【摘要】：本文來(lái)源于中國(guó)石油創(chuàng)新基金項(xiàng)目(2014D-5006-0603),該項(xiàng)目完成天然氣井監(jiān)測(cè),數(shù)據(jù)的采集,存儲(chǔ)和訪問(wèn)。在石油企業(yè)的會(huì)議中心,為了工作人員可以輕松便捷的讀取和查看數(shù)據(jù),本文利用Android平臺(tái)設(shè)計(jì)了手機(jī)App通過(guò)GPRS從遠(yuǎn)程數(shù)據(jù)庫(kù)讀取數(shù)據(jù),然后將讀取到的數(shù)據(jù)通過(guò)WiFi發(fā)送到顯示屏,提高了辦公效率。本文設(shè)計(jì)了顯示屏控制系統(tǒng),硬件平臺(tái)是以微控制器為中心,外圍搭載了WiFi模塊、VGA接口轉(zhuǎn)換模塊、LCD顯示屏,通過(guò)接口之間的相互連接和轉(zhuǎn)換,設(shè)計(jì)了硬件電路以及編寫(xiě)了相對(duì)應(yīng)的控制程序。手機(jī)客戶端的開(kāi)發(fā)主要實(shí)現(xiàn)了查詢與發(fā)送數(shù)據(jù),一方面手機(jī)客戶端采用HTTP協(xié)議與遠(yuǎn)程數(shù)據(jù)庫(kù)通信進(jìn)行查詢數(shù)據(jù);另一方面手機(jī)客戶端從遠(yuǎn)程數(shù)據(jù)庫(kù)將讀取到的數(shù)據(jù)采用Socket套接字連接到硬件平臺(tái)的WiFi模塊,通過(guò)串口與微控制器進(jìn)行通信,微控制器完成數(shù)據(jù)的解析、處理,轉(zhuǎn)換,將數(shù)據(jù)整合為顯示幀,并轉(zhuǎn)換成VGA接口形式顯示到LCD屏幕上。遠(yuǎn)程數(shù)據(jù)庫(kù)的后臺(tái)程序設(shè)計(jì)采用SSH架構(gòu),完成連接數(shù)據(jù)庫(kù),實(shí)現(xiàn)了手機(jī)客戶端對(duì)遠(yuǎn)程數(shù)據(jù)庫(kù)的訪問(wèn)。最后對(duì)顯示屏控制系統(tǒng)進(jìn)行了整體的測(cè)試,驗(yàn)證了手機(jī)客戶端通過(guò)WiFi將數(shù)據(jù)發(fā)送到LCD屏的可行性,可以運(yùn)用移動(dòng)智能終端實(shí)現(xiàn)移動(dòng)會(huì)議。
[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.
