Description
Technical field
The utility model relates to Wireless Laser Communication Technology device technique field, specifically a kind of non-contact type photoelectricity slip-ring device.
Background technology
Electric sliding ring relies on brush to contact with ring wall, from the becket rotating to stationary ring transferring electric power electric current and data-signal, the morning that the technology of electric sliding ring occurs, relatively ripe, therefore be widely used, but along with requiring more and more higher to signal bandwidth, as vision signal, multi-media signal etc., electric sliding ring obviously shows potential limitation, bandwidth is low is larger weakness of electric sliding ring, in addition the clock that electrical interconnection itself exists is crooked, the shortcomings such as the large and anti-interference of energy consumption is poor make electric sliding ring be only suitable for the signal that some speed are lower to transmit, for some high frequencies and high speed signal, the bit error rate of signal can significantly increase. because electric sliding ring is to rely on brush signal transmission, the quality of brush will have a strong impact on the transmission quality of signal, and the friction between brush and ring wall is that inevitably this has also limited its application in high speed centrifugation slewing. at present, study general of the prior art is only under the slow-speed of revolution, adopt traditional data acquisition equipments such as electric brush type current collector to carry out the analog signal transmission of parameter, test result error is larger, and only there is less measurement passage, can not meet compared with the parallel acquisition of multiple spot parameter, cause experimental data insufficient, thereby make the Development Level of aero-engine be subject to larger impact.
At present, in the existing application that adopts LASER Light Source to be rotated non-contact data transmission of state, data acquisition module and transport module are embedded in high-speed rotary part, system adopts multiple highly dense connectors to form multiple data acquisition modules and single light delivery module, but this spliced sandwich construction has inevitably increased the difficulty of system installation and debugging, and due to centrifugal reason causes can be very high to the quality requirement of high-density socket, synchronous signal, through high-density socket transmission, brings hidden danger can to the signal reliability in equipment high speed rotary course.
