The invention provides a double speed rotary transformer wiring automatic detection device suitable for a photoelectric rotary table and a double speed rotary transformer wiring automatic detection method thereof. Firstly all the wiring sequence combinations are enumerated by using an enumeration method, and then an original input wire sequence is switched to a new wiring combination of the enumerated wiring combinations by changing the address code of a signal switching module; and then the wiring combination is solved by a shaft angle solving module, and the solving result is transmitted back to a master control module. After clicking a detection start button to start automatic detection, a motor matched with the rotary transformer in the rotary table drives the rotary table to uniformly rotate after being powered on, and a shaft angle judgment module performs judgment according to the shaft angle data inputted by the master control module. With application of the device and the method, the correct wire sequence can be automatically detected so that the repeated work of present manual welding backwinding verification can be solved, the work efficiency of the adjusting process can be enhanced and thus use is reliable.
