Research on the Method of Improving the Collection Efficiency of Platform Curves Based on HPLC Technology

Inhalt:
Currently, the traditional meter reading scheme based on high-speed power line communication (HPLC) technology can only collect electric meter frozen data for 15 minutes at the fastest, which can not meet the requirements of minute level data required by the power Internet of things. To realize the minute-level real-time data acquisition, passage puts forward three improvements to the traditional scheme: Firstly, the acquisition task module is added to the application layer of the station (STA), so that the STA can store the real-time data of the electricity meter and upload it according to the acquisition task; Secondly,the communication between the concentrator and central coordinator (CCO) module is replaced by Ethernet communication, and CCO application layer transceiver sub-layer module is added to overcome the transmission speed bottleneck;Finally, the communication protocol specification from the master station to the station is united. Experimental results show that the new collect efficiency optimization scheme proposed can collect 5-minute frozen data in the field station area, and the upload time is maintained within 70 seconds. More power data can be obtained in the same period of time, which established a data foundation for the business development of ubiquitous power Internet of things.
