【摘要】：近年来,随着我国经济的发展,资源工程和交通设施建设呈现出飞速发展的势头,隧道工程在基本设施建设中占到越来越重要的地位。但是,由于我国地质条件复杂,特别是西南部地区,频发的地质灾害不仅对隧道工程带来困难,同时还严重威胁到施工人员的生命安全,特别是水资源丰富的地区,发生突水事故对施工造成极大影响。在隧道施工的过程中,为保证施工质量、仪器设备正常运行以及施工人员的人身安全,对隧道进行含水量探测就成为隧道建设中的一个非常重要的环节。蓝牙技术是近年来兴起的一种新的无线通信技术,能够实现设备之间的短距离通信,广泛应用于电话系统、无线电缆等电子设备,通过无线的连接取代了设备之间的有线连接。同时,在所有隧道水量的超前探测方法中,激发极化法在隧道水量探测中得到了很好的应用。激发极化法是根据土壤、岩石等激发极化效应来探测地质水量的一种电法勘探方法。本文设计的探测仪是基于激发极化原理,利用二次电流激发极化法探测水源并确定水量,即可以判断含水构造的有无,确定含水构造的位置,推断出水量的大小。本文设计的基于蓝牙技术的直流探水仪,根据激发极化原理,将采集到的数据通过蓝牙通信传递到计算机,实现了数据无线通信,大大简化了设备之间的连接,增强了设备的可靠性。本论文主要介绍了基于蓝牙技术的直流探水仪,对涉及到的关键技术进行深入研究。首先,介绍了激发极化原理和蓝牙技术,从理论上分析了应用该原理在探水方面的有效性；其次,介绍了探测仪的设计方案和各部分的功能,在整体上把握总体设计思路；再次,分别从硬件和软件的层面,对信号采集、转换、存储、传输等环节进行设计；最后,将探测仪进行模块测试和现场测试,并对实验结果进行分析。
[Abstract]:In recent years, with the development of China's economy, resource engineering and traffic facilities construction show a rapid development momentum, tunnel engineering in infrastructure construction plays an increasingly important role. However, due to the complex geological conditions in China, especially in the southwestern region, frequent geological disasters not only bring difficulties to tunnel engineering, but also seriously threaten the safety of construction personnel, especially in areas rich in water resources. Water inrush has a great impact on the construction. In the process of tunnel construction, in order to ensure the construction quality, the normal operation of the equipment and the personal safety of the construction personnel, the detection of the water content of the tunnel has become a very important link in the tunnel construction. Bluetooth technology is a new wireless communication technology developed in recent years, which can realize the short distance communication between devices. It is widely used in telephone system, wireless cable and other electronic devices. It replaces the wired connection between devices through wireless connection. At the same time, the method of induced polarization has been applied to the detection of tunnel water in advance of all the tunnel water quantity detection methods. The induced polarization method is a kind of electrical prospecting method which detects the geological water quantity according to the induced polarization effect of soil and rock. The detector designed in this paper is based on the principle of induced polarization. The method of secondary current induced polarization is used to detect water source and determine the quantity of water, that is to say, the existence or not of water-bearing structure can be judged, the location of water-bearing structure can be determined, and the amount of water output can be inferred. The DC water detector based on Bluetooth technology is designed in this paper. According to the principle of excitation polarization, the collected data is transmitted to the computer through Bluetooth communication. The wireless data communication is realized, and the connection between devices is greatly simplified. The reliability of the equipment is enhanced. This paper mainly introduces the DC water detector based on Bluetooth technology, and deeply studies the key technology involved. Firstly, the principle of induced polarization and Bluetooth technology are introduced, and the effectiveness of applying this principle in water detection is analyzed theoretically. Secondly, the design scheme and functions of each part of the detector are introduced, and the overall design ideas are grasped. Thirdly, the signal acquisition, conversion, storage, transmission and other links are designed from the hardware and software level. Finally, the detector is tested by module and field test, and the experimental results are analyzed.
