Abstract

The present invention provides a multi-point real-time collection system for environmental data, including: a host computer and one or more lower computers distributed in different areas, each lower computer includes a micro-control unit and a plurality of monitors deployed at different monitoring points in the corresponding area Sensor; the sensor is used to collect the environmental data of the monitoring point; the micro-control unit is used to obtain the environmental data of each monitoring point in real time; judge whether the current environmental data of each monitoring point obtained in real time has changed drastically, and will The current environmental data and the identity information of corresponding monitoring points are transmitted to the upper computer; the upper computer is used to receive the environmental data and the identity information of corresponding monitoring points sent by each lower computer in real time, and for any monitoring point, if the upper computer does not When the new data of the monitoring point is received, the current environmental data of the monitoring point is by default consistent with the data received last time. The invention can improve the real-time performance of environment data summarization and tracking with lower overhead.

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...
