Infrastructure/桥梁监测

我们如何帮助您

坎贝尔科学数据采集系统用于结构和地震监测项目,从简单的光束疲劳分析到结构力学研究,以连续监测桥梁和其他大型复杂结构。坎贝尔科学桥梁监测方法是我们的​​专利光谱分析(VSPERT®) technology that provides three advantages over the traditional time-domain method of reading vibrating-wire sensors:

  1. The highest measurement precision available for vibrating-wire sensors
  2. Sensor diagnostics to verify the performance and health of the sensors
  3. 测量噪声免疫力,消除了振动线传感器数据后处理的需求

VSPECT technology allows vibrating-wire sensors to be read dynamically up to rates of 333 Hz, providing dynamic as well as simultaneous measurements across the entire structure.

我们的年代ystems are used globally in remote, unattended, stationary, and portable monitoring projects for highway overpasses, roads, tunnels, buildings, retaining walls, overhead signage, lighting towers, and bridges. They are compatible with a wide variety of sensors and peripherals to provide unparalleled measurements of either static or dynamic stress, vibration, displacement, load, and tilt. Incorporating various weather sensors, you can monitor dynamic structural behavior—such as wind-induced vibration, wave impact stresses, unsafe conditions, natural structural frequency, and harmonic structural frequencies—and send broadcast alerts. When life is at stake, there is no reason not to use the very best.

Bridge Monitoring and Control

我们的系统的多功能性允许它们为每个应用程序定制。我们提供一系列数据记录器,从最基本的系统中,只有几个通道到可扩展的系统,可衡量数百个通道。根据数据记录器模型,扫描速率可以从几小时到100,000次编程到100,000次。测量类型,记录间隔和处理算法也是可编程的。数据记录器不仅提供高级测量功能,还可以控制外部设备。

板载处理指令集包含程序化算法,该算法处理测量和输出导致所需的度量单位。例如,数据可以显示为雨流或级别交叉直方图。这些雨流程和级联交叉算法允许加工长时间,而不仅仅是有限数量的循环。指令集还允许触发输出,以前捕获数据捕获能力。触发器可以基于传感器输出,时间和/或用户控制。例如,如果正在监视过桥,则可以由检测汽车的方法,地震,预编程时间或按下按钮来触发数据收集。

我们的数据记录器的控制功能与其可编程性相结合,允许它们基于时间或测量条件进行声音警报,启动电气设备或关闭设备。系统还可以向电话,寻呼机,无线电和其他设备拨出报告网站条件。可提供语音合成调制解调器,因此系统实际上可以调用并告诉您正在发生的事情。

用于桥梁监控的传感器

Because our data loggers are compatible with nearly every commercially available sensor, you can use the sensors that best meet your application. Typical sensors used for structural and seismic monitoring by our systems include:

  • Carlson strain meters
  • 振动线应变仪
  • foil strain gauges (set up in quarter, half, or full bridge strain configurations)
  • inclinometers
  • 裂缝和关节传感器
  • tilt sensors
  • piezoresistive accelerometers
  • piezoelectric accelerometers
  • 电容式加速度计
  • borehole accelerometers
  • 年代ervo force balance accelerometers

Because ourGRANITE™Data-Acquisition Systems integrate with different测量模块, each system has different channel types and programmable inputs. Channel types include analog (single-ended and differential), pulse counters, switched excitation, continuous analog output, digital I/O, and anti-aliasing filter. Using switched or continuous excitation channels, our data-acquisition systems provide excitation for ratiometric bridge measurements.

我们的GRANITE™Series allows you to customize a system with the channel types that best fit your application. The number and type of channels on most of our data-acquisition systems are expandable using multiplexers and other measurement peripherals.

Communications

用于检索,存储和显示数据的多个通信选项的可用性也允许自定义系统以满足确切的需求。现场通信选项包括直接连接到PC或笔记本电脑,PC卡,存储模块和数据记录键盘/显示器。电信选项包括短途,电话(包括语音合成和蜂窝电脑),射频,多数和卫星。

Software

我们基于Windows的软件简化了数据记录器编程,数据检索和报告生成。可以随时修改数据记录器程序以适应不同的传感器配置或新的数据处理要求。
