The invention provides a design scheme of three-code double-wave emission, and belongs to the technical field of electronic engineering. The design scheme mainly comprises a three-code double-wave battery supply, a three-code double-wave button switch, a three-code double-wave electronic oscillating circuit switch, a three-code double-wave one-wave electronic switch, a three-code double-wave one-wave oscillating circuit switch, a three-code double-wave one-wave one-code electronic switch, a three-code double-wave one-wave two-code electronic switch, a three-code double-wave one-wave one-coded electronic switch, a three-code double-wave one-wave two-coded electronic switch, a three-code double-wave one-wave double-code or gate output circuit, a three-code double-wave one-wave double-code emission electronic circuit, a three-code double-wave two-wave electronic switch, a three-code double-wave two-wave three-coded electronic circuit, and a three-code double-wave two-wave three-code emission electronic circuit. Two types of different carriers and three types of different coded signals can be used alternately during emission to realize remote control emission of a control target to the outside, a central lock is automatically locked after all car doors are closed, and an alarm system is automatically put into use by matching with a device, so that the design scheme is convenient and has a strong modern sense. The safety factor of an automobile is effectively improved.
