Environmental data multi-point real-time collecting system

Abstract

The invention provides an environmental data multi-point real-time collecting system. The environmental data multi-point real-time collecting system comprises an upper computer and one or more lower computers distributed in different areas. Each lower computer comprises a micro control unit and multiple sensors arranged at different monitoring points in the corresponding areas, wherein the sensors are used for collecting the environmental data of the monitoring points, and the micro control unit is used for obtaining the environmental data of the monitoring points in real time. Whether the current environmental data, obtained in real time, of each monitoring point change seriously is judged, and the current environmental data and the identity information of the corresponding monitoring point are transmitted to the upper computer when serious changes happen. The upper computer is used for receiving the current environmental data and the identity information of the corresponding monitoring point transmitted by each lower computer in real time, and for any monitoring point, if the upper computer does not receiving the new data of the monitoring point, it can be confirmed that the current environmental data of the monitoring point are consistent with the data received last time. The environmental data multi-point real-time collecting system can improve the real-time performance of summarization and tracking of the environmental data with low expenses.

Description

technical field [0001] The present invention relates to the technical field of environmental perception, in particular, the present invention relates to a multi-point real-time collection system of environmental data. Background technique [0002] The environmental data multi-point acquisition system can collect sensor data distributed in multiple different locations, and summarize them to the central node, so as to perform one or more types of environmental data (such as temperature data, humidity data, etc.) in a certain area. Monitor for a long time. Due to the long-term operation of the system and the limitation of cost and other factors, it is usually difficult for the current multi-point acquisition system of environmental data to realize real-time data collection and aggregation. Taking temperature acquisition as an example, a typical temperature acquisition system based on the DS18B20 chip includes a host computer and multiple slave computers. The slave computers ar...
