摘要
针对大型高海拔空气簇射观测站水基切伦科夫探测阵列测距系统,提出了一种基于超声波测距技术的测距系统,并完成软硬件设计。该系统的下位机以LVCN318和PLC为核心,主要完成数据的采集与处理,上位机部分基于OPC技术,实现上位机与PLC的通信以及数据的显示与存储。基于该系统分别进行了障碍物测距与液位测量实验,实验研究表明,液位测量与障碍物距离测量的误差皆小于11mm,在LVCN318的误差范围内,为水基切伦科夫探测阵列测距系统的设计与研制奠定了基础。
The ultrasonic distance measuring system used to the Water Cherenkov Detector Array in Large High Altitude Air Shower Observatory project is designed in this paper. Slave computer of the ultrasonic distance system based on LVCN318 and PLC achieves the acquisition and processing of data. Upper computer based on OPC achieves the communication between upper computer and PLC, displays and stores data. The measurement of obstacle distance and level using this ranging system shows that measuring errors of objects are less than llmm and within the measuring error of LVCN318, which is helpful for the design and development of Water Cherenkov Detector Array＇s ranging system.
