    Abstract: The method provides information on an elevator hoistway (1) to control an elevator. An elevator car (6) is provided to be guided in the hoistway. A readable code (3) is arranged in the hoistway. The code is read as an image. At least one pattern in the image of the code is detected. The detected pattern is compared to a reference pattern. Hoistway information is generated from the detected pattern to control the elevator. The appts. includes at least one sensor (10) to read the code. It also includes at least one device to detect the pattern. At least one computing unit evaluates the hoistway information contained in the pattern. Preferably the pattern detected includes at least one light region and one dark region. A pattern repetition distance is then derived from the spacing between the middle of dark regions. The position of the elevator car (6) is read from the repetition distance.

    Abstract: This monitoring equipment (1) for a drive control for lifts consists substantial ly of two modules, a safety circuit sensor system (2) and a motor-switching and/or brake-s witching circuit (3), wherein the monitoring of a safety circuit (4) and the consequentia l actions resulting therefrom takes place exclusively by means of electronic components wh ilst avoiding electrically conductive separating locations. By the use of electronic components, electromechanical switching elements, which have electrically conduc tive separating locations, can be dispensed with. In addition, an appreciable reducti on in the noise level is achieved, since switching noises no longer arise. This has an adv antageous effect particularly in the case of lift installations without machine room. Furt hermore, the manufacturing costs can be significantly reduced and a high security and reliabi lity of the monitoring equipment (1) can be ensured by the use of usual electronic component s.

    Abstract: The over-velocity detector uses a multi-channel light barrier (7) associated with the lift cabin and a redundant measuring rail (6) attached to the side of the lift shaft, with markings (10,13) defining a travel path (8) and a control path (9), which are scanned by the light barrier. The measuring rail may also have a safety path with markings in the form of slits or holes, the light barrier having at least 2 independent channels, positioned symmetrical to one another.

    Abstract: A method for controlling a sliding door system determines the masses and the frictional forces of all movably interconnected parts of the sliding door system. The system has a door leaf which is moved in an opening learning travel and a closing learning travel and guided without drive over respective first and second test sections. First and second energy balances are determined from the detected speed and distance travelled data of the first and second test sections respectively. The energy balances equate the kinetic energy at the beginning of a test section with the kinetic energy at the end of the test section plus the frictional energy plus the potential energy of a closing weight connected to the door leaf. The potential energy is added with a positive sign for opening travel and a negative sign for closing travel. The dynamic mass and the mean frictional force of the sliding door system can then be determined from the first and second energy balances. An apparatus for controlling the door motor in accordance with the method includes a microprocessor in a door drive with a memory for storing the speeds and distances associated with the learning travels. The microprocessor and the tachometer detect, store and process the speed and distance data, and the microprocessor determines the values for the dynamic mass and the mean frictional force and also the closing speed, which is the maximum permissible for safe operation of the door.
