【正文】 . In order to achieve the voltage conversion the system use the way of resistors sharing voltage.單片機(jī)與TC35I之間的通信是通過串行，和速率是9600。municationsmode是8位異步一個(gè)起始位，8位數(shù)據(jù)位，1位停止。但TC35i串行輸入要求的CMOS電平，和89C52單片機(jī)的串行輸出需要TTL電平。為了實(shí)現(xiàn)電壓轉(zhuǎn)換系統(tǒng)使用電阻共享電壓的方式圖4 nRF905應(yīng)用示意圖圖5 TC35i模塊與單片機(jī)的接口電路軟件設(shè)計(jì)軟件系統(tǒng)包括數(shù)據(jù)采集模塊、溫度補(bǔ)償模塊和無線收發(fā)模塊無線發(fā)送程序，nRF905發(fā)送數(shù)據(jù)的過程如下：1）當(dāng)有數(shù)據(jù)要發(fā)送，單片機(jī)把收信人的地址和數(shù)據(jù)以nRF905按時(shí)間順序的SPI接口。然后把要發(fā)送的數(shù)據(jù)發(fā)送到發(fā)送緩沖器寄存器，WTP命令寫入數(shù)據(jù)寄存器和發(fā)送TX的有效載荷，WTA命令寫德克薩斯州TX地址寄存器地址。2）微控制器設(shè)置trx_ce = 1和tx_en = 1刺激shockbursttm nRF905發(fā)送方式。當(dāng)數(shù)據(jù)傳輸完成后，數(shù)據(jù)準(zhǔn)備好引腳設(shè)置高；3) Beacause of AUTO_RETRAN being high, the data of nRF905 is constantly reissued until3）的auto_retran高因?yàn)?，nRF905芯片的數(shù)據(jù)是不斷地重新發(fā)布到TRX_CE=0.trx_ce = 0。4) when TRX_CE pin is set low, means the data transmission pleted and nRF905 enter idlemode.4）當(dāng)trx_ce引腳設(shè)置低，意味著數(shù)據(jù)傳輸完成，進(jìn)入idlemode nRF905。無線接收程序，nRF905接收數(shù)據(jù)的過程如下：1）當(dāng)TRX _這= 1和TX _ = 0，nRF905 enters shockbursttm receive模式不斷和等待接收數(shù)據(jù)的檢查2）當(dāng)nRF905檢測(cè)載體具有相同的頻段，載波檢測(cè)引腳將被設(shè)置高。3）當(dāng)nRF905接收相匹配的地址，地址匹配引腳將被設(shè)置高。4）當(dāng)分組正確接收，字頭，地址和CRC比特將自動(dòng)removed, and the data ready pin will be set high.除去，和數(shù)據(jù)準(zhǔn)備好引腳將被設(shè)置高。5) MCU set TRX_CE to 0, and nRF905 enter to idle mode.5）設(shè)置為“0”trx_ce單片機(jī)和nRF905，進(jìn)入空閑模式。6) When all the data received, nRF905 set data ready pin and address matching pin to 0, and6）當(dāng)接收的所有數(shù)據(jù)集，nRF905的數(shù)據(jù)準(zhǔn)備好引腳和地址匹配引腳到“0”，和nRF905 turn to shutdown mode or ShockBurstTM transmitmode and receive mode.nRF905轉(zhuǎn)向模式或關(guān)機(jī)shockbursttm transmitmode和接收模式。圖6無線數(shù)據(jù)傳輸?shù)牧鞒虉D圖7無線接收數(shù)據(jù)流程圖 摘要設(shè)計(jì)了一種檢測(cè)可燃?xì)怏w濃度的裝置，具有無線收發(fā)器功能，可以發(fā)送報(bào)警信息到用戶的移動(dòng)迅速通過GSM實(shí)驗(yàn)結(jié)果表明，該裝置具有較高的精度，穩(wěn)定性和可靠性。它可以滿足大多數(shù)這需要可燃?xì)怏w濃度的實(shí)時(shí)監(jiān)測(cè)中的應(yīng)用。工具書類【1】劉氏，陳王Q，H G，吃。電容層析成像技術(shù)對(duì)氣固兩相流循環(huán)流化床的研究[J]測(cè)量。流量測(cè)量儀表，2005,16（3）：135144。measurement for circulating fluidized beds [J].Flow Measurement and Instrumentation，2005，16 (23):135144.
