Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a data transmission method, where the data transmission method is applied to a data transmission system, the data transmission system includes an anemometer tower, a data transmission unit DTU, and an acquisition server, and the data transmission method includes:
step S100, controlling the anemometer tower to transmit target data stored in the anemometer tower to the data transmission unit DTU according to a first preset protocol;
specifically, the Data transmission method provided in this embodiment is applied to a Data transmission system including a wind measuring tower, a wireless Data transmission module and a collection server, where the wireless Data transmission module includes a DTU (Data Transfer unit) in this embodiment, the wind measuring tower is used to collect wind energy resource-related Data, that is, target Data in this embodiment, and the wind measuring tower is also used to store the target Data. The data transmission system in this embodiment performs data transmission through a Modbus protocol (a serial communication protocol), where serial communication is performed between the anemometer tower and the data transmission unit DTU through a Modbus-RTU protocol or a Modbus-ACSII protocol, a first preset protocol in this embodiment is the Modbus-RTU protocol or the Modbus-ACSII protocol, except that the Modbus-RTU samples hexadecimal representation data, and the Modbus-ASCII uses ASCII codes to represent data. And according to a first preset protocol, the data transmission system controls the anemometer tower and transmits the target data stored in the anemometer tower to the DTU.
Step S200, converting the target data into a network data packet through the data transmission unit DTU;
specifically, the data transmission unit DTU in this embodiment is a wireless terminal device that is specially used to convert serial data (i.e., target data in this embodiment) into IP (Internet Protocol, network layer Protocol) data (i.e., a network data packet in this embodiment), or convert a network data packet into target data and transmit the target data through a wireless communication network. The most basic usage of the data transmission unit DTU is: a Subscriber Identity Module (SIM) card with a General Packet Radio Service (GPRS) function is put into a Data Transmission Unit (DTU), and after the DTU is powered on, the DTU is firstly registered in a GPRS network and then establishes socket connection with a data processing center through the GPRS network. The data transmission unit DTU is a client connected with the socket, and the data processing center is a server connected with the socket. The socket is connected to a part of a TCP (Transmission Control Protocol) Protocol and a UDP (User Datagram Protocol) Protocol, the data Transmission unit DTU and the data processing center use the same Protocol, and after an IP address and a port number of the data processing center are configured for the data Transmission unit DTU, the data Transmission unit DTU is connected to a device of a User through a serial port. For example, after being powered on, the data transmission unit DTU first registers to a mobile network, then sends a request packet for establishing socket connection to the mobile, the mobile sends the request to the internet, and server software of the data processing center establishes connection after receiving the request, and sends response information. The request information sent by the data transmission unit DTU is a data packet on the Internet, and the socket connection can be established to realize two-way communication.
Step S300, according to a second preset protocol, controlling the data transmission unit DTU to transmit the network data packet to the acquisition server.
Specifically, in this embodiment, the data transmission unit DTU and the acquisition server perform wireless communication via a Modbus-TCP protocol (i.e., a second preset protocol in this embodiment), and the wireless communication process is as follows: the Modbus equipment is divided into a master station and a slave station. The number of the master stations is only one, and the number of the slave stations can be multiple. When TCP communication is used, the master station is a client and actively establishes connection with the slave station; the slave station is a server and waits for the connection sent by the master station. The Data frame of the Modbus-TCP may be divided into two parts, namely, a Modbus Application Protocol (MBAP) + Protocol Data Unit (PDU), where PDU = function code + Data field, and the length of the Data field is not fixed, and is determined by a specific function. MBAP is a message header, the length is 7 bytes, and the components are as follows: transaction identification, protocol identification, length and unit identifier, wherein the transaction identification is a serial number of the message, and 1 is added after each communication to distinguish different communication data messages; the protocol mark 00 represents a Modbus-TCP protocol; the length is the data length and the unit is byte; the unit identifier may be understood as a device address. The Modbus has four operation targets: the functional code comprises a coil, a discrete input register, a holding register and an input register, wherein a functional code 01 is in a coil reading state, a functional code 02 is in a discrete input reading state, a functional code 03 is in a holding register reading state, and a functional code 04 is in an input register reading state.
According to the embodiment, the wind measuring tower is controlled, the target data stored in the wind measuring tower are transmitted to the data transmission unit DTU according to the first preset protocol, the target data are converted into the network data packet in the data transmission unit DTU, finally, the data transmission unit DTU is controlled to transmit the network data packet to the acquisition server according to the second preset protocol, wireless transmission of the wind measuring data stored in the wind measuring tower is achieved through the data transmission system, the first preset protocol and the second preset protocol, and the transmission cost of the wind measuring data is reduced.
In an embodiment, the data transmission system further includes a mobile communication node, and the data transmission method provided in the embodiment of the present application may further include:
step S10, establishing serial port connection between the anemometer tower and the data transmission unit DTU;
step S20, establishing the connection between the data transmission unit DTU and the socket of the mobile communication node;
and step S30, establishing network connection between the mobile communication node and the acquisition server.
Specifically, before data transmission is performed on target data, the data transmission system needs to establish connection between each node, and it is understood that the data transmission system further includes a mobile communication node located between the data transmission unit DTU and the acquisition server. The wind measuring tower is connected with the data transmission unit DTU through a wired serial port, the data transmission unit DTU is connected with the mobile communication node through a socket, the mobile communication node is connected with the acquisition server through a network, and the process of the connection is described by taking the socket connection as an example in the embodiment: before a socket connection is opened, a socket needs to be created, and then the IP and the port of the socket are appointed; the server side starts monitoring and waits for the access of the client side; the client is connected with the server, the server receives the client connection, and three times of handshaking are carried out in the connection process; the client and the server send and receive data, and the operating system completes the steps of data confirmation, data retransmission and the like; by closing the connection, the operating system may perform four hand swings.
In the embodiment, before the data transmission system transmits the target data, the corresponding connection between the nodes is established, and a transmission network is established for the anemometry data.
In an embodiment, the data transmission method provided in the embodiment of the present application may further include:
step S21, registering the DTU to a mobile communication network corresponding to the mobile communication node;
step S22, sending the target internet protocol address allocated by the mobile communication node and the fixed internet protocol address of the mobile communication node to the data transmission unit DTU through the mobile communication network;
and step S23, establishing the connection between the DTU and the socket of the mobile communication node according to the target IP address and the fixed IP address.
Specifically, after the data transmission unit DTU is powered on, it registers in the GPRS network (i.e., the Mobile communication network corresponding to the Mobile communication node in this embodiment) first, reads out the working parameters (including GPRS dialing parameters, serial baud rate, IP address, and the like) stored in the internal flash memory of the data transmission unit DTU, where the working parameters are configured in advance, and the data transmission unit DTU logs in a GSM (Global System for Mobile Communications) network and then performs GPRS dialing. After successful dialing, the data transmission unit DTU will obtain a randomly allocated internal IP address (i.e. the target IP address in this embodiment). That is, the data transmission unit DTU is located in the mobile communication network intranet, and the IP address of the mobile communication network intranet is usually not fixed and changes with each dialing. The data transmission unit DTU actively initiates a communication connection with the data processing center (i.e., the mobile communication node in this embodiment) and keeps the communication connection existing all the time. The DTU is positioned in the mobile communication network intranet, and the IP address is not fixed. Thus, the data transmission unit DTU can be actively connected to the data processing center only, and not to the data processing center. This requires that the data processing center have a fixed public IP address (i.e., a fixed internet protocol address in this embodiment) or a fixed domain name. The public network IP address or the fixed domain name of the data processing center is stored in the data transmission unit DTU as a parameter, so that the data transmission unit DTU can be actively connected to the data processing center once the power-on dialing is successful, and the socket connection between the data transmission unit DTU and the mobile communication node is established.
In the embodiment, through mobile communication network registration, internet protocol address allocation and transmission, a socket connection between the DTU and the mobile communication node is established, and a transmission network is established for the anemometry data.
In an embodiment, the data transmission method provided in the embodiment of the present application may further include:
step S110, sending a first data frame corresponding to a first preset protocol to the anemometer tower through the serial port connection;
and step S120, under the condition that the anemometer tower responds to the first data frame, controlling the anemometer tower to transmit target data corresponding to the first data frame stored in the anemometer tower to the data transmission unit DTU.
Specifically, the anemometer tower is connected with the data transmission unit DTU in a serial port manner, in a Modbus-RTU protocol, the data transmission unit DTU is a master, the anemometer tower is a slave, and the master sends a Modbus message to the slave, where the Modbus message is a frame of data sent by the master to the slave, and the Modbus message includes an address of the slave, an operation to be executed by the master, a check code and other contents, specifically including a slave address, a function code, data and a check code. Each slave has a unique address, the slave address occupies one byte, the range is 0-255, the effective range is 1-247, and 255 is a broadcast address (the broadcast is to send responses to all the slaves); the function code occupies one byte, and the operation objects of the Modbus include four types: the system comprises a coil, a discrete input register, a holding register and an input register, wherein a function code 01 is in a coil reading state, a function code 02 is in a discrete input reading state, a function code 03 is in a holding register, and a function code 04 is in an input register reading state; different function codes have different functions, such as inquiring data of a slave, wherein the data refers to the address of the data to be inquired, the number of bytes to be inquired and the like; errors may occur during data transmission, and whether the received data is correct is detected through the check code. And under the condition that the anemometer tower responds to the first data frame, controlling the anemometer tower to transmit target data corresponding to the first data frame stored in the anemometer tower to the data transmission unit DTU.
According to the embodiment, the target data are transmitted through the first preset protocol and the first data frame, so that the transmission of the anemometry data stored in the anemometry tower is realized, and the transmission cost of the anemometry data is reduced.
In an embodiment, the data transmission method provided in the embodiment of the present application may further include:
step S130, under the condition that the first address domain is matched with the anemometer tower and the first data frame is determined to be accurately sent according to the check domain, inquiring the stored data of the anemometer tower according to the first functional domain;
step S140, determining that the anemometer tower responds to the first data frame when the target data corresponding to the first data field exists in the stored data of the anemometer tower.
Specifically, in the Modbus-RTU protocol, the data transmission unit DTU is a master, the anemometer tower is a slave, and the data transmission unit DTU sends a frame of data including an address of the slave (i.e. the first address field in this embodiment), a function code (i.e. the first function field in this embodiment), data (i.e. the first data field in this embodiment) and a check code (i.e. the check field in this embodiment) to the anemometer tower, where the first address field is a unique address owned by each slave, the first address field occupies one byte, and ranges from 0 to 255, the valid range is 1 to 247, and 255 is a broadcast address (broadcast is sending a response to all slaves); the first functional domain occupies one byte, the operation objects of the Modbus comprise four types, namely a coil, a discrete input register, a holding register and an input register, the first functional domain 01 is in a coil reading state, the first functional domain 02 is in a discrete input reading state, the first functional domain 03 is in a holding register, and the first functional domain 04 is in a read-input register and the like; different first function domains have different functions, such as inquiring slave data, and the first data domain refers to the address of the slave data to be inquired, the number of bytes to be inquired and the like; errors may occur during data transmission, and whether the received data is correct is detected through the check field. Therefore, when the first address domain is the address of the anemometer tower and the first data frame is determined to be accurately sent according to the check domain, the stored data of the anemometer tower is inquired through the first functional domain, and when the target data corresponding to the inquired first data domain exists in the stored data of the anemometer tower, the anemometer tower is determined to respond to the first data frame, otherwise, the anemometer tower is determined not to respond to the first data frame.
According to the embodiment, whether the anemometry tower responds to the first data frame or not is determined through the first data frame comprising the first address domain, the first function domain, the first data domain and the verification domain, and the safe and accurate transmission of the anemometry data is guaranteed while the anemometry data transmission network is built.
