Smart City Transmission Solution

Protecting your data transfer from source to end point

Smart cities utilize information and communication technologies to sense, analyze and integrate key information from the core systems of city operations, so as to respond intelligently to the different needs of people’s livelihoods, environmental protection, public safety, city services and industrial and commercial activities. Its essence is to realize intelligent city management and operation through advanced information technology, thereby creating a better life for citizens and promoting balanced and sustainable urban development.

The Pain Pints Analysis of Intelligent City Communication

To adapt to the high temperature and hot and humid environment of urban intersections, industrial Ethernet switches must design according to wide temperature and moisture-proof; Operating temperature: -40～80℃ Storage temperature: -40～85℃, storage humidity: 0%～95%, no condensation.
The harsh environment of urban intersection cabinets requires industrial Ethernet switches with strong dustproof, anti-vibration, anti-electromagnetic interference, long meantime without failure, etc.
The equipment must be compact and easy to be installed in the intersection cabinet.
To ensure the reliability of communication, a Gigabit or 100 Gigabit redundant ring network with a fast self-healing function is required. When the communication network fails, it can automatically and smoothly switch to the redundant backup line, with a self-healing time of less than 20ms.
To ensure the data security of remote monitoring, the industrial Ethernet switch needs to have comprehensive network security settings.

The City Intelligent Transportation Communication Solution.

Intelligent transportation is a service system based on modern electronic information technology-oriented transportation. It collects, monitors, and analyzes road traffic information and traffic-related service information and realizes reasonable control and decision-making. A typical intelligent transportation system contains a signal control system, electronic police system, speed detection system, closed-circuit television monitoring system, traffic event detection system, traffic guidance system, power supply, lightning protection system, GPS vehicle positioning system, traffic communication system, and other subsystems. The traffic communication system is the most critical support layer of the intelligent transportation system, providing an effective, fast and accurate information transmission channel for public security traffic command and dispatch.

HoweVis Technology is committed to building a real-time, reliable, and robust intelligent network for intelligent traffic information and extensive data collection. We have developed a variety of highly reliable, industrial-grade, and brilliant communication products to meet the communication needs of the transportation industry. We provide professional communication solutions to guarantee the high-speed passage of massive information and comprehensively open the door of intelligent communication.

Intelligent Pipe Corridor Communication Program

Communication System Network of the Pipeline Corridor

According to the technical specifications of the integrated pipe corridor, the integrated pipe corridor is designed with a fire partition every 200 meters, and firewalls and fire doors are set. A comprehensive pipe corridor may be divided into a pipeline compartment, electric power compartment, and gas compartment. The choice of underground integrated pipe corridor communication scheme first needs to consider the demand of its business bandwidth, that is, the choice of how much bandwidth to build the industrial ring network. Its bandwidth must meet the existing business bearing while meeting the subsequent expansion of business.

With 200m as a partition node, the business with the most significant bandwidth demand and the number of ports required are as follows.

The table shows that the single-compartment, double-compartment, and three-compartment service port demands are 11, 18, and 25, respectively, with relatively significant differences in quantity and rather large differences in corresponding equipment port patterns. Therefore, this program will be equipped with the corresponding form of equipment models for different cabin types and two fire partitions that a weak power room is responsible for. Each invalid power room is configured with two sets of equipment or placed separately in the corridor, and the ports and bandwidth of each weak power room are twice that of the fire partition. See the equipment configuration list for specific configurations.

In addition, the bandwidth requirements of different compartment types are other, and the compartment type and length of the corridor have to be taken into account when analyzing the bandwidth of a single section of the gallery.

Comprehensive consideration of the rest of the business needs, video surveillance services in the initial design, and single-loop service utilization are not easy to be too high initially. Initially, the bandwidth of the video surveillance class is suitable for design in less than 50% utilization, assuming a single gigabit ring business configuration of 500M. According to the previous calculation, a single 200-meter node needs video surveillance services in 24M, and then a 1000M ring can contain 20 switches, that is, 4km corridor configuration 1 1000M ring.

Comprehensive Pipeline Corridor Communication System Topology

Although the underground comprehensive pipeline corridor cities across the country are starting one after another, the size of each regional project varies, and the construction of sub-sections and the length of the corridor to be built are different. Therefore, the choice of communication scheme must also adapt to the requirements of various construction scales, meet the existing construction scale requirements, and adjust to the subsequent expansion needs.
