Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] Such as figure 1 As shown, the circuit diagram of the alarm signal generator in the present invention is given, which is composed of a battery 1, a vibration sensor 2, a wireless transmitting chip 3, an encoding circuit 4, and a transmitting antenna 5. A switch is arranged on the positive pole of the battery 1, and the battery 1 The negative pole of is the power ground. The vibration sensor 2 is connected in series with the resistor R1 to the positive pole of the battery 1 and the ground of the power supply. The vibration sensor 2 is composed of a circular metal sheet at the center, a metal ring at the periphery and a metal ball on the circular metal sheet. The circular metal sheet and the metal ring are respectively drawn out through wires to form two terminals of the vibration sensor 2 . When the vibration sensor 2 vibrates, the metal ball wi...

The invention provides an antitheft wireless alarm which is provided with an alarm signal generation circuit and an alarm signal reception circuit. The alarm signal generation circuit is composed of a storage battery, a vibration sensor, a wireless emission chip and an encoding circuit. The alarm signal reception circuit is composed of a signal reception circuit, a wireless reception chip, a voltage stabilization chip and a buzzer. When an unlawful person touches an item (such as a vehicle), the pulse generated by the on / off state change of the vibration sensor turns on the power supply of the wireless emission chip, so that the wireless emission chip transmits its own code in the form of a high frequency number signal. When the wireless reception chip recognizes that the received signal is encoded in accordance with its own code, the wireless reception chip outputs an alarm signal that causes the buzzer to be turned on to alert the person (such as the owner) to the theft of the item being monitored, so that the corresponding measures are taken and the property loss is avoided.
Description
technical field [0001] The invention relates to an anti-theft wireless alarm device, more specifically, an anti-theft wireless alarm device composed of an alarm signal generator and an alarm signal receiver. Background technique [0002] Anti-theft alarm is an alarm device applied to anti-theft equipment. For example, anti-theft alarms can be set on vehicles and safety doors. Theft, take appropriate measures in time to avoid property loss. The anti-theft alarm on the existing vehicle usually adopts the form of an alarm on the vehicle. When someone touches or opens the vehicle, the alarm in the vehicle can send out an alarm signal to warn and intimidate the thief and cause the alarm of the surrounding people. Pay attention, to achieve the purpose of scaring away the thieves. But this form of alarm can not send the information that the vehicle is being stolen to the car owner in time, causing the car owner to not be able to detect and stop the act of stealing the vehicle in ...
