At present, the domestic user sensing equipment taking the non-intervention load identification technology as the core mainly comprises a non-intervention load identification terminal, a multifunctional load identification table, intelligent idle load identification and other product forms. Urban and rural resident interaction demonstration projects taking non-intervention load identification terminals and multifunctional electric meters as main forms are applied to trial points or developed on a large scale in a plurality of provinces and cities in China.
Numerous scholars and research institutions in China have successfully developed the technology in a commercialized manner through research in the last ten years, rely on Jiangsu 863 key special project "urban users and power grid supply and demand friendly interactive system", develop the installation application of non-user terminals in Suzhou and Changzhou areas, and implement the resident demand response demonstration project with the greatest user's regulation in the world. Under the influence of Jiangsu test point effect, other provinces and cities in China are gradually starting to test points of non-invasive technology.
The digital testing system platform of the non-intervention load sensing module directly sends a recording waveform file (meeting the requirements of a Comtrade standard format defined by IEEE and comprising voltage and current information) of the operation of an electric appliance to a corresponding receiving interface of the load sensing module in a digital quantity mode, and independently detects the load sensing module in a mode of collecting a load sensing result.
Based on the load identification detection platform generated under the above scene, the digitized electricity information is transmitted to the MCU development board in the form of a network port mainly through detection software, then the MCU development board is transmitted to a designated identification module through a serial port, and the feedback of the identification module is collected through the MCU and is transmitted to the detection software.
Since MCUs have limited performance (about 5 ms/packet) and only one TCP connection can be maintained, the detection software should control the communication rate with each MCU (about 5 ms/packet) and only establish one TCP long connection, communication with the same MCU can always only use this connection, thus limiting the performance of the overall system.
