The invention discloses a door lock control device. The door lock control device mainly comprises a door lock opening circuit and a door lock closing circuit, wherein the door lock opening circuit is formed by connecting a door lock opening signal pin of a singlechip, a first resistor, a first triode, a first relay with a door lock opening pin of an opening resistor and a door module in series sequentially; the door lock closing circuit is formed by connecting the singlechip, a second resistor, a second triode, a second relay with a door lock closing pin of a closing resistor and the door module in series sequentially; and the first relay, the second relay and the door module are grounded. The invention also discloses a door lock control system having the door lock control device. The door lock control device provided by the invention controls the door module by simulating a central switch so as to control a door lock motor; and when the door module protects and limits the door lock motor, software in the door module does not need to be modified, and thus, the door lock control device can control the door lock motor, and is simple to operate, flexible and energy-saving.
