Distributed scaffold stress state monitoring system

The invention discloses a distributed scaffold stress state monitoring system which comprises thin film sensors integrated on scaffolds and a unified wireless multi-channel synchronous acquisition device. The thin film sensors are only integrated at effective action points to efficiently monitor strain changes. The unified wireless multi-channel synchronous acquisition device includes an amplifying circuit, a signal conditioner, a multi-channel A/D converter, a microcontroller and a 433 RF transmission module. An output signal of the amplifying circuit is connected to an input channel of the multi-channel A/D converter after signal conditioning and is input into the microcontroller after A/D conversion. The microcontroller compares and analyzes the synchronously acquired stress states of scaffold fasteners and sends an early warning signal when the stress exceeds a threshold to avoid casualty accident caused by the instability of the scaffolds. 本发明公开了分布式脚手架受力状态监测系统，包括集成在各个脚手架上的薄膜传感器、统的无线多通道同步采集设备。薄膜传感器只集成在有效的
