- Arjun Chennu Et AI "A diver operated hyperspectral imaging and topographicsurveying System for automated mapping of benthic habitats", Scientific Reports, Vol. 7, No. 1, August 2, 2017 (2017-08-02), XP055660413, DOI: 10.1038 / S41598-017-07337-y discloses an underwater device by means of which recordings were made from the underwater floor.
- the underwater device has, inter alia, a hyperspectral camera, sensors and a computer.
- the object of the invention is also to provide a method when operating an underwater device, in which the risk of damage to the electrical loads when operating the underwater device is reduced.
- the object is achieved by a method when operating an underwater device, in which a sensor value is detected by at least one sensor of the underwater device and, based on the detected sensor value, it is determined whether there is a dangerous state for an electrical consumer of the underwater device, and an electrical one by the power distribution unit Connection between the electrical consumer and an electrical energy source of the underwater device is disconnected when a hazardous condition is present.
- the underwater device according to the invention has the advantage that it is actively checked whether there is a dangerous state in which an electrical consumer can be damaged. In the event that it is determined that a dangerous state is present, damage to the electrical consumer can be prevented in that the energy distribution unit disconnects the electrical connection between the electrical energy source and the electrical consumer. This reduces the risk that the electrical consumer will be damaged if water, for example, due to insufficient sealing, a cavity of the underwater device in which the electrical loads are arranged enters and / or the humidity in the cavity rises. In operation, the underwater device can be arranged partially or completely in the water. When examining a water floor at great depth, it is advisable that the underwater device is completely immersed in the water. The underwater device can be used to study marine and freshwater ecosystems.
- the energy distribution unit can have a control device.
- the control device can have a processor and / or evaluate the sensed sensor value.
- the control device can determine, based on the detected sensor value, whether a dangerous state is present.
- the control device can cause the electrical energy source to be disconnected from the electrical consumer.
- no electrical energy can be supplied to the electrical consumer if a dangerous state is present. This can prevent the electrical consumer from being damaged in a simple manner.
- the energy distribution unit serves to distribute the electrical energy provided by the electrical energy source to the electrical consumers of the underwater device. Accordingly, the energy distribution unit enables the electrical consumer to be supplied with electrical energy.
- the energy distribution unit can have a switching device by means of which the electrical connection between the electrical energy source and the electrical consumer can be separated.
- the switching device can have a multiplicity of switches by means of which the electrical loads can be separated from the electrical energy source separately and / or independently of one another.
- a switch position of the switch can be set accordingly by the control device of the energy distribution unit in order to establish an electrical connection between the electrical energy source and the to manufacture or disconnect electrical consumers.
- the number of switches can correspond to the number of electrical consumers.
- the energy distribution unit can generate a switch-off message and the switch-off message can be transmitted to the electrical consumer before the electrical connection between the electrical energy source and the electrical consumer is disconnected. This can prevent the electrical consumer from being suddenly switched off. The electrical consumer thus still has time to take precautions, for example to avoid data loss. After receiving the switch-off message, the electrical consumer can cause processing to be stopped and intermediate results to be saved.
- the energy distribution unit waits for a predetermined period of time after the switch-off message has been transmitted before the electrical connection between the electrical energy source and the electrical consumer is separated. As explained above, the electrical consumer can thus be given time to complete the machining process and / or to save the intermediate results. As an alternative or in addition, the energy distribution unit can, after transmitting the
- Switch-off message wait for feedback from the electrical consumer before the electrical connection between the electrical energy source and the electrical consumer is disconnected. In this case, it is ensured that the processing process is completed and / or the intermediate results are saved, because the electrical connection between the electrical energy source and the electrical consumer is only disconnected after the return information has been received.
- the energy distribution unit can wait after the switch-off message has been transmitted until a current intensity through the electrical consumer has fallen below or exceeded a predetermined threshold value before the electrical connection between the electrical energy source and the electrical consumer is disconnected.
- the energy distribution unit in particular the control device of the energy distribution unit, can determine whether processing operations are still running in the electrical consumer. It is therefore ensured that the electrical consumer is only disconnected from the electrical energy source when the electrical consumer has completed all processing operations.
- the energy distribution unit, in particular the control device of the energy distribution unit can examine the detected sensor value to determine whether a dangerous condition exists.
- the energy distribution unit in particular the control device of the energy distribution unit, can determine a dangerous state if the detected sensor value deviates from a predefined or predefinable limit value or is outside a limit range.
- the detected sensor value can be above a predefined or predefinable limit value or is outside a limit range.
- the detected sensor value can be above a predefined or predefinable limit value or is outside a limit range.
- the sensor value can be detected by at least one sensor connected to the energy distribution unit.
- the sensor can be connected directly to the control device.
- the control device of the power distribution unit can generate an alarm message if a dangerous condition exists.
- the alarm message can be placed in a queue and, as described in more detail below, as part of a
- Processing process can be processed by the energy distribution unit, in particular the control device of the energy distribution unit.
- a dangerous state can be determined particularly easily if the current supplied to the electrical consumer or the voltage applied to the electrical energy source or to the electrical consumer is determined by means of the sensor. By observing the current and / or the voltage, the control device of the energy distribution unit can infer whether a dangerous condition exists.
- Energy distribution unit cause current values to be recorded for a predetermined first and a predetermined second time period.
- the second time period is longer than the first time period.
- the current values recorded during the first time period can be used. .
- the underwater device can have a sensor unit which has at least one sensor and a sensor control device.
- the sensor control device determines that a dangerous state is present when the detected sensor value deviates from a predefined or predefinable limit value or is outside a limit range.
- the detected sensor value can be above the limit value and / or outside the limit range when a dangerous state is present.
- the sensor controller can be a processor.
- the information that a dangerous state is present can be transmitted from the sensor control device to the energy distribution unit, in particular the control device of the energy distribution unit.
- the sensor control device can generate an alarm message which is transmitted to the energy distribution unit.
- a communication protocol for communicating between the energy distribution unit and an electrical consumer, in particular a control device of the underwater device has a publishing / subscribing mechanism.
- the message to be transmitted can be published in a data channel.
- the message can be received from the data channel.
- the control device of the underwater device can have a receiving means for receiving the messages transmitted by the energy distribution unit.
- the publish / subscribe mechanism offers the advantage that the energy distribution unit and the electrical consumer do not have to be assigned any fixed addresses, in particular IP addresses, in the network of the underwater device and / or that the communication partners have the address, in particular the IP address, of the other communication partner do not need to be known so that they can communicate with each other.
- the network can be an Ethernet network.
- the communication protocol used for data communication can include the Message Queue Telemetry Transport Protocol (MQTT).
- MQTT Message Queue Telemetry Transport Protocol
- the control center can be designed in such a way that it sends the messages published in the data channel to at least one receiving means that have subscribed to the data channel.
- a control device of the underwater device can have the control center.
- the sensor control device can be designed in such a way that it publishes an alarm message in a data channel when a dangerous state is present.
- the energy distribution unit is designed in such a way that it receives the alarm message from the data channel and then disconnects the electrical connection between the electrical consumer and the electrical energy source. To receive the alarm message, the energy distribution unit can have the aforementioned receiving means.
- Such a procedure offers the advantage that, from the point of view of the energy distribution unit, it is only relevant whether an alarm message has been published in the data channel. In contrast, it is irrelevant for the energy distribution unit who published the alarm message in the data channel.
- components of the underwater device other than the sensor control device can also publish alarm messages in the data channel without this having any difference to the functioning of the energy distribution unit. Accordingly, the sensor control device can be exchanged and / or further sensors can be added without changes to the energy distribution unit being necessary. This simplifies the operation of the
- the switch-off message described above can be transmitted in the same way as the alarm message.
- the control device of the energy distribution unit can publish the switch-off message in another data channel.
- a receiving means of the electrical consumer who has subscribed to the data channel receives the switch-off message.
- the underwater device can have an electrical display device.
- the electrical display device can be a
- the underwater device can have an operating unit which is electrically connected to the energy distribution unit.
- the user in particular divers, can enter commands for the underwater device by means of the operating unit. So can cause the power distribution unit to selectively establish or disconnect the electrical connection between the electrical consumer and the electrical energy source or to put the electrical consumer and / or the electrical display device into a sleep mode or the electrical consumer and / or the electrical display device are transferred into an energy-saving mode.
- the user in particular diver, can select the desired operating state from the aforementioned operating states of the underwater device by pressing the operating unit for different lengths of time.
- the electrical loads are not shut down, but instead are brought into a state in which they require little electrical energy.
- the electrical consumers are switched to a mode in which they cannot perform their technical function, but the electrical consumers are not switched off.
- the electrical loads can be transferred from sleep mode to functional operation more quickly than from the switched-off state.
- the sleep mode is useful when the underwater device is not to be used to take pictures of the water floor and, for example, the underwater device is to be transferred from one position to another position. As a result, the use time of the underwater device can be extended due to the energy saving in the sleep mode.
- the electrical consumption of the electrical consumer and / or the electrical display device is reduced.
- the brightness of the electrical display device can thus be reduced in the energy-saving mode.
- the usage time of the underwater device can be extended.
- the operating unit can be integrated into the display device.
- the operating unit can have operating buttons which are arranged on a housing of the display device. The user, in particular diver, can thus enter the commands directly via the control buttons. This is advantageous in that it is difficult to enter commands under water and simple input options are therefore required.
- the energy distribution unit cannot electrically separate the display device from the electrical energy source. This offers the advantage that the dangerous state can be displayed immediately to the user, in particular a diver. In addition, recommendations for the next steps, such as surfacing, can be given to the user, in particular divers, via the display device, in order to prevent damage to the electrical loads of the underwater device. Alternatively, it is possible for the energy distribution unit to disconnect the display device from the electrical energy source when a dangerous state is present.
- the sensor can be used to determine a temperature or a humidity or a pressure within a cavity of the underwater device. If the underwater device has a plurality of sensors, the temperature and / or humidity and / or the pressure within the cavity of the underwater device can be determined with the sensors. In addition, a sensor can be present, by means of which, as described above, the current in the electrical consumer and / or the voltage applied to the electrical consumer is detected. The sensor or sensors can be electrically connected directly to the control device of the underwater device. The sensor value can be determined by at least one sensor of the sensor unit of the underwater device and / or at least one sensor of the energy distribution unit.
- the underwater device can have a lighting device, in particular an LED display, for displaying the operating state of the underwater device.
- the lighting device can have at least one lighting means, in particular an LED.
- the lighting device is advantageous because visibility is often poor under water, so that the diver can easily be informed of the operating state of the underwater device by the lighting device.
- the operating status can be displayed in a simple manner by means of different colors of the LED and / or brightness and / or by flashing.
- the electrical energy source can have a multiplicity of batteries and / or be of modular design.
- the modular design has the advantage that the energy source can be exchanged in a simple manner.
- the energy source can be releasably connected to a housing of the underwater device.
- the energy source can be attached to and / or in the housing.
- the connection can be made mechanically and / or electrically.
- the energy source can be directly connected to the housing in a form-fitting and / or force-fitting manner be connected.

- the electrical consumer can be the sensor control device of the underwater device.
- the electrical consumer can be another control device which is arranged outside the energy distribution unit.
- the electrical consumer can be an electrical component of another component of the underwater device.
- the underwater device can thus have a position determination unit for determining the actual position of the underwater device.
- the position determination unit can have at least one electrical consumer.
- the electrical loads can be position determination means of the position determination unit that are required for position determination.
- the underwater device can have an image acquisition unit for image acquisition of the water floor.
- the image capture unit can have at least one electrical load.
- the image acquisition unit can have a hyperspectral camera.
- the image capture unit can have a color camera, in particular an RGB camera. Both the color camera and the hyperspectral camera create an image of the water floor.
- a hyperspectral camera is a camera that records multispectral data in very narrow spectral bands of visible light, near and mid-infrared. Hyperspectral cameras thus enable a high spectral resolution of the object-specific signatures in more than 15, but generally in 30-200 adjacent channels and thus enable the documentation of an almost continuous spectrum for each picture element.
- the color camera is not a hyperspectral camera.
- the color camera differs from the hyperspectral camera in that it has fewer channels, in particular exactly three channels, than the hyperspectral camera. Accordingly, with a color camera, the observed object cannot be resolved as highly spectrally as with a hyperspectral camera.
- the underwater device can based on the captured images
- the underwater device can be designed in such a way that it can be actuated and / or operated and / or portable by hand. This means that the underwater device is not controlled by remote maintenance from a ship, but exclusively by the diver.
- the underwater device can be designed without a propeller. This means that the underwater device is driven exclusively by the diver.
- Underwater device thus has no drive motor for driving the underwater device.
- the underwater device can have a housing which encloses a cavity, the electrical consumer and the energy distribution unit being arranged in the cavity.
- the position determination unit can thus be arranged at least partially in the cavity.
- At least one sensor of the position determination unit can be arranged outside the cavity.
- the image acquisition unit in particular the hyperspectral camera and / or the color camera, can be arranged, in particular completely, within the cavity.
- the energy distribution unit can perform different tasks.
- the individual tasks can be prioritized differently. This means that the energy distribution unit processes the tasks with a higher priority than tasks with a lower priority. Appropriate prioritization can thus ensure that alarm messages are processed quickly by the energy distribution unit.
- the energy distribution unit can optionally perform a communication task or a current monitoring task or an energy control task for controlling the operating state of the underwater device or a processing task for processing messages, in particular or an indication task.
- the individual tasks are described in more detail below.
- the components, such as electrical consumers, of the underwater device can communicate with one another or with external devices in terms of data technology.
- the energy distribution unit can communicate with the electrical consumer in terms of data.
- the power distribution unit can respond to the message immediately after receiving a message, such as a request for the time, or the power distribution unit can place the message in the queue for processing, which is processed when the processing task described below is carried out.
- the energy distribution unit communicates with the electrical consumer by publishing a message in a data channel. This means that the message is available for the receiving means or all receiving means that have subscribed to the data channel.
- the energy distribution unit can thus receive the message when a receiving means of the energy distribution unit subscribes to the data channel.
- the receiving means can only receive messages from data channels to which they have subscribed.
- the image acquisition unit can transmit a message in a further data channel in order to notify that an image acquisition process is to take place.
- the control device in particular the receiving means of the control device, of the energy distribution unit receives the message and causes lighting of the underwater device to be switched off in order to prevent the illumination light from being detected by the image acquisition unit.
- control messages can be transmitted to the energy distribution unit when the communication task is carried out. In this way, a control message can be transmitted that an image recording process is to take place.
- the energy distribution unit ensures that the electrical connection between the electrical consumer, in particular the electrical consumer of the image capture unit, and the energy source is closed. In this way, it can be achieved in a simple manner that only the electrical loads that are actually required are electrically connected to the energy source.
- the energy distribution unit can, as already described above, determine current values for a predetermined first time period and for a predetermined second time period. In this case, based on the current values determined in the first period of time, it is determined whether a dangerous state exists.
- the current monitoring task when the current monitoring task is carried out, it is checked by determining the current whether the respective electrical consumer is switched on or off. When performing the current monitoring task, it can also be determined whether there is a short circuit. This is the case when a current value is detected which is above a predetermined threshold value.
- the operating state of the underwater device is set. For this purpose, it is monitored whether a control unit is operated. As a result of the actuation, the electrical connection between the electrical consumer and the electrical energy source can be established in a switch-on mode or disconnected in a switch-off mode or the electrical consumer and / or the electrical display device can be switched to sleep mode or the electrical consumer and / or the electrical Display devices can be switched to energy-saving mode.
- the messages in the queue can be processed. You can search for alarm messages and
- Action messages are differentiated.
- Alarm messages are messages that signal a dangerous state, so that the electrical connection between the electrical energy source and the electrical consumer is to be separated by means of the energy distribution unit.
- Action reports contain information for the recipient as to which action, such as switching off the recipient, will take place. Based on this information, the recipient can take further steps, such as storing data.
- a Alarm message published in the data channel.
- the receiving means of the control device of the energy distribution unit receives the alarm message and places it in the queue.
- the alarm message is processed in the processing mode of the energy distribution unit. During processing, the electrical consumer is disconnected from the electrical energy source and the dangerous state can be displayed on the electrical display device.
- the sensor control device determines that the pressure detected by the sensor in the flea space rises above a predetermined limit value, it is assumed, for example, that there is a leak and an alarm message is output in the data channel. After receiving the alarm message and placing it in the queue, it is processed by the energy distribution unit. The electrical consumers are disconnected from the energy source and it can be indicated to the diver that he should not dive any further in order to prevent more water from entering the flea space of the underwater device.
- alarm messages generated by the control device of the energy distribution unit can also be processed. These alarm messages can be generated if it is determined on the basis of the recorded current values that a dangerous condition exists.
- the status of a luminaire can be checked.
- it can be set whether or not at least one lighting means is lit.
- the setting of the lighting state of the luminaire can be dependent on the operating state of the underwater device and / or on the presence of a dangerous state.
- the underwater device is an underwater device that can be operated by divers.
- An underwater device that can be operated by diver is understood to be a device that can be operated by a diver in or under water. This means that the diver can move the underwater device in or under water and thus move it into the desired position in order to take pictures of the desired area of the water floor.
- the diver can operate the underwater device in or under water, in particular input appropriate commands in order to take pictures of the water floor.
