Automatic detection method for narrow-band power line carrier modules of single-phase electric energy meter

Abstract

The invention relates to an automatic detection method for narrow-band power line carrier modules of a single-phase electric energy meter. The following steps are sequentially executed; firstly, feeding is performed; secondly, a detection module sequentially detects all products in a circulating box, and if bad products are detected, the positions of the bad products are calibrated; thirdly, afterdetection of the modules in the whole box is completed, the modules flow into a discharging conveying line; fourthly, when a next box reaches, a manipulator grabs bad products, and the next box is filled with qualified products in a supplementing manner, and then the circulating box filled with products flows to a stacking machine; and after stacking of the stacking machine achieves a set number,a warehousing discharging system transports the modules back to a warehouse to be stored. The method fills up the blank of metering and automatic production, warehousing and logistics, and testing ofstage grid carrier modules, the carrier replacement time among various procedures can be saved, time waste caused by equipment wire changing is avoided, the detection equipment cost is substantiallysaved, the space utilizing rate is increased, the procedure that the modules go out of the box and enter the box is avoided, manual participation is reduced, and the product detection efficiency can be substantially improved.

Description

technical field [0001] The invention belongs to the technical field of electric measurement and electric energy measurement, in particular to an automatic detection method for a narrow-band power carrier module of a single-phase electric energy meter. Background technique [0002] At present, the entire national grid system has strict verification procedures and corresponding equipment and facilities for electric energy meters, but the detection of communication modules is relatively blank, and communication modules have a high probability of failure in actual operation. Therefore, there is an urgent need for a fully automated power carrier module independent detection system with high production capacity, small footprint, and low cost. [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 produc...

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 measurement center modules and full automation requirements, the reasons are as follows: First, the module detection system of the module manufacturer is a part of the supporting system for module production, and its detection speed is limited by the module production cycle. The efficiency is low; secondly, when producing different products, it is necessary to manually change the line along with the module production line, and the time cost is high; thirdly, the detection system, as a part of the whole module production system, cannot be well compatible with the module storage system , requires manual intervention, and the labor cost is high; fourth, the module production and testing process requires multiple replacement of the carrier, and the time cycle is increased; fifth, the badly detected modules are piled up in the buffer area, requiring manual intervention for collection
