A method and system for plate shape detection of a mobile terminal

Abstract

The invention provides a mobile terminal board type detection method and system, and is used for detecting the mainboard type of a mobile terminal. An active crystal oscillator used for indicating the mainboard type, and a controller are arranged on the mainboard of the mobile terminal. The controller detects frequency of the output signal of the active crystal oscillator. The mainboard type is identified according to the frequency of the output signal of the active crystal oscillator and mainboard type information is outputted. The active crystal oscillator used for indicating the board type is arranged on the mainboard of the mobile terminal, and the active crystal oscillator outputs the signal of the fixed frequency; and the frequency of the output signal of the active crystal oscillator is detected, and the board type is identified according to the frequency. The active crystal oscillator has stable frequency of the output signal and high precision so that a wide range of identification does not need to be set for one board type, and thus the method is suitable for multiple board types without false detection; meanwhile, the active crystal oscillator has the characteristics of stable frequency and high precision so that the crystal oscillator is judged to be damaged when frequency abnormity is detected and timely prompting is performed.

In the prior art, the invention patent application with the application number CN201410354721.2 provides a detection device and detection method for the main board type of a mobile terminal. The power management module outputs the power supply voltage to the main board type detection module, and the main board type detection module is The main board resistor divides the power supply voltage and outputs the divided voltage. The power management module calculates the resistance value of the main board resistor according to the power supply voltage and the divided voltage. According to the resistance value, the main board type can be identified. Small differences between end products and easy false detection

However, considering the error factor in the technical solution of the application, it is necessary to map a voltage range to a motherboard type (for example, 0.6V to 1.0V corresponds to a motherboard type). ), each voltage range in the technical solution of this application will inevitably be compressed, which will easily cause false detection; in addition, when the resistor used for voltage division is damaged, the main board type cannot be detected, causing false detection
