Truck Parking Cheating Detection System of the Truck Scale Using the Voltage Waveform Analysis.

Abstract: Truck scale is an important weighing instrument. The truck parking cheating method is one of the truck scales cheating method and can lead to large economic losses to the enterprise. A new truck parking cheating detection method based on the voltage waveform analysis is brought out in this paper. According to the output voltage signal waveform of the weighing transducer, if the turning point number of the output voltage is different with the truck axles, the truck parking cheating method exists. Based on the principle, the truck parking cheating detection system is designed. The instrument is using 8031 as the MCU and can be transmitted the voltage signal to the control computer. Experimental data show that the detection system can on-time detects the truck parking cheating method. [Copyright &y& Elsevier]
