The invention relates to the technical field of medical equipment, in particular to a dental comprehensive treatment chair control system. The control system comprises execution mechanisms, a user interface, a detection mechanism, a manual control mechanism, a main controller, a relay control circuit, an alarm circuit, a bus and a power supply module. According to the dental comprehensive treatment chair control system provided by the invention, a user can realize control on each function only through the user interface, and the control command of each execution mechanism is automatically generated by the control system through user operation, so that the control system is simple to operate and high in automation degree; and the detection mechanism detects operating data and operating results of the execution mechanisms, so that high man-machine interaction capability is achieved.
