Method and device for determining the state of a rail stretch |
摘要 |
A method and a device for determining the state of a rail stretch utilize a receiver that is moved along the rail stretch to receive radio signals transmitted by at least three transmitters mounted in the elevator shaft. Spacing data is determined from the radio signals and is compared by an evaluating unit with reference data of the spacing to generate a result with respect to the state of the rail stretch. The positions of rail fastenings, connecting straps and shaft doors can be detected by additional sensors also moved along the rail stretch and are represented in a correction protocol to permit an efficient adjusting of the rail stretch.
