1、1学生毕业设计(论文)外文译文学生毕业设计(论文)外文译文译文标题(中英文):DS18B20 芯片资料 ADC0832 资料译文出处: 器件数据手册指导教师审阅签名签名: The DS-18B20 number temperature spreads a feeling machineThe DS-18B20 number temperature spreads a feeling machine, the product adoptions United States DALLAS company produces of DS18 B20 can set net number the tem

2、perature spread the feeling machine chip to pack but become and have to bear to whet to bear to touch, the physical volume is small, use convenience, seal to pack a form diverse, be applicable to various narrow and small space equipments number to measure moderate control realm.1、the technique funct

3、ion describe:1.1 special single lines connect a peoples method, DS18 B20 while linking with microprocessor only need a line can immediately carry out the double of microprocessor and DS18 B20 toward the communication.1.2 measure scope-55 +125 , proper measure resolutions 0.5 .1.3 support several set

4、 nets function, several DS18 B20s can merge at unique three on-line, the most can merge 8, if amount was excessive, it would make power supply the power electric voltage over low, result in thus the signal delivers of unsteady, the realizations order to measure more1.4 work the power:35V|DC1.5 dont

5、need any outer circle component in the use1.6 measure the result measure a way string with 912 numbers line transmission1.7 stainless steels protect to take care of diameter 61.8 be applicable to DN1525, DN 40 DN250 various equipments that lie industrial piping of quality and narrow and small space

6、measure1.9 standards install the thread M10 X1, M12 X1.5, the G 1|2 term chooses1.10 PVC electric cable direct the line or virtuous type ball type connect line box line, the easy to and other electric appliances equipments links.2、Application22.1 products are applicable to cold storage, food Cang, k

7、eep a bottle, tele-communications engine room, electric power engine room, cable slot etc. measures moderate control realm2.2 stalk tiles, urn body, the Fang machine, the air condition, waits industrial equipments of narrow and small space to measure a moderate control.2.3 car air condition, refrige

8、rator, cold cabinet, and medium low temperature dry box of etc.s.2.4 provide hot|make cold piping calories to calculate, the central air condition divides a thermal energy to calculate to measure a moderate control with industrial realm3、Product model number and specificationThe model number measure

9、s scope to install thread electric cable length to apply pipingThe B20 -55125s TS-18s have no 1.5 msTS-18B20A -55125 M10X1 1.5m DN1525The B20 TS-181|s Bs-55125ses 2 Gs connects line box DN40 604、Connect line elucidationThe characteristics special front line connects, needs a line to correspond by le

10、tter to order more ability and simplified a distribute type the temperature spread the feeling application didnt need an external component to use data total line power supply, the electric voltage scope has never needed to provide for use the power diagraph temperature scope for the 3.0-5.5 Vs BE-5

11、5 to+125 .The Fahrenheit is equal hence-67-257 Fahrenheit degree-10 go to+85 accuracy inside the scope is 0.5 The temperature spreads a feeling machines programmable resolution to convert into 12 number formats for 912 temperatures biggest be worth to 750 a milli- of second the customer can define o

12、f not and easily lose sex temperature to report to the police to establish an application to include a constant temperature control, industrial system, consume electronics product thermometer, or any hot sensitive systemThe number thermometer that describes the DS18 B20 provides 9-12(the programmabl

13、e equipments temperature read a number.The information is disheveled hair to send to|connect through a line from the DS18 B20, so central microprocessor and DS18 B20 only have a per line conjunction.For read 3and write and the temperature conversion can acquire energy from the data line, dont need t

14、o circumscribe the power.Because each DS18 B20 includes a special ordinal number, several ds 18 bs 20 seses can be existed to a total line at the same time.This makes the temperature spread a feeling machine to place in many different places.Its use is a lot of, include an air condition environment

15、control, detect equipments inside the building or machine, and carry on process monitor and control.The DS18 B20 internal structure mainly constitutes tofrom the four-part cent:64 temperatures that only engrave ROM and temperature to spread a feeling machine and dont vaporize report to the police to

16、 trigger a machine TH and TL and allocation to deposit a machine.While equiping signal line Gao, the internal capacitor stores an energy from a line and corresponds by letter circuit to the film power supply, and at low electricity even period for film power supply until next Gao Dian Pings arrival re- refreshes.The power of the DS18 B20 can also.5V electric voltages get from 3 Vs-5s in the exterior.The DS18 B20 adopts front line correspondence
