Problems solved by technology
[0003] As the building gets higher and higher, the power supply cable in the elevator will become longer and longer. The weight of the power supply cable of the elevator with more than 20 floors is close to one-third of the total weight of the car. The increase in weight must increase the load of the hoist for lifting and lowering; this will increase the consumption of electric energy and further increase the operating cost of the elevator in the building

The invention provides an elevator car power supply system and a method. The power supply system comprises a control device, a transmitting device, a receiving device, a transmitting power supply anda receiving power supply. The receiving power supply is used for supplying power for an elevator car; the receiving device is connected with the receiving power supply, is arranged on an outer wall ofan elevator car, and is used for receiving electric energy transmitted by the transmitting device and supplying the electric energy to the receiving power supply and / or the elevator car; the transmitting power supply outputs the electric energy to the transmitting device; the transmitting device is connected with the transmitting power supply and is arranged on an inner wall of an elevator shaft;the transmitting device and the receiving device form an electric field coupling channel used for outputting the electric energy outputted by the transmitting power supply to the receiving device; and the control device is arranged between the transmitting device and the transmitting power supply, and is used for acquiring a position of the elevator car, and controlling connection or disconnection between the transmitting device and the transmitting power supply according to the position of the elevator car.
Description
technical field [0001] The invention relates to the field of elevator power supply, in particular to an elevator car power supply system and method. Background technique [0002] At present, the power supply of the elevator car is directly connected to the power distribution equipment on the ground floor or top floor of the building by cables. The power consumption of the elevator car includes the power supply of air conditioners, ventilation equipment, display screens and communication equipment; for this reason, for the safety of the elevator For effective power supply, the cost of cables is inevitably relatively high. At the same time, in view of the fact that the current elevator car power supply is connected by cable, that is, the elevator car is connected to the power distribution equipment on the bottom or top floor of the building through cables to provide power; The elevator control device drives the winch to control the lifting motion of the car in the hoistway. ...
