基于PSOC3的多點溫度采集系統(tǒng)

1、電子系統(tǒng)綜合實訓(xùn) 基于PSOC3多點溫度采集系統(tǒng)一、 設(shè)計目的及要求1、基于PSOC3設(shè)計多點溫度采集系統(tǒng)，要求設(shè)立三個節(jié)點，即一個主機和兩個從機。2、主機為0號機，兩個從機分別為1號機和2號機。3、0號機與PC、1號機、2號機相連，1號機與0號機相連，2號機與0號機相連。4、1,2號機測得溫度后匯總給0號機，0號機測得本機溫度后一并將三個節(jié)點的數(shù)據(jù)報送給PC。5、PC可以向0號機發(fā)送命令，命令如下：（1）開啟溫度采樣 start_all 開啟所有節(jié)點溫度采樣 start_n (n=0,1,2)開啟單一節(jié)點溫度采樣（2）關(guān)閉溫度采樣 stop_all stop_n (n=0,1,2)（3）設(shè)置

2、溫度上、下限 tem_h_all=xx.x tem_l_all=xx.x tem_h_n=xx.x (n=0,1,2) tem_l_n=xx.x (n=0,1,2)（4）設(shè)置數(shù)據(jù)發(fā)送周期 t=x.xs（5）設(shè)置節(jié)點修改權(quán)限 au_all_en au_n_en (n=0,1,2) au_all_dis au_n_dis (n=0,1,2)6、在PC端顯示數(shù)據(jù)的格式如下： No.o：溫度，門限，權(quán)限； No.1：溫度，門限，權(quán)限； No.2：溫度，門限，權(quán)限；二、 設(shè)計方案本設(shè)計采用PSOC3實驗板，用到的模塊有LCD1602模塊，ADC模塊、LM35、UART串口通信、BELL蜂鳴器。檢測溫度時

3、，利用ADC轉(zhuǎn)換數(shù)據(jù)得到溫度值：溫度值=ADC讀數(shù)/實際電壓*216/參考電壓其中實際電壓設(shè)置為1.25V即1250mV，參考電壓為10mV。檢測到溫度后存儲并以一定格式在LCD上顯示數(shù)據(jù)。0號機通過不停的查詢PC端發(fā)出命令，來對本機或1、2號機器進行操作，0號機向PC報送數(shù)據(jù)時，因為要設(shè)置報送周期，所以報送數(shù)據(jù)是在一個循環(huán)里面，此時對于其他命令利用中斷來實現(xiàn)。0號機查詢1、2號子機的溫度時，首先向1 (2)號子機發(fā)送start_1 (start_2)之后等待1、2號機以字符串形式報送溫度數(shù)據(jù)，0號機收到數(shù)據(jù)后存儲。同時子機在不停的掃描從主機收到的指令，若收到start_1 (start_2)

4、則檢測溫度后存儲并以字符串形式報送給主機，若收到改變溫度上下限的命令則更改報警上下閾值。三、 原理圖設(shè)計及配置其中主機將用到所有模塊，子機只用到UART 1模塊、LCD、ADC、BELL。其中三個UART模塊配置相同，兩個Timer配置相同端口配置如下四、程序流程圖開始主機初始化各模塊Check0號機ADC轉(zhuǎn)換測得溫度，并存儲判斷溫 度蜂鳴器報警 溫度達到上下限 溫度未達到上下限LCD顯示溫度向1,2,號機發(fā)送start n(1,2)1,2號機反饋數(shù)據(jù)，0號機儲存等待接收PC機命令判斷命 令Start nStop,n Stop,n(0,1,2,all) start n (0,1,2,all)

5、一級中斷 一級中斷 不使能n號機發(fā)送權(quán)使能n號機發(fā)送權(quán) t=x.xscheck au_n_en 一級中斷au_n_discheck 或二級中斷tem_h_n Send 0 tem_l_n n=(0,1,2,all) Send 0溫度上下限，發(fā)送周期，權(quán)限發(fā)生改變 子機開始子機檢查命令 判斷命 令 Start n 其它采集n號機器溫度 tem_h_n tem_l_n判斷溫度 溫度達到上下限蜂鳴器報警 溫度未達到上下限向主機報送數(shù)據(jù)改變溫度警告上下限四、 測試結(jié)果五、 源代碼0號機（主機）#include #include uint8 ch=A;uint8 jflag=0x00;uint8 tem
