Airship capsule strain on-line monitoring device

The invention provides an airship capsule strain on-line monitoring device. The device comprises a collection module which is used for collecting the displacement generated between two points on the surface of an airship capsule to form displacement data, and a resolving module which is used for settling strain data of the surface through the displacement data, and can display the strain data to complete strain online monitoring. The airship capsule strain on-line monitoring device can carry out on-line monitoring on the strain of the airship capsule, fills the blank that a sensor can not carry out on-line monitoring on the strain of the airship capsule at present, and is simple in structure, high in measurement precision, convenient to install and low in cost. 本公开提供一种飞艇囊体应变在线监测装置，包括：采集模块，用于采集飞艇囊体表面的两点间产生的位移，形成位移数据；解算模块，用于通过所述位移数据结算出所述表面的应变数据，并能够展示所述应变数据，完成应变在线监测。能够对飞艇囊体的应变进行在线监测，填补了目前没有传感器能够对飞艇囊体进行应变在线监测的空白，装置结构简单，测量精度高，安装方便，成本低。
