Automatic connecting method for broad-band power line carrier module detection

Abstract

The invention relates to an automatic connecting method for broad-band power line carrier module detection. According to the method, a loading assembly line, an unstacking machine, an electromagneticshielding box, a conveying line, a stacking machine, an under-fill box buffering conveying line, a six-axis manipulator and a defective product conveying line are included, and circulating boxes containing to-be-detected broad-band power line carrier modules are conveyed sequentially to pass through the loading assembly line, the unstacking machine, the electromagnetic shielding box, the conveyingline and the stacking machine. The method is characterized in that a detection module is mounted in the electromagnetic shielding box; and the detection module is used for detecting multiple properties of the broad-band power line carrier modules and has the detection frequency band ranging from 2 MHz to 20 MHz. Whole stacks of the broad-band power line carrier modules are split automatically after being output, and qualified products are stacked automatically and are connected with a warehousing system, so that the manpower resource input during module unstacking and stacking is reduced, thelabor intensity is reduced, the method is suitable for batch detection of the modules, and improvement of the efficiency of the whole module detection system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric measurement and electric energy measurement, in particular to an automatic connection method for wideband power carrier module detection. Background technique [0002] Power carrier communication is a communication technology that uses power lines for data transmission, that is, using the existing power grid as a signal transmission medium, so that the power grid can transmit data while transmitting power. At present, according to the different frequency bands used, low-voltage power line carrier communication is generally divided into narrowband power line carrier communication (10kHz~500kHz) and broadband power line carrier communication (2MHz~20MHz). The following aspects: (1) communication rate, in general, the wider the transmission signal bandwidth, the higher the transmission rate; (2) noise interference, low frequency area; (3) difference in communication distance, at present, the narrowb...

Problems solved by technology

[0003] Although all broadband and narrowband carrier module manufacturers are equipped with their own module quality inspection systems in the module production process, they are all based on the feeding inspection method of a single product, and the entire inspection process still needs manual operation, which is less efficient. Low cost, relatively high cost, not suitable for batch testing requirements of metering center modules and full automation requirements

As a part of the entire module production system, the carrier module detection system cannot be well compatible with the module storage and storage system in the existing production system, and usually requires manual intervention to complete the loading and unloading of the product, resulting in high labor costs and low verification efficiency
