The invention discloses a primary and standby switching control method used for a base station power and based on the miniature telecommunication computing frame standard, and provides a specific primary and standby switching control proposal. In the method, the primary and standby switching instruction is transmitted to a primary power supply and a standby power supply on the loading plate managing controller of a communicating center plate of the loading plate network in the miniature telecommunication computing frame system, the power supply channel power supplying state of the primary power supply is enquired, the primary channel is obtained, then the on off switch and the inductive switch of the standby power supply channel are powered on, and the inductive switch of the primary channel is powered off; the PM_OK# and the standby power supply can be switched into a new primary power supply through the primary power supply, the primary power supply is switched into a new standby power supply, and thus the primary and standby switching is completed. According to the proposal of the invention, the power output load can be alternately born by the power supply, therefore, the service life of the power supply is prolonged.
