After receiving the registration packet, the internet of things platform firstly analyzes according to a protocol containing a registration flow, if the analysis is successful, the equipment protocol, the IP address and the port are stored in a database, after the access information is stored, the internet of things platform sends request packets for obtaining the equipment state and the equipment information to the IP and the port of the access information in sequence according to the supported protocol, and waits for equipment response. The acquisition modes of each protocol are different, so that the device directly ignores or replies error information if receiving the requests of different protocols, and when the information of the internet of things platform is received overtime or information which is sent by the device and does not conform to the expected format is received, the device is considered not to support the protocol of the attempt, and the next round of attempt is started.

if the equipment sends reply data to any one of the four pieces of information, the Internet of things platform analyzes the reply data, if the data accords with CRC16 verification and the reply data accords with address bit analysis, the equipment is considered to belong to a modbus protocol, protocol information is stored in a database, and if no return information is received or format verification of the return information fails, other protocol attempts are carried out.
In a preferred embodiment of the present invention, in response to unsuccessful parsing of a registration packet sent by a device by an internet of things platform, sending specified data to the device according to a preset sequence at intervals of a preset time includes:
and in response to the fact that the internet of things platform fails to analyze the registration packet sent by the device, sending first designated data 010100000001 FD CA, second designated data 010200000001B 9 CA, third designated data 010300000001840A and fourth designated data 01040000000131 CA to the device in sequence, wherein the interval for sending the designated data is 5 seconds.
In a preferred embodiment of the present invention, further comprising:
responding to unsuccessful analysis of the registration packet sent by the Internet of things platform to the equipment, and sending data 6801000000000068110433333D 33 BC 16 to the equipment;
in response to the device sending the reply data, determining whether the reply data begins at 68 and is different from the sent data and conforms to the CS sum check;
in response to the reply data beginning at 68 and being different from the sent data and conforming to the CS and checksum, determining that the protocol for the device to interface with the internet of things is the DLT645 protocol. If the internet of things platform fails to analyze the registration packet sent by the equipment, entering a stage of sending an identification instruction by the platform, and sending data to the equipment: 6801000000000068110433333D 33 BC 16, if the device replies with data beginning with 68 and different from the data sent and conforming to the CS sum check, then the device is considered to belong to the DLT645 protocol and the protocol is saved.
In a preferred embodiment of the present invention, the method further comprises:
and in response to the fact that the Internet of things platform fails to analyze the registration packet sent by the equipment and the fact that the protocol for docking with the Internet of things fails, repeatedly executing the process for 2 to 3 times.
In the communication flow with the equipment, each protocol is tried only once, and if the network connection error exists, the supported protocols still fail to be matched, so that the communication flow can be repeated for 2-3 times, and the communication stability is improved.
The communication flow only comprises common communication protocols in the market, and some cold protocols are not contained in the communication flow, so that in a preferred embodiment, the protocol can be expanded, the capabilities of the supported devices and the Internet of things platform are expanded, and more devices are supported for identification. At present, most manufacturers support active registration of devices, but except for a protocol for specifying registration content, the registration information of the devices of many manufacturers is different. Therefore, the registration packets are not matched in the scheme except for the GB28181 protocol and the MQTT protocol. If the registration packet of the device supports customization, the registration packet may be set according to the following format, and the data is 16-ary: 6B 00 XX 0X XX XX, wherein the first byte 6B 00 is a fixed message header, the second byte high 8 bit XX represents a docking protocol 01 to represent a modbus protocol, 02 represents a DLT645 protocol, 03 represents an OPC UA protocol, the second byte low 8 bit represents a data acquisition mode, 01 represents that the equipment is actively requested by an Internet of things platform, 02 represents that the equipment is actively pushed to the Internet of things platform, and the third byte is CRC16 check.
After receiving the registration packet, the server preferentially matches the GB28181 protocol with the MQTT protocol according to the original logic, after the matching fails, the server analyzes according to the predefined format, and after the analysis succeeds, the server can directly acquire the docking protocol of the equipment without the step of sending an identification instruction by a platform, so that the identification speed is increased, and the network pressure is reduced.
At present, the detailed communication flow of the scheme only comprises GB28181, MQTT, modbus and DLT645 protocols, although the protocols comprise higher-occupation docking protocols in the market, the internet of things docking protocols are more, and more novel protocols or existing protocols occupy more markets along with the development of the times. Therefore, the communication flow in the scheme can be expanded, other protocol analysis flows are added, and analysis and judgment are carried out in sequence. In a preferred embodiment, more protocols, such as OPC UA protocol, etc., may be supported, and the manner of determination thereof is added after the detailed communication flow. When the internet of things platform identifies the protocol, the protocol is analyzed only once, and if the protocol is not supported completely by the equipment due to network reasons, the identification is wrong, so that in the preferred embodiment, more identification data can be sent to the equipment, and the judgment is more complete. In the above embodiment, the basic information of each protocol is sent only once, and due to network fluctuation, device power failure, and other reasons, return information may be lost, which may result in failure of protocol determination. Therefore, in a preferred embodiment, a retry mechanism can be established, wherein the protocol identification is performed on the device once every 5 minutes, the identification is not performed again after the identification is successful, and the retry is performed after the identification is failed. Considering the factors such as bandwidth pressure, the user can set the retry interval and the maximum retry number to ensure the normal operation of the system.
In a preferred embodiment, the detailed communication flow of the device analyzes different communication protocols in sequence, but the difference between different protocols is large, and the analysis sequence can be disturbed to form a new scheme.
In a preferred embodiment, the information content registered by the device is fixed content, a first byte is fixed, a second byte represents the protocol content, and the definition can be modified, for example, the first two bytes are fixed, and a third byte represents the protocol information.
In the scheme, the communication with the equipment uses TCP and UDP according to different protocols, but in practice, the equipment uses other protocols for communication, and the communication protocol in the scheme can be replaced by other protocols.
Through the technical scheme of the invention, the equipment can be automatically registered to the platform of the Internet of things and the equipment protocol is displayed without manual configuration.
It should be noted that, as can be understood by those skilled in the art, all or part of the processes in the methods of the embodiments described above can be implemented by instructing relevant hardware by a computer program, and the program may be stored in a computer-readable storage medium, and when executed, the program may include the processes of the embodiments of the methods described above.
