DS18B20 uses a line communication interface. Because the first line communication interface, must be completed prior to ROM settings, otherwise the memory and control functions will not be used. Mainly provide one of the following function commands: 1) read ROM, 2) ROM match, 3) search ROM, 4) skip ROM, 5) alarm check. These instructions in no 64 lithography ROM sequence number one device, can at the same time hanging on a line to a plurality of devices choosing a single device, can bus bus hang know how much, what kind of equipment.
If the instruction successfully completes the DS18B20 temperature measurement, the data is stored in the DS18B20 memory. A control function command indicating the performance of DS18B20 thermometry. Measurement results will be placed in the DS18B20 memory, and can read the command issued memory function, read the contents of the on-chip memory. Temperature alarm triggers TH and TL have a byte EEPROM data. If DS18B20 does not use alarm check instructions, these registers can be used as general user memory purposes. The on-chip also contains configuration bytes to ideally address the temperature digital conversion. Write TH, TL instructions, and configuration bytes using a memory function command complete. Through the reading buffer register. Read and write all data from the lowest point.
TFT is the "Thin Film Transistor" referred to as the general film liquid crystal display, but in fact it refers to the thin film transistor that matrix can take the initiative to control the screen independent pixels. The principle of imaging is that the display is made up of many pixels can emit any color light points, by controlling the color of each pixel can display a variety of text and its pictures. In order to accurately control the color and brightness of each pixel, it is necessary to install a "shutter" switch behind each pixel. The TFT LCD backlight is white, white is a mixture of various colors. The white light source also CCFL (Cold Cathode Fluorescent Lamp cold cathode fluorescent lamp), and LED (Light Emitting Diode light emitting diode) light source, in contrast, LED backlight has more advantages. Control so many switches need specialized LCD control chip to control, the use of the LCD control chip model is ili9328.
The final design function is: collecting five temperature sensor temperature, through the STM32 to send the time to communicate with the DS18B20 to obtain the temperature value, the temperature value is stored to the MCU after operation, converted by TFT color LCD display, and has the chip temperature error detection function, when the temperature of the chip not connected when the system will trigger that can connect the sensor after normal operation. Through this graduation design, I not only learn knowledge, but also to find information on the solemn understand many extracurricular knowledge, broaden their horizons, make themselves have great progress in other aspects of professional or professional. However, due to my limited level, there are many inadequacies in the design, these deficiencies will be my future research direction.
The design of the use of single-chip technology, LCD display technology, sensor technology and other scientific knowledge, completed based on single-chip microcomputer control temperature check design. The temperature detection circuit design of the main features of the following aspects:
1 through the monolithic integrated circuit design research, has designed a practical temperature parameter collection, the reading computation and so on.
2 using LCD LCD display technology to complete the temperature and display circuit.
3 external module, when the temperature exceeds the set limit automatically alarm.
4 the whole system software and hardware collocation is reasonable, the system has the speed, the application is flexible, the work is reliable, the operation is simple and so on
After a few months of graduation design, did learn a lot of things, but also deeply aware of their lack of knowledge. Although about to graduate, but in the future work of learning, we must continue to insist on learning new professional knowledge and related non professional knowledge, the only way to keep up with the trend of the times. Believe that the system will be able to get a strong popularity and promotion, for our living to create a better living environment.

基于单片机的温度采集系统设计

 
人们生活和温度是离不开的,它们只有在适宜的环境下,在适宜的温度下,才能更加舒适,我们才能获取更大的愉悦.。实时知道温度的具体变化,什么样的环境下比较适宜,做好温度的防范工作其核心是如何准确地实时地获取温度的数据。必要的时候做出相应的决定,我们才能免除不必要的损失。
随着时代信息科学技术的飞快发展,温度检测在工业、农业及人们的社会生活中扮演着一个越来越重要的角色。在生产及生活的大部分地方需要对环境的温度、物体的温度等进行检测,当温度超过某一定的范围时,过高时需要自动或人为散热,过低时要进行加热,以此来的调节温度,以达到生产和生活的需要。温度传感器经历了三个阶段:传统的分立式温度传感器、模拟集成温度传感器、智能集成温度传感器。当前的称数字温度传感器在20世纪问世的,它是微电子技术、计算机技术和自动测试技术的研究成果,特点是能输出温度数据及相关的温度控制量,通过各种微控制器(MCU)。社会的发展要求人们对传感器的要求也越来越高,现在的温度传感器正在基于单片机的基础上从模拟式向数字式,从集成化向智能化。温度传感器可以感知环境的温度,并且将感知的环境温度通过显示电路将其显示出来,它对人们的生活具有很大的影响,所以温度采集控制系统的设计与研究有十分重要的意义。【转载请注明出处:https://www.5ubs.com/bsTemplate/fanyi/523.html
