Background

The road facilities and bridges are protected, and the important thing is to control the total weight and the axle weight of the vehicles on the road, wherein the total weight of the vehicles is not more than 55 tons, and the single axle weight is not more than 15 tons. The highway department establishes an overrun measurement point at the highway entrance. The weighing of the load-carrying vehicle is realized by arranging a weighing lane at an entrance of a highway, so that the load-carrying vehicle can be weighed once and can be released to a high speed after being qualified. Due to manufacturing and transportation constraints, the width of a single axle weight scale is only 1.6-1.8 meters. Looking up the national highway standard, the speed is less than 60 kilometers per hour, and the width of a single lane is 3.5 meters; the speed is more than 60 km/h, and the width of a single lane is 3.75 meters. Obviously, a single axle weight scale is not enough in length of 1.8 meters, and two axle weight scales are transversely arranged in parallel to be qualified for lane weighing. The axle load scale (patent number 202020597989x) of two stopper windows of four sensor windows adopts inside prism spacing, does not have evagination spacing, does not have the clearance between weighing platform and the weighing platform. Two axle weight scales with four sensor windows and two limiter windows are arranged in parallel to weigh a wide axle group scale, and the total width of the weighing platform is more than 3.75 meters. The wide axle group scale solves the problem of dynamic weighing of the highway truck across the lane. The dynamic weighing early warning prevents the heavy load of the lorry from going on the road, improves the safety protection of the expressway, and improves the communication efficiency of the expressway.

The ground induction coil is arranged in the middle of the lane, and when the vehicle covers the ground induction coil; due to the metal characteristics of the vehicle, the ground induction coil encounters large-area metal to generate electromagnetic induction; the ground induction coil induces the arrival of a vehicle and transmits a vehicle outcrop signal to the MCU minimum system; the MCU minimum system starts the license plate snapshot machine to start the license plate snapshot machine and the weighing system, and the license plate number of the vehicle is snapshot; the vehicle continues to move forward, the front wheel of the vehicle presses the weighing platform of the wide axle weight scale, and the wide axle weight scale obtains the axle weight of the first axle of the vehicle. After analog-to-digital conversion, transmitting the data to the MCU minimum system; the vehicle continues to move forward, the MCU minimum system accumulates the first axle weight, the first axle weight plus the second axle weight plus the third axle weight, the tail part of the vehicle leaves the ground induction coil, the ground induction coil outputs zero, namely a vehicle tail sweeping signal, the rear wheel of the vehicle presses the weighing platform of the wide axle weight scale, and the MCU minimum system accumulates the total weight of the vehicle. And the MCU minimum system judges that the total weight of the vehicle is normal and the axle weight is normal, and sends the license plate number of the vehicle and the total weight of the vehicle to the upper computer through a wireless network. If the MCU minimum system judges that the total weight or the axle weight of the vehicle is overweight, the license plate number of the vehicle and the overweight early warning information of the vehicle are sent to an upper computer for emergency treatment through a wireless network.

The utility model discloses an useful part is, and broad width axle weight scale spanes the whole lane of weighing, is fit for the ground induction coil, and dynamic weighing reduces the time of weighing, and the vehicle license plate of clapping simultaneously accurately weighs, and overweight early warning prevents that overweight car from going on the road, protects highway facility safety. The wide axle load scale is suitable for being installed on a highway truck lane or an entrance ramp, is unattended, protects the safety of highway facilities and improves the passing efficiency of the highway.
