Roller guide mounted elevator monitoring systems

An elevator system comprising:

• an elevator car arranged to travel on a guide rail through an elevator shaft;
• a roller guide mounted to an exterior of the elevator car;
• a roller supported on a frame of the roller guide, the roller configured to engage with and rotate along the guide rail and limit movement of the elevator car in a first direction that is normal to a direction of travel of the elevator car;
• and
• a motion state sensing assembly mounted to the roller guide and configured to measure a motion state of the elevator car within the elevator shaft, wherein the motion state sensing assembly comprises:
• an optical target located on the roller;
• a printed circuit board having an optical encoder device and a processor mounted thereto, wherein the optical encoder device and the processor are electrically connected, and wherein the optical encoder device is arranged to direct optical energy toward the optical target and detect a response of the directed optical energy;
• a sensor housing mounted to the roller guide, wherein the optical encoder device is arranged within the sensor housing;
• and
• a communication assembly in communication with the processor and an elevator controller, wherein the processor is configured to communicate data from the processor to the elevator controller using the communication assembly.
