Description

A control method for distributed user equipment

technical field

The present invention relates to the technical field of equipment control, in particular to a control method of distributed user equipment.

Background technique

With the popularization of the concept of smart home and the widespread application of smart home devices, people's requirements for network communication in smart homes are constantly improving. At present, most smart homes use wireless connection communication methods. In terms of network stability and performance, they cannot be compared with traditional computers, resulting in poor real-time device control and data transmission.

SUMMARY OF THE INVENTION

In order to solve the above problems, the present invention provides a control method for distributed user equipment, and the specific technical solutions are as follows:

A control method for distributed user equipment. The user equipment is connected to a server through a WIFI gateway, and the server is connected to a control APP. The user equipment communicates with the WIFI gateway through the LonTalk protocol; the server communicates with the WIFI gateway through the TCP/IP Sokcet protocol; the server communicates with the control APP through the WebSokcet protocol;

The control method includes the following steps:

S1: Collect and upload the status data of the user equipment to the server through the WIFI gateway;

S2: The server stores the state data of the user equipment in the database and pushes it to the control APP;

S3: The user checks the status of the user equipment through the control APP and sends a control command;

S4: After the server receives the control instruction, the server sends it to the user equipment through the WIFI gateway to control the state of the user equipment.

The LonTalk protocol follows the ISO/OSI model and provides all seven-layer services defined by the OSI reference model. It is a direct object-oriented network protocol, which is not supported by communication buses such as RS485. This establishes a common standard for the exchange of control status information between devices, integrates those isolated systems and products in the past, and solves the problem of interoperability between products of different manufacturers, so that a system can be formed within a residential area. Unified network control system.

Socket transmits data at the byte level, and the transmitted data can be customized. The amount of data is small, which can save the traffic cost of mobile phone applications; the data transmission time is short and the performance is high; it is suitable for real-time information exchange between the client and the server; it can be encrypted, Strong data security.

The WebSokcet protocol implements multiplexing, is full-duplex communication, supports persistent connections, and the server actively pushes information to the client, which solves the problem of delay in the synchronization of the http protocol.

Through the application of the above three protocols in each link of the system, the communication efficiency can be effectively improved and the effect of real-time control can be achieved.

Preferably, the user equipment is connected to the WIFI gateway through a LonWorks module.

Preferably, the WIFI gateway converts the information of the LonWorks module into WIFI interface information, collects the data of the LonWorks module, and converts the LonTalk communication protocol to the TCP/IP protocol and transmits it from the WIFI interface to the server.

The LonWorks module includes the LonWorks chip. The user equipment binds variables through the LonWorks chip. When the state of the user equipment changes, the LonWorks chip immediately pushes the state data of the user equipment to the server connected to the upper layer.

Preferably, the data interaction method between the server and the control APP includes establishing a secure communication connection, sending and pushing data, maintaining and disconnecting the connection, and the details are as follows:

(1) Establish a secure communication connection:

1) The user logs in the user on the login interface of the control APP. After the login is successful, the server saves the SessionID passed by the control APP;

2) The control APP carries the SessionID to carry out the WebSokcet connection request. After the server receives the request, it first checks the validity of the SessionID, establishes a connection with the control APP after the verification is passed, and pushes the currently collected state information of the user equipment to the control APP;

(2) Data distribution and push:

1) When controlling the APP to control the device, the control APP first detects the connection status with the server, and if the connection is not interrupted, it sends a control command to the server. The results are fed back to the control APP;

2) When the status of the user equipment changes, the user equipment pushes the status information to the server through the WIFI gateway; after the server receives the status information of the user equipment, it first checks all WebSokcet connections, and pushes the status data of the user equipment to all available connections;

(3) The connection is maintained and disconnected:

Control the APP to regularly detect the connection status with the server. If it is found to be disconnected, it will continuously try to connect to the server.

The beneficial effects of the present invention are:

In the present invention, the user equipment communicates with the WIFI gateway through the LonTalk protocol, which effectively solves the shortcomings of network instability, poor penetration and coverage with blind spots caused by using the wireless communication module as the internal network of the smart home. The server communicates with the WIFI gateway through the TCP/IP Sokcet protocol; the server communicates with the control APP through the WebSokcet protocol, which can quickly and safely obtain the real-time status of the device without wasting a lot of mobile phone resources.
