MEI urban lighting equipment is a controller and monitor for street light cabinets using an independent 4G connection, fully integrated with the MEI Eco ecosystem. The solution allows centralized management of many light cabinets on web and app platforms, suitable for deployment on roads, residential areas, industrial parks and smart cities.

The device supports independent control of 2 lighting lines, each line can be turned on/off separately to optimize energy saving. Operating modes include: manual control at the cabinet, remote forced control via app and automatic control according to a flexible timer schedule based on day or time frame.

The integrated system measures electricity including voltage, current, instantaneous power and energy consumption (kWh). Data is saved locally and synchronized to the server via 4G, ensuring no data loss when the network is lost. The device also warns about overcurrent, load problems, power outages and offline status. Users can track data in tables and charts and export detailed Excel reports to help manage and control electricity costs.

I. General description

MEI urban lighting control device is a specialized street light control and monitoring unit, using connection Standalone 4G LTE, independent of LAN/WiFi infrastructure.

Devices connect directly to the ecosystem MEI Eco Web/App through a secure MQTT platform, allowing centralized management, real-time monitoring and remote control.

Applications

• Urban route

• Residential area, industrial park

• Area without fixed internet

• Distributed smart urban lighting system

II. Control function

1. Control 2 lines independently

• Control 02 separate lighting lines

• Each line has:

  • Separate power relay/contactor output

  • Independent current monitoring

  • Monitor power and energy consumption

2. Operability

• Turn on/off each line individually

• Operating 1 line saves electricity

• Operate 2 lines simultaneously when needed

• Flexible load coordination by region

III. Operating mode

1. Manual mode at the cabinet

• Separate ON/OFF switch for each line

• AUTO / MANUAL mode

• The device still operates normally when 4G connection is lost

2. Remote coercion control

Through MEI Eco:

• Enable/disable each line forcibly

• Record operation log

• User authorization

• Control by group of cabinets

3. Scheduled control

• Configure multiple time frames per day

• Set by day of the week

• Calendars are saved locally on the device

• Does not depend on network connection

IV. Power monitoring

Device with integrated electrical measurement function:

• Voltage (V)

• Current (A)

• Instantaneous power (W)

• Electricity consumption (kWh)

• Power Factor (PF)

Data storage

• Save locally using Industrial Flash

• Periodic synchronization via 4G

• No data loss when signal loss

V. Trouble warning

The device automatically detects:

• Overcurrent

• Voltage drop

• Power outage

• Short load

• The light does not light up when it is turned on

• Lost 4G connection

Warning form

• App

• Web

• SMS

• Warning call (depending on configuration)

VI. Display and reporting

1. Chart format

• Hourly power

• Electricity by day/month

• Compare 2 lines

• Abnormal consumption analysis

2. Table format

• On/off log

• Warning history

• Electricity statistics

• Operating time

3. Export report

• Excel export by day/month/time period

• Content includes:

  • Total kWh

  • Average power

  • Operating time

  • Number of on/off times

  • Incident list

VII. Advantages of independent 4G solution

• No need for fixed internet infrastructure

• Quick installation

• Each cabinet operates independently

• Suitable for long routes

• Easy to expand to large scale

VIII. Benefits brought

• Save 20–40% electricity

• Centralized management of the entire system

• Early detection of problems

• Transparency of consumption data

• Completely remote operation via 4G
