Dynamic intelligent detection system and method for torque wrenches based on internet of things gateway networking

Abstract

The invention discloses a dynamic intelligent detection system and method for torque wrenches based on internet of things (IOT) gateway networking. The system comprises detection terminals, a communication network and an upper computer, wherein the detection terminals are simultaneously connected with the upper computer via the communication network, and exchange information via the communication network; the communication network is of a star topology structure and comprises a plurality of interconnected IOT gateways, each IOT gateway is connected with a plurality of detection terminals, and each detection terminal at least comprises a torque acquisition unit, a signal processing unit and a processor; the detection terminals can intelligently and dynamically detect the torque wrenches to obtain detection results. The detection terminals are of a distributed architecture and can realize distributed multi-directional simultaneous detection, and simultaneously, information can be accurately acquired and transmitted via the star architecture.

Description

technical field [0001] The invention relates to a dynamic intelligent verification system and method for a torque wrench based on an Internet of Things gateway network. Background technique [0002] Torque wrench, also known as torque wrench, torque wrench, torque adjustable wrench, is a kind of wrench. According to the power source, it can be divided into: electric torque wrench, pneumatic torque wrench, hydraulic torque wrench and manual torque wrench; Stability of product quality. However, long-term use will increase the error of the wrench. At this time, it needs to be checked and adjusted. At the same time, the torque wrench also needs to be tested and calibrated before leaving the factory to ensure its accuracy. [0003] The types of devices used to test torque wrenches in the prior art are relatively single, mostly static torque test, the output of the result is single, and the output force value of the torque wrench cannot be monitored in real time. At the same tim...

AI Technical Summary

Problems solved by technology

[0003] The types of devices used to test torque wrenches in the prior art are relatively single, mostly static torque test, the output of the result is single, and the output force value of the torque wrench cannot be monitored in real time. At the same time, the static test after the screw is fixed may affect the tightened screw. Cause unpredictable impact; secondly, the existing dynamic torque verification mostly uses controllers such as PLC, which has slow processing speed, low sampling frequency and poor user interaction

Furthermore, the existing equipment is bulky, heavy and poor in mobility

[0004] At the same time, the existing verification is one-to-one verification, which cannot realize distributed multi-party simultaneous verification and information transmission of multi-party multi-terminal verification structure

[0005] In summary, the devices for verifying torque wrenches in the prior art have the problems of single output results, slow processing speed, low sampling frequency, poor user interaction, and inability to perform verification at multiple locations or terminals at the same time
