Embodiment Construction
[0039]In the multi-channel isolated high-speed intelligent transceiver device of the present invention, the isolated transmission medium 4 can be optical fiber isolation, radio frequency wireless signal isolation, a combination of multi-core cable and optocoupler isolation, or a combination of multi-core cable and transformer isolation. Signals exist in different forms in different isolation transmission media, for example, laser is used in optical fiber for transmission, and magnetic field alternating signal is used in transformer isolation. The invention thoroughly solves the problem that the signal transmission wiring in the power electronic system is easily subjected to electromagnetic interference and the like, and improves the accuracy and reliability of the system.
[0040] The modules in the sending main control unit 13 and the receiving main control unit 23 of the present invention exist in the form of programmable modules, and their definitions include data conversion...
