Abstract:
1. An elevator car position detection system, comprising: a sensor stripe mounted on a sidewall of an elevator shaft; an activation device mounted on an elevator car movable in the elevator shaft relative to said sensor stripe and positioned to act on a portion of said sensor stripe adjacent to the elevator car; and a control wherein said sensor stripe includes a feed line having an end connected to said control, a resistor line having an end connected to said control, and a plurality of sensors spaced along said sensor stripe and each connected between said resistor line and said feed line, wherein each of said sensors, when actuated by said actuation device, creates a local electrical connection between said feed line and said resistor line to modify a resulting resistance between said end of said resistor line and said end of said feed line representing a position of the elevator car in the elevator shaft.
