[0040] The typical embodiments embodying the features and advantages of the present application will now be described in detail. It should be appreciated that the present application can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and fully convey the scope of the application to those skilled in the art.

[0041] In order to further illustrate the principles and features of the present application, preferred embodiments of the present application will now be described in detail in conjunction with the accompanying drawings.

[0042] The present application provides a fuel storage mechanism, which is suitable for a ship powered by LNG, LPG, hydrogen fuel or other fuel.

[0043] The ship includes a ship body and a fuel storage mechanism detachably connected to the ship body.

[0044] The fuel storage mechanism includes a fuel detection device and a fuel storage mechanism, and the fuel storage mechanism is used to carry fuel to provide power for the ship body, and the fuel detection device is used to detect the state parameter of the fuel in the fuel storage mechanism. The detachable connection of the fuel storage mechanism and the ship body enables the ship body to achieve the purpose of loading by replacing the fuel storage mechanism. The fuel is LNG, LPG or hydrogen.

[0045] When the ship needs to be loaded with fuel, it sails to a filling station and replaces the fuel storage mechanism in the filling station. That is, the fuel storage mechanism on the ship body is detached, and the fuel storage mechanism filled with fuel or meeting the fuel requirement of the ship body in the filling station is installed on the ship body.

[0046] The filling station has fuel storage mechanisms carrying fuel for replacement. The filling station can be a gas station, or any wharf with fuel storage mechanisms. The fuel storage mechanisms at the wharf can be filled on site by tank trucks, or transported to a gas station for filling.

[0047] The fuel storage mechanism replaced by the ship body can be filled and loaded in the gas station, or filled and loaded in the wharf, and then the next ship body can be loaded by replacing the fuel storage mechanism.

[0048] The fuel storage mechanism will be described in detail below.

[0049] As shown in Figure 1 , the fuel storage mechanism includes a fuel detection device 1 and a fuel storage tank for carrying fuel, and the fuel detection device 1 is used to detect the state parameters of the fuel in the fuel storage tank. In this embodiment, the fuel detection device 1 is a remote control box, which includes a fuel detection module 11, a positioning module 12, a detection module 13 and a communication module 14, and the fuel storage tank is a storage tank.

[0050] In this embodiment, the fuel detection module 11 includes sensors for detecting the pressure, temperature and liquid level of the storage tank, so as to detect the state of the fuel in the storage tank.

[0051] The positioning module 12 is a BD / GPS module with 33 tracking channels, 99 acquisition channels, horizontal positioning accuracy <2.5m CEP, speed accuracy <0.1m / s, and acceleration accuracy <0.1m / s 2 . When the remote control box is in working condition, the position information of the storage tank can be generated in real time, and the position information is transmitted to the fuel detection module 11.

[0052] The detection module 13 is used to determine whether the remote control box is connected to the power supply according to the charging signal. When the remote control box is connected to the power supply, the fuel storage mechanism is usually installed on the LNG power ship, and the power supply on the ship is connected to obtain electric energy. Then the detection module 13 controls the fuel detection module 11 to enter the real-time detection mode. When the remote control box is not connected to the power supply, the fuel storage mechanism is usually located in the yard, wharf or vehicle transportation, and cannot obtain electric energy from the outside. Then the detection module 13 controls the fuel detection module 11 to enter the timing detection mode to reduce the energy consumption of the remote control box itself.

[0053] The communication module 14 can use a 4G communication module, LTE Cat1 wireless communication, full network, etc.; the maximum downlink rate is 10Mbs and the uplink rate is 5Mbps. When the remote control box is working, the position information, liquid level, temperature, pressure, gas leakage value and use state of the storage tank are preprocessed by information screening, removing outliers and encryption, and then sent to the cloud server through the 4G mobile wireless network to realize real-time sharing and backup of information; at the same time, the instructions issued by the cloud server are responded, such as adjusting the detection mode and feeding back the information obtained by detecting the storage tank.

[0054] In the embodiment, when the fuel storage mechanism is not installed on the ship, i.e. is located in the storage yard, the wharf or is in the vehicle transportation process, since the fuel detection device 1 cannot obtain external power due to no power supply connection, and the corresponding risk coefficient of the storage yard, the wharf or the vehicle transportation process is relatively low, it is not necessary to detect the fuel storage tank in real time, but to realize detection for a preset number of times at a preset time point, such as 4 times a day, and the detection time points are 8 o'clock, 14 o'clock, 20 o'clock and 2 o'clock the next day. Since the risk coefficients corresponding to the storage yard, the wharf or the vehicle transportation process also have differences, the detection time points and the detection times can be further distinguished. For example, the risk coefficient of the fuel storage mechanism located in the storage yard is lower than that of the vehicle transportation process, and the former corresponds to 4 times a day, and the detection time points are 8 o'clock, 14 o'clock, 20 o'clock and 2 o'clock the next day, and the latter corresponds to 6 times a day, and the detection time points are 4 o'clock, 8 o'clock, 12 o'clock, 16 o'clock, 20 o'clock and 0 o'clock the next day. The information obtained by detection is uploaded to the cloud server in time through the communication module 14, and the fuel detection device 1 is in a dormant state in the time period other than the detection time point, so as to achieve the purpose of energy saving.

[0055] When the fuel storage mechanism is installed on the ship, the fuel detection device 1 is connected with the power supply system of the ship to obtain power, and since the risk coefficient corresponding to the fuel storage mechanism is high when the ship sails on the sea, it is necessary to detect the fuel storage tank in real time and upload the related information, so as to ensure the safety of the fuel storage mechanism and the ship.

[0056] Further, as shown in Figure 1 The ship is provided with a security control system, and the fuel detection device 1 is connected with the security control system. The fuel detection device 1 further comprises a signal transmission module 15 connected with the fuel detection module 11, the positioning module 12 and the security control system respectively, and the state parameters and the real-time position are transmitted to the security control system, so that the security control system estimates the remaining fuel navigation range corresponding to the fuel storage tank according to the state parameters, and determines a target filling station according to the remaining fuel navigation range and the real-time position. The target filling station is used to store a plurality of fuel storage mechanisms.

[0057] Specifically, as shown in Figure 2As shown, in the embodiment, the fuel detection device 1 is a remote control box, the security control system is a security system control cabinet, and the remote control box and the security system control cabinet are connected through a CAN bus. The signal transmission module 15 of the fuel detection device 1 includes a CAN2.0A interface, which satisfies a maximum rate of 1Mbit / S and is connected with a security control system CAN bus interface of the ship to transmit relevant data. In actual application, fuel in the fuel storage is used to provide power for the ship, and the ship is provided with a security control system to monitor real-time states of various devices on the ship, so that when the fuel detection device 1 detects relevant state parameters of the fuel storage, the state parameters are transmitted to the security control system for safety evaluation or execution of corresponding safety measures. The state parameters include a liquid level of fuel in the fuel storage and a volume of the fuel storage, and the security control system can determine a remaining amount of fuel in the fuel storage according to the liquid level and the volume, and then determine an engine fuel consumption rate, usually an engine gas rate, by monitoring an operating state of an engine of the ship, and determine a remaining navigation distance of the fuel in the fuel storage that can support the ship to travel according to the remaining amount of fuel and the engine gas rate. When the remaining navigation distance does not reach a preset navigation distance, i.e., a safety range, the security control system searches for a nearest refueling station according to a real-time position of the fuel storage generated by the positioning module 12 and goes to the refueling station to replace the fuel storage mechanism to ensure that the ship has sufficient fuel to travel to the destination.

[0058] Further, as shown in the embodiment, the fuel detection device 1 further includes a state detection module 16 connected with the signal transmission module 15. The state detection module 16 is used to detect a flammable gas concentration around the fuel storage and a pipeline connection state corresponding to the fuel storage, and transmit the detected flammable gas concentration and pipeline connection state to the security control system through the signal transmission module 15. Figure 1

[0059] Specifically, since the fuel stored in the fuel storage mechanism is liquefied natural gas, and the fuel storage mechanism is often installed and dismounted on the ship, in order to prevent the liquefied natural gas stored in the fuel storage mechanism from leaking, the state detection module 16 includes sensors respectively used to detect the flammable gas concentration around the fuel storage and detect the pipeline connection state connected with the fuel storage, so that when the fuel storage mechanism is installed on the ship, natural gas leakage caused by the fuel storage itself or a pipeline valve not being closed in time is avoided.

[0060] Further, as shown in the embodiment, the fuel detection device 1 further includes a state detection module 16 connected with the signal transmission module 15. The state detection module 16 is used to detect a flammable gas concentration around the fuel storage and a pipeline connection state corresponding to the fuel storage, and transmit the detected flammable gas concentration and pipeline connection state to the security control system through the signal transmission module 15. Figure 1 ​As shown, the fuel detection device 1 is provided with at least one of an AD sampling circuit or a digital quantity information transmission interface, and the fuel detection module 11 is connected to the fuel storage device through one or more of the AD sampling circuit or the digital quantity information transmission interface to detect the state parameters of the fuel storage device.

[0061] Specifically, since different manufacturers produce fuel storage devices, i.e., tanks, and different production specifications / standards are implemented, the transmission mode of the connected sensor is set to be an AD sampling circuit or a digital quantity information transmission interface, wherein the AD sampling circuit is used to transmit analog signals, and the digital quantity information transmission interface, usually an RS485 interface, is directly used to transmit digital quantity information. Therefore, the fuel detection device 1 is preferably provided with both of the above transmission modes to adapt to tanks produced by different manufacturers, thereby improving the practicability of the fuel detection device 1.

[0062] Further, as shown in Figure 1 The fuel detection device 1 further includes a signal conversion module 17 connected to the fuel detection module 11, which is used to convert the state parameters of the AD sampling circuit from analog signals to digital quantity information.

[0063] Specifically, the signal conversion module 17 is a 12-bit AD converter. When the fuel detection device 1 is connected to the pressure, temperature, liquid level, and combustible gas sensor of the tank through the AD sampling circuit and 4-20 mA signal interface to collect the state parameters of the fuel storage device, such as the liquid level, pressure, and temperature, the analog signals are directly collected and need to be converted into digital quantity information by the 12-bit AD converter.

[0064] Further, as shown in Figure 1 The fuel detection device 1 further includes an energy storage module 18 connected to the fuel detection module 11, the positioning module 12, and the communication module 14 and providing corresponding electrical energy.

[0065] Specifically, the energy storage module 18 includes a backup power supply or a solar panel, etc. so that when the fuel storage mechanism is not installed on a ship and cannot obtain electrical energy from the outside, the backup power supply or solar energy can ensure that the fuel detection module 11, the positioning module 12, and the communication module 14 can normally operate, avoiding the situation that the fuel storage mechanism is out of contact.

[0066] Figure 3A preferred embodiment of the present application is shown, the fuel detection device 1 adopts a low-energy-consumption MCU, which obtains power based on a power supply DC 9-36V; generates real-time position through BD / GPS dual-mode positioning; uploads information to a cloud server through a 4G communication module; collects analog signals of state parameters such as pressure, temperature and liquid level of the fuel storage through an 8-way AD interface; detects whether the pipeline connection is in place through a 4-way digital input interface; collects digital information of state parameters of the fuel storage through an RS485 communication interface; and transmits data to a security control system through a CAN2.0 interface.

[0067] The fuel detection device 1 in the embodiment includes a fuel storage device for storing fuel and a fuel detection device 1 installed on the fuel storage device. The fuel storage device is usually placed in a filling station and can provide power for an LNG-powered ship or be transported as cargo by an LNG-powered ship. When the fuel storage device is not connected to a power supply, the fuel detection device 1 performs periodic detection on the fuel storage device, and the detection frequency is determined according to the location of the fuel storage device, thereby achieving energy saving. When the fuel storage device is connected to the power supply of the LNG-powered ship, the fuel detection device 1 performs real-time detection on the fuel storage device to ensure the safety of the fuel storage device and the LNG-powered ship. In this way, the fuel tank storing LNG is monitored by changing the detection mode and the detection frequency of the fuel detection device 1, ensuring the safety of the fuel tank and the ship, and further improving the practicality of the LNG-powered ship.

[0068] As shown in Figure 4 The present application also provides a fuel detection method for a fuel storage device, which specifically includes the following steps:

[0069] Step S100, detecting the power connection state of the fuel detection device 1, the power connection state including a connected power supply and an unconnected power supply;

[0070] Step S200, determining the detection mode corresponding to the fuel detection device 1 according to the power connection state, and detecting the state parameters of the fuel storage device according to the detection mode, the state parameters of the fuel storage device being parameters reflecting the state of the fuel in the fuel storage device, and the detection mode including real-time detection and periodic detection;

[0071] Step S300, transmitting the state parameters of the fuel storage device to a cloud server and / or a security control system.

[0072] Specifically, when the fuel storage mechanism has been installed on the LNG powered ship, at this time the fuel detection device 1 is connected to the power supply, and the power supply on the ship is turned on to obtain electric energy, the detection module 13 controls the fuel detection module 11 to enter the real-time detection mode, and the state parameters obtained by detecting the fuel storage are uploaded to the cloud server for sharing and backup, and are also transmitted to the security control system of the ship for safety evaluation; when the fuel storage mechanism is located in the yard, the wharf or is in the process of vehicle transportation, at this time the fuel detection device 1 is not connected to the power supply, the detection module 13 controls the fuel detection module 11 to enter the timing detection mode, and the state parameters obtained by detecting the fuel storage are uploaded to the cloud server for sharing and backup, and the fuel detection device 1 enters the sleep state in the event segment outside the detection time point, so as to reduce the energy consumption of itself.

[0073] Further, as shown in Figure 5 The state parameters include the liquid level parameter and the volume parameter, and after the detection of the state parameters of the fuel storage according to the detection mode in step S200, the fuel detection method further comprises:

[0074] Step S201, determining the remaining fuel navigation distance corresponding to the fuel storage mechanism according to the liquid level parameter and the volume parameter;

[0075] Step S202, comparing the remaining fuel navigation distance with a preset navigation distance;

[0076] Step S203, if the remaining fuel navigation distance is equal to or less than the preset navigation distance, determining the nearest refueling station as the target refueling station according to the real-time position of the fuel storage mechanism, and replacing the fuel storage mechanism at the target refueling station.

[0077] Specifically, the security control system determines the remaining amount of fuel in the fuel storage according to the liquid level and the volume of the fuel storage sent by the fuel detection device 1, and then determines the engine fuel consumption rate, usually the engine gas rate, by monitoring the running state of the engine of the ship, and determines the remaining navigation distance that the fuel in the fuel storage can support the ship to travel according to the above-mentioned fuel remaining amount and engine gas rate, when the remaining navigation distance does not reach the preset navigation distance, i.e. the safety range, the security control system searches for the nearest refueling station around according to the real-time position of the fuel storage generated by the positioning module 12, and goes to the refueling station to replace the fuel storage mechanism, so as to ensure that the ship has sufficient fuel to travel to the destination.

[0078] Further, as shown in Figure 6As shown, the state parameters of the fuel storage also include a pipeline connection state, after detecting the state parameters of the fuel storage according to the detection mode in step S200, the fuel detection method further comprises:

[0079] Step S204, comparing the state parameters with preset standard values;

[0080] Step S205, if it is determined that the state parameters are in an abnormal range through the comparison, performing corresponding alarm operations.

[0081] Specifically, the above-mentioned state parameters include the liquid level, temperature, pressure, pipeline connection state, and combustible gas concentration of the fuel storage. Since the fuel stored in the fuel storage is natural gas, which is a flammable and explosive substance, after detecting the fuel storage, the fuel detection device 1 compares each state parameter obtained through the detection with the corresponding preset standard value, such as whether the temperature in the fuel storage is too high, whether the pressure is too high, whether the pipeline connection is in place, whether the valve of the pipeline is in the corresponding open / closed state, and whether the combustible gas concentration is too high, which means natural gas leakage. When the above-mentioned state parameters are in an abnormal range, the fuel detection device 1 performs corresponding alarm operations, such as issuing an alarm, sending warning information to the security control system of the ship, etc.

[0082] Further, as shown, Figure 7 When the power connection state is not connected to the power supply, and the detection mode is a timed detection, the step S200 of detecting the state parameters of the fuel storage according to the detection mode comprises:

[0083] Step S206, detecting the real-time position of the fuel storage and determining the number of detections corresponding to the timed detection according to the real-time position;

[0084] Step S207, performing the timed detection of the state parameters of the fuel storage according to the number of detections.

[0085] When the fuel storage mechanism is not installed on the ship, i.e. in the yard, at the wharf, or in the process of vehicle transportation, since the fuel detection device 1 cannot obtain external power due to the unconnected power supply, and the corresponding risk factor of the yard, wharf, or vehicle transportation is relatively low, it is not necessary to perform real-time detection of the fuel storage, but only a preset number of detections at preset time points, such as 4 detections per day at 8 o'clock, 14 o'clock, 20 o'clock, and 2 o'clock the next day. Since the corresponding risk factors of the yard, wharf, or vehicle transportation also differ, the detection time points and the number of detections can be further distinguished.

[0086] Specifically, the fuel detection device 1 generates real-time position according to the positioning module 12, such as located in the yard, and the risk factor of the fuel storage mechanism located in the yard is lower than that of the vehicle in transit, so it is detected 4 times a day, and the detection time points are 8 o'clock, 14 o'clock, 20 o'clock and 2 o'clock the next day; When the real-time position is in transit, such as some highways, etc., it is detected 6 times a day, and the detection time points are 4 o'clock, 8 o'clock, 12 o'clock, 16 o'clock, 20 o'clock and 0 o'clock the next day; And the information detected is uploaded to the cloud server in time through the communication module 14, and the fuel detection device 1 is in a dormant state during the time period other than the detection time point, so as to achieve the purpose of energy saving.

[0087] The fuel detection method for the fuel storage mechanism in the embodiment can execute different detection modes according to whether the fuel storage mechanism is installed on the ship, and further calculate the sailing distance supported by the remaining fuel under the condition of power on, and determine whether to go to the nearest refueling station to supplement fuel and how to go, and further distinguish the detection times according to different scenes under the condition of power off, so as to improve the energy saving effect.

[0088] Although the present application has been described with reference to several exemplary embodiments, it is understood that the terms used are illustrative and not restrictive terms. Since the present application can be embodied in various forms without departing from the spirit or essential characteristics thereof, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but are to be broadly interpreted within the spirit and scope of the appended claims, and all changes and modifications that fall within the scope of the claims or their equivalents should be covered by the appended claims.
