Problems solved by technology
[0002] In the test process of the existing car radio, an external power supply and audio test equipment, connection harness, etc. are required, which is inconvenient to carry when going out, and it needs to be assembled on site, and professional personnel are required to connect. The entire test process can only be completely Manually operate the product and observe the value of the instrument to judge whether the product is good or not, the error rate is high and the requirements for workers are also high
Because there is no computer in the existing test, once the customer returns the product, the test data of the product cannot be queried

Embodiment Construction
[0014] Below in conjunction with accompanying drawing, the vehicle-mounted radio suitcase type test system of the present invention is described in further detail.
[0015] Such as figure 1 , figure 2 As shown, the vehicle radio suitcase test system of the present invention includes a test box 3 and a test circuit 2 arranged in the test box 3 .
[0016] In the test circuit 2, the product sensor is coupled and connected to pin 8 of the main control chip. During the test, put the product into the jig of the test box 3, the operator scans the product serial number to obtain the complete product serial number, the mobile terminal 1 will record the serial number and call the corresponding test configuration file, and then send to The test circuit 2 issues instructions, specifically, the instructions are transmitted to the main control chip via the CAN bus adapter and the CAN bus driver coupled and connected to each other.
[0017] At this time, the main control chip controls th...

The invention discloses a suitcase type test system for a car radio. The suitcase type test system comprises a test box and a test circuit arranged in the test box. According to the suitcase type test system for the car radio, all functions of the car radio in the car loading simulation state can be tested automatically, and the suitcase type test system product has the advantages of small size, portability, capacity of fully-automatic testing and the like, can be placed at a client for testing a product arriving after long-distance transportation and prevents products failing on the way from flowing to the client; and the defects of low efficiency and high judgment error rate of a worker of traditional manual detection are overcome.
Description
technical field [0001] The invention relates to the electrical field, in particular to a suitcase type test system for a vehicle radio. Background technique [0002] In the test process of the existing car radio, an external power supply and audio test equipment, connection harness, etc. are required, which is inconvenient to carry when going out, and it needs to be assembled on site, and professional personnel are required to connect. The entire test process can only be completely Manually operate the product and observe the value of the instrument to judge whether the product is good or not, the error rate is high and the requirements for workers are also high. Because there is no computer in the existing test, once the customer returns the product, the test data of the product cannot be queried. Contents of the invention [0003] The purpose of the present invention is to provide a car radio suitcase type test system which can realize automatic test. [0004] In ord...
