[0051] In the description and claims of the present invention and the above - mentioned drawings, terms such as "first", "second", "third", "fourth", etc. (if any) are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments described herein can be implemented in an order different from that illustrated or described herein. In addition, the terms "comprising" or "having" and any variations thereof are intended to cover non - exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily limit to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0052] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to Figure 1 In the first aspect of the present invention, a method for position status interaction between walkie - talkies is provided, including:

[0053] S100. In response to a request for updating the position information of the networking device, obtain the first position status information of the local walkie - talkie; in the present invention, the walkie - talkie device used integrates an APRS (Automatic Position / Packet Report System) automatic position reporting system. Refer to Figure 2 In terms of hardware composition, the walkie - talkie device used in the present invention includes a central processing unit, a cache unit, a transmitting unit, and a receiving unit. Among them, the transmitting unit specifically includes a positioning unit, a compass unit, a digital signal generating unit, and a radio frequency transmitting unit, and the receiving unit further includes a radio frequency receiving unit, a permanent storage unit, a digital signal solving unit, and a display processing unit.

[0054] In an alternative implementation manner of step S100 of the present invention, the obtaining the first position status information of the local walkie - talkie in response to the request for updating the position information of the networking device includes: generating the position information update request at preset intervals (for example, 1 - 5 minutes) or when receiving a refresh instruction from the user (for example, the user clicks the refresh button on the first interface); and obtaining the first position status information of the local walkie - talkie in response to the request for updating the position information of the networking device.

[0055] S200. Modulate the first position status information and send it to surrounding networked walkie-talkies via radio frequency. In an alternative implementation of step S200 of the present invention, the operation of modulating the first position status information and sending it to surrounding networked walkie-talkies via radio frequency includes: packetizing the first position status information through the AX.25 protocol, and obtaining a first sine wave signal by using AFSK modulation; then modulating the first sine wave signal through FM modulation and sending it to surrounding networked walkie-talkies through the radio frequency antenna of the local walkie-talkie.

[0056] Specifically, in the present invention, the local walkie-talkie first obtains the first position status information of the local unit (including but not limited to GPS coordinate information, status information, and call sign information). It will first be packetized through the AX.25 protocol and use the AFSK modulation method. In AFSK, a 1200HZ sine wave represents the number 1, and a 2200HZ sine wave represents the number 0. Then, the generated sine wave signals are modulated to the radio frequency end and transmitted. The call sign is unique, ensuring the distinction between different devices. After receiving the information, the surrounding walkie-talkies first demodulate the baseband signal of AFSK through FM, and then send it to the digital signal processing unit for decoding to analyze the digital 0 and 1 data represented by the 1200HZ and 2200HZ sine waves. The protocol analysis unit analyzes the AX.25 data packet and obtains the GPS coordinate information, status information, and call sign information of the other party after CRC check.

[0057] The full name of CRC check is Cyclic Redundancy Check. It is an important class of linear block codes with simple encoding and decoding methods, strong error detection and correction capabilities, and is widely used in the communication field to implement error control. In the present invention, the CRC check uses 16-bit CRC-CITT, and the calculation formula is x16 + x12 + x2 + 1. Let the original information polynomial before encoding be P(x), and the highest power of P(x) plus 1 is equal to k; the generating polynomial is G(x), and the highest power of G(x) is equal to r; the CRC polynomial is R(x); the information polynomial with CRC after encoding is T(x). Encoding method of the sender: Multiply P(x) by x r (that is, the corresponding binary code sequence is shifted left by r bits), and then divide it by G(x). The obtained remainder is R(x). It is expressed by the formula T(x) = x r P(x) + R(x). Decoding method of the receiver: Divide T(x) by G(x). If the remainder is 0, it means that there is no error in the transmission. Otherwise, it means that the transmission is incorrect.

[0058] S300. Receive a radio frequency signal containing second position status information fed back by the surrounding networked walkie-talkie based on the automatic position reporting system. It should be noted that the information sending and information demodulation used by any walkie-talkie device in the network of the present invention adopt the same protocol method. Therefore, in an optional implementation manner of S300 of the present invention, the receiving of the radio frequency signal containing second position status information fed back by the surrounding networked walkie-talkie based on the automatic position reporting system includes: receiving the radio frequency signal containing second position status information fed back by the surrounding networked walkie-talkie based on the automatic position reporting system; performing FM demodulation on the radio frequency signal to obtain a second sine wave signal; performing AFSK demodulation on the second sine wave signal to obtain an AX.25 data packet; and after performing CRC check on the AX.25 data packet, obtaining the second position status information.

[0059] S400. Generate a device list and a relative position map of the local walkie-talkie and the surrounding walkie-talkies in the first interface of the local walkie-talkie based on the first position status information and the second position status information. Figure 3 Illustrates the display manner of the device list and the relative position map on the first interface of the walkie-talkie of the present invention.

[0060] In an optional implementation manner of step S400 of the present invention, the generating of the device list and the relative position map of the local walkie-talkie and the surrounding walkie-talkies in the first interface of the local walkie-talkie based on the first position status information and the second position status information includes:

[0061] Extract device call sign information from the first position status information and the second position status information; generate the device list based on the device call sign information; extract device position information from the first position status information and the second position status information; and generate the relative position map based on the device position information.

[0062] Furthermore, the step of generating the device list further includes writing relevant attribute parameters (including distance, azimuth, and speed). That is, based on the device position information of the local walkie-talkie and the surrounding walkie-talkies, calculate the distance information and the azimuth information between the surrounding walkie-talkie and the local walkie-talkie; and write the distance information and the azimuth information into the relevant attribute parameters of the surrounding walkie-talkie in the device list. The local walkie-talkie of the present invention automatically calculates the distance information between the local and other teammates every certain period of time (1 minute). Devices that can receive position replies within 10 minutes are marked as online status, and devices that have not received for more than 10 minutes are marked as timed-out offline status.

[0063] In the present invention, after obtaining the position status information of the other party, the relative distance and relative direction are calculated through an algorithm in combination with the position information of the local device. Since the Earth is elliptical, the calculation of distance is relatively complex. To adapt to the use on walkie-talkies, a simplified algorithm, namely the Haversine formula method, is adopted for calculation. It is a mathematical formula for calculating the distance between two coordinate points on a sphere and is particularly suitable for calculating the spherical distance on the Earth. This formula is based on spherical trigonometry and uses the arc length between two points on the sphere to calculate the distance between them. The form of this formula is as follows:

[0064]

[0065] distance=R·c

[0066] Where:

[0067] ·lat 1 ,lon 1 are the latitude and longitude of the first point;

[0068] ·lat 2 ,lon 2 are the latitude and longitude of the second point;

[0069] ·Δlat is the difference in latitude (lat 2 -lat 1 );

[0070] ·Δlon is the difference in longitude (lon 2 -lon 1 );

[0071] ·R is the radius of the Earth (usually taken as 6371 km);

[0072] ·atan2 is the arctangent function.

[0073] The azimuth angle (i.e., the relative direction) is the horizontal angle between the north-pointing meridian of a certain point and the target direction line in the clockwise direction (as shown by θ in Figure 4 ), which can be regarded as the angle indicated by a compass, that is, the magnitude of the dihedral angle formed by the OPN plane and the OPQ plane. The specific calculation formula can be as follows: Where λ1, are the longitude and latitude of the first point, and λ2, are the longitude and latitude of the second point. Substituting them into the above formula can calculate the azimuth angle.

[0074] In an alternative embodiment of the first aspect of the present invention, after generating the device list and the relative position map of the local intercom and the surrounding intercoms in the first interface of the local intercom based on the first position status information and the second position status information, the following steps are included:

[0075] Receive a click by the user on a specified intercom in the device list to generate a function menu for the specified intercom (see Figure 5 ), the function menu includes position tracking, path playback, and path following; receive the user's selection of the function menu, enter the information interface of the function menu, and generate the detailed data information of the specified intercom and the function sub-map of the function menu. Figure 6 、 Figure 7 and Figure 8 respectively show the first information interface when the function menu is position tracking, the second information interface when it is path playback, and the third information interface when it is path following. In the present invention, position tracking, path playback, and path following. Position tracking and path following are different. Position tracking puts the latest position of the other party into the calculation formula, and path following is to completely follow the path walked by the other party, and sequentially put the positions of the other party from the oldest to the latest into the calculation formula.

[0076] More specifically, in the present invention, after selecting position tracking, the detailed information of the teammate can be viewed. Figure 6 The middle arrow is the current direction, and the dot is the azimuth of the target. The distance, azimuth, status, and the distance and movement yaw direction required to navigate to this point can be prompted through the navigation interface. Therefore, even when the other party's information cannot be received again during rescue, the position of the rescued person can be tracked through the last saved waypoint.

[0077] Selecting path playback can view the recently walked path of the teammate, providing a more valuable information reference for rescue and outdoor activities. Each time the receiver receives the APRS information of the teammate, their position information will be saved in the storage medium unit, storing one point every 1 minute or every 10 meters, and 10,000 points can be stored, facilitating position following. As Figure 7 shown, it can be seen that the dot is the position of the other party, the dotted line is the path walked by the other party, and the speed, longitude, and latitude at that time are shown on the left.

[0078] Selecting path following is to walk along the path walked by the teammate again. Especially for the people at the end of the team, they can walk along the path walked by the people in front. When the front team changes the route of travel and does not notify the rear team in time, this function can effectively solve this situation. As Figure 8As shown, it can be seen that the arrow indicates the position of the current person, the dashed line is the path taken by the teammate, and the dot is the final position of the teammate. The distance to the other party and the yaw angle calculated based on the path can be displayed on the left. Each time APRS information is received, it includes the longitude and latitude information of the other party and the direction of the compass. Then, this information is stored in each waypoint information. Suppose 4 waypoints are stored, and their directions are 92°, 30°, 15°, and 45° respectively. If the compass direction of the local machine at the position of waypoint 1 is 10°, then it needs to turn right by 82° and then move forward. In this way, the direction can be corrected in time when passing through each stored waypoint.

[0079] Generally speaking, the technical solution of the present invention is that communication between walkie-talkies does not need to pass through other servers, and the azimuth map can be directly displayed on the walkie-talkie. In the actual use process, it can be set to send the digital information of APRS by releasing the PTT, or it can be set to automatically send APRS information at intervals. The intervals can be 30 seconds, 1 minute, 5 minutes, or 10 minutes. When the user releases the PTT or the automatic transmission cycle arrives, the central processing unit first obtains the longitude and latitude, ground speed, ground course, and compass direction information from the positioning unit and the compass unit respectively, and packs and sends them to the digital signal generating unit. At this time, the conversion from digital information to analog baseband is completed. When passing through the digital signal generating unit, the AFSK modulation method is used, and the sine wave of 1200HZ represents 1, and the sine wave of 2200HZ represents 0, and then an analog baseband signal is generated.

[0080] These baseband signals pass through the radio frequency transmitting unit, are frequency-converted by FM modulation and transmitted through the antenna. After the radio frequency receiving unit receives the signal, the digital signal calculation unit calculates the digital 0 and 1. After the central processing unit verifies and confirms that it is an APRS data packet, it parses and extracts information such as longitude and latitude, ground speed, ground course, time, and compass direction, and displays this information on the display processing unit. The distance and azimuth angle between the other party and the local machine can be calculated through the positioning unit of the local machine. In this way, each walkie-talkie user supporting APRS can see the distance and direction between nearby users.

[0081] In addition, the parsed information will be saved as a waypoint in the cache unit. The central processing unit reads the information in the cache unit and allocates a storage space in the permanent storage unit for the same call sign. The waypoints of the same call sign should be stored in the same area and stored in a FIFO manner, which ensures continuous storage and avoids the problem of insufficient space for storage.

[0082] Different call signs are in different address spaces, which ensures that the waypoint information between call signs is not interfered with or overwritten. During path tracking, the central processing unit obtains the longitude, latitude, speed, heading, and compass direction information of the latest waypoint of the selected call sign from the permanent storage unit, and calculates the distance based on the longitude and latitude information obtained by the positioning unit. In addition, the compass direction is read from the oldest waypoint information of the call sign and compared with the compass unit to calculate the yaw angle.

[0083] In the technical solution of the present invention, the walkie-talkie directly and real-time shares the position through the APRS function and displays the azimuth, speed, and heading. In addition, the last received target position can provide a position reference for rescue, the position can be replayed to view the path of teammates, and the path tracking is convenient for the subsequent team to move forward. Through this solution, the position information can be shared with teammates, simplifying the voice communication and confirmation. During the rescue process, the position of the other party can be accurately obtained, reducing the difficulty of rescue. It is convenient for the team to move forward during outdoor activities and avoid falling behind.
