Technical Field

Background

At present, an intelligent terminal or an IOT product generally has only one SD (secure digital) memory card slot, and only one SD memory card can be placed at a time. When the intelligent terminal is used for carrying out compatibility test on the SD card, different SD cards can only be replaced manually, so that the efficiency is low and the manpower is wasted.

Currently, there is an automatic SD memory card compatibility test system for a vehicle mounted radio and tape player. Including control center, on-vehicle radio and tape player and the SD memory card that awaits measuring, still include: the SD switching circuit is used for connecting the SD memory cards to be tested to the vehicle-mounted radio and cassette player and switching the connection and disconnection between the SD memory cards to be tested and the vehicle-mounted radio and cassette player; the USB communication circuit is connected between the control center and the SD switching circuit and is used for receiving a control command of the control center and controlling the switching action of the SD switching circuit; the audio conversion circuit is connected between the vehicle-mounted radio and player and the control center and is used for converting the audio signals output by the vehicle-mounted radio and player into signals which can be identified by the control center; and the USB port electricity stealing circuit is connected with the control center and used for stealing voltage from the control center and supplying power to the SD switching circuit and the audio conversion circuit.

However, when the above system is used to perform an automatic SD memory card compatibility test, after the PC sends a control command to control the SD switch circuit to connect the SD card to be tested, the radio and tape player needs to read the audio file in the SD card, output a corresponding audio signal, convert the audio signal by the audio switch circuit and input the audio signal to the PC, and the PC detects whether the SD card is compatible by determining whether the audio signal is received.

Therefore, the circuit architecture of the automatic test system for the compatibility of the SD memory card is complex, and when the compatibility test is performed, a radio and tape player is required to read the audio file in the SD memory card and input the audio signal to the PC, so that the test process is complex.
