not have a traffic monitoring controller. The used
system identified three types of fault which are
amount of the LED brightness, electrical outage, and
physical defect. The system composed a message to
be sent to control room. The used system has same
issues the GSM-based system Rajput et al. had.
Another system (Azura et al., 2013), based on
sequence-fuzzy controller, was used to check the
LED brightness level. The idea is that for each
sequence of traffic light junction and for each pole,
only one of the LEDs will be activated while the
other LEDs will not be activated. If the LED did not
show the correct sequence (Green, Orange, Red), the
LED is diagnosed as faulty and the system send the
notification to control centre to make action. The
used solution was limited to traffic lights only and
cannot be implemented in other fault light detection
systems.
In (Saleem et al., 2015), a street light monitoring
and control system was designed to minimize the
time that a workman spends in searching and
locating the fault light. The light sensors were placed
in all street lights’ circuit to switch on and off
automatically. Once the lights are switched on,
current sensors placed at every light pole were
responsible to send light’s status to a centralized
system using GSM module attached with the circuit.
The proposed system was efficient in outdoor fault
light detection. However, the system was not
economically feasible for indoor big facilities with
huge number of light bulbs. Also, not all light bulbs
come with circuits to make the solution feasible.
In (Kuo-Hsiung et al., 2016), a G3-PLC-based
solution for intelligent street lamp monitoring and
energy management was proposed. The main
purpose of this system was to detect street lamp
issues such as the light is off or missing a wire since
it took a long time to solve it. This system had
weather resistance, 24-hour automatic monitoring,
wide monitoring range, and automatic routing
capability to detect every lamp’s status such as
power consumption, on-off state, and temperature. It
had the features of street lamp energy-saving control
and multiple alarm modes for users to choose. The
management system comprised of street lamps,
street lamp monitoring server, and street lamp
monitoring client-side. If a street lamp had an open
maintenance hole, electricity leak, or did not light, a
warning was sent via power lines to the G3-PLC
host, concentrator, and the server via GPRS or an
SMS short message. The used system was not
economically feasible due to using the GPRS and
SMS messaging. On the other hand, this system
cannot be implemented in indoor places due to the
limited ability of this technique to identify faulty
lights to a small distance accuracy.
In (Sumathi et al., 2017), an arm-based street
lighting system with fault detection was designed to
identify street lamps status where a GSM module
was used to send messages. Each street lamp was
monitored using fault detection circuit. In case of
any faulty lamp, the circuit sends the information to
the controller which in turn notifies to corresponding
maintenance department using the GSM module. A
light dependent resistor was attached close to the
street lights to detect any bulb faulty condition. The
light dependent resistor (LDR) offered a high
resistance value thereby making the circuit open. An
arm processor checks for this condition only when
the corresponding street light is switched ON. When
this condition is triggered, the arm processor sends a
message to the control room using the GSM modem
connected to the processor and thereby had a good
management system. One of the main weaknesses of
this system is being expensive.
In summary, all the previously discussed
proposed systems did not target indoor areas. Also,
they require to replace the current used lighting
system with the proposed system which takes time
and costly and thus hinder the adoption of that
system. Table 1 shows a comparison between
different fault light detection systems. The
comparison is done based on reliability, cost,
maintenance cost, lifespan, and indoor suitability.
