[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, the intelligent building network system of the present invention includes a communication gateway, an Internet of Things gateway, and an edge control device;

[0030] Among them, the edge control device is connected to the public network and private network of the intelligent building, and has a variety of communication and IoT facility management and control modules, which respectively manage and control various front-end devices. The edge control device is connected to several communication gateways; the communication gateway is connected to several Ethernet communication front-end devices and IoT gateways, which are used to converge the signals of related front-end devices; the IoT gateway is connected to several IoT front-end devices, which are used to converge the signals of related IoT front-end devices and convert or encapsulate various protocols into standard Ethernet signals.

[0031] At the same time, a unified end-to-end VLAN channel is set up between the edge control device, communication gateway and IoT gateway for each type of IoT service and communication service of the smart building, thereby realizing network bandwidth isolation and security isolation. Each type of IoT service and communication service in the building can be uploaded from the Ethernet communication front-end device or IoT front-end device to the communication gateway along its exclusive VLAN channel, and then uploaded to the edge control device, and then distributed by the edge control device to the corresponding public network or private network, such as the wireless core network, wired network and the private network of the intelligent building integrated management system, so as to realize the orderly layout of various network devices in the building, unified deployment of lines, unified management and distribution, and reduce the difficulty of implementing building intelligence.

[0032] Specifically, Figure 2 As shown, the edge control device includes several virtual IoT management modules, such as IoT management modules 1, 2, and n, etc. Various IoT front ends are connected to corresponding management modules to perform access control and authentication of various services and front-end terminals.

[0033] The edge control device also includes a wireless control module, a wired control module, a WLAN control module, etc.

[0034] The virtual IoT management module can manage and control IoT front-end devices, including automatic device discovery, automatic device access, device authentication, IoT data access, and can also connect IoT business data to a dedicated network, such as the smart building integrated management system. Smart building users can log in to the smart building integrated management system through terminal devices or mobile client to view, manage and control IoT business data, thus realizing building IoT and intelligent management.

[0035] Wireless control modules, wired control modules, WLAN control modules, etc. are used to manage and control Ethernet communication front-end devices, including automatic device discovery, automatic device access, device authentication, and communication data access, and can connect communication business data to the public or private network of the building.

[0036] The wireless control module can be independently connected to the operator's 4G and 5G wireless core networks; depending on the scale of the specific scenario, POI devices, indoor distributed HUBs, etc. can be set up in the wireless control module. In large-scale scenario applications, BBU devices can also be set up in the wireless control module.

[0037] The WLAN control module can realize the functions of AC and other related management and control functions.

[0038] like Figure 3As shown, the communication gateway includes indoor distributed RRU equipment and Ethernet switches; it is connected to indoor distributed antennas through indoor distributed equipment, and to WIFI, IoT gateways and other networking devices through Ethernet switches. Indoor distributed antennas, WIFI, Bluetooth and other networking devices together constitute Ethernet communication front-end equipment.

[0039] The Ethernet communication front-end device converges the communication business data and uploads it to the edge control device through the uplink interface of the communication gateway. The edge control device then distributes it to the wireless control module, wired control module, WLAN control module, etc., and connects it to the public network or private network in the building.

[0040] The uplink interface of the communication gateway is a mixed line module, which includes both indoor distribution cable interfaces and Ethernet cable interfaces, so that indoor distribution cables and Ethernet cables can be combined into one set of interfaces, thereby simplifying the layout of the lines.

[0041] The IoT gateway is the link between the perception network and the traditional communication network, realizing the protocol conversion between the perception network and the communication network, as well as between different types of perception networks. It can realize both wide-area interconnection and local-area interconnection. In addition, the IoT gateway also needs to have the function of device management. Through the IoT gateway device, the underlying perception nodes can be managed, the relevant information of each node can be understood, and remote control can be realized.

[0042] like Figure 4 As shown, the IoT gateway includes an Ethernet switch and several protocol conversion modules connected to the Ethernet switch; the protocol conversion module is connected to several IoT front-end devices, such as light monitoring equipment, radar monitoring equipment, smoke monitoring equipment, environmental monitoring equipment, navigation and positioning equipment, RFID equipment, security monitoring equipment, temperature and humidity monitoring equipment, PM25 monitoring equipment, CO2 monitoring equipment, indoor personnel detectors, etc. At the same time, the protocol conversion module can convert or encapsulate the IoT business data collected by the IoT front-end equipment into Ethernet signals, and upload them to the Ethernet switch in the IoT gateway through the VLAN channel corresponding to the IoT business data. The Ethernet switch is used as the uplink interface of the IoT gateway, which is connected to the communication gateway, and then connected to the edge control device by the communication gateway, and distributed by the edge control device to each virtual IoT management module, and then connected to the public network or private network in the building, so as to realize the building IoT and intelligent management.

[0043] Between the edge control device and the Ethernet switch built into the communication gateway and IoT gateway, different IoT and communication services are set up with a unified VLAN channel end-to-end to achieve virtual network bandwidth isolation, exclusive and secure isolation, that is, an end-to-end virtual channel is established for each type of IoT application. Internet services such as WiFi that need to access the public network are connected through the wired access control module. Services that do not need to go out of the public network, such as smart building services, are directly connected to the local smart building integrated management system. 4G / 5G indoor distribution services are connected from the communication gateway to the edge control device to establish a physical independent channel.

[0044] In order to further facilitate management, the ability of the edge control device to connect to the communication gateway is increased, and the ability of the communication gateway to connect to the Ethernet communication front-end device and the Internet of Things gateway is increased. Switching and convergence can also be set up between the edge control device and the communication gateway. In order to reduce the difficulty of implementing building intelligence and solve the problem of many lines in building intelligence, affecting the appearance and inconvenience of later maintenance, the communication gateway, the Internet of Things gateway, the front-end equipment of the communication or the front-end equipment of the Internet of Things can be built into the lighting fixtures, so that the communication lines and the Internet of Things lines can be laid together with the lighting lines in the building, reducing the space occupied by the lines, and can be planned uniformly and laid once, which greatly improves the convenience of implementation and is conducive to promoting building intelligence.

[0045] The present invention connects various communication front-end devices and IoT front-end sensing devices in the building to the edge control device through the IoT gateway and the communication gateway, realizes unified deployment and unified management, and reduces the difficulty of implementing building intelligence. At the same time, the IoT gateway, the IoT gateway, the communication front-end device or the IoT front-end device can be built into the lighting fixture, and its lines can be laid together with the lighting lines, which solves the problem of too many lines affecting the appearance, and also facilitates the later maintenance, effectively solves the construction and management problems, and greatly improves the construction and operation efficiency.

[0046] The specific implementation method of the present invention is described below by taking the Internet of Things and Ethernet deployment system of a building as an example.

[0047] The IoT terminal devices in the building, such as smoke monitoring devices, are connected to the protocol conversion module in the IoT gateway through wired or wireless access. The protocol conversion module encapsulates or converts the data of the smoke monitoring device into Ethernet data and sends it to the Ethernet switch in the IoT gateway, which is then sent to the communication gateway connected to the IoT gateway. After receiving the information, the Ethernet switch in the communication gateway continues to send it to the edge control device connected to it. The edge control device distributes the information to the corresponding network.

[0048] Before the data is distributed upstream, a unified VLAN channel is set up end-to-end between the edge control device and the Ethernet switch built into the communication gateway and IoT gateway for different IoT and communication services. In other words, as a type of IoT service, the smoke monitoring device will encapsulate and convert the monitored data through the protocol conversion module in the IoT gateway and send it to the Ethernet switch in the IoT gateway. The data will then be transmitted in the VLAN channel dedicated to the smoke monitoring device. Finally, the edge control device will distribute the data to the corresponding proprietary network, so that the data collected and monitored by all smoke monitoring devices in the building can be aggregated through the VLAN channel.

[0049] The same is true for Ethernet communications within buildings, including wired networks, wireless networks, WiFi, 4G, 5G and other mobile signals.
