This product solution is based on a testing that was carried out by one of our partners who needed to precisely synchronize OROS' OR35 noise analyzers over the Ethernet network. These noise analyzers were located in different locations; therefore, our partner aimed to seek a way to have these analyzers to start and stop at the same time. After receiving the needs of our partner and having several discussions with our partner,
Highways and railways in mountainous areas go through tunnels very often. For safety concerns, tunnels not only have to provide systems like fire protection, ventilation, traffic guidance, communications and lighting, but also are able to send real-time tunnel monitoring data or messages automatically to networking personnel in the remote-control center so that immediate actions can be taken when systems are broken or accidents occur in the tunnel.
With rapid development of new technologies and the increasing rise of urbanization, the demands of transforming
transportation systems into technologically advanced vehicles are growing rapidly. Recently, CTC Union has several
successful cases of adopting "smart bus" systems for public mass transportation. For example, buses or minibuses are
being equipped with multiple networking devices such as 4G WiFi router, passenger information display, surveillance
cameras, electronic ticketing, GPS tracking, etc.
The demands for intelligent rail networks, such as high-speed railways, subways, commuter trains and light rail are at a
record high due to rapid urbanization. However, the railway environment is notoriously characterized by a harsh and
tough working environment, where constant shock, vibration, dust, temperature and humidity variations, along with
electrical disturbances are common and inevitable. These environmental factors pose foreseeable challenges to
network operators which include the following:
In recent years, thanks to the rapid development of networking devices, high performance and high-definition IP
cameras are installed in every corner in metropolitan areas with ease and simplicity. By analyzing real-time or recorded
video images received, the government can fight against violence or any sort of terrorist attacks in a more efficient and
effective way with less cost and manpower supports. However, when it comes to highway surveillance implementation,
the situation becomes more complex. Unlike surveillance implementation in urban areas, highway runs across many
cities. Thus, frequent policeman patrolling is not realistic since it needs more manpower supports and is not efficient
enough when an emergent event occurs. Before setting up a successful highway surveillance implementation, there are
several challenging factors we need to take into account.
In a city or town, intersections are usually the busiest places where minor or severe road accidents occur
frequently. To tackle this issue, city governments are increasingly installing various monitoring systems at
intersections so as to effectively reduce traffic accidents and at the same time to strengthen road safety.
Intersection monitoring systems including the use of PoE IP surveillance cameras, traffic flow sensors and
traffic controllers, are able to record traffic images, count the number of passing cars and record car speed
or to be reviewed for accident footage. However, these end devices are incapable of Ethernet
transmissions. Therefore, they need to be used with PoE-supported Ethernet Switches so that a secure
intersection monitoring solution can be built up. When choosing the right intersection monitoring devices,
there are several challenges that need to be considered.
In many countries, people rely heavily on trains or high-speed trains to travel between cities or countries. Owing to high
usage rate of train system, some countries are updating train infrastructure to electrification system so as to deliver
efficient, faster and environmentally-friendly rail services to passengers. Besides, the network system is also updated
from non-IP based to IP-based allowing greater integration and operation flexibility.
Along with the rapid development of technology, factory plants have been transformed to ones that are equipped with
automotive production system so that equipment efficiency can be greatly enhanced and operational costs can be
reduced to minimum. The critical role that leads to this change is the prevalent use of Ethernet-based networks in
connecting isolated networks across the plant to communicate each other without difficulties and enabling decision-makers
to launch product plans faster than before.
Recently, manual highway toll collection system has been replaced by electronic or automatic one thanks to the rapid
development of various technologies. Compared with the manual highway toll collection system, electronic highway toll
collection system allows road users to keep driving without stopping when entering the toll lane. Therefore, the total travelling
time can be shortened and air pollution can be decreased. Moreover, the decrease of human intervention at the toll
lane can also reduce human error and increase efficiency when collecting tolls.
