【摘要】：随着全球气候的变化,现在各国的气候环境受到很大的影响,其中气候特别是温湿度对森林植被的生长,动物的栖息与繁衍带来很大的影响。为了更加清楚的了解研究野外环境温湿度的常年状况,需要一个便宜、便携、可靠、能够长期值守并有效的实时数据采集系统来进行实时的监测。本论文主要内容是使用PC个人电脑通过GPRS数据传输方式来远程控制终端下位机MCU进行温湿度数据采集的一种野外信息检测记录系统。系统采用PIC单片机来控制温湿度传感器按设置的采样间隔进行数据采集,也可以选择手动在PC电脑旁点击数据中心控制界面相应的按钮进行采集,通过GPRS把采集的数据发送至PC机,同时PIC单片机将采集到的数据存储到SD卡中方便后续分析研究,是实现低能耗的电池供电模式的一种数据采集系统。本系统的下位机选用的是PIC单片机,具有开发容易、周期短,程序执行速度快,低功耗,性价比高等特性。单片机连接DS18B20智能数字温度传感器和相对湿度传感器HIH3610,加上数据存储SD卡构成整个系统的数据采集终端,能够自行实现数据的长期海量存储温湿度数据的功能。单片机通过RS-232与GPRS模块连接,通过GPRS无线网络与Internet因特网实现野外信息的远程控制,在PC个人电脑上用VC建立的软件界面里显示其对应的图形数据,实现野外信息的远程监视与显示。从而使得整个系统实现了基于单片机的野外信息检测记录系统的设计。由于GPRS具有传输速率高、接入时间短、提供实时在线功能、按流量多少来计费等性能特点。综合PIC单片机的功能特性以及采集模块的低功耗性使得整个系统特点是造价便宜、携带方便、工作可靠、能够长期值守的一种微型微功耗远程控制系统。
[Abstract]:With the change of global climate, the climate environment of different countries has been greatly affected, especially the climate, especially the temperature and humidity, to the growth of forest vegetation. The habitat and reproduction of animals have a great impact. In order to better understand the perennial conditions of temperature and humidity in the wild, we need a cheap, portable and reliable environment. Can be on-duty and effective real-time data acquisition system for real-time monitoring. The main content of this paper is to use PC personal computer through GPRS data transmission mode to remotely control the terminal lower computer MCU for temperature and humidity data acquisition system. The system uses PIC single chip computer to control the temperature and humidity data acquisition. The temperature and humidity sensor carries on the data acquisition according to the set sampling interval, It is also possible to manually click on the corresponding button of the data center control interface next to the PC to collect the data and send the collected data to the PC through GPRS. At the same time, the PIC microcontroller can store the collected data in the SD card for further analysis and research. It is a kind of data acquisition system to realize low energy consumption battery power supply mode. The lower computer of this system is PIC singlechip, which has the advantages of easy development, short cycle, fast program execution and low power consumption. The MCU connects DS18B20 intelligent digital temperature sensor and relative humidity sensor HIH3610, and the data storage SD card constitutes the data acquisition terminal of the whole system. The single-chip computer can connect with GPRS module through RS-232, and realize remote control of field information through GPRS wireless network and Internet Internet. The corresponding graphic data are displayed in the software interface set up by VC on PC personal computer, and the remote monitoring and displaying of field information are realized, which makes the whole system realize the design of field information detecting and recording system based on single chip microcomputer. Because GPRS has the characteristics of high transmission rate, short access time, real-time on-line function, and charging according to the flow rate, the characteristics of PIC MCU and the low power consumption of the acquisition module make the whole system cost cheap. A micro micro-power remote control system which is easy to carry, reliable and on duty for a long time.
