Automatic connection system used for detection of single-phase electric energy meter broadband power carrier module

Abstract

The invention relates to an automatic connection system used for detection of a single-phase electric energy meter broadband power carrier module. A circulation box containing the single-phase electric energy meter broadband power carrier module to be detected sequentially carries out conveying through a feeding assembly line, an unstacker, an electromagnetic shielded box, a conveying line and a stacking machine, a detection module is arranged in the electromagnetic shielded box and is used for carrying out multi-property detection on the single-phase electric energy meter broadband power carrier module, the detection frequency band of the detection module ranges from 2 MHz to 20 MHz, stock removal and automatic splitting of the whole single-phase electric energy meter broadband power carrier module can be achieved, qualified products are automatically stacked and connected with a storage system, manpower resource input in the module de-stacking and stacking process can be reduced, labor intensity is reduced, the system is suitable for batched module detection, and guarantee is provided for improving efficiency of the whole module detection system.

Description

technical field [0001] The invention belongs to the technical field of electric measurement and electric energy metering, in particular to an automatic connection system for detecting a broadband power carrier module of a single-phase electric energy meter. 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 communi...

AI Technical Summary

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
