Description

Technical Field

[0001] The present invention relates to a system and method for collecting, storing and transmitting ocean buoy data. Background Art

[0002] Marine environmental monitoring is an important means of understanding the quality of the marine environment. As an automated monitoring platform, ocean buoys can effectively operate in harsh sea conditions and are considered an important component of modern three-dimensional marine environmental monitoring systems.

[0003] At present, the offshore ten-meter ocean buoy is an important automatic ocean observation station. The buoy's conventional data collection system can be equipped with 3 to 5 types of ocean water quality measurement sensors. The collected parameters include water temperature, salinity, pH value, chlorophyll, turbidity, flow rate, nitrate, etc. After the collection is completed, the data is intercepted, packaged, stored and sent to the shore-based receiving station server.

[0004] As scientific research institutions' demand for observing ocean water quality continues to increase, multi-channel nutrient meters, laser particle size analyzers, online spectrometers, online fluorescence chlorophyll analyzers, and online algae analyzers have begun to be used on offshore ten-meter ocean buoys. These sensors have the advantages of high measurement accuracy and multiple data parameters. However, the more sensors are mounted, the higher the power consumption requirements for the buoy. At the same time, the buoy data collector is limited in data length during transmission; or due to limited functions of the acquisition processor, the sensor acquisition accuracy may be lost or key status parameters may have to be discarded and transmitted back to the shore-based receiving station server. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides an ocean buoy data collection, storage and transmission system and method, so as to achieve the purpose of network data transmission of ten-meter offshore ocean buoys, avoiding data loss or loss of data accuracy when transmitting large amounts of data, and providing a new idea for the transmission of large amounts of data and high-precision original data of ten-meter offshore buoys.

[0006] To achieve the above object, the technical solution of the present invention is as follows:

[0007] A marine buoy data acquisition, storage and transmission system includes a buoy and multiple underwater sensors located on the buoy. The underwater sensors include a built-in sleep mode sensor and a non-sleep mode sensor. The built-in sleep mode sensor transmits data to a control memory via a multi-channel serial port server and a network cable. The non-sleep mode sensor stores data to the control memory via a first USB to 485 connection cable. The control memory controls the operation of the non-sleep mode sensor via a second USB to 485 connection cable and a 485 circuit breaker. The control memory stores data in a TF card. The multi-channel serial port server transmits data to a shore-based receiving station server via a network cable, a 4G router, and a 4G antenna. A power system on the buoy supplies power to the built-in sleep mode sensor, the control memory, the multi-channel serial port server, the 485 circuit breaker, and the 4G router.

[0008] In the above solution, the control memory includes one serial port channel, four USB channels, one Ethernet port channel and a built-in TF card slot, and the TF card is placed in the TF card slot.

[0009] In the above solution, all serial ports of the multi-channel serial port server support RS232 and RS485 functions.

[0010] In the above solution, the 4G router adopts an industrial-grade VPN router, which supports two access modes: serial port and Ethernet port.

[0011] In the above solution, the 4G antenna adopts a dual-band antenna, supporting frequencies 698-960 / 1710-2700.

[0012] A method for collecting, storing, and transmitting ocean buoy data, using the above-mentioned ocean buoy data collection, storage, and transmission system, includes the following steps:

[0013] Step 1: Configure the underwater sensor. Set the built-in sleep mode sensor to cycle working mode and connect it to the control memory through a multi-channel serial port server. Connect the non-sleep mode sensor to the control memory using a 485 circuit breaker and a USB to 485 cable.

[0014] Step 2: Configure a multi-channel serial port server and ensure that the baud rate of the multi-channel serial port server is consistent with that of the underwater sensor.

[0015] Step 3: Use the power system to supply power to the built-in sleep mode sensor, control memory, multi-channel serial port server, 485 circuit breaker and 4G router respectively;

[0016] Step 4: The control memory obtains the data of the built-in sleep mode sensor through the multi-channel serial port server and stores it in the TF card; the control memory controls the 485 circuit breaker to power on the non-sleep mode sensor through the USB to 485 connection line. After the acquisition is completed, the control memory reads the non-sleep mode sensor data through the USB to 485 connection line according to the Modbus protocol and stores it in the TF card;

[0017] Step 5: After the data storage is completed, the control memory uses two methods: one-way data synchronization and port forwarding to send the sensor data to the shore-based receiving station server through the 4G router. The shore-based receiving station server uses different ports to synchronize data ports for storing the original sensor data and stores them in the server's designated location.

[0018] When the port forwarding method forwards sensor data, the control memory acts as the client, the shore-based receiving station server acts as the server, and the port-to-serial port software is used to convert the sensor data from the port into serial port data, and the serial port tool is used to display the underwater sensor data content.

[0019] In a further technical solution, in step 4, the mode in which the sleep mode sensor actively sends data outward controls the memory to only receive data and does not perform other operations; and the control memory actively requests data from the non-sleep mode sensor.

[0020] In a further technical solution, in step five, the data content is unidirectionally synchronized to the shore-based receiving station server, and the file content in the TF card in the storage controller is completely copied; the port forwarding method can not only forward the sensor data, but also realize the function of configuring the underwater sensor parameters.

[0021] Through the above technical solution, the ocean buoy data collection, storage and transmission system and method provided by the present invention have the following beneficial effects:

[0022] The present invention adopts a one-way data synchronization method, and the local files are copied to the shore-based receiving station server files. When the file content in the local folder changes, the remote shore-based receiving station server also changes accordingly.

[0023] One-way data synchronization has the following advantages:

[0024] 1. One-way synchronization, that is, the sensor data on the buoy side can only be copied to the shore-based receiving station server in one direction. The data changes on the shore-based receiving station server will not affect the data collected and stored on the buoy side.

[0025] 2. Synchronize file content. When the network signal is interrupted, the newly generated data is stored in the TF card. When the network is restored, only the incremental content of the file is synchronized instead of copying all of it, which saves data storage space and storage efficiency.

[0026] In addition, the present invention also adopts port forwarding to transmit data. While forwarding sensor data, the port forwarding method can also realize the function of configuring underwater sensor parameters, such as changing the sampling interval, sampling content, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for describing the embodiments or the prior art.

[0028] Figure 1 This is a schematic diagram of an ocean buoy data collection, storage and transmission system disclosed in an embodiment of the present invention. DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] The present invention provides a system and method for collecting, storing and transmitting ocean buoy data. Figure 1 The system shown in the figure adopts two methods: one-way data synchronization and port forwarding. The sensor data is sent to the shore-based receiving station server through a 4G router. The one-way synchronization method can ensure that the data reception rate reaches 100%; the port forwarding method can also realize remote control of the sensor, change the sensor configuration and other operations.

[0031] In this embodiment, 10 underwater sensors are configured on a 10-meter offshore buoy, wherein underwater sensors No. 1-8 are sensors with built-in sleep mode, and underwater sensors No. 9-10 are sensors without sleep mode.

[0032] The built-in sleep mode sensors No. 1-8 transmit data to the control memory through the eight-channel serial port server and the network cable. The non-sleep mode sensors store data to the control memory through USB to 485 cable 1. The control memory controls the operation of the non-sleep mode sensors No. 9-10 respectively through USB to 485 cable 2 and 485 circuit breakers 1 and 485 circuit breakers 2; the control memory stores data in the TF card, and the eight-channel serial port server transmits the data to the shore-based receiving station server through the network cable, 4G router, and 4G antenna; the power system on the buoy supplies power to the built-in sleep mode sensor, control memory, multi-channel serial port server, 485 circuit breaker, and 4G router.

[0033] In this embodiment, the control memory includes one serial port channel, four USB channels, one Ethernet port channel and a built-in TF card slot, and the TF card is placed in the TF card slot.

[0034] The serial ports of the multi-channel serial device server all support RS232 and RS485 functions. The serial ports can work independently in full-duplex without interfering with each other. They can be configured with different baud rates and support dual-port network switch functions. They can also be used as switches.

[0035] The 4G router uses an industrial-grade VPN router, offering stability, reliability, and security. It supports both serial and Ethernet access. The 4G antenna uses a dual-band antenna, supporting frequencies of 698-960 / 1710-2700. A TF card is used for local data storage in the controller memory, supporting up to 128GB.

[0036] A method for collecting, storing, and transmitting ocean buoy data, using the above-mentioned ocean buoy data collection, storage, and transmission system, includes the following steps:

[0037] Step 1: Configure the underwater sensors. Set the sleep mode sensors No. 1-8 to cycle working mode and connect them to the control memory through an eight-channel serial port server. Connect the non-sleep mode sensors No. 9-10 to the control memory using a 485 circuit breaker and a USB to 485 cable.

[0038] This includes setting the sensor data output frequency and format, and the sensor entering sleep mode after data acquisition is completed (if there is no sleep mode, the power is cut off through the 485 circuit breaker control), thus maintaining data quality while minimizing the energy loss of the buoy power system.

[0039] Step 2: Configure an eight-channel serial server and ensure that the baud rate of the eight-channel serial server serial port is consistent with that of the underwater sensor serial port to ensure normal data transmission.

[0040] Step 3: Connect the power system to the built-in sleep mode sensor, control memory, eight-channel serial port server, 485 circuit breaker, and 4G router. The power system provides the overall power needs of the buoy. Strictly check the power system wiring method to ensure that incorrect or reverse connections are not allowed.

[0041] Step 4: The control memory obtains the data of the built-in sleep mode sensors No. 1-8 through the eight-channel serial port server and stores it in the TF card. The built-in sleep mode sensors No. 1-8 actively send data outward. The control memory only receives data and does not perform other operations;

[0042] The control memory controls the 485 circuit breaker to power on the No. 9-10 non-sleep mode sensors through the USB to 485 connection line. After the acquisition is completed, the control memory reads the No. 9-10 non-sleep mode sensor data according to the Modbus protocol through the USB to 485 connection line and stores it in the TF card; the control memory actively requests the data of the No. 9-10 non-sleep mode sensors.

[0043] Step 5: After the data storage is completed, the control memory uses two methods: one-way data synchronization and port forwarding to send the sensor data to the shore-based receiving station server through the 4G router. The shore-based receiving station server uses different ports to synchronize the data port for storing the original sensor data and stores it in the server's designated location. The data content that is one-way synchronized to the shore-based receiving station server completely copies the file content in the TF card in the storage controller.

[0044] When the port forwarding method forwards sensor data, the control memory acts as the client and the shore-based receiving station server acts as the server. The port-to-serial port software is used to convert the sensor data from the port into serial port data, and the serial port tool is used to display the underwater sensor data content. The port forwarding method can not only forward the sensor data, but also realize the function of configuring the underwater sensor parameters.

[0045] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
