Description

Technical Field

[0001] This invention relates to the technical field of smart meters and power Internet of Things (IoT) gateway devices, specifically to a dual-mode deployment, dual-uplink redundancy integrated gateway meter. Background Technology Currently, most power IoT metering systems on the market adopt a "separate deployment of electricity meter + independent gateway" solution. On-site construction requires separate installation of the electricity meter and communication gateway, resulting in complex wiring, high hardware procurement and labor installation costs, and significant challenges in subsequent equipment maintenance. Furthermore, existing products have numerous technical shortcomings: 1. Limited communication methods: Most only support a single type of uplink network, such as 4G or Ethernet. When the network signal is poor on site, communication interruption and meter reading failure are very likely to occur. There are no redundant backup links. 2. Limited deployment scenarios: Downlink communication only supports a single wired RS485 network, which requires on-site cabling. It cannot be adapted to scattered scenarios such as dormitories and scattered shops where cabling is inconvenient, and the equipment has poor versatility. 3. Data loss due to network outage: The existing gateway does not have local time-sharing offline storage capability. After the external network is disconnected, the electricity consumption data of the external electricity meters on site cannot be retained. After the network is restored, historical electricity consumption data cannot be retrieved, resulting in missing metering data and causing disputes over electricity bill reconciliation. 4. Functions cannot be reused: Gateways can only forward data and cannot be used independently as electricity meters; ordinary smart meters do not have gateway networking capabilities. The functions of the two types of devices are disconnected and cannot be flexibly adapted to different field conditions. In summary, existing split-type power metering devices suffer from defects such as low integration, low communication fault tolerance, poor scenario adaptability, data loss during network outages, and limited functionality. The industry urgently needs an integrated gateway meter that is integrated, has dual-link redundancy, supports dual-mode deployment, and has offline data caching capabilities. Summary of the Invention Purpose of the invention: To address the shortcomings of existing technologies, this invention provides a dual-mode deployment dual-uplink redundancy integrated gateway meter, solving the technical problems of high cost of separate installation of traditional equipment, easy network outage due to lack of communication link backup, single deployment method, loss of metering data during network outage, and inability to reuse equipment functions. Technical solution Technical Solution: To achieve the above objectives, the present invention adopts the following technical solution: A dual-mode deployment dual-uplink redundant integrated gateway meter, comprising a meter metering module, a gateway main control module, a dual uplink communication module, a dual downlink communication module, and a local offline storage module. The electricity metering module is responsible for collecting and measuring basic electrical energy parameters. It can operate independently of the gateway, achieving dual functionality. The dual uplink communication module integrates 4G and Ethernet dual links, operates with hot backup, and automatically and seamlessly switches to ensure that uplink communication is never interrupted. The dual downlink communication module is compatible with both Bluetooth wireless and RS485 wired communication methods, and is suitable for both distributed, wire-free scenarios and centralized wiring scenarios in power distribution cabinets, respectively. The local offline storage module stores time-of-use power consumption data on an hourly basis, ensuring that data is not lost during network outages and is automatically retransmitted when the network is restored. Beneficial effects Beneficial effects: Compared with the prior art, the present invention has the following core beneficial effects: 1. Integrated hardware, dual-use: Integrates the functions of electricity meter and gateway, eliminating the need for an external independent gateway. It can switch between pure electricity meter mode and gateway networking mode as needed, significantly reducing hardware procurement and construction costs. 2. Dual uplink redundancy backup: 4G+Ethernet hot backup switching, no service interruption, no data packet loss, suitable for complex network environments such as construction sites and old industrial parks; 3. Dual-mode downlink global compatibility: It supports both Bluetooth wireless distributed deployment and RS485 wired centralized deployment, fully covering various power metering sites and greatly improving the equipment's versatility; 4. Offline time-sharing data caching: Automatically stores electricity consumption data by the hour after network outage, ensuring no data loss during power outages and automatic batch retransmission when the network is restored, completely solving the pain point of missing metering data during network outages; 5. Unified management and control of multiple terminals: It can simultaneously connect to multiple IoT terminals such as electricity meters, water meters, and smart door locks, expanding the comprehensive management and control capabilities of power metering equipment.

The gateway main control module is connected to the metering module, the communication module, and the local storage module respectively.
