Abstract

PURPOSE: A security alarm control method is provided to control ON/OFF of an electric light by using a remote controller and operate the electric light and an alarm device when an intruder is sensed through a body sensor. CONSTITUTION: An infrared signal is received from a remote controller. It is checked whether the infrared signal commands to set a security mode. If the infrared signal commands to set a security mode, it is judged whether the security mode is a leaving-home security mode or a sleep security mode. In the case of the sleep security mode, when an intruder is sensed, brightness of indoors is judged, and if the brightness is below a pre-set intensity of illumination, an alarm signal is generated by controlling an electric light and an alarm device. In case of the leaving-home security mode, when an intruder is sensed, brightness of indoors is judged, and if the brightness is below a pre-set intensity of illumination, an alarm light is turned on by controlling the electric light. It is judged whether a security release command is inputted from a remote controller, and if no release command is inputted, it is judged whether scores of seconds elapses. If the security release command is not inputted in the lapse of scores of seconds, an alarm sound is generated.

Characterized in that the steps occur as follows. With reference to the present invention will be described in more detail.

1 is a circuit diagram showing a security intrusion alarm control device for security according to the present invention, Figures 2a and 2b is a flow chart illustrating a security alarm control method.

The illuminance sensor (CdS) is configured to detect the illuminance by changing the resistance value according to the irradiation amount of light according to the room brightness, the human body sensor (SEN) to have an infrared ray emitted from the human body to output an intrusion detection signal. Is configured, the amplification and noise filter unit 60 is configured to amplify the signal output from the human body sensor (SEN) and filter the noise, the remote control receiver 90 is a load control transmitted from a remote control (not shown) And receiving an infrared signal corresponding to a crime prevention setting command, converting the signal into an appropriate signal, and outputting the load signal. The load driving units 50a to 50c are connected to an input signal of a human body sensor SEN or a remote control receiver 90. It is composed of switching elements Q1 to Q3 and relays REL1 to REL3 operated by receiving a predetermined predetermined control signal, and the alarm loads 70a, 70b, and 80 are each load driver 50a. In accordance with the drive signal of ~ 50c) is provided with an AC power to the lamp (70a, 70b) and the alarm buzzer 80 to light the alarm light or generate an alarm sound.

On the other hand, the human body sensor (SEN) is preferably composed of an infrared sensor for detecting the infrared rays emitted from the human body, the illuminance sensor (CdS) when the illuminance (brightness) of the room is less than about 15 to 30 Lux (Lux) The first load 70a and the second load 70b, which are electric lights, are operated because the security lamp does not need to be turned on when the room is bright. To about 300 lux)

The amplification and noise filter unit 60 is a non-inverting terminal for RC filters for removing noise by receiving an intrusion detection signal through the human body sensor SEN, a signal output through the RC filter, and a predetermined reference signal, respectively. A first low-pass amplifier (OP1) for amplifying by passing only the low-pass signal of the signal supplied to the (+) and the inverting terminal (-) and the non-inverting terminal, and connected to the input terminal of the inverting terminal (-) human body sensor A second low pass amplifier OP2 for amplifying and amplifying only the low pass signal among the signals output from the SEN and outputting the amplified signal to the inverting terminal of the first low pass amplifier OP1 is provided.

Each load driver 50a to 50c and the loads 70a, 70b, and 80 have the same or similar configuration, and the first load driver 50a includes a bridge circuit unit 10 in which an input AC power source (AC power source) is rectified. The relay REL1 and the switching element Q1 are connected in series between the output terminal of the output terminal and the ground voltage, and the power is supplied to the relay REL1 as the switching element Q1 is turned on by the control signal of the microcomputer 1. The switch is contacted, and the AC power is supplied to the load 70a connected to one end of the relay switch through the contacted relay switch, thereby operating the load 70a.

In addition, when the intrusion detection signal is input through the human body sensor SEN, the microcomputer 1 determines the brightness of the room through the illumination sensor CdS, and the load driver 50a to 50c when the brightness is less than the preset illuminance. It is configured to operate the alarm loads (70a, 70b, 80) by controlling the control signal by determining the signal input from the remote control receiving unit 90 and to control the operation of the alarm load.

In addition, reference numeral 100 denotes an operation selection unit that is arbitrarily selected by a user, and includes a plurality of switches SW1 to SW4. The first switch SW1 turns on / off the first load 70a and the second switch SW2. ) Turns on / off the second load 70b, and the third switch SW3 is configured to determine whether to enable or disable the signal input to the remote controller receiver according to on / off and the fourth switch SW4. Is configured to determine whether to operate the security function according to the on / off.

That is, when there are two security control devices indoors, a single remote control can operate a plurality of security control devices separately. When the third switch (SW3) is off, the corresponding security control device ignores the command operated by the remote control. do. When the fourth switch SW4 is on, the load is switched to a security mode that operates first according to the detection signal of the human body sensor SEN, and when it is off, the load is switched to a remote control priority operation mode.

1, when the AC power is received from the outside and stored through the bridge circuit unit 10 and the rectifier circuit 20, the power is input to the microcomputer 1 in the stabilized state through the reset unit 30. Consists of input parts 10 ~ 40, variable resistors VR1 and VR2, and capacitors C1 and C2 to adjust the time or illuminance. The variable resistor VR1 operates only when it is dark in the state where the security function is released. The control unit 110 and the oscillation unit 130, such as an operation sound generator (BP: beeper) for outputting the operation sound when the mode change or command input and a crystal oscillator for oscillating the reference clock signal is used. Equipped.

Referring to the operation process of the crime prevention intrusion alarm control device configured as described above with reference to Figures 2a and 2b, the signal of the human body sensor (SEN) is amplified and filtered through the amplification and noise filter unit 60 and the microcomputer (1) Is entered.

In the microcomputer 1, if the pulse width of the input signal is equal to or less than a predetermined size (for example, 50 ms), it is regarded as noise and is ignored.

Voltage and Lux control voltage input through the illuminance sensor CdS whose resistance value changes according to the irradiation amount of light while a normal signal is input to the microcomputer 1, that is, the variable resistor VR2 and the capacitor of the controller 110. When the voltage input through the C2 is compared and analyzed by the microcomputer 1 and the voltage of the illumination sensor CdS is high (when the illuminance of the room around the sensor is smaller than the lux set by the variable resistor VR2), the microcomputer ( 1) controls the switching elements Q1, Q2, and Q3 of the load driving units 50a, 50b, and 50c to contact the relay switches REL1, REL2, and REL3, thereby providing a plurality of loads 70a, 70b, which are electric lights. The load 80, which is an alarm, receives AC power through each of the relay switches REL1, REL2, and REL3 to light the alarm lights 70a and 70b or generate an alarm sound 80.

Once a normal signal is input through the human body sensor (SEN) after the load is activated, the plurality of loads (70a, 70b, 80) are continuously operated for a set time regardless of the indoor illuminance, which is the main surface of the illuminance sensor (CdS). Let's do it.

On the other hand, once a certain time has elapsed while the loads 70a, 70b, and 80 are operated, they remain off even if a normal signal is input through the human body sensor SEN within a predetermined time (for example, 1000 ms). In addition, after a certain time elapses, each load 70a, 70b, and 80 may be reactivated only when a normal signal is input through the human body sensor SEN.

In addition, if the input signal level of the human body sensor (SEN) is not detected, it maintains a constant voltage (for example, 2.5V), and if it detects more than a certain voltage (3.2V) or less than a certain voltage (1.8V) It is regarded as normal signal level, and the signal level between them is regarded as noise and ignored.

As described above, the signal of the human body sensor (SEN) is processed and the next remote control receiving function processing method will be described. The remote control command unit 90 may transmit a remote control command regarding on / off, sleep and crime prevention of a load transmitted from a remote controller (not shown). ), The microcomputer 1 analyzes the remote control reception data to control the switching elements Q1 and Q2 of the load driving units 50a and 50b to the loads 70a and 70b, which are lamps, to relay REL1 and REL2. Turn on and turn on or turn off.

When the loads 70a and 70b are turned on by the remote controller, if the loads 70a and 70b are kept lit and turned off by the remote controller, they are not subject to the indoor illuminance and lighting time around the illumination sensor. In response to the input of the sensor SEN, the loads 70a and 70b of the lamp are turned on or off according to the indoor illuminance around the illumination sensor CdS and a set time. Of course, the load 80, which is an alarm, generates an alarm sound for a set time when the human body sensor SEN is detected without being affected by the illuminance sensor CdS.

The sleep function operates only when the loads 70a and 70b are on, and when the user presses the sleep button on the remote control in the off state, the microcomputer 1 generates an abnormal sound through the operation sound generator BP (for example, twice every 0.1 seconds). )

When the loads 70a and 70b are turned on, the off time is determined according to the number of pushes of the sleep button. For example, when the sleep button provided on the remote controller is pressed once, the microcomputer 1 recognizes this and then 30 minutes. After turn off the load (70a, 70b) and press the sleep button once more within 30 minutes to turn off after 60 minutes, press the sleep button once more within 60 minutes to turn off after 90 minutes.

If you press the sleep button once more (30 times in total) within 30 minutes, the sleep function is released.If the sleep function is in operation, the sleep function is turned off or the sleep function is turned off. do.

The crime prevention function is that when crime prevention is set, the loads 70a and 70b are turned off and the human body sensor SEN is activated.

When the room around the ambient light sensor becomes bright and dark, the loads 70a and 70b turn on and off for a certain time (for example, 5 hours) as it was at the time of crime prevention.

When it is dark again, the above function is repeated, and it is determined that the brightness change is effective only if it lasts for a predetermined time (for example, 1 minute).

If the darkening within a certain time after the initial security setting the load (70a, 70b) in the state at the time of the security setting, the human body sensor (SEN) operates.

In this state, if a person is detected within a certain time (for example, 20 seconds) and then a person is detected by the human body sensor (SEN), the operation sound for a certain time (for example, every 20 seconds for 1 second) regardless of the illuminance If the preliminary warning is issued by outputting to the generator BP and the security function is not released within a predetermined time (for example, 20 seconds), the microcomputer 1 lights up the lights 70a, 70b, the alarm 80, and the light emission as it is at the time of setting. Power supply is controlled by diode (LED1, LED2) to output alarm signal.

It sets the security function in the room just before going out, and when the owner goes out, it is detected by the human body sensor (SEN) and when the owner or the intruder enters again when the house is empty, the operation sound is detected by the human body sensor (SEN). If warning is made by generator (BP) and security function is not released even after a certain period of time (invaders are impossible to release), not only operation sound generator (BP) but also lights 70a and 70b, alarm 80 and light emitting diode In case of output through (LED1, LED2).

This also applies to the case of setting the security function with the remote control indoors without going out when going to bed.In this case, no person is detected by the human body sensor (SEN) within a certain time (for example, 20 seconds) after the security setting. In this case, when a person is subsequently detected, the microcomputer 1 immediately outputs a continuous sound through the operation sound generator BP, and at the same time, the lights 70a and 70b, the alarm 80 and the light emitting diode LED1 are set as they are. , LED2) is controlled to output alarm signal.

In this way, the security alarm control device needs to be classified into an out-of-home security mode and a sleep-proof security mode, because there is a risk of operating the alarm signal without time to release the security mode when the homeowner returns home. That is, when going out, the main warning is given after several seconds after the preliminary warning first, and when not going out, the main warning is given immediately so that the security function can be more faithfully performed.

As described above, the control method of the intrusion alarm apparatus of the present invention is a sleep function processing method in which the off time is determined according to the number of pushes of the sleep button when the loads 70a and 70b are turned on, and crime prevention is set. When the loads 70a and 70b are turned off and the human body sensor SEN is activated to detect the person within a certain time and then the person is detected again, a preliminary alarm is made through the operation sound generator BP. Security function processing method for controlling the load (70a, 70b), alarm 80 and the light emitting diodes (LED1, LED2) to operate if not released and the pulse width of the input signal through the human body sensor (SEN) is a normal signal If acceptable, compare the voltage of illuminance sensor (CdS) with the voltage for lux adjustment, and if the voltage of illuminance sensor (CdS) is large, turn on the loads (70a, 70b) and turn on / off and sleep Receive remote control data When the loads 70a and 70b are turned on through the mocon, the indoor illuminance and setting time around the illuminance sensor are not applied, and when the load is turned off through the remote control, the illuminance and setting near the illuminance sensor are received by the pressure of the human body sensor SEN. The load 70a and 70b are largely composed of a remote control receiving function processing method of turning on / off with time.

As described above, by designing a human body sensor and a remote control receiver in the light switch provided in each room of the home, the lamp can be used as an alarm device for security, and the remote controller can set the sleep function and on / off of the lamp arbitrarily. It is possible to provide a multifunctional security sensor such as can be controlled.

Therefore, in the present invention, after the human body sensor and the remote control receiver in the indoor light switch in the remote control on and off the light using the remote control and when setting the security mode with the remote control when the intruder is detected by the human body sensor By activating the overwintering, you can use the lamp as a lighting for everyday use, and use the lamp as a security alarm signal when you go to bed or go out, and operate the light and the alarm differently when you go to bed and go out. There is an advantage that can operate the alarm device in the optimal state depending on the situation.
