Abstract

The present invention relates to a security system using an infrared sensor and to a remote control of a security system installed in homes or offices using a mobile phone or a landline phone.

The present invention installs an infrared transmitter (1) with a built-in reed switch (2) in the door and an infrared transmitter (1) with a built-in shock sensor (10) in the window, and when intrusion is detected, the infrared receiver of the security system ( 13) amplifies the infrared signal detected by the alarm sound and the built-in telephone transmitter / receiver 14 to automatically be notified to the pre-set phone number and at the same time voice warning that can deliver a stronger message to intruders It has a function.

Anyone can easily install it because the above invention uses infrared detection method, and it can expect the effect of giving up the invasion itself because the intruder misunderstands that there is a person in the house because it sends a warning message to the intruder directly by voice. .

Description

Security system using infrared ray {A security system using infrared ray}

The present invention relates to a security system using infrared rays. More specifically, it detects when a thief invades your home or office, issues an alarm sound, and automatically alerts you to a preset phone number. It's about making things happen.

Recently, there are various security systems for preventing thieves from entering the home or office.

However, most security systems use radio frequency (RF--Radio Frequency), so it is not possible to install it unless you are an expert and control and manage the alarm by an external service provider when it is interfered or misoperated by other communication devices. As a result, the alarm sounded continuously until an employee of the contractor went to the site to check the system.

In addition, there is a function of warning by voice to warn the intruder, but in this case, the warning is repeatedly recorded by the pre-recorded voice, so if the intruder knows this and blocks the alarm in a short time, the function as a security system is lost. there was.

The present invention has been made in order to solve the above-mentioned problems, and the object of the present invention is to make it easy for anyone to install by detecting an intruder using an infrared transmitter / receiver that does not require wiring.

Another object of the present invention is to provide a remote control by providing a telephone transmission / reception unit inside the central processing unit constituting the security system, as well as to transmit a warning message directly to the user's voice to access the attacker in a panic. It can't be.

Hereinafter, a method system configuration using infrared rays of the present invention will be described in detail with reference to the accompanying drawings.

Looking at the configuration of the infrared transmitter 1 of the present invention installed in the door or window in relation to Figure 3, the reed switch (2) and the infrared IC operated by a magnet attached to the infrared transmitter (1) installed in the door (3) and transistors (4) (5) and infrared diodes (7), which are operated by an impact sensor (10), operational amplifier (8), and transistor (6) for detecting intrusion into a window or the like. It consists of the relay 9.

The central processing unit 11 for processing the signal sensed by the infrared transmitter 1 is largely embedded with a delay circuit unit 12, an infrared receiver unit 13, a power supply unit 18, an alarm sound generator 17, and a voice sensor. The telephone transmission / reception unit 14, the memory processing unit 15, the hook on / off delay circuit unit 16, and a password setting unit 19 which prevents others from making random calls to operate the system.

Looking at the configuration and operation of the present invention described above in detail.

When the power of the system of the present invention is turned on using the power supply unit 18 or the button is pressed while the power is turned on, the delay circuit unit 12 allows the installer to operate the system and to leave the installation place (about 1 minute). In this case, the delay circuit unit 12, which is a timer, discharges the voltage charged in the condenser 20 at the moment of pressing the button while the first system is switched on or switched on, and the output of the delay circuit unit 12 is in an H state. When the inverter 22 passes through, the output of the inverter 22 becomes 0, so that the relays 23 and 24 are in an off state.

After about one minute, when the capacitor is fully charged, the output of the delay circuit section 12 becomes 0, and after passing through the inverter 22, the output becomes H so that the relays 23 and 24 are turned on and finally the relay 23 and 24 are connected in series to enter the intruder monitoring state.

When the intruder opens the door, the reed switch 2 is activated by a magnet attached to the infrared transmitter 1 installed at the door, and the oscillation output is transmitted to the transistors 4 and 5 when the infrared switch 3 is detected. It is amplified and applied to the infrared diode 7 to emit infrared rays.

When the infrared transmitter 1 is installed in a window or the like, when an impact from an intruder is detected by the shock sensor 10, the shock is amplified through the operational amplifier 8, and then the relay 9 is operated by the transistor 6, and the infrared ray is activated. The infrared rays are emitted under the control of the IC 3.

As described above, when an intruder is detected and infrared rays are emitted from the infrared transmitter 1, the infrared signal is transmitted to the infrared receiver 13, and since the infrared signal detected by the infrared receiver 13 is weak, it is separated into two transistors 32 and 33. Amplified and then amplified by a derrington circuit section consisting of transistors 32 and 33 to drive the relays 25, 23 and 24, and a positive voltage is applied to the base through the transistor 34 and the instantaneous relay At the same time as the 26 is turned on, the capacitor 21 is instantaneously charged to operate the hook on / off delay circuit 16 of the memory processor 15.

The hook on / off delay circuit unit 16 hooks on (sets the handset) the telephone transmitter / receiver 14 built in the present system, and activates the stored memory button after about three seconds. The hook-on time is at least 15 seconds and at most 3 minutes.

If an intruder is detected as described above, the alarm sound generating unit 17 causes the warning siren to sound for about 10 seconds and at the same time, the telephone transmitter / receiver 14 operates to give a preset telephone number to the memory processor 15. It will ring, and after you receive a call to alert you to an intrusion, you can press the # button and your three-digit password to hear the situation immediately. Press the 0 button to speak your own voice message. Through the built-in voice sensor, it is possible to warn the intruder directly by remote user's voice.

If you want to intercept again, press # button. After confirmation, press # button and turn off the phone. All the situation at the installation site will be turned off and back to the intruder monitoring state.

When the user enters the installation site, first call the installation site, press the # button and the password, and then press the specific button on the preset license plate (alarm sound release).

The security system of the present invention as described above can be easily installed and used by anyone because it uses an infrared transmitter / receiver. There is an effect such that the warning message can be delivered directly to the user's voice.
