The self-destruction module can complete disintegration within 2.5 seconds, far exceeding the industry standard and reducing secondary risks.

[0024] The positioning module 150 of the embodiment of the present invention is configured to provide the position information of the beacon ball to the ground control subsystem in real time. The positioning module 150 adopts a general standardized dual-mode positioning module. The positioning module 150 supports both GPS and Beidou navigation positioning at the same time, and the output format of the positioning module 150 is NMEA0183. The ground control subsystem is configured to remotely control the airborne beacon ball subsystem, and issue command data to the airborne beacon ball subsystem to realize the control of frequency switching, time and space judgment, and self-destruction function of the airborne beacon ball subsystem.

The control parameters of the space area are interacted with the chart software through the saved file in GPX format, which is compatible with mainstream geographic information software and improves the data interaction efficiency. The beacon ball control module 120 is configured to determine whether the airborne beacon ball exceeds the safe area and whether to perform frequency switching, and send the self-destruction instruction and frequency switching instruction to the airborne beacon ball subsystem through the RS-232 protocol based on the ground data transmission radio module. The beacon ball control module 120 is configured to control the beacon machine module to switch different frequencies or remotely control the frequency change at a preset fixed interval in two ways: program control and remote control.

[0026] The key elements displayed by the comprehensive situation display module 100 mainly include: the position, heading, and speed of the ship, the position and flight trajectory of the beacon ball, etc. The embodiments of the present invention aim to realize the information interaction between the open-source chart and the beacon ball, the open-source chart and the ship, and the open-source chart and the ground parameter processing module to achieve this function. The specific implementation method is as follows: (1) Install the OpenCPN open-source chart application software on the computer platform and load the offline chart data; (2) Install the insertion positioning module and the corresponding antenna on the computer, and transmit the ship navigation information to the chart software in the NMEA0183 format through the simplex serial port. The ship navigation information includes time tags, position, speed, and heading, and the chart software overlays the layer to display the ship navigation information in real time; (4) Receive the beacon ball position information sent by the data preprocessing and area control setting module 110 and display it as a moving target in real time; (5) The chart software starts the disk storage function to record the position information and navigation paths of the ship and the beacon ball, and the disk storage format is the GPX format compatible with multiple types of software.

[0027] (6) The chart software reads the longitude and latitude of the path key points in the area control file and overlays and displays the safe area as a basis for manually judging whether the beacon ball is flying within the safe area, which is convenient for making a decision on whether to activate the forced self-destruction of the beacon ball.

[0028] The beacon machine module 140 of the embodiments of the present invention is configured to provide a downlink single-carrier beacon signal, and the downlink single-carrier beacon signal is used to verify the tracking phase of the device and record the optoelectronic deviation; the safety control module 160 is configured to receive the frequency switching instruction of the beacon ball data transmission radio station module 170 to control the frequency switching of the beacon machine module 140. The safety control module 160 is also configured to receive the safety control instruction of the beacon ball data transmission radio station module 170, the time setting of the beacon ball, the airspace setting information of the beacon ball, and control the self-destruction module 180 to start working.

[0029] The main functions of the data preprocessing and spatio-temporal domain setting module 110 include 4 parts, namely, processing the beacon ball position and sending it to the comprehensive situation display module 100, setting the communication parameters of the radio station and the chart software, time, and space area control parameters, and setting the safety control and frequency parameters.

[0030] The beacon ball control module 120 discriminates in real time whether the airborne beacon ball exceeds the safe area, whether it receives the safety control instruction from the post operator, and whether to perform frequency switching. It sends the self-destruction instruction and the frequency switching instruction to the ground data transmission radio module 130 through RS-232 and transmits them to the airborne beacon ball subsystem. The beacon ball control module 120 can adopt two methods: program control and remote control. The beacon signal frequency change can switch different frequencies at a preset fixed interval or be remotely controlled to change the frequency; Reference Figure 2 The main key points of the logical judgment process of the ground control subsystem shown are as follows: (1) Spatial area parameter setting The spatial area control parameters are divided into two categories: rectangular area and circular area. The rectangular authorized area is created by a rectangle formed by the northwest point and the southeast point set by the user, and the circular area is created by the center and radius set by the user.

[0031] (2) Time area parameter setting According to the user's requirements, a self-destruction time is set into the beacon ball. After the time countdown starts, if it is determined that the time is an unauthorized time (exceeding the preset cut-off time), a trigger signal is output to the safety control module to start the self-destruction module. The time setting accuracy is 1 minute.

[0032] (3)Send self-destruction instruction The data preprocessing and spatio-temporal domain setting module 110 sends a control command to the safety control module of the airborne beacon ball subsystem according to the ground needs to start the self-destruction module. This module receives the information returned by the airborne subsystem as it is and displays it on the ground subsystem software interface.

[0033] The ground data transmission radio module 130 provides a two-way transparent half-duplex serial communication wireless channel for the ground control subsystem and the airborne beacon ball subsystem, sends the safety control instruction, frequency switching instruction, time setting of the beacon ball, and airspace setting information of the beacon ball of the ground subsystem to the airborne beacon ball subsystem, and receives the beacon ball position information of the airborne beacon ball subsystem and sends it to the data preprocessing and spatio-temporal domain setting module through RS-232; The beacon machine module 140 provides a downlink single-carrier beacon signal for verifying the tracking phase of the equipment and recording the optoelectronic deviation; the positioning module 150 provides the beacon ball position information, adopts a general and standardized GPS / Beidou dual-mode positioning module, and the output format is NMEA0183, which is sent to the safety control module through the TTL serial port, and then sent to the beacon ball data transmission radio module 170 through RS-232 and downlinked to the ground control subsystem; The safety control module 160 receives and processes the frequency switching instructions of the beacon ball data radio module 170 to control the frequency switching of the beacon machine module, receives and processes the safety control instructions of the beacon ball data radio module 170, the time setting of the beacon ball, and the airspace setting information of the beacon ball, and controls the self-destruction module to start working; The beacon ball data radio module 170 provides a two-way transparent half-duplex serial port communication wireless channel for the airborne beacon ball subsystem and the ground control subsystem, receives the safety control instructions, frequency switching instructions, the time setting of the beacon ball, and the airspace setting information of the beacon ball from the ground control subsystem, sends them to the safety control module through RS-232, and receives the beacon ball position information of the safety control module and downloads it to the ground control subsystem; The ground control subsystem remotely controls the airborne beacon ball subsystem. After the command data is uploaded to the airborne beacon ball subsystem and the airborne beacon ball subsystem needs to complete specific actions, it controls frequency switching, completes time and space judgment, and self-destruction. The most important functions of the airborne beacon ball subsystem are frequency switching and self-destruction response; Reference Figure 3 The key points of the main function logic flow of the airborne beacon ball subsystem shown are as follows: The first step is to check the integrity of the received and demodulated data packet transmitted from the ground to determine whether the packet is valid; The second step is to set the area, time, and frequency parameters if it is valid; The third step is to determine whether the trigger condition is established; The fourth step is to make a response if it is established.

[0034] The self-destruction module 180 is the executor that completes the self-destruction of the beacon ball and makes it fall into the sea. The self-destruction device uses the thermal destruction method. The thermal destruction device is directly pasted on the ball skin with transparent tape, and the parallel thermistor thermal destruction method is reliable. Driven by an 8.4V DC voltage, the ball skin can be thermally destroyed within 2.5s, far exceeding the industry standard and reducing the secondary risk.
