Figure 2 shows a flow chart of a general peripheral access gateway registering an electrical device. The registration process mainly includes the following steps:

Step 201: The universal peripheral access gateway registers with the Internet of Things platform (management platform/service platform), and the registration follows the Internet of Things management protocol.

Step 202: When a new electrical device is accessed, the universal peripheral access gateway can detect the access of a new peripheral (new electrical device).

When a new electrical device is connected to the extended access module 10 of the universal peripheral access gateway, the extended access module 10 can monitor the access of the electrical device.

Step 203: The universal peripheral access gateway initiates a registration request of the new peripheral to the Internet of Things platform.

Table 1

The attribute data can be automatically reported when the new peripheral is registered, or can be actively acquired by the extended access module 10 of the universal peripheral access gateway through the proprietary protocol used by the peripheral.

Step 204: The Internet of Things platform performs registration authentication of the new peripheral according to the registration request reported by the universal peripheral access gateway.

Step 205: The Internet of Things platform returns the registration authentication result to the universal peripheral access gateway. Step 206: The universal peripheral access gateway performs corresponding processing according to the registration authentication result. For the new peripheral with successful registration authentication, the universal peripheral access gateway normally executes the subsequent Internet of Things platform and the new external Set the message exchange between; for the new peripheral that fails the registration authentication, the universal peripheral access gateway stops docking with it, and does not process subsequent messages related to the new peripheral.

It should be noted that if the universal peripheral access gateway detects the change of the connected peripheral, it needs to initiate a re-registration process to the Internet of Things platform. The re-registration process is similar to the registration process shown in Figure 2, and will not be described here. .

For a disabled peripheral, when it needs to be restored, the universal peripheral access gateway can initiate a recovery request to the IoT platform, and after receiving the recovery request, the IoT platform removes the deactivation information of the disabled peripheral; After the peripheral access gateway receives the confirmation message from the Internet of Things platform, it starts the support for the peripheral.

In addition, the IoT platform can also actively send management messages to the universal peripheral access gateway to initiate requests for active management of peripherals; requests can include: deleting, disabling, enabling some or some peripherals. After the Universal Peripheral Access Gateway deletes or disables a peripheral, it no longer accepts incoming and outgoing messages related to the peripheral.

Figure 3 shows a flow chart for packet report processing. The process of message report processing mainly includes the following steps:

Step 301: The peripheral device (that is, the external device connected to the universal peripheral access gateway) sends a message to the universal peripheral access gateway.

The peripheral sends the reported message to the corresponding extended access module 10 of the universal peripheral access gateway. For example, the Zigbee-enabled electrical device reports the message to the Zigbee access module of the universal peripheral access gateway, and the Bluetooth-enabled appliance The device reports the message to the Bluetooth access module of the universal peripheral access gateway.

Step 302: The universal peripheral access gateway receives the message through its universal extension interface 20. The extended access module 10 provides the received message to the universal extension interface 20 in the communication mode supported by the universal extension interface 20. For example, the Zigbee access module converts the message reported by the Zigbee-enabled electrical device into the universal extension interface 20. Common communication interface 20, the Bluetooth access module converts the message reported by the Bluetooth-enabled electrical device into a universal expansion interface

The 20 supported communication modes are then provided to the universal extension interface 20.

Step 303: The universal peripheral access gateway performs protocol adaptation of the application layer on the received packet. The universal extension interface 20 provides the received message to the application layer protocol adaptation module 30, and the application layer protocol adaptation module 30 performs protocol adaptation of the application layer to convert the message into a standard data format.

Step 304: The universal peripheral access gateway sends the adapted message to the Internet of Things platform (management platform/service platform;).

The application layer protocol adaptation module 30 provides the packet converted to the standard data format to the standard protocol transceiver module 40, and the standard protocol transceiver module 40 transmits the packet to the Internet of Things platform through the wide area network.

FIG. 4 is a flowchart of a process for delivering a message, and the process of delivering the message mainly includes the following steps:

Step 401: The Internet of Things platform sends a message to the universal peripheral access gateway, where the message carries the identifier of the peripheral device (also referred to as the destination peripheral device, that is, the destination electrical device).

Step 402: The universal peripheral access gateway receives the packet sent by the Internet of Things platform through the standard protocol transceiver module 40, and the received packet is in a standard protocol format.

Step 403: The universal peripheral access gateway converts the received message, and sends the converted message to the corresponding extended interface module 10.

After receiving the packet sent by the Internet of Things platform, the standard protocol transceiver module 40 searches for the application layer protocol adaptation module 30 corresponding to the internal and destination peripherals according to the identifier of the destination peripheral carried in the packet, and finds The application layer protocol adaptation module 30 converts the standard protocol format message into a data format used by the destination peripheral. Then, the application layer protocol adaptation module 30 provides the converted message to the universal extension interface 20; The expansion interface 20 finds the extended access module 10 corresponding to the destination peripheral by addressing in the general peripheral access gateway according to the communication mode used by the destination peripheral, and sends the converted message to the found extended access. Module 10. For example: if the purpose The communication mode used by the peripheral is Zigbee, and the universal extension interface 20 finds the Zigbee access module through addressing, and sends the converted message to the Zigbee access module.

Step 404: The extended interface module 10 of the universal peripheral access gateway sends the message to the corresponding destination peripheral according to the external identifier and address carried in the packet.

It should be noted that, for the conversion between the data format used by the peripherals executed by the application layer protocol adaptation module 30 and the standard data format, a Key-Value method can generally be adopted as the standard data format. The way to represent the Key-Value data format mainly includes TLV and Extensible Markup Language (XML).

The TLV is an abbreviation of Tag, Length, and Value, Tag indicates the data identifier, Length is the data length, and Value is the actual value of the data. In theory, any data can be represented by a Tag, and the length and value of the data are packaged together for transmission. The receiver and sender only need to define the definition of Tag. Specific to the management and control of various electrical equipment in the smart home business, the operation of the electrical equipment can be defined as a set of identification systems, each of which corresponds to a tag. In this way, the interface instructions of different manufacturers' devices can be converted into standardized TLVs according to certain rules in the application layer, so that the smart home service platform or the management platform on the platform side can be processed, and the operation of the electrical equipment on the platform side can also be performed. The TLV is converted to a proprietary protocol of the appliance manufacturer and sent to the electrical device for execution.

XML is used to represent the standard data format. The principle is similar to TLV. A set of XML tags can be defined to correspond to the device operation or status, so that the platform side can manage and control the electrical equipment of different manufacturers.

The following takes TLV as the standard data format as an example, and combines the scene of air conditioning control to explain the management and control of peripherals on the platform side. The management and control operations mainly include the following steps:

Step 1. The user logs in to the portal of the smart home application platform and selects an air conditioner of his own. Step 2: The user selects the operation of the air conditioner. In this embodiment, the temperature of the air conditioner is set.

Step 3, the service platform will express the setting instruction of the air conditioner temperature as a TLV format, and then pass The WAN sends a message to the universal peripheral access gateway that accesses the air conditioner.

Step 4: The standard protocol transceiver module 40 of the universal peripheral access gateway receives the message and parses the message.

Step 5: The standard protocol transceiver module 40 of the universal peripheral access gateway sends the parsed data to the application layer protocol adaptation module 30, and the application layer protocol adaptation module 30 converts the message into a private protocol packet used by the air conditioner. format.

Step 6, the application layer protocol adaptation module 30 sends the generated private protocol message to the universal extension interface 20.

Step 7. The universal extension interface 20 sends a message to the extension access module 10 that accesses the communication mode according to the communication mode adopted by the air conditioner.

Step 8: The extended access module 10 sends an application layer message to the air conditioner according to a communication mode supported by the air conditioner (for example, 433 or Zigbee).

It can be seen from the above embodiments that the embodiment of the present invention deploys a universal peripheral access gateway on the terminal side, and after the universal peripheral access gateway registers with the platform that provides the service and management functions, it only needs to add corresponding according to actual needs. Expand the access module, and download the corresponding application layer protocol adaptation module from the device manufacturer's website. After installation on the universal peripheral access gateway, the platform can communicate with the newly added peripherals.

When the extended access module detects a new peripheral access, it registers with the management platform or service platform through the universal peripheral access gateway, notifying the platform that there is a new peripheral access. When the peripheral connected to the universal peripheral access gateway changes, it also initiates a change to the platform, and the change can only be accepted after the platform is authorized.

In summary, the embodiments of the present invention have the following beneficial effects:

1. Solve the problem that the electrical equipment of different manufacturers in the smart home application is incompatible with each other, and can easily extend the support of the universal peripheral access gateway to the electrical equipment, and only need to add an extended access module according to actual needs (with the universal expansion interface) Implement physical connections) to support access to new peripherals Style

3. A platform has been implemented to provide business services and control for many smart home electrical appliances. At the same time, the thin client at the terminal side has been realized, which has reduced the user's equipment investment, which is conducive to centralized operation of the smart home business. The user's stickiness to the operator;

4. The packets of different private protocols are expressed in a unified standard format, enriching the smart home service, promoting the operation of the smart home business, and reducing the cost of implementing the smart home business.

The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
