technical field [0001] The invention relates to the field of wireless power supply and information transmission, in particular to a communication mechanism for realizing wireless power supply and photoelectric transmission by using a tank-type magnetic core. Background technique [0002] The existing wireless power supply mechanism for laser distance measuring devices generally adopts two methods to realize the transmission of power and information between the fixed component and the rotating component. One is to use a slip ring to realize the transmission of power and information between the fixed component and the rotating component. Transmission, because the information transmission requires relatively high contact with the slip ring, so the machining accuracy and assembly accuracy of the slip ring are required to be high, otherwise it will lead to wrong information transmission, unstable work, and short life. Another way is to use wireless to transmit power and informati...

[0002] The existing wireless power supply mechanism for laser distance measuring devices generally adopts two methods to realize the transmission of power and information between the fixed component and the rotating component. One is to use a slip ring to realize the transmission of power and information between the fixed component and the rotating component. Transmission, because information transmission has relatively high contact requirements for slip rings, so the machining accuracy and assembly accuracy of slip rings are required to be high, otherwise it will lead to information transmission errors, unstable work, and short life

Another way is to use wireless to transmit power and information, but the traditional wireless way uses internal and external inductance or upper and lower plane inductance to transmit power, which is inefficient, large in size, and susceptible to electromagnetic interference, so it is greatly reduced. Improve the efficiency of power transmission and the efficiency and correctness of data transmission
