The invention provides a main machine and auxiliary machine interlock control device of a compressor. The main machine and auxiliary machine interlock control device comprises a main machine and an auxiliary machine oil pump and is characterized in that the power supply loop of each of the main machine and the auxiliary machine oil pump is provided with a first control power module and a second control power module which are connected with a DCS controller; the DCS controllers are connected with an auxiliary machine oil pump control device and a main machine control device. The main machine and auxiliary machine interlock control device has the advantages that after the auxiliary machine oil pump and the main machine are subjected to interlock control, oil pressure can be controlled in a certain range, control can be performed according to whether the main machine carries an oil pump or not, and the compressor is protected effectively; communication information transmission between thedevice and the DCS can b
