当今社会，在工业和农业逐步完善，人口数量逐年上升的趋势下，有限的水资源

当今社会，在工业和农业逐步完善，人口数量逐年上升的趋势下，有限的水资源越来越匮乏。地下水变得十分珍贵，人们也愈加珍视和保护。因此地下水监测系统逐渐发展完善起来。
该论文采用的是STC89C52单片机，这个芯片拥有8K的存储空间，其工作的最高时钟频率达到32MHZ ，具备高速、低功耗的特点，功能强大且易于学习。利用它来实现对地下水水位、水温、溶解氧和电导率等参数的监测，通过远程通信MAX3232来对各项参数进行实时监测， 并运用MATLAB仿真PID算法，对电机进行控制进而控制地下水水位。 
论文首先阐述了地下水监测系统的前景与状况，接着阐述了该课题的设计构想，以及各个模块电路图及工作原理，最后对课题设计进行总结。

In today's society, in the industrial and agricultural improvement, under the increasing trend in the number of population, limited water resources are increasingly scarce. Groundwater has become very rare, people are increasingly valued and protected. Groundwater monitoring system is developed.The paper is STC89C52 single-chip, this chip has a 8K of storage space, which reached a maximum clock frequency of 32MHZ, with high-speed, low-power features, powerful and easy to learn. Groundwater level, using it to water temperature, dissolved oxygen and monitoring of parameters such as conductivity, MAX3232 through remote communication for real-time monitoring of the parameters, and using MATLAB simulation of PID algorithm to control the motor and control groundwater levels.First expounded the prospects and conditions of groundwater monitoring system, then discusses the design of the subject, and how each module circuit and works, and finally to sum up the project design.Keyword STC89C52 groundwater MAX3232 PID

In today's society, in the gradual improvement of industry and agriculture, the number of population is increasing year by year, the limited water resources are becoming increasingly scarce. Groundwater has become very valuable, people also more cherish and protect. So the groundwater monitoring system is gradually developed and perfected.
the STC89C52 SCM, this chip has 8K bytes of storage space, and the maximum clock frequency to 32mhz, with the characteristics of high speed, low power consumption, powerful and easy to learn. Using it to achieve the monitoring of groundwater level, water temperature, dissolved oxygen and electrical conductivity, etc., through the remote communication MAX3232 to the parameters of real-time monitoring,And using MATLAB algorithm PID simulation, control and control of groundwater level of motor.

first elaborated the prospect and current situation of the groundwater monitoring system, then expounds the design idea of the subject, and each module of the circuit diagram and working principle of, and finally to the topic design were summarized in this paper. Keywords groundwater STC89C52 MAX3232 PID.
