Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation equipment, and in particular to a method and system for transmitting water-electricity fusion data based on instant communication. Background Art

[0002] In the field of agricultural irrigation, with the rapid development of precision agriculture and intelligent irrigation technology, higher requirements are placed on the real-time, accuracy and reliability of irrigation data. Agricultural irrigation systems usually involve multiple irrigation terminals, which are distributed in vast farmlands and transmit data with the central control system to achieve real-time monitoring of key parameters such as soil moisture and crop growth status and irrigation decisions.

[0003] However, data transmission in agricultural irrigation scenarios faces many challenges. First, the farmland environment is complex and changeable, including different soil types, vegetation cover, topography and climate conditions. These factors have a significant impact on wireless communication signals, resulting in unstable data transmission rates, especially in severe weather (such as heavy rain and strong winds) and complex terrain (such as mountains and hills). The data transmission effect is greatly reduced.

[0004] Secondly, the amount of data that agricultural irrigation systems need to process is huge, especially in large-scale farmland irrigation operations, and the data transmission pressure between irrigation terminals and central control systems has increased significantly. Traditional data transmission methods often use fixed transmission parameters, which leads to low data transmission efficiency when the network is congested or the signal quality is poor, and the real-time transmission of irrigation instructions is blocked, which in turn affects irrigation effects and crop growth.

[0005] At present, the hydropower integration data in agricultural irrigation scenarios has the defects of poor signal quality and single communication mode, which leads to poor communication quality between the hydropower integration terminal and the system platform and prone to communication failures.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following will be described through specific embodiments in conjunction with the accompanying drawings of the present invention.

[0027] As described in the background technology, the current hydropower fusion data in agricultural irrigation scenarios has the defects of poor signal quality and a single communication method, which leads to poor communication quality between the hydropower fusion terminal and the system platform and is prone to communication failures.

[0028] To solve this technical problem, Figure 1 As shown, an embodiment of the present invention provides a method for transmitting hydropower fusion data based on instant messaging, which is applied to a hydropower data transmission system including a hydropower system platform and multiple hydropower fusion terminals, and includes steps S101-S104.

[0029] S101. Monitor the real-time transmission rate of the hydropower integration data between the hydropower integration terminal and the hydropower system platform.

[0030] It should be noted that if the real-time transmission rate is large, it means that the communication status between the hydropower fusion terminal and the hydropower system platform is good. If the real-time transmission rate is small, it means that the communication status between the hydropower fusion terminal and the hydropower system platform is poor, and the transmission method needs to be improved. If the real-time transmission rate is too small, it means that the communication status between the hydropower fusion terminal and the hydropower system platform is extremely poor, normal communication is impossible, and there is a communication failure, which may be affected by bad weather or complex terrain. The present invention monitors the real-time transmission rate and takes corresponding measures to ensure the communication quality between the hydropower fusion terminal and the hydropower system platform and realize instant communication.

[0031] S102: If the real-time transmission rate is greater than the first rate, the transmission method of the water-power fusion data remains unchanged.

[0032] In the embodiment of the present application, the transmission mode includes the amount of data transmitted in a single transmission and the data transmission rate of the hydropower fusion terminal.

[0033] In some embodiments, the transmission method also includes the number of retransmissions and the frequency of data transmission.

[0034] S103: If the real-time transmission rate is less than or equal to the first rate and greater than the second rate, adjusting the transmission mode based on the real-time transmission rate to achieve instant communication.

[0035] The first rate is greater than the second rate.

[0036] As a possible implementation manner, step S103 may be specifically implemented as steps S1031 - S1035 .

[0037] S1031. Based on the real-time transmission rate, adjust the data volume of the standard data packet transmitted once to obtain an adjusted data volume.

[0038] Exemplarily, the embodiment of the present invention can divide the first rate and the second rate equally, determine multiple intervals, and set a corresponding standard data packet data volume for each interval. The embodiment of the present invention can determine the adjusted data volume according to the interval corresponding to the real-time transmission rate.

[0039] S1032. Keep the data transmission rate unchanged, and send the hydropower fusion data with the adjusted data volume.

[0040] For example, for each transmission process of the hydropower fusion terminal, the hydropower fusion terminal can keep the data transmission rate unchanged, split the hydropower fusion data to be transmitted according to the data volume of the adjusted standard data packet, and send the data packet corresponding to the transmission process. After multiple transmission processes, the hydropower fusion terminal completes the transmission of the hydropower fusion data.

[0041] S1033. Monitor the transmission delay of the hydropower integration data after the transmission mode is adjusted.

[0042] S1034: If the transmission delay is less than or equal to the set duration, the data transmission rate is kept unchanged.

[0043] S1035. If the transmission delay is greater than the set duration, reduce the data transmission rate of the hydropower fusion terminal until the transmission delay is less than or equal to the set duration.

[0044] Exemplarily, after adjusting the data volume of the standard data packet, the embodiment of the present invention can monitor the transmission delay. If the transmission delay is less than or equal to the set duration, it means that the communication state is good and the data transmission rate can be kept unchanged. If the transmission delay is greater than the set duration, it means that the communication state is poor, and it is necessary to reduce the data transmission rate of the hydropower fusion terminal until the transmission delay is less than or equal to the set duration, thereby reducing the data packets during the transmission process and alleviating network congestion.

[0045] As another possible implementation manner, step S103 may be specifically implemented as steps S1036-S1039.

[0046] S1036. Monitor the completion status of the transmission of the hydropower fusion data after the transmission mode is adjusted, and record the packet loss rate during the transmission process.

[0047] S1037. For any transmission process, if the transmission is not completed during the transmission process, the retransmission mechanism is started, and the data packets that are not completed during the transmission are retransmitted according to the retransmission times.

[0048] It should be noted that incomplete transmission indicates packet loss. When a data packet transmission is incomplete, it is necessary to resend the data packet to ensure that the hydropower system platform can successfully receive it. Given the poor communication status, the hydropower fusion terminal can send the same data packet multiple times, that is, the number of retransmissions, to increase the probability that the data packet is successfully received by the hydropower system platform.

[0049] S1038: If the packet loss rate is less than or equal to the set value, the data transmission frequency of the hydropower fusion terminal is kept unchanged.

[0050] S1039: If the packet loss rate is greater than the set value, reduce the data transmission frequency of the hydropower fusion terminal until the packet loss rate is less than or equal to the set value.

[0051] In this way, the embodiment of the present invention can adjust the data transmission frequency of the hydropower fusion terminal by the packet loss rate. Appropriately reducing the transmission frequency can reduce the network burden and reduce the risk of data collision and loss. When the real-time transmission rate is high, the transmission frequency can be appropriately increased to improve the real-time performance and efficiency of data transmission.

[0052] S104. If the real-time transmission rate is less than or equal to the second rate, the transmission channel between the hydropower fusion terminal and the hydropower system platform is screened to determine the optimal transmission channel; and based on the optimal transmission channel, instant communication is performed between the hydropower fusion terminal and the hydropower system platform.

[0053] As a possible implementation method, multiple transmission channels can be established between the hydropower integration terminal and the hydropower system platform, such as 4G channels, NB-IoT, satellite communication channels, etc.

[0054] Exemplarily, the embodiment of the present invention can implement the screening of the optimal transmission channel based on steps A1-A4.

[0055] A1. Sending a first test request to the hydropower system platform through each transmission channel, and recording the sending time of the first test request; the first test request is used to request the hydropower system platform to test the transmission channel; A2. Receive the first test response sent back by the hydropower system platform, and record the receiving time of the first test response; A3. Determine the transmission delay of each transmission channel based on the sending time of the first test request and the receiving time of the first test response; A4. Determine the optimal transmission channel based on the transmission delay of each transmission channel.

[0056] In this way, the embodiment of the present invention can determine the optimal transmission channel and ensure the communication quality by measuring the transmission delay of multiple transmission channels between the hydropower fusion terminal and the hydropower system platform.

[0057] As a possible implementation method, the embodiment of the present invention can establish an Internet of Things between multiple hydropower fusion terminals, so that the hydropower fusion terminal can communicate with the hydropower system platform through the nearby hydropower fusion terminals as relays. For example, due to the influence of complex terrain such as mountainous areas and hills, the communication quality of the hydropower fusion terminal at this location is poor, and the communication with the hydropower system platform can be achieved through other hydropower fusion terminals near the location to ensure the communication quality.

[0058] Exemplarily, the embodiment of the present invention can implement the screening of the optimal transmission channel based on steps B1-B3.

[0059] B1. Sending a second test request to other hydropower fusion terminals among the multiple hydropower fusion terminals, and recording the sending time of the second test request, where the second test request is used to request other hydropower fusion terminals to test the state of the transmission channel between the terminal and the hydropower system platform; B2. Receive the second test response sent back by other hydropower fusion terminals, and record the receiving time of the second test response; the second test response includes the transmission delay between other hydropower fusion terminals and the hydropower system platform; B3. Determine an optimal transmission channel based on the sending time of the second test request, the receiving time of the second test response, and the second test response.

[0060] In this way, the embodiment of the present invention can determine the optimal transmission channel and ensure the communication quality by measuring the transmission delay of the Internet of Things composed of multiple hydropower fusion terminals.

[0061] As a possible implementation manner, after determining the optimal transmission channel, the embodiment of the present invention can realize instant communication between the hydropower fusion terminal and the hydropower system platform based on steps S1041-S1044.

[0062] S1041. Determine the next-level receiving device in the optimal transmission channel.

[0063] S1042. Determine the transmission mode of the hydropower fusion terminal based on the transmission delay of the optimal transmission channel.

[0064] S1043. Based on the data volume of the standard data packet in the transmission mode, split the hydropower fusion data to obtain multiple standard data packets.

[0065] S1044. Based on the data transmission rate and data transmission frequency in the transmission mode, transmit multiple standard data packets to the next level receiving device.

[0066] The present invention provides a method for transmitting hydropower fusion data based on instant communication. By monitoring the real-time transmission rate of hydropower fusion data between a hydropower fusion terminal and a hydropower system platform, when the real-time transmission rate is relatively high, the transmission mode is kept unchanged. When the real-time transmission rate is relatively high, the transmission mode such as the amount of data transmitted in a single transmission and the data sending rate of the hydropower fusion terminal are adjusted, so that the transmission mode adapts to the real-time transmission rate, and the instant communication between the hydropower fusion terminal and the hydropower system platform is realized. When the real-time transmission rate is too low, the optimal transmission channel between the hydropower fusion terminal and the hydropower system platform is switched to ensure the instant communication between the hydropower fusion terminal and the hydropower system platform. The present invention adaptively changes the transmission mode and the transmission channel according to the real-time transmission rate, realizes the instant communication between the hydropower fusion terminal and the hydropower system platform in the hydropower data transmission system, and improves the communication quality between the hydropower fusion terminal and the hydropower system platform.

[0067] Optionally, the method for transmitting water-power fusion data based on instant messaging provided in an embodiment of the present invention further includes steps S201-S205.

[0068] S201. Obtain historical data of the transmission rate between the hydropower fusion terminal and the hydropower system platform, and historical meteorological data of the area where the hydropower fusion terminal is located.

[0069] S202: Divide the historical data of the transmission rate and the historical meteorological data into time windows, and determine the transmission rate and meteorological data of each time window.

[0070] S203. Based on the transmission rate and meteorological data of each time window, correlation analysis and data fitting are performed to obtain a fitting function between the transmission rate between the hydropower fusion terminal and the hydropower system platform, and the meteorological data of the area where the hydropower fusion terminal is located.

[0071] S204, determining a time-sharing transmission strategy for the hydropower fusion data based on the meteorological data of the forecast period in the area where the hydropower fusion terminal is located, a fitting function, and a real-time transmission rate.

[0072] As a possible implementation manner, step S204 may be specifically implemented as steps S2041 - S2042 .

[0073] S2041. Based on the meteorological data of the prediction period and the fitting function, the predicted transmission rate of each time window in the prediction period is predicted.

[0074] S2042. Based on the predicted transmission rate of each time window within the prediction period and the real-time transmission rate, the hydropower fusion data is allocated and a time-sharing transmission strategy is determined.

[0075] In some embodiments, the time-sharing transmission strategy includes the amount of water-power fusion data to be transmitted within each prediction time window.

[0076] In this way, the embodiment of the present invention can use predicted weather data to predict the transmission rate of the hydropower fusion terminal, so as to formulate a corresponding time-sharing transmission strategy, so that the entire amount of hydropower fusion data can be sent to the hydropower system platform in a timely and accurate manner, thereby improving the real-time and integrity of the hydropower fusion data.

[0077] S205. Based on the time-sharing transmission strategy of the hydropower fusion data, the hydropower fusion data is sent to the hydropower system platform.

[0078] As a possible implementation manner, step S205 may be specifically implemented as steps S2051 - S2055 .

[0079] S2051. Determine the total amount of hydropower fusion data to be sent by the hydropower fusion terminal.

[0080] S2052: Based on the real-time transmission rate, the time-sharing transmission strategy is updated to determine the updated time-sharing transmission strategy.

[0081] S2053: Based on the updated time-sharing transmission strategy and the total amount of water-power fusion data to be sent, data allocation is performed to determine the amount of data to be transmitted in the current time window.

[0082] S2054: Based on the amount of data to be transmitted in the current time window and the priority of various types of hydropower fusion data, determine the data to be transmitted in the current time window.

[0083] S2055. Send the data to be transmitted based on the transmission mode corresponding to the real-time transmission rate.

[0084] In this way, the embodiment of the present invention can update the time-sharing transmission strategy based on the real-time communication status between the hydropower fusion terminal and the hydropower system platform, so that a suitable transmission rate can be adopted between the hydropower fusion terminal and the hydropower system platform to transmit a suitable amount of data, thereby maximizing the data transmission rate while reducing network congestion and improving the communication quality between the hydropower fusion terminal and the hydropower system platform.

[0085] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0088] The communication module 301 is used to monitor the real-time transmission rate of the hydropower integration data between the hydropower integration terminal and the hydropower system platform.

[0089] The processing module 302 is used to keep the transmission mode of the hydropower fusion data unchanged if the real-time transmission rate is greater than the first rate, and the transmission mode includes the amount of data transmitted in a single transmission and the data sending rate of the hydropower fusion terminal; if the real-time transmission rate is less than or equal to the first rate and greater than the second rate, adjust the transmission mode based on the real-time transmission rate to achieve instant communication; the first rate is greater than the second rate; if the real-time transmission rate is less than or equal to the second rate, screen the transmission channel between the hydropower fusion terminal and the hydropower system platform to determine the optimal transmission channel; and based on the optimal transmission channel, perform instant communication between the hydropower fusion terminal and the hydropower system platform.
