The invention discloses an adaptation method of an internet based heterogeneous video conference operation and maintenance system. The method comprises steps as follows: 1), an adaptor receives required parameters of hardware equipment provided by a manufacturer; 2), a signal interface corresponding to the hardware equipment of the manufacturer is generated by the adaptor on a server of the heterogeneous video conference operation and maintenance system; 3), the adaptor calls a corresponding equipment application program interface, and a correct adaptive instance is generated on the hardware equipment provided by the manufacturer; 4), feedback result information generated in the adaptive instance is fed back to the heterogeneous video conference operation and maintenance system, the step is returned to the step 2) if the result information is failure, and the step 5) is executed if the result information is success; and 5), parameters of the signal interface are stored in an interface parameter list of the heterogeneous video conference operation and maintenance system, and corresponding equipment key values are generated; The adaptor is established to adapt to the hardware equipment provided by the manufacturer, the selection range of the hardware equipment of the manufacturer is increased, application and maintenance are convenient, and excellent application prospect is realized.
