Description

Technical Field

[0001] The present invention relates to the fields of Beidou communication and life-saving, and in particular to a position reporting method of a Beidou life-saving position reporting machine with low power consumption and high reliability. Background Art

[0002] The BeiDou-3 satellite message communication system consists of three parts: the user segment (user terminals), the space segment (BeiDou navigation satellites), and the ground segment (ground control center). The BeiDou-3 message communication system provides two-way message communication services to users. Message communication is divided into two processes: message sending and message receiving. User terminals send and receive messages via BeiDou satellite-to-ground and intersatellite links, as well as the ground master control station. After sending a message, users receive a confirmation message from the satellite. After receiving a message, users send a receipt message to the master control station.

[0003] Because the message communication service includes information reception, a user terminal, during normal communication, initiates a location update when its current location changes by more than a specified distance from the location last updated by the user. Upon receiving the location update from the user, the access satellite forwards it to the master control station, which then updates the user's location information to ensure it can select the appropriate satellite to broadcast message information to the user.

[0004] The Beidou emergency position reporting device is primarily used to locate and report the position of personnel in distress during missions. It must be carried with the person and is not powered on during normal missions. It is designed to operate in harsh environments, including those in the air, on land, and on water. The Beidou RDSS transmitter consumes 5V*2.5A=12.5W, the Beidou RDSS receiver consumes 3.3V*1.5A=4.95W, and the main control board's operating power consumption is 3.3V×0.04A=0.132W.

[0005] The conventional reporting method of the existing life-saving position reporting machine is that when people are in distress, the life-saving equipment is in the normal power-on state. After pressing the distress button, the one-button call process is completed, and short messages such as location information and other related distress signals are continuously sent to the ground control center. If the call for help is to be canceled, the cancel button is pressed to restore to the original working state.

[0006] This method of reporting a person's location consumes a lot of power, uses a single, inflexible short message communication method, and has a limited battery lifespan. Furthermore, in real-world situations, the distressed person's situation is complex and unpredictable, and the lifesaver's location is in an uncontrollable environment. When the signal is unstable or interfered with, the lifesaver's locations may not always be able to successfully send short messages to the ground control center. This significantly increases the risk to the person's life and hinders the acquisition of critical geographic coordinates during the search and rescue operation, leading to serious rescue failures.

[0007] The existing life-saving position reporting process consumes a lot of power and the short message communication method is single and cannot be adapted. Not only can timely position reporting not be realized efficiently, but due to the high power consumption, the life-saving equipment cannot maintain short message sending for a long time, and the position reporting process is not reliable enough, which greatly increases the difficulty of search and rescue. Summary of the Invention

[0008] In view of the problems existing in the prior art, the purpose of the present invention is to provide a low-power and high-reliability Beidou life-saving position reporting method.

[0009] In order to achieve the above objectives, the present invention adopts the following technical solutions to achieve them.

[0010] A method for reporting a position of a Beidou life-saving position reporting device with low power consumption and high reliability, comprising the following steps:

[0011] Step 1: The Beidou life-saving position reporting machine sends a distress short message through the RDSS module according to the default reporting mode; the Beidou life-saving position reporting machine is always in the state of receiving manual commands, and the Beidou life-saving position reporting machine is in the state of receiving distress confirmation signals when the RDSS module is turned on;

[0012] Step 2: The Beidou life-saving position reporting device operates according to the manual command or the reception of the distress confirmation signal;

[0013] If the Beidou life-saving position reporting machine does not receive a manual command or a distress confirmation signal, it will send a distress short message through the RDSS module according to the default reporting mode until the Beidou life-saving position reporting machine runs out of power;

[0014] If the Beidou life-saving position reporting machine receives a manual instruction, it will work in the specified working mode according to the manual instruction received;

[0015] If the Beidou life-saving position reporting machine receives a distress confirmation signal, the RDSS module of the Beidou life-saving position reporting machine will continue to be turned on, and the Beidou life-saving position reporting machine will enter the state of receiving remote control commands; if the Beidou life-saving position reporting machine does not receive a remote control command within 30 minutes of entering the state of receiving remote control commands, step 1 will be repeated; if the Beidou life-saving position reporting machine receives a remote control command within 30 minutes of entering the state of receiving remote control commands, a remote control command confirmation signal will be sent, and the machine will work according to the remote control command until the power is exhausted or the remote control command is completed. After the remote control command is completed, step 1 will be repeated.

[0016] Compared with the existing technology, the beneficial effects of the present invention are: multiple reporting modes can be flexibly switched on demand, which can significantly save the power of the Beidou life-saving reporting machine, greatly improve the working time of the life-saving equipment, and ensure that the life-saving equipment can more efficiently and reliably realize the notification of life-saving information even in the case of unstable signals, providing practical guarantee for the success of the rescue mission. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Figure 1 The present invention is a flowchart of a method for reporting a position of a Beidou life-saving position reporting device with low power consumption and high reliability. DETAILED DESCRIPTION

[0019] The embodiments of the present invention will be described in detail below with reference to examples. However, those skilled in the art will understand that the following examples are only used to illustrate the present invention and should not be construed as limiting the scope of the present invention.

[0020] refer to Figure 1 A method for reporting a position of a Beidou life-saving position reporting device with low power consumption and high reliability comprises the following steps:

[0021] Step 1: The Beidou life-saving position reporting machine sends a distress short message through the RDSS module according to the default reporting mode; the Beidou life-saving position reporting machine is always in the state of receiving manual commands, and the Beidou life-saving position reporting machine is in the state of receiving distress confirmation signals when the RDSS module is turned on;

[0022] Specifically, the default reporting mode includes the first and second stages:

[0023] Phase 1: The BeiDou life-saving position reporting device turns on the RDSS module and RNSS module for RDSS positioning and RNSS positioning respectively, and keeps the RDSS module and RNSS module turned on. Starting from the first RDSS positioning result, a short distress message is sent every 60 seconds for 30 times. After the 30th distress message is sent, the device enters the second phase.

[0024] Phase 2: Starting from the start of the second phase, a distress message is sent every 30 minutes. The RNSS module of the Beidou life-saving position reporting device is turned on 3 minutes before the distress message is sent to perform RNSS positioning, and is turned off 3 minutes after the distress message is sent. The RDSS module is turned on 10 seconds before the distress message is sent and is turned off 2 minutes after the distress message is sent.

[0025] Before obtaining an RNSS positioning result, the longitude and latitude in the distress message sent by the RDSS module are based on the longitude and latitude of the first RDSS positioning result. After obtaining an RNSS positioning result, the longitude and latitude in the distress message sent by the RDSS module are based on the longitude and latitude of the RNSS positioning result. Because the cold start of the RNSS module is slower than that of the RDSS module, the RDSS module will perform RDSS positioning first, and then perform RNSS positioning after the RNSS module is started.

[0026] Step 2: The Beidou life-saving position reporting device operates according to the manual command or the reception of the distress confirmation signal;

[0027] If the Beidou life-saving position reporting machine does not receive a manual command or a distress confirmation signal, it will send a distress short message through the RDSS module according to the default reporting mode until the Beidou life-saving position reporting machine runs out of power;

[0028] If the Beidou life-saving position reporting machine receives a manual instruction, it will work in the specified working mode according to the manual instruction received;

[0029] Specifically, the working modes include high-speed working mode, low-speed working mode and default position reporting mode;

[0030] If the Beidou life-saving position reporting machine receives a high-speed working mode instruction, the Beidou life-saving position reporting machine will send a short distress message in the high-speed working mode; if the Beidou life-saving position reporting machine receives a low-speed working mode instruction, the Beidou life-saving position reporting machine will send a short distress message in the low-speed working mode; if the Beidou life-saving position reporting machine receives a default reporting mode instruction, the Beidou life-saving position reporting machine will send a short distress message in the default reporting mode;

[0031] High-speed working mode: the RDSS module and RNSS module remain on, transmitting a short message every 1 minute until the battery is exhausted or a distress confirmation signal is received;

[0032] The low-speed working mode is: a short message is transmitted every 1 hour until the battery is exhausted or a distress confirmation signal is received; among them, the RNSS module of the Beidou life-saving positioning machine is turned on 5 minutes before the distress short message is sent to perform RNSS positioning, and is turned off 5 minutes after the distress short message is sent; the RDSS module is turned on 5 minutes before the distress short message is sent, and is turned off 5 minutes after the distress short message is sent.

[0033] If the Beidou life-saving position reporting machine receives a distress confirmation signal, the RDSS module of the Beidou life-saving position reporting machine will continue to be turned on, and the Beidou life-saving position reporting machine will enter the state of receiving remote control commands; if the Beidou life-saving position reporting machine does not receive a remote control command within 30 minutes of entering the state of receiving remote control commands, step 1 will be repeated; if the Beidou life-saving position reporting machine receives a remote control command within 30 minutes of entering the state of receiving remote control commands, a remote control command confirmation signal will be sent, and the machine will work according to the remote control command until the power is exhausted or the remote control command is completed. After the remote control command is completed, step 1 will be repeated.

[0034] Although this specification has provided a detailed description of the present invention using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made based on the present invention. Therefore, such modifications and improvements, which do not depart from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
