FIG1 is a schematic structural diagram of a police drone training system provided by an embodiment of the present invention. As shown in FIG1 , the police drone training system may include: a ground station cabinet 11 , a drone 12 and a mobile terminal 13 .

The ground station cabinet 11 is connected to the ground station computer 111 and the drone 12 respectively.

The ground station computer 111 is used to generate training information, which includes flight missions. The training information is used to prompt trainees to operate the drone 12 to perform flight missions.

The ground station computer 111 is equipped with the police training and testing drone ground software, which is developed using C++ language and Qt interface framework. The ground station computer 111 can communicate with the drone 12 through the ground station cabinet 11, and the communication protocol uses an internally defined private protocol.

The police training and testing drone ground software has multiple role login functions, including site administrator, examiner, examinee, coach and trainee, which can be switched according to needs. For example, when the site administrator logs in, he has the authority to change the relevant parameters of the training site; when the coach logs in, he can select the training subject.

The ground software of the police training and examination drone has a site mode conversion function, which can switch between training mode and examination mode to meet the different functional requirements of the same site in training and examination modes. This function is authorized to the site administrator.

The ground software of the police training drone has a personnel information management function, which can add and delete personnel, including but not limited to coaches and trainees. The training information includes the operator, that is, the trainee, so that the trainee can be clearly instructed to operate the drone 12 to perform the flight mission. The training information also includes the trainee's corresponding trainer, which helps the trainer to follow up the trainee's training in a timely manner. The personnel information management function is authorized to the venue manager.

The ground software of the police training drone has the function of automatically demonstrating standard flight missions. When the automatic demonstration function is activated, the ground station computer 111 communicates with the drone 12 through the ground station cabinet 11 to control the drone 12 to perform operation demonstrations. The demonstration process can be paused or continued at any time. At the same time, the progress bar can be dragged to adjust the current demonstration progress. During the demonstration progress adjustment, the drone 12 remains in a hovering state. When the adjustment progress is determined, the drone 12 flies from the current position to the position after the progress adjustment, and continues the subsequent flight demonstration according to the standard flight mission.

The ground software of the police training drone has the functions of starting, pausing and terminating the training subject sequence. The operator can start or stop the authorization of a certain flight subject training through the ground software of the police training drone, but the actual normal start or end of the subject is subject to the take-off or landing of the drone.

The ground software of the police training drone has the function of playing teaching videos. The software has built-in video resources and players, and can project teaching videos to other playback devices for teaching.

The ground software of the police training and testing drone has a recording function. The ground software of the police training and testing drone can record information such as the current operator ID, time, training venue number, etc.

The drone 12 is used to perform flight missions and send flight data obtained during the flight missions to the ground station cabinet 11. The drone 12 is equipped with a data transmission module, a positioning module, an inertial measurement module, a magnetic measurement module, a pressure measurement module, and a height measurement module, which can obtain various flight data of the drone 12 in the process of performing the flight mission in real time. In particular, the positioning module and the height measurement module can obtain the longitude, latitude and altitude of the location of the drone 12 in the process of performing the flight mission. These flight data are used to draw the flight trajectory of the drone 12.

The ground station cabinet 11 is used to receive flight data and send the flight data to the ground station computer 111 .

The ground station cabinet 11 also includes a switch, a ground station information management module and a power management module. The switch is used to communicate with external devices, the ground station information management module is used to store data, and the power management module is used to power the ground station cabinet 11 and some external devices.

The ground station cabinet 11 has a 6U cabinet appearance and provides 10 network interfaces for connecting various network devices. The ground station cabinet 11 includes 1 AC input, 1 device 24V output, and 2 HDMI outputs. The 24V output circuit is used to power other training equipment. The 2 HDMI outputs are used to display the police training drone software and ground PC system administrator software on the ground station computer 111.

The ground station computer 111 is used to receive flight data, determine the flight trajectory according to the flight data, and use training rules to compare the flight trajectory with the reference trajectory to generate a training report. The training report is used to prompt the trainee on the accuracy of performing the flight mission. The reference trajectory includes the longitude, latitude and altitude of the marked flight trajectory. The longitude, latitude and altitude can be divided into several error intervals, each error interval corresponds to a certain deduction value. When the flight trajectory is compared with the reference trajectory, the score of the flight mission is determined by the error value between the reference trajectory. At the same time, the point of losing points can also be determined, and then a training report is formed. The flight trajectory is generated in real time according to the execution of the flight mission by the drone 12, so the score also changes in real time. It can be set that when the score is lower than the set value, the ground station computer 111 sends a return command to the drone 12 through the ground station cabinet 11 to stop training. This shows that the trainee has major defects in the operation of the drone 12 and needs further learning, which improves the training efficiency.

When an abnormality occurs in the UAV 12 and the training is interrupted, the ground station computer 111 will automatically store the flight data, and after the fault is eliminated, the user can choose to continue the training or retrain.

The mobile terminal 13 is used to generate a simulated flight animation according to the flight data. The simulated flight animation is used for trainees to watch the process of operating the UAV to perform a flight mission.

As a possible implementation, in combination with FIG1 , as shown in FIG2 , the training system for a police drone further includes at least one position marker 14, each of which is connected to a ground station cabinet 11. Each position marker 14 is used to collect position data of a preset position and send the position data to the ground station cabinet 11.

As shown in FIG. 14 , since different training venues are located at different locations, a location marker 14 is required to collect the longitude and latitude of the location of the training venue, and the location marker 14 includes at least one.

Each position marker 14 is numbered. For example, when the position marker 14 includes a first position marker, a second position marker, a third position marker, a fourth position marker, a fifth position marker, a sixth position marker, a seventh position marker and an eighth position marker, the above position markers are placed as shown in FIG14, and the placement position is the preset position. The position marker 14 is equipped with a positioning module and a data transmission module. The positioning module can collect the longitude and latitude of the position marker 14. The longitude and latitude data are the position data, which are then sent to the ground station cabinet 11 through the data transmission module.

The ground station cabinet 11 is also used to receive at least one position data and send it to the ground station computer 111. The ground station computer 111 is also used to generate a reference trajectory based on at least one position data. Exemplarily, when the flight mission is an "8-shaped route", the flight route of the drone 12 can be described as the first position marker-the fifth position marker-the fourth position marker-the third position marker-the first position marker-the eighth position marker-the seventh position marker-the sixth position marker-the first position marker. The ground station computer 111 generates a reference trajectory based on the position data collected by each position marker 14 and the flight altitude requirement.

At the same time, the position marker 14 can also be used to identify trainees when they are performing flight missions, prompting the trainees to operate the drone 12 according to the flight missions.

At least one position marker 14 includes a take-off and landing position marker 141. The take-off and landing position marker 141 is also used to obtain the take-off signal and the landing signal of the UAV 12, and send the take-off signal and the landing signal to the ground station cabinet 11. The take-off signal is used to indicate whether the UAV 12 has taken off, and the landing signal is used to indicate whether the UAV 12 has landed. The ground station cabinet 11 is also used to receive the take-off signal and the landing signal and send them to the ground station computer 111;

The ground station computer 111 is also used to determine the duration of the UAV 12 performing the flight mission according to the take-off signal and the landing signal.

Continuing to refer to FIG. 14 , exemplarily, the landing position marker 141 has an “H” mark, and the size of the landing position marker 141 is larger than that of other position markers 14. The landing position marker 141 also includes a pressure sensing module. The UAV 12 first docks on the landing position marker 141. When the UAV 12 takes off, the landing position marker 141 senses the pressure change and sends a take-off signal to the ground station cabinet 11. The ground station cabinet 11 sends the take-off signal to the ground station computer 111. The ground station computer 111 starts timing after receiving the take-off signal. When the UAV 12 completes the flight mission, it lands on the landing position marker 141. The landing position marker 141 senses the pressure change and sends a landing signal to the ground station cabinet 11. The ground station cabinet 11 sends the landing signal to the ground station computer 111. The ground station computer 111 ends timing after receiving the landing signal. According to the take-off signal and the landing signal, the duration of the UAV 12 performing the flight mission can be determined.

As a possible implementation, in combination with FIG1 , as shown in FIG2 , the training system of the police drone 12 further includes a weather station 15 , and the weather station 15 is connected to the ground station cabinet 11 ;

The weather station 15 is used to collect weather data in real time during the UAV 12 performing a flight mission, and send the weather data to the ground station cabinet 11. The weather data includes wind direction and wind force. The UAV 12 is greatly affected by the weather, especially the wind force, during the mission. The weather station 15 can collect weather data in real time, including wind direction and wind force, and send it to the ground station cabinet 11.

The ground station cabinet 11 is also used to receive meteorological data and send it to the ground station computer 111. The training information includes meteorological data. The ground station cabinet 11 sends the received meteorological data to the ground station computer 111, and the ground station computer 111 records and displays it.

As a possible implementation, in combination with FIG. 1 , as shown in FIG. 2 , the training system of the police drone 12 further includes a prompt terminal 16 , and the prompt terminal 16 is connected to the ground station cabinet 11 .

The ground station computer 111 is also used to send training information to the ground station cabinet 11

The ground station cabinet 11 is also used to receive training information and send the training information to the prompt terminal 16.

The prompt terminal 16 is used to receive the training information, and play and display the training information.

Since the training site is large, there is a certain distance between the ground station computer 111 and the trainee operation area. The prompt terminal 16 is generally set in the trainee operation area to facilitate the trainee to understand the training information, environmental parameters, etc. The prompt terminal 16 includes a display screen and an audio system, which can receive the training information, play the training information through the audio system and display the training information through the display screen. The training information includes but is not limited to time, weather data, operator, current subject, and remaining time.

As a possible implementation, in combination with FIG. 1 , as shown in FIG. 3 , the training system of the police drone 12 also includes a server 17 , the server 17 is connected to the ground station cabinet 11 , and the mobile terminal 13 is connected to the server 17 .

The server 17 is used to receive and store flight data and training reports.

The mobile terminal 13 is used to request flight data and training reports from the server 17 .

The server 17 is equipped with a database and a police training and testing drone software server software. The database uses mysql. The police training and testing drone software server software uses springboot and springcloud distributed microservice architecture. After receiving the training report, the server 17 stores the training report in the database.

The server 17 can provide a data storage interface: use a specified protocol format to store data or data sets of different services, and return a specified code value indicating success upon success. Return the reason for failure upon failure. For example, the ground station software of the examination room uploads the flight data of the examinee to the server.

The server 17 provides a data acquisition interface: uses a specified protocol format and keyword parameters to search for data or data sets of different services, and sends the search results to the mobile terminal.

The server 17 provides a client login interface: use the specified protocol format and user name and password to log in, and return role attribute parameters after successful login, including the role type, which is used to enable client functions; if the login fails, the failure reason is returned.

The server 17 provides a role information management interface: the authority of each role is uniformly formulated using a specified protocol format, and the information of the specified role is edited. For example, a student changes the contact information and uses a mobile terminal to modify it, or a venue manager deletes the information of a student.

The server 17 provides a role relationship management interface: using a specified protocol format to modify the relationship between two roles, such as specifying that the coach of student A is coach B.

The server 17 provides a site verification interface: the ground station computer 111 uploads the location data collected by the location marker 14 to the server 17 through the ground station cabinet 11, and the server 17 compares the location data with the standard site data in the database. If the verification is successful, success is returned, and if the verification fails, the reason for the failure is returned. Exemplarily, if the distance between the first location marker and the second location marker is too short, the verification fails. Training is not allowed after verification fails, and the location marker 14 needs to be adjusted and verified before training can be carried out, so that the accuracy of the training can be guaranteed.

The server 17 provides a subject parameter verification interface: the ground station computer 111 uploads the relevant parameters of the training subject to the server 17 through the ground station cabinet 11. The server 17 verifies the relevant parameters. Exemplarily, the ground station computer 111 uploads the meteorological data collected by the meteorological station 15 to the server 17 through the ground station cabinet 11. When the wind force in the meteorological data is too strong, the verification fails and the reason for the failure is returned. This can prevent unreasonable factors from affecting the effect of training.

The server 17 provides a chat content management interface: the mobile terminal 13 communicates with the server 17, and the server 17 verifies and stores the legality of the chat content, blocks illegal words, and maintains the communication environment.

The mobile terminal 13 can be a mobile phone or a notebook. The mobile terminal 13 is equipped with a police training drone software mobile app. The police training drone software mobile app uses the retrofit2 http request framework and uses the rest api to request data. The local storage uses the sqlite3 database, and the ORM uses greenDAO. After the http request, the recyclerview control is used for layout and display on the page of the mobile phone or notebook. The data interaction with the server 17 is carried out through the 4G/5G network, and the communication protocol uses an internally defined private protocol.

The server 17 is used to receive and store the training rules, and send the training rules to the ground station computer 111 via the ground station cabinet 11.

The server 17 is also used to verify the training report according to the training rules and generate a verification result, which is used to indicate whether the training report is abnormal. The server 17 provides a score verification and storage interface: after the ground station computer 111 generates the training report, the training report will be sent to the server 17 through the ground station cabinet 11. The server 17 verifies the training report and determines whether the training report is abnormal. If the verification is successful, the training report is stored in the database and can be requested by the mobile terminal 13. If the verification fails, the failure reason is returned, the training report is judged to be invalid, and the failure reason is sent to the mobile terminal 13.

As a possible implementation, the ground station computer 111 is also used to send a return instruction to the ground station cabinet 11 when it is determined according to the flight data that the drone 12 flies out of the preset range. The ground station cabinet 11 is also used to receive the return instruction and send the return instruction to the drone 12.

Since trainees have different abilities in operating drones to perform flight missions, in order to prevent the drones from flying out of the training ground and causing danger, as shown in FIG. 14 , position markers 14 are set around the training ground. The position marker 14 collects the position data of the preset position, which specifically refers to the longitude and latitude of the edge of the training ground, and sends the position data to the ground station cabinet 11. When the ground computer 12 determines that the drone flies out of the preset range based on the flight data, which specifically refers to the training ground, the ground computer 12 sends a return command to the ground station cabinet 11, and the ground station cabinet 11 sends the return command to the drone 12. When the drone 12 receives the return command, it will no longer accept the control of the trainees and will return directly to land on the take-off and landing position marker 141. Prevent the drone 12 from flying out of the training ground and causing danger.
