High performance liquid chromatography (HPLC) communication test system based on strong current attenuator

Abstract

The invention discloses an HPLC (High Performance Liquid Chromatography) communication test system based on a strong current attenuator. The HPLC communication test system comprises a power supply module, an isolation module, a metering terminal module, an analysis detection module, a carrier attenuation module and a carrier communication detection module. The power supply module and the isolation module supply power to the test system, the analysis detection module controls the carrier attenuation module to attenuate a carrier signal, and the metering terminal module carries out carrier communication and carries out data interaction with a to-be-detected ammeter of the carrier communication detection module. The analysis and detection module reads test data of the metering terminal module to analyze a test result, and a plurality of levels of carrier attenuation devices arranged by the carrier attenuation module can simultaneously perform attenuation value tests of different levels from small to large in each level. The carrier communication component performance information of the to-be-detected electric meter can be rapidly obtained, meanwhile, the obtaining cost of the failure rate of the component can be reduced, and the carrier module detection efficiency of the test system is effectively improved.

Description

technical field [0001] The invention relates to the technical field of electric power carrier testing, in particular to an HPLC communication test system based on a strong electric attenuator. Background technique [0002] Power Line Carrier (PLC, Power Line Carrier) is a unique communication method for power systems. Power line carrier communication refers to a technology that uses existing power lines to transmit analog or digital signals at high speed by means of carrier waves. The biggest feature is that there is no need to re-set up the network, as long as there are wires, data transmission can be carried out. HPLC is a high-speed power line carrier, also known as a broadband power line carrier, which is a broadband power line carrier technology for data transmission on low-voltage power lines. The broadband power line carrier communication network uses the power line as the communication medium to realize the aggregation, transmission and interaction of low-voltage po...
