Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
The technical solution of the present application will be described below by way of specific examples.
Referring to fig. 1, a schematic flow chart illustrating steps of a ship navigation data transmission method according to an embodiment of the present application is shown, which may specifically include the following steps:
s101, acquiring navigation data of the ship in the navigation process of the ship, wherein the navigation data has corresponding acquisition time.
The method can be applied to terminal equipment which can be electronic equipment installed on a ship and capable of achieving communication with a ship management platform. The ship management platform may be a platform for performing unified scheduling and management on a plurality of ships.
In the embodiment of the present application, the navigation data may include position information of the ship during navigation, such as longitude and latitude where the ship is currently located; the navigation data may also include status information of each device on the ship, such as operation time, rotation speed, oil pressure and other data of an engine on the ship, or early warning information, warning information and the like of a ship safety system.
The navigation data can be acquired by corresponding equipment. For example, the position information may be collected by the positioning device and then sent to the terminal device by the positioning device; alternatively, a positioning module may be integrated into the terminal device, and the positioning module may collect position information of the ship during the navigation. The state information of each device on the ship can be acquired by devices such as a sensor and then sent to the terminal device by the sensor; or, each device on the ship may be modified, a data communication channel between each modified device and the terminal device is established, and each device directly sends the respective state information to the terminal device.
In the embodiment of the application, the terminal equipment can acquire navigation data according to a certain frequency. For example, the terminal device may collect the voyage data every 5 seconds, or every 10 seconds. The acquired voyage data may have a corresponding acquisition time.
S102, monitoring the communication state between the ship and the ship management platform, wherein the communication state comprises an online state or an offline state.
Typically, communication between the vessel and the vessel management platform may be via a wireless network. For example, 4G, 5G, etc. wireless public network networks. Therefore, in some navigation areas, there may be situations where the wireless network has no signal or the signal is weak enough to transmit navigation data completely and accurately.
In the embodiment of the application, in order to ensure the reliability of the navigation data transmission, the terminal device may monitor the communication state between the ship and the ship management platform in real time, where the communication state is between the terminal device itself and the ship management platform. Generally, the communication status may include an online status or a wireless status. The online state may be a state in which the communication connection between the terminal device and the ship management platform is stable and reliable, and the data transmission rate between the terminal device and the ship management platform is greater than or equal to a certain rate threshold. Under the on-line state, the terminal equipment can timely and accurately transmit navigation data to the ship management platform. The offline state may be a state in which the communication connection between the terminal device and the ship management platform is disconnected, or the communication connection between the terminal device and the ship management platform is still established, but under the communication connection, the data transmission rate between the terminal device and the ship management platform is low, and data transmission cannot be performed in time.
In a possible implementation manner of the embodiment of the application, the communication state between the ship and the ship management platform may be determined by monitoring a communication rate between the ship and the ship management platform, that is, a network rate of a wireless network between the terminal device itself and the ship management platform. In this way, when the communication connection between the vessel and the vessel management platform is broken, the rate of communication between the two can be considered to be zero.
Therefore, when the communication rate between the ship and the ship management platform is monitored, if the communication rate is greater than or equal to the preset rate threshold, the communication state between the ship and the ship management platform can be determined to be an online state. Under the state, the terminal equipment can transmit the navigation data to the ship management platform timely and completely. If the monitored communication rate is higher than the preset rate threshold, the communication state between the ship and the ship management platform can be judged to be an offline state. The offline state includes two situations that the communication connection between the ship and the ship management platform is completely disconnected, and the communication connection is maintained before, but the data transmission rate under the communication connection is less than the preset rate threshold value.
It should be noted that the preset rate threshold may be determined experimentally. For example, according to the type of the navigation data to be transmitted and the size of the data packet, the lowest network speed required for timely and completely transmitting the navigation data is determined through a plurality of tests.
If the current communication state is the online state, the terminal device may execute S103, and transmit the navigation data to the ship management platform; if the current communication state is the offline state, the terminal device may first execute S104, mark the transmission state of the navigation data as untransmitted, and store the untransmitted navigation data.
S103, transmitting the navigation data to the ship management platform.
When the communication state between the ship and the ship management platform is an online state, the terminal device can be considered to be capable of transmitting the navigation data to the ship management platform timely and completely. At this time, the terminal device can directly transmit the acquired navigation data.
In a possible implementation manner of the embodiment of the application, in order to ensure reliability of transmission of the navigation data, after the terminal device transmits the navigation data, whether confirmation information returned by the ship management platform for the navigation data that has performed the transmission operation is received may also be determined. The confirmation information may be response information fed back to the terminal device by the ship management platform after receiving the voyage data, and is used for indicating that the ship management platform has received the voyage data.
In this embodiment, after transmitting the navigation data to the ship management platform, the terminal device may mark the transmission state of the navigation data as transmitted if receiving the confirmation information returned by the ship management platform. Otherwise, if the terminal device does not receive the confirmation information for the navigation data, the terminal device may consider that a fault occurs in the process of transmitting the navigation data, and the navigation data is not accurately transmitted to the ship management platform and needs to be retransmitted.
In a possible implementation manner of the embodiment of the application, the terminal device may directly perform a transmission operation again for the navigation data that needs to be retransmitted. Alternatively, the terminal device may mark the transmission status of the navigation data as not transmitted. And for the navigation data which is not transmitted, the terminal equipment can also store the navigation data, wait for the proper subsequent time and then retransmit the navigation data.
And S104, marking the transmission state of the navigation data as non-transmission and storing the non-transmission navigation data.
When the communication state between the ship and the ship management platform is an off-line state, it can be considered that the terminal device cannot transmit the navigation data to the ship management platform timely and completely. At this time, the terminal device may mark the transmission state of the collected navigation data as not transmitted. And for the navigation data which is not transmitted, the terminal equipment can store the navigation data, and transmit the navigation data after the communication state between the ship and the ship management platform is converted into the online state.
And S105, after the communication state is changed from the off-line state to the on-line state, transmitting the navigation data of which the transmission state is not transmitted to the ship management platform based on the transmission state and the acquisition time.
In the embodiment of the application, the communication state between the ship and the ship management platform is changed from the off-line state to the on-line state, which means that the communication disconnected before restores the normal connection; or the communication speed between the ship and the ship management platform is restored to be higher than the preset threshold value. After the offline state is changed into the online state, the terminal equipment can reissue the stored navigation data which is not transmitted and transmit the stored navigation data to the ship management platform again.
When the non-transmitted navigation data is reissued, the terminal equipment can perform the reissuing according to the acquisition time of each navigation data.
In one possible implementation manner of the embodiment of the present application, as shown in fig. 2, the process of transmitting untransmitted navigation data to the ship management platform based on the transmission state and the acquisition time may include the following sub-steps S1051 to S1052:
s1051, searching all the navigation data which are not transmitted in the transmission state.
And S1052, sequentially transmitting all the navigation data which are not transmitted in the transmission state to the ship management platform according to the sequence of the acquisition time.
In the embodiment of the application, the terminal device can search all the navigation data which are not transmitted, and sequentially transmit the navigation data according to the sequence of the acquisition time. Specifically, after all the untransmitted navigation data are searched, the terminal device may preferentially transmit the navigation data with the earliest acquisition time. In the case of transmitting one piece of navigation data, the terminal device may confirm and transmit the piece of navigation data with the earliest acquisition time again for the remaining pieces of navigation data. By repeating the above operations, the terminal device can transmit all the untransmitted navigation data to the ship management platform in the order of the acquisition time from morning to evening.
In a possible implementation manner of the embodiment of the application, after all the navigation data which are not transmitted are searched, the terminal device may preferentially transmit a piece of navigation data with the latest acquisition time. In the case of transmitting one piece of navigation data, the terminal device may confirm and transmit the latest piece of navigation data again for the remaining pieces of navigation data. By repeating the above operations, the terminal device can transmit all the untransmitted navigation data to the ship management platform in the order of the acquisition time from late to early. Therefore, the ship management platform can preferentially receive the navigation data with the acquisition time closer to the current moment.
In a possible implementation manner of the embodiment of the present application, as shown in fig. 3, after searching all navigation data whose transmission status is not transmitted, the terminal device may further perform the following steps S1511-S1522:
and S1511, determining the acquisition interval of the navigation data.
S1512, determining the data continuity between all the navigation data which are not transmitted in the transmission state according to the acquisition interval.
S1513, the navigation data with the data continuity is packaged into a data section, and the acquisition time of the data section is the earliest acquisition time in the contained navigation data.
In the embodiment of the application, the acquisition interval of the navigation data can be determined according to the frequency of acquiring the navigation data by the terminal equipment. For example, if the terminal device is required to collect the voyage data 12 times per minute, it can be considered that the terminal device is the voyage data collected at the collection interval of once every 5 seconds. The acquisition interval in this case is also 5 seconds.
According to the acquisition interval of the navigation data, whether data continuity exists between all the navigation data which are not transmitted can be determined. The data continuity may refer to whether a plurality of pieces of navigation data are continuously acquired.
Illustratively, taking the acquisition interval as 5 seconds as an example, if the untransmitted navigation data includes the following five pieces:
navigation data 1: 2021-10-19, 17:13:05, no transmission;
navigation data 2: 2021-10-19, 17:13:25, no transmission;
navigation data 3: 2021-10-19, 17:13:30, no transmission;
navigation data 4: 2021-10-19, 17:13:35, no transmission;
navigation data 5: 2021-10-19, 17:13:55, no transmission.
It can be confirmed that the above-mentioned navigation data 2, 3 and 4 have data continuity according to the collection interval. That is, after acquiring the navigation data 2, the navigation data obtained by the data acquisition operation performed by the terminal device is the navigation data 3, and after acquiring the navigation data 3, the navigation data obtained by the data acquisition operation performed again by the terminal device is the navigation data 4.
For navigation data with data continuity, the terminal device may encapsulate it into data segments. For example, the above-described navigation data 2, navigation data 3, and navigation data 4 are packaged into a data segment 1. Thus, when these navigation data are subsequently transmitted, they can be transmitted in the form of data segments.
The plurality of pieces of voyage data packed into the data segments are also essentially untransmitted voyage data and may have corresponding acquisition times.
In an embodiment of the present application, the acquisition time of the data segment may be the earliest acquisition time in the contained navigation data. For example, in the above example, the acquisition time of the voyage data 2 is 17:13:25, the acquisition time of the voyage data 3 is 17:13:30, and the acquisition time of the voyage data 4 is 17:13:35, with the acquisition time 17:13:25 of the voyage data 2 being the earliest. Therefore, the time can be taken as the acquisition time of the encapsulated data segment. That is, the acquisition time of the data segments is 17:13: 25.
Thus, the five pieces of voyage data in the above example can be expressed as:
navigation data 1: 2021-10-19, 17:13:05, no transmission;
data segment 1: navigation data 2, navigation data 3, navigation data 4, 2021-10-19, 17:13:25, which are not transmitted;
navigation data 5: 2021-10-19, 17:13:55, no transmission.
Subsequently, when transmitting the navigation data, if the terminal device transmits the navigation data in the order of the acquisition time from early to late, the navigation data 1 in the above example may be transmitted first, then the data segment 1 is transmitted, and then the navigation data 5 is transmitted.
In the embodiment of the present application, after the communication state between the ship and the ship management platform is changed from the offline state to the online state, there may be other data that needs to be sent. For example, the navigation data collected at the current time. Therefore, when the terminal device sequentially transmits all the navigation data which are not transmitted to the ship management platform according to the sequence of the acquisition time, whether the current time is the communication idle time or not can be firstly determined. If the current moment is the communication idle time, the terminal equipment can execute the action of sequentially transmitting all the navigation data which are not transmitted to the ship management platform according to the sequence of the acquisition time. Otherwise, if the current time is not the communication idle time, the terminal device may wait for the communication idle time to be reached and then execute the action of transmitting the navigation data. In this way, it can be guaranteed with priority that important data is transmitted with priority.
In the embodiment of the application, after the terminal device acquires the navigation data in the navigation process of the ship, the navigation data can be processed in a targeted manner according to the communication state between the ship and the ship management platform. If the current communication state is an online state, the terminal equipment can directly transmit the navigation data to the ship management platform, and the real-time performance of data transmission is guaranteed. If the current communication state is an off-line state, the terminal equipment can store the navigation data after marking the navigation data, and after the communication state is changed from the off-line state to an on-line state, the terminal equipment can send the navigation data which is not transmitted again, so that the navigation data at all times can be received by the ship management platform. By the method, reliability and integrity of navigation data transmission are improved.
It should be noted that, the sequence numbers of the steps in the foregoing embodiments do not mean the execution sequence, and the execution sequence of each process should be determined by the function and the inherent logic of the process, and should not constitute any limitation on the implementation process of the embodiments of the present application.
For convenience of understanding, the ship navigation data transmission method provided by the embodiment of the present application is described below with reference to a specific example.
Fig. 4 is a schematic diagram illustrating a transmission process of ship positioning information according to an embodiment of the present application. That is, fig. 4 is a description of an embodiment of the present application taking ship positioning information as an example.
In fig. 4 (a), a process of transmitting the ship location information in an online state is shown. After the terminal equipment collects the ship positioning information, the ship positioning information can be directly transmitted to the ship management platform based on the communication connection between the ship and the ship management platform. After the ship management platform receives the ship positioning information, the ship positioning information can be confirmed. For example, the ship management platform may feed back confirmation information to the terminal device to inform the terminal device that the platform has successfully received the ship positioning information. On the other hand, the terminal equipment can store the ship positioning information after acquiring the ship positioning information. After receiving the confirmation information fed back by the ship management platform, the terminal device may update the transmission state of the ship positioning information to be transmitted.
Fig. 4 (b) shows a process in which the terminal device transmits the ship positioning information after the communication state is changed from the offline state to the online state, that is, a process in which the terminal device reissues the ship positioning information. As shown in fig. 4, in this process, the terminal device may search for the ship positioning information that is not transmitted, and then transmit these data to the ship management platform according to the sequence of the acquisition time. Similarly, after the ship management platform receives the data, the data can be confirmed, and confirmation information can be fed back to the terminal device. After receiving the confirmation information fed back by the ship management platform, the terminal device may update the transmission state of the ship positioning information to be transmitted until all the untransmitted propagation positioning information is transmitted to the ship management platform.
