Abstract: The present disclosure discloses a sensing system for sensing a position of a gear shaft. In the present disclosure, a magnet apparatus is provided on the gear shaft, where the magnet apparatus includes, along a rectilinear motion direction, a first length region magnet and a second length region magnet, the second length region magnet including a first portion and a second portion, a magnetic field of the second portion of the second length region magnet corresponding to a reverse gear position being different from that of the first length region magnet and that of the first portion of the second length region magnet. An actually induced electrical signal generated by sensing the motion of the magnet apparatus is different from a reference inductive electrical signal of a corresponding position of a reference magnet.

Abstract: The present disclosure discloses a sensing system for sensing a position of a gear shaft. The present disclosure may implement determination of whether the gear shaft is at a reverse gear position, a forward gear position or a neutral gear position by: partitioning a magnet into a first length region magnet and a second length region magnet, wherein the first length region magnet and the second length region magnet have different magnetic field directions, sensing and generating an inductive electrical signal reflecting motions of the first length region magnet and the second length region magnet; storing, by a memory unit, a first type reference signal for the first length region magnet and a second type reference signal for the second length region magnet, which are sensed by simulation; and comparing, by a processing unit, the inductive electric signal against the first type reference signal and the second type reference signal, which reflect different gear positions, respectively.

Abstract: An overpass structure with vertical interchange arrangement for crossroads includes a transverse roadway at a bottom level, a pedestrian walkway in the middle level and a longitudinal road bridge at an upper level. The vehicle roadways on and under the bridge are connected by two ramp units. The pedestrian walkway is a pedestrian platform with an interchange platform provided on top. The interchange platform is located between and connected to two roadways of opposite directions on the longitudinal road bridge in the upper level. The leftmost lane along a forward moving direction of vehicle on the bridge in the longitudinal road bridge is defined as a universal lane of the longitudinal road bridge. The rightmost lane along a forward moving direction of vehicle under the bridge in the transverse roadway is defined as a universal lane of the transverse roadway. The interchange platform is connected to four universal lanes.

Abstract: The invention provides a method and a system for sensing position of a moving object. A relatively long stroke of a moving object is divided into multiple areas. A sensing element is disposed in each area to sense a magnetic field signal when a magnet apparatus moves along with a moving object and passes through each area, and to generate a sensed signal of each area. A microcontrol unit receives sensed signals of segments and performs temperature compensation and correction on the sensed signals, then combines the sensed signal according to time and a stroke sequence to form a continuous moving-object movement signal that reflects the entire stroke.
