Wireless remote control using reed switch of unmanned security system {RADIO FREQUENCY REMOCON USED LEAD SWITCH IN SECURITY SYSTEM}

The present invention relates to an unmanned security system, and more particularly, to a wireless remote control using a reed switch to start the boundary by transmitting a boundary start setting signal to the guard terminal device wirelessly in the unmanned security system.

In general, unmanned security systems are installed in homes, shopping malls, offices, etc. to notify the control room in case of an emergency, for example, intruders, fire, or gas leaks. It is a system that automatically communicates emergency situations to personnel dispatch and police station. The unmanned security system provides various kinds of sensors such as pressure sensors and heat sensors, and the signals detected by these sensors and various control signals generated by the user to the control room of the security system wherever it is easy to invade the subscriber building. It is provided with a security terminal device for such, such a security terminal device is disclosed in Korean Laid-Open Patent Publication No. 1997-67030. The guard terminal device as described above uses a memory card (IC card or magnetic card) to set or release the guard start.

These guard terminal devices have recently been set to release or release the guard radio wirelessly without moving to the place where the guard terminal device is located using a wireless remote control, there was a problem that can not be set because it can not determine whether the set is correct.

Accordingly, an object of the present invention is to provide a wireless remote control using a reed switch that can prevent the operation of the guard start by setting the guard start using the access magnetic remote control in the security terminal device of the unmanned security system.

Another object of the present invention is to provide a wireless remote control using a reed switch that can extend the life of the battery using an access magnetic remote control in the security terminal device of the unmanned security system.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. And in describing the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a security terminal device according to an embodiment of the present invention.

The A / D converter 10 detects external intrusion from various sensors (pressure sensor, heat sensor, etc.), It receives gas leakage detection and fire detection signal and converts it into digital signal. The wireless remote controller 26 is provided with a boundary start, boundary release, and emergency key to generate key signals for these key signals and transmit them wirelessly. The RF module 22 demodulates the key signal received from the wireless remote controller 26 and applies it to the CPU 12. The key input unit 24 generates key signals for setting various functions (remote control number setting, partial boundary setting, boundary start time setting, customer ID and control room telephone number input), and applies them to the CPU 12. The timer 14 is composed of a real time clock chip, and provides the current time to the CPU 12 by the real time clock. The CPU 12 receives a boundary start, boundary release, and emergency signal input from the RF module 22 to set boundary start and boundary release, and controls to notify the control room of an emergency situation when an emergency signal is input, and the boundary start mode. Detects a plurality of sensor states from the A / D converter 10 to transmit information on chip particle generation, gas leakage, and fire to the control room, and various operation states according to the operation of the key input unit 24. Outputs a voice message control and display control signal to inform the user of the message. The voice output unit 16 generates the current operating state and the alarm state voice signal under the control of the CPU 12 and outputs the voice signal through the speaker 30. The alarm generator 18 generates an alarm signal for notifying an emergency situation under the control of the CPU 12 and outputs the alarm signal through the piezo buzzer 28. The display unit 20 includes a plurality of LEDs for displaying a current operating state and an alarm state message under the control of the CPU 12, and displaying a plurality of sensor operating states. The communication unit 32 interfaces to communicate with the control room under the control of the CPU 12. And a magnet is attached to the front of the housing of the security terminal device.

The battery 40 for supplying power, and the magnetic reed switch 42 for supplying power to the battery 40 is switched on by the magnet attached to the guard terminal when the wireless remote control near the guard terminal device; A code generator 44 which receives power from the magnetic reed switch 42 and generates a code corresponding to the guard start setting signal, and an RF generator which loads the code generated from the code generator 44 in an RF signal and transmits the code. It consists of 46.

3 is a control flowchart for setting a security start according to an embodiment of the present invention.

1 to 3 will be described in detail the operation of the preferred embodiment of the present invention.

When the user accesses the wireless remote control configured as shown in Figure 2 to the security terminal device configured as shown in Figure 1 in order to set the security guard of the unmanned security system, the magnetic reed switch 42 by a magnet attached to the front of the housing of the security terminal device. ) Is switched on. When the magnetic reed switch 42 is switched on, the power of the battery 40 is supplied to the code generator and the RF generator 46 so that the code generator 44 generates a security start setting code to the RF generator 46. Is authorized. At this time, the RF generator 46 receives the guard start setting code and puts it on the RF carrier and transmits it to the guard terminal device through the antenna 48. Then, the RF module 22 of the guard terminal device demodulates the guard start setting code received through the antenna 21 and applies it to the CPU 12. Therefore, the CPU 12 releases the guard start or the current state is the guard start state When the security guard is set or released depending on whether the state is described with reference to the flowchart of FIG.

In step 101, the CPU 12 checks whether the guard start setting code has been received from the wireless remote controller 26 and proceeds to step 102 if the guard start setting code is received. In step 102, the CPU 12 checks whether the current state is set in the guard start mode, and proceeds to step 104 if it is set in the guard start mode. In step 104, the CPU 12 releases the guard start mode. However, if the current state is not set to the guard start mode, the CPU 12 proceeds to step 103 and sets the guard start mode.

As such, when the wireless remote control 26 approaches the security terminal device in the unmanned security system, power is supplied to the wireless remote control 26 to generate a security code setting code to set the security start mode.

As described above, in the present invention, when the user approaches the wireless remote control unit 26 to the security terminal device in the unmanned security system, power is supplied to the wireless remote control to generate a security code setting code so that security guard mode can be set. It is possible to prevent malfunctions when starting the guard, and also has the advantage that the life of the battery can be extended by supplying power from the battery only when the guard start mode is set or released using the access magnetic remote control.
