A system and a method for detecting position and controlling speed of an elevator cabin

A method 200 for the operation of a system for detecting the position and controlling the speed of an elevator cabin, wherein the method 200 comprises:

• reading and transmitting, by a plurality of light detection and ranging sensors, distance of the elevator cabin from at least one of a ground and a topmost position of the elevator;
• 202
• reading and transmitting, by a plurality of light detection and ranging sensors, the speed of the elevator cabin by reading the distance travelled per unit of time;
• 204
• detecting, by a shaft controller, a position of the elevator cabin by receiving the distance of the elevator cabin read by the plurality of light detection and ranging sensors by measuring the distance from the ground to floor of the elevator cabin and from the topmost position of the elevator to a ceiling of the elevator cabin;
• 206
• detecting, by the shaft controller, an over speeding condition when the speed of the elevator cabin received from the plurality of light detection and ranging sensors is above a safe threshold speed;
• 208 and
• controlling, by the shaft controller, the speed of the elevator cabin by activating and deactivating a speed control unit upon detection of the over speed condition. 210

A pneumatic vacuum elevator 300 comprising:

• an external cylinder assembly 310 comprising an elevator cabin 102 inserted therein, wherein the external cylinder assembly 310 comprises a plurality of cylinders coupled using a base ring assembly 311 and a band ring assembly 312;
• a guide rail pillar 313 mechanically coupled to the elevator cabin 102, wherein the guide rail pillar 313 is disposed at the external cylinder assembly 310, wherein the guide rail pillar 313 is configured to guide an actuation of the elevator cabin 102;
• a polycarbonate sheet 314 configured to cover the external cylinder assembly 310, wherein the polycarbonate sheet 314 and the external cylinder assembly 310 is coupled using a first locking device and a second locking device, wherein the first locking device is configured to lock an air gap between the polycarbonate sheet 314, the base ring assembly 311 and the external cylinder assembly 310 and the second locking device is configured to lock air gap between the polycarbonate sheet 314 and the guide rail pillar 313;
• a seal assembly 315 adapted to fit over a top portion of the elevator cabin 102, wherein the seal assembly 315 is configured to seal the elevator cabin 102 to reduce vibrations during upward and downward movement of the elevator cabin 102,
• wherein the seal assembly 315 comprises a depressurizing system configured to prevent the elevator cabin 102 from coming into force contact with the external cylinder assembly during upward movement and contribute to safety of an elevator operation;
• and
• a plurality of light detection and ranging sensors 104 positioned at a ceiling 106 and at a floor 108 of the elevator, facing towards an elevator cabin 102, wherein the plurality of light detection and ranging sensors 104 is configured to:
• read and transmit distance of the elevator cabin 102 from at least one of a ground and a topmost position of the elevator;
• and
• read and transmit the speed of the elevator cabin 102 by reading the distance travelled per unit of time;
• and
• a shaft controller 110 operatively coupled with the plurality of light detection and ranging sensors 104, wherein the shaft controller 110 is configured to:
• detect a position of the elevator cabin 102 by receiving the distance of the elevator cabin 102 read by the plurality of light detection and ranging sensors 104, wherein the position is detected by measuring the distance from the ground to floor 108 of the elevator cabin 102 and from the topmost position of the elevator to a ceiling 106 of the elevator cabin 102;
• detect an overspeed condition when the speed of the elevator cabin 102 received from the plurality of light detection and ranging sensors 104 is above a safe threshold speed;
• and
• controls the speed of the elevator cabin 102 by activating and deactivating a speed control unit 112 upon detection of the overspeed condition.
