Driving circuit and industrial personal computer

The utility model relates to the technical field of equipment driving, and discloses a driving circuit and an industrial personal computer, the driving circuit comprises a control module, an output optocoupler module, an input optocoupler module and a GPIO module; the control module is used for sending a first level signal to the output optocoupler module, and the output optocoupler module is used for conducting a driving loop, connected to the output optocoupler module through the GPIO module, of external equipment based on photocoupling after receiving the first level signal so as to drive the external equipment to work; the GPIO module is used for sending a second level signal fed back when external equipment works to the input optocoupler module, and the input optocoupler module is used for conducting a feedback line between the control module and the input optocoupler module based on photocoupling after receiving the second level signal. Therefore, the control module obtains a third level signal used for
