摘要(中英文)
本系统实现了一个移动固话的功能,并且具有短信控制家电设备的功能。由电源模块、GSM模块、主控模块和串口模块四部分构成。电源模块主要是为系统提供所需的5V和4V电压,分别由5V 3A的电源适配器和芯片LM1086稳压得到;GSM模块用于接收手机用户发送的短消息命令并将其存储下来。主控模块的MCU采用ATMEL公司生产的AT89S52单片机,并通过单片机连接LCD1602显示模块和控制信号输出模块组成,负责设置GSM模块的参数和读取新短信内容以控制信号输出模块,并将新短信内容通过LCD1602显示;串口模块分为两部分,一部分是GSM模块和主控模块的串口连接,两者可以直接相连通信,另一部分用于系统调试时GSM模块和PC机的连接,两者的串口连接需要电平转换。
本课题实现了以GSM短消息为载体的控制信号传送,用户通过手机发送短信息命令“开”或“关”就可以通过GSM网络远程控制一个LED灯的亮灭,若短信命令不正确,则报错指示灯亮。并且,通过GSM模块与车载GPRS模块的相连,可以实现实时显示汽车位置的功能。
The system is a simple mobile posed of the power modules, GSM module, control module and serial interface module four also has the function of control the household electrical power modules are mainly for the system to provide the 4V voltage needed respectively, with 5V by 5V 3A power adapter and chip of LM1086 regulators get; GSM module for receiving cell phone users send text messages orders and store it down. The MCU control module pany production by MSP430F149 by microcontroller, and LCD display module and control connected signal output module. Responsible for setting the GSM module control module of parameters and read the new message content by the control signal output module, and will LCD1602 new message content through show. Serial interface module can be divided into two parts. Part of it is GSM module and control module of serial connection, both can directly munication; The other part was used in system adjustment GSM module and PC connection, both the serial link needs to level conversion.
This subject is realized with GSM short news as the carrier of control signals, the user through mobiles short message ordered to "on" or "off" can pass the work remote control A number of household electrical appliances lamp light out, if the mand not correct, the error indicator emit light. Through the GSM module connected to the vehicle GPRS module, ca
