Abstract: A power distribution and vehicle self-learning-based truck overload identification method, comprising: acquiring load identification data of a vehicle; calculating AOP values and STP values according to the load identification data of the vehicle; according to a plurality of sets of AOP values and STP values in a standard full-load state, constructing a power distribution curve of the vehicle in the standard full-load state; and comparing an AOP value during an actual operation process to a corresponding AOP value in the power distribution curve in the standard full-load state, and according to a comparison result, identifying whether the vehicle is overloaded. The method can show the operating states of overloaded vehicles in the road network in real time to provide convenience for oversize and overloading management. Loads of vehicles operating in the road network can be monitored in real time without additional equipment, thus improving the scope of overload identification.

Abstract: A fence column and a fence system, wherein the fence column is adapted for fixing a protection barrier extending both horizontally and vertically. The fence column comprises a first main body and a second main body fixedly connected onto the first main body. The first main body is provided with a connecting surface on one side where the first main body is connected with the second main body. The connecting surface is vertically arranged with multiple first positioning members. Multiple second positioning members corresponding to the multiple first positioning members are vertically arranged on the second main body; the first positioning members pass through the protection barrier to fix with the second positioning members, or vise versa; the protection barrier is fixed between the first main body and the second main body.

Abstract: A pre-leveled, integrated mosaic sheet consists of a flat, rigid supporting board having an array of uniformly spaced small holes for coupling tesserae to a target wall, wherein the tesserae are pre-patterned and attached to the supporting board's front surface, each of which covering at least one of the small holes.
