Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] [Technical field] The original F! A relates to a wireless electric lock device using a touch switch.

[Prior art]

Conventionally, only a specific person can unlock the door! 11! As a guard,
The method of inserting a magnetic card or the method of entering a PIN using a tether is time-consuming, but it is a non-contact method that requires you to stand in front of the device and perform some operations, so it is difficult to use other methods. There is a problem in that the lock may be unlocked due to mutual interference with the system or malfunction due to jamming radio waves, and it is easy to be exploited.

[Purpose of the invention]

The present invention has been made in view of the above points, and its purpose is to eliminate the disadvantages of the non-contact method while eliminating the convenience of the conventional wireless method, and to provide a touch switch type and identification device. The purpose of the present invention is to provide an electric lock device with functions.

[Disclosure of the invention]

Therefore, the present invention includes a portable wireless transmitter that transmits a high frequency signal modulated with a specific code, and a structure configured to control an electric lock when the high frequency signal is received and matches the demodulated code. A wire-type electric lock device comprising a receiver and a transmitter is characterized in that the antenna of the receiver is configured with a touch switch made of a metal piece connected to the tip of a shielded wire. The electric lock is unlocked when the owner touches the touch switch with his or her finger.

(Example) Figures 1 and 2 show an example of the device of the present invention. As shown in Figure 2 (a), a portable transmitter A is modulated with a specific code and emits a high frequency signal. It sends out signals,
It is composed of a modulation circuit 1 and a transmission circuit 2, and a transmission antenna 3 is housed in a case. FIG. 5B shows an example of a modulation method, and in this embodiment, a high frequency 13 pulse signal is used. Receiver B is composed of a receiving circuit 5, a demodulating circuit 6, a code discrimination circuit 7, and an electric lock control circuit 8, and when it is determined that the demodulated code matches a preset code, the electric lock is activated. It is designed to be locked or unlocked by controlling C. Receiving antenna 4i
As shown in FIG.
etc. are fixed.

When using the transmitter, as shown in Figure 1, the transmitter owner puts the transmitter A in a pocket of clothing and touches the edge switch 10 with his or her finger, and the human body acts as an antenna. A high frequency signal is transmitted through the human body and is reliably received by receiver B.

The sensitivity of the transmitter A's transmitting bell and the receiver B are set low so that contactless reception is not possible. In addition, as shown in FIG. 3(a), the transmitting antenna 3 may be formed in the shape of a watch band of the wristwatch-type transmitter A, or the transmitting antenna 3 may be formed in the shape of a watch band of the wristwatch-type transmitter A, or
) As shown in K, the reliability of signal transmission can be further improved by forming a chain of necklace-type transmitters A so that the transmitting antenna 3 is in direct contact with the human body of the transmitter holder. .

〔Effect of the invention〕

As mentioned above, the wire type electric lock device according to the present invention has the following features:
By touching the touch-switch-shaped receiving antenna with the transmitter owner's finger, a high-frequency signal modulated with a specific, fixed code is transmitted, so it can be used with a simple touch-switch type and has a code identification function. Has traditional magnetic h
-Compared to the method using a wireless terminal or a mobile phone-, it does not require complicated operations in front of the door, and there is no risk of malfunction due to foreign radio waves as with conventional wireless methods, making it simple and highly reliable. It has the advantage of being able to provide an electric locking device.
