and the server is used for sending the seismic data to the client after receiving the seismic data.
Specifically, the client, i.e., the central client, is also called a client, and refers to a program corresponding to the server for providing local services to the client. The client side is used for a user to operate, when the user needs to acquire seismic data acquired by the node instrument, a request instruction for acquiring the seismic data is sent to the server through the client side, and then the server sends the request instruction to the node instrument through the LoRa gateway.
Specifically, a Long Range Radio (LoRa) gateway is also called an LoRa base station, and is a gateway device that uses the LoRa wireless modulation technique to implement Long Range data transmission. The LoRa gateway adopts the design of an industrial-grade 32-bit special network processor and a high-speed 4G wireless communication module, supports APN/VPDN wireless private network, supports LoRaWAN communication specification, supports GPS high-precision clock synchronization, and has the concurrent processing capacity of multiple frequency points and multiple channels. Through setting up the loRa gateway, the server will be from the request instruction that the client received to send to the loRa gateway, and the loRa gateway broadcasts the request instruction to the node appearance through wireless communication technology on, has realized the wireless transmission of node appearance and client.
Specifically, broadcasting is a way of information propagation, and means that a certain device in a network simultaneously sends data to all other devices in the network, and the range to which the data can be broadcasted is a broadcast domain. Correspondingly, according to the application, the LoRa gateway sends the request instruction to all the node instruments in the network simultaneously through the wireless transmission technology, and therefore wireless data transmission of the wireless node instruments is achieved.
Specifically, the node instrument is provided with an acquisition module and a 5G module, wherein the acquisition module is used for acquiring seismic information and performing analog-to-digital conversion on the seismic information so as to acquire seismic data, and the node instrument obtains the seismic data. The 5G module is used for registering an operator 5G network and establishing a new TCP connection with the server, namely the 5G module is connected with the server, so that the seismic data acquired by the node instrument can be sent to the server through the 5G module. In this embodiment, when the node instrument sends the acquired seismic data to the server node instrument through the 5G module and receives a request instruction sent by the LoRa gateway, the node instrument starts the acquisition module to acquire the seismic data, so as to acquire the seismic data, and sends the seismic data to the server through the 5G module. The 5G communication has the characteristics of high transmission speed and stable data transmission, so that the 5G module is adopted for transmitting the seismic data, the data loss can be reduced, the error rate is reduced, and the integrity of the real-time transmission of the seismic data can be effectively ensured.

In one embodiment, the request instruction includes a device code of the requested device;
the node instrument is also used for judging whether the equipment code is matched with the self code; and when the equipment code is matched with the self code, acquiring the seismic data, starting the 5G module, and sending the seismic data to the server through the 5G module.
Specifically, each node instrument has its own device code after leaving the factory, and the device codes of each node instrument are different. When a user needs to acquire seismic data acquired by a certain node instrument, a request instruction for acquiring the seismic data is sent through a client, and the request instruction comprises the equipment code of the requested equipment, namely the equipment code of the requested node instrument. The node instrument acquires a request instruction forwarded by the LoRa gateway and judges whether the equipment code of the equipment in the request instruction is matched with the self code; if the data is matched with the data, the node instrument is the node instrument which needs to acquire the seismic data by the client, an acquisition module and a 5G module in the node instrument are started, the acquisition module is used for acquiring the seismic data so that the node instrument can acquire the seismic data, the 5G module is used for registering a 5G network of an operator and establishing a new TCP connection with the server, and even if the 5G module is connected with the server, the seismic data acquired by the node instrument can be sent to the server through the 5G module. And then the node instruments transmit the acquired seismic data to the server through the 5G module, and the server transmits the received seismic data to the client so that the client can receive the seismic data of the corresponding node instruments. In the embodiment, the request instruction is sent through the client, that is, according to the on-demand use principle, when the user needs to acquire seismic data, the acquisition module is started to acquire the seismic data and the 5G module is started to perform data transmission; seismic data acquisition is not needed in real time, and the electric energy loss of the node instrument can be reduced, so that the service life of a battery of the node instrument is prolonged. And for the node instruments which are not requested by the client, the equipment codes contained in the request sending instruction are not matched with the own codes, so that the standby state is kept, and the power consumption of the node instruments is further reduced.
In one embodiment, the 5G module is configured to register with an operator 5G network and establish a new TCP connection with the server. Specifically, when the node instrument receives the request instruction, the 5G module is started, the 5G module registers the 5G network of the operator to realize wireless communication between the node instrument and the server, and the seismic data is sent to the server through the new TCP connection by establishing the new TCP connection, that is, reestablishing the new TCP connection by the 5G module, so as to further improve the stability of data transmission.
In one embodiment, the client is used for sending a request instruction for acquiring seismic data to the server in a message queue telemetry transmission mode;
the server is further used for sending the seismic data to the client in a message queue telemetry transmission mode.
Specifically, the Message queue Telemetry Transport, MQTT (Message queue Telemetry Transport), is a Message Transport protocol based on a publish or subscribe mode of a lightweight proxy, operates on a TCP protocol stack, and provides network connection guarantee of ordered, reliable, and bidirectional connection for the TCP protocol stack. And the message queue telemetry transmission has the following characteristics:
(1) the MQTT message bandwidth is small, and the design is reasonable and the implementation is carried out on a low-power system;
(2) messages on MQTT very simple remote sensor systems are implemented. Since most of the complex work is done on the server, the remote system can use its resources elsewhere.
(3) MQTT is used in mission critical sensor systems where any message sent is critical to acknowledgement and reception. MQTT allows the importance of a message to be defined by declaring its quality of service (QOS) level.
Therefore, the server and the client transmit data in an MQTT mode, protocol overhead can be reduced, electric energy loss of the client is reduced, and data transmission is stable and reliable.
In one embodiment, the request instruction further includes a frame header, a command code, a cyclic redundancy check code, and an end symbol, and the frame header, the device code, the command code, the cyclic redundancy check code, and the end symbol are arranged in sequence. Specifically, cyclic redundancy check code, that is, CRC8(cyclic redundancy check); the frame header occupies 1 byte for "$", the equipment coding of the node instrument is formed by coding 8-bit character codes, 8 bytes are occupied, 2 bytes are occupied by command codes, 1 byte is occupied by cyclic redundancy check codes, and 2 bytes are occupied by the end character of "\ r \ n" for carriage return and line change. For example, the command code is "61" and the CRC8 is a check value encoded in the first 11 characters of the instruction. The request instruction is formed by sequentially arranging the frame header, the equipment code, the command code, the cyclic redundancy check code and the end symbol, so that the node instrument can better judge whether the equipment code in the request instruction is matched with the self code when analyzing the request instruction. In one embodiment, the request command is composed of a frame header, a device code, a command code, a cyclic redundancy check code, and the end symbol arranged in sequence.
In one embodiment, the LoRa gateway is in a long connection state; and the server sends the request instruction to the LoRa gateway in a socket mode. Specifically, a long connection means that multiple data packets can be continuously transmitted over one connection, and during the connection holding period, if no data packet is transmitted, a link detection packet needs to be transmitted in both directions. A socket, is an abstraction of an endpoint for two-way communication between application processes on different hosts in a network. A socket is the end of a process's communication over a network and provides a mechanism for application layer processes to exchange data using a network protocol. From the position, the socket connects the application process to the application process, connects the network Protocol stack to the application program, is an interface through which the application program communicates by the network Protocol, is an interface through which the application program interacts with the network Protocol root, and the socket is a basic operation unit for supporting path communication of a TCP (Transmission Control Protocol)/IP (Internet Protocol) Protocol. In this embodiment, the server obtains the request instruction sent by the client, and sends the request instruction to the LoRa gateway in the long connection state in a pure socket manner, so that communication between the server and the LoRa gateway is realized.
In one embodiment, the node device is further configured to organize the seismic data according to a preset protocol format to form a seismic data block, and send the seismic data block to the server through the 5G module. Specifically, the seismic data collected by the node instrument comprises data such as data recording block size, data block sample point number, data block sampling rate, node coding and data block coding, namely the seismic data contains more data related to seismic information, therefore, the seismic data are organized according to a preset protocol format to form seismic data blocks, so that the seismic data can be regularly arranged, a client can better identify the seismic data, the loss of the seismic data blocks in the transmission process can be reduced, the error rate is further reduced, and the integrity of real-time transmission of the seismic data can be better guaranteed.
In one embodiment, the predetermined protocol format comprises a 48-byte header and a data block for each recording block, and the length of the data block is determined by the number of sampling points. Specifically, the preset protocol format is the format of the seismic data block. For example, if the number of samples is n, the data block length is 4n, and the data is represented by 4 byte floating point numbers. Another example is: if a floating point number of 500 samples is set, the data block length is 2000 bytes, and each record block length is 2048 bytes. The recording block in this embodiment refers to a seismic data block.
In one embodiment, the data structure of the block header is shown in table 1:
TABLE 1 Block header data Structure
Specifically, the data in table 1 is a block header of 48 bytes as an example, and the position in table 1 represents the number of bytes occupied by the data with the corresponding sequence number and the corresponding byte sequence number; the content is the content indicated by the data recorded in the corresponding sequence number, and the type is the type of the stored data. E.g. sequence number 1, occupies bytes 1 and 2, byte length 2, the selected data type is short type, and the indicated content is data record block size, e.g. 2048. It should be noted that a short type is a kind of integer variable family defined, and represents a variable i defining a short integer. Type Int4 represents the basic integer, the type specifier is Int, and it takes 4 bytes in memory. The float type is a floating point type, which is one of basic data types and represents a single precision floating point number.
It should be noted that, the node device organizes the seismic data according to a preset protocol format, and in the formed seismic data blocks, one data block is a transmission unit, and one transmission unit is composed of n data packets. If a data block is 2048 in size and is packed in 1000 bytes, it is divided into three data packets, the first two data packets are 1000 bytes each, and the third data packet is 48 bytes. And the node instrument performs acquisition, organizes in real time to form data blocks, and transmits the data blocks to the server in a sub-packet mode.
The seismic data acquired by defining the block heads according to the data structure can be organized according to a certain rule, namely the seismic data can be arranged regularly, so that the client can better identify the seismic data, the loss of seismic data blocks in the transmission process can be reduced, the error rate is further reduced, and the integrity of real-time transmission of the seismic data can be better guaranteed.
In one embodiment, the server is configured to perform message parsing after receiving a first data packet of the seismic data block reported by the node device, extract length values of first two bytes to determine a byte length chunksize (block size) of the entire seismic data block, then continue to wait for the received data to reach the chunk length, perform deserialization on the chunksize bytes into the seismic data block, and obtain the seismic data block sent by the node device. Specifically, the node device organizes the seismic data according to a preset protocol format, and one data block is a transmission unit and one transmission unit consists of n data packets in the formed seismic data blocks. If a data block is 2048 in size and is packed in 1000 bytes, it is divided into three data packets, the first two data packets are 1000 bytes each, and the third data packet is 48 bytes. And the first two bytes in the data packet represent the size of the data record block, so the length value of the first two bytes is extracted by extraction to determine the chunk size of the byte length of the entire seismic data block. And then, waiting for the received data to reach the length of chunksize bytes to indicate that the received seismic data block is completed, wherein in the embodiment, the size of the data block is 2048 bytes, and each data packet is divided into 3 data packets capable of accommodating 1000 bytes, so that the data block is divided into three data packets, and after the three data packets are received, performing deserialization on the chunksize bytes into the seismic data block so that the server receives the completed seismic data block.
