The Research Of Wireless Portable Vehicle Weigh-In-Motion System Based On Android

At present, the number is not in accordance with the rules and regulations for transport vehicles growing, transportation basic facilities because of this undesirable phenomenon by some damage, traffic safety provocation, but to a certain extent their personal lives as well as endangering their property safety. Up to now, domestic monitoring method beyond its rated load transport vehicles is limited, there are two kinds of monitoring static and dynamic monitoring of the load detection mode, most established highway inspection station is fixed, the drawback is that illegal vehicles in order to avoid fines can choose to bypass stations to avoid so as not to carry out the relevant checks, which gives overloading caused some opportunities. Currently, the Android-based wireless portable vehicle dynamic weighing system research is to improve the instruments used in the past to bring all aspects of the inconveniences, such as the operation is not approachable, relatively low accuracy, such as its no longer certain adaptability.Based on its subject background and its significance, made it clear that the Android system with WIFI module applications WIM (Weight in Motion) in, followed by analysis and study of several common filtering methods to get rid of noise, according to their characteristics WIM design that matches your filtering and weighing algorithm basis. Next, the analysis of this system, the overall design, then the system is divided into two parts, namely hardware and software in two modules, the two parts will be achieved step and explain the process in detail, based in part on the acquisition cost select the MAP430, which not only has a relatively high performance, but also possesses a relatively low power consumption, converter A/D select the CS5530, its relatively high resolution, WIFI module based on the performance of selected ESP8266 module, load management system based on demand selection is equipped with Android handheld devices. Android-based WIM, law enforcement officers to apply this system may have overloaded the suspect vehicle.found in campaign checks, so to some extent, to the illegal overloading the driver played a warning, the results of actual vehicle experiment meets also requirements to meet expectations.
