The bus chip is communicatively coupled to the sensor 100 in the underwater environment via the broadband bus 110 for receiving sensor data transmitted by the sensor 100 via the broadband bus 110 and transmitting the sensor data to the baseband chip. For the communication module serving as the non-gateway node, the baseband chip is used for transmitting the sensor data to the baseband chip of the communication module corresponding to the gateway node;

The baseband chip may be used to synthesize a baseband signal to be transmitted or decode a received signal, etc., and may be integrated on a communication module as a core part of the communication module. Specifically, the baseband chip in this embodiment may be a KS2300X baseband chip, which is a baseband processing chip used in a software radio (Software Defined Radio, SDR) scheme. The KS2300X integrates a high-efficiency application processor and two communication baseband processing subsystems, and can realize a dual-channel processing mode for communication module data and communication satellite data. Each communication baseband subsystem integrates a protocol processor, a general purpose DSP (Digital Signal Processing ) and a high performance vector DSP. An ASIC (Application Specific Integrated Circuit ) accelerator, which is commonly used in communication processing, is also integrated in the chip. With the aid of these accelerators, high throughput rate custom wireless communications can be achieved. The On-Chip interconnection bus (Network On Chip) is used to refer to the connection relationship between the systems or modules in the Chip, and is mainly used to realize the data exchange between the subsystems or functional modules in the Chip.
In this embodiment, the bus chip may specifically be a KY3001 chip, which is respectively configured on the communication module and the digital sensor, so as to implement data collected by the sensor to be transmitted to the bus interface of the communication module through an AUTBUS bus, where the AUTBUS bus is an industrial broadband bus standard, and can be at the bottom layer of the industrial internet, so as to implement high-bandwidth real-time interconnection and interworking of each industrial communication node.
Fig. 2 is a block diagram of a communication module for underwater environment sensing according to an embodiment of the present invention. As shown in fig. 2, communication module 200 includes baseband chip 210, bus chip 220, routing layer 230, and SCA architecture layer 240. Baseband chip 210 includes an ad hoc network channel 211 and a satellite communication channel 212.

The underwater environment in the present embodiment may be an ocean environment or the like, and particularly may be an underwater environment of a sea area which is 10 km away from the coast and which is not capable of communicating depending on the communication infrastructure, and the present embodiment is not particularly limited herein.
The communication module carrier can be used for carrying the communication module by using the existing ocean buoys, deep sea culture platforms, ocean scientific research floating platforms, ocean oil platforms or boats and the like in the ocean, so that the multipoint deployment of the communication module is realized, and a communication cluster is formed. For example, a communication module is deployed on the water portion of the ocean buoy, communication cables are fixed on cables connecting the underwater portion of the ocean buoy with the anchoring weights, and different sensors are arranged on the communication cables at different depths of water for acquiring ocean environment information of different layers of water. For a digital sensor arranged with a bus chip configured thereon, sensor data may be transferred via an AUTBUS bus to a bus interface of the communication module. The AUTBUS bus technology can solve the problem of sensor data transmission with different depths and different bandwidths, and can realize the transmission of the sensor data at 100Mbps at the depth of 500 meters or at 32Mbps at the depth of 1000 meters. Alternatively, for a KY3001 chip, the number of sensor nodes that can be accessed is 254. It is understood that the KY3001 chip is only one type of chip in the bus chips, and the number of accessible sensor nodes is 254, and cannot be defined as the number of accessible sensor nodes of all bus chips.
In one case, for the arranged analog sensor, its sensor signals are transmitted to the bus chip via the communication cable.
The bus chip of each communication module in this embodiment may be communicatively coupled to a plurality of sensors in an underwater environment via a broadband bus. The bus chip and the baseband chip may be connected by ethernet or PCIE (Peripheral Component Interconnect Express, high-speed serial computer expansion bus standard) communication. The bus chip receives sensor data transmitted by each sensor through the broadband bus and transmits the sensor data to the baseband chip.
Each communication module constructs an ad hoc network through a baseband chip. An ad hoc network is a peer-to-peer network that uses wireless communication technology, where nodes in the network act as routers for their neighbors (nodes in direct communication range) and communication between the nodes is achieved through node forwarding. In this embodiment, the communication modules are used as nodes of the ad hoc network, and each communication module is used as a router of its neighbor. Broadcast is a common operation in ad hoc networks, and broadcast delivers messages sent by one node to all other nodes in the network. The gateway nodes in the ad hoc network may be determined by a gateway election algorithm. Specifically, the network nodes in the ad hoc network belong to different clusters, each cluster comprises at least one alternative gateway node, and each alternative gateway node in the ad hoc network can autonomously elect a gateway node. The process of electing the gateway node may be triggered under a number of conditions, and the embodiment is not particularly limited. Gateway election may be triggered, for example, when an ad hoc network is up, when the network is restarted, or when an elected gateway node fails. When the gateway elects, each alternative gateway node needs to generate gateway elected parameters of the communication module, send the gateway elected parameters to other alternative gateway nodes in a multicast mode, and acquire the gateway elected parameters of the other alternative gateway nodes. And selecting one gateway node from the alternative gateway nodes of the autonomous network according to the magnitude of all gateway election parameters. There are many ways to generate gateway election parameters, for example, the gateway election parameters may be generated according to a machine code of the corresponding communication module or according to an IP address. And marking the communication module corresponding to the gateway node as a target communication module.
For a certain communication module, if the communication module is not a target communication module corresponding to the gateway node, the baseband chip of the communication module corresponding to the non-gateway node in the communication module broadcasts the sensor data to other communication modules in the ad hoc network. And the target communication module serving as the gateway node receives the sensor data and transmits the sensor data to the communication satellite through the ad hoc network channel corresponding to the communication module. The ad hoc network channel of the gateway node directly bridges the satellite channel through the ethernet interface. Therefore, the method and the system realize that the baseband chip of the communication module of the gateway node serving as the target communication module of the gateway node in the ad hoc network receives the sensor data of other communication modules, receives the sensor data transmitted by the bus chip in the communication module, transmits the received sensor data to the communication satellite so as to be connected with the communication satellite through a satellite channel, then transmits the sensor data to the satellite gateway station through radio waves, and finally transmits the sensor data to the data processing center through the ground network of the satellite gateway station. The communication satellite may be a space-time or low-orbit constellation.
Optionally, the bus chip may be further configured to configure bus bandwidths and transmission slots corresponding to the sensors with different water depths based on the configuration information, so that the sensors transmit sensor data with corresponding water depths using the configured bus bandwidths and transmission slots.
The bus chip on the communication module is used as a master bus chip, and the bus chip on the sensor is used as a slave bus chip. The configuration information may be written to the host bus chip by a write chip device. The master bus chip may manage the bus bandwidth and transmission time slots of the slave bus chip. The sensor data is transmitted by configuring bus bandwidths and transmission time slots for slave bus chips on sensors with different depths and adopting different bus bandwidths and transmission time slots, so that the problem of underwater sensor information transmission with different depths and different bandwidths is solved.
Optionally, the bus chip may further include an edge calculation module: and the edge calculation module is used for fusing the sensor data by utilizing a data fusion technology before transmitting the sensor data to the baseband chip and carrying out edge analysis based on a fusion result. Then, the sensor data after the edge analysis is transmitted to the baseband chip.
The sensor data may include, among other things, hydrologic data, pollution monitoring data, and the like.
Wherein the hydrologic data may include tidal, water temperature and salinity data of the ocean, etc.; the pollution monitoring data may include data information of marine pollutants, etc.
In this embodiment, the sensor is first used to collect data, then the data fusion technology is used to fuse the sensor data, and the fusion result is stored in the memory in the bus chip. Optionally, edge analysis may also be performed based on the fusion results. Because the transmission capacity of the satellite channel is limited, the data fusion and the edge analysis are carried out on the sensor data by utilizing the edge calculation module, so that the data quantity is reduced, and the data processing efficiency is improved.
Optionally, for the communication module serving as the gateway node, the baseband chip may be configured to send a failure message to the baseband chip of the communication module corresponding to each non-gateway node in the ad hoc network when the backhaul signal of the communication satellite is not received within a preset timeout period; for the communication module as a non-gateway node, the baseband chip is configured to receive the failure message, and determine to set a gateway node in the alternative gateway nodes in the ad hoc network.
In this embodiment, when only one node in the whole network is transmitted back to the data processing center through the satellite link, after the node fails, that is, no satellite return signal is received in a preset time, a gateway node is selected from the set alternative gateway nodes in the network, and an ad hoc network channel of the newly selected gateway node bridges a new satellite channel through an ethernet interface and enables the new satellite channel to perform communication.
Optionally, the baseband chip of the communication module corresponding to the non-gateway node is specifically configured to: after receiving the failure message, judging whether the communication module is a set alternative gateway node.
If the communication module is a set alternative gateway node, determining an alternative priority of the communication module, sending the alternative priority to baseband chips of other communication modules in the ad hoc network, receiving the alternative priority of other alternative gateway nodes in the ad hoc network, comparing the alternative priority with the alternative priority of other alternative gateway nodes, and sending an alternative priority comparison result to the baseband chips of other communication modules in the ad hoc network; and determining the gateway nodes in the alternative gateway nodes through the alternative priority comparison result.
If the communication module to which the baseband chip of the communication module corresponding to the non-gateway node belongs is not a set alternative gateway node, receiving an alternative priority and an alternative priority comparison result; and determining the gateway nodes in the alternative gateway nodes through the alternative priority comparison result.
The embodiment of the invention predesignates a plurality of alternative gateway nodes, applies for a plurality of satellite channels and establishes the corresponding relation between the alternative gateway nodes and the satellite channels. After failure of the gateway node, a new gateway node may be selected by the priority of the plurality of candidate gateway nodes. And establishing a bridging relation between the ad hoc network channel and the satellite channel through an Ethernet interface based on the corresponding relation between the gateway node and the satellite channel so as to enable the satellite channel corresponding to the new gateway node. The priority may be determined based on routes of the candidate gateway nodes and the ad hoc network center, and the closer the routes are, the higher the priority is.
In the case that the communication module is not the target communication module corresponding to the gateway node, the baseband chip of the communication module corresponding to the non-gateway node of the communication module is specifically configured to: and generating a forwarding message based on the second sensor data, acquiring the route information from the communication module to the target communication module, and transmitting the forwarding message to the target communication module according to the route information.
Illustratively, the baseband chip of the communication module corresponding to the non-gateway node may be specifically configured to: and generating a forwarding message based on the sensor data, and transmitting the forwarding message to the gateway node according to the route of the communication module corresponding to the gateway node to which the communication module belongs.

In the case that one communication module is a target communication module corresponding to a gateway node, a baseband chip serving as the communication module corresponding to the gateway node in the communication module may be specifically used for: and generating an uploading message based on the first sensor data and the second sensor data, transmitting the uploading message to a satellite channel through an ad hoc network channel corresponding to the target communication module, and transmitting the uploading message to a communication satellite through the satellite channel, wherein the ad hoc network channel bridges the satellite channel through an Ethernet interface.
