  • Patent number: 12239109
    Abstract: In the breeding of aquatic products, keeping track of changes in the water quality environment is an urgent aquaculture problem to be solved. At present, single sensors are often used for data detection, and there is no coordination between the sensors or between sensors and actuators, resulting in a lack of a unified monitoring and control mechanism. The current invention discloses a holding tank monitoring system based on a wireless sensor network and a monitoring method provided thereof characterized by an unattended operation and automated execution by obtaining environmental data of a holding tank in real-time, and analyzing the data using a suitably trained machine learning algorithm and causing a control action on the actuator to perform a corrective action on the holding tank for optimal operation of the system.

  • Publication number: 20220141553
    Abstract: The present disclosure relates to a system for tracking, locating and retrieving fishing traps at sea, the system comprising a plurality of smart trap units and/or trap companion units in communication with a fishing vessel. The fishing vessel has onboard software for tracking the deployment and retrieval of said units, with the data being recorded and uploaded to a network service offering. The units are configured to assist with retrieval of the traps by comprising one or more releasable buoys that may be deployed after a pre-set time or in response to a command signal.

  • Publication number: 20220080805
    Abstract: The present invention discloses an improved system of monitoring logistics involved in marine transportation. The proposed system with the help of data acquisition component, humidity control component, temperature control component, power component, microcontroller, and user device automatically regulate the required temperature and humidity level within preset threshold and also transmits the information to the user's device. This system also allows to add additional sensors and environmental control components including but not limited to ambient light, vibration, sound, movement, oxygen, chemical levels, and more. The system also provides a communication interface coupled to the onboard micro controller, where the communication interface being operative to transmit a monitoring update message to end user device, in response to a transmission instruction from the onboard microcontroller.

  • Publication number: 20220081083
    Abstract: The present invention solves the foregoing problems by providing a control system comprising a remote control module in wireless communication with a cable reel module connected to a motor operated cable reel. Advantageously, the remote control module comprises a first user interface for entering instructions and a processor for transmitting the instructions to the cable reel module to extend or retract the cable and thus control the ascent or descent of an ROV attached to the cable. Due to the processor-controlled nature of the control system automated operations of ROV ascent and descent can be realised. Furthermore, the cable reel module itself is provided with a second user interface that can enact a manual override and emergency stop of the ROV motion in the event that the remote control aspect malfunctions or is being operated incorrectly.
