[0024] As mentioned before, with the development of the Internet of Things, the application of Internet of Things control technology in various industries is gradually deepened. Field devices transmit information to the integrated monitoring platform through the IoT gateway, so that the integrated monitoring platform can monitor the field devices. In the rail transit industry, the BAS of the rail transit station transmits data to the air conditioning, ventilation, water supply and drainage, lighting, elevator, escalator and other field devices in the rail transit station and the interval tunnel through the IoT gateway for data monitoring, operation management and control. Therefore, it is necessary to configure the data communication protocol between the BAS and the IoT gateway, and the data communication protocol between the IoT gateway and the field devices.

[0025] Currently, the data communication between the BAS and the IoT gateway is established by manual operation. First, the basic hardware parameters of the Internet of Things gateway, such as Internet Protocol (IP) address, device name, slave address and data acquisition channel, are manually initialized and configured. Then, the data and protocols required by each channel of the IoT gateway are configured in turn, such as configuring Modbus protocol to collect serial port or network port data.

[0026] After configuring the data and protocols required by each channel of the IoT gateway, the original data obtained by each IoT gateway channel is usually manually rearranged and processed in the configuration software of each manufacturer's IoT gateway to obtain the device data collected by each channel and the diagnostic information of the current connection state of each device channel. Then, the data is mapped to the internal data address of the gateway, the data length of each IoT gateway exchanged with the BAS is determined, and finally the IO communication configuration file of each IoT gateway is exported or the server data source is generated in the internal IoT gateway, such as generating a data source based on Modbus, TCPIP and OPC protocols for the BAS to access.

[0027] The BAS can first import the IO configuration file of each IoT gateway, and define the data length of the input and output of each gateway IO configuration file in the BAS according to the data length of the mapped internal data address area, so as to obtain the data of the IoT gateway. Alternatively, the BAS platform defines the start address, data length and protocol of the data read / write of each IoT gateway through separate programming or configuration and the communication program of each IoT gateway to obtain the device information of the mapped internal data address area of the IoT gateway. After the BAS obtains the data of each IoT gateway, the monitoring data, control data and diagnostic information of each IoT gateway are separated from the obtained data. When the single IoT gateway debugging is completed, the above process is performed on all IoT gateways in the station to complete the connection between the BAS and all IoT gateways in the field.

[0028] As can be seen from the above, for the connection between the BAS and each IoT gateway, the field engineer usually needs to perform a large amount of configuration / programming debugging work in the IoT gateway and the BAS. The IoT gateway side needs to define the data acquisition information of each channel in the gateway configuration software, and after acquiring the data, the address rearrangement and mapping of the data to be uploaded are manually performed. The BAS side needs to configure the IO configuration file of each IoT gateway, or realize communication through programming.

[0029] However, since the number of rail transit stations is large, and a large number of IoT gateways and field devices are arranged in a rail transit station, the manual labor intensity is large and the time consumed is large when the communication is established manually, so that the efficiency of the communication establishment process is low.

[0030] In the embodiment of the present application, the first configuration file and the second configuration file are generated according to the input parameter information, then the data acquisition port of the Internet of Things gateway is initialized and the first data storage area is generated according to the first configuration file, and the second configuration file is sent to the management end device, so that the management end device generates the second data storage area. Thus, the data synchronization between the first data storage area and the second data storage area can be realized to realize the data synchronization between the management end device and the Internet of Things gateway. Since the first configuration file and the second configuration file are automatically generated according to the input parameters, and the subsequent process is automatically performed according to the first configuration file and the second configuration file, the communication between the Internet of Things gateway and the management end device does not need to be established manually, and the communication between the Internet of Things gateway and the field device does not need to be established manually, thereby reducing the manual labor intensity and improving the efficiency of the communication establishment process.

[0031] The communication establishment method, device and electronic equipment provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0032] Figure 1is a flow chart of a communication establishment method 100 provided by an embodiment of the present application. As shown in Figure 1 The communication establishment method 100 is used for an Internet of Things gateway, and the communication establishment method 100 comprises the following steps.

[0033] In step 101, a first configuration file and a second configuration file are generated according to input parameter information.

[0034] The first configuration file and the second configuration file are generated according to the input parameter information. The parameter information can be input by a person from a graphical user interface. Optionally, the input parameter information can comprise parameters required for configuring a communication serial port, such as enable En, baud rate Baud, data bit Data_Bit, stop bit Stop_Bit, and check mode Pair. The input parameter information can also comprise communication parameters between the Internet of Things gateway and a field device, such as address S_ID, function code Fun_Code, start address addr, data length length, and cycle time Cycle_time. The input parameter information can also comprise communication parameters between the Internet of Things gateway and a management end device (for example, a PLC), such as PLC_Type, communication port number Port, PLC IP, PLC rack number Rack, slot number Slot, field data storage DB block number, and TCP server monitoring port.

[0035] It should be understood that the above parameters are only used as an example for illustration, and should not limit the embodiments of the present application. The specific input parameter settings can be set according to the types of the Internet of Things gateway, the field device, and the management end device, as well as the communication mode and the communication protocol between different devices.

[0036] The first configuration file and the second configuration file are generated according to the input parameter information. Exemplarily, the first configuration file can be used to configure the communication connection between the Internet of Things gateway and the field device, and the second configuration file can be used to configure the communication between the Internet of Things gateway and the management end device.

[0037] In step 102, the communication connection between the Internet of Things gateway and the field device is configured according to the first configuration file.

[0038] The communication connection between the Internet of Things gateway and the field device is configured according to various parameters included in the first configuration file. The data acquisition port is initialized. Exemplarily, the communication serial port can be used for communication between the IOT gateway and the field device. The communication serial port can be initialized according to the enable En, baud rate Baud, data bit Data_Bit, stop bit Stop_Bit, and check mode Pair included in the first configuration file, so as to enable the communication between the IOT gateway and the field device.

[0039] Step 103, generating the first data storage area according to the command sequence included in the first configuration file.

[0040] The command sequence included in the first configuration file is generated according to the input parameter, and the command sequence includes at least one read-write command, the read-write command can perform read-write operation on the field device through the data acquisition port, and the first data storage area can store read-write data and command state feedback information corresponding to the command sequence.

[0041] In an example, the command sequence can be a Modbus RTU command, and in the first configuration file, a slave address, a command type, a start address, a data quantity, and the like can be included. The slave address is the address of the field device, the command type is the task to be executed, for example, a read task, a write task, and the like, the start address is the start position of the read-write data, and the data quantity is the quantity of data to be read or written. Thus, the data can be read or written from the field device through the command sequence included in the first configuration file.

[0042] The command state feedback information is the completion of the read-write command in the command sequence, for example, when the read-write command in the command sequence is successfully executed, the command state feedback information is that the command is executed successfully, and when the read-write command in the command sequence is not successfully executed, the command state feedback information is that the command is executed unsuccessfully, and the like.

[0043] The first data storage area can be generated according to the command sequence included in the first configuration file, and the storage length of the first data storage area can be the length sum of the data read from the field device, the data to be written into the field device, and the command state feedback information according to the read-write command in the command sequence. For example, the length of the first data storage area can be equal to the sum of the length of the data read from the field device, the length of the data to be written into the field device, and the number of read-write commands, that is, the read data, the data to be written, and the command state feedback information can be stored. It should be understood that the read data and the data to be written into the field device can be stored in the first data storage area in the form of an array, or the read data and the data to be written into the field device can be stored in the first data storage area in the form of a storage register address, or other storage manners can be used, which are not limited in the embodiments of the present application.

[0044] Step 104, sending the second configuration file to the management end device, so that the management end device generates a second data storage area with a structure matched with the first data storage area according to the second configuration file, and synchronizes the first data storage area with the second data storage area.

[0045] The second configuration file is sent to a management terminal device, which can be a PLC, a PC or other device with a control function. After receiving the second configuration file, the management terminal device generates a second data storage area matching the first data storage area. The second data storage area can store data with the same length as the first data storage area. The first data storage area and the second data storage area can exchange data to achieve data synchronization.

[0046] In an example, the input parameters include parameters for communication between the management terminal device and the IoT gateway, such as PLC_Type, Port, PLCIP, Rack, Slot, DB block number, TCP server monitoring port, and other information. The first configuration file includes communication instructions for communication between the management terminal device and the IoT gateway generated according to the above parameters. Thus, the first data storage area and the second data storage area can exchange data to achieve data synchronization.

[0047] In the embodiments of the present application, the first configuration file and the second configuration file are generated according to the input parameter information. Then, the IoT gateway is initialized for data collection port and the first data storage area is generated according to the first configuration file. The second configuration file is sent to the management terminal device to make the management terminal device generate the second data storage area. Thus, the first data storage area and the second data storage area can synchronize data to achieve data synchronization between the management terminal device and the IoT gateway. Since the first configuration file and the second configuration file are automatically generated according to the input parameters, and the subsequent process is automatically performed according to the first configuration file and the second configuration file, it is not necessary to manually establish communication between the IoT gateway and the management terminal device, and it is not necessary to manually establish communication between the IoT gateway and the field device. This reduces the labor intensity and improves the efficiency of the communication establishment process.

[0048] In a possible implementation, the first data storage area includes a first sub-data storage area and a second sub-data storage area. The first sub-data storage area can store first data, wherein the first data includes data written to the field device by the write command in the command sequence. The second sub-data storage area can store second data, wherein the second data includes data read from the field device by the read command in the command sequence, command state feedback information of the write command, and command state feedback information of the read command.

[0049] The first data storage area includes a first sub-data storage area and a second sub-data storage area, the first sub-data storage area is used to store data to be written into the field device, the data to be written into the field device can be control data, etc., the management end device synchronizes the data to be written into the field device from the second data storage area to the first sub-data storage area in the first data storage area, and then the Internet of Things gateway can write the data stored in the first sub-data storage area into the field device.

[0050] The second sub-data storage area stores data read from the field device, command state feedback information of a write command, and command state feedback information of a read command, and the management end device can realize reading data and reading state feedback information of each read-write command in the read-write command sequence according to the data stored in the second sub-data storage area synchronized to the second data storage area.

[0051] In the embodiment of the present application, the first data storage area includes a first sub-data storage area and a second sub-data storage area, so that the read-write data can be separated, and when the data in the second data storage area in the management end device and the first data storage area is synchronized, the data written into the field device by the management end device can be stored in the first sub-data storage area, and the data of the field device to be read by the management end device can be stored in the second sub-data storage area, thereby improving the efficiency of data synchronization between the first data storage area and the second data storage area.

[0052] In a possible implementation, when the first data storage area and the second data storage area are synchronized, the data length of the first data and the second data can be determined, then the first data and the second data are packaged according to the data length of the first data and the second data and the communication protocol between the Internet of Things gateway and the management end device, M data packets are obtained, wherein M is a positive integer greater than or equal to 2, and the M data packets are synchronized between the first data storage area and the second data storage area through the communication protocol.

[0053] The data length of the first data and the second data is determined, the data length of the first data can be obtained by adding the length of the write register of the data to be written into the field device, and the length of the second data can be obtained by adding the length of the read register of the data read from the field device and the number of read-write commands in the command sequence. It should be understood that since each read-write command corresponds to a command state feedback information, the length of the command state feedback information is equal to the number of read-write commands.

[0054] After the data length of the first data and the second data is determined, the first data and the second data are packetized according to a communication protocol between the Internet of Things gateway and the management terminal device, M data packets are obtained, and the M data packets are synchronized between the first data storage area and the second data storage area through the communication protocol.

[0055] It should be understood that the process of synchronizing the M data packets between the first data storage area and the second data storage area is that the management terminal device synchronizes each data packet included in the first data stored in the second data storage area to the first data storage area of the Internet of Things gateway, and the Internet of Things gateway synchronizes each data packet included in the second data stored in the first data storage area to the second data storage area of the management terminal device. Thus, the read and write of the management terminal device to the Internet of Things gateway are realized.

[0056] In the embodiments of the present application, the data length of the first data and the second data is determined first, then the first data and the second data are packetized according to the communication protocol and the data length, M data packets are obtained, and the M data packets are synchronized between the first data storage area and the second data storage area. Thus, the read and write operation of the management terminal device to the Internet of Things gateway is realized, the data synchronization is realized, and since the first data and the second data are packetized according to the communication protocol, the complete transmission of the first data and the second data is ensured, and the incomplete transmission of the first data and the second data due to the protocol limiting the data length is avoided.

[0057] In a possible implementation, when the first data and the second data are packetized according to the data length of the first data, the data length of the second data, and the data length threshold of the transmission protocol, and M third data are obtained, if the data length of the first data is less than or equal to the data length threshold defined by the communication protocol, the first data is divided into one data packet; if the data length of the first data is greater than the data length threshold, the first data is divided into m data packets, where m is a positive integer greater than or equal to 2, the data length of the 1st to the m-1th data packets in the m data packets is equal to the data length threshold, and the data length of the mth data packet in the m data packets is less than or equal to the data length threshold.

[0058] If the data length of the second data is less than or equal to the data length threshold, the second data is divided into one data packet; if the data length of the second data is greater than the data length threshold, the second data is divided into n data packets, where n is a positive integer greater than or equal to 2, the data length of the 1st to the n-1th data packets in the n data packets is equal to the data length threshold, the data length of the nth data packet in the n data packets is less than or equal to the data length threshold, and M = m + n.

[0059] It should be understood that the data length of the mth data packet in the m data packets of the first data split is L1-(m-1)*x, where L1 is used to represent the data length of the first data, and x is used to represent the data length threshold, and the data length of the nth data packet in the n data packets of the second data split is L2-(n-1)*x, where L2 is used to represent the data length of the second data, and x is used to represent the data length threshold.

[0060] In the embodiments of the present application, the first data and the second data are packetized according to the communication protocol and the data length, and M data packets are obtained, so that the management end device can perform read and write operations on the Internet of Things gateway, data synchronization is achieved, and because the first data is split into 1 or m data packets and the second data is split into 1 or n data packets according to the communication protocol, the complete transmission of the first data and the second data is ensured, and incomplete transmission of the first data and the second data due to protocol-limited data length is avoided.

[0061] In a possible implementation, the third data storage area and the fourth data storage area are generated according to the command sequence, the third data storage area is used to store the first write data that needs to be written to the field device, and the fourth data storage area is used to store the read data read from the field device and the command state feedback information of the command sequence; the data stored in the third data storage area and the fourth data storage area is sorted and processed according to the data type; and the first write data, the read data and the command state feedback information after the sorting processing are written to the first data storage area.

[0062] According to the command sequence included in the first configuration file, the third data storage area and the fourth data storage area are generated, the third data storage area can store the first write data that needs to be written to the field device, the first write data can include the slave address, the start address and the write data area of each write command, and the fourth data storage area can store the first read data read from the field device, the first read data can include the slave address, the start address, the command length and the like of each read command.

[0063] The data stored in the third data storage area and the fourth data storage area is sorted and pre-processed, and the data stored in the third data storage area and the fourth data storage area after the sorting is stored to the first data storage area.

[0064] In the embodiments of the present application, the third data storage area and the fourth data storage area are generated according to the command sequence in the first configuration file, so that the first write data that needs to be written to the field device can be stored, and the first read data read from the field device and the command state feedback information of each read and write data can be stored.

[0065] In a possible implementation, when sorting the data stored in the third data storage area and the fourth data storage area according to the data type, the write command state feedback information corresponding to the write command can be filtered from the command state feedback information stored in the fourth data storage area, and then the read data corresponding to the same read command and the command state feedback information in the fourth data storage area are combined to obtain at least one data pair, wherein the data pair includes the read data corresponding to the same read command and the command state feedback information, and the data stored in the third data storage area and the fourth data storage area are sorted in the order of the first write-in data, the write command state feedback information, and the data pair.

[0066] The command state feedback information corresponding to the write command is separated from the fourth data storage area, and then the read data of the field device read by each read command and the command state feedback information corresponding to the read command are separated from the fourth data storage area, and are determined as a data pair, and are sorted in the order of the first write-in data, the write command state feedback information, and the data pair. Specifically, the order is the first write-in data, the write command state feedback information, the read data 1 corresponding to the read command 1, the state feedback information of the read command 1, the read data 2 corresponding to the read command 2, the state feedback information of the read command 2, the read data 3 corresponding to the read command 3, the state feedback information of the read command 3, and so on.

[0067] In an example, the sorted first write-in data can be stored as first data to the first sub-data storage area, and the sorted write command state feedback information and data pair can be stored as second data to the second sub-data storage area, thereby realizing the storage of the sorted data stored in the third storage area and the fourth storage area to the first data storage area.

[0068] In the embodiment of the present application, the data stored in the third data storage area and the fourth data storage area is sorted in the order of the first write-in data, the write command state feedback information, and the data pair, thereby realizing the storage of the read-write separated data stored in the third data storage area and the fourth data storage area to the first data storage area, and improving the efficiency of data synchronization.

[0069] In a possible implementation, the data comparison area can be generated according to the command sequence, wherein the data comparison area is used to store the second write-in data which only changes the write command to write the field device, and then the second write-in data is compared with the first write-in data. If the second write-in data is different from the first write-in data, the second write-in data is determined as the first write-in data and is stored in the third data storage area.

[0070] The data comparison area can be generated according to the command sequence in the first configuration file, the data comparison area and the third data storage area are matched, that is, the data lengths are consistent, the data comparison area can store second write data, the second write data is data that needs to be written to the field device, when the second write data is received, the second write data can be compared with the first write data stored in the third data storage area, at this time, if the second write data and the first write data are inconsistent, the second write data is stored as the first write data in the third data storage area, and a write command is executed, if the second write data and the first write data are consistent, the write data stored in the third data storage area is not changed, and the write command is not executed, that is, the write command is only executed when the data is changed.

[0071] Optionally, the data comparison area is generated only when the command for writing data only when the data is changed is included in the first configuration file, and the data comparison area is not generated when only the command for writing constant data is included in the first configuration file.

[0072] In the embodiment of the application, the data comparison area is generated according to the command sequence, and the second write data stored in the data comparison area is compared with the first write data stored in the third data storage area, so that the write data operation only when the data is changed can be realized, and the efficiency of writing data from the Internet of Things gateway to the field device and / or writing data from the management end device to the Internet of Things gateway is improved.
