【摘要】：随着经济的飞速发展,移动物体计数系统在展会统计、煤矿安全等国计民生场合发挥着越来越重要的作用。然而,现有计数系统却存在着一些明显不足:系统多采用基于视频检测、红外、压感、热感或者磁感等传统技术,普遍存在着检测准确度低、对环境变化敏感等缺点;同时现有系统多采用有线组网方式来互连多个计数子系统,因而存在部署不灵活、成本高等缺点。针对以上不足,本文提出了一种全新的基于超声波无线传感器网络的移动物体计数系统。该系统利用超声波技术进行移动物体的检测,并采用无线传感器网络互连各子计数系统,具备检测准确、抗干扰能力强、布置灵活、成本低廉等新特点。实验结果表明:该系统能够实现近98%的检测准确率,优于红外、磁感等传统检测手段。
[Abstract]:With the rapid development of economy, mobile object counting system plays a more and more important role in exhibition statistics, coal mine safety and other national economy and people's livelihood. However, there are some obvious shortcomings in the existing counting system: the traditional techniques based on video detection, infrared, pressure, thermal or magnetic sensing are used in the system, which have the disadvantages of low detection accuracy and sensitivity to environmental change. At the same time, most of the existing systems use wired network to interconnect multiple counting subsystems, so there are some disadvantages such as inflexible deployment and high cost. In order to solve the above problems, a new mobile object counting system based on ultrasonic wireless sensor network is proposed in this paper. The system uses ultrasonic technology to detect moving objects, and uses wireless sensor network to interconnect sub-counting system, which has the new characteristics of accurate detection, strong anti-interference ability, flexible layout, low cost and so on. The experimental results show that the system can achieve a detection accuracy of nearly 98%, which is superior to the traditional detection methods such as infrared, magnetic induction and so on.
