102. setting a corresponding communication protocol, a baud rate and a check bit in the gateway according to the configured communication address, the baud rate and the check bit of the burner;
103. and setting equipment data and collecting information of the boiler burner.
Based on the content of the foregoing method embodiment, as an alternative embodiment, in the method for collecting information of a boiler burner provided in the embodiment of the present invention, the first interface includes an RJ45 interface; the second interface comprises a DB9 serial port.
Based on the content of the above method embodiment, as an alternative embodiment, in the method for collecting information of a boiler combustor provided in the embodiment of the present invention, the first combustor information includes an RS232 signal; the second burner information includes an RS485 signal.
Based on the content of the foregoing method embodiment, as an alternative embodiment, in the method for collecting information of a boiler combustor provided in an embodiment of the present invention, the device data includes: I/O drivers for devices, channels, device IDs, and device tag points.
Specifically, an RS232/RS485 converter is adopted to convert the collected RS232 signals into RS485 differential signals, so that a plurality of devices can be networked for communication. The DB9 interface RS232 signal of each combustor panel is respectively accessed into the converter and converted into RS485 signal, then a plurality of gateways (namely acquisition gateways, different from the RS232/RS485 converter) which are connected in series and then connected with the MODBUS TCP protocol support are connected, different communication addresses are set on a plurality of combustors before communication, and the same baud rate check bit is configured. A corresponding communication protocol MODBUS RTU, a baud rate and a check bit consistent with actual communication equipment are arranged in the gateway, and an RS232/RS485 converter adopts MOXA MGate MB 3480. Next, the corresponding I/O drivers and channels (i.e., channels), DeviceID (i.e., device ID), and Tag (i.e., device Tag points) are configured using KEPWARE OPC SERVER or other OPC software.

The serial port communication signal is an RS232 level signal and can only carry out one-to-one serial port communication. If the signals are not converted into RS485 differential signals, seven combustors need to occupy two gateways of the four-port DB9, and the industrial control network resources of the centralized control system are occupied greatly. The RS232/485 signals are converted into RS485 signals after being converted, 7 burner serial ports can be connected in series, only one DB9 interface of one gateway is needed, and the gateway cost and the network burden are saved.

The centralized control SERVER can configure the drive and address of the gateway and the address of the register needing to be read and written by software supporting OPC SERVER such as KEPserverEX or IGS, and can acquire and control the data of the corresponding combustor in a timing manner. The main information obtained is the load and flame intensity signals of the burner. Among them, Modbus is the most common open communication protocol in the industrial field; MOXA is masha corporation, taiwan, an industrial communication equipment manufacturer; OPC establishes a unified data access specification between various communication protocols and application programs of respective automation manufacturers, effectively separates hardware and application software, mainly solves the problem of data exchange between a process control system and its data source, and can provide transparent data access between applications. The OPC SERVER can be used as a SERVER to provide real-time industrial control exchange information for a plurality of clients.

The burner control panel can be seen in fig. 5. In fig. 5, the RJ45 interface is converted to a serial port of the general DB 9. The method is characterized in that a super-five twisted-pair cable is used for leading out three wires (the other 5 wire cores are cut off and are not connected) of a first pin, a third pin and a fourth pin from an RJ45 interface (essentially a crystal head plug), is inserted into a COM2 interface of a burner operation panel, respectively corresponds to TxD, RxD and GND signals of an RS232 electrical standard, and is connected to a second interface, a third interface and a fifth interface of a DB9 interface (RS 232 end), and the conversion of a physical interface of a serial signal from RJ45 to a general DB9 is completed.
