Description

Technical Field

[0001] This application relates to the field of underwater buoy equipment technology, and in particular to a low-cost underwater equipment water level indicator. Background Technology

[0002] Currently, GPS positioning devices are available for surface salvage and location, but due to the need to carry an underwater standby power supply and the pressure resistance and sealing of communication equipment, the devices are large in size and weight, and expensive, resulting in very few underwater moorings using GPS positioning for guidance and search.

[0003] Currently, underwater mooring equipment is generally painted in bright colors and equipped with flashlights or flags to improve surface search efficiency. Most underwater mooring equipment recovery also uses a hydroacoustic release device to measure the distance between the mooring device and the recovery vessel, but it cannot determine the location. Moreover, once the release device rises to the vicinity of the surface, communication is lost, and the distance of the mooring device at the surface cannot be displayed.

[0004] The above factors mean that most current searches for the surface location of underwater moorings rely mainly on visual searches by crew members, which is very inefficient. Summary of the Invention

[0005] The technical solution adopted in this invention is to improve the efficiency of underwater buoy location search and reduce the risk of equipment loss. Therefore, this invention provides a low-cost underwater equipment surfacing positioning device.

[0006] This invention provides a low-cost underwater equipment water level indicator, comprising: The BeiDou positioning module is used to receive satellite positioning signals, acquire positioning information, and output it. The radio frequency communication module is used to respond to the IO enable control signal of the microcontroller control circuit, the control signal being generated based on the positioning information of the Beidou positioning module; The microcontroller control circuit communicates with the Beidou positioning module and the radio frequency communication module via serial port.

[0007] In one embodiment, the microcontroller control circuit is further configured to implement: After the microcontroller control circuit detects invalid positioning data, it sets the control IO level low, controls the radio frequency communication module to enter a sleep state to reduce power consumption, and at the same time, the Beidou positioning module stops serial port output and enters low-power receiving mode when there is no signal.

[0008] In one embodiment, the device is further configured to: After the equipment is removed from the water, the Beidou positioning module receives the satellite positioning signal and then enters normal operation. Within a preset time, it acquires positioning information and outputs valid positioning data. After receiving the valid positioning data, the microcontroller control circuit sets the control IO level high, wakes up the radio frequency communication module, and transmits the valid positioning data.

[0009] In one embodiment, the power consumption of the low-power receiving mode is below 100uW.

[0010] In one implementation, the preset time is 30 seconds.

[0011] By adopting the above technical solution, the present invention has at least the following advantages: The small-volume, low-cost underwater positioning device provided by this invention, after being attached to a mooring device, can perform its own BeiDou positioning and use wireless devices to transmit its own location information after surfacing with the device, indicating the location of the mooring device and guiding the retrieval, greatly reducing the time of searching the sea surface for mooring recovery and preventing the device from being lost.

Detailed Implementation

[0013] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0014] While exemplary embodiments of the invention are shown in the accompanying drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey its scope to those skilled in the art. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] According to an embodiment of the present invention, a low-cost underwater equipment water level indicator device and apparatus are provided, such as... Figure 1 As shown, it includes: The BeiDou positioning module is used to receive satellite positioning signals, acquire positioning information, and output it. The radio frequency communication module is used to respond to the IO enable control signal of the microcontroller control circuit, the control signal being generated based on the positioning information of the Beidou positioning module; The microcontroller control circuit communicates with the Beidou positioning module and the radio frequency communication module via serial port.

[0016] In this embodiment, the microcontroller control circuit is further used to implement: After the microcontroller control circuit detects invalid positioning data, it sets the control IO level low, controls the radio frequency communication module to enter a sleep state to reduce power consumption, and at the same time, the Beidou positioning module stops serial port output and enters low-power receiving mode when there is no signal.

[0017] In this embodiment, the device is further used to achieve: After the equipment is removed from the water, the Beidou positioning module receives the satellite positioning signal and then enters normal operation. Within a preset time, it acquires positioning information and outputs valid positioning data. After receiving the valid positioning data, the microcontroller control circuit sets the control IO level high, wakes up the radio frequency communication module, and transmits the valid positioning data.

[0018] In a specific application example, the key to the position display device lies in the system power consumption control strategy. This strategy controls system power consumption by putting the radio frequency circuit into sleep mode, reducing the battery capacity, thereby controlling the size and weight of the device and achieving miniaturization and cost reduction.

[0019] The system power consumption control method involves using a single chip to receive the positioning output data from the BeiDou positioning module. After the equipment is submerged in water, the BeiDou positioning module cannot receive satellite positioning signals, and the module outputs empty data. Figure 2 As shown.

[0020] When the microcontroller detects invalid positioning data, it sets the control I / O level low, putting the RF communication module into sleep mode to reduce power consumption. Simultaneously, the BeiDou module stops serial port output and enters low-power receiving mode when there is no signal. At this time, the system power consumption is below 100uW. After the equipment is brought out of the water, the Beidou positioning module receives the satellite positioning signal. After the module enters normal operation, it acquires and outputs the positioning information within 30 seconds. After the microcontroller receives the valid positioning data, it sets the control IO level to high, wakes up the radio frequency communication module, and forwards the positioning data to the wireless communication module for transmission. The nearby equipment salvage vessel will then receive the underwater location information.

[0021] Compared with the prior art, this embodiment has at least the following advantages: 1) This invention presents a low-cost underwater equipment water positioning device. The device consists of a low-cost Beidou positioning module, an RF communication module, and a microcontroller control circuit. The system power consumption control strategy is designed, and the power consumption of the system is controlled by putting the RF circuit into sleep mode, thereby reducing the battery carrying capacity. This controls the size and weight of the device, achieving miniaturization and cost reduction.

[0022] 2) This invention addresses the challenge of surface search for equipment during the recovery of current marine observation moorings. The invention features a simple circuit, small size and weight, minimal impact on the underwater mooring, low cost, long standby time, and can be deployed on existing mooring equipment. It begins operation after surfacing with the mooring during recovery, quickly acquiring BeiDou positioning information and transmitting it to the mother ship. This enables the mother ship to accurately locate the equipment on the surface, significantly reducing surface search time and success rate, lowering the difficulty of equipment search, and minimizing the risk of equipment loss. It has significant potential for widespread application and economic benefits.
