Resource Inventory

Mounting

Engineering structure to which the luminaire is attached. For example: street light mast (pole), guy wire or ceiling / wall bracket.

For each mounting, the maximum number of luminaires that can be installed simultaneously is indicated. The place for mounting the luminaire on a mounting is called a horn.

The mounting is connected to the electrical network through SLCC (usually in European countries) in this case, for the mounting you can specify from which SLCC it is powered and to which phase it is connected.

Segment

Logical object for combining mountings with common lighting rules, for fine-tuning lighting rules. In most cases, one segment is sufficient, which unites all the pillars of the project. Each segment has a type from the directory: courtyard, historic center, park, highway, etc. At the segment type level, the lighting policy is defined (see below).

luminaire

Uncontrolled- a luminaire without a constructive possibility of installing the head.

Controlled (Smart) - as a rule, a LED luminaire equipped with a head.

Smart Ready - a luminaire that has the ability to install a head without structural changes, but at present it works as a conventional uncontrolled luminaire.

Head

Head (Head Unit) is an electronic device that makes the luminaire “smart”. This is a microcomputer with a radio modem and a set of sensors, which ensures the reception and execution of commands, as well as monitoring the operability of the luminaire. It can be built-in or external (NEMA, ZHAGA) execution.

In the case of built-in design, the possibility of prompt replacement of the head, without replacing the luminaire, depends on the design of the latter.

SLCC

SLCC (Sreet Lighting Control Cabinet) is a set of connected electronic and electrical components protected from external factors by a metal or plastic box - a cabinet (one of the sides of the box is a door). Depending on the requirements of the project, the composition of the SLCC may differ. The SLCC includes an electric cable from a low voltage transformer substation, and [1..N] outgoing lines go out in the direction of street lighting mounting points.

SLCC controller

An electronic device that provides the “cleverness” of SLCC. This is an industrial microcomputer that provides the reception and execution of commands, as well as monitoring the performance of the SLCC components. Different controller models can be used depending on the project requirement.

Electricity meter

An electronic device installed in SLCC, which measures the characteristics of electricity and registers the collected readings in its own internal memory. Saved and current values of characteristics can be read by the SLCC controller. The list of recorded characteristics depends on the meter model.

SLCC Components

SLCC components fall into two categories:

• uncontrolled - sensors
• controlled - a device that can change its characteristics (status) by a command received from the controller. As a rule, it is also a sensor.

Cascade

Power on / off technology on lines outgoing from SLCC, in the absence of own SLCC controller.

Power point

Transformer station designed to increase or decrease the voltage in the AC network and for the distribution of electricity.

Lighting Control

Radio Gateway

The radio gateway provides traffic exchange between the IP network and the luminaire heads.

Radio gateway is a microcomputer with GPRS / 3G modem (uplink) and radio modem (downlink) for organizing a mesh network in the 868Mhz range, packed in a sealed plastic case. Installed on a mounting. Requires 220 V.

Soft-radio gateway is the implementation of the functionality of a radio gateway in the form of a program. A radio modem is connected to the controller installed in the SLCC, and the program code that implements the logic for transmitting traffic from IP to radio and vice versa is installed on the controller.

Several radio gateways operating on the same frequency range form a radio network, in which they can act as the main or backup device.

Radio Network

The way of organizing the interaction between the Luminaire head and the System using a digital radio signal. One project usually has several radio networks. Radio gateways are the backbone of a radio network and operate in the same frequency sub-band within the same radio network.

The number of radio networks and the number of radio gateways are determined at the design stage.

Mesh Network

A method of organizing a digital radio network, when each device is a receiver, retransmits the received packet further, if the packet was not addressed to this device. Thus, the transmission of information over long distances is ensured, with a low power of the receiver / transmitter that does not require permission.

Tag

A text label that can be assigned to a luminaire. Multiple labels can be assigned to one luminaire.

SIM card

Contact smart card with its own processor, capable of registering with the mobile (radio) network

Lighting Profile

Automatic dimming rules at night. Each lighting profile has a name. The system supports an unlimited number of lighting profiles, but on any day of the year, a luminaire can only have one profile.

Lighting Policy

Rules for automatically assigning profiles to luminaires under one identifier. The system supports an unlimited number of policies, but each segment type refers to only one policy.

Region

A logical object enabling support of different on/off annual schedules by the cabinets. The territory within which the single sunrise / sunset / dusk time is recognized for all SLCCs located in this region.

For example, with centralized lighting control of a road stretched from west to east, the difference between sunrise / sunset at the extreme points of the road can be up to 45 minutes. The division into regions allows you to have individual schedules for the rise / fall and on / off of the contactors.

Astro Calendar

A reference book containing the time of sunrise and sunset in a given region for each day of the year, as well as the time when the power is turned on and off by the SLCC contactors.

Network Gateway

A software module that provides hiding the features of the implementation of protocols for interaction with equipment: controllers, meters, radio gateways and heads. On the one hand, the module provides a unified API with which the Management Console module interacts, on the other hand, it implements the required API for working with devices. The presence of a Network Gateway (NG) makes it possible to service equipment from different manufacturers within one system.

Several NGs running on different servers, if necessary, provide horizontal scaling.

Metrics and Measurements

Metric is a snapshot of the state of performance indicators or sensors of a device at a point in time. Electronic devices involved in street lighting regularly record their states at a point in time in their original form or after small calculations in their own memory. For example: once a second, the head writes into its own RAM the current power consumption by the luminaire driver, and also calculates the time in seconds that has passed since the power was supplied to the head.

From the point of view of data volumes, bandwidth and cost of 3G traffic, it is not rational to transmit to the center all data recorded by devices at every unit of time, therefore, metrics of different types and from different devices are delivered at different intervals to meet the project requirements. For example: the instantaneous power of the electricity meter once every 2 minutes, all other registers of the meter once every 60 minutes, or if the instantaneous power has increased by 30%.

Head metrics

The composition of the head metrics depends on the manufacturer, model and activated options of the device.

For example:

• temperature (microprocessor);
• illumination level (if there is a sensor);
• GPS coordinates (if there is a sensor);
• Current dimming level (0..100);
• Power level of the radio module (milliwatts);
• The signal level of the radio module (decibels);
• Channel number (frequency sub-band);
• Current power consumption by the driver (if there is a current sensor);
• Characteristics of electrical energy (in the presence of an electricity meter): Voltage, current, active power, reactive power, active energy, reactive energy, cosine phi, etc.

Radio Gateway Metrics

The composition of the radio gateway metrics depends on the manufacturer and model. In particular, the following values are expected to be provided:

• unique identificator;
• code of the radio network to which the radio gateway belongs;
• time of the last power supply;
• sign of the main or backup radio gateway within the network;
• GPS coordinates (if available).

Using the metrics of radio gateways, it is possible to determine the power on / off time on the supports in the absence of a SLCC with electricity meters in the project.

Energy meter measurements

Measured readings vary by manufacturer, model, and supported options.

The following types of indications are supported:

• instant;
• daily allowance;
• monthly (billing).

Metrics of SLCC sensors states

The composition of the registered states depends on the component composition of the SLCC. If there is a sufficient number of digital inputs and outputs, the SLCC controller supports:

• door opening sensor;
• position of the switch for remote local control of contactors;
• the status of the input terminal;
• statuses of outgoing machines;
• statuses of contactors;
• battery charge level (if available).

Instantaneous power consumption

Every N seconds, the current active power is read from each electricity meter and stored in the system.
