摘要
随着现代电子科技和信息技术的高速发展,具有温度检测和控制功能的智能装备已被广泛应用于诸多领域。目前,在很多室内休闲场所,为了保持舒适的环境温度,常需采用温度测试装置来调节室内的温度。同时跨区域和跨季节的植物养殖栽培,也需要对温度等参数进行监测,由于各种植物适宜生长的温度不同,就需要采用温度检测控制系统,调节植物生长所需要的温度,从而保证植物生长的有效环境。
通过对89S52单片机进行编程,从而控制DS18B20进行温度测量和温度转换。从而实现温度范围在0℃~40℃可调,具有报警、降温、升温等功能,掉电不丢失数据的功能。
该系统采用模拟方案,采用发光二极管和蜂鸣器分别模拟执行降温和升温控制点设备,用发光二极管模拟降温控制设备——空调,用蜂鸣器模拟升温控制设备——加热器。带系统调试完毕后,再去控制实际执行设备。

Abstract
With modern electronic technology and the rapid development of information technology, with the temperature sensing and control capabilities of smart equipment has been widely used in many fields. Nowadays, in many indoor leisure places, in order to maintain fortable temperature, It usually requires the use of temperature measurement device to adjust the indoor temperature. Both inter-regional and cross-breeding season plant cultivation, temperature and other parameters need to be monitored. Because of A variety of different temperature suitable for the growth of plant, on the need for temperature measurement and control systems, plant growth regulating the temperature required to ensure the effective plant growth environment.
By 89S52 microcontroller is programmed to control DS18B20 temperature measurement and temperature conversions. In order to achieve a temperature range of 0 ℃~ 40 ℃ adjustable, with alarm, cooling, heating and other functions, non-volatile data.
The system uses analog solution, Using light-emitting diodes and buzzer warming and cooling were simulated execution control point device, light-emitting diodes simulated annealing control equipment - air conditioning, heating control equipment with analog buzzer - heaters. With the system, after debugging, go to the actual implementation of the control device.
