Monitoring system of drilling machine

The invention provides a monitoring system of a drilling machine. The monitoring system comprises sensor assemblies, a controller and a server, the sensor assemblies are located at multiple positions on a machine body of the drilling machine, the sensor assemblies are used for obtaining parameter information of the drilling machine, and the parameter information at least comprises one of pressure information, inclination angle information and liquid level information. The pressure information is the pressure acting on a drill rod in the drilling process, the inclination angle information is the inclination angle of a drilling machine, and the liquid level information is the oil level information of a hydraulic system; the controller is electrically connected with the sensor assemblies, and the controller is used for receiving parameter information collected by the sensor assemblies; the server is in communication connection with the controller, and the server is used for receiving the parameter information se
