Abstract (en)
[origin: EP0722903A1] 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.
