System and method for realizing multi-source heterogeneous data access by universal equipment gateway

The invention provides a system for realizing multi-source heterogeneous data access by a universal equipment gateway and a message uplink and instruction downlink method based on the system. By means of a general equipment gateway system, multiple types and multiple protocols of Internet of Things equipment are configured and preprocessed, and multiple data protocols are converted into standard unified data formats for a digital platform. The wireless charging device is relatively small in resource occupation and low in power consumption, is suitable for a scene where the electric quantity of a battery is small and frequent charging is inconvenient, can provide reliable connection, and does not cause data loss. 本发明提供了一种通用设备网关实现多源异构数据接入的系统及基于该系统的消息上行和指令下行的方法。其借助通用设备网关系统，将多种类型、多种协议的物联网设备，经过配置与前处理，将多种数据协议转成对数字化平台的标准统一数据格式。其资源占用相对较小，功耗较低，适用于对电池电量很小且不便于频繁充电的场景，同时可提供可靠的连接，不会导致数据丢失。
