[0036] Ship is a general term for various vessels, which are vehicles that can sail or anchor in waters for transportation or operations. Ships are usually equipped with sensors to monitor the safety status of the ship. The ship data collected by the sensors can be sent to the monitoring device for users to view. In related technologies, ship data is often sent to the monitoring device at a fixed data transmission frequency. The transmission method lacks flexibility and fails to meet the viewing needs of users, making it difficult to ensure the safety status of the ship.

[0037] To this end, the present application proposes a data processing method, which is applied to a processing unit, such as Figure 1A-Figure 1CThe data processing system 100 shown in the figure includes a ship 110, a processing unit 120 and a monitoring device 130. The ship 110 is equipped with a sensor 111, which can be used to collect ship data. The processing unit 120 is connected to the sensor 111 and the monitoring device 130 for communication. The communication connection may include but is not limited to a wired connection and / or a wireless connection; the wireless connection may include but is not limited to a Bluetooth connection, WiFi, 4G, 5G connection. In addition, Figure 1A As shown, a communication connection can be directly established between the processing unit 120 and the sensor 111, and between the processing unit 120 and the monitoring device 130. Alternatively, as Figure 1C As shown, the data processing system 100 may further include a server 150, and the server 150 may be respectively connected to the processing unit 120 and the monitoring device 130 for communication. In this way, the processing unit 120 and the monitoring device 130 may exchange data through the server 150.

[0038] like Figure 1B As shown, the data processing system 100 may further include a storage unit 140. The storage unit 140 may be communicatively connected to the processing unit 120 and to the sensor 111. The ship data collected by the sensor 111 may be stored in the storage unit 140.

[0039] Of course, the data processing system 100 may also include a storage unit 140 and a server 150. This application does not limit this.

[0040] In some embodiments, the ship 110 may be an unmanned ship that operates automatically, or a manned ship that requires human piloting. This application does not limit this.

[0041] In some embodiments, the processing unit 120 may be a processor of the ship 110, that is, the processing unit 120 is mounted on the ship 110. In addition to executing a data processing method provided in the present application, the processing unit 120 may also execute other operation instructions of the ship 110, such as navigation instructions, berthing instructions, etc.

[0042] In other embodiments, the processing unit 120 may be a hardware device independent of the ship 110. The processing unit 120 may be mounted on the ship 110, or may be separated from the ship 110, for example, set on land. The processing unit 120 executes a data processing method provided in the present application, and the processor of the ship executes the operation instructions of the ship 110, such as navigation instructions, mooring instructions, etc.

[0043] In some embodiments, the monitoring device 130 may include, but is not limited to, a computer, a laptop computer, a cellular phone, a camera phone, a smart phone, a personal digital assistant, or a server, etc., which are devices with data processing capabilities.

[0044] A data processing method provided by the present application may include: Figure 2 Steps shown:

[0045] Step 210: monitoring trigger information when sending the ship data collected by the sensor to the monitoring device at the first transmission frequency;

[0046] Among them, the sent ship data is used for users to view through the monitoring device; the trigger information is used to trigger the change of data sending frequency; the trigger information is sent by the monitoring device when the user views the ship data, and / or is generated when the ship data indicates that the ship is in a dangerous state.

[0047] Step 220: When trigger information is detected, the ship data is sent to the monitoring device at a second sending frequency; the first sending frequency is lower than the second sending frequency.

[0048] Regarding the process of the processing unit sending the ship data to the monitoring device, in some embodiments, such as Figure 1A As shown, the processing unit 120 can directly read the collected ship information from the sensor 111, and then send it to the monitoring device 130. The processing unit 120 can adjust the data collection frequency of the sensor 111 so that the data collection frequency matches the data transmission frequency. The matching of the data collection frequency and the data transmission frequency may include: the data collection frequency is the same as the data transmission frequency, or the data collection frequency is higher than the data transmission frequency.

[0049] In other embodiments, Figure 1B As shown, the processing unit 120 can read the ship data from the storage unit 140 and send the ship data to the monitoring device 130. The data acquisition frequency of the sensor 111 can be adjusted by the processing unit 120 to match the data transmission frequency. The matching of the data acquisition frequency and the data transmission frequency may include: the data acquisition frequency is the same as the data transmission frequency, or the data acquisition frequency is higher than the data transmission frequency. The sensor 111 can also perform data acquisition at a fixed data acquisition frequency, but the data acquisition frequency should be greater than or equal to the second transmission frequency.

[0050] Furthermore, in some embodiments, Figure 1A As shown, a communication connection is directly established between the processing unit 120 and the monitoring device 130 , and the ship data can be directly sent to the monitoring device 130 through the communication connection.

[0051] In other embodiments, Figure 1CAs shown, the processing unit 120 can send the ship data to the monitoring device 130 through the server 150. In this embodiment, after the processing unit 120 sends the ship data to the server 150, the server 150 can process the ship data received within a preset time period to obtain a processing result. The above processing may include but is not limited to summary processing, analysis processing, etc. For example, the ship data within a preset time period is summarized and processed to obtain a data change trend chart; for example, the ship data within a preset time period is analyzed to obtain the data change speed, etc., to indicate the urgency of the data change. Subsequently, the server 150 can send the ship data and the processing results to the monitoring device 130 for the user to review.

[0052] The present application provides a data processing method, after the sensor collects the ship data, the processing unit can send the ship data to the monitoring device at a lower first transmission frequency. The user can view the ship data through the monitoring device, so the monitoring device can monitor whether the ship data viewing behavior occurs. When the monitoring device monitors that the user views the ship data, trigger information can be sent to the processing unit, so that the processing unit increases the data transmission frequency to the second transmission frequency.

[0053] In addition, when the ship data indicates that the ship is in a dangerous state, trigger information can be generated to enable the processing unit to increase the data transmission frequency to the second transmission frequency. The sensor and / or the processing unit can determine whether the ship data indicates that the ship is in a dangerous state, or other devices can make the determination.

[0054] If the processing unit is mounted on a ship, including the case where the processing unit is the processor of the ship, and the case where the processing unit is independent of the ship, that is, the processing unit belongs to the shipboard equipment, when the monitoring device detects that the user is viewing the ship data and then sends a trigger message to the processing unit, the ship passively increases the sending frequency of the ship data in a timely manner to meet the user's viewing needs. When the sensor and / or processing unit determines that the ship data indicates that the ship is in a dangerous state and then generates a trigger message, the ship actively increases the sending frequency of the ship data to allow the user to grasp the state of the ship in real time. In this way, when the ship meets different conditions, it can flexibly use a suitable sending frequency to send ship data to the monitoring device, and has the function of actively and passively adjusting the data sending frequency, which can not only meet the user's viewing needs, but also ensure the safety of the ship.

[0055] The working mode of the ship can be divided into a low power mode and a normal mode. In some embodiments, the first transmission frequency can be the data transmission frequency in the low power mode; and the second transmission frequency can be the data transmission frequency in the normal mode. Compared with the ship in the navigation state, when the ship is in the moored state, the ship itself and the surrounding environment change less, so the ship can enter the low power mode and send ship data to the monitoring device at a smaller first transmission frequency. In addition, when the power of the ship is lower than the preset power threshold, the ship can also enter the low power mode and send ship data to the monitoring device at a smaller first transmission frequency. That is, when the ship is in the moored state; and / or the power of the ship is lower than the preset power threshold, the processing unit can send data at the first transmission frequency. By triggering the low power mode, the power consumption in the data transmission link can be saved to extend the ship's endurance.

[0056] When the processing unit detects the trigger information, the sending frequency of the ship data is increased from the first sending frequency to the second sending frequency. In some embodiments, if the user stops viewing the ship data, and / or the ship data indicates that the ship is in a safe state, the processing unit can restore the sending frequency of the ship data to the first sending frequency to save power consumption and extend the endurance of the ship.

[0057] The ship data may include multiple categories, including but not limited to ship temperature data, ship water level data, ship humidity data, ship position data, ship sway data, ship video data, etc. In some embodiments, the processing unit sends the ship data to the monitoring device at a first transmission frequency, which may include: Figure 3 Steps shown:

[0058] Step 310: determining first category of ship data from multiple categories of ship data based on environmental information of the environment in which the ship is located;

[0059] Step 320: Send the first category of ship data to the monitoring device at a first transmission frequency.

[0060] The environmental information may be obtained by sensors carried outside the ship, or may be sent to the ship by other devices such as a server via the Internet. This application does not make any limitation here.

[0061] As an example, if the environmental information indicates that the ambient temperature exceeds a preset ambient temperature range, it is determined that the first category of ship data includes ship temperature data. When the ambient temperature exceeds the ambient temperature range, the temperature of the environment in which the ship is located may be too high or too low. Too high or too low ambient temperature may cause damage to ship parts. Even when the ambient temperature is too low, the water surface may freeze. If the ship is moored or operating in the water, ice on the water surface may cause damage to the ship. Therefore, when the ambient temperature exceeds the ambient temperature range, the ship temperature data may be sent to the monitoring device at a first sending frequency.

[0062] As an example, if the environmental information indicates that the ship is in a rainy environment, it is determined that the first category of ship data includes ship water level data. The ship can be connected to the Internet to obtain weather information in the area where it is located. When the weather information indicates that it is raining in the area where the ship is located, rainwater may accumulate in the cabin or on the deck. The accumulated water may cause water to enter the ship's parts, directly causing serious damage to the circuits and electrical components. When the accumulated water reaches a certain weight, it may even cause the ship to sink. Therefore, when the environmental information indicates that the ship is in a rainy environment, the ship water level data can be sent to the monitoring device at the first sending frequency.

[0063] As an example, if the environmental information indicates that the environmental humidity is higher than a preset environmental humidity threshold, it is determined that the first category of ship data includes ship humidity data. When the environmental humidity is too high, water droplets may be attached to ship parts, especially when water droplets appear at the contact points of electrical components, which may cause oxidation and corrosion of the parts in a short period of time, resulting in damage to the ship parts. Therefore, when the environmental information indicates that the environmental humidity is too high, the ship humidity data may be sent to the monitoring device at the first sending frequency.

[0064] As an example, if the environmental information indicates that the water flow speed in the waters where the ship is located is greater than a preset speed threshold, it is determined that the first category of ship data includes ship position data. When the water flow speed in the waters where the ship is located is too high, then regardless of whether the ship is in a working state or a moored state, the ship may move with the movement of the water flow, resulting in the loss of the ship. Because, in order to prevent the loss of the ship, when the water flow speed is too high, the ship can obtain the ship position data through the onboard positioning module and send the ship position data to the monitoring device at a first transmission frequency.

[0065] As an example, if the environmental information indicates that the environmental wind speed is greater than a preset wind speed threshold, it is determined that the first category of ship data includes ship sway data. When the environmental wind speed is too high, large waves may be generated in the waters where the ship is located. Waves can cause the ship to shake, and when the waves are too large, they may even cause the ship to capsize, causing damage to the ship. Therefore, in order to prevent the ship from capsizing, when the environmental wind speed is too high, the ship can obtain inertial data as ship sway data through the onboard inertial measurement unit (Inertial Measurement Unit, IMU) to characterize the degree of sway of the ship, and send the ship sway data to the monitoring device at a first sending frequency.

[0066] For example, if the environmental information indicates that the ship is at night, it is determined that the first category of ship data includes ship video data. At night, ship theft may occur, so the ship may be equipped with a camera to shoot at night and send the ship video data to the monitoring device at a first transmission frequency. The shooting device may include but is not limited to an infrared shooting device suitable for night shooting; the ship video data may include but is not limited to infrared video data.

[0067] For other ship data except the first category of ship data, in some embodiments, the other ship data may not be sent to the monitoring device. In other embodiments, the other ship data may be sent to the monitoring device at a third sending frequency that is smaller than the first sending frequency.

[0068] This embodiment determines the first category of ship data based on the environmental information of the environment in which the ship is located, and sends the first category of ship data to the monitoring device at a first sending frequency. On the one hand, ship data that may affect the safety of the ship can be selected from a variety of ship data and sent in a targeted manner so that the user can understand the status of the ship. On the other hand, although the environment in which the ship is located may cause damage to the ship, it does not mean that the ship is about to be damaged. For example, the ship may be equipped with devices to cope with harsh environments, including but not limited to water drainage outlets, dehumidification devices, cooling devices, etc. Feedback of ship data to users at a lower first sending frequency allows users to understand the status of the ship without consuming too much electricity.

[0069] As described above, when it is detected that a user is viewing ship data, the monitoring device may send a trigger message to the processing unit to increase the frequency of sending ship data. In some embodiments, when it is detected that the viewing frequency of the user viewing the ship data is higher than a preset viewing frequency threshold, the monitoring device may send a trigger message to the processing unit. If the user views the ship data less frequently, the first sending frequency can meet the user's viewing needs; but when the viewing frequency exceeds the threshold, the first sending frequency can no longer meet the user's viewing needs, and the data sending frequency may be increased to the second sending frequency.

[0070] In some embodiments, the monitoring device may include at least one display interface, and the display interface may be used to display ship data. In this way, the viewing frequency of the above-mentioned user viewing the ship data is higher than the preset viewing frequency threshold, which may include: the refresh frequency of the ship data displayed on the display interface is greater than the preset refresh frequency threshold. The refresh frequency of the ship data in the display interface can represent the viewing frequency of the user viewing the ship data. As an example, the display interface may include a refresh frequency adjustment control. The user adjusts the refresh frequency of the ship data by adjusting the control. As another example, the refresh frequency of the ship data may be a first fixed frequency. When the display time of the display interface, or the time the user stays on the display interface exceeds the preset time threshold, it is considered that the viewing frequency of the user viewing the ship data is higher than the preset viewing frequency threshold, and then the refresh frequency of the ship data can be adjusted from the first fixed frequency to the second fixed frequency. Correspondingly, the data transmission frequency is also adjusted from the first transmission frequency to the second transmission frequency.

[0071] In this embodiment, the monitoring device can send trigger information to the processing unit according to the refresh frequency of the ship data on the display interface to adjust the sending frequency of the ship data, so that the ship can timely increase the sending frequency of the ship data to meet the user's viewing needs.

[0072] As described above, the ship data may include multiple categories, so the monitoring device may display multiple categories of ship data through one or more display interfaces, and each display interface may display some or all categories of ship data. In some embodiments, the trigger information sent by the monitoring device to the processing unit may carry the category information corresponding to the ship data displayed on the current display interface. In this way, the above step 220 may include sending the ship data to the monitoring device at the second sending frequency when the trigger information is detected. Figure 4 Steps shown:

[0073] Step 221: when trigger information is detected, determining ship data of a second category from multiple categories of ship data based on category information carried in the trigger information;

[0074] Step 222: Send the second category of ship data to the monitoring device at a second transmission frequency.

[0075] The processing unit may determine the second category of ship data according to the category information carried by the trigger information, and the second category of ship data may be the ship data displayed in the current display interface. The second category of ship data is sent to the monitoring device at the second sending frequency, and other ship data except the second category of ship data may continue to be sent to the monitoring device at the first sending frequency, or may not be sent to the monitoring device.

[0076] In this embodiment, the processing unit sends the second category of ship data to the monitoring device at a second sending frequency, and specifically increases the sending frequency of the ship data that the user needs to view, saving the overhead of transmitting other ship data and meeting the user's viewing needs with fewer resources.

[0077] As mentioned above, when the ship data indicates that the ship is in a dangerous state, trigger information can be generated to increase the frequency of sending the ship data. The ship data may include but is not limited to ship temperature data, ship water level data, ship humidity data, ship position data, ship sway data, ship video data, etc. The ship data indicates that the ship is in a dangerous state, including one or more of the following situations:

[0078] The ship temperature data indicates that the ship temperature exceeds the preset temperature range. When the ship temperature exceeds the preset temperature range, the ship temperature may be too high or too low. Too high or too low a ship temperature may cause the ship parts to work at an inappropriate working temperature, resulting in damage to the ship parts. If the ship parts are damaged, the ship may be in a dangerous state. Therefore, when the ship temperature data indicates that the ship temperature exceeds the preset temperature range, the ship may be in a dangerous state.

[0079] The ship water level data indicates that the ship water level is higher than the preset high water level threshold. When there is too much water in the cabin or on the deck, it may cause water to enter the ship parts, directly causing serious damage to the circuits and electrical components. When the accumulated water reaches a certain weight, it may even cause the ship to sink. Therefore, when the ship water level data indicates that the ship water level is higher than the preset high water level threshold, the ship may be in a dangerous state.

[0080] The ship humidity data indicates that the ship humidity is greater than the preset humidity threshold. When the ship humidity is too high, water droplets may adhere to the ship parts, especially when water droplets appear at the contact points of electrical components, which may cause oxidation and corrosion of the parts in a short period of time, resulting in damage to the ship parts. Therefore, when the ship humidity data indicates that the ship humidity is greater than the preset humidity threshold, the ship may be in a dangerous state.

[0081] The ship weight data indicates that the ship weight is greater than a preset overweight threshold. When a ship is overloaded, it may cause the ship to sink. Therefore, when the ship weight data indicates that the ship weight is greater than a preset overweight threshold, the ship may be in a dangerous state.

[0082] The ship's position data indicates that the displacement of the ship is greater than the preset distance threshold. When the ship is moored, it can be anchored by an anchor or other floating tools on the water to prevent the ship from moving with the water flow. The ship can obtain the ship's position data through the onboard positioning module. When the displacement of the ship is greater than the preset distance threshold, it indicates that the ship has moved a long distance. If it is not handled in time, it may cause the ship to be lost. Therefore, when the ship's position data indicates that the displacement of the ship is greater than the preset distance threshold, the ship may be in a dangerous state.

[0083] The ship sway data indicates that the attitude angle of the ship is greater than a preset angle threshold. The ship can obtain inertial data as ship sway data through the onboard IMU. The ship sway data can indicate the attitude angle of the ship around at least one rotation axis. If the attitude angle is greater than a preset angle threshold, the ship may be at risk of capsizing. Therefore, when the ship sway data indicates that the attitude angle of the ship is greater than a preset angle threshold, the ship may be in a dangerous state.

[0084] The ship video data indicates that the ship has been invaded by an illegal user. The ship may be equipped with a camera, which may be a visible light camera or an infrared camera. The ship video data may be video data collected by any of the above-mentioned cameras. The person in the video image may be identified by portrait recognition technology to determine whether the person in the video image is a legitimate user. If not, it is determined that the person in the video image is an illegal user. When the ship video data indicates that the ship has been invaded by an illegal user, the ship may be at risk of being stolen and the ship may be in a dangerous state.

[0085] In some embodiments, the second transmission frequency may be positively correlated with the change range of the ship data within a preset time period. Taking the ship water level data as an example, if the growth range of the ship water level data within the preset time period is small, that is, the growth rate is slow, the second transmission frequency may be reduced accordingly. If the growth range of the ship water level data within the preset time period is large, that is, the growth rate is fast, the second transmission frequency may be increased accordingly, so that the user can grasp the change process of the ship data in real time.

[0086] In some embodiments, in addition to sending ship data to the monitoring device when the ship data indicates that the ship is in a dangerous state, the processing unit may also control the monitoring device to issue alarm data to prompt the user that the ship is in a dangerous state.

[0087] In some embodiments, the sensor carried by the ship may include a liquid level sensor. The liquid level sensor may be arranged at a preset height of a side plate connected to the deck of the ship. In this way, the ship data may include water level data collected by the liquid level sensor to characterize the height of water accumulation on the deck of the ship.

[0088] The liquid level sensor may include an infrared liquid level sensor. The infrared liquid level sensor may include an optical transmitter and an optical receiver. The infrared light emitted by the optical transmitter may be received by the optical receiver. When the water level of the accumulated water reaches a preset height set on the side plate of the infrared liquid level sensor, the infrared liquid level sensor will be immersed in the water. Before and after the infrared liquid level sensor is immersed in the water, the optical path of the infrared light will change due to the refraction of the water. In this way, the process of determining the water level of the accumulated water may include the following steps: Figure 5 Steps shown:

[0089] Step 510: If the light intensity of the light received by the light receiver is greater than the preset light intensity threshold, it is determined that the water level of the accumulated water has not reached the preset height;

[0090] Step 520: If the light intensity of the light received by the light receiver is not greater than the light intensity threshold, it is determined that the water level of the accumulated water reaches a preset height.

[0091] Among them, the light received by the above-mentioned light receiver is emitted by the light transmitter. When the water level of the accumulated water does not reach the preset height of the infrared liquid level sensor set on the side panel, the infrared liquid level sensor is above the water surface of the accumulated water, and the infrared light emitted by the light transmitter can be received by the light receiver, so the light intensity received by the light receiver is relatively large. Conversely, when the water level of the accumulated water reaches the preset height, the infrared liquid level sensor will be immersed in water. The refraction of water changes the optical path of the infrared light, resulting in the infrared light being unable to reach the light receiver. In this way, the light receiver cannot receive the infrared light emitted by the light transmitter, resulting in the infrared light intensity detected by the light receiver being relatively weak.

[0092] In addition, the above light intensity threshold can be selected according to actual needs. The appropriate intensity is used as the threshold. For example, if the light transmitter and the light receiver are relatively set at the same height of the two side panels, due to the scattering effect of the atmosphere on the light, the intensity of the infrared light received by the light receiver is negatively correlated with the distance between the light transmitter and the light receiver. That is, the greater the distance between the light transmitter and the light receiver, the weaker the infrared light intensity received by the light receiver. Therefore, the above light intensity threshold can be set according to the distance between the transmitter and the light receiver, for example, the light intensity threshold is negatively correlated with the distance.

[0093] As another example, the light intensity threshold may be determined based on the ambient light intensity of the vessel's environment. Since the ambient light includes infrared light, in order to avoid interference of infrared light in the ambient light on water level detection, the light intensity threshold may be set based on the infrared light intensity of the ambient light to offset the influence of infrared light in the ambient light on detection.

[0094] Of course, in addition to the above-mentioned infrared liquid level sensors, liquid level sensors also include float type liquid level sensors, float type liquid level sensors, static pressure type liquid level sensors and other sensors that measure liquid level by buoyancy or liquid static pressure. Figure 6 As shown, the liquid level sensor may include multiple ( Figure 6 (Three are shown as an example). Multiple liquid level sensors may be disposed at different heights of the side plate 610. Figure 6 As shown, the liquid level sensors 611-613 are respectively arranged at different heights of the side plate 610 from low to high.

[0095] As an example, different setting heights correspond to water level heights of different danger levels. For example, when the water level of the accumulated water reaches the height where the liquid level sensor 611 is located, the danger level at this water level is low. But when the water level of the accumulated water reaches the height where the liquid level sensor 613 is located, the danger level at this water level is high. In response to different danger levels, the monitoring device outputs different levels of alarm information. For example, alarm information with a lower danger level can be output in the form of a pop-up window, and alarm information with a higher danger level can be output in the form of sound or flash.

[0096] As an example, the sending frequencies of water level height data collected by liquid level sensors set at different heights are also different. The sending frequency of water level height data corresponding to each liquid level sensor can be determined according to the current water level height of the accumulated water. For example, a sending strategy for water level height data can be pre-stored, and based on the water level height of the accumulated water, the water level height data of the accumulated water corresponding to multiple liquid level sensors are sent according to the preset sending strategy. Among them, the sending strategy may include: the sending frequency of water level height data corresponding to the first liquid level sensor is greater than the sending frequency of water level height data corresponding to the second liquid level sensor; and / or the sending frequency of water level height data corresponding to the first liquid level sensor is greater than the sending frequency of water level height data corresponding to the third liquid level sensor. Among them, the setting heights of the first liquid level sensor and the second liquid level sensor are higher than the water level height of the accumulated water, and the first liquid level sensor is closer to the water level of the accumulated water than the second liquid level sensor; the setting height of the third sensor is lower than the water level height of the accumulated water; the number of the first liquid level sensor, the second liquid level sensor or the third liquid level sensor can be one or more.

[0097] The sending strategy is applicable to a scenario where the processing unit sends ship data to the monitoring device at a first sending frequency or a second sending frequency.

[0098] For example, the water level data corresponding to the first liquid level sensor may be sent to the monitoring device at a first sending frequency, and the water level data corresponding to the second liquid level sensor and / or the third liquid level sensor may be sent to the monitoring device at a third sending frequency, wherein the third sending frequency is lower than the first sending frequency.

[0099] For another example, when trigger information is monitored, water level height data corresponding to the first liquid level sensor can be sent to the monitoring device at the second sending frequency, and water level height data corresponding to the second liquid level sensor and / or the third liquid level sensor can be sent to the monitoring device at the first sending frequency.

[0100] Of course, in the case of including multiple liquid level sensors, the transmission frequency of the water level data corresponding to each liquid level sensor is not limited to the two cases listed above. Each liquid level sensor can also transmit data at other transmission frequencies, and the data transmission frequencies of the second liquid level sensor and the third liquid level sensor can be the same or different. As long as the data transmission frequencies of the first liquid level sensor, the second liquid level sensor, and the third liquid level sensor meet the size relationship in the transmission strategy.

[0101] by Figure 6 For example, when the water level of the accumulated water is below the height of the liquid level sensor 611, the setting height of the liquid level sensors 611-613 is higher than the water level of the accumulated water, and the liquid level sensor 611 is closer to the water level of the accumulated water than the liquid level sensors 612-613. In this way, it can be determined that the liquid level sensor 611 is the first liquid level sensor; the liquid level sensors 612-613 are the second liquid level sensors. According to the sending strategy, it can be known that the sending frequency of the water level height data corresponding to the liquid level sensor 611 is greater than the sending frequency of the water level height data corresponding to the liquid level sensors 612-613.

[0102] When the water level of the accumulated water reaches above the height of the liquid level sensor 611, the setting height of the liquid level sensor 611 is lower than the water level of the accumulated water, the setting height of the liquid level sensors 612-613 is higher than the water level of the accumulated water, and the liquid level sensor 612 is closer to the water level of the accumulated water than the liquid level sensor 613. In this way, it can be determined that the liquid level sensor 611 is the third sensor; the liquid level sensor 612 is the first liquid level sensor; and the liquid level sensor 613 is the second liquid level sensor. According to the sending strategy, it can be known that the sending frequency of the water level height data corresponding to the liquid level sensor 612 is greater than the sending frequency of the water level height data corresponding to the liquid level sensor 611 and the liquid level sensor 613. Among them, the sending frequency of the water level height data corresponding to the liquid level sensor 611 and the liquid level sensor 613 may be the same or different.

[0103] When the water level of the accumulated water reaches above the height of the liquid level sensor 612, the setting height of the liquid level sensors 611-612 is lower than the water level of the accumulated water, and the setting height of the liquid level sensor 613 is higher than the water level of the accumulated water. In this way, it can be determined that the liquid level sensors 611-612 are the third sensors; and the liquid level sensor 613 is the first liquid level sensor. According to the sending strategy, it can be known that the sending frequency of the water level data corresponding to the liquid level sensor 613 is greater than the sending frequency of the water level data corresponding to the liquid level sensors 611-612. Among them, the sending frequencies of the water level data corresponding to the liquid level sensors 611 and 612 may be the same or different.

[0104] In this embodiment, in the case where the ship includes multiple liquid level sensors, the sending frequency of the water level data corresponding to each liquid level sensor is determined according to the relationship between the water level of the accumulated water and the setting height of each liquid level sensor. For the liquid level sensors that are above the accumulated water level and closer to the accumulated water level, the data sending frequency is relatively high, so that the user can pay attention to the changes in the accumulated water level in time. For the liquid level sensors that are already below the accumulated water level, and above the accumulated water level but farther away from the accumulated water level, their water level data have less reference value for the changes in the accumulated water level, so the data sending frequency is relatively low, thereby saving the cost of data transmission and extending the ship's cruising time.

[0105] In addition, the present application also provides a data processing method, which is applied to Figure 1A-Figure 1C The monitoring device 130 shown. Figure 1A-Figure 1C As shown, the monitoring device 130 is connected to the processing unit 120 for communication, and the processing unit 120 is also connected to the sensor 111 carried by the ship 110 for communication. The above method includes the following steps: Figure 7 Steps shown:

[0106] Step 710: receiving ship data collected by the sensor and sent by the processing unit at a first transmission frequency;

[0107] Among them, the ship data is used for users to view through the monitoring device.

[0108] Step 720: If it is detected that the user is viewing the ship data, a trigger message is sent to the processing unit;

[0109] The trigger information is used to trigger the change of the data transmission frequency;

[0110] Step 730: The receiving processing unit sends the ship data at the second sending frequency when the trigger information is detected;

[0111] The first sending frequency is less than the second sending frequency; the trigger information is sent by the monitoring device and / or is generated when the ship data indicates that the ship is in a dangerous state.

[0113] In addition, the present application also provides a data processing method, which is applied to a ship monitoring system.

The processing unit 120 is also connected in communication with a sensor carried by the ship. The above method includes the following steps: Figure 8 Steps shown:

[0114] Step 810: The processing unit 120 sends the ship data collected by the sensor to the monitoring device 130 at a first transmission frequency, and monitors the trigger information at the same time;

[0115] Among them, the trigger information is used to trigger the change of data sending frequency

[0116] Step 821: The monitoring device 130 detects that a user is viewing ship data;

[0117] Step 822: Send trigger information to the processing unit 120;

[0118] Step 831: The processing unit 120 determines that the ship data indicates that the ship is in a dangerous state

[0119] Step 832: The processing unit 120 generates trigger information;

[0120] Step 840: When the processing unit 120 detects the trigger information, it sends the ship data to the monitoring device 130 at the second sending frequency.
