Aiming at possibility for truck of weighing whenever and wherever

weighing system onboard installation is proposed.System interference factors and the overall design plan is elaborated

design scheme of system hardware and software is mainly introduced.Experimental results show that the onboard weighing system using AT89C52 as microprocessor is easy to operate

low cost and has high precision.Based on this technology

cargo weight of truck can be accurately measured wherever.The technology plays an important role in transportation of goods industry

such as environmental sanitation

logistics

coal mine and so on.
