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.)

Frequency
PIC （PIC16F886） 做的简单频率计
用TMR0定时1s，将待测信号从T1CKI脚输入，用TMR1进行计数，读出TMR1H，TMR1L的值就是频率
单片机：PIC16F886
显示：LCD1602
编程语言：PIC C
附Proteus仿真。(PIC (PIC16F886) to do a simple frequency counter TMR0 timer with 1s, the test signal input pin from T1CKI with TMR1 count, read TMR1H, TMR1L value is the frequency of the microcontroller: PIC16F886 display: LCD1602 with Proteus simulation.)

ServiceBrokerExtSource
SQL Server 2005 Service Broker (SSB) is an asynchronous messaging technology built into SQL Server. With SSB, you essentially get the power of messaging technologies like Microsoft Message Queue (MSMQ) combined with the relational database capabilities of SQL Server, all controlled with Transact SQL statements(SQL Server 2005 Service Broker (SSB) is an a synchronous messaging technology built into S QL Server.
