[0029] Combine the following Figure 1-Figure 8 The present invention describes an asymmetric shortwave communication method, device, system, electronic equipment and storage medium.
[0030] Shortwave communication, also known as high frequency (HF) communication, uses electromagnetic waves with a frequency range of 1.6MHz~30MHz for wireless communication. As an important means of communication in the field of communication, shortwave communication has the advantages of long communication distance, strong anti-destruction, low operating cost, and easy equipment installation. It has long been widely used in message transmission, weather broadcasting, commercial communication, navigation and aviation, military command, flood control and disaster relief, etc. Traditional shortwave communication is mostly used for narrowband communication (generally 3kHz bandwidth), generally providing data transmission rates of tens to thousands of bit rates, which are used to transmit signaling, messages, voice, and small files. In recent years, with the development and maturity of shortwave technology and shortwave communication equipment, shortwave communication has developed in the direction of broadband on the one hand, providing higher bandwidth (such as 12kHz or 24kHz bandwidth) and faster data transmission rate (thousands or tens of thousands of bit rates), so as to meet the transmission needs of large files, images, faxes and other services; on the other hand, it has developed in the direction of networking and systematization, interconnecting shortwave communication equipment through shortwave networking technology, and improving the coverage and guarantee capabilities of shortwave communication through system integration.
[0031] Figure 1 It is one of the flow charts of the asymmetric shortwave communication method provided by the present invention, such as Figure 1 As shown, the asymmetric shortwave communication method is applied to fixed shortwave communication facilities, including but not limited to the following steps 101 to 103.
[0032] Step 101: Broadcast downlink service signals.
[0033] Figure 2 It is one of the structural diagrams of the asymmetric shortwave communication system provided by the present invention, such as Figure 2 As shown, the solid arrows indicate the flow direction of data and signals when broadcasting downlink service signals, and the dotted arrows indicate the flow direction of data and signals when receiving uplink response signals.
[0034] Fixed shortwave communication facilities are located on the fixed side of the shortwave broadband network communication system, and have the ability to send and receive broadband services. They generally use fixed infrastructure with high power (such as more than 1000W) and large antennas. They can be composed of equipment including but not limited to shortwave broadband signal transmitters, shortwave broadband signal receivers, and shortwave broadband signal processing equipment, etc., to achieve downlink broadband service broadcasting, high-speed data transmission, and provide downlink data transmission capabilities for large-capacity services such as pictures, faxes, and large files that cannot be met by traditional narrowband shortwave communications. Among them, the shortwave broadband signal processing equipment in the fixed shortwave communication facilities is also the first shortwave broadband signal processing equipment, and the shortwave broadband signal processing equipment in the mobile shortwave communication facilities is the second shortwave broadband signal processing equipment.
[0035] Among them, the shortwave broadband signal transmitting end includes but is not limited to a shortwave broadband transmitter and a shortwave broadband antenna; the shortwave broadband signal receiving end includes but is not limited to a shortwave receiver and a shortwave broadband antenna.
[0036] Specifically, the first shortwave broadband signal processing device in the fixed shortwave communication facility receives business data from an external system (such as a terminal on the fixed side, etc.), and its business form can be files, pictures, etc. After broadband signal modulation on these business data, a shortwave broadband downlink business signal is obtained, and it is handed over to the shortwave broadband transmitter at the shortwave broadband signal transmitting end for signal transmission, and the downlink business signal is broadcast through a wireless channel within the broadcast communication range.
[0037] Step 102: Receive an uplink response signal fed back by a shortwave radio station of a mobile shortwave communication facility within a broadcast range; the uplink response signal is a narrowband signal generated after the downlink service signal is received.
[0038] Mobile shortwave communication facilities are located on the mobile side of the shortwave broadband network communication system, and may be composed of equipment including but not limited to shortwave radio stations, second shortwave broadband signal processing equipment, and shortwave narrowband antennas. They are mostly in the form of shortwave communication vehicles and shortwave communication ships. Most mobile shortwave communication facilities that have been in service for a long time are limited by the space of the carrying facilities and cannot use large broadband antennas. They are generally equipped with smaller narrowband antennas and lower-power shortwave radio stations (such as less than 125W). Although they have the ability to receive broadband services, they do not have the ability to send broadband services and only have the ability to send narrowband services.
[0039] Specifically, after the fixed shortwave communication facility broadcasts the downlink service signal, the mobile shortwave communication facility on the motorized side within the broadcast range receives the downlink service signal of the shortwave wireless in the air through the installed shortwave radio, and the shortwave radio reports the received downlink service signal to the second shortwave broadband signal processing device. The second shortwave broadband signal processing device performs broadband data demodulation on the downlink service signal to obtain the original service data, and sends the demodulated original service data to the external system (such as the terminal on the motorized side, etc.).
[0040] After the shortwave radio station receives the downlink service signal, the second shortwave broadband signal processing device of the mobile shortwave communication facility generates an uplink response signal according to the format specified by the air interface, and sends the modulated uplink response signal to the shortwave radio station for transmission. Since the mobile shortwave communication facility does not have the ability to send broadband services, the generated uplink response signal is a narrowband signal.
[0041] The shortwave receiver at the shortwave broadband signal receiving end of the fixed shortwave communication facility on the fixed side will receive the uplink response signal fed back by the mobile shortwave communication facility within the broadcast range through the air wireless channel.
[0042] Optionally, after the shortwave radio station completes reception and successfully demodulates the downlink service signal, the second shortwave broadband signal processing device of the mobile shortwave communication facility generates an uplink response signal in accordance with the format specified by the air interface.
[0043] Optionally, the second shortwave broadband signal processing device is integrated into the shortwave radio station.
[0044] Step 103: Based on the received uplink response signal, determine whether to continue broadcasting or terminate broadcasting the downlink service signal.
[0045] The shortwave receiver in the fixed shortwave communication facility on the fixed side reports the received uplink response signal to the first shortwave broadband signal processing equipment for demodulation and signal modulation, and obtains the information carried in the uplink response signal that the mobile shortwave communication facility has completed receiving the downlink service signal. At this time, it generally represents that the communication task of the relevant current service has been completed, and the broadcast can be terminated, that is, the current downlink broadband service broadcast is stopped, without the need to end the broadcast transmission of the broadband downlink service signal by manual stop or timeout automatic stop, thereby avoiding the situation where the fixed shortwave communication facility cannot know that the corresponding mobile shortwave communication facility has completed receiving the service signal. At the same time, it avoids the problem that the fixed shortwave communication facility can only continue broadcasting within the pre-agreed time due to the inability to know the real-time situation of service reception, resulting in a waste of communication resources.
[0046] Furthermore, after the first shortwave broadband signal processing device determines that the current broadband service is sent, it sends a service response to the external system on the fixed side, thereby completing a shortwave narrowband uplink and downlink asymmetric service communication.
[0047] If a fixed shortwave communication facility wants to send a downlink service signal to a specific mobile shortwave communication facility, but the identity identification code carried in the uplink response signal received by the fixed shortwave communication facility does not match the identity identification code of the specific mobile shortwave communication facility, it is necessary to continue broadcasting until the specific mobile shortwave communication facility feeds back the uplink response signal carrying its identity identification code to the fixed shortwave communication facility and terminates the broadcast, or until the broadcast is terminated due to automatic stop due to timeout, manual stop, etc.
[0048] Optionally, the terminals of the external systems on the fixed side and the mobile side can be software or APP on platforms such as PCs, tablets, or mobile phones, which are upper computer software that can interconnect with fixed shortwave communication facilities and mobile shortwave communication facilities. Business data can be file formats on all computers, such as pictures, compressed packages, office documents, txt documents, etc. For example, a computer in the external system on the fixed side captures a photo through a camera, and sends it to the fixed shortwave communication facility through the terminal software on the computer for shortwave broadband broadcasting, thereby achieving the delivery of the picture to the mobile shortwave communication facility on the mobile side and its connected mobile users through reliable and indestructible shortwave communication means. In addition, business data can also be address book files, upgraded software compressed packages, etc.
[0049] The asymmetric shortwave communication method provided by the present invention, when the mobile shortwave communication facilities are difficult to update in time, by utilizing the shortwave radio station with narrowband service transmission capability carried thereon, constructs a two-way communication mechanism in which the mobile side can timely feed back to the fixed side a narrowband response signal regarding the completion of receiving the broadband service signal, so as to realize the reception confirmation function of the broadband service signal on the mobile side, so that the fixed side can timely decide to continue broadcasting or stop broadcasting the service signal according to the response situation of the mobile side, that is, according to the real-time reception situation of the broadband service signal, timely and automatically decide to stop broadcasting the signal in advance, and at the same time realize the asymmetric shortwave communication with the automatic broadcast stop processing function, also saves communication resources.
[0050] Based on the above embodiment, as an optional embodiment, determining to continue broadcasting or terminate broadcasting the downlink service signal based on the received uplink response signal includes: Determining the number of received uplink response signals; If the number of the signals is less than a preset number threshold, determining to continue broadcasting the downlink service signal; If the number of the signals is greater than or equal to a preset number threshold, it is determined to terminate the broadcasting of the downlink service signal.
[0051] Specifically, Figure 3 This is the second structural diagram of the asymmetric shortwave communication system provided by the present invention, combined with Figure 3 As shown in the figure, in addition to realizing asymmetric communication with a specific mobile shortwave communication facility, it is also possible to simultaneously broadcast downlink broadband services to multiple mobile shortwave communication facilities on the mobile side. The fixed shortwave communication facility sends a broadcast downlink service signal on a certain frequency, and multiple facilities simultaneously receive broadband downlink service signals on the frequency and actively feed back uplink response signals to the fixed shortwave communication facility.
[0052] The fixed shortwave communication facilities on the fixed side will pre-configure the number of mobile shortwave communication facilities that need to receive the current broadband broadcasting service, that is, pre-configure a preset number threshold.
[0053] When broadcasting a downlink service signal, the fixed shortwave communication facility determines the number of uplink response signals received in the current service at a certain period or after each uplink response signal is received, and determines whether the number of signals is less than a preset number threshold.
[0054] If the number of signals is less than the preset number threshold, the fixed shortwave communication facility continues to broadcast the downlink service signal; if it is greater than or equal to the preset number threshold, the fixed shortwave communication facility stops broadcasting the downlink service signal and completes the current service sending process. Optionally, multiple different mobile shortwave communication facilities within the broadcast range feed back uplink response signals to the fixed shortwave communication facility at different frequencies within the shortwave frequency band that are planned in advance, so as to avoid interference between different mobile shortwave communication facilities when feeding back uplink response signals.
[0055] The asymmetric shortwave communication method provided by the present invention can automatically stop the current broadband service broadcast after receiving the expected number of uplink response signals on the fixed side by pre-configuring a preset number threshold on the fixed side, thereby automatically completing the current service sending process.
[0056] Based on the above embodiment, as an optional embodiment, the uplink response signal carries an identity identification code; the identity identification code is a unique identification code of the mobile shortwave communication facility or the mobile user; the determination of continuing to broadcast or terminating broadcasting the downlink service signal based on the received uplink response signal includes: predetermining a first identity code set of the mobile shortwave communication facility and / or the mobile user that should receive the downlink service signal; Parsing the received uplink response signals to obtain a second identity identification code set; If the second identity identification code set does not completely include the first identity identification code set, determining to continue broadcasting the downlink service signal; If the second identity identification code set completely includes the first identity identification code set, it is determined to terminate the broadcasting of the downlink service signal.
[0057] Mobile users refer to mobile user terminals connected to mobile shortwave communication facilities.
[0058] Each mobile shortwave communication facility or each mobile user has a unique identification code as an identity code.
[0059] Specifically, the fixed shortwave communication facility will predetermine a collection of identity codes of mobile shortwave communication facilities or mobile users that need to receive downlink service signals of the current service, namely, a first identity code set.
[0060] While broadcasting the downlink service signal, the first shortwave broadband signal processing device parses the uplink response signals fed back by a number of mobile shortwave communication facilities, obtains the identity identification codes of the mobile shortwave communication facilities or mobile users carried in the uplink response signals, and constructs a second identity identification code set.
[0061] Further determine the inclusion relationship between the first identity identification code set and the second identity identification code set. If the second identity identification code set does not completely include the first identity identification code set, it indicates that there are still mobile shortwave communication facilities and / or mobile users that have been agreed to receive the current business data and have not yet received or have not yet received the downlink business signal, and it is necessary to continue broadcasting the downlink business signal; if the second identity identification code set completely includes the first identity identification code set, it indicates that all agreed mobile shortwave communication facilities and / or mobile users have received the current business data, and the broadcasting of the downlink business signal is terminated at this time.
[0062] The asymmetric shortwave communication method provided by the present invention can identify the response signals from different mobile users on the fixed side, monitor in real time whether all mobile shortwave communication facilities and / or mobile users have received the service, and make statistics on the service reception status, thereby automatically judging whether the current service sending process is completed and automatically deciding whether to stop the current broadband service broadcast, by determining in advance on the fixed side a collection of identity identification codes of mobile shortwave communication facilities and / or mobile users that need to receive the downlink service signal of the current service, and carrying the identification code in the uplink response signal.
[0063] As an optional embodiment, determining to continue broadcasting or terminate broadcasting the downlink service signal based on the received uplink response signal includes: predetermining a first identity code set of the mobile shortwave communication facility and / or the mobile user that should receive the downlink service signal; Determining the number of received uplink response signals; If the number of the signals is greater than or equal to a preset number threshold, determining to terminate broadcasting of the downlink service signal; If the number of the signals is less than a preset number threshold, parsing the received plurality of the uplink response signals to obtain a second identity identification code set; If the second identity identification code set completely includes the first identity identification code set, determining to terminate broadcasting the downlink service signal; If the second identity identification code set does not completely include the first identity identification code set, it is determined to continue broadcasting the downlink service signal.
[0064] As an optional embodiment, the fixed shortwave communication facility can perform security authentication and identity recognition on the mobile shortwave communication facility when selecting the frequency and establishing the link by parsing the identity identification code in the uplink response signal.
[0065] Based on the above embodiment, as an optional embodiment, the fixed shortwave communication facility includes a shortwave broadband signal transmitting end and a shortwave broadband signal receiving end; the shortwave broadband signal transmitting end includes a shortwave broadband antenna with separate transmission and reception; the shortwave broadband signal receiving end includes the shortwave broadband antenna with separate transmission and reception; The broadcast downlink service signal includes: The shortwave broadband antenna with separate transmission and reception is used to broadcast the downlink service signal; The uplink response signal fed back by the shortwave radio station of the mobile shortwave communication facility within the receiving broadcast range includes: The shortwave broadband antenna with separate transmission and reception receives the uplink response signal fed back by the shortwave radio station of the mobile shortwave communication facility within the broadcasting range.
[0066] Specifically, the shortwave broadband signal transmitting end and the shortwave broadband signal receiving end of the fixed shortwave communication facility adopt a shortwave broadband antenna with separated transmission and reception, and cooperate with the first shortwave broadband signal processing equipment and the shortwave broadband transmitter. The shortwave broadband antenna with separated transmission and reception simultaneously broadcasts the downlink service signal and receives the uplink response signal fed back by the shortwave radio station of the mobile shortwave communication facility within the broadcast range.
[0067] The asymmetric shortwave communication method provided by the present invention can realize full-duplex communication by adopting a shortwave broadband antenna with separate transmission and reception on the fixed side, thereby avoiding the inability to receive an uplink response signal when broadcasting a downlink business signal, and being able to receive feedback information from the mobile side in a timely manner. As long as it is determined that the target mobile shortwave communication facility or mobile user on the mobile side has received all the business data, the broadcast can be stopped immediately, and the reception confirmation and stop processing operations can be performed more timely, thereby avoiding waste of communication resources.
[0068] The asymmetric shortwave communication method provided by the present invention adopts a shortwave broadband antenna with separate transmission and reception on the fixed shortwave communication facilities on the fixed side as a whole, and cooperates with the first shortwave broadband signal processing equipment and the shortwave broadband transmitter to realize downlink broadband service broadcasting, realize high-speed data transmission, and provide downlink data transmission capability for large-capacity services such as pictures, faxes, and large files that cannot be satisfied by traditional narrowband shortwave communications; at the same time, a shortwave receiver is adopted on the fixed shortwave communication facilities on the fixed side to receive the narrowband response signal of the mobile side, and notify the first shortwave broadband signal processing equipment to perform service reception confirmation and stop processing; at the same time, the mobile shortwave communication facilities on the mobile side are equipped with a shortwave radio station, a shortwave narrowband antenna, and a second shortwave broadband signal processing equipment to realize the reception and processing of the downlink broadband service from the fixed side, and send the shortwave narrowband service reception confirmation to the fixed side through the transmission capability of the shortwave radio station, which not only meets the broadband service transmission demand from the fixed side to the mobile side, but also realizes the service transmission and reception linkage and information synchronization between the fixed side and the mobile side.
[0069] Furthermore, the present invention mainly proposes a method for realizing asymmetric uplink and downlink wide-narrowband communications for fixed station facilities and mobile mobile facilities frequently used in the field of modern shortwave communications in typical application environments with asymmetric antenna types, radio station types, etc. On the one hand, through the downlink broadband communication capability, it meets the shortwave high-speed data communication needs of pictures, large files, etc. that cannot be achieved by conventional shortwave narrowband communications; on the other hand, with the help of uplink narrowband response, it not only meets the actual physical conditions of the mobile facilities, but also realizes communication linkage and information synchronization with the fixed side, and can realize automated, unmanned, real-time continuous broadband business communications, providing a communication-level solution for more complex system-level transaction management and task management.
[0070] Figure 4 FIG. 2 is a flow chart of the asymmetric shortwave communication method provided by the present invention. Figure 4 As shown, the asymmetric shortwave communication method is applied to a shortwave radio station of a mobile shortwave communication facility, including but not limited to the following steps 401 and 402.
[0071] Step 401: Receive a downlink service signal broadcast by a fixed shortwave communication facility.
[0072] Step 402: Feedback an uplink response signal to the fixed shortwave communication facility, so that the fixed shortwave communication facility determines whether to continue broadcasting or terminate broadcasting the downlink service signal based on the received uplink response signal; the uplink response signal is a narrowband signal generated after receiving the downlink service signal.
[0073] It should be noted that the asymmetric shortwave communication method applied to mobile shortwave communication facilities provided by the present invention can, during specific operation, correspond one-to-one to the asymmetric shortwave communication method applied to fixed shortwave communication equipment described in any of the above embodiments, which will not be elaborated in this embodiment.
[0074] The asymmetric shortwave communication method provided by the present invention, when the mobile shortwave communication facilities are difficult to update in time, by utilizing the shortwave radio station with narrowband service transmission capability carried thereon, constructs a two-way communication mechanism in which the mobile side can timely feed back to the fixed side a narrowband response signal regarding the completion of receiving the broadband service signal, so as to realize the reception confirmation function of the broadband service signal on the mobile side, so that the fixed side can timely decide to continue broadcasting or stop broadcasting the service signal according to the response situation of the mobile side, that is, according to the real-time reception situation of the broadband service signal, timely and automatically decide to stop broadcasting the signal in advance, and at the same time realize the asymmetric shortwave communication with the automatic broadcast stop processing function, also saves communication resources.
