45、uch 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 valu

46、e 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 t

47、he 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 decr

48、eases 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

49、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

50、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 st

51、orages (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 temperat

52、ure 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 數(shù)字溫度傳感器DS-18B20數(shù)字溫度傳感器，該產品采用美國DALLAS公司生產的 DS18B20可組網數(shù)字溫度傳感器芯片封裝而成，具有耐磨耐碰，體積小，使用方便，封裝形式多樣，適用于各種狹

57、特的序號，多個ds18b20s可以同時存在于一條總線。這使得溫度傳感器放置在許多不同的地方。它的用途很多，包括空調環(huán)境控制，感測建筑物內溫設備或機器，并進行過程監(jiān)測和控制。 DS18B20內部結構主要由四部分組成：64位光刻ROM、溫度傳感器、非揮發(fā)的溫度報警觸發(fā)器TH和TL、配置寄存器。該裝置信號線高的時候，內部電容器 儲存能量通由1線通信線路給片子供電，而且在低電平期間為片子供電直至下一個高電平的到來重新充電。 DS18B20的電源也可以從外部3V-5 .5V的電壓得到。DS18B20采用一線通信接口。因為一線通信接口，必須在先完成ROM設定，否則記憶和控制功能將無法使用。主要首先提供以下

58、功能命令之一：1) 讀ROM2) ROM匹配 3) 搜索ROM4) 跳過ROM5) 報警檢查。這些指令操作作用在沒有一個器件的64位光刻ROM序列號，可以在掛在一線上多個器件選定某一個器件，同時，總線也可以知道總線上掛有多少，什么樣的設備。若指令成功地使DS18B20完成溫度測量，數(shù)據存儲在DS18B20的存儲器。一個控制功能指揮指示DS18B20的演出測溫。測量結果將被放置在DS18B20內存中，并可以讓閱讀發(fā)出記憶功能的指揮，閱讀內容的片上存儲器。溫度報警觸發(fā)器TH和TL都有一字節(jié)EEPROM 的數(shù)據。如果DS18B20不使用報警檢查指令，這些寄存器可作為一般的用戶記憶用途。在片上還載有配

59、置字節(jié)以理想的解決溫度數(shù)字轉換。寫TH,TL指令以及配置字節(jié)利用一個記憶功能的指令完成。通過緩存器讀寄存器。所有數(shù)據的讀，寫都是從最低位開始。DS18B20有4個主要的數(shù)據部件： 1、光刻ROM中的64位序列號是出廠前被光刻好的，它可以看作是該DS18B20的地址序列碼。64位光刻ROM的排列是：開始8位（28H）是產品類型標號，接著的48位是該DS18B20自身的序列號，最后8位是前面56位的循環(huán)冗余校驗碼（CRC=X8+X5+X4+1）。光刻ROM的作用是使每一個DS18B20都各不相同，這樣就可以實現(xiàn)一根總線上掛接多個DS18B20的目的。2、DS18B20中的溫度傳感器可完成對溫度的測量，以12位轉化為例：用16位符號擴展的二進制補碼讀數(shù)形式提供，以0.06
