代码说明：

Energy efficiency is the most important design goal for wireless sensor networks (WSNs). In this paper, we propose an energy-efficient cooperative MIMO scheme, which combines energy-efficient LEACH (EE-LEACH) protocol and cooperative MIMO. We name it as EE-LEACH-MIMO scheme. EE-LEACH is an improved LEACH algorithm, in which the network is partitioned to sectors with equal angle for avoiding the distribution non-uniformity of cluster heads. In EE-LEACH-MIMO scheme, the location and the residual energy of each node are considered when the cluster heads for clustering and cooperative nodes for MIMO system are chosen. For comparisons, LEACH, EE-LEACH, the simple cooperative scheme with LEACH and MIMO (LEACHMIMO), and EE-LEACH-MIMO scheme are simulated. The result shows that EE-LEACH-MIMO scheme can well balance the network load, save energy and prolong the network lifetime

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.)

ucosii51
这是一个用51单片机系统仿真ucosii工作的protues电路本系统包括扩展64k RAM的单片机系统和杨屹移植到51单片机的ucosii 系统使用方法： 1.安装Protues7.4版，然后用protues打开protues 8051 simulation 文件夹中的extern ram.DSN 文件 2.打开extern ram.DSN 后，双击单片机在弹出的窗口中的Program File 选项中选择yy.hex文件。 (yy.hex其实就是yy文件夹中keil文档编译出来的hex文件，yy文件夹是杨屹的ucos51 系统，用keil 2 可以打开) 3.在Clock Frequency选项中输入22.184M(杨屹的ucos51 用的是22.184M hz的单片机频率) 4.双击VTERM串口调试显示屏，在Baud Rate 选项中选择19200的波特率 5.保存，点击运行就可以看到经典的hello world 了。 (1. Protues7.4 version installed, and then open the protues folder protues 8051 simulation The extern ram.DSN file 2. Open extern ram.DSN, double-click the pop-up window of SCM in the Program File option, select yy.hex file. (yy.hex actually yy folder keil out of the document compiled hex files, yy folder is Yang Yi s ucos51 system, using keil 2 Can open) 3. In the Clock Frequency option to enter 22.184M (Yang Yi of the ucos51 using a microcontroller 22.184M hz frequency) 4. Double-click VTERM serial debug display, in the Baud Rate select 19200 baud rate options 5. Save, click Run you can see the classic hello world)
