基于现场适应性策略的自动抄表任务调度算法

针对因关口表自动抄表系统与电量采集终端之间通信连接不可靠等因素造成的计量信息读取不同步的问题，以及不同用户对计量信息读取的需求不同引起的软件系统现场适应性问题，设计一种基于现场适应性策略的自动抄表任务调度算法。在分析用户需求的基础上，采用人机界面供用户按自己的实际需求设置和提交抄表策略，设计一种自适应用户需求、具有优先级的任务调度算法，自动识别用户提交的抄表策略并根据计量信息抄读进度和人工提交的召唤任务，自动生成和调度具有优先级别的任务表，实现自动抄表的目的。工程应用的情况表明，本算法能满足不同用户的需求，能自动和人工追补系统丢失的历史信息，保障计量信息的完整性和可追溯性。

Automatic Meter Reading Task Scheduling Algorithm Based on Site Applicability Strategy

Aiming at the question about billing information reading being out of sync which was caused by the unreliable communication connection between automatic meter reading system and energy remote terminal unit, and the problem on applicability of the products caused by various users’ requirements, an automatic meter reading task scheduling algorithm was developed based on site applicability strategy. Through analyzing users’ requirements, the meter reading strategy man-machine interface was designed to set and submit themselves strategy according to actual ones. A task  cheduling algorithm with priority was developed which can adapt users’ demand. This algorithm could schedule task table with priority to achieve the goal of meter reading which was generated by distinguishing meter reading strategy submitted by users automatically and retrieving calling progress of history information and accepting manual call commands. The engineering application shows that various users’ requirements could be met by this algorithm, integrity and traceability of billing information could be protected by supplementing to call the lost information automatically and manually.
