Background
With the rapid development of industrial automation, urban residential construction, and rural town development, the number of water, electricity, gas, and heat meters is increasing rapidly, making meter reading and measurement increasingly complex. Traditional meter reading methods involve manual on-site collection of usage, voltage, and power data periodically, followed by data processing and transmission back to the monitoring center. This method suffers from numerous drawbacks, including low efficiency, high costs, long data update cycles, errors and omissions, and security risks associated with intrusion.
Now, remote meter reading systems effectively solve the shortcomings of traditional manual meter reading, improving work efficiency, reducing labor costs, and decreasing management and maintenance costs.
Client Requirements
- Data Collection
Remote, periodic, and automatic collection of cumulative usage, instantaneous flow, and equipment status (e.g., valve status, battery voltage) data from water, electricity, gas, and heat meters for residential and commercial users.
- Operation and Maintenance Management
Support for remote valve control, tripping and closing functions, and remote parameter configuration and firmware upgrades for concentrators and meters, enabling full life-cycle management of the equipment.
- Visual Analysis
The platform needs to display usage data across multiple dimensions, including region, time, and user type, generating daily, monthly, and yearly usage reports, expense invoices, and production-sales difference analysis reports, and supporting historical data query and comparative analysis.
Technical Solution
The remote meter reading system includes meters, a data acquisition module (IOTRouter ET2100), a data concentrator (IOTRouter EG2000), and a data center.
The ET2100 data acquisition module connects to the meters via RS485 to collect data and control valve operations such as tripping and closing. It transmits the collected data to the EG2000 data concentrator via LoRa spread spectrum wireless communication.
The EG2000 concentrator stores the collected data daily and periodically transmits it to the data center via 4G network communication for administrator analysis and querying.
EG2000 Data Concentrator
The EG2000 is an industrial-grade LoRa edge gateway device that enables data uploading to the cloud and remote networking. It adopts the new LoRa spread spectrum technology, with a communication distance of up to 8KM and a maximum transmit power of 30dBm. It can be used with the ET2100 terminal device, connecting to serial devices via an RS485 interface to achieve data transmission from the device to the cloud.
