The invention discloses a self-adaptation wireless charging power source system for an elevator cab. The self-adaptation wireless charging power source system comprises wireless electric energy transmitting devices located on an elevator shaft, wireless electric energy receiving devices located on the cab and wireless charging control devices. On the one hand, a power supply grid supplies power to the wireless electric energy transmitting devices through the wireless charging control devices; on the other hand, the wireless charging control devices adjust the resonant frequencies and the voltage values of the wireless electric energy receiving devices and the wireless electric energy transmitting device closest to the wireless electric energy receiving devices according to the distance between the wireless electric energy transmitting devices and the wireless electric energy receiving devices and energy consumption requirement information of the elevator cab in a self-adaptation manner so that the wireless electric energy transmitting device closest to the wireless electric energy receiving devices can supply electric energy to the wireless electric energy receiving devices. According to the self-adaptation wireless charging power source system, the wireless electric energy transmission efficiency in the cab running process is greatly improved, the requirement for cable-free and light-cable elevator cab energy storage equipment is lowered, and application and popularization of cable-free and light-cable elevators are promoted.
Description
Technical field [0001] The invention relates to the technical field of elevator power supplies, in particular to an elevator car adaptive wireless charging power supply system. Background technique [0002] Generally, the elevator power supply supplies power to the lighting devices, fans, operating doors, door machines, control and display equipment and other equipment in the elevator car through the power supply cable that rises and lowers with the car. However, as the height of the elevator continues to increase, the length of the cable required increases, thereby increasing the installation cost of the elevator; in addition, the building will shake to a certain extent due to reasons such as blowing, and then contact or entangle the hoistway equipment Circumstances, and easily interfere with other control signals. [0003] In order to avoid the occurrence of the above-mentioned problems, a technology of supplying power to the elevator car in a non-cable manner or light-weight ca...
