Description

  The present invention is a car handle lock for anti-theft alarm device, and it is a durable mechanical handle closure mechanism, equipped with an anti-theft alarm circuit for precise anti-theft detection, and can carry long distance anti-theft alarm and remote control. It is a handle lock that can be linked with an alarm.

  Many people use mechanical anti-theft locks such as handle locks and locks to keep their cars from being stolen. However, no matter how strong these mechanical anti-theft locks are, they can be opened in a timely manner when they encounter a car sif, and not a full-effect anti-theft. If you have enough time and have the necessary equipment, it is really easy to lock. Besides, electronic anti-theft devices are often used now. We believe that the precision detection function of the electronic anti-theft device will prevent theft, but these devices work with the main battery of the car and use its power to prevent theft by detecting vibrations. A detector on the circuit detects the state of the vehicle, and if the vehicle condition is detected as abnormal such as shock vibration or door lock being broken, it sends a signal to the anti-theft alarm device on the circuit and makes a huge volume. Make a sound and trick a thief.

  However, since such an electronic antitheft device uses the power of the main battery of the car, the device work is difficult and the track is easily cut. In the past, the handle lock and electronic anti-theft machine were separate products, and if you wanted them to work at the same time, you had to buy two types of products. I have no money. In addition, the anti-theft machine sounds an alarm due to the surrounding noise (lightning, fireworks, large cars, etc.). If this happens many times, you will not be able to use or use the alarm as you would a “wolf man”. Until now, the alarm device only emits an alarm sound, so unless the vehicle owner is in the immediate vicinity, it does not know that the alarm device will be available and cannot take appropriate measures. In reality, the car stays away from the house, so the sound of the anti-theft alarm so far has no meaning for the thief, and it has no utility that the owner can take immediate action.

  The present invention provides an electronic precision anti-theft detection and mechanical and robust car anti-theft alarm. The contents are a mechanical anti-theft lock that can be fixed to the steering wheel of an automobile, and an electronic anti-theft alarm circuit is attached to the main body, and the anti-theft alarm circuit has an ultrasonic detection unit and an atmospheric pressure change detection unit.

Thus, when the car is stolen, the lock theft prevention alarm circuit activates the antitheft alarm and simultaneously sends a warning signal from the radio wave transmission unit to the portable alarm device. Then, the user can immediately perform the necessary treatment. The user also uses the infrared signal transmission unit of the portable alarm device to set the lock theft prevention alarm circuit to the alarm operation delayed activation mode by remote control, and when the user gets out of the car or gets into the car This avoids accidental activation of the anti-theft alarm system.

During the alarm operation, if an abnormal vibration, sudden pressure change or object movement is detected inside the vehicle, a strong anti-theft alarm sound and flashing light The anti-theft alarm signal is sent to the corresponding form alarm device by radio wave.

  As shown in FIG. 3, the anti-theft circuit operates in response to an anti-theft detection signal. Under an anti-theft alarm situation, when an abnormal signal is issued, the alarm circuit emits a huge sound and makes a thief with a strong flash.

The pressure change detection unit continues to detect positive and negative pressures, and an alarm is activated when there is negative pressure and no positive pressure is detected. If there is positive pressure and you do not feel negative pressure, the negative pressure will not operate within 200MS after the positive pressure disappears.

After the test wave is amplified and compared, it is output to the CPU for program discrimination.

  The present invention has the above-described arrangement and will be described in more detail in the flowchart of FIG. 8. The anti-theft alarm circuit and the portable alarm device interact with each other, and the operation flow is as follows: The anti-theft alarm circuit is off, and the portable alarm is in a standby state. In this state, the portable alarm can detect the signal from the anti-theft alarm, but does not display the LCD screen and saves power. When the key is turned on, the anti-theft alarm circuit starts to operate, a long sound is heard, a low voltage is detected, the radio wave transmission unit transmits a switch-on signal, and the portable alarm is switched on. Then, it will be in a standby state. When the voltage detection result of the antitheft alarm circuit is low in the above switch-on procedure, a third low sound wave is transmitted and an alarm is sent, and the radio wave transmission unit is switched on simultaneously with the switch-on signal. Send a voltage signal. When the portable alarm device receives the switch-on signal and switches to the switch-on state, it also indicates that the anti-theft alarm circuit is in an insufficient power state.

  Continuing the talk, the anti-theft circuit operates with a 30 second delay in going out, and the user gets out of the car and closes the door in sufficient time. At the same time, the anti-theft alarm circuit confirms the password by making a signal back and forth with the portable alarm device for 30 seconds when going out. There are more than one million of these codes, and they are all written on the IC. When checking the password, the operation mode of the portable alarm device is set to the detection mode, and the infrared signal transmission unit meets the infrared detection unit of the antitheft alarm circuit to automatically detect the pair catch.

  When the code catch is finished, the anti-theft alarm circuit enters a warning state, and after 10 minutes, the vehicle owner is detected and transmitted. In other words, at 10 minutes, the radio wave transmits a test code signal, a short buzzer sounds, and an online graphic is displayed on the LCD display.

  When the detection unit of the anti-theft alarm circuit is activated in the anti-theft alarm state, the alarm clock flashes for 10 seconds, the alarm buzzer, and the radio wave transmission unit wave RF and code signal are transmitted. When the RF alarm code signal is received, the anti-theft alarm is activated, and the above signal is displayed on the LCD.

  The anti-theft alarm circuit is in an anti-theft alarm state. If the key is not turned off or the set condition is not canceled, the anti-theft alarm circuit enters the anti-theft alarm state when the set alarm operation time is reached. When the key is turned off, the power supply of the anti-theft alarm circuit is immediately turned off, the operation is stopped and at the same time an off signal is transmitted by radio waves, and when the portable alarm device receives the off signal, it is converted into a standby mode.

  Finally, when the user enters the vehicle and releases the anti-theft alarm device, the anti-theft alarm circuit can be delayed and the alarm operation procedure can be re-moderated, thereby avoiding erroneous activation of the anti-theft alarm system. The flow is shown in FIG. The anti-theft alarm circuit is in a switch-on anti-theft alarm state, the infrared transmission unit of the portable alarm device targets the infrared reception unit of the anti-theft alarm circuit, presses the function button, and inputs a delay alarm code When the anti-theft alarm circuit confirms the infrared delay alarm code, it enters into a time counting waiting state (initial setting is 20 seconds), and the radio wave transmission unit of the anti-theft alarm circuit transmits a delay confirmation code signal, When the portable alarm device receives the confirmation code signal, the buzzer sounds and confirms four short tones. If the anti-theft alarm detection is not touched within the above-described counting waiting time, the anti-theft alarm circuit returns to the anti-theft alarm state when the waiting time has passed. If the vehicle owner enters the vehicle and touches the anti-theft detection unit during the equal waiting time, the anti-theft alarm circuit enters the delay alarm time mode (set time is 30 seconds), and the user only has to stay within this delay time. The switch must be switched off to cancel the anti-theft alarm circuit setting. Otherwise, when the delay time expires, the anti-theft alarm circuit erroneously activates the anti-theft alarm operation described above.
