摘 要：移动空间坐标测量系统(MScMS)是一个由意大利都灵大学生产系统与商务经济系的工业测量与质量工程实验室的实验基础之上发展起来的无线传感器主导网络。它的功能是用来实现简单和快速地进行大规模室内三维测量。
该系统由三个基本部分组成：一个无线传感器设备群(称为“蟋蟀”)，一个移动的嗅探器和一台用于储存和计算数据的PC机。蟋蟀和移动嗅探器利用了超声波收发器(US)以计算相互之间的距离。
这个系统以空间坐标的方式使位置计算成为了可能，这种方式是通过物体的尖端与嗅探器的“接触”实现的。
为了避免这个系统发生错误，如超声波的衍射和发射、外界因素（例如钥匙碰撞产生的响声、氖光闪烁等）对超声波的干扰、软件不兼容的解决方案等，MScMS系统运用了统计学试验来进行在线诊断。这篇文章对 “基于模型的能源诊断学”、“基于模型的距离诊断学”、和“传感器物理诊断学” 这三个问题进行了详细的论述。对于每个测量，如果所有这些试验都通过了，则测量的结果会被认为是一个确实可信的特定系数，否则，测量结果会被拒绝。

Abstract:
Mobile Spatial coordinate Measuring System (MScMS) is a wireless-sensor-network based systemdeveloped at the industrial metrology and quality engineering laboratory of DISPEA – Politecnico di Torino. It has been designed to perform simple and rapid indoor dimensional measurements of large-size volumes (large-scale metrology).
It is made up of three basic parts: a “constellation” of wireless devices (Crickets), a mobile probe, and a PC to store and elaborate data. Crickets and mobile probe utilize ultrasound (US) transceivers in order to evaluate mutual distances.
The system makes it possible to calculate the position – in terms of spatial coordinates – of the object points “touched” by the probe. Acquired data are then available for different types of elaboration (determination of distances, curves or surfaces of measured objects).
In order to protect the system against causes of error such as, for example, US signal diffraction and reflection, external uncontrolled US sources (key jingling, neon blinking, etc.), or software non-acceptable solutions, MScMS implements some statistical tests for on-line diagnostics. Three of them are deeply analyzed in this paper: “energy model-based diagnostics”, “distance model-based diagnostics”, and “sensor physical diagnostics”. For each measurement, if all these tests are satisfied at once, the measured result may be considered acceptable with a specific confidence coefficient. Otherwise, the measurement is rejected.
After a general description of the MScMS, the paper focuses on the description of these three online
diagnostic tools. Some preliminary results achieved by the system prototype are also presented and discussed. |
