Description

Technical Field

[0002] The Beidou Satellite Short Message System is an important part of the Beidou Navigation Satellite System independently developed by China. The system provides users with a unique two-way short text communication service. The Beidou satellite system has global coverage capabilities, ensuring that stable satellite signals can be obtained in the coverage area. It allows users to not only receive information, but also send short text messages, realizing two-way communication between users and users, and between users and the central control system. Combined with the positioning function of the Beidou satellite navigation system, the short message system can achieve accurate position reporting and tracking.

[0003] After a disaster, ground communication facilities are often easily damaged, resulting in communication interruption, while the Beidou satellite short message system is not affected by ground infrastructure and can maintain communication capabilities in areas with no or weak signals, ensuring the timely delivery of rescue information. The Beidou short message system, combined with the positioning function of the Beidou satellite navigation system, can achieve accurate location reporting and tracking, helping rescue personnel to quickly and accurately find the location of the incident, improving rescue efficiency, and providing stable and reliable communication guarantees and accurate and efficient positioning services for rescue operations. It is a powerful tool for responding to disasters and emergencies.

[0004] However, professional Beidou communication tools have high manufacturing and use costs. If each rescuer is equipped with a Beidou short message transceiver in a large-scale emergency rescue operation, it will not only incur huge expenses, but also the rescuers may not know how to use it. In addition, in certain specific areas or environmental conditions, such as mountainous areas and basements, the reception of Beidou satellite signals may be interfered or restricted, which further increases the complexity and difficulty of the rescue operation and reduces the effectiveness and efficiency of the rescue operation.

[0050] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] In order to solve the problems existing in the Beidou system in emergency rescue, the first embodiment of the present invention provides an emergency rescue communication gateway based on Beidou short messages as a supplement to Beidou terminal communication. Figure 1 As shown, the gateway includes a main control module, a Beidou short message communication module, a radio frequency communication module, a 4G communication module, a network port module and a power module; the main control module is connected to the Beidou short message communication module, the radio frequency communication module, the 4G communication module, the network port module and the power module.

[0052] The emergency rescue communication gateway in the embodiment of the present invention is a key component connecting the on-site terminal equipment and the remote command center, plays a key role in connection and data transmission, and is an important hub to ensure that on-site information can be transmitted to the command center in a timely and accurate manner.

[0053] In an embodiment of the present invention, a radio frequency communication module is used to establish a radio frequency communication link with a user terminal to transmit a communication request. The radio frequency communication module can create a radio frequency network coverage that is independent of relay nodes, and can establish a radio frequency communication relationship with user terminals within the coverage range. Preferably, the communication frequency band selects the 433MHz frequency band, which has strong signal penetration and anti-interference capabilities, and low transceiver power consumption, and is suitable for use in radio frequency communications for emergency rescue. In some other embodiments, Zigbee and other methods can also be used to achieve communication between the gateway and the user terminal. The radio frequency communication coverage constructed by the embodiment of the present invention can cover a range of more than 2 kilometers. Compared with each rescuer being equipped with a Beidou transceiver terminal, it saves a lot of equipment and terminal purchase costs, and also saves the management and maintenance costs of the terminals.

[0054] The main control module is used to parse the communication request transmitted by the user terminal through the radio frequency communication link, and transmit the communication request to the Beidou short message communication module and / or the 4G communication module for external transmission. In the embodiment of the present invention, the main control module adopts an ARM structure CPU board, which serves as the "brain" of the gateway and is responsible for coordinating the operation of the entire system. It receives data from other components and processes and sends instructions or data according to built-in software or algorithms. The CPU board is equipped with an operating system for managing hardware resources, providing device drivers, executing network protocols, etc.

[0055] The Beidou short message communication module is used to encode or decode the communication request in the short message format, and establish a short message communication link with the Beidou satellite to transmit the communication request. In the embodiment of the present invention, the Beidou short message communication module is provided with a codec and a transceiver unit in the short message format. When a short message needs to be sent, the main control module sends the communication request to the Beidou short message communication module, and the Beidou short message communication module encodes it and sends it to the Beidou satellite; when a short message response sent by the Beidou satellite is received, the Beidou short message communication module decodes it and sends it to the main control module for subsequent processing.

[0056] The 4G communication module is used to establish a 4G network transmission link with the command center to transmit communication requests. In the embodiment of the present invention, the 4G communication module is mainly used for communication with the command center, and the command center monitors the status of the emergency rescue communication gateway of the embodiment of the present invention through the 4G network transmission link. In addition, when the short message communication link fails, the communication request of the user terminal can also be transmitted to the command center through the 4G communication module, and the command center forwards it to the Beidou satellite through the Beidou ground station as a backup communication channel.

[0057] As a specific embodiment, in the step where the main control module transmits the communication request to the Beidou short message communication module and / or the 4G communication module for external transmission, the main control module preferentially transmits the communication request to the Beidou short message communication module for external transmission; when the short message communication link fails, the main control module transmits the communication request to the 4G communication module for external transmission. The embodiment of the present invention uses the 4G communication module as an emergency backup communication when the short message communication link fails, which can effectively ensure the reliability of emergency rescue communication.

[0058] Among them, the short message communication link failure is specifically determined by the following steps:

[0059] The main control module generates a communication test request;

[0060] The Beidou short message communication module encodes the communication test request in a short message format and sends the communication test request to the Beidou satellite through the short message communication link;

[0061] When the Beidou short message communication module fails to receive a communication test response returned by the Beidou satellite through the short message communication link within a preset time range, the preset fault information is transmitted to the main control module, and the main control module determines that the short message communication link is faulty based on the fault information.

[0062] The network port module is used to establish a wired transmission link with the host computer, and transmit the communication request through the wired transmission link. In the embodiment of the present invention, the network port module is used to connect to the host computer, and the equipment maintenance personnel update the configuration information and debug the fault of the emergency rescue communication gateway through the network port module.

[0063] In some embodiments, the main control module is also used to store communication requests; in this case, the stored communication requests can be exported to the host computer through the network port module. After the host computer summarizes the communication requests, it can form a form or log, and further data analysis operations can be performed in the host computer.

[0064] The power module is used to provide power supply for the gateway. In the embodiment of the present invention, the power module is integrated with a voltage stabilizing circuit, which can convert the external input voltage into the working voltage required by each module, ensure that each component works at the rated voltage and current, and avoid equipment damage or performance degradation caused by power fluctuations.

[0065] The communication architecture diagram of the gateway of the embodiment of the present invention is as follows: Figure 2As shown. Each module realizes the data transmission function from the user terminal to the Beidou satellite through the coordination and control of the main control module. The gateway of the embodiment of the present invention plays a key role in the emergency rescue system, connecting the on-site radio frequency terminal and the remote emergency command center. As a relay point for Beidou satellite communication, the emergency rescue communication gateway takes into account both equipment management and data transmission optimization, ensuring that communication requests can be quickly and efficiently transmitted to the Beidou satellite, and handling abnormalities or failures that may occur during the communication process.

[0066] The second embodiment of the present invention provides an emergency rescue communication method based on Beidou short message, which is applied to a user terminal including a radio frequency communication module, such as Figure 3 As shown, the following steps are included:

[0067] Establish a radio frequency communication link with the Beidou short message-based emergency rescue communication gateway through the radio frequency communication module;

[0068] Triggering the user terminal to generate a communication request;

[0069] The communication request is transmitted to the gateway via a radio frequency communication link.

[0070] In an embodiment of the present invention, the user terminal is used for on-site personnel to send communication requests for rescue information. In some embodiments, a button is provided on the user terminal, and when the on-site personnel need to send rescue information, the communication request can be entered and sent out by operating the button. In another embodiment, a microphone is provided on the user terminal, and the rescue information described by the on-site personnel is stored and sent out through the microphone. The user terminal of the embodiment of the present invention is provided with a communication module of 433MHz or other frequency bands, which is smaller in size and simpler in circuit, and has better portability and durability than the existing complex and bulky satellite transceiver equipment.

[0071] The third embodiment of the present invention provides an emergency rescue communication method based on Beidou short message, which is applied to the emergency rescue communication gateway based on Beidou short message of the first embodiment, such as Figure 4 As shown, the following steps are included:

[0072] Create radio frequency network coverage through the radio frequency communication module, and establish radio frequency communication links with user terminals within the radio frequency network coverage;

[0073] receiving a communication request transmitted by a user terminal via a radio frequency communication link;

[0074] Determine whether the short message communication link is faulty through the main control module;

[0075] When the short message communication link works normally, the communication request is encoded in the short message format through the Beidou short message communication module and sent to the Beidou satellite;

[0076] When the short message communication link fails, the communication request is sent to the command center through the 4G communication module, and the command center forwards the communication request to the Beidou satellite.

[0077] In the embodiment of the present invention, dual backup communication is formed by the Beidou short message communication module and the 4G communication module, which can effectively ensure the reliability of emergency rescue communication.

[0078] In some embodiments, the method of the present invention further comprises the following steps:

[0079] Receive and decode the communication request sent by the Beidou satellite through the Beidou short message communication module and / or receive the communication request sent by the command center through the 4G communication module;

[0080] Storing communication requests via the main control module;

[0081] The communication request is sent to the user terminal through the radio frequency communication module.

[0082] In addition to being able to send communication requests from user terminals to Beidou satellites, the Beidou satellite can also send communication requests to user terminals, thereby enabling the gateway of the embodiment of the present invention to achieve the effect of two-way communication. The effect of two-way communication greatly improves the flexibility and response speed of the gateway of the embodiment of the present invention, ensuring timely exchange and feedback of information in various emergency rescue scenarios, and enhancing the practicality and reliability of the gateway. Through the two-way communication mechanism, position reporting, command transmission and data transmission can be carried out more effectively, providing rescue personnel with more comprehensive and efficient communication services.

[0083] In some embodiments, the method of the embodiment of the present invention further includes the following steps:

[0084] Input the configuration information of the gateway from the host computer through the network port module. The configuration information includes the transmission protocol and configuration parameters of the RF communication module, Beidou short message communication module and 4G communication module;

[0085] The communication request stored in the main control module is transmitted to the host computer through the network port module.

[0086] The embodiment of the present invention replaces the individual management of each user terminal with the unified management of the gateway. When the communication configuration of the Beidou satellite changes, it is only necessary to change the configuration information on a few coverage gateways without adjusting the communication configuration of each user terminal, which greatly facilitates the management and maintenance costs of equipment maintenance personnel. At the same time, the stored communication requests can also be exported to the host computer through the network port module. It helps rescue personnel to form a form or log for communication requests and perform further data analysis operations in the host computer.
