【摘要】：随着物联网技术的发展,传感器网络成为各国关注和研究的焦点,其应用现已遍及人们生活的各个领域。但是传感器采集的数据在传输过程中需要稳定的外部网络支撑,这在一定程度上限制了传感网络的完全普及。为了减少成本,提高应用的灵活性,一些无线传输芯片开始渐渐被人熟悉和使用。本文就是利用一款高性价比的无线芯片设计并制作了一套基于HW3000无线传输的数据监测控制系统。HW3000是海尔公司的一款工业级低功耗射频收发芯片,传播距离远,穿透力强且价格便宜,具有很好的实用性。本设计中,首先通过传感电子器件对监测区域进行实时数据采集,采集到的各类信号经过单片机的数据转换处理后,由无线模块发送出去。其次,根据系统特点提出了一种可靠的拓扑结构及简单有效的通讯协议,并通过数据确认重发机制和防碰撞机制保证数据传输的稳定性和可靠性。在监控端,将接收的数据上传至PC机,在本系统设计的软件界面上进行数据显示与分析并设有报警和远程反向控制系统,大大提高了系统的安全性和便捷性。最后,本文选定了测试场景,把系统与实际应用环境结合在一起,分别对系统的模块性能、运行界面、监测功能和反向控制进行了逐一测试。本系统对应用场所没有特殊的条件要求,成本低且灵活性好,可以用于工农业,也可以用于学校家居等,具有广阔的应用前景。
[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.
