【摘要】：本文来源于中国石油创新基金项目(2014D-5006-0603),该项目完成天然气井监测,数据的采集,存储和访问。在石油企业的会议中心,为了工作人员可以轻松便捷的读取和查看数据,本文利用Android平台设计了手机App通过GPRS从远程数据库读取数据,然后将读取到的数据通过WiFi发送到显示屏,提高了办公效率。本文设计了显示屏控制系统,硬件平台是以微控制器为中心,外围搭载了WiFi模块、VGA接口转换模块、LCD显示屏,通过接口之间的相互连接和转换,设计了硬件电路以及编写了相对应的控制程序。手机客户端的开发主要实现了查询与发送数据,一方面手机客户端采用HTTP协议与远程数据库通信进行查询数据;另一方面手机客户端从远程数据库将读取到的数据采用Socket套接字连接到硬件平台的WiFi模块,通过串口与微控制器进行通信,微控制器完成数据的解析、处理,转换,将数据整合为显示帧,并转换成VGA接口形式显示到LCD屏幕上。远程数据库的后台程序设计采用SSH架构,完成连接数据库,实现了手机客户端对远程数据库的访问。最后对显示屏控制系统进行了整体的测试,验证了手机客户端通过WiFi将数据发送到LCD屏的可行性,可以运用移动智能终端实现移动会议。
[Abstract]:This paper comes from the China Petroleum Innovation Fund (2014D-5006-0603), which completes the monitoring of natural gas wells, data acquisition, storage and access. In the conference center of the petroleum enterprise, in order for the staff to read and view the data easily and conveniently, this paper designs the mobile phone App to read the data from the remote database by using the Android platform. The read data is then sent to the display screen via WiFi, improving office efficiency. In this paper, the display screen control system is designed. The hardware platform is based on microcontroller, and the peripheral is equipped with WiFi module VGA interface conversion module and LCD display screen. The hardware circuit and the corresponding control program are designed. The development of mobile phone client mainly realizes the query and sending data. On the one hand, the mobile phone client uses HTTP protocol to communicate with the remote database for querying data; On the other hand, the mobile phone client uses socket to connect the read data from the remote database to the WiFi module of the hardware platform, communicates with the microcontroller through the serial port, and the microcontroller completes the data analysis, processing and conversion. The data is integrated into display frames and converted to VGA interface to display on the LCD screen. The background program of remote database is designed with SSH structure, which can connect the database and realize the access of the mobile phone client to the remote database. Finally, the display control system is tested, which verifies the feasibility of mobile phone client sending data to LCD screen through WiFi. Mobile conference can be realized by mobile intelligent terminal.
