Automatic start-stop control system and method for large-span light steel structure roof snow removal device
The invention discloses an automatic start-stop control system for a snow removal device of a large-span light steel structure roof, which is characterized in that a stress detection device is arranged on a key component of the large-span light steel structure roof, when the stress is detected to exceed a limit value, whether the position of the roof has accumulated snow load is judged, and when two conditions are met at the same time, the snow removal device at the corresponding position is started; and the real-time stress is judged until the stress level recovers to a specified value, and the snow removal device is shut down. Compared with a traditional snow removing device, the design method has the advantages that the strain values of key components in a certain proportion and space distribution serve as triggering conditions, the stress level of the components is actually controlled within a reasonable range, the stress condition of the structure can be reflected more accurately, and structural safety is guaranteed.
本发明公开了大跨轻钢结构屋盖除雪装置自动启停控制系统，在大跨轻钢结构屋盖的关键构件上设置应力检测装置，当检测到应力超过限值时，判断屋面位置是否有积雪类荷载，同时满足两个条件时，启动相应位置的除雪装置，并判断实时应力，直至应力水平恢复到规定值时，关停除雪装置。与传统除雪装置相比，该设计方法以一定比例及空间分布的关键构件的应变值为触发条件，实际上是控制了构件的应力水平在合理范围内，更能准确反应结构的受力情况，确保结构安全。
