Description: 呼吸监测GSM报警系统:通过热敏电阻电路采集相应的呼吸信号 然后使用硬件电路对相应的信号进行放大处理，再者进行数值比较得到相应的高低电平，再将此电平送入MSP430F149中，然后利用捕获程序计算两次呼吸之间的时间差，算出每分钟呼吸的次数。在12864液晶屏显示出来。当呼吸超出所设定的阈值时，单片机向SIM300手机模块发送要指令，并通过此模块向手机终端发送警报信息。-Respiration monitoring GSM alarm system: the corresponding respiratory signal collected by the thermistor circuit then use a hardware circuit to a signal corresponding to an enlargement processing Moreover numerical comparison to obtain the corresponding high and low, and then this level into the MSP430F149 The capture program, and then use the time difference between the two breathing calculation calculates the number of breaths per minute. 12864 LCD display. When breathing beyond the threshold set by the microcontroller to the SIM300 phone module Send To instructions, and send alarm information to the mobile terminal through this module.

Description: 由于太阳能充电系统多在户外，为了方便研究太阳能充电控制系统对蓄电池的充电情况，本文使用GPRS无线传输技术，设计了一套太阳能充电系统蓄电池的充电电压电流远程实时监测系统。系统的硬件部分由电压电流检测电路、单片机STC89C52RC、GPRS模块SIM300以及相应的外围电路构成，下位机软件由C语言编写并与硬件部分构成系统下位机部份，实现了对充电电压电流的信息采集以及数据的无线数传。上位机在LabVIEW2010环境下编写，具备友好的人机交互界面，实现了数据的远程接收、实时显示、数据库管理、报表生成和打印等功能。经过系统测试系统实现了对电压电流的远程监测。-As the solar charging system more outdoors, in order to facilitate the study of solar charge control system for charging the battery case, we use GPRS wireless transmission technology, we designed a solar charging system battery charge voltage and current remote monitoring system. The hardware part of the system by the voltage and current detecting circuit, microcontroller STC89C52RC, GPRS module SIM300 and corresponding peripheral circuits, lower computer software written in C language and hardware parts lower position machine part of the system, the realization of the charging voltage and current information collection and wireless data transmission of data. PC at LabVIEW2010 prepared environment, with friendly interactive interface, realize the remote receiving data, real-time display, management, report generation and printing. After the system test system enables remote monitoring of voltage and current.
