1、 数据接入与转发功能：1. Data access and forwarding functions:

（1）标准化数据通讯代理:接入不同厂商、不同通信接口的在线监测装置，统一转换为DL/T 860与站端监测单元通信。(1) Standardized data communication agent: access to online monitoring devices of different manufacturers and different communication interfaces, and uniformly convert to DL/T 860 to communicate with the station monitoring unit.

Task scheduling refers to selecting a task in the task queue according to certain criteria and executing the task. Each task item can be conveniently loaded into the scheduled task scheduling service as long as it conforms to the interface specification stipulated by the scheduled task scheduling service system. The timing task scheduling service system provides a flexible scheduling mechanism, a unified logging mechanism and a task execution tracking mechanism, so different task component items only need to complete their own independent business requirements, and do not need to care about the task scheduling mechanism. The scheduled task scheduling service system can be applied to manage and schedule system function requirements that are executed periodically or once at a specified time. By using the scheduled task scheduling service system, the execution cycle of background tasks can be managed, the execution of background tasks can be scheduled, and the execution process of background tasks can be monitored.
