Problems solved by technology

[0008] However, this technology also has deficiencies: firstly, it is impossible to call the police and remind everyone in time during the theft, which cannot effectively prevent the theft from happening; Loss, after all it takes a police officer; worst case, if the thief doesn't have access to the stolen laptop, tracking is impossible at all

Embodiment 1

[0054] see Figure 4 , The anti-theft alarm device in this embodiment is applied to a notebook computer, and includes a touch sensor, an embedded chip on the motherboard of the notebook computer, a sounding device and a built-in keyboard.

[0055] Wherein, the embedded chip can adopt NS87591E / L (National Semiconductor company product) commonly used in many notebook computers at present.

[0056] The touch sensor is located on the shell of the laptop, and its output pin is connected to one of the pins Wakeup Pin embedded in the chip (for example, the 29th pin, namely EXTWIN21). The touch sensor of the notebook computer casing can be one large touch sensor or many small touch sensors, which are used to sense external contact disturbances. The touch sensor can use a laptop computer battery or a power supply circuit such as an RTC or an additional battery to provide working power.

[0057] The sounding device is integrated on the motherboard of the notebook computer; the embedde...

Embodiment 2

[0066] see Figure 5 , The anti-theft alarm device of this embodiment is applied to a notebook computer. Its working principle is roughly the same as that of the anti-theft alarm device in Embodiment 1, with one difference being that the state detection unit adopts a resistive pressure device. Another difference is: the alarm unit also includes a built-in mobile phone module of the notebook computer, which also uses the built-in mobile phone module of the notebook computer to send a short message to the owner of the notebook computer to realize the alarm while sounding the alarm. Another difference is that: in addition to switching the anti-theft alarm device through the built-in keyboard, the anti-theft alarm device can also be switched on and off through the built-in mobile phone module.

[0067] Some notebooks are currently integrated with mobile phone modules (such as GPRS), and the communication function can be realized as long as the user identification module (such as ...

Abstract

An antitheft alarming device of portable digital equipment consists of state detection unit, alarming unit, data processing unit, operation mode switching over unit.. It is featured as generating state signal and sending it to data processing unit when disturbance on portable digital equipment is detected out by detection unit and analyzing state signal by processing unit and driving antitheft alarming unit to realize alarm.

Description

technical field [0001] The invention relates to digital equipment anti-theft technology, in particular to a portable digital equipment anti-theft alarm device. Background technique [0002] With the development of information technology, various portable digital devices, such as notebook computers, personal digital assistants (PDAs), and palmtop computers, are increasingly popularized. Because portable digital devices are light, thin, and easy to carry, they can open the door for people to communicate timely and conveniently as well as acquire and process information. They are especially suitable for mobile office, mobile business, and daily life. In various occasions, it is gradually adopted by people from all walks of life, and its market is getting bigger and bigger, and the number of people who own portable digital devices is also increasing. [0003] Portable digital devices are valuable and easy to carry, so they are easy to be coveted by thieves and cause property lo...
