Embodiment 1

[0022] The top view structural diagram of the distributed intelligent scaffold base force state monitoring system of the present invention is as follows figure 1 as shown, figure 1 It is a schematic diagram of the system structure, and the number of scaffold bases that can be monitored by the distributed intelligent scaffold base stress state monitoring system is not limited to eight. The scaffolding base can be a fixed base or an adjustable base, and the fixed base can be an outer type or an inner type. The implementation principle of the present invention is as figure 2 shown.

[0023] The distributed intelligent scaffold base stress state monitoring system includes strain sensors integrated on the scaffold base and wireless multi-channel synchronous acquisition equipment.

[0024] Specifically, the strain sensor is integrated on the bottom plate of the scaffold base, the output of the strain sensor is connected to the input of the wireless multi-channel synchronous acqu...

Embodiment 2

[0032] Such as Figure 1-2 As shown, the structure and implementation principle of the distributed intelligent scaffold base force state monitoring system of the present invention are the same as those in Embodiment 1.

[0033] During specific implementation, the scaffolding on the entire construction site is divided into different areas, and the strain sensors integrated on the base of each scaffolding are connected to the wireless multi-channel synchronous acquisition equipment. The multi-channel A / D converter in the wireless multi-channel synchronous acquisition device converts the received analog signal into a digital signal and inputs it to the microcontroller. The microcontroller collects the stress state information of each scaffold base at the same time point, analyzes the comprehensive stress state of the scaffold base in each work area, and compares the stress conditions between different areas, thereby Judging whether there is subsidence, suspension or inclination ...

Abstract

The invention relates to the technical field of scaffold safety monitoring, in particular to a distributed intelligent scaffold base stress state monitoring system. The system comprises strain sensorsarranged on each scaffold base and unified wireless multichannel synchronous collection equipment, wherein each strain sensor is a resistance strain sensor; a resistance strain gage is connected withan electric bridge circuit for measuring the scaffold base stress state. The wireless multichannel synchronous collection equipment comprises an electric bridge circuit, a signal conditioner, a multichannel A / D converter, a microcontroller and a wireless transmission module. The output of the electric bride circuit is subjected to signal conditioning and is then connected with one input channel of the multichannel A / D converter; after A / D conversion, the output is input into the microcontroller. The microcontroller compares and analyzes the stress state of each scaffold base; whether the stress among the bases is uniform or not is judged; an early warning signal is given out when the early warning value is exceeded; the casualty accident caused by scaffold unstability is avoided.

Description

technical field [0001] The invention relates to the technical field of scaffold safety monitoring, in particular to a distributed intelligent scaffold base stress state monitoring system. Background technique [0002] Scaffolding is an indispensable temporary facility in building construction. It is a working platform or working channel set up to ensure the safety of high-altitude operations and smooth construction. It is widely used in structural construction, decoration construction, and installation and construction of equipment and pipelines. [0003] In recent years, my country's construction scaffold safety accidents have occurred frequently, whether it is the overturning and collapse caused by the overall or partial instability of the scaffold, or the dismantling of the scaffold and the fall of the workers on the scaffold, all of which have caused serious casualties. [0004] The steel pipe scaffolding pole is provided with a base, which can prevent sliding and uneven...
