Problems solved by technology
[0005] (1) Due to the spatial coupling factor of the high-frequency carrier signal, the carrier signals within a few meters will interfere with each other, and it is difficult to realize the true one-drag multi-station parallel detection;
[0006] (2) The setting or arrangement of each test item is not reasonable enough, and there are problems of insufficient comprehensiveness or low detection efficiency

Embodiment Construction
[0037] The implementation of the detection method of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0038] Such as figure 1 As shown, the automatic detection system of the present invention mainly includes two parts: PC end (host computer) and equipment end (this embodiment takes the fixture with PCBA veneer slot as an example, and the fixture is a common device in the detection field ), the PC end communicates with the device end through the serial port.
[0039] The PC side is used to configure the detection parameters and display the detection results;
[0040] The device end includes a trigger switch which can be mounted inside or outside the device end as required to provide signals to the main control board when the closure is closed and when it is open.
[0041] A pressing device is installed on the outside of the equipment, and multiple stations are designed as required. Each station is equipped with a...

The invention discloses an automatic detection system and method for a PCBA single board of a broadband power line carrier communication module, which solves the problem of carrier signal space coupling interference in the detection process by adopting shielding measures and adding special interference signals; adopts multi-station parallel detection This method greatly saves manpower, equipment and time costs; the supercapacitor charging function detection is performed simultaneously with other detection items to improve detection efficiency. The automatic detection system and method of the present invention are very suitable for large-scale detection of the performance and function of newly assembled PCBA single boards in the production line.
Description
technical field [0001] The invention relates to the technical field of broadband power line carrier communication, in particular to a detection system and method. Background technique [0002] With the introduction of concepts such as "Strong Smart Grid" and "Ubiquitous Power Internet of Things" in recent years, the power consumption information collection system has developed from simple power data collection to intelligent, informatized, automated, and interactive. Meter terminal equipment builds a large and efficient communication network between users and grid companies, thereby realizing high-speed transmission of power, information, and application data, and remote home appliance monitoring and other functions. [0003] Compared with other communication technologies, broadband power line carrier communication technology uses low-voltage power lines as the transmission medium, which has the advantages of rich line resources, high transmission rate, and low network const...
