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. 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 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 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 power 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 connects, 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 sequences 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 temperature 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 slice 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 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 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 48 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、the 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 saving 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 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 can 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 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 allocation 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 to 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 power VDD as well as use the power in the living on of inner part. When the VDD port connects the electric voltage with 3.0 Vs Vs-5.5ses is use external power; When the VDD port connects ground used the power in the living on of inner part. No matter is an inner part to live on the power or an external power supply, I|the O line want to connect a 5 K to or soly and up pull electric resistance.Allocations depositing a machine is the conversion that installs different number to make sure temperature and number.R1, the R0 is the decision of temperature, from the R1, the different combination of R0 can install for 9, 10, 11, 12 temperatures show. So can know a different temperature conversion to should of conversion time, four kinds of resolutions of allocations distinguish to 0.5 , 0.25 , 0.125 and 0.0625 , factory take installing as 12.DS18B20 at factory with install for 12, read temperature totally read 16, so the empress is 112 enter make to convert into 10 enter make after at multiply 0.0625 is then measure of temperature, also need to be judged plus or minus. Front 5 piece words are signs, current 5 is 1:00, read of temperature is minus quantity;5 is 0:00, read at present of temperature is plus quantity.16 numbers put from low to Gao Wei.The instruction agrees on code operating instructions:1) The temperature converts the 44 H start DS18B20 to carry on a temperature conversion2) Read to temporary save machine BEH to read to temporary save machine 9 word stanza contentses3) Write temporary and save the machine 4 EHs to write in a data temporary TH of saving the machine and TL word stanza4) The replication temporary saves the machine 48 Hs temporary save the TH of machine and TL word stanza to write E2 RAM5) Re- adjust the E2 RAM B8s Hs write the E2 TH within RAMs and TL word stanza to arrive to temporary save machine TH and TL word stanza and read that the signal that the B4 H start DS18B20 of the power supply method sends out the power supply method gives lord CPUThe beginning of DS18B20 starts to turn.1) place data line first Gao Dian Ping1.2) postpone(what the time request isnt very strict, but possibly a little bit shorter)3) the data line pull a low electricity even0.4) postpone 750.(the horary time scope can from 480-960)5) the data line pull Gao Dian Ping1.6) wait for while postponing(if is early to start to become an achievement then in 15-60 time inside produce a low electricity that is returned by the DS18 B20 even0.Can make sure its existence according to the status, but should notice can not be infinitely carry on waiting for, otherwise will make procedure get into to die circulating, so control while wanting to carry on to be super).7) if CPU read the data is on-line low to give or get an electric shock even0 after, while also needing to do to postpone time for it to postpones from send out of Gao Dian Ping start to calculate to at least want 480.8) pull data line again Gao Dao Gao to end after giving or getting an electric shock is even1.As the simple structure, convenient installment, low loss and wide range of temperature test, DS18B20 temperature test sensors are applied to the fields which needs the multipoint temperature test, such as the chemical industry, the grain, the environment supervision and so on. Because of the adoption of one bus in the DS18B20 multipoint temperature test system, all DS18B20 are hung on one bus, and then the temperature conversion value of each test point is read by turns. As the conversion value must be read after reading-pin state for 8 times, and position and store data must be moved, so time spend much in reading one point of the data system by every time. If the temperature test system is large-scaled, the system loss caused by it is rather much, and then the alternate test speed of the system decreases obviously, which influences the efficiency of the multipoint temperature test system seriously. In this paper, DS18B20 are hung on some I/O buses by grouping DS18B20 evenly, and the conversion temperature data is obtained by reading the state of DS18B20, then the system loss decreases and the alternate test speed increases obviously, which wont influence the precision and the reliability of the conversion. A set of multipoint temperature test of artificial environment laboratory is achieved in this paper, which increases the test efficiency of the former system. DS18B20 is the single bus digital temperature sensor from American Dallas Company. DS18B20 is consisted of the 64 figures ROM engraved by laser, the temperature sensitivity component, non-volatile temperature alarms trigger (Device TH and TL).DS18B20 communicates with the microprocessor by the single bus port and the test range of DS18B20 is from -55 centigrade to +125 centigrade, and the incremental value is 0.5 centigrade. The temperature can be changed into figures within 720ms and each DS18B20 has the sole 64 figures serial number. The specific content is revealed as Fig 1: There are two 8 figures storages (No.0 and No.1) for storing temperature value in DS18B20. No.0 storage stores complement of the temperature value, and No.1 stores symbols of the temperature value. The user can define non-volatile temperature alarms sets and distinguish the alarms search order and seek the component temperature alarms state outside the scheduled limit. There are two alternative ways of power supply: Signal bus high-level borrow power is adopted, or the +5v power supply externally is adopted directly.DS-18B20 数字温度传感器DS-18B20数字温度传感器，该产品采用美国DALLAS公司生产的 DS18B20可组网数字温度传感器芯片封装而成，具有耐磨耐碰，体积小，使用方便，封装形式多样，适用于各种狭小空间设备数字测温和控制领域。DS18B20数字温度传感器，具有3引脚TO92小体积封装形式；温度测量范围为55125,可编程为9位12位A/D转换精度，测温分辨率可达0.0625，被测温度用符号扩展的16位数字量的方式串行输出；其工作电源既可在远端引入，也可采用寄生电源方式产生；多个DS18B20可以并联到3根或2根线上，CPU只需一根端口线就能与诸多DS18B20通信，占用微处理器的端口较少，可节省大量的引线和逻辑电路。以上特点使DS18B20非常适用于远距离多点温度检测系统。1、 技术性能描述：1) 独特的单线接口方式，DS18B20在与微处理器连接时仅需要一条口线即可实现微处理器与DS18B20的双向通讯。2) 测温范围 55125，固有测温分辨率0.5。3) 支持多点组网功能，多个DS18B20可以并联在唯一的三线上，最多只能并联8个，如果数量过多，会使供电电源电压过低，从而造成信号传输的不稳定，实现多点测温4) 工作电源: 35V/DC5) 在使用中不需要任何外围元件6) 测量结果以912位数字量方式串行传送7) 不锈钢保护管直径 6 8) 适用于DN1525, DN40DN250各种介质工业管道和狭小空间设备测温9) 标准安装螺纹 M10X1, M12X1.5, G1/2任选10) PVC电缆直接出线或德式球型接线盒出线,便于与其它电器设备连接。2、应用范围：1) 该产品适用于冷冻库，粮仓，储罐，电讯机房，电力机房，电缆线槽等测温和控制领域2) 轴瓦，缸体，纺机，空调，等狭小空间工业设备测温和控制。3) 汽车空调、冰箱、冷柜、以及中低温干燥箱等。4) 供热/制冷管道热量计量，中央空调分户热能计量和工业领域测温和控制3、产品型号与规格：型 号测温范围安装螺纹电缆长度适用管道TS-18B20-55125无1.5 mTS-18B20A-55125M10X11.5mDN1525TS-18B20B-551251/2G接线盒DN40 604、接线说明：特点 独特的一线接口，只需要一条口线通信 多点能力，简化了分布式温度传感应用 无需外部元件 可用数据总线供电，电压范围为3.0 V至5.5 V 无需备用电源 测量温度范围为-55至+125 。华氏相当于是-67到257华氏度 -10至+85范围内精度为0.5温度传感器可编程的分辨率为912位 温度转换为12位数字格式最大值为750毫秒 用户可定义的非易失性温度报警设置 应用范围包括恒温控制，工业系统，消费电子产品温度计，或任何热敏感系统描述该DS18B20的数字温度计提供9至12位（可编程设备温度读数。信息被发送到/从DS18B20 通过1线接口，所以中央微处理器与DS18B20只有一个一条口线连接。为读写以及温度转换可以从数据线本身获得能量，不需要外接电源。 因为每一个DS18B20的包含一个独特的序号，多个ds18b20s可以同时存在于一条总线。这使得温度传感器放置在许多不同的地方。它的用途很多，包括空调环境控制，感测建筑物内温设备或机器，并进行过程监测和控制。 DS18B20内部结构主要由四部分组成：64位光刻ROM、温度传感器、非挥发的温度报警触发器TH和TL、配置寄存器。该装置信号线高的时候，内部电容器 储存能量通由1线通信线路给片子供电，而且在低电平期间为片子供电直至下一个高电平的到来重新充电。 DS18B20的电源也可以从外部3V-5 .5V的电压得到。DS18B20采用一线通信接口。因为一线通信接口，必须在先完成ROM设定，否则记忆和控制功能将无法使用。主要首先提供以下功能命令之一：1) 读ROM2) ROM匹配 3) 搜索ROM4) 跳过ROM5) 报警检查。这些指令操作作用在没有一个器件的64位光刻ROM序列号，可以在挂在一线上多个器件选定某一个器件，同时，总线也可以知道总线上挂有多少，什么样的设备。若指令成功地使DS18B20完成温度测量，数据存储在DS18B20的存储器。一个控制功能指挥指示DS18B20的演出测温。测量结果将被放置在DS18B20内存中，并可以让阅读发出记忆功能的指挥，阅读内容的片上存储器。温度报警触发器TH和TL都有一字节EEPROM 的数据。如果DS18B20不使用报警检查指令，这些寄存器可作为一般的用户记忆用途。在片上还载有配置字节以理想的解决温度数字转换。写TH,TL指令以及配置字节利用一个记忆功能的指令完成。通过缓存器读寄存器。所有数据的读，写都是从最低位开始。DS18B20有4个主要的数据部件： 1、光刻ROM中的64位序列号是出厂前被光刻好的，它可以看作是该DS18B20的地址序列码。64位光刻ROM的排列是：开始8位（28H）是产品类型标号，接着的48位是该DS18B20自身的序列号，最后8位是前面56位的循环冗余校验码（CRC=X8+X5+X4+1）。光刻ROM的作用是使每一个DS18B20都各不相同，这样就可以实现一根总线上挂接多个DS18B20的目的。2、DS18B20中的温度传感器可完成对温度的测量，以12位转化为例：用16位符号扩展的二进制补码读数形式提供，以0.0625/LSB形式表达，其中S为符号位
