利用通讯模块进行数据通信，就是将数据体作为短消息的内容，从发送方的通讯模块发送出去，通过短消息中心进行转发，接收方通讯模块收到此短消息后即存储在SIM卡上，模块外接的控制器（如单片机、计算机等）从模块中读取短消息后，根据需要将无用的信息去除，取出有效信息，然后将SIM卡中的短消息删除，这样就完成一次单向数据的传输。利用通讯模块的短消息方式实现数据的发送和接收具有通信成本低、系统容量大、抗干扰能力强等优点，而且短消息经过服务中心再到达目的地的特点使通讯模块无需24小时开机，降低了系统功耗，特别适合遥控、遥测、远程信息处理和通信等领域。-GSM

1．任意选取一个灰度图像和彩色图像，对算法中若干关键语句中的参数进行调整，得出不同的实验结果，并对这些结果进行分析。 2．根据自己所学知识，提出自己的轮廓线提取方法，与简单阈值法进行比较分析。 3．练习matlab自带算子的检测结果。 -1. Arbitrarily select a gray-scale images and color images, several key statements on the algorithm to adjust the parameters, results in different experimental results, and these results were analyzed. 2. Learned based on their knowledge, put forward its own contour extraction method, with a simple threshold method for comparative analysis. 3. Matlab built-operator practice test results.

运放选型 运算放大器的结构形式主要有三种：模块、混合电路和单片集成电路。对于设计工程师来说，不仅是要知道所用产品的型号，而且还应熟悉生产这些产品的工艺，从而能够从一类放大器中选出一种放大器做特定的应用。-Selection of operational amplifier OPAMP structure There are three main types: modules, hybrid circuits and monolithic integrated circuit. Design Engineer for example, not only to know the product you are using models, but also familiar with the production process of these products in order to be able to elect one Class A amplifier amplifier make specific applications.
