当热线工作于温湿度变化场合时，其特征参数随之变化。为了保证测量的准确性，热线仪需随环境变化进行校准。本文设计了一种实时热线现场校准装置和遥测遥控系统，适用于野外和恶劣环境下的测量。该仪器在斜拉桥风致振动研究中准确地测量出了台风过境时的参数特性，显示了较强的适用性。 When the hotline work in the temperature and humidity changes occasion, its characteristic parameters change. In order to ensure the accuracy of the measurement, the hotline instrument needs to be calibrated according to the environment. This article designed a real-time hotline on-site calibration device and telemetry remote control system, suitable for field and harsh environments measurement. The instrument accurately measured the parameter characteristics of the typhoon transit during the wind-induced vibration study of the cable-stayed bridge and showed strong applicability.
