文中介绍了基于高性能单片机、24位高精度正负可读Σ-△型A/D转换器、高精度双轴重力加速度计、总线供电和无线蓝牙等技术,研制开发的一种探头与静力触探微机之间无需电缆连接,能够实现测试数据的实时监控,可任意设置单重甚至多重套管以完成深孔作业的新型无缆静力触探设备。经室内测试及现场与传统静力触探设备相对比,表明该新型无缆静力触探设备具有性能稳定、数据准确可靠、测试精度高、操作简便等特点。与传统静力触探设备相比,不但大大简化和减少了操作工序和劳动强度,提高了功效,而且与已有的存储式静力触探探头相比,能够实现对勘测数据的实时监控,同时勘探深度不受数据传输限制,非常适用于大深度静力触探试验的勘探施工作业。
In this paper, based on high performance single chip, 24-bit high-precision positive and negative readable Σ- △ A / D converter, high-precision two-axis gravity accelerometer, bus power supply and wireless Bluetooth technology, developed a probe and static The ability to touch the computer without the need for cable connections, enabling real-time monitoring of test data, can be arbitrarily set single or even multiple casing to complete the deep-hole operation of the new cable-free static probe equipment. The indoor test and the scene compared with the traditional static probe equipment, indicating that the new cable static probe equipment with stable performance, accurate and reliable data, high precision, easy to operate and so on. Compared with traditional static probe equipment, it not only greatly simplifies and reduces the operation procedure and labor intensity, and improves the efficiency, but also realizes the monitoring of survey data in real time compared with the existing storage type static probe probe, At the same time, exploration depth is not limited by data transmission, so it is very suitable for exploration and construction work in deep deep penetration test.
