【正文】 bus. After the DS18B20 receives the signal to wait for about 16 ~ 60μs, send out 60 ~ 240μs existences low pulses, the MCU indicate reposition successfully after receiving this signal[6]. When the MCU executes the program to flow diagram which the sensor DS18B20 measured temperature, it sends out the temperature transformation order. The MCU should wait for the sensor DS18B20 returns to the low signal. Once a sensor DS18B20 contacts with the bus not good or broken, the 共 4 頁(yè) 第 9 頁(yè) MCU will not read the low signal and will enters the endless loop for waiting. So we use a MCU?s timer interruption to solve this problem in system. 4 Conclusion After the field test, this system can realize the building temperature examination and control this system can be applied to other equipments testing and control in order to realize building intelligent management. While CAN bus is an effective support for distributed industrial control serial munication work, the system can also be widely applied to other needs realtime multipoint measurement and control areas. 中考滿分作文 中考網(wǎng) 中考資源網(wǎng) 上海中考網(wǎng) 北京中考網(wǎng) 中考優(yōu)秀作文 中考語(yǔ)文試卷 中考英語(yǔ)試卷 中考數(shù)學(xué)試卷 中 高考英語(yǔ)試卷 考試卷及答案 高考語(yǔ)文試卷 成人高考試卷 2021 高考試卷 江蘇高考試卷 2021 高考語(yǔ)文試卷 考 試百科網(wǎng)站以考試資訊為核心，提供最新最快最全面的考試資訊，包括報(bào)考指南、模擬試題、歷年真題、經(jīng)驗(yàn)技巧等信息。 外文原文應(yīng)以附件的方 式置于譯文之后。單片機(jī)會(huì) 等待傳感器 DS18B20 變?yōu)?低信號(hào)。 不同的樓宇，其內(nèi)部空間分布和結(jié)構(gòu)是不同的．為實(shí)現(xiàn)系統(tǒng)的構(gòu)建，筆者提出一種基于SJAl000 的 CAN通信平臺(tái)來(lái)實(shí)現(xiàn)各節(jié)點(diǎn)的可靠通信；在此基礎(chǔ)上，由主控制器實(shí)現(xiàn)對(duì)各檢測(cè)節(jié)點(diǎn)的溫度設(shè)定，實(shí)時(shí)檢測(cè)整幢樓宇溫度，并由 LCD 顯示結(jié)果，對(duì)異常情況進(jìn)行語(yǔ)音報(bào)警和控制 ，以實(shí)現(xiàn)節(jié)能目的．系統(tǒng)的設(shè)計(jì)目的是為了測(cè)量和控制分布在一棟建筑物內(nèi)各個(gè)房間的溫度，而測(cè)溫和控制節(jié)點(diǎn)是分散的，所以要通過(guò) CAN 總線實(shí)現(xiàn)控制臺(tái)和分布在建筑物的各個(gè)部分的控制節(jié)點(diǎn)相連，每個(gè)控制節(jié)點(diǎn)可以控制多個(gè)房間的溫度．系統(tǒng)結(jié)構(gòu)如圖 l所示． 2． 1 主控臺(tái)和硬件設(shè)計(jì) 控制臺(tái)是 AT89C52 單片機(jī)，為主控制器，連接報(bào)警模塊、存儲(chǔ)模塊、時(shí)鐘／日歷電路和人機(jī)接口電路，其結(jié)構(gòu)如圖 2 所示．控制節(jié)點(diǎn)也由單片機(jī)控制，連接溫度檢測(cè)模塊和 CAN 總線接口模塊。根據(jù)由主機(jī)控制在每個(gè)房間空調(diào)氣門系統(tǒng)接收的一定的溫度值。 圖 4 控制臺(tái)程 序結(jié)構(gòu)圖 共 4 頁(yè) 第 4 頁(yè) 指 導(dǎo) 教 師 評(píng) 語(yǔ) 外文翻譯成績(jī)： 指導(dǎo)教師簽字： 年 月 日 注： 1。 The twisted pair wire (coaxial cable) transmits the medium separately to meet to the chip of PCA82C250 pins CANH, CANL.

The system design goal is measure and control temperature in a building each room, because measured the temperate point and control point is dispersion, therefore the system uses the distributional structure, The console is connected each part of control pitch point distributing in the building through the CAN Bus. System structure diagram like figure 1 shows The console hardware design The AT89C52 MCU is the primarily controller in console, It connects with the 共 4 頁(yè) 第 6 頁(yè) warning module, the memory module, the clock/calendar electric circuit and the keyboard module. its structure drawing see Figure 2.
