Embodiment Construction

[0021] Referring to the structural principle diagram shown in FIG. 1 , the computer 1 is connected to the test connection board 2 through a serial port line, and the test connection board 2 is connected to the communication module 9 of the vehicle-mounted device 3 through a slot. The vehicle-mounted device 3 includes a single-chip microcomputer 8 , a voice chip 7 , a GPS module 6 , a GSM module 4 and related peripheral components 5 . The present invention uses the computer 1 to simulate the control center to send instructions, and directly communicates with the vehicle-mounted device 3 through the test connection board 2, replacing the communication mode in which the control center transmits short messages to the vehicle-mounted device through the GSM module through the mobile wireless network.

[0022] Referring to the schematic diagram of the connection board shown in Figure 2, the test connection board 2 is specially designed for testing vehicle-mounted devices, and has the ...

Abstract

A test method based on remote control vehicle device includes setting up physical connection between computer and vehicle device, sending control command to vehicle device directly by computer analog control center through serial interface, setting up product new test piece and selecting test item, generating a short message command by computer as per PDU format to execute test automatically, printing out test report and making ex-factory initial setting on qualified product.

Description

technical field [0001] The invention relates to a test method in the field of GSM communication, in particular to a test method based on a remote control vehicle-mounted device. Background technique [0002] In order to ensure the normal operation of vehicle-mounted products, strict testing is often required before leaving the factory. The current method is: use a mobile phone or a computer to connect to a GSM communication module to send a short message, and send it to the vehicle-mounted device through the operator's relay to remotely control the vehicle. The GSM communication module is responsible for the communication between the vehicle-mounted device and the control center, and the control center realizes the remote control of the vehicle-mounted device by sending short messages to the GSM communication module. [0003] Further, the control center must send a short message through the GSM communication module to send commands to the vehicle-mounted device. The short m...
