For convenience in understanding the device access method of the internet of things platform provided by the application, a hardware application scenario of the device access method is introduced first. Specifically, the equipment access method of the Internet of things platform can be applied to headquarters and branch machine rooms. Using collection layer equipment as DTU equipment for example, as shown in fig. 1, the headquarters machine room includes an exit gateway, a convergence switch, an IOT platform, a POE switch, DTU equipment and a sensor, and the DTU equipment is connected with the corresponding sensor for transmitting data collected by the corresponding sensor to the internet of things platform. The IOT platform is connected with the POE switch through the convergence switch, and the POE switch is connected with the DTU equipment. The POE switch realizes the configuration of the virtual IP address of the DTU equipment and the address of the platform of the Internet of things, realizes the connection of the DTU equipment and the TCP (Transmission Control Protocol, Chinese full name) of the IOT platform, and realizes the access of the DTU equipment to the IOT platform. Branch portion's computer lab includes the export gateway, assembles switch, POE switch, DTU equipment and sensor, and DTU equipment is connected with the sensor that corresponds for data to the sensor collection that the thing networking platform transmission corresponds. The export gateway of headquarter computer lab passes through network connection with the export gateway of branch computer lab, realizes being connected of POE switch in the branch computer lab and the IOT platform in the headquarter computer lab, and then utilizes POE switch configuration DTU equipment's virtual IP address and thing networking platform address in branch computer lab, realizes that the DTU equipment of branch computer lab inserts the IOT platform. The equipment access method of the Internet of things platform can be applied to POE switches in headquarters and branch machine rooms.
The embodiment of the application discloses a device access method of an Internet of things platform, which reduces the deployment workload of acquisition layer devices and saves IP address resources.
Referring to fig. 2, a flowchart of a device access method for a platform of a first internet of things according to an exemplary embodiment is shown, and as shown in fig. 2, the method includes:
s101: establishing communication connection with a target Internet of things platform, and acquiring a target address corresponding to the target Internet of things platform;
the main execution body in this embodiment is a switching device, such as a poe (power Over ethernet) switch, and is to configure an IP address of an acquisition layer device and an address of an internet of things platform, so that the acquisition layer device is accessed to the internet of things platform. The acquisition layer device is used for acquiring information, such as a DTU device, a gateway device, and the like.
In this step, a communication connection is established between the switching device and the target internet of things platform to obtain a target address corresponding to the target internet of things platform, that is, an IP address of the target internet of things platform. It can be understood that an MQTT (chinese full name: Message queue Telemetry Transport protocol, english full name: Message Queuing telemetering Transport) tunnel can be established between the switching device and the target internet of things platform, that is, the establishment of the communication connection with the target internet of things platform includes: and establishing an MQTT tunnel between the switching equipment and the target Internet of things platform, wherein the MQTT tunnel is used for communication connection between the switching equipment and the target Internet of things platform. Certainly, a TCP connection may also be established between the switching device and the target internet of things platform, and in order to ensure communication security, an encrypted TCP connection may be established.
S102: if the access of the target equipment is identified, a virtual IP address is allocated to the target equipment; wherein the target device is an acquisition layer device;
in this step, if the acquisition layer device that is allowed to access, i.e. the target device, is identified, a Virtual Local Area Network (VLAN) is allocated to a Network port of the target device, and the VLAN provides a DHCP (Dynamic Host Configuration Protocol, which is a chinese full name) service, and allocates a Virtual IP address to the target device.
As a possible implementation, the present step includes: receiving a request message of a device to be accessed, and judging whether a protocol identifier of the device to be accessed is a protocol identifier corresponding to a preset protocol type based on a protocol identifier in the request message; if so, determining that the equipment to be accessed is the target equipment, and sending an address allocation message containing a virtual IP address to the target equipment, wherein the address allocation message is used for allocating the virtual IP address to the target equipment.
In a specific implementation, the POE switch may automatically identify an accessed target device through a two-layer broadcast message, that is, the target device automatically sends the two-layer broadcast message, where the two-layer broadcast message includes a 12-byte MAC (Media Access Control Address, full name of chinese), a 2-byte protocol identifier, a 2-byte device type, and a 6-byte device SN (Serial Number, full name of chinese), and the POE switch determines whether a protocol identifier in the received two-layer broadcast message is a protocol identifier corresponding to a preset protocol type. If yes, the accessed equipment is judged to be target equipment, and a virtual IP address is allocated to the target. It can be understood that an implementer can set a protocol identifier corresponding to a preset protocol type to limit devices accessing to the internet of things platform, and security is guaranteed.
Taking the target device as a DTU device as an example, as shown in fig. 3, the POE switch may automatically identify an DYU device to be accessed through a two-layer broadcast message, and a network port to be accessed to the DTU is divided into a dedicated VLAN. After the DHCP service configuration is completed, the DTU device automatically sends a broadcast message of the DHCP discover, and the POE switch receives the broadcast message of the DHCP discover, analyzes the message and returns a DHCP offer message to inform the DTU device that the DHCP service can be provided. The DTU equipment sends a dhcp request message and requests the POE switch for information such as a virtual IP address, a mask code, a gateway, a DNS and the like. And the POE switch sends a dhcp ack confirmation message to the DTU equipment to inform the DTU equipment of using the virtual IP address.
S103: sending a first UDP broadcast message containing the target address to the target equipment, wherein the first UDP broadcast message is used for setting an Internet of things platform address of the target equipment as the target address, and the Internet of things platform address is used for accessing the target equipment to the target Internet of things platform.
The purpose of this step is to set the internet of things platform address of the target device as the IP address of the target internet of things platform, i.e. the target address, so as to realize that the target device accesses the target internet of things platform. In a specific implementation, the switching device sets an internet of things platform address of the target device through a UDP (User Datagram Protocol, User data Protocol, english, etc.) broadcast message. The UDP broadcast includes a UDP message header, a command identifier, a command type, a device MAC, a device IP, a device network mode, a device IOT platform address, a device serial port parameter, and the like.
And the switching equipment discovers and sets the parameter information of the target equipment through the command type according to the command identifier 'SUNDRAY' verification command. The command type includes 0x00, 0x01, and 0x02, where 0x00 indicates that the target device automatically reports its own parameter information, 0x01 indicates that the POE switch requests the parameter information of the target device, and the command 0x02 indicates that the POE switch sets the parameter information of the DTU device, including the internet of things platform address. The POE switch may set the internet of things platform address of the target device through the first UDP broadcast message, i.e., the command 0x 02.
In the embodiment of the application, the target equipment which is the acquisition layer equipment needing to be accessed to the Internet of things platform is automatically identified through the exchange equipment, the configuration service of the virtual IP address is provided for the target equipment needing to be accessed, and the real IP address resource is saved as the virtual IP address is allocated to the target equipment. Meanwhile, the exchange equipment is in communication connection with the Internet of things platform and used for obtaining the target address of the Internet of things platform, and the Internet of things platform address of the target equipment is set to be the target address in batches through the exchange equipment, so that batch target equipment can be accessed to the Internet of things platform. Therefore, the equipment access method of the Internet of things platform provided by the embodiment of the application reduces the workload of configuring the IP address of the target equipment and the address of the Internet of things platform in a large scale, improves the efficiency of accessing the acquisition layer equipment to the Internet of things platform, and saves IP address resources.

s202: receiving a request message of a device to be accessed, and judging whether a protocol identifier of the device to be accessed is a protocol identifier corresponding to a preset protocol type based on a protocol identifier in the request message; if yes, entering S203;
s203: determining the device to be accessed as the target device, determining a target virtual local area network corresponding to the target device, and sending an address allocation message containing a target virtual IP address to the target device, wherein the address allocation message is used for allocating the virtual IP address to the target device; wherein the target virtual IP address is a virtual IP address in the target virtual local area network;
in this embodiment, in order to prevent tampering and attack between different network ports, network ports of different target devices are matched in virtual local area networks with different values, that is, target devices are assigned with target virtual IP addresses in corresponding target local area networks.
As a preferred embodiment, determining a target virtual local area network corresponding to the target device includes: and determining the target equipment type of the target equipment in the request message, and determining a target virtual local area network corresponding to the target equipment type based on the corresponding relation between the equipment type and the virtual local area network. In specific implementation, the switching device determines the device type of the device to be accessed according to the device type in the two-layer broadcast message, so as to allocate a dedicated virtual local area network to the network port of the device to be accessed, allocate devices of the same device type to the same virtual local area network, allocate devices of different device types to different virtual local area networks, prevent tampering and attack between different network ports, and play a role in security isolation.
S204: sending a first UDP broadcast message containing the target address to the target equipment, wherein the first UDP broadcast message is used for setting an Internet of things platform address of the target equipment as the target address, and the Internet of things platform address is used for accessing the target equipment to the target Internet of things platform.
Therefore, the target devices of different device types are allocated to different virtual local area networks, tampering and attack between different network ports are prevented, and a safety isolation effect is achieved.
The embodiment of the application discloses an equipment access method of an Internet of things platform, and compared with the first embodiment, the embodiment further describes and optimizes the technical scheme. Specifically, the method comprises the following steps:
referring to fig. 5, a flowchart of a device access method for a third internet of things platform according to an exemplary embodiment is shown, and as shown in fig. 5, the method includes:

In specific implementation, the target device to be accessed is reported to the target internet of things platform by the switching device, the target internet of things platform adds the target device to the list of the newly discovered device, and the user can log in the target internet of things platform and add the target device to the list of the newly discovered device. When the switching device inquires that the target device is added to the target internet of things platform, the internet of things platform address of the target device is set through a first UDP broadcast message, namely a 0x02 command.
On the basis of the above embodiment, as a preferred implementation, the present embodiment further includes: receiving a second UDP broadcast message sent by the target equipment; the second UDP broadcast message comprises an address of an Internet of things platform accessed by the target equipment; judging whether the address of the Internet of things platform in the second UDP broadcast message is the target address or not; if not, reporting the equipment identifier of the target equipment to the target Internet of things platform; and sending a first UDP broadcast message containing the target address to the target equipment.
In specific implementation, after receiving a second UDP broadcast message, that is, a 0x00 command, sent by a target device, a switch device reports a newly discovered target device to a target internet of things platform if it is detected that an internet of things platform address of the target device is inconsistent with a target address connected to the switch device, and the target internet of things platform adds the newly discovered target device to a list of the newly discovered device if it is detected that the target device is not added. It is understood that the target device may transmit the second UDP broadcast packet at a preset period. The user can log in the target Internet of things platform and add the DTU equipment in the newly discovered equipment list. When the switching device inquires that the target device is added to the target internet of things platform, the internet of things platform address of the target device is set through a first UDP broadcast message, namely a 0x02 command. That is, sending a first UDP broadcast packet including the destination address to the destination device includes: and if receiving a confirmation adding instruction of the target Internet of things platform, sending a first UDP broadcast message containing the target address to the target equipment.

The POE switch establishes an MQTT tunnel with the IOT platform, the DTU equipment sends the IOT platform address of self, namely the target address, to the POE switch through udp broadcast request, and the POE switch judges whether the target address corresponds to the IOT platform, if so, does not process, if not, inquires whether the DTU equipment adds to the IOT platform. If not, the DTU equipment is added to a discovery list of the IOT platform, after the user discovers and adds the DTU equipment, the POE switch sets an IOT platform address of the DTU equipment through udp, and the DTU equipment and the IOT platform establish a TCP tunnel.
Therefore, in this embodiment, the switching device sets the internet of things platform address of the target device as the target address corresponding to the target internet of things platform in batch through the first UDP broadcast message, so that batch target devices are accessed to the internet of things platform, the workload of configuring the internet of things platform address of the target device in a large scale is reduced, and the efficiency of accessing the acquisition layer device to the internet of things platform is improved.
