According to single slab the design of system of the environment monitor of the machine PIC16 F877
Abstract
With the national attention on the problem of environmental pollution and the improving public awareness of environmental protection, either control or prevention of environmental pollution and environmental degradation, nor improve the environment quality, and other various aspects, environmental protection is very important.
The status of the domestic and international environmental monitoring are analyzed, a new smart environmental monitoring system are developed. It is PIC16F877 microcontroller as the core, the operating parameters of the environment are collected and showed, and achieves alarm functions. The new low-power micro-sensors are collocated to achieve collection of the parameters which include temperature, humidity, light, the concentration of harmful gases, and other parameters, and then the functions about processing, storage, and communications are achieved. It focuses on the hardware and software processes of environmental monitoring intelligent monitoring system. It is specifically analyzed in hardware part that the selection of a variety of sensors, analog processing circuit, microcontroller and external circuit, show circuit and communications interface circuits. On the software part, it's about those software algorithms of the environment intelligent monitoring system, including the main program flow charts, data collection, and keyboard scan, the procedure design for sensor, display, and PC communications. As the poor working environment, various kinds of interference are existing. So the anti-jamming measures are advanced to enhance the ability of the environment monitoring system, taking measures mainly from two aspects of hardware and software.
This system will provide accurate and reliable environment monitoring data. It's timely, accurate and systematic that collection, gather environmental data, and achieving real-time monitoring environment at large areas.
