A carrier-type power acquisition device and its carrier test device

Abstract

The invention discloses a carrier wave type power collection device, which comprises a body composed of a power collection module and a data integration module plugged in with each other. The metering circuit obtains and calculates the power signal; the data integration module obtains the calculated power signal through the MCU for data processing, stores it through its first rewritable memory, and performs carrier data communication through the built-in carrier module ; Among them, electrical pins are provided on the side of the power collection module, and electrical slots are provided on the side of the data integration module to realize plug-in combination. The invention can be applied to the data acquisition equipment in the grid power system. The invention also discloses a matching carrier signal testing device, which can be used portablely by inspectors, and can simulate the grid condition in the station area to test the carrier performance of the electric measuring device.

Description

technical field [0001] The invention relates to an intelligent centralized meter reading technology, and more particularly, the invention relates to a carrier-type single-phase electrical measuring equipment and its supporting testing equipment. Background technique [0002] Automatic meter reading system (AMR) refers to a system in which the remote master station server reads the electric energy recorded value data of the electric energy meter in the station area through transmission media (such as wireless, wired, power line carrier (PLC), etc.). It consists of electric energy meter, collector, concentrator and remote master server. The concentrator is an intermediate part of the AMR system. It communicates with the master station through the data channel, completes the master station's instructions, automatically completes meter reading and records data, and transmits it to the master station according to the rules specified by the master station. As the scale and comple...

Problems solved by technology

[0003] When the power management department or power product manufacturer reads or tests the power grid monitoring and metering equipment, it mainly relies on the tester to use the handheld device to perform wireless data acquisition in a certain preset area in the station area, or In the debugging process, for example, a twisted-pair cable several hundred meters long is laid in a building, and it is connected to the power line in the building for carrier meter reading. However, due to problems such as signal strength, it may occur when replacing another building. There are no practical problems such as signal or wiring difficulties, and different testers need to work in sections, so the technical problems are highlighted: first, the test process is not repeatable, and the test operation needs to be performed again in different environments, completely relying on the testers' field experience ; secondly, labor costs and test costs are large, and it is not convenient to use; furthermore, testers cannot control the specific transmission / reception strength of the carrier signal, which will cause testers to try repeatedly, time-consuming, and collected The strength of the signal cannot be analyzed qualitatively and quantitatively, but the test results cannot be analyzed, which is not helpful to the test process

[0004] In the prior art, there is no use of portable on-site test devices, and testers carry different types of test instruments, which cannot meet the purpose of data collection and integration

[0005] Furthermore, in the prior art, there is no use of split power collection equipment, that is, the strong current part and the weak current part are isolated from each other and can be disassembled, and the carrier power line method is still commonly used to read its data information
