Abstract
The utility model discloses a mobile phone mainboard circuit comprising a central processor, a communication unit, a display unit and an input unit. The communication unit, the display unit and the input unit are electrically connected with the central processor. The mobile phone mainboard circuit also comprises a self-destruction control unit and a self-destruction unit, the self-destruction unit is connected with the central processor or a power supply circuit in a mobile phone, and the self-destruction control unit is controlled by the communication unit or/and the input unit. When the mobile phone receives a self-destruction signal or the number of password inputting times for the input unit exceeds predetermined times, the self-destruction control unit drives the self-destruction unit to destroy the mobile phone circuit. The self-destruction unit and the self-destruction control unit are employed in the mobile phone mainboard circuit, so that the mobile phone circuit automatically destroys only when the effective self-destruction signal is generated, and the safety and reliability of the mobile phone are greatly improved.
Description
technical field
The utility model relates to a kind of cell phone mainboard circuit, especially a kind of cell phone mainboard circuit with self-destroying function.
background technology
Mobile phone is along with the reduction of price, and the expansion of function, spreads in daily life.Generally, mobile phone not only can be used for call, transmitting-receiving short message, also Internet enabled, smart mobile phone particularly, has possessed the function of a personal computer substantially, and it has and surfs the web, send micro-letter, instant messaging, can also preserve etc. with personal information.Especially in mobile phone, have mass communication personal information, pictorial information and message registration etc., once mobile phone is lost or be stolen, probably allow owner's personal information reveal, and makes troubles and perplex to owner's life.The existing mobile phone with self-destroying function, because its cell phone mainboard circuit design is unreasonable, self-destruction action more easily triggers, and therefore, the reliability of existing self-destruction cell phone mainboard circuit is not high enough, haves much room for improvement.
utility model content
In order to overcome the problems referred to above, the utility model provides a kind of cell phone mainboard circuit that can self-destruction when people illegally use mobile phone or receive self-destruction signal to society, to improve the safety and reliability of mobile phone.
The technical solution of the utility model is: a kind of cell phone mainboard circuit is provided, comprise central processing unit, communication unit, display unit and input unit, described communication unit, described display unit and described input unit are electrically connected to described central processing unit respectively, also comprise self-destruction control unit and self-destruction unit, described self-destruction unit is connected with the power circuit in described central processing unit or mobile phone, and described self-destruction control unit is subject to communication unit or/and the control of input unit; When mobile phone receives self-destruction signal or when the password number of times of input unit input surpasses pre-determined number, self-destruction control unit starts self-destruction unit and destroys mobile phone circuit.
As to improvement of the present utility model, also comprise AD conversion unit and image unit, described image unit is electrically connected to described central processing unit by described AD conversion unit, the analog signal that described AD conversion unit produces described image unit converts digital signal to, and this digital signal is exported to described central processing unit.
As to improvement of the present utility model, described display module is LCDs.
As to improvement of the present utility model, described input unit is touch input unit.
As to improvement of the present utility model, described communication unit is GSM communication unit, CDMA communication unit or WCDMA communication unit.
The utility model, owing to having adopted self-destruction unit and self-destruction control unit, like this, only has when having effective self-destruction signal, and mobile phone circuit just can self-destruction, has improved widely the safety and reliability of mobile phone.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment frame structure schematic diagram of the present utility model.
Embodiment
Refer to Fig. 1, what Fig. 1 disclosed is a kind of cell phone mainboard circuit, comprise central processing unit, communication unit, display unit, input unit, self-destruction control unit and self-destruction unit, described communication unit, described display unit and described input unit are electrically connected to described central processing unit respectively, described self-destruction unit is connected with the power circuit in described central processing unit or mobile phone, and described self-destruction control unit is subject to communication unit or/and the control of input unit; If stolen at mobile phone, robbed or lost after, in the time of need to carrying out self-destruction, owner can send self-destruction signal, as note etc., controls self-destruction control unit, by the central processing unit of circuit board of mobile phone directly and power supply short circuit, and central processing unit is destroyed; Or, be provided with startup password number of times in the mobile phone in advance, if user connects output password mistake while reaching pre-determined number, self-destruction control unit starts self-destruction unit and destroys mobile phone circuit; Certainly, preferably before reaching pre-determined number soon, point out, if reached several times, mobile phone circuit, by self-destruction, like this, can guarantee that normal user can not make because inputing number of times by mistake mobile phone self-destruction.
In the utility model, also comprise AD conversion unit and image unit, described image unit is electrically connected to described central processing unit by described AD conversion unit, the analog signal that described AD conversion unit produces described image unit converts digital signal to, and this digital signal is exported to described central processing unit.Described display module is LCDs.Described input unit is touch input unit.Described communication unit is GSM communication unit, CDMA communication unit or WCDMA communication unit.
