10、scope has never needed to provide for use the power diagraph temperature scope for the 3.0-5.5 Vs BE-55 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 nu

11、mber formats for 912 temperatures biggest be worth to 750 a milli- of second the customer can define of 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 an

12、y hot sensitive systemThe number thermometer that describes the DS18B20 provides 9-12（the programmable equipments temperature read a number. The information is disheveled hair to send to connect through a line from the DS18B20, so central microprocessor and DS18B20 only have a per line conjunction.

13、For read and write and the temperature conversion can acquire energy from the data line, dont need to circumscribe the power. Because each DS18B20 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

14、 machine to place in many different places. Its use is a lot of, include an air condition environment control, detect equipments inside the building or machine, and carry on process monitor and control.The DS18B20 internal structure mainly constitutes to from the four-part cent: 64 temperatures that

15、 only engrave ROM and temperature to spread a feeling machine and dont vaporize report to the police to 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 p

16、ower supply, and at low electricity even period for film power supply until next Gao Dian Pings arrival refreshes .The power of the DS18B20 can also.5V electric voltages get from 3 Vs-5s in the exterior.The DS18B20 adopts front line correspondence to connect. Because the front line correspondence co

17、nnects, have to previously complete ROM enactment, otherwise memory and control function will can not use. Mainly provide following function to order any first of a:1） read ROM2） ROM match3） search ROM4） jump ROM5） report to the police a check.These instruction operation the function has no 64 seque

18、nces that only engrave ROM of a spare part, can be hanging several spare parts on the front line to make selection a certain spare part, at the same time, the total line can also know always on-line hang how much, what kind of equipments.If the instruction successfully makes the DS18B20 completion t

19、emperature measure, the data saves in the saving machine of DS18B20.The performance of a control function conductor designation DS18B20 measures. Measure result will be placed in the DS18B20 memories, and can let reading to send out the conductor of remembering the function, reading contents of slic

20、e ascend saving machine. The temperature reports to the police to trigger machine TH and TLs to all have one word stanza EEPROM data. If DS18B20 not the use report to the police to check instruction, these deposit a machine to be a general customer to remember use. Still carry to there is allocation

21、 words the stanza converting by ideal solution temperature number on the slice. Write TH, TL instruction and allocation word stanza makes use of instruction completion that remembers function. Pass to slowly save a machine to read to deposit a machine. All datas read writing all a beginning from the

22、 lowest.The DS18B20 has 4 main data parts:1、only engrave 64 sequences in ROM are what factory front be only engraved likes, it can see make the address sequence that is the DS18B20 code.64 alignments that only engrave ROM are: Starting 8（28 Hs） is the product type mark number, immediately after of 4

23、8 sequences that is the DS18 B20 oneself, last 8 is 56 front circulating redundancy schools to check code.（CRC=X 8+ Xs 5+ Xs 4+s 1）The function that only engraves ROM is to make each DS18B20 all each not same, so can carry out a purpose that is always on-line to hang to connect several DS18 B20s.2、t

24、he temperature in the DS18B20 spread a feeling machine to complete the diagraph to the temperature and take 12 conversions as an example: The binary system expanding with 16 signs repairs code to read to count a form to provide, with 0.0625 |the LSB form express, among them, the S is a sign.The savi

25、ng machine of DS18B20 includes high speed to temporary save machine RAM and can give or get an electric shock to wipe in addition to RAM, can give or get an electric shock to wipe in addition to RAM includes temperature to trigger machine TH and TL again, and an allocation deposits a machine. Saving

26、 machine ability the integrity really settle the communication of front-line port, the number starts using to write the order of depositing the machine to write into deposit a machine, immediately after can also use order of reading to deposit the machine to confirm these numbers. After confirming c

27、an use the order that the replication deposits a machine can give or get an electric shock to wipe to transfer these numbers to in addition to RAM in. While once modifying to deposit the number in the machine, this process can ensure the integrity of number.The high speed temporary saves machine RAM

28、 to constitute to from the saving machine of 8 word stanzas; The first and the second word stanza are temperatures to show. The fourth Sha-ho word stanza is to make duplicate TH and TL, at the same time the fourth Sha-ho number of word stanza can renew; The fifth word stanza is to make duplicate all

29、ocation to deposit a machine, the fifth number of word stanza can renew at the same time;6, 7, 8, three word stanzas are calculator oneself use. Using reads that the order that deposit a machine can read the ninth word stanza, this word stanza is eight word stanzas to the front to carry on schools t

30、o check.64 8 ex- oneself codes that is a DS18B20 that only engrave ROM, next 48 are a continuous number code, 8 of end is to 56 ex- of the CRC schools check.64-the light of engrave ROM and include the function order of 5 ROMs:Read ROM, match ROM, jump up ROM, check to seek ROM and report to the police to check to seek.The DS18B20 can use external powe
