Online unmanned helicopter monitoring system

The invention provides an online unmanned helicopter monitoring system. The system comprises an airborne communication?device, a ground communication?control device, a sensor, a collector?and?an analyzer. According to the main working principle, the sensor sends original?sensing signals to the collector; the collector converts the sensing signals into electrical signals and sends the electrical signals to the analyzer; and the analyzer carries out calculation via a rapid?analysis formula to obtain a result, compares the result with a preset limit value and judges whether the result needs to be sent to the ground communication?control device via the airborne communication?device. According to the online monitoring system, the flight state of the unmanned helicopter can be mastered in real time by a ground operator, great convenience is brought to maintenance of the helicopter, a special?data?analysis way enables state information of the parts to be extracted from the background noise, the needed information is
