摘要： The invention relates to a sensor module (1) for measuring axle speeds and weights of double-track vehicles which travel in a direction of travel (L) along a carriageway with two lanes (S, S'), comprising a plurality of piezoelectric strip sensors (A, B, C, D) which are arranged in a first and a second lane group (I, II). All the strip sensors (A, B, C, D) are spaced from each other in the direction of travel (L) via a secure longitudinal offset (LAD), which is greater than the maximum wheel contact length (300), and are offset from one another by between 1 cm and 15 cm in transversal direction. The sensor module (1) also has a module length (LABCD) of less than 80 cm.

摘要： The invention relates to an electronic circuit for converting a charge signal of a WIM (Weigh-in-Motion) sensor 3, that is installed in a roadway 6 and has a charge signal output and a ground output, into a voltage signal. The circuit comprises a charge amplifier having an IC1 that has a first and a second input as inputs of the sensor 3. The circuit also comprises an integrated impedance converter (IEPE) at the output to a two-core cable 5 having a voltage signal output "OUT" and a ground output "GND". According to the invention, a capacitor (Cc) is connected in series to the charge signal output "In" of the sensor 3 at the first input of the IC1 of the charge amplifier for decoupling the internal DC voltage of the circuit via the sensor 3. Furthermore, a Zener diode D is arranged between the ground output "GND" of the sensor 3 and the second input of the IC1, which diode can be fed through a resistor R1, together with a current source 8 arranged at the output side, via the two-core cable 5 in order to adjust the potential at the second input of the IC1. In particular, the ground output of the sensor is at the same potential as the ground output of the two-core cable 5.

摘要： The invention relates to a method for determining the weight G of a vehicle (1) by means of at least one WIM sensor (5) during travel on a road section (3) of a road (4). During transit of the vehicle (1), both the wheel loads F
i (t) of all wheels (2) or double wheels i and the speed vi(t) of the vehicle (1) on this road section (3) are detected throughout the entire transit as functions of time, and the speeds vi(t) and their variations over time are used as weighting factors for the simultaneously determined wheel loads Fi(t) in the evaluation of the data in order to determine the weight G. According to the invention, the WIM sensor (5) is narrower in the direction of travel than the length (14) of the contact area of a wheel.

摘要： The invention relates to an oblong hollow profile (1) for a WIM (weight-in-motion) sensor, comprising two force-transmission plates (2) arranged parallel to each other and a tube (3) arranged between said plates (2), which is integrally formed with the plates (2) and forms a hollow space (5). Two supports (6) that are arranged opposite one another are formed inside the hollow space (5), each one extending away from a respective plate (2) and between which a measuring element (7) can be received centrally in the tube (3) under preload. The tube (3) comprises two tube segments (8) designed to be mirror-symmetrical with respect to each other, which join the plates (2) together and on the inside adjoin the hollow space (5). According to the invention the wall thickness (9) of each tube segment (8) has at least two relatively thin regions (10) and a relatively thick region (11) therebetween.

摘要： The invention relates to a method for calibrating a WIM (Weigh In Motion) sensor (2) built into a road (1), the sensor being suitable for determining the dynamic and/or static weight of a vehicle (3) as it is passing over the WIM sensor (2). According to the invention, a calibrating vehicle (3) that is fitted with at least one measuring wheel (4) passes over the WIM sensor (2). During travel, the dynamic wheel force (5) on the road (1) and on the WIM sensor (2) is measured dependent on time or location directly at said measuring wheel (4) and conveyed to an evaluating unit (7). In addition, at the same time WIM signal data (6) are measured at the WIM sensor (2) and also conveyed to the evaluating unit (7). The wheel force data (5) is synchronised with the WIM signal data (6) and on the basis of a comparison of the wheel force data (5) with the WIM signal data (6), a calibrating function (8) is determined, which is used for calibrating the WIM sensor (2).
