The invention relates to a method for remotely controlling an intelligent television, which comprises the following steps that: a network connection is established between a remote-control end and the intelligent television; the remote-control end sends a control command to the intelligent television; the intelligent television receives the control command and feeds back a response frame to the remote-control end; when the remote-control end knows that the control command is correctly executed according to the feedback response frame, the remote-control end sends a screen-transmission synchronous request to the intelligent television; the intelligent television returns a response frame which at least contains screen display content back to the remote-control end; and the remote-control end carries out displaying as a feedback frame according to the content of the returned response frame. According to the method provided by the invention, the control command is sent to the intelligent television after the network connection (such as Internet network connection) is established between the remote-control end and the intelligent television, further, the screen-transmission synchronous request is then sent to the intelligent television after a feedback result which indicates that the command is correctly executed is obtained, and thus, the real-time visualization of a control process is realized at the same time of realizing the remote control of the intelligent television.

The embodiment of the invention discloses a conflict-free track planning method, device and system based on the reachable space-time domain, which relates to the technical field of air traffic management and planning, and helps to improve the flight safety of aircraft in the four-dimensional track operation mode and reduce the controller workload. The invention includes: collecting the flight data of the aircraft in the cruising operation stage, and recording the real-time position and planned track of the aircraft in the cruising operation stage in the three-dimensional space-time coordinate system; The aircraft’s accessible space-time domain and the intruding aircraft’s oblique cylinder protection zone; the intersection of the accessible time-space domain and the intruding aircraft’s oblique cylinder protection zone is projected onto a two-dimensional plane to obtain a set of conflict diversion points; the conflict diversion point The set of is removed from the reachable space-time domain projected by the main aircraft on the two-dimensional plane, and a set of conflict-free diversion points and a conflict-free feasible diversion track can be generated. The invention is applicable to air traffic management.

The invention discloses a method for monitoring the state of a propulsion shafting system of a large ship, which specifically includes the following steps: selecting a monitoring position on a stern tube bearing; fixing an eddy current displacement sensor in a bearing groove at the monitoring position; The shaft center offset voltage signal detected at the time is transmitted to the host computer through the data acquisition box, and the host computer calculates the real-time position of the shaft center at the monitoring position according to the received signal; calculates the minimum clearance of the bearing oil film at the monitoring position; comprehensively judges the axis System running status. The present invention combines the minimum clearance of the bearing oil film at each monitoring position with the ship's navigation status signal for real-time visual display, which can intuitively and accurately display the running status of the propulsion shafting of large ships, and when the shafting fails, it can An alarm signal is issued to ensure the safe operation of the shaft system.
