AI Technical Summary
Technical Problem
Existing AMI systems suffer from high latency, concentrated network traffic, and heavy server load when collecting load curve data, making it impossible to achieve near real-time monitoring and efficient data collection.
Method used
The system establishes a connection with the electricity meter via the ANSI C12.18 protocol, reads configuration parameters, triggers data collection tasks at preset push cycles, calculates storage size and offset, and actively pushes load curve data. The data is then sent to the AMI system master station using DLMS, MQTT, or CoAP protocols.
Benefits of technology
It enables proactive and near real-time acquisition of load curve data, reduces network traffic concentration, lowers server load, and improves data timeliness and system efficiency.

Abstract
本发明适用于智能电网技术领域，涉及一种负荷曲线数据采集与推送方法及系统，包括：通信模块通过ANSI C12.18协议连接电表，读取Table 61配置参数并计算Block存储大小；按预设推送周期定时触发采集任务，读取Table 63获取当前Block状态；根据推送周期与间隔时间计算所需间隔数据条数；若当前Block有效间隔数充足，执行不跨Block读取流程；若不足，则执行跨Block读取流程，分别从上一个Block和当前Block读取数据并组合；将读取的负荷曲线数据封装为推送协议报文，主动发送至AMI系统主站。本发明提升了数据采集的实时性和系统效率。
