2、按钮后，1#、2#容器分别用泵P1、P2抽入碱和聚合物，抽满后各自的传感器发出信号，P1、P2关闭。2#容器在P2启动后10s开始启动加热器，当2#容器中的聚合物加热到60时，温度传感器发出信号，关闭加热器。当加热器关闭后，P3和P4启动，分别将1#、2#容器中的溶液送到3#反应器中，同时启动搅拌器，当3#满或1#、2#空，则P3、P4停止，P3、P4停止后搅拌器继续搅拌60s后，P5启动将混合液抽到产品池4#容器，直到4#满或3#空。成品将用P6抽走。为了提高生产效率，如果4#池没有满，当P3关闭时P1启动；P4关闭时P2启动，使1#、2#与3#并行工作。当按下停止按钮后，应该完成一个完整的

3、生产流程，即把1#、2#容器中的反应物用完，把3#容器所有混合液抽空到4#池，最终1#、2#、3#池处于空状态，然后才停止所有工作。综合题目设计要求，由于只需要用程序来控制反应流程，因而P1、P2、P3、P4、P5、P6以及加热器、搅拌器都用LED灯来同等代替，LED亮则表示开启，灭则表示关闭。用按键来表示容器的传感器以及开始键，按键按下则表示容器已满，反之则没有满。二、设计方案分析：当该化学反应装置开始键S1按下时，LED1和LED2开始点亮，表明开始向容器1和容器2开始分别注入碱和聚合物。与此同时在通过定时器的10秒定时后工作容器2的加热器开始工作，当容器1和容器2满状态时，由各自的传感器

4、即按键S2和S3按下，表明容器已满，则P1和P2停止工作即LED1和LED2同时熄灭。在开始注入液体时容器2中相对应的代表加热器工作的LED3开始点亮，由于容器2内有温度传感器，因此可以通过A/D转换把对应的温度模拟量转换成数字量，如果温度超过60摄氏度， P3和P4代表的LED4和LED5开始点亮，搅拌器对应的LED6也开始工作即点亮。把容器1和容器2的液体装入容器3的反应池中。当容器3满之后，P3和P4停止工作，即LED4和LED5熄灭，通过定时器0定时60秒来控制搅拌器工作即LED6再点亮60秒。之后待反应充分后把液体装入容器4中即LED7点亮，P5工作。当容器4中液体装满即按键S5按下

5、时，使P6开始工作即LED8开始点亮，如果容器4中液体未满时，将返回到刚开始状态继续注入液体使得继续工作。三、参考文献：1）周立功主编，ARM嵌入式系统基础教程，北京航空航天大学出版社，2008.92）开发板电路图，Y1_LPC 229X_V30.pdf四、总体流程设计图：LED3和LED6控制的加热器和A/D转换器LED3熄灭五 、设计流程图如下 各个模块对应关系如下：LED1P1 按键S1装置开始键按键S5#4满传感器按键S3#2满传感器按键S4#3满传感器按键S2#1满传感器LED7P5LED2P2 LED3加热器LED4P3 LED5P4 LED6搅拌器 LED8P6六、生产控制软件：

16、式，学习与ARM相关的知识是很有必要的，例如ARM接口技术，然后掌控ARM研发工具Keil，学会使用仿真器，写些接口方面的代码。其实，ARM的研发工具是初学者最应该花时间掌握的，这好比马车前进的轮子！这段时间大概需要2个月，因为ARM设计的东西太多了，开发工具也比一般的单片机复杂。 在学习ARM的初级阶段，购买一些相关书籍是少不了的，因为好的书籍一般都比较系统，这对于自己系统掌握ARM来说是很重要的。系统掌控好ARM接口知识后，接着再进行bootloader的学习,如uboot移植连同系统移植等，这时因为之前已有了ARM接口方面的知识，所以uboot学习及移植就会很快了。 关于bootload

17、er的学习，应该算是ARM里面初学者最难突破的环节，但是这又是必须的（个人认为），因为这是掌握ARM底层原理的最好方法！ 接着我们能够再移植kernel、制作自己的文档系统。这些都做好后，嵌入式研发环境就搭好了。下面就能够学习Linux系统编程及Linux驱动研发了。接口的基础会帮助我们更容易的理解驱动原理。同时，我们能够选择一个kernel里已支持的且您比较熟悉的接口的驱动如RTC等，进行分析和学习，并尝试进行修改或照着自己编写。按照这样的流程下来能够少走少许弯路，迅速入门，并且以一个比较合理的流程进行学习。八、附录#include LPC2294.H#include def.h#inclu
