Remote switch type inductive theft-proof portable computer

Abstract

The invention discloses a remote switch type inductive theft-proof portable computer, which comprises a computer body and a power supply and is characterized by also comprising a sensor, a voltage comparator, a phase reverser and an alarm module, wherein the sensor is connected with the voltage comparator; the voltage comparator is also connected with the phase reverser; the phase reverser is also connected with the alarm module; and the power supply is connected with the voltage comparator, the phase reverser and the alarm module respectively. The invention adopts the technical scheme that only an alarm circuit, the sensor, a remote control component and a loudspeaker are arranged in the portable computer; the loudspeaker also can be a built-in sound box of a public laptop, so the loudspeaker has smaller volume, can be well arranged inside the laptop, does not influence the aesthetic degree of the laptop, and has good concealment effect; the alarm real-time property is high by adopting vibration induction alarm; the safety factor is high by using a remote switch to get rid of alarm; and because a battery adopts an anti-dismantling device, the alarm function is not closed due to power down.

Description

technical field [0001] The invention relates to a notebook computer, more specifically, to a remote switch type induction anti-theft portable computer. Background technique [0002] Traditional anti-theft measures for portable computers, such as anti-theft locks, password boxes, etc., are not enough to achieve very effective anti-theft effects, nor can they meet people's requirements for anti-theft of portable computers. Perhaps the alarm switch adopts a manually operated switch, and the common switch type is easily turned off directly by a thief; the password type operation process is cumbersome and inconvenient to use. Chinese invention patent application number 200610058720.9 discloses a kind of intelligent anti-theft alarm device based on mobile communication network, which provides the function of calling the police through the mobile communication network, and the switch of the alarm device is also controlled by the mobile communication network. The reason is that the...

[0002] Traditional anti-theft measures for portable computers, such as anti-theft locks, password boxes, etc., are not enough to achieve a very effective anti-theft effect, nor can they meet people's requirements for anti-theft of portable computers

Or the alarm switch adopts manual operation switch, the ordinary switch type is easy to be turned off directly by the thief; the password type operation process is cumbersome and inconvenient to use

Chinese invention patent application number 200610058720.9 discloses a kind of intelligent anti-theft alarm device based on mobile communication network, which provides the function of calling the police through the mobile communication network, and the switch of the alarm device is also controlled by the mobile communication network. The reason is that the mobile communication network is seriously affected by the communication environment. For example, calls are often dropped on trains and cars, causing communication failures; or communication is prohibited on airplanes.

Moreover, the switch of the device is controlled by SMS, the real-time performance is poor, and the delay of the switch is always inevitable; and the cost is relatively high
