Alternating current charging plug-and-play matching method and device and charging operation platform

The invention provides an alternating current charging plug-and-play matching method and device and a charging operation platform, and relates to the technical field of vehicle charging. The alternating current charging plug-and-play matching method comprises the steps that a charging operation platform issues a random authentication code to a charging vehicle, and the charging vehicle decodes the random authentication code according to a clock pulse coding rule; the charging operation platform receives the vehicle identification number of the charging vehicle and the decoded random authentication code; and after the charging operation platform verifies the uploaded information successfully, the charging vehicle is charged. Verification of the platform, the vehicle and the pile is added, and one-to-one matching of the vehicle and the pile is realized through information transmission of a physical link; transformation of a clock pulse signal coding rule is adopted to realize transmission of a verification code
