Intelligent transformation of rail networking communication equipment based on Ames DR series

1、 Programme background

The traditional distribution box has a single function and relies on manual meter reading and patrol inspection. It is difficult to give early warning of potential power safety hazards, extensive energy efficiency management, and high operation and maintenance costs. By deploying Ames DR series rail type communication equipment (integrated DTU, power module), without changing the structure of the original distribution box, it can quickly realize the remote acquisition of meter data, power safety monitoring, and cloud based intelligent management, and help the digital upgrade of the distribution system.

2、 Core function module

Smart meter data acquisition

Multi protocol compatibility: connect all kinds of meters (such as Modbus, DL/T645 protocol) through RS485/RS232 interface, and collect voltage, current, power, electricity and other data in real time.

Networked transmission: built-in 4G/NB IoT communication module to upload data to the cloud platform instead of manual meter reading.

Power safety monitoring

Abnormal early warning: monitor faults such as leakage, overload, short circuit, three-phase imbalance, and trigger audible and visual alarm or SMS notification.

Remote power-off: the circuit breaker is linked through the DO interface, and the power can be cut off remotely in case of emergency.

Cloud energy efficiency management

USR Cloud platform: visual display of power load curve, time-based energy consumption statistics, and support APP/PC terminal access.

Energy saving analysis: identify high energy consumption equipment and provide optimization suggestions (such as peak and valley power consumption strategy).

Optimization of equipment operation and maintenance

Self diagnosis function: monitor the working status of DTU and power module, and report automatically in case of failure.

OTA upgrade: remote update of device firmware to reduce on-site maintenance costs.

3、 Technical implementation

Hardware layer: DR series rail mounted equipment: directly installed on the standard guide rail of the distribution box, without the need to modify the box structure.

High integration design: it integrates DTU and power module, saves space, and supports wide temperature operation of -25 ℃~70 ℃.

Transmission layer: 4G/NB IoT wireless transmission, suitable for remote scenes without optical fiber coverage.

Platform layer: USR Cloud provides data storage, analysis and alarm management, and supports API docking with third-party energy management systems.

4、 Deployment advantages

Low cost reconstruction: use the original distribution box structure, only need to install DR series equipment, construction time<30 minutes/set. The track type design is wiring free, reducing the installation complexity.

High reliability: industrial protection (IP30), anti electromagnetic interference, adapt to the harsh environment in the distribution box.

Flexible expansion: support user-defined communication protocol, compatible with old and new meters and intelligent circuit breakers.

5、 Application scenarios

Commercial buildings: Real time monitoring of tenants' power consumption to prevent private load connection.

Industrial park: measure energy consumption by production line and optimize production scheduling.

Public facilities: remote management and fault location of street lamp distribution box.

Photovoltaic power station: two-way monitoring of power generation and consumption.

6、 Expected benefits

Safety improvement: reduce the risk of electrical fire, and increase the fault response speed by 80%.

Energy saving and consumption reduction: the comprehensive energy consumption is reduced by 10%~15% by optimizing power consumption through load analysis.

Efficiency improvement of operation and maintenance: the cost of manual meter reading is reduced by 90%, and the efficiency of patrol inspection is increased by 50%.

7、 Case reference

After the transformation of an industrial park: save about 250000 yuan of electricity cost annually;

The overload fault processing time is shortened from 2 hours to 10 minutes.
