Intelligent Street Lighting with ZIGBEE Protocol
Zuck
Introduction
Intelligent street lighting has been increasingly sought after in the market since 2017 and even earlier. Many requests have been made for a smart control system or intelligent control system to be used in LED street lighting. This advanced technology greatly assists electricians and municipal administrators in efficiently managing the country’s LED luminaires. By monitoring the status of each lamp through a web-based platform, operators can swiftly identify any failures and promptly schedule maintenance and repairs. The comprehensive status of all lamps is conveniently displayed on the intuitive web interface.
Components of Intelligent Street Lighting
ZIGBEE protocol is one of the most frequently adopted wireless protocols in electronic products and devices and household appliances(Smart devices), which make those units with ZIGBEE modules built-in and communicate with each other. With a gateway or so-called “concentrator” we can gather all useful information and current status of devices to a purpose of monitoring and repairing. The status of information is uploaded to the cloud.
When it comes to LED street lighting projects or tender works it would be almost same operating style in a proportion of bidding documents of requirements stating they need sort of smart control systems.
“Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create personal area networks with small, low-power digital radios, such as for home automation, medical device data collection, and other low-power low-bandwidth needs, designed for small-scale projects which need wireless connection. Hence, Zigbee is a low-power, low data rate, and close proximity (i.e., personal area) wireless ad hoc network.”

Generally as experiences a complete suite set of LED street lighting system ZIGBEE protocol based includes basically LED street lights with NEMA 7in receptacle on ANSI B136.1 (Often simply called “Socket”), Lighting controller, gateway and web end interface. It will be so complicated when we are reading the technical explanations and professional articles by experts of some famous electricians from head huge brand of companies of the world. However it is appeared to be easier when we get some real fixtures and materials in hand. After testing guided by the LED lighting manufacturer, you will understand that way much better.
LED Street Luminaire with NEMA 7 pin socket
Lamp with a socket
This is ZGSM RIFLE Series intelligent street lighting and a little bit difference is the small round black socket on the regular back of body. In some tendering works they state it as “Smart Ready” in their bidding documents which means they will use this configuration for the upcoming applications of remote control in the near future or long run.
Lamp with a lighting controller
It is very important for us to pay attention that we need a extra Short Cap before installing a real lighting controller. Without a Short Cap, the luminaire will not work. If we plug in the lighting controller on this socket, the lamp becomes a “smart device” then.
Short Cap

Rated voltage: 0-480V
Rated load: 15A
Shell: Anti-ultraviolet and impact-resistant PP

Gateway
ZGSM11-GW-3 is a kind of Internet of Things wireless communication gateway, which uses the public network wireless network + small wireless network to provide users with the function of eliminating the need of field wiring and wireless long-distance data transmission.
The product uses high-performance industrial 32-bit processor and industrial-grade wireless communication module, while providing a serial port (RS232 / RS485), four Ethernet LAN ports, an Ethernet WAN port, and supports WIFI AP / Repeater / STA, so it can be connected to serial devices, Ethernet devices and WIFI devices at the same time, which provides a perfect platform for IoT applications. It can be widely used in industries such as self-service terminal industry, smart grid, intelligent transportation, Automation, intelligent building, fire protection, environmental protection, smart medical treatment, smart lighting, smart agriculture and coal mines, oil and other occasions.
- Put WIFI, 4G and other wireless antennas properly connected.
- 4G / Ethernet cable (optional) to make gateway access to internet.
- The gateway connected to the power supply, recommended DC12V 2A power.
Figure 7 – Gateway
Other connection port optional
- COM connection: 485 A + B-, and customer 485 interface A, B feet orthogonal connection. 232 interface, RX, TX, GND, and customer 232 serial port RX, TX anti-cross connection, GND direct connection.
- LAN port connects computer or industrial network port equipment, serial port connects industrial serial devices, WAN port connects to switch and other network equipment.
Tips: We will also need such a box to load the gateway with its own power supply device, inner wiring and positions for antennas. It provides enough room for the device and on the other hand protect the device from water, dust and immoral human strikes. You can order this housing from us or completely design it by your team.
Web end interface – Software Platform
ZGSM intelligent lighting management & control system requires conducting the platform operations with Google Chrome. Enter the login website, click “Enter” to enter the login interface. Enter the account, password and identifying code (case insensitive) provided by the supplier and click “Login”. When the status of “Keep Password” is selected, then the user name and password entered this time will be saved. When the system starts next time, it will login automatically with the saved user name and password. (As shown in the following figure)
After we get an available ID with password given by the lighting supplier, we can log in this system and start to monitor the intelligent street lightings that we installed on local sites. Such as brightness of percentage, dimming of lights, on/off and most importantly the strategy settings. Here I have an example of strategy setting:
| SL No. | Name of Month | stage 1 | stage 2 | stage 3 | stage 4 (Day time) |
| 1 | February to April | 100% from 18:10 to 1:00 | 50% from 1:00 to 3:00 | 80% from 3:00 to 6:00 | off line from 6:00 to 18:10 |
| 2 | May to September | 100% from 18:35 to 1:00 | 50% from 1:00 to 3:00 | 80% from 3:00 to 5:20 | off line from 5:20 to 18:35 |
| 3 | October to January | 100% from 17:20 to 1:00 | 50% from 1:00 to 3:00 | 80% from 3:00 to 6:20 | off line from 6:20 to 17:20 |
