is provided, which is provided with a plurality of push button switches 3, and a ^10 converter 7 is connected to this control station module 6. A microcomputer 8 having a CPU having an arithmetic processing function, and storage elements such as a write RAM and a read ROM is connected to the D/D converter 7.

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 the microcomputer 8, and an AN
Together with the D circuit 13, a sound generating element 11 that gives a sound warning that an alarm will sound, an amplifier circuit 2, and a speaker 1 are connected to the alarm device 10.

Further, a timer 15 connected to the microcomputer 8 has 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 circuit 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 pressed.

Effects of the Invention The present invention provides a first counting circuit and a sound generating element in the first counting circuit, so that when the alarm is activated, it is possible to give a voice warning to stop unauthorized operation. This has the effect of not only preventing battery loss but also preventing battery loss.
