Research On The Whole Process Condition Monitoring System For Important Mechanical Equipment Transportation

With the continuous progress of the times,the logistics and transportation industry has been booming.In the logistics transportation,accidents tend to occur due to human or unexpected reasons,especially for important mechanical equipment with high-precision requirements and high costs.Environmental factors during transportation are of great significance for the safety and quality of equipment transportation.Therefore,it is necessary to design an equipment transportation status monitoring system that can monitor the environmental parameters of important mechanical equipment transportation processes,record transportation process information,and process key parameters so as to obtain equipment status.This paper mainly investigated the entire process status monitoring terminal system and multi-source data fusion algorithm for important mechanical equipment transportation,which laid foundation for improvement of the logistics transportation safety system.In order to enable the monitoring system to comprehensively evaluate the real-time transportation status of equipment,a multi-data fusion algorithm based on weighted D-S evidence theory was proposed to fuse key motion parameters during equipment transportation.Firstly,the key motion parameters were determined based on the varying degrees of impact of different motion parameters on equipment transportation safety.Then,the weight of the key motion parameters was calculated using the structural entropy weight method to form a weight vector.According to relevant industry standards,the technical indicators of the key parameters were defined.Finally,the calculation process of the weighted multi-data fusion algorithm based on the key motion parameters was explained,and equipment transportation status evaluation rules were developed.Based on the functional scheme of the important mechanical equipment status monitoring system,the software and hardware of the entire transportation process status monitoring system for important mechanical equipment were designed using STM32F103ZET6 as the main control chip.The specific functions consist of acceleration monitoring,attitude angle monitoring,GPS positioning,clock timing,and GSM wireless communication.The hardware circuit mainly consists of motion monitoring module,positioning module,GSM communication module,storage module,battery-level monitoring module,power management module,etc.Based on the hardware circuit schematic,a PCB design was conducted.In the software design of the monitoring system,based on the system functions,the main program was first designed and written.Furthermore,the functional sub module programs were designed and written in a modular manner.Finally,based on the monitoring system for the entire transportation process of important mechanical equipment,experiments were performed on the designed hardware system,software programs,and multiple-data fusion algorithms involved to verify the feasibility and effectiveness of the monitoring system’s various functions and algorithms.As shown by experimental results,the monitoring system can not only output correct,accurate,and effective equipment transportation status results through a fusion algorithm based on weighted D-S evidence theory,but also fully store effective key parameters and stably send GPS coordinates,time,and equipment transportation status via the GSM communication module.
