The invention discloses an air-cooling diesel oil AC set control system for a communication base station. The air-cooling diesel oil AC set control system comprises a controller, an electronic speed regulator and a bi-power-supply switching apparatus, wherein the controller is connected with the electronic speed regulator, the controller is connected with a first current transformer on the live wire of a commercial power supply, the input end of the bi-power-supply switching apparatus is connected to a commercial power access line and a diesel oil AC set access line through a bi-power-supply change-over switch, the output end of the bi-power-supply switching apparatus is connected with a load bus, a second current transformer is arranged between the load bus and the bi-power-supply switching apparatus, and the bi-power-supply switching apparatus is also connected with the controller. Remote switching between an air-cooling diesel oil AC set and the commercial power can be realized more conveniently and accurately, thereby ensuring safe operation of the communication base station.
