Abstract: A drive control device, which includes a control module generating an optical driver power supply control signal; a detection module detecting a working state of an optical driver according to the optical driver power supply control signal or receiving an external input signal and generating a switch control signal according to a detection result or the external input signal; and an execution module electrically connected with the detection module and powering on or off power supply on the optical driver according to the switch control signal. The powering-on and powering-off of the optical driver are flexibly controlled, the situation of increase of additional power consumption of a device for a reason that the optical driver is in a standby state for a long time is avoided.
