On-site carrier signal intensity debug method of power system

Abstract

The invention discloses an on-site carrier signal intensity debug method of a power system. The on-site carrier signal intensity debug method of the power system comprises an upper computer and a plurality of handsets. Each handset comprises an OFDM encoding / decoding module. The upper computer comprises a link module, a receiving signal intensity measuring module, a link management module and a touch control panel, wherein the link module is used for downloading a downlink data set DLF from the OFDM encoding / decoding modules or uploading an uplink data set ULF to the OFDM encoding / decoding modules; the receiving signal intensity measuring module is used for measuring the receiving signal intensity value RS1 of the downlink data set DLF; the link management module is used for generating modulation encoding data according to the downlink data set DLF and the receiving signal intensity value RS1; the touch control panel is used for manually sensing the waveform signal intensity value of carrier signals obtained for adjustment in a touch control mode for a user. The on-site carrier signal intensity debug method of the power system can be carried by a power management department or a test department and has the expansibility with multiple interfaces, multiple power information handsets can be pulled out to be used by maintenance personnel on site, carrier signal data are analyzed quantitatively and qualitatively, and debugging is convenient.

Description

technical field [0001] The invention relates to a power system monitoring technology, in particular to a debugging device for field testing the strength of a carrier communication signal at a user site in a power station area. Background technique [0002] 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 During the commissioning 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, there may be no Practical problems such as signal or wiring difficulties, and the need for different testers to work in sections, so the technical problems are highlighted: first, the test process is...

Problems solved by technology

[0002] 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 During the commissioning 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, there may be no Practical problems such as signal or wiring difficulties, and the need for different testers to work in sections, so the technical problems are highlighted: first, the test process is not repeatable, and the test operation needs to be repeated in different environments, relying entirely on the field experience of the testers; Secondly, the labor cost and test cost are relatively large, and it is not convenient to use; moreover, the tester cannot control the specific transmission / reception strength of the carrier signal, which will cause the tester to try repeatedly, time-consuming, and the 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

[0003] 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
