Abstract: In order to ease the labor intensity of net culture fishing and net maintenance, MCU and wireless remote control technology are adopted to realize the automatic control of net lifting. This paper introduces the main performance characteristics of PT2262 encoder and PIC16C57 MCU, elaborates the working principle, circuit design and software programming technology of the wireless remote control transmitter based on the former, and those of the receiving controller based on the latter. The wireless transmitter can control not only single wireless receiving decoding controller but also multiple wireless receiving decoding controllers. The system is user-friendly, stable and reliable, with functions such as positive and negative control, self-locking and interlocking, as well as self-learning, etc..
