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.)
