A portable meter box rs485 wiring quick detection device and method

Abstract

The invention discloses a rapid detection device and a detection method for the RS485 connection of a portable electric meter box. The device comprises a CPU processor. The CPU processor is respectively connected with a receiving / transmitting circuit, a gain control circuit, a voltage detection circuit, a control circuit and a flash disk data storage module. The receiving / transmitting circuit is respectively connected with a Symbol SE 900-series laser scanning engine and a liquid crystal display module. The gain control circuit is respectively connected with a key circuit and a clock circuit. The key circuit is connected with a keyboard operation system. The clock circuit is connected with an OSC oscillator. The voltage detection circuit is connected with a power supply circuit and a high-brightness flashlight. The control circuit is respectively connected with a serial port data conversion circuit and a buzzer. The flash disk data storage module is connected with a printing circuit. In this way, the point-to-point fast and automatic detection from an II-type concentrator to each electric energy meter is realized, and the wiring quality of an RS485 bus at a detection site is detected. The on-site meter-reading rate is improved. After the detection process, a detection report is formed to be exported or printed.

Description

Technical field: [0001] The invention relates to a portable electric meter box RS485 connection rapid detection device and method, which are widely used in the field of electric power industry equipment and belong to the technical field of electric power measurement. Background technique: [0002] As a client-end intelligent measurement method, the electricity consumption information collection system is the basis for the State Grid Corporation of China to realize lean, standardized, and intensive management in its marketing management. Making full use of the power consumption information collection and management function is the premise and technology for a complete change in the marketing management method Support is also an important support for the company to promote the "two transformations", implement the "three sets and five majors", strengthen lean management, improve quality service levels, and expand the power market. [0003] "Full coverage, full collection, and f...

Problems solved by technology

[0004] 1. If the equipment does not work normally and the cable connection is not correct, it will directly affect the meter reading rate after it is put into operation, and rework will bring about an increase in labor costs

[0005] 2. The operation and maintenance work in some provinces is also entrusted to a third party. During the acceptance inspection, there is no effective detection method for the quality and accuracy of the installation, which leads to repeated construction and low rate of meter reading on site.
