Automatic connection system for detecting narrowband power line carrier module of single phase watt hour meter

Abstract

The invention relates to an automatic connection system for detecting a narrowband power line carrier module of a single phase watt hour meter. A transfer box provided with the narrowband power line carrier module of a to-be-detected single phase watt hour meter is conveyed to pass by a feeding streamline, an unstacker, an electromagnetic shielding box, a transmission line and a stacking machine in sequence; electromagnetic shielding box is provided with a detection module, the detection module is used for detecting multiple performance of the narrowband power line carrier module of the singlephase watt hour meter, and the detection frequency band of the detection module is 10kHz to 500kHz. Automatic splitting of whole stock module of the narrowband power line carrier module of the singlephase watt hour meter can be achieved, qualified products are automatically stacked and are connected with an warehouse storage system, thereby reducing the investment of manpower resources in a module unpacking and stacking process and reducing the labor intensity, and the automatic connection system is suitable for batch module detection and provides guarantee for improving the detection systemof the whole module.

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 narrow-band power carrier modules of single-phase electric energy meters. 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 c...

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
