Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] The circuit diagram of the strain acquisition node is as follows: Figure 6 shown. Resistive strain gauges are selected as strain sensors for strain acquisition nodes. In order to improve its stability and output sensitivity and reduce power consumption, high resistance strain gauges are often used, such as model BF1K-3AA. The output of the strain gauge full bridge circuit is transformed into a standard voltage signal through the internal strain transformation circuit of the node. The present invention adopts the amplifier AD623 for a single power supply dedicated integrated instrument as the transformation circuit. The core component microprocessor of acquisition and control adopts CC2530. As Zigbee's dedicated control chip CC2530 is an 8-bit high-performance low-power microprocessor, and has five different operating power supply modes, and ha...

Abstract

The invention discloses a static structural testing data collection system based on Zigbee wireless communication. The Zigbee wireless network of the collection system adopts a star-shaped structure, and the data collection system includes a plurality of data collection terminal nodes, a coordinator node and a computer, wherein the data of strain, displacement and load, all collected by the data collection terminal nodes, are transmitted to the coordinator node in a wireless transmission mode, and the coordinator node is linked with the computer through USB to achieve the sending, reception and dispose of data; the data collection terminal nodes and the coordinator node all adopt a low-power-consumption design; power of the data collection terminal nodes is supplied by batteries, and power of the coordinator node is supplied by the computer through the USB; the system can be used in a condition without AC220 V of power. The data collection terminal nodes of the static structural testing data collection system based on Zigbee wireless communication can achieve the conversion and transmission of signals, data collection and data wireless transmission, and the static structural testing data collection system has the advantages of being simple in the integral system structure and pretty high in a price performance ratio, and decreasing workload and work strength by canceling a site arrangement of signal wires.

Description

technical field [0001] The invention relates to the technical field of structural static experiment data acquisition, in particular to a structural static experiment data acquisition system based on Zigbee wireless communication. Background technique [0002] Structural static test is a mechanical test to determine the strength, stiffness or stability of engineering structures under static loads. In addition to the loading test of the load-bearing parts of the structure, the overall or partial load-bearing performance test of the structure is also required. The experimental objects can be solid structures or models of aircraft, rockets, ships, large-scale equipment mechanical structures, or building structures such as steel structures, concrete structures, masonry structures, wood structures, etc., generally including beam-column structures, roof trusses Solids or models of structures, thin shells, grid structures, etc. [0003] The purpose of the structural static test is...
