Problems solved by technology
[0002] With the promotion of mobile phones, the security risks and threats of mobile phones are becoming more and more prominent. In particular, the operating environments of smart phones are mostly open operating systems, such as Windows Mobile, Android, etc., and their open interfaces allow the implantation of various software , when a user uses a smart phone to download various application software through the network or PC, various viruses and backdoors will inevitably appear on the mobile phone. Some backdoors and viruses can remotely turn on the power of the mobile phone and monitor the environmental conditions of the mobile phone in real time; It’s just that the backlight of the screen is turned off, but other modules such as the radio frequency are not turned off, resulting in a false shutdown
These potential safety hazards cannot be resolved if only software processing methods are adopted
[0003] In view of the above technical problems, it is necessary to adopt a safety detection and control device and method for switching on and off the mobile phone, so as to prevent the mobile phone from being illegally powered on when it is attacked by viruses, causing the mobile phone to be monitored, or a false shutdown occurs after the user shuts down the mobile phone.

Embodiment Construction
[0017] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0018] The device provided by the present invention is based on the existing structure of ordinary mobile phones, adding a mobile phone switch button detection control module composed of a control CPU, a trigger (such as a D trigger) and an AND gate device. It is characterized in that: (1) the control CPU respectively coupled with the mobile phone switch button and the AND gate device; The CPU and the D flip-flop are connected to the analog switch control port of the power supply of the radio frequency module through the AND gate device, and control the power supply of the radio frequency module to be turned on and off. The structural relationship between the devices added in this design method and other components of ordinary mobile phones is as follows: figure 1 shown. In the figure, the application processor, the radio freq...

The invention discloses a mobile phone on and off security detection and control device, which comprises a control CPU, a mobile phone on and off button detection control module, an application processor and a mobile phone on and off circuit. The invention also discloses a mobile phone on and off security detection and control method. Only when a user presses an on button, a mobile phone radio frequency module is turned on to supply power. As he mobile phone radio frequency module cannot be turned on to supply power if the on button is not pressed, remote illegal turning on and intercepting of the mobile phone infected with viruses are avoided. The system is bound to stop the power supply of the mobile phone radio frequency module as long as the system detects the user presses an off button to turn off the mobile phone, so false turning off of the mobile phone is avoided.
