Data acquisition tool for power grid equipment

Abstract

The invention discloses a data acquisition tool for power grid equipment. The data acquisition tool comprises a data acquisition module, a data processing module, an STM32 single-chip microcomputer, aliquid crystal display module, a W25Q64 external memory and an RS-485 communication module, the data acquisition module acquires analog quantity data signals on a power line. An analog quantity datasignal is transmitted to a processing circuit of the data processing block to be processed; the processed data is input into the STM32 single-chip microcomputer through the RS-485 communication module, the STM32 single-chip microcomputer converts analog quantity signals into digital quantity signals and processes the digital quantity signals, and the processed data is stored in the W25Q64 externalmemory and displayed on the liquid crystal display module of the STM32 single-chip microcomputer. The tool is convenient to carry, and data is very convenient to obtain. An electric power data recording device is formed by relatively mature products which are easy to buy in the market, so that the reliability of the device is improved, the cost is reduced, and the device has relatively high costperformance.

Description

technical field [0001] The invention relates to the technical field of grid equipment operation, maintenance and repair, and in particular to a grid equipment data collection tool. Background technique [0002] Under the irreversible application trend of new technologies such as the Internet, cloud computing, big data and the Internet of Things, the original technology and management models of power grid enterprises have been greatly impacted. Intelligent on-site operation and maintenance and management and control are important areas for the application of new information and communication technologies and the construction of management and control platforms. It is urgent to carry out research on the intelligent system of on-site operations to realize standardized collection of on-site data, standardized guidance for on-site operations, and multi-dimensional real-time analysis of equipment status. Data upload, mutual sharing of data and analysis algorithms between the field...

Problems solved by technology

For a long time, substations have used traditional instrumentation devices to measure main power data such as voltage, current, and frequency. The disadvantage of this method is that if these data are to be recorded, special management personnel are required to record them. shortened, the workload increases, and necessary manpower and material resources are needed to support it, and analyzing these data in the future is also a relatively cumbersome task. With the transformation of the power grid, many substations have carried out comprehensive automation transformation, eliminating this Traditional instrumentation has effectively improved the above problems, but there are still many conventional substations that have not been transformed, and still use this method to measure and record data
