The invention provides a multichannel remote controller, including several transmitters and several receivers. The transmitter includes: instruction select switch, ID select switch, signal sampling control and holding module, ID selector, clock generator module, radio emitting circuit, and output control module, modulating continuous data frames into a signal with a certain timing sequence structure; transmit logic control module, and further including coding and data frame assembling parts. The receiver includes: receive logic control module, radio receiving circuit, ID select switch, ID selector, driving circuit, receive logic control module, and further including decoding part, checking part and ID comparing part. It uses a single carrier wave, transmits and receives in no need of many circuit structures, and designs that all the channels use different transmit timing sequences and ID, omitting synchronous operation and further simplifying the structure.
