113、程序
说明: 113、基于51单片机老人生理智能监控GSM短信
本设计由STC89C52单片机电路+火焰传感器电路+加速度传感器+心率传感器电路+SIM800A_GSM模块电路+电源电路组成。
该系统实时监测老人是否跌倒,是否周围有火以及心率情况。
1、如果火焰传感器检测到火焰,则GSM向特定手机发送:Fire!
2、如果ADXL345检测到老人跌倒了,则GSM向特定手机发送:Fall!
3、如果心率传感器检测到老人心率高于120,则GSM向特定手机发送:High Heart!
4、注意本设计一次上电上述情况每个只能触发一次上报短信,不会连续发送,防止反复发送,请放心使用。
5、短信处理过程有GSM信号灯指示。
6、GSM模块是SIM800A,该模块和SIM900A电路程序完全兼容外观外形一模一样。(GSM SMS for elderly physiological intelligent monitoring based on 51 MCU
This design consists of STC89C52 MCU circuit + flame sensor circuit + acceleration sensor + heart rate sensor circuit + sim800a_ GSM module circuit + power supply circuit.
The system monitors whether the elderly fall down, whether there is fire around and heart rate in real time.
1. If the flame sensor detects a flame, the GSM sends: fire!
2. If adxl345 detects that an old man has fallen, the GSM sends a specific mobile phone: fall!
3. If the heart rate sensor detects that the heart rate of the elderly is higher than 120, the GSM sends a message to a specific mobile phone: high heart!
4. Pay attention to the design of a power on, each of the above conditions can only trigger a report SMS, will not be sent continuously, to prevent repeated sending, please rest assured to use.
5. SMS processing process is indicated by GSM signal light.)

serial_program_for_51
很完整的51串口程序
包括如下:
串口中断服务程序,仅需做简单调用即可完成串口输入输出的处理
出入均设有缓冲区,大小可任意设置。
可供使用的函数名:
char getbyte(void) 从接收缓冲区取一个byte,如不想等待则在调用前检测inbufsign是否为1。
getline(char idata *line, unsigned char n) 获取一行数据回车结束,必须定义最大输入字符数
putbyte(char c) 放入一个字节到发送缓冲区
putbytes(unsigned char *outplace,j) 放一串数据到发送缓冲区,自定义长度
putstring(unsigned char code *puts) 发送一个定义在程序存储区的字符串到串口
puthex(unsigned char c) 发送一个字节的hex码,分成两个字节发。
putchar(uchar c,uchar j) 输出一个无符号字符数的十进制表示,必须标示小数点的位置,自动删除前面无用的零
putint(uint ui,uchar j) 输出一个无符号整型数的十进制表示,必须标示小数点的位置,自动删除前面无用的零
delay(unsigned char d) 延时n x 100ns
putinbuf(uchar c) 人工输入一个字符到输入缓冲区
CR 发送一个回车换行(err)
