City Green Space Ecological Evaluation Factor Collection Monitoring And Evaluation Method Research

With the rapid development of social economy, people’s living standard has been greatly improved, people pay more and more attention to the ecological environment, city ecological environment problems begin to get the attention of the society. At present, our country city ecological environment is not optimistic, industrial pollution is serious, the phenomenon of city haze happens frequently, in order to curb the deteriorating trend of the deterioration of ecological environment, we need to pay more attention to city green space ecological environment and take effective measures to protect it, establish the perfect monitoring system of city green space ecological environment, grasp the city green space ecological environment dynamic change entirely, predicte the development trend, provide regular dynamic monitoring data, and provide accurate data for the city green space ecological environment protection. Therefore, we need to develop a design of low power consumption, low cost, stable and reliable, convenient deployment of wireless sensor networks.This article design a wireless sensor network for city green space ecological environment monitoring based on the ZigBee technology, which introduces the hardware and software design of city green space ecological environment monitoring node of wireless sensor network. The node using80C51MCU and CC2530+CC25912.4G RF chip ultra low power, and transplanted ZigBee2007PRO protocol stack, can real-time collect the data of surrounding environment in sunlight, temperature, humidity, atmosphere and soil. The node transmits the data collected to the host computer by wireless sensor network. The article introduces the controller module design,the design of data acquisition module, high frequency circuit design, CC2530antenna design, the power supply module design, and the reset circuit design in hardware, also introduces the design of data acquisition program, the design of CC2530wireless communication program, Z-Stack transplantation plate, as well as the development of the city green space ecological environment monitoring. Finally, an evaluation of the environmental monitoring algorithm is designed, and the system is tested.
