Detailed ways

In order to enable those skilled in the art to better understand the technical solution of the utility model, and to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described below in conjunction with the embodiments and accompanying drawings Detailed explanation.

FIG. 1 is a schematic diagram of the overall hardware architecture of the embodiment of the present invention. The utility model provides a network home system based on the Internet of Things. In this system, all household appliances such as televisions, air conditioners, washing machines, heating systems, video security monitoring systems, lighting equipment, curtain driving equipment, information equipment such as PCs, and communication terminals such as telephones used in households can be used as the picture. The home terminal device 1 in 1. In the existing technology, these terminal devices come from different manufacturers, have control circuits with different architectures inside, and use different communication methods to communicate with the outside world. Therefore, it is difficult to use a unified communication method to integrate these devices into a unified IoT network. However, in the present utility model, these home terminal devices 1 are respectively built with a unified network interface circuit 2, and through the network interface circuit 2, these home terminal devices 1 are connected to the home gateway device through the home internal network in a unified communication mode. 3. Since the network interface circuit 2 adopts a unified communication protocol, the home gateway device 3 can implement data communication and command control with each home terminal device 1 in a unified data format and command format. The network interface circuit 2 shields the differences in communication methods of home terminal devices of different manufacturers, and makes all home terminal devices 1 form a unified platform by connecting to the home gateway device 3. Users can connect to the home gateway device 3 through the Internet 4 to unify The communication control method realizes interaction and control with various home terminal devices 1 in the platform.

Fig. 2 shows the structure diagram of the network interface circuit. The network interface circuit 2 includes a digital communication circuit 2A, a protocol conversion chip 2B and a terminal interface circuit 2C; the terminal processor 1A of the home terminal device 1 is connected to the terminal interface circuit 2C. The digital communication circuit 2A performs connection and data communication with the home gateway device 3 . In recent years, wireless network access technology has developed rapidly, and wireless access has strong scalability, flexibility and convenience. Therefore, the digital communication circuit 2A can adopt a wireless communication circuit based on wireless access protocols such as WIFI, and correspondingly , the home gateway device 3 is a wireless access gateway device. For home terminal devices of different manufacturers, their internal control circuits adopt their own unique control protocols, so the protocol conversion chip 2B performs format conversion on communication data and control commands, so that the digital communication circuit 2A communicates with the home gateway device 3 The data and command format used in the home terminal device 1 and the data and command format that can be recognized and processed by the terminal processor 1A inside each home terminal device 1 are mutually converted, and the terminal interface circuit 2C is used as the connection interface with the terminal processor 1A. Therefore, through the network interface circuit 2, various home terminal devices can communicate with the home gateway device based on a unified protocol, and enable various home terminal devices to perform internal operation control according to their unique protocols. Moreover, in home applications, the internal circuits of various terminals have obvious differences. Home terminals such as TVs and PCs generally have processor chips with strong computing and processing capabilities inside, while controls such as lighting equipment and curtain driving equipment The circuit often only has a simple single-chip circuit, and does not have the hardware processing ability to perform network communication. Therefore, the network interface circuit 2 uses an independent digital communication circuit 2A and a protocol conversion chip 2B to complete network access, data communication and format conversion. Differences in communication and digital processing capabilities of various home terminal devices.

Referring to FIG. 1 , the network home system further includes a centralized home center controller 5 and a centralized data manager 6 . The home center controller 5 is connected to the home gateway device 3 , and its specific structure is shown in FIG. 3 , including a digital communication circuit 5A, a CPU chip 5B, a man-machine interface 5C and a display 5D. The digital communication circuit 5A realizes the connection and communication with the home gateway device 3, and the CPU chip 5B performs the centralized control function, so that the home center controller 5 is used for centralized setting, monitoring and control of the operation status of the entire network home system. For example, whether the working status of various home terminal devices in the network home system is normal can be uniformly monitored by the home center controller 5 , and the working hours and working modes of various home terminal devices can be uniformly set by the home center controller 5 . The user can remotely access the home center controller 5 through the home gateway device 3 based on the Internet 4. At the same time, the home center controller 5 also provides a human-machine interface 5C such as a keyboard or a touch panel and a display 5D, which can be controlled by the user at home. The controller 5 is directly operated and set. The centralized central control system provides convenience for the application of the home system. For example, the user wants to automatically open the curtains at 7 o'clock every morning, turn off the lights at the same time, and turn on the TV to watch the morning program. Set the TV, lighting equipment, and curtain driving equipment, but according to the utility model, it can be realized by simply performing a simple time setting operation on the home center controller 5 .

The centralized data manager 6 is connected to the home gateway device 3, and the centralized data manager 6 includes a data memory and a data processing chip. In the past digital home system, the relevant data of various home terminal equipments were scattered and stored in their corresponding memory, which was not convenient for centralized management of data, and was not conducive to data security. The centralized data manager 6 is used for centralized management and storage of various data in the network home system, such as the monitoring screen data captured by the video security system, the caller number data recorded by the home phone, etc., are all stored in the centralized data manager 6 In this way, it is convenient for users to remotely call these data information through the Internet 4, and it is also convenient for centralized management of data. For example, if a user wants to regularly back up data such as home monitoring screens, call number records, and access control access records to a remote server, in the past, the data can only be uploaded by accessing the security system, access control system, and telephone system separately. The system only needs to set up the centralized data manager 6, and can directly upload relevant data in the data memory of the centralized data manager 6 to the network server regularly, without needing to access the security system, access control system, and telephone system separately.

To sum up, the utility model realizes the connection with the home gateway device through the unified network interface circuit built in various home terminal devices with a unified communication protocol, so that various devices can be integrated into a unified network home platform, realizing Unified access to the Internet, and the utility model also adopts centralized central control and data management. Utilizing the network home system of the utility model can effectively promote the popularization of the application of the network home technology in real life, improve the informatization and automation level of the whole home, and bring sufficient convenience to people's life.
