Problems solved by technology

[0004] (1) The problems caused by the patch process cannot be fully exposed through manual visual inspection, and the efficiency of complete manual visual inspection is low
[0005] (2) PCBA debugging requires professional debugging personnel to complete, and there are human misjudgments
[0006] (3) It used to take 15 minutes to debug and complete a PCBA board, but it only takes 2 and a half minutes to use the automated test system, which is relatively low in efficiency compared to the existing ones
[0007] At present, the debugging of GNSS products in China has not realized the automatic debugging and testing method

Embodiment Construction

[0070] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0071] see Figure 1 to Figure 4 As shown, the method for realizing the automated testing of GNSS products based on functional testing comprises the following steps:

[0072] (1) Burn the kernel to burn the kernel of the GNSS product mentioned above; the GNSS product mentioned here mainly refers to the PCBA main board of the GNSS product. The kernel programming described here mainly refers to downloading the program of the function to be realized by the GNSS product to the PCBA main board, so that the subsequent function test module can perform functional test on the GNSS product.

[0073] (2) burning kernel judges whether described kernel burning is successful;

[0074] (3) If the kernel burning success described, then function test module tests described GNSS product, and output test result to test resu...

Abstract

The invention relates to a GNSS (Global Navigation Satellite System) product automatic test method based on function test. A function test module is in connection with a detected GNSS product through a test point, controls the on-off of power-on, burning and detection switches, and successively completes function model test of the GNSS product so as to detect whether each function module of the GNSS product is normal. According to the invention, after the surface mount of the GNSS product, a common operator of a supplier can directly complete mainboard debugging and aging work, requiring no professional debugging personnel to perform test, thereby simplifying a whole debugging process, minimizing manual operation, improving test efficiency and accuracy, meanwhile reducing surface mount quality costs, promoting the surface mount process improvement of the supplier, and realizing win-win.

Description

technical field [0001] The invention relates to the field of GNSS products, in particular to the technical field of functional acceptance of GNSS products, and specifically refers to a method for realizing automatic testing of GNSS products based on functional testing. Background technique [0002] GNSS (the abbreviation of Global Navigation Satellite System, the Chinese translation is called global navigation satellite system) PCBA patch is completed, the quality and quality personnel will conduct an appearance inspection on it, and then professional debugging engineers will be required to manually debug it. If there is any problem in the debugging process, It is necessary to check one by one according to the PCB schematic diagram. After the debugging is passed, it needs to be manually erected for a long time high-temperature aging screening. After high-temperature aging, it needs to be debugged and confirmed again. Only through the above process can the PCBA circuit board b...
