Description

Technical Field

[0001] The utility model relates to a gateway device, in particular to a EUHT multi-mode gateway. Background Art

[0002] At present, smart cities are mainly based on 4G, 5G + NB-IoT public networks, or some narrowbands are deployed using LoRaWAN networks, where public networks refer to China Mobile, China Telecom, and China Unicom. The NB-IoT refers to the Narrow Band Internet of Things (NB-IoT), which is becoming an important branch of the Internet of Everything. NB-IoT is built on cellular networks and consumes only about 180kHz of bandwidth. It can be directly deployed on GSM networks, UMTS networks, or LTE networks to reduce deployment costs and achieve smooth upgrades. The LoRaWAN is an open network protocol that provides secure two-way communications, mobility, and localization services standardized and maintained by the LoRa Alliance.

[0003] The above-mentioned technical applications have the following pain points: ① Due to the limitation of the base station network signal environment, the signal coverage of the entire area cannot be achieved. In actual deployment, the sensors of the Internet of Things can only work normally in areas with good signals. Taking the Haidian Smart City project area as an example, the operator still cannot meet the full coverage requirements after network optimization; ② The NB-IoT signal transmission quality is poor. When it encounters environmental interference such as rain, wind, and strong electromagnetic interference, the indoor signal quality is poor and the data upload is unstable, which makes repeated reporting reduce the battery life of the equipment; ③ Due to the limitation of the number of concurrent data in the base station sector, the system uses delay to process discrete, which affects the real-time nature of data in some application scenarios and cannot achieve real-time transmission; ④ The 5G network signal service fee is high, the energy consumption is high, and the maintenance cost is high; ⑤ 4G and 5G are public networks (non-isolated physical environments) rather than private networks, which are not suitable for production network requirements and are difficult to implement in many actual projects.

[0004] According to the Beijing Urban Master Plan (2016-2035), it is necessary to focus on implementing the development requirements proposed in the master plan, such as "reducing the scale of urban and rural construction land, optimizing and improving the functions of the capital, creating a good living environment, coordinating the use of above-ground and underground space, and promoting the coordinated development of transportation and cities". The zoning plan identifies the edge of Dongba as a "production-residence integrated development group, which should strengthen the service and supporting support for the core functions of the capital, focus on improving urban functions and spatial configuration, optimize the relationship between work and residence, and drive the urbanization construction of green isolation areas. Through the development of functional dislocation, we will continuously supplement and improve various public service facilities at all levels, strengthen transportation and infrastructure construction, vigorously improve the quality of the environment, and form an important carrier for the extension of the capital's functions and supporting services."

[0005] Since its development began in 2006, after three rounds of six-year incubation with support from major national science and technology projects, EUHT-5G has become the Ministry of Industry and Information Technology's communications industry standard, intelligent transportation national standard, rail transit industry application standard and national information and communication standard in standard documents such as "Real-time Video Transmission System between Urban Rail Transit Vehicles and Ground", "Media Access Control and Physical Layer Specifications for High-Speed ​​Wireless LANs for Remote Communication and Information Exchange between Information Technology Systems", "Dedicated Short-Range Communications for Cooperative Intelligent Transport Systems", and "Technical Requirements for Wireless LANs with High Spectrum Utilization and High Data Throughput".

[0006] The EUHT module of Beijing Investment New Shoreline has been fully verified, and its technical performance has the advantages of high reliability, low latency, large capacity and high-speed mobility adaptability; economically, it has strong competitiveness in low network construction cost and operation cost. The EUHT system has the characteristics of high throughput, high reliability, high-speed mobility, low latency, low cost and low power consumption, precise positioning, precise calculation, and fine control, and is widely used in intelligent networking, high-speed railways, urban rail transit, industrial interconnection, wireless broadband coverage and other fields.

[0018] Figure 2 It is a structural diagram of the EUHT multi-mode gateway. DETAILED DESCRIPTION

[0019] like Figure 1 and Figure 2 The EUHT multi-mode gateway shown includes a gateway connected to the EUHT wireless infrastructure network. The gateway includes a multi-functional baseboard, on which a control chip, flash memory and memory are provided, and a narrowband communication device is connected. The data of the perception layer MEMS sensor is collected through the narrowband communication device, and the data is transmitted to the EUHT wireless infrastructure network. The narrowband communication device includes Bluetooth, ZigBee communication modules and LoRa modules.

[0020] The multifunctional baseboard serves as the main circuit board for the control chip, flash memory and memory, and provides a variety of connection interfaces. It is connected to the LoRa module and EUHT module through the MINI PCI-E interface or the UART interface, and is connected to the Bluetooth and ZigBee communication modules through the double-slot board-to-board connector.

[0021] The MINI PCI-E is an interface based on the PCI-E bus, mainly used for notebooks and digital devices. It uses the popular point-to-point serial connection in the industry. Compared with the shared parallel architecture of PCI and earlier computer buses, each device has its own dedicated connection. The UART (Universal Asynchronous Receiver / Transmitter) is a universal data communication protocol and a general term for asynchronous serial communication ports (serial ports). It converts parallel data into serial data for transmission when sending data, and converts received serial data into parallel data when receiving data. It includes interface standard specifications and bus standard specifications such as RS 232, RS499, RS423, RS422 and RS485.

[0022] The description of the EUHT module shows that there are two types, 1.8G and 5.8G. The EUHT module 1.8G is an authorized frequency band, ultra-high-speed wireless communication technology, suitable for short-distance communication, with fast transmission rate, low latency, and high reliability; it is connected to the multi-function baseboard using the MINIPCI-E interface. The EUHT 5.8G is an unauthorized frequency band, with a faster transmission rate and a wider coverage; it is connected to the multi-function baseboard using an Ethernet interface.

[0023] The control chip adopts MT7268 chip, and the flash memory adopts Flash or SSD solid state hard disk.

[0024] The gateway is also connected to the EG95 module via a USB interface, and the EG95 module can connect to the LTE network. The EG95 is a series of LTE-FDD / WCDMA / GSM wireless communication modules with diversity reception function, supporting LTE-FDD, DC-HSDPA, HSPA+, HSDPA, HSUPA, WCDMA, EDGE and GPRS network data connections, and can provide voice functions for customer special applications.

[0025] The gateway is also connected to an AP module for connecting to wifi. The AP means the HUB in the traditional wired network and is also the most commonly used device when building a small wireless LAN. AP is equivalent to a bridge connecting the wired network and the wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to Ethernet.

[0026] The gateway is also connected to a LAN interface via an adapter, and communication is performed via the LAN interface. Figure 2 The Switch module in the multi-mode gateway is connected to the LAN interface on the backplane of the gateway via an Ethernet cable.

[0027] The ZigBee module, BLE module and multi-mode gateway baseboard are connected through board-to-board connectors, and data is transmitted through UART.

[0028] The working principle of this utility model is as follows: construct a perception-level terminal device serving EUHT wireless basic network communication technology. EUHT's wideband and narrowband communications belong to a closed private network, which is physically isolated from the external network and has a very high security level. The research and development of EUHT communication terminal equipment is based on the wideband and narrowband communication functions of EUHT communication, and the reasonable application of terminal equipment in EUHT technology is realized. For example, gateways and cameras transmit structured data to the cloud through the EUHT 5.8G wireless network, which can be flexibly deployed to reduce the cost of laying pipelines and cables. Based on the lower-layer narrowband communication of the EUHT basic network, the gateway provides narrowband communication protocols such as BLE, iBeacon, ZigBee, LoRaWAN, etc. to communicate with low-power sensors, which can realize M2M communication between devices, thereby reducing network routing resources.

[0029] The multi-mode gateway has certain edge computing capabilities, converting different types, communications, and messages into a unified data format, and correlating and fusing the data from IoT sensors to output structured data to the EUHT network.

[0030] The utility model has the following advantages: EUHT is a government-specific network, the multi-mode gateway connects the IoT narrowband sensor and the EUHT core network at the same time. EUHT technology has a large number of implementation cases in actual application scenarios.
