In the related art, in order to reduce the risk of sinking the ship, a liquid level sensor can be arranged at the bilge of the ship so as to monitor the water accumulation condition of the bilge, and a drainage pump is controlled to drain the accumulated water in time when the water accumulation condition is serious. A liquid level sensor may be provided outside the side wall of the hull of the vessel to monitor the height of the water around the vessel (which may also be understood as the height of the vessel submerged under the water), and an alarm may be given when the height is closer to the high point of the side wall.

However, even if the liquid level sensor is provided at the bilge of the ship and the liquid level sensor is provided outside the side wall of the hull of the ship at the same time, the ship risks sinking. It will be appreciated that neither the owner nor the crew will generally be on the vessel when the vessel is in the berthed condition, i.e. no one is on the vessel. At this time, if the wind and waves in the berthing area of the ship are large and the wave height is higher than the height of the side wall in the hull plate of the ship, the seawater is likely to gush into the interior of the ship, so that the water accumulation occurs at the deck of the ship. When the accumulated water at the deck of the ship is less, the accumulated water possibly cannot cause great influence on the ship, and a shipowner and a crew only need to discharge the accumulated water after finding the accumulated water. However, since no one is on the ship, the accumulated water on the deck of the ship may not be discharged in time, so that the water level of the accumulated water is higher and higher, and the weight of the accumulated water is also higher and higher. Therefore, as time goes on, before the shipowner and the crew find that the accumulated water in the deck of the ship reaches a certain degree, the weight of the accumulated water may exceed the upper limit of the weight that the ship can bear, so that the ship sinks, the ship is damaged or even lost due to the pressure of seawater, great influence is caused on the ship, and economic loss is brought to the shipowner.

To this, this application provides a monitoring system of boats and ships deck department ponding for solve above-mentioned problem.

Next, examples of the present application will be described in detail.

As shown in fig. 1, the present application provides a system for monitoring water accumulation at the deck of a vessel that may include a level sensor 110, an alarm device 120, and a processor 130.

Wherein, the liquid level sensor 110 is used for monitoring the height of the water level of the accumulated water;

the alarm device 120 is used for alarming;

the processor 130 is connected to the liquid level sensor 110 and the alarm device 120 respectively; for receiving the sensing information outputted by the liquid level sensor 110, determining whether the water level height reaches a preset height according to the sensing information, and controlling the alarm device 120 to alarm if the water level height reaches the preset height.

Firstly, the real-time monitoring of the water level height of the accumulated water on the ship deck can be realized by receiving the collected sensing information of the liquid level sensor 110 which is arranged on the ship and used for detecting the water level height of the accumulated water on the deck. The liquid level sensor 110 is a sensor for measuring the liquid level position, and can convert the liquid level into an electrical signal for output. The sensing information is an electric signal generated after the liquid level sensor 110 collects the liquid level position, and after the liquid level sensor 110 sends the sensing information to other equipment, the other equipment can know the height of the corresponding liquid according to the sensing information, so that various operations related to the liquid height are executed. In this application, what level sensor 110 detected is the water level height of boats and ships deck department ponding, and the information that the response information is then that level sensor 110 generates according to its information of gathering can the signal of telecommunication, and this response information can reflect the water level height of boats and ships deck department ponding to a certain extent.

In some embodiments, the level sensor 110 may detect the real-time height of the water accumulation and generate different sensing information based on the current height of the water accumulation. For example, the liquid level sensor 110 may be an ultrasonic liquid level sensor 110, the ultrasonic liquid level sensor 110 is disposed at a certain height on a ship deck, the ultrasonic liquid level sensor 110 may transmit an ultrasonic wave downwards and receive an echo reflected after the ultrasonic wave contacts a surface of the ponding liquid, so as to calculate a distance between the ultrasonic liquid level sensor 110 and the surface of the ponding liquid according to a time difference between the transmission of the ultrasonic wave and the reception of the echo, thereby calculating a real-time height of the ponding. In some embodiments, the level sensor 110 capable of detecting the real-time height of the accumulated water may be other types of level sensors 110, which is not limited in this application.

In some embodiments, the level sensor 110 may only detect whether the accumulated water reaches a predetermined height, and generate different sensing information according to whether the accumulated water reaches the predetermined height and does not reach the predetermined height. For example, the liquid level sensor 110 may be a capacitive liquid level sensor 110, the capacitive liquid level sensor 110 is disposed at a specified height on a deck of the ship, when the height of the accumulated water reaches or exceeds the specified height, the capacitive liquid level sensor 110 makes contact with the accumulated water, and the capacitive liquid level sensor 110 may generate sensing information indicating that the height of the accumulated water reaches the specified height; if the height of the accumulated water is below the specified height, and the capacitive liquid level sensor 110 is not in contact with any liquid, the capacitive liquid level sensor 110 may generate sensing information indicating that the height of the accumulated water does not reach the specified height. In some embodiments, the level sensor 110 for detecting whether the accumulated water reaches a specified height may be other types of sensors, which are not limited in this application.

In some embodiments, the level sensor 110 may be provided on a side plate connected to the deck, wherein the side plate extends from the connection to the deck in a direction away from the bottom plate of the vessel. For example, the level sensor 110 may be a contact level sensor 110, and when the accumulated water reaches a certain height, the accumulated water may contact the level sensor 110 on the side plate, thereby triggering the level sensor 110 to generate different sensing information.

In some embodiments, the level sensor 110 may also be located on the deck, i.e., at the bottom of the standing water. For example, the liquid level sensor 110 may be a static pressure type liquid level sensor 110, and when the height of the accumulated water changes, the water pressure applied to the liquid level sensor 110 at the bottom of the accumulated water will also change, thereby triggering the liquid level sensor 110 to generate different sensing information according to different pressures.

In some embodiments, the level sensor 110 may also be suspended above the deck. For example, the liquid level sensor 110 may be a floating ball type liquid level sensor 110, when the height of the accumulated water changes, a floating ball of the liquid level sensor 110 may follow the rising of the accumulated water, and the change in the height of the floating ball may trigger the liquid level sensor 110 to generate different sensing information.

In the present application, the position at which the level sensor 110 is disposed should be determined according to the type of the level sensor 110. In some embodiments, the level sensor 110 may also be disposed elsewhere on the ship, as long as the level sensor 110 can be used to detect the water level of the accumulated water at the deck, which is not limited in this application.

In some embodiments, the number of level sensors 110 provided on the deck of the vessel may be only one. Through setting up a level sensor 110 on boats and ships, can realize the detection to the water level height of ponding.

In some embodiments, the number of level sensors 110 provided on the deck of the vessel may also be plural. Through setting up a plurality of level sensor 110 on boats and ships, can improve detection precision, detection width and the detection depth to the water level height of ponding. For example, a plurality of liquid level sensors 110 are respectively arranged for detecting the water level of the accumulated water for the same designated height on the deck of the ship, and when any one of the liquid level sensors 110 fails to cause an error in the detection result, the water level of the accumulated water can be detected by the other liquid level sensors 110. In some embodiments, there may be situations where the height of the accumulated water is different at different positions in the ship, and therefore, the level sensors 110 may be respectively disposed at different positions to detect the height of the accumulated water at different positions. In some embodiments, the level sensors 110 may also be provided at multiple levels in the same installation in the vessel, so that different treatments may be performed at different heights of the accumulated water. In some embodiments, when a plurality of level sensors 110 are provided on the ship, the level sensors 110 may be the same type of level sensor 110, or may be different types of level sensors 110, which is not limited in this application.

In some embodiments, the liquid level sensor 110 used in the present application may be at least one of a float-type liquid level sensor 110, a static pressure-type liquid level sensor 110, and a light level sensor 110, and may also be another type of liquid level sensor 110, as long as it can detect the accumulated water at the deck of the ship, which is not limited in the present application.

In some embodiments, when the level sensor 110 is a light level sensor 110, the light used by the light level sensor 110 may be light that is attenuated more in the liquid. For example, in some embodiments, the light level sensor 110 may be an infrared light level sensor 110. In some embodiments, the infrared light sensor may include an infrared light transmitter and an infrared light receiver, both disposed at the same predetermined designated height of the vessel, the infrared light transmitter may transmit infrared light, and the infrared light receiver may be configured to receive infrared light transmitted by the infrared light transmitter. When no water enters or the water inflow is less at the deck of the ship, the water level of the accumulated water on the deck is lower, the infrared light emitted by the infrared light emitter is transmitted through the air, and the amount of the infrared light emitted by the infrared light emitter and received by the infrared light receiver is more. And when the deck department of boats and ships intake and the inflow is more, the water level height of deck ponding is higher, infrared ray transmitter and infrared ray receiver will be by the submergence in ponding, the infrared light that infrared ray transmitter transmitted will propagate through ponding, and because infrared light attenuation ratio is great when the aquatic is propagated, consequently, infrared ray receiver will unable to receive the infrared light that infrared ray transmitter transmitted, perhaps infrared ray receiver can only receive a small amount of infrared light. Therefore, the infrared light level sensor 110 can generate different sensing information according to the amount of light emitted by the infrared light emitter received by the infrared light receiver. In some embodiments, the sensing information output by the infrared light level sensor 110 may be light intensity information of light received by the infrared light receiver.

In some embodiments, the infrared light transmitter and the infrared light receiver in the infrared light level sensor 110 may be disposed on two opposing side panels of the deck, such that the infrared light receiver can directly receive the linear light emitted by the infrared light transmitter. In some embodiments, it should also be ensured that there are no other obstructions between the infrared light emitters and the infrared light receivers on the two side panels to ensure that no other obstructions will interfere with the sensing of the infrared light level sensor 110.

In some embodiments, the infrared light emitter and the infrared light receiver of the infrared light level sensor 110 may be disposed on the same side plate, and the infrared light receiver may be capable of receiving a reflected light emitted by the infrared light emitter and reflected by another side plate opposite to the side plate where the infrared light emitter and the infrared light receiver are disposed. Different from the infrared light level sensor 110 which is respectively arranged on the side plates at two sides of the infrared light transmitter and the infrared light receiver, in some embodiments, other shelters can exist between the side plate where the infrared light transmitter and the infrared light receiver are located and the other opposite side plate, as long as when accumulated water reaches a specified height, accumulated water can pass through the shelters and the infrared light level sensor 110, and the reflected light received by the infrared light receiver can be influenced by the propagation in the accumulated water. It should be noted that the other shields should be fixed and cannot be moved easily, so as to avoid that the propagation path of the reflected light received by the infrared light receiver changes after the shield is moved, and further, the amount of light received by the infrared light receiver fluctuates greatly, which affects the detection result.

After the sensing information of the liquid level sensor 110 is obtained, whether the water level of the current accumulated water reaches the preset height or not can be judged according to the sensing information, so that whether the risk of sinking the ship exists or not and whether the accumulated water needs to be processed or not can be judged. Wherein, predetermine highly being used for instructing the water level height that needs to pay attention to, after the water level height of ponding reaches predetermineeing highly, it is very likely to lead to ponding weight to exceed the degree that boats and ships can bear, has the risk of sinking the ship promptly to mean to continue to intake on the boats and ships, needs in time to handle ponding.

In some embodiments, the preset height may be determined according to a risk water level height on the deck of the vessel, wherein the vessel may be at risk of sinking when the water level height of the standing water on the deck reaches the risk water level height. The risk water level height of the ship can be obtained through experiments or data calculation.

In some embodiments, the preset height may be a height not higher than the above-mentioned risk water level height, so that the accumulated water can be treated in time before the risk of sinking the ship occurs.

In some embodiments, a certain buffer height can be reserved between the preset height and the risk water level height, so that before the risk of sinking the ship occurs, a certain buffer time is provided, and a shipowner or a crew can catch up from a remote place or arrange any personnel to treat the accumulated water.

In some embodiments, a plurality of preset heights can be further arranged on the ship, and different preset heights correspond to different alarm levels, so that different degrees of alarm can be performed respectively according to different degrees of water inflow, a shipowner or a crew can more accurately grasp the ponding condition of the ship, and whether corresponding processing is needed or not is determined. For example, in some embodiments, 10cm may be set to a height corresponding to a first level of alert level, indicating "deck water in, need of attention"; setting 30cm as the height corresponding to the second-level alarm level to indicate that 'more water is accumulated and needs to be treated'; setting 50cm as the height corresponding to the third-level alarm level indicates that 'risk exists and processing is needed urgently'.

In some embodiments, when a plurality of preset heights are set on the ship, a plurality of liquid level sensors 110 may be set on the ship, wherein each preset height corresponds to one liquid level sensor 110, respectively, for detecting whether the water level height of the accumulated water has reached the height corresponding to the liquid level sensor 110. In some embodiments, for each preset height, a plurality of level sensors 110 may be disposed to perform multi-directional detection, which is not limited in the present application.

In some embodiments, when the liquid level sensor 110 is an infrared liquid level sensor 110 as described in the previous embodiments, and the infrared liquid level sensor 110 includes an infrared transmitter and an infrared receiver, and the sensing information of the liquid level sensor 110 is the light intensity information of the light received by the infrared receiver, it is possible to determine whether the water level of the accumulated water reaches the preset height by determining whether the light intensity information of the light received by the infrared receiver is less than a preset light intensity threshold. When the light intensity information of the light received by the infrared light receiver is greater than or equal to a preset light intensity threshold value, it can be determined that the water accumulation amount higher than the preset height does not exist on the transmission deck; when the light intensity information of the light received by the infrared light receiver is smaller than a preset light intensity threshold value, the water level height of the accumulated water can be determined to reach or be higher than a preset height.

In some embodiments, because the size diverse of boats and ships, infrared light transmitter and infrared light receiver are also different in the mode of setting on boats and ships, therefore, the distance that sets up between infrared light transmitter and the infrared light receiver on boats and ships is also different, and the light intensity information of the light that infrared light transmitter received is relevant with the propagation distance of light, therefore, be used for judging whether ponding water level reaches the propagation distance of the light that infrared light receiver received and sets up according to the predetermined light intensity threshold value of presetting the height, so that it is more accurate to judge according to infrared light level sensor 110's response information whether ponding water level reaches the judged result of presetting the height. In some embodiments, when the infrared light transmitter and the infrared light receiver are respectively disposed on the side plates on both sides of the ship, the preset light intensity threshold may be determined according to a distance between the infrared light transmitter and the infrared light receiver. In some embodiments, when the infrared light transmitter and the infrared light receiver are both disposed on the same side plate of the ship, the predetermined light intensity threshold may be determined according to the distance between the infrared light transmitter and the infrared light receiver and the other side plate for reflecting light or the middle shelter.

Since the ambient light also has a small amount of infrared light, and the infrared light may be received by the infrared light receiver, the ambient light intensity of the current environment also affects the light intensity information of the light received by the infrared light receiver. In some embodiments, the preset light intensity threshold may also be determined according to the ambient light intensity of the current environment. In some embodiments, the basic preset light intensity threshold may be determined according to a propagation distance from the time of transmitting the light emitted by the infrared light transmitter to the time of receiving the light by the infrared light receiver, and then the basic preset light intensity threshold may be dynamically adjusted by detecting the ambient light intensity of the current environment, so that the preset light intensity threshold has higher accuracy. In some embodiments, the ambient light may be detected accurately by the ambient light sensor, or may be determined roughly by combining the position of the ship, the current time, the weather, and the like, which is not limited in this application.

And after the water level of the current accumulated water reaches the preset height, alarming can be performed by controlling the alarming device 120, so that a shipman or a crew can process the accumulated water condition of the ship in time by providing alarming information.

In some embodiments, the warning device 120 may be a fixed device installed on the ship, or may be a fixed device installed at a specific location on the shore, or may be a mobile device that can be carried around. For example, in some embodiments, the alerting device 120 may be a smartphone of a shipowner or crew.

In some embodiments, the number of the above-mentioned alarm devices 120 may be one, or may be multiple, so as to implement multiple personnel and multiple degrees of alarm.

In some embodiments, when the warning device 120 is controlled to give a warning, the warning device 120 may be controlled to give a warning sound, and a shipowner or a crew, etc. is reminded to pay attention to the water accumulation condition on the deck of the ship in time through a sudden or loud warning sound; the warning device 120 may also be controlled to send warning information, for example, send the water accumulation condition of the ship to equipment such as a smart phone of a shipowner or a crew member in a form of a short message or a push message, so as to remind relevant personnel of paying attention to the water accumulation condition on the deck of the ship in time.

In some embodiments, when the alerting device 120 is a mobile device, the processor 130 may be connected to the alerting device 120 through wireless communication. For example, the ship can be connected to the internet, and when the accumulated water level reaches a preset height, the warning information can be sent to a shipowner or a mobile device carried by a crew through the internet.

In some embodiments, the processor 130 may further obtain location information of the mobile device and the ship, respectively, determine a distance between the mobile device and the ship, and when the distance is smaller than a preset distance threshold, indicate that a shipowner or a crew carrying the mobile device is near or on the ship, and at this time indicate that the shipowner or the crew has learned alarm information about the situation of water accumulation at the deck of the ship, may control the alarm device to stop giving an alarm to the crew. Wherein, this preset distance threshold value can be decided according to the ponding condition of boats and ships deck department. For example, when the water accumulation condition at the deck of the ship is serious, the preset distance threshold value is short; when the water accumulation condition at the ship deck is slight, the preset distance threshold value is longer.

In some embodiments, when a plurality of preset heights are set on the ship, and each preset height corresponds to at least one liquid level sensor 110, the processor 130 may be further configured to receive sensing information of the liquid level sensors 110 corresponding to the plurality of preset heights, determine an alarm level corresponding to the water level height of the accumulated water on the deck of the ship according to the sensing information of each liquid level sensor 110, and control the alarm device 120 to perform an alarm corresponding to the alarm level, where the sensing information is related to a relative position between the liquid level sensor 110 corresponding to the preset height and the water level height of the accumulated water.

The sensing information of the liquid level sensor 110 corresponding to each preset height is related to the relative position of the liquid level sensor 110 and the height of the water level of the current accumulated water. For example, there are three level sensors 110, sensor A1, sensor A2 and sensor A3, which correspond to a preset height H1, a preset height H2 and a preset height H3, respectively, where H1 is greater than H2 and H2 is greater than H3. Supposing that the water level height of the accumulated water is H4, if H4 is less than H3, the induction information of A1, A2 and A3 indicates that the accumulated water does not reach; if H4 is larger than H3, but H4 is smaller than H2, the induction information of A1 and A2 does not indicate to reach, and the induction information of A3 indicates to reach; if H4 is greater than H2, but H4 is less than H1, then A1 indicates not reached, and A2 and A3 indicate reached; if H is greater than H1, then A1, A2, and A3 are all indicated to be reached.

According to the sensing information of each liquid level sensor 110, the approximate range of the water level height of the current accumulated water can be judged, so that the corresponding alarm level is determined according to the water level height of the accumulated water. For example, as in the above embodiment, there are three level sensors 110, sensor A1, sensor A2 and sensor A3, and there are four warning levels, W0, W1, W2 and W3. When all the A1, the A2 and the A3 indicate that the water is not reached, the corresponding alarm level is W0 and is used for indicating that 'no water is fed in and no attention is needed'; when the indication of A1 and A2 is not reached and the indication of A3 is reached, the corresponding alarm level is W1 and is used for indicating that 'the deck is water inlet and needs to be noticed'; when the indication A1 does not reach, and the indication A2 and the indication A3 reach, the corresponding alarm level is W2, which is used for indicating that 'more accumulated water is needed to be treated'; when the indication of A1, A2 and A3 is reached, the corresponding alarm level is W3, which is used to indicate "there is a risk, and processing is urgently needed".

According to different alarm levels, different alarm processing can be respectively carried out. For example, as in the above embodiment, there are four alert levels of W0, W1, W2, and W3. When the alarm level is W0, no alarm can be performed; when the alarm level is W1, only one time of alarm information needs to be sent to the mobile equipment of the shipowner or the crew; when the alarm level is W2, a section of alarm sound can be sent out after the alarm information is sent to the mobile equipment, so that the reminding strength is improved; when the warning level is W3, a continuous warning sound needs to be sent out until the owner or the crew receives the relevant warning information after sending the warning information to the mobile device.

It should be understood that the above embodiments are all exemplary embodiments, and in other embodiments, other arrangements may be adopted, and the present application is not limited thereto.
