The present invention relates to an alarm system installed in a car or a restricted area, and more particularly, the user can arbitrarily control the sensitivity of a detection sensor set to detect an external signal to suit the surrounding situation. The present invention provides a novel alarm system remote control apparatus and its control method which can contribute to cost reduction by simplifying the circuit.

In general, a separate alarm system is installed in a place or a car that needs to restrict outsiders.

The alarm system is provided with a sensing means such as an impact sensor, an ultrasonic sensor, an infrared sensor for sensing an external situation, and an alarm device that operates according to a sensing signal of the sensing means.

However, in an alarm system, the detection means that are designed to detect external signals are often very large when initially set to react very sensitively or vice versa.

For example, a car uses a shock sensor that detects a shock so that a vehicle owner can respond quickly by generating a warning sound when a certain contact is applied to the vehicle due to theft of the vehicle.

The shock sensor is initially fixed to the vehicle in a preset form to operate within a certain allowable range, so the relatively sensitive detector sounds an alarm even without harming the vehicle, causing damage to nearby people. In particular, when the alarm sounds at night there is a problem that the noise damage range is greatly expanded.

As such, it is conventionally used only in the form of the initial setting, so that the user cannot arbitrarily change the sensitivity of the detector according to the surrounding environment, and in order to change the setting environment, the user must reset the method by directly operating the detector. It is pointed out that work is cumbersome and inconvenient.

In addition, handheld devices (wireless remote controls) that are designed to remotely control them in conjunction with vehicle remote controls and anti-theft devices have the advantage of ease of use, while retaining only simple switching (ON / OFF) functions to operate the system at close range. Doing.

The conventional problem as described above was caused by the user's arbitrary setting of the sensitivity of the sensor to suit the surrounding situation, and the sensitivity setting operation was performed by a user's direct operation.

Accordingly, the present invention has the object to solve the conventional problems as described above, the technical problem to be solved by the present invention is to provide a portable remote control such as a remote control or anti-theft device for starting the vehicle provided for the user's convenience and The purpose of the present invention is to provide an alarm system remote control device that can reduce the noise damage caused by frequent operation of the detector by resetting the sensitivity of the preset sensor to the surrounding environment using the same portable device.

In addition, the alarm system remote control device of the present invention has another object to contribute to cost reduction by simplifying the circuit.

In order to achieve the above object, the present invention compares / determines a remote control capable of remote control, a sensing unit having a plurality of sensing means for sensing an external input signal, and an external signal input to the sensing unit. An alarm system comprising a control unit connected to a portable device and a signal transmitter / receiver capable of transmitting / receiving to control an impact sensor and an alarm means operated by a signal of the shock sensor, wherein the portable device controls an impact sensor. A sensitivity setting device for outputting a specific signal (code) is installed, and a shock sensor module is installed between the shock sensor and the controller to control the sensitivity of the shock sensor so that the user can arbitrarily select the sensitivity of the shock sensor using a portable device. Provided is an alarm system remote control, characterized in that configured to enable control and setting.

In another aspect, the present invention is to determine the sensitivity delay time of the shock sensor to the length of the same wavelength as the vibration signal amplified by the amplifier of the shock sensor module, the delay time is set within 0 ~ 3 seconds alarm system control method To provide.

Hereinafter, an alarm system remote control apparatus according to the present invention will be described in detail with reference to the accompanying example drawings.

1 is a block diagram showing a schematic configuration of an alarm system remote control device to which the present invention is applied, FIG. 2 is an exemplary view showing a portable device for remotely controlling an alarm system, and FIG. 3 is a remote control of an alarm system to which the present invention is applied. The circuit configuration of the device is shown.

As shown therein, the portable device is provided with a switching means (11: on / off) for remotely controlling the system mode by an independent power source (AAA type Vattery) and a display device 14 capable of showing the setting contents through the screen. (10: remote control), a sensing unit 24 having a plurality of sensing means for sensing an external input signal, shock sensor 25 for comparing / judging the external signal input to the sensing unit 24, the Alarm system including a control unit 23 is connected to the portable device 10 and the signal transmitter / receiver 22 capable of transmitting and receiving to control the alarm means operated by the signal of the impact sensor 25, etc. (20) is configured to detect the vehicle state changes (shocks, doors, engines, trunks, hoods, etc.) according to external intrusion or accidental situation is configured in the same manner as in the prior art.

The remote control device of the alarm system of the present invention additionally installs a sensitivity setting device 70 for outputting a specific signal (code) to the portable device 10 to control the shock sensor 25, and provides a shock sensor ( The shock sensor module 80 for setting the sensitivity of the 25 is installed so as to be connected between the impact sensor 25 and the control unit 23 and the shock sensor using the sensitivity setting device 70 attached to the portable device 10. It is characterized in that the user is configured to remotely control the sensitivity of the predetermined shock sensor 25 while controlling the module 80.

The sensitivity setting device 70 embedded in the portable device 10 is electrically connected to a plurality of setting buttons 72: 72a, 72b, 72c to output a specific signal and uses the setting buttons 72. Thus, the sensitivity level of the detector is arbitrarily increased / decreased, and the operation and setting contents of the setting button 72 are displayed on the display device 14 as a specific icon or figure.

The shock sensor module 80 to control the shock sensor 25 is an amplifier 82 (OP AMP) for amplifying a minute electric signal input from the shock sensor 25 of the alarm system, the amplified signal of the amplifier 82 Rectifier 84 is provided with a rectifying circuit for converting, and a comparator 86 for comparing / determining the input signal of the rectifier 84 with a reference voltage and transmitting it to the control unit 23.

As shown in FIG. 3, the rectifier 84 includes a rectifier circuit in which two resistors, two capacitors, and a diode are electrically connected to each other so that the rectifier 84 is input to the amplifier 82 to amplify an electric signal. To convert it into a circuit.

The detection signal input to the impact sensor 25 generates a longer wavelength, such as a tremor signal, as the impact increases as shown in FIG. 4. Therefore, if the amplifier 82 amplifies the electric signal input to the shock sensor 25, that is, the magnitude (strong, weak) of the shock largely, it is possible to calculate the delay time, so if it is transmitted to the actual comparator 86 The comparator variously controls the sensitivity of the shock sensor by using the delay time. The delay time at this time is preferably within 0 to 3 seconds.

As shown in FIG. 4, when a specific setting mode is input from the portable device 10 in the standby state, the controller 23 is configured to control the system to detect an external state change in the standby state according to the electric signal. It will switch to alarm system mode.

The electric signal according to the external state change detected by the shock detection unit 24 is compared with a reference value preset by the impact sensor 25 and when the state change signal is input, the reference value is compared and output, and the reference value is less than or equal to the set value. If it is determined to return to the standby state to detect the change of state. When it is determined that the reference value or more is determined, it is determined that the change has occurred externally, and it is determined whether the state change signal is continuously received for a predetermined time.

At this time, the alarm generated when the external intrusion or accidental situation is detected in the alert mode is made of alarms received when a light shock is applied, such as surrounding vibration or pedestrian contact.

The above alarm signal is a shock detection icon displayed on the LCD of the display device, a weak shock signal notified by beep or vibration, and an alarm generated when an external shock that may damage the vehicle is applied. Is displayed and a strong shock signal to inform the user by Beep or vibration, the door icon on the LCD blinks when the door is detected by the key or other tool without the remote control in the alert mode, the door open signal and alert by Beep or vibration Engine start signal which shows the blinking lights on the LCD and the wheels rotating when the vehicle is started by the remote control or other setting in the mode.In the alert mode, the trunk is opened by keys or other tools without the remote control. When detected, the trunk icon on the LCD will blink and Beep or If the trunk open signal is notified, the hood icon on the LCD blinks when the hood is opened randomly in the alert mode, and the hood open signal alerted by the beep or vibration, and the alarm signal is detected on the additional sensor in the alert mode. The corresponding icon blinks and selectively detects various types of detection signals such as optional sensor 1 or 2 detection modes that are notified by Beep or vibration.

If the state change signal continues to be received for a predetermined state change time, the controller 23 determines that a change has occurred outside the vehicle, and sends a signal to the alarm means so as to alert the user or administrator to the fact. .

If the user does not respond to the alarm, the alarm sounds for a predetermined time. After that, the alarm sounds periodically on the remote control. If the user does not receive the remote control in the unreceivable area, the alarm is stored in the vehicle. When you can communicate with the remote control again, the remote control will resend the alarm.

On the other hand, the present invention, if the sensitivity setting of the predetermined shock sensor 50 is necessary, that is, when there is a lot of outside noise or if you park the car in a quiet residential area to increase / decrease the sensitivity of the portable device ( 10. The setting buttons 72a, 72b and 72c of the sensitivity setting device 70 and the display device 14 showing the set contents in real time are inputted to maintain the desired sensitivity.

To this end, when the sensitivity setting device 70 inputs a specific signal necessary for impact sensor sensitivity control, the output signal is transmitted to the control unit 23 through the signal transmission / reception unit 22, and the control unit 23 is a shock sensor ( Compared with the reference value set in step 25), if the value does not match, the electric signal is transmitted to the shock sensor module 80 and the sensitivity preset in the shock sensor 25 is initialized.

At this time, the control unit 23 receiving the specific output signal of the sensitivity setting device 70 analyzes the code received from the signal transmitter / receiver 22 and transmits the sensitivity leveling signal value to the impact sensor 25 to adjust its sensitivity. Done.

When the shock sensor 25 detects a shock, a minute alternating current waveform is generated, so the amplifier 82 amplifies the minute electric signal at this time, and the amplified signal is a DC circuit using the rectifier circuit of the rectifier 84. After conversion to the output to the comparator 86, the comparator 86 compares / judges the input DC signal and the reference voltage and inputs the output signal to the controller 23 according to the length of the input signal The alarm means is controlled by determining the presence or absence of the impact, that is, the strength.

For example, if the remote controller of the portable device sets the level to "1" and transmits it to the control unit, the control unit determines that the shock detection signal has a length of 0.1 seconds or less from the shock sensor, and determines that the primary shock is higher. When input, it is recognized as a secondary shock.

And if the level is set to "3" in the remote control, the control unit determines that the impact shock signal is input from the shock sensor with a length of less than 0.3 seconds as the primary shock, and if the signal is input longer than that, the second shock is input.

The time setting at this time may be changed arbitrarily by the program.

<Example>

Referring to the accompanying drawings, a method of adjusting the sensitivity of the shock sensor will be described.

The ON / OFF and detection level of the shock sensor mounted on the vehicle is set by using the setting button.

As described above, according to the present invention, sensitivity of the shock setting device 70 and the shock sensor 25 for outputting a specific signal to control the shock sensor 25 for controlling the sensitivity of the shock sensor are set. Since the shock sensor module 80 is provided to remotely control the sensitivity of the predetermined shock sensor 25 to suit the surrounding situation, the user may directly adjust the sensitivity of the shock sensor as in the prior art. There is an advantage that can reduce the inconvenience.

In addition, the present invention by using a portable device, such as a remote control for starting a vehicle or a portable remote control such as an anti-theft device provided for the user's convenience, it is possible to reset the sensitivity of the preset sensor to match the surrounding environment of the sensor The noise damage caused by frequent operation can be reduced.
