摘要： A boom extension monitoring system is provided that uses a combination of sensors to determine an absolute location and a relative location of the boom. As the boom extends or retracts, the monitoring system can determine the absolute location of the boom as the sum of the absolute at relative distances. These distances can be obtained through a combination of a grid, low-resolution sensors, high-resolution sensors, counters, processors, and other components according to various embodiments described herein. A process to obtain the total boom extension of multiple telescoping beams by monitoring the extension of a single beam element is also described.

摘要： In a method for determining the elongation of segments of a chain of a chain drive during operation, a plurality of measured values is determined at different positions of the chain. A plurality of length values is determined from the plurality of measured values and a position of the segments of the chain is determined. The length values are assigned to the segments of the chain, with the length of the segments of the chain being smaller than the length of the chain.

摘要： A steering device for a vehicle includes a steering rod and at least one drive unit, wherein the steering rod can be displaced along its longitudinal extent by the drive unit. The steering device also includes at least one first sensor device for determining a displacement position of the steering rod. The steering rod, as seen along its longitudinal extent, exhibits at least one change in its cross section, in particular diameter, wherein the first sensor device is designed to sense the change.

摘要： The invention discloses a method for vehicle classification using multiple geomagnetic sensors, which mainly solves the problems of high cost, complex processing process and difficulty in large-scale deployment of the existing vehicle classification methods. The method comprises the following steps: sequentially deploying N geomagnetic sensors on a road side at equal intervals d, each of the geomagnetic sensors respectively collecting magnetic field data around same, respectively transmitting the magnetic field data to a data processing module for storage, and judging whether a vehicle passes over a detection range of the sensors or not according to the data; calculating a time difference obtained when the vehicle passes by two adjacent sensors among N sensors, and calculating the vehicle speed and the vehicle magnetic length according to the time difference; setting a vehicle magnetic length double-threshold value and a Z axis magnetic field strength threshold value, acquiring Z axis geomagnetic data and the magnetic length that the vehicle passes by, comparing the Z axis geomagnetic data and the magnetic length that the vehicle passes by with the set threshold value, and acquiring a judged vehicle type result. According to the invention, the vehicle type information of the vehicle passing by can be accurately acquired, the reliability is high, the cost is low, large-scale deployment is easy to realize, and the method can be used for highway intellectualization.

摘要： 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. By arranging only one magnet and one set of circuitry mechanical elements to sense a position of the gear shaft, the sensing apparatus according to the present disclosure effectively implements detection of the neutral gear position and the reverse gear position of the gear shaft, which reduces the manufacturing cost and lowers the failure rate.
