Finally, it has proven to be disadvantageous that the driveway castables can detach from the force introduction flange due to strong effects (as they occur when braking the vehicle), so that the sensor device may no longer be able to correctly detect the movement of a vehicle driving on the driveway. Gravity, which in turn impairs the usability of the sensor unit

Embodiment Construction
[0023] figure 1 , figure 2 , Figure 5 to Figure 8 Two preferred embodiments of the sensor device 1 according to the invention are shown before and after installation in a roadway. The sensor device 1 has an extension along a longitudinal direction L, a transverse direction Q and a vertical direction V. As shown in FIG. These three directions are perpendicular to each other. The extension of the sensor device 1 along the longitudinal direction L is significantly greater than the extension along the transverse direction Q and along the vertical direction V. Preferably, the sensor device has a length along the longitudinal direction L of 1000 mm or more, whereas it has a width along the transverse direction Q of about 30 mm to 50 mm and a height along the vertical direction of 20 mm to 70 mm. The longitudinal direction L and the transverse direction Q span a longitudinal plane. The vertical direction V and the longitudinal direction L span a vertical plane. The transverse...

The invention relates to a sensor device (1) for installation in a lane; wherein the sensor device (1) comprises a hollow profile (2) and a piezoelectric measuring system (3); wherein the hollow profile (2) comprises a chamber and the piezoelectric measuring system (3) is arranged in mechanical contact with the hollow profile (2) in the chamber; wherein the hollow profile (2) comprises an externalforce introduction area (200) and the hollow profile (2) directs a gravity force acting on the force introduction area (200) onto the piezoelectric measuring system (3); and wherein the piezoelectricmeasuring system (3) detects an introduced gravity force and outputs electrical signals proportional to a variable of the detected gravity force; wherein the sensor device (1) comprises a partition element (4, 4', 4"), which partition element (4, 4', 4") does not direct a rolling force acting on the partition element (4, 4', 4") into the hollow profile (2); and wherein the partition element (4, 4', 4") comprises at least one distribution opening (40, 40') through which distribution opening (40, 40') bedding compound (5) can flow.
Description
technical field [0001] The invention relates to a sensor device for installation in a roadway and a method for installing the sensor device in a roadway according to the preambles of the independent claims. Background technique [0002] In road traffic, vehicles drive on lanes. To increase safety in road traffic and minimize lane damage, the number of vehicles in motion, wheel loads, axle loads, total weight, tire pressure are monitored. Sensor devices are often installed in roadways to detect the gravity of a moving vehicle. The sensor device has a piezoelectric measuring device. Each time a vehicle drives past the sensor device, the piezoelectric measuring device detects the gravitational force caused by the moving vehicle. In this case, the detection of gravity takes place so quickly that the vehicle can drive past the sensor arrangement at normal traffic speed. The piezoelectric measuring device outputs an electrical signal proportional to the detected magnitude of t...
