教学内容

项目任务：利用STM32实验箱（实验用实验箱），实现一定功能。

项目名称：温度和亮度监测系统

项目基本功能具体要求：

（1）利用STM32实验箱两路ADC输入（一路热敏电阻输入，一路光敏电阻输入）,可实现对温度和亮度信号的采集。

（2）采集到得数据可以发送给PC机，PC机可以通过串口助手显示出，或自编软件。

（3）此系统具有报警的功能，当采集到得温度和亮度值超出了最低和最高设定值时，停止采集，并把报警状态发送给PC。

（4）此系统具有良好的人机接口。

(a)在系统启动时，可在PC上显示交互菜单shell，当输入一定的指令后，可以：

①启动监测系统，系统开始工作。

②停止监测采集,系统停止功能。

③可设定温度和亮度的最高最低阀值，当超过阀值时，系统会报警。

(b)按钮功能键作用。

通过按钮可以控制：

①启动监测系统,系统开始工作。

②停止监测采集,系统停止功能。

(c) 通过LED指示灯显示显示各种状态。

①显示正常工作状态。

②显示超过高阀值状态。

③显示低于低阀值状态。

能完成的任务有以下列表：

（1）温度与亮度信号采集：热敏电阻是内置并与单片机的ADC接口连接，所以可以直接从芯片ADC获取转换后的值。但由于不太清楚转换后的值的格式以及如何计算转换成温度与电压值，所以就直接输出到PC交互端。

（2）传送数据：通过USART口使用中断方式传送数据。

（3）报警功能：在芯片程序与PC交互端都可以设定温度与电压的阀值，当超过阀值时芯片会亮灯报警，PC交互端也会显示警告信息。

（4）人机交互：基本都实现，唯一缺陷就是温度和电压的最高最低阀值是存储在程序（芯片与PC端口程序），没有存储在外部存储器，所以修改只能是在程序运行时，芯片断电后又恢复到默认值。

也可以自选题目，但需要首先与老师沟通好。

Teaching Goal and Basic Requirements

Upon completion of the course, students will acquire the following abilities:

(1) Mastering the development of embedded systems technology, and having embedded system development and innovation awareness

(2) Analyzing an actual embedded system

(3) Designing an actual embedded system

(4) Need some knowledge for electric, computer architecture etc.

Content

Task Objective: Design and implement some specific functions based on embedded system.

Reference Project Title:

Project Name: Temperature and voltage monitoring system.

Basic Requirements:

 (1) Implement a system which collects temperature and voltage signal through two channels of ADC input.(One using thermistor input and the other using voltage input)

（2）The collected data can be transferred to PC. PC can display the data using COM assistant or other software programmed by yourself。

The system has alarm function which can be triggered when the collected temperature and voltage is beyond the maximum value or below the minimum value.

The system should implement fine human-machine interface:

(a)When the system starts， PC can display a shell console。After type in specific command,the shell can:

① make the monitoring system start to work.

② stop the monitoring system.

③ set the maximum and minimum values of temperature and voltage.

(b)The Button function:

We can push button to:

①make the monitoring system start to work.

②stop the monitoring system.

(c)The LED lights can show the different states of the system

①Normal working state

②beyond max value state.

③below min values state.

Since we are not familiar with the development platform, it is hard to accomplish all the functions. The functions that can be achieved is listed as follows:

(1)The temperature and voltage signal collection:

The thermistor is built-in and connected to MCU. We can get the value after ADC transformation directly. But we don’t know the format of the value and have no idea how to calculate the temperature and volage using the value, we just send the value to PC.

(2)Data transmission:

Transfer data through USART by using interrupt mode.

(3)Alarm Function.

The maximum value and minimum value both can be set through PC or the system. When the value is out of range(alarm),the system LED light turns on and PC will display an alarm message too.

(4)Human-machine interface:

Almost finished, except the maximum and minimum value is stored in the program instead of external storage. Consequently, the value will recovery to default value when power-off.
