Automatic connection system used for detecting broadband power carrier-wave module of three-phase kilowatt-hour meter

Abstract

The invention relates to an automatic connection system used for detecting a broadband power carrier-wave module of a three-phase kilowatt-hour meter. The automatic connection system comprises a loading assembly line, an unstacker, an electromagnetic shielding box, a conveyor line, a stacker, an un-full box buffer conveyor line, a six-axis mechanical hand and an unqualified objet conveyor line, wherein a turnover box equipped with a to-be-detected broadband power carrier-wave module of the three-phase kilowatt-hour meter is sequentially transferred to pass through the loading assembly line, the unstacker, the electromagnetic shielding box, the conveyor line and the stacker. The automatic connection system is characterized in that a detecting module is mounted in the electromagnetic shielding box, wherein the detecting module is used for performing multi-performance detection on the broadband power carrier-wave module of the three-phase kilowatt-hour meter, and has a detecting frequencyband of 2 MHz-20 MHz. The automatic connection system can realize ex-warehousing and automatic dismounting of a stacking module of the broadband power carrier-wave module of the three-phase kilowatt-hour meter, automatically stacks qualified products and is connected with a warehousing system, reduces manpower resource investment in a module unstacking process, reduces labor intensity, is suitable for batch module detection, and provides guarantee for improving efficiency of the whole module detecting system.

Description

technical field [0001] The invention belongs to the technical field of electric measurement and electric energy measurement, in particular to an automatic connection system for detection of a broadband power carrier module of a three-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 co...

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
