【摘要】：隨著物聯(lián)網(wǎng)技術(shù)的發(fā)展,傳感器網(wǎng)絡(luò)成為各國關(guān)注和研究的焦點,其應(yīng)用現(xiàn)已遍及人們生活的各個領(lǐng)域。但是傳感器采集的數(shù)據(jù)在傳輸過程中需要穩(wěn)定的外部網(wǎng)絡(luò)支撐,這在一定程度上限制了傳感網(wǎng)絡(luò)的完全普及。為了減少成本,提高應(yīng)用的靈活性,一些無線傳輸芯片開始漸漸被人熟悉和使用。本文就是利用一款高性價比的無線芯片設(shè)計并制作了一套基于HW3000無線傳輸?shù)臄?shù)據(jù)監(jiān)測控制系統(tǒng)。HW3000是海爾公司的一款工業(yè)級低功耗射頻收發(fā)芯片,傳播距離遠,穿透力強且價格便宜,具有很好的實用性。本設(shè)計中,首先通過傳感電子器件對監(jiān)測區(qū)域進行實時數(shù)據(jù)采集,采集到的各類信號經(jīng)過單片機的數(shù)據(jù)轉(zhuǎn)換處理后,由無線模塊發(fā)送出去。其次,根據(jù)系統(tǒng)特點提出了一種可靠的拓撲結(jié)構(gòu)及簡單有效的通訊協(xié)議,并通過數(shù)據(jù)確認(rèn)重發(fā)機制和防碰撞機制保證數(shù)據(jù)傳輸?shù)姆�(wěn)定性和可靠性。在監(jiān)控端,將接收的數(shù)據(jù)上傳至PC機,在本系統(tǒng)設(shè)計的軟件界面上進行數(shù)據(jù)顯示與分析并設(shè)有報警和遠程反向控制系統(tǒng),大大提高了系統(tǒng)的安全性和便捷性。最后,本文選定了測試場景,把系統(tǒng)與實際應(yīng)用環(huán)境結(jié)合在一起,分別對系統(tǒng)的模塊性能、運行界面、監(jiān)測功能和反向控制進行了逐一測試。本系統(tǒng)對應(yīng)用場所沒有特殊的條件要求,成本低且靈活性好,可以用于工農(nóng)業(yè),也可以用于學(xué)校家居等,具有廣闊的應(yīng)用前景。
[Abstract]:With the development of Internet of things (IoT) technology, sensor networks have become the focus of attention and research in many countries. However, the data collected by sensors need stable external network support in the process of transmission, which to some extent limits the full popularity of sensor networks. In order to reduce costs and improve application flexibility, some wireless transmission chips are gradually becoming familiar and used. In this paper, a data monitoring and control system based on HW3000 wireless transmission is designed and fabricated by using a high performance and price ratio wireless chip. HW3000 is an industrial low power RF transceiver chip of Haier Company. The penetration is strong and the price is cheap, has the very good practicability. In this design, the real time data acquisition of the monitoring area is carried out through the sensor electronic device, and the collected signals are transmitted by the wireless module after the data conversion of the single chip microcomputer. Secondly, according to the characteristics of the system, a reliable topology and a simple and effective communication protocol are proposed, and the data transmission stability and reliability are guaranteed by the data confirmation retransmission mechanism and the anti-collision mechanism. At the monitoring end, the received data is uploaded to the PC, the data is displayed and analyzed on the software interface designed by the system, and the alarm and remote reverse control system is set up, which greatly improves the security and convenience of the system. Finally, this paper selects the test scenario, combines the system with the practical application environment, and tests the module performance, the running interface, the monitoring function and the reverse control one by one. The system has no special conditions for application, low cost and good flexibility. It can be used in industry and agriculture, as well as in school home, etc. It has a broad application prospect.
