6 总结与展望
6.1 总结
该设计通过分析自动窗帘系统的现状和人们对自动窗帘系统功能的需求，对自动窗帘系统控制器进行总体设计。总体设计采用步进电机为单片机控制元件，执行窗帘开闭的主要任务；以GSM模块来检测窗帘是否执行开关的状态；以光敏电阻为检测元件，提供单片机外界光照变化；以红外检测电路，实现手动控制；以89C52单片机为主控制芯片，控制整个系统运行；此外辅助以按键和显示电路，在各模块的配合下，最终实现自动窗帘控制系统的智能化要求。 6.2 展望
由于Protues仿真过软件中没有无线模块，所以只能在硬件设备上调试无线模块，刚开始调试时给系统上电后，液晶显示正常，电机转动正常，但是无法发出短信，经过不断地修改程序，不断地调试后，也实现了发短信的功能。还有就是无线模块存在不稳定性，信号易受区域影响，所以最好使用11.0592M晶振，因为可以得到精确的波特率，使串口通信的可靠度更高，稳定性更好，实用价值也更高。
毕业设计过程中，由于自我知识储备、实验器材和时间的局限性，完成的不是那么完善。本系统还有几个需要改进的地方：
(1）由于设计硬件的性价比，本次设计使用的都是平常的器件，虽然基本实现了本次设计的要求，但是存在着一定的局限性。如果使用wifi或zigbee技术的话，会大大提高系统的可用性，实用效果会更好，用户无论是否在家都可以无线控制窗帘的开关，当发现温度不高或者室内光线较暗时，用户也可以无线控制窗帘。
(2)在报警模块部分可以加入发光器件，实现声光报警。
通过以上改进措施，智能窗帘才会有很强的实用性，所以该系统将会有更大的应用前景。

Abstrct: This paper introduces a mobile phone short message control method in smart home based on
GSM (Global System for Mobile communications). AT commands and the system structure is illustrated in detail. The hardware system including STC89C51 and TC35i is presented. The software framework is also analyzed clearly in this paper. In addition, some other potential application areas and its direction of development in future are given at last.
Keywords: GSM; Smart Home; STC89C51; Wireless Communication 1. Introduction
As the Internet of things (iot) [1] global coverage, the popular trend of smart home, look for it. All the control and communication method rushed to the area: GSM, WiFi, bluetooth, ZigBee,. They are trying to solve the problem of the intelligent world [2]. In these solutions, GSM mobile phones have a comprehensive way to communicate a prominent position in modern society.
GSM is a kind of digital mobile communication network. In recent years has developed rapidly. With the short message service is a kind of important business based on GSM network. It's simple and efficient performance, and relatively low cost absorb the customers. In addition, the possibility of many types of remote monitoring technology, it must be the most convenient and most popular way in the smart home control, because people can monitor their home anywhere, anytime and anywhere. In this article, I will give you a good smart home solution based on GSM and explain the realization of software and hardware. 2. System Framework
The GSM control system contains the communication part, the control center and the object to be controlled. Figure 1 is the system block diagram.
In this system, GSM module plays the communication role. STC89C516RD+ bears the task of a control center. The relay module connected to home appliances is the object to be controlled. There are several channels of relays on the module. Each connects to a different home appliance.
The GSM module with a smart card is responsible for receiving text messages from the GSM network and transmitting the short message from the local MCU (STC89C516RD+) to the GSM network. It also receives message command from user’s mobile and sends the cor- responding command to the control center STC89C- 516RD+. The controller analysis the command and conducts the relay to open or close the anticipated cannel, such to open or close the related appliance. After this, the control center indicates the GSM module to send feedback message to the user terminal. 3. AT Commands
MCU communicate with GSM module through AT (Attention Commands) [4]. AT command set is the interface standard between TE (terminal equipment) and TA (terminal adaptor), as well as between DTE (data terminal equipment) and DCE (data circuit terminal equipment). In the early 1990s, AT command set

is only used in the operation of modem. With a series of evolution, AT commands are added GSM07.05 standards. Up to now, Most of the GSM modules support this standard. 3.1. The Syntax of Basic AT Commands
Each AT command must begin with “AT” or “at”, and end with
3.2. General AT Commands
The AT commands used in this remote control system are shown in Table 2. [5] 4. Hardware Structure
Figure 2 is the picture of the mobile phone control system. As showed in the picture, there are two boards and a GSM module in the system. The board above is the relay module and the bellow one is a control center board with STC89C516RD+ on it. The GSM module is connected to the center board through a pair of UART ports of STC89C516RD+ controller. Figure 3 is the hardware structure of the system.
