The application discloses a monitoring method for a turnout opening position, a turnout system and a medium, wherein the monitoring method comprises the following steps: presetting a reference position and an opening position of a turnout; setting a preset distance interval based on the reference position and the opening position; acquiring a real-time distance between a rotatable part of the turnout and the reference position in real time; judging whether the real-time distance is within the preset distance interval; and outputting an indication signal of the opening position if the real-time distance is within the preset distance interval. The monitoring method for the turnout opening position provided by the application can acquire the distance between the rotatable part of the turnout and the reference position in real time, judge whether the turnout is at the opening position through the distance, and then output a signal outward, so that the state of the turnout is judged through the signal, the collection of the turnout position is more reliable, and the reliability and safety of the system are improved.

The application discloses a kind of helicopter formation flight dispersing guiding method.For the position of three helicopter formation, distance interval and distance interval requirement after air dispersing formation at a certain time, based on kinematic equation and plane geometry principle, wingman S-shaped maneuver dispersing guiding model is established in two-dimensional plane, the flight path point and flight parameter of wingman air maneuver dispersing are calculated by comprehensively considering the characteristics of helicopter formation flight and dispersing formation requirement, so that the should fly elements sent by ground command post air guiding are obtained.The method overcomes the defects of slow artificial estimation and low precision adjustment by experience, has the advantages of high precision, good real-time, computer programming easy to realize, etc., can meet the requirements of navigation solution precision and effectiveness of ground tower command task, can reduce the air guiding operation burden of commander, improve the degree of automation of command system.The method is especially suitable for the application of helicopter command system to formation flight command guiding.

The invention provides a conflict detection method and device for aircrafts, electronic equipment and a non-instantaneous computer readable storage medium, and is applied to a control center, and the method comprises the steps: obtaining flight data of a plurality of aircrafts; calculating a distance interval of any two aircrafts in the plurality of aircrafts at any time point and a time interval of any two aircrafts at any spatial point in a preset time period; when the distance interval is smaller than a preset distance interval threshold value and the time interval is smaller than a preset time interval threshold value, constructing a conflict range of any two aircrafts; and carrying out clustering analysis on the plurality of aircrafts by utilizing the conflict range so as to divide the aircrafts with conflicts into the same cluster. According to the embodiment, the conflict range of any two aircrafts is constructed through the control center according to the preset time interval threshold value and the distance interval threshold value, so that the aircrafts with conflicts are divided into the same cluster, and a data basis is provided for subsequent conflict resolution.
