基于PSOC3的多点温度采集系统

1、电子系统综合实训基于PSOC3多点温度采集系统一、设计目的及要求1、基于PSOC破计多点温度采集系统，要求设立三个节点，即一个主机和两个从机。2、主机为0号机，两个从机分别为1号机和2号机。3、0号机与PC.1号机、2号机相连，1号机与0号机相连，2号机与0号机相连。4、1,2号机测得温度后汇总给0号机，0号机测得本机温度后一并将三个节点的数据报送给PC5、PC可以向0号机发送命令，命令如下：(1)开启温度采样start_all开启所有节点温度采样start_n(n=0,1,2)开启单一节点温度采样(2)关闭温度采样stop_allstop_n(n=0,1,2)(3)设置温度上、下限temha

2、ll=xx.xCtemlall=xx.xCtemhn=xx.xC(n=0,1,2)tem_l_n=xx.xC(n=0,1,2)(4)设置数据发送周期t=x.xs(5)设置节点修改权限au_all_enau_n_en(n=0,1,2)au_all_disau_n_dis(n=0,1,2)6、在PC端显示数据的格式如下:No.o：温度，门限，权限;No.1:温度，门限，权限;No.2:温度，门限，权限;二、设计方案本设计采用PSOC坡验板，用到的模块有LCD1602模块，ADCft>LM35、UART串口通信、BELLW鸣器。检测温度时，利用ADC转换数据得到温度值：温度值=ADC读数/实际

3、电压*216/参考电压其中实际电压设置为1.25V即1250mV,参考电压为10mV。检测到温度后存储并以一定格式在LCD上显示数据。0号机通过不停的查询PC端发出命令，来对本机或1、2号机器进行操作，0号机向PC报送数据时，因为要设置报送周期，所以报送数据是在一个循环里面，此时对于其他命令利用中断来实现。0号机查询1、2号子机的温度时，首先向1(2)号子机发送start_1(start_2)之后等待1、2号机以字符串形式报送温度数据，0号机收到数据后存心。同时子机在不停的扫描从主机收到的指令，若收到start_1(start_2)则检测温度后存储并以字符用形式报送给主机，若收到改变温度上下限

4、而命令贝仙改报警上下阈值。三、原理图设计及配置其中主机将用到所有模块，子机只用到UART1模块、LCDADCBELL其中三个UART模块配置相同，两个Timer配置相同Configure'UART'我me；山足_1RXOnlyTXOnlyConfigureAdvanc“BulHnMode：»FullVART(TX+RX)JKalfDuplexDatasheetOKApplyCaneelConfigure'UARTt眄哈VART.lConfigureAdvancedBuilt-in4DClockSelection：/®IntQrn«lCloc
