The system according to claim 4, further comprising a power source unit connected to the monitoring device. 6. The system according to claim 2, wherein the controller is adapted to monitor periodic communication between the master device and the slave device and to stop motion of the slave device if periodic communication is not detected. 7. The system according to claim 6 wherein the slave device includes: the plurality of drive units to drive a plurality of joints of a robot arm and a plurality of joints of a surgical instrument; andan emergency brake unit to interrupt power to be applied to the plurality of drive units, andwherein the controller controls interruption of power to be applied to the plurality of drive units using the emergency brake unit to stop the motion of the slave device. 8. The system according to claim 1, wherein the monitoring device further includes: a communication unit; anda brake signal generator to generate a brake signal to stop the motion of the slave device, andwherein the controller transmits the brake signal to the slave device via the communication unit to stop the motion of the slave device. 9. The system according to claim 1, wherein the slave device includes: the plurality of drive units to drive a plurality of joints of a robot arm and a plurality of joints of a surgical instrument;an emergency brake unit to interrupt power to be applied to the plurality of drive units; anda controller to transmit the drive signals to the plurality of drive units to operate the robot arm and the surgical instrument, andwherein the controller of the monitoring device inspects the drive signals in real time and interrupts power to be applied to the plurality of drive units via the emergency brake unit if an abnormal drive signal is detected to stop the motion of the slave device. 10. The system according to claim 9, wherein the monitoring device is located inside or outside the slave device. 11. The system according to claim 10, further comprising a power source unit connected to the monitoring device if the monitoring device is located inside the slave device. 12. A control method of a surgical robot system, the surgical robot system including a slave device, a master device and a monitoring device, the method comprising: analyzing, by the monitoring device, a control signal and drive signals, the control signal being transmitted from the master device to the slave device, and the drive signals being transmitted from the slave device to a plurality of drive units associated therewith;determining whether one or more of the control signal and the drive signals are abnormal based on the analyzing andstopping a motion of the slave device if the monitoring device detects that one or more of the control signal and the drive signals are abnormal, wherein the monitoring device includes, a signal collector configured to collect the control signal and the drive signals transmitted within the system in real time,a signal analyzer configured to analyze the control signal and the drive signals in real time to detect if any of the control signal and the drive signals are abnormal, anda controller configured to control real-time collection of the control signal and the drive signals and analysis thereof, and to stop the motion of the slave device, if the controller detects that one or more of the control signal and the drive signals are abnormal, wherein the signal collector, the signal analyzer and the controller of the monitoring device are electrically connected together. 13. The method according to claim 12, wherein judgment of whether the determining includes: determining whether one or more of the control signal and the drive signals are normal signals or abnormal signals; anddetermining whether the master device and the slave device periodically communicate with each other. 14. The method according to claim 12, wherein stopping of the motion of the slave device is implemented by interrupting power to be applied to one of the drive units that drives at least one joint of the slave device. 15. A monitoring device connected to a master device and a slave device or a surgical robot, the monitoring device comprising: a signal collector configured to collect a control signal and drive signals, control signal being transmitted from the master device to the slave device, and the drive signals being transmitted from the slave device to a plurality of drive units associated therewith;a signal analyzer configured to analyze the control signal and the drive signals to detect if any of the control signal and the drive signals are abnormal; anda controller configured to stop a motion of the slave device if the controller detects that one or more of the control signal and the drive signals are abnormal, wherein the signal collector, the signal analyzer and the controller of the monitoring device are electrically connected together. 16. The monitoring device according to claim 15, further comprising: a brake signal generator to generate a brake signal to stop a motion of the slave device if an abnormal signal is detected. 17. The monitoring device according to claim 16, wherein the controller of the monitoring device selectively stops a motion of the slave device according to whether it is determined a controller of the slave device has malfunctioned. 18. The monitoring device according to claim 17, wherein if it is determined the controller of the slave device has not malfunctioned, the controller of the monitoring device transmits a brake signal generated by the brake signal generator to the slave device to direct the controller of the slave device to stop the motion of the slave device. 19.
