DS1302

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.)

说明：  自动加料机控制系统 以单片机实现 用于毕业设计 (Automatic feeder control system the MCU for graduation design)

基于51的C语言频率计，内涵仿真图，以实现空能(Based on 51 C-language frequency meter, meaning simulation diagram, in order to achieve air can)

AT89C51控制步进电机，实现正反转加减速，驱动芯片是ULN2803.(AT89C51 control the stepper motor to achieve reversing acceleration and deceleration, the driver chip is the ULN2803.)

一个指示灯闪烁的小程序，给大家做参考，个人认为还是有参考价值的。(A simple Led indicator program for glitter.)

可以用指令控制选择信道，设置发射功率，发送数据包（长度可选），接收数据包（接收时延可设），CC2430复位,内部温度传感器读取，定时器时长控制。底层函数基本做好，如果要加入新功能，可自行更改。(You can select the channel with the command control, set the transmit power, transmit data packet (lengths), receive data packets (receiver delay can be set), CC2430 reset, the internal temperature sensor reading, the timer duration control. Basic underlying function well, if you want to add new features to make changes.)

通过使用能。Keil 51工具和VC++来实现按键的功.(Achieved by using the Keil 51 tools and VC++ of the key functions.)

51单片机片上串口控制GPRS模块。用KEIL 软件调试成功。(51 MCU on-chip serial port to control the GPRS module. KEIL software debugging success.)
