After the system is powered on and a POST self-test program is started, the self-test process comprises the following steps:
in step 410, it is detected whether the audio chip 213 is normal, if not, a malfunction alarm is given, and if normal, the next module is continuously detected.
In step 412, it is detected whether the WiFi module 214 is normal, if not, a malfunction alarm is given, and if so, the next module is continuously detected.
In step 414, it is checked whether the battery 260 is normal, and if not, a malfunction alarm is given, and if so, the next module is continuously checked.
In step 416, it is checked whether the memory card 220 is normal, and if not, a malfunction alarm is given, and if so, the next module is continuously checked.
In step 418, it is detected whether the microphone 211 is normal, if not, a malfunction alarm is given, and if normal, the next module is detected continuously.
In step 420, whether the horn 212 is normal is detected, if not, a fault alarm is given, and if so, the POST self-checking process is ended.
The judgment on whether each module is normal is that after the intelligent test terminal 200 is powered on, each module should be powered on normally, if the module is detected to be powered on normally, the module is normal, and if the module is not powered on, the module is abnormal. For the sound pick-up 211 and the speaker 212, it is possible to test whether the sound pick-up 211 can record sound normally and the speaker 212 can broadcast sound normally by adding a test program to the self-test program 230. For the WiFi module 214, a piece of test data may be added to the self-test procedure 230, and the WiFi module 214 is used to transmit and/or receive the test data to determine whether it can implement the transceiving function. The invention does not limit the specific process of the POST self-test, and a person skilled in the art can perform the power-on self-test on each module in the intelligent test terminal 200 in various ways.
The malfunction alarm may be indicated by the LED indicator 240 through its color, flashing manner, etc., or may be indicated by other manners such as sound, etc.
In the embodiment shown in fig. 2, an LED indicator 240 is used to indicate the operating state of the intelligent testing terminal 200.
