A Portable Type of Device for Detecting the Overload and Unbalanced Load of Railway Freight Car

In order to effectively prevent the overload,unbalanced load and the unbalanced weight of the freight train at the loading station,aportable and fast installation device is developed for detecting the overload and unbalanced load of railway freight car.The hardware of the detection device comprises of the load-bearing structure,high-precision sensors,the host computer,high-speed data display and storage systems.The software of the device consists of such modules as parameter setting,self-checking,data acquisition,processing,display,query and transmission,etc.When the wheels run on the rail that is equipped with the load-bearing structure,the gravity bearing by the measurement block is converted into a group of detection signals.The detection signals are converted into the digital signals through the analogue signal processor and the A/D converter and then transmitted to the data processor unit of the host computer.Finally,the detection result can be obtained through data operation.The detection results,such as the total weight,overload,unbalanced load,and unbalanced weight of the vehicle can either be display on the LCD or stored in the disc memory.The detection device is currently installed and used in Qingbaijiang Station,and is in good operation condition.
