Abstract

The invention discloses a real-time environment monitoring system based on a fully dispersed mode, and belongs to the technical field of environment monitoring systems. Comprising a plurality of data processing terminals and sensors, and each data processing terminal independently analyzes and processes respective data. And each sensor and the data processing terminal adopt a loose connection structure in space, and a wireless channel is used as a mutual interaction channel. Under the constraint of real-time requirements, a wireless broadcast mechanism is adopted to complete data distribution, and under the action of the broadcast mechanism, each data processing terminal receives sensing data of each sensor at the same time. By receiving the broadcast data, the time delay of data forwarding is avoided, and the consistency of the data at different processing terminals is ensured. A time division multiple access mechanism is established on the 433Mhz wireless technology, a weighted average data anti-loss mechanism is adopted to reduce the channel transmission loss rate, and the problems that an environment monitoring system is not high in real-time performance and data is prone to being lost are solved.

Embodiment Construction

[0014] In order to describe the technical solutions of the present invention more clearly, the present invention will be further described below with reference to the accompanying drawings and implementation principles.

[0015] A real-time environmental monitoring system based on a fully decentralized mode adopts a network structure of a real-time environmental monitoring system. One data processing terminal collects the data of one sensor, and each data processing terminal independently completes the analysis and processing of its own data. as attached figure 1 As shown, using the 433Mhz wireless time division broadcasting network, sensor 1 corresponds to data processing terminal 1, that is, sensor n corresponds to data processing terminal n, and n is the number label of the sensor.

[0016] The specific implementation method of the 433Mhz wireless time-division broadcast network is as follows: In order to ensure the real-time transmission of sensor data on the 433Mhz channe...
