The invention relates to a main oil-passage no-pressure warning device of a hydraulic system, comprising a steering mechanism and a hydraulic pump group, wherein the hydraulic pump group comprises a first hydraulic pump group and a second hydraulic pump group. The main oil-passage no-pressure warning device is characterized in that: the first hydraulic pump group comprises an electric pump group,an oil box and an integrated valve block, wherein the integrated valve block is formed by installing a high-pressure manometer, a main oil-passage overflow valve, an oil-return passage overflow valve, an oil-return passage pressure relay, an electro-hydraulic reversing valve, a low-pressure manometer, a main oil-passage pressure relay and a special valve of a steering engine on an iron block, wherein an oil outlet of the oil box is connected with an oil suction hole of the electric pump group, an oil outlet of the electric pump group is connected with the electro-hydraulic reversing valve arranged on the integrated valve block to form a main oil passage, an oil return hole of the oil box is connected with the electro-hydraulic reversing valve to form an oil return loop after being connected with an oil-return filter, and the electro-hydraulic reversing valve is connected with the special valve of the steering engine. The main oil-passage no-pressure warning device of the hydraulic system monitors the pressure of the main oil passage of the hydraulic system and can know the oil-pressure condition of the main oil passage in time.

The invention discloses an integrated automatic driving system for unmanned ships, including: a sensing module for sensing the ship's navigation environment, and obtaining real-time channel, hydrology, ship's own status, and dynamic traffic environment information; a communication system for ships and Data and instructions are transmitted between shore bases and system modules; the data processing module is used to process the information obtained by the perception module; the decision-making module is used to identify the current operating situation and environment of the ship according to the data output by the data processing module, and select The action to be taken in the next step, and generate the corresponding operation instruction; the execution module is used to receive the operation instruction issued by the decision-making module and use the PID controller to control the propeller and rudder of the ship to change the motion state of the ship. This automatic driving integrated system for unmanned ships integrates functions such as sensing the environment, behavior decision-making, ship control, and remote control, which can greatly liberate manpower and ensure safe navigation of ships.

The invention discloses an LED fishing lamp fishing boat control system. According to the system, a computer-aided control mode is used, an MCU is used as a data processing center, and a touch screen is a control platform system for man-machine communication. The system comprises the following six sub-systems and is used for controlling the six sub-systems, including an LED fishing lamp direct-current power supply integrated control system, an LED fishing lamp telescopic rack control system, an LED fishing lamp cooling heat exchange control system, a fishing boat electric power supply control system, a fishery water area status monitor system and a fishing net deploying and retracting control system. The system can be used for carrying out high-efficiency multi-sea-state fishery fishing control for single-lamp high power and single-boat multi-lamp of the LED fishing lamp, and is especially suitable for the field of pelagic light trapping fishing with flexible manpower and automatic requirement.

The invention provides a device for measuring the gravity center of a waterborne carrier in a motion state. The device is characterized by being provided with four or more GNSS signal receiving devices, a posture sensor device and a CPU data recording and processing device, wherein the GNSS signal receiving devices are used for receiving a GNSS satellite signal in real time, and calculating the geographic coordinates of an observing point; two of the GNSS signal receiving devices are arranged in the heading direction of the waterborne carrier; the posture sensor device is used for acquiring the posture values of rolling, pitching and heaving of the waterborne carrier in real time; and the CPU data recording and processing device is connected with each GNSS signal receiving device and the posture sensor, and used for recording the observing value of each device in real time, and processing the observation values to obtain the coordinates of the gravity center of the waterborne carrier under a waterborne carrier coordinate system. Through adoption of the device and method for measuring the gravity center of the waterborne carrier, the gravity center position of the waterborne carriercan be obtained accurately in real time specific to the problems of irrationality and inaccuracy of an existing waterborne carrier gravity center determining method.
