Data concentrator with class-D voltage quality monitoring function

Abstract

The invention discloses a data concentrator with a class-D voltage quality monitoring function. The data concentrator comprises a power module and a processing module, the power module is in electric signal connection with the processing module, an input end of the processing module is connected with a signal output end of a GPRS (general packet radio service) / CDMA (code division multiple access) module or a 0 / 100Base T Ethernet module, signal output or input ends of a display module, a key module, an alternating-current sampling module, an infrared module and a remote signaling module are respectively connected with a signal input or output end of the processing module, and signal output or input ends of an RS485 interface module and a maintenance RS485 interface module are connected with the signal input or output end of the processing module. The data concentrator has functions of an existing data concentrator and a 220V-line voltage monitor monitoring function and achieves class-D voltage monitoring point distribution, so that a great quantity of investment for power supply enterprises to purchase voltage monitors is saved while maintenance and use are facilitated for users.

Description

technical field [0001] The invention relates to a data concentrator with a class D voltage quality monitoring function. Background technique [0002] Since May 2009, the State Grid Corporation of China has invested more than 100 billion yuan each year in the construction of a "strong and smart grid". As an important part of the smart grid advanced measurement system AMI, the power user information collection system (abbreviation: power consumption information collection system) realizes informatization, automation, and interaction for the technology of the smart grid, and realizes collectivization, Intensification, leanness, and standardization play a vital role. Since 2010, the annual bidding capital of Wangjia Grid Company has reached several billion to tens of billions of yuan. The concentrator is the key equipment for data upload and release in the power consumption information collection system, and each station area in the system must be equipped with at least one. ...
