Transport rail system with weighing means comprising a sensor for measuring a change of a magnetic property |
| 摘要 |
Transport rail system capable of detecting a weight of a rail vehicle, includes one or more rails, and one or more sensors for measuring a magnetic property. At least one of the sensors is adapted to measure a change of a magnetic property in order to determine a weight bearing on one or more of the rails, the change of the magnetic property being caused by stress exerted on the rail by the weight, and one or more of the sensors are adapted to measure the change of a magnetic property of the rail itself and/or that one or more of the sensors are adapted to measure the change of a magnetic property of a supporting structure of the rail. |

1. Transport rail system capable of detecting a weight of a rail vehicle, comprising:
one or more rails, and at least one sensor for measuring a magnetic property, wherein the at least one sensor is adapted to measure a change of a magnetic property in order to determine a weight bearing on one or more of the rails, the change of the magnetic property being caused by stress exerted on the rail by said weight, wherein the at least one sensor is adapted to measure the change of a magnetic property of the rail itself and/or that the at least one sensor is adapted to measure the change of a magnetic property of a supporting structure of the rail, and wherein a physical effect underlying the change of the magnetic property to be measured by the at least one sensor is an inverse magnetostrictive effect. |
