Market interpretation
According to the classification method in the industry, the LED traffic display mainly includes two categories: passenger information display and highway display. Among them, the passenger information display mainly includes stations, subways, airports, terminals, bus stations and other applications, while the highway display includes traffic guidance screens.
The LED traffic display screen is mainly installed at urban traffic-related road intersections, highways and public places. It is used for traffic information release and urban traffic information induction. It prompts the driver for current road traffic information, such as construction in front, location of the accident, Warning signs such as strong winds and dense fog; can also display simple graphics, speed limit values, etc., so that drivers can better grasp the current road conditions, avoid traffic jams, and reduce traffic accidents. It mainly grasps the real-time traffic condition of the urban road network through the city's traffic management system, and achieves the purpose of optimizing the urban traffic flow through the means of induction.
The scenery is good here. The LED traffic display market has strong demand.
LED traffic display adopts high-brightness LED lighting tube as display material, with high brightness, rich display information, flexible control methods, remote setting and updating, relatively short viewing time, and obvious guidance for drivers who are unfamiliar with road conditions. Advantages, suitable for dense roads in urban roads and highway main trunk lines. Among them, LED small variable intelligence board can display text information in time according to the instructions of traffic, weather and command and dispatch department, such as construction site, cautious driving, safety, strong wind, dense fog and other warning signs and simple graphics; large variable intelligence The board is remotely controlled by the monitoring center computer through the integrated communication network, transmitting and displaying various graphic and text information, promptly releasing different road conditions and various types of traffic information of different road sections to the driver, and propagating traffic regulations and traffic knowledge, thereby effectively Channel traffic and promote driving safety.
In today's transportation sector, LED displays have become an indispensable new darling. Whether in the country or abroad, whether in the downtown or in the suburbs, it seems to have evolved into the "where there is a road, where there is a LED traffic display sign".
In the field of LED traffic display, the market prospect is very large, mainly due to its special application. The development of the national economy, the expansion and improvement of the city, therefore, the rich places should popularize the LED traffic display signs, and the places where there is no money should also promote the LED display signs. In short, the LED display field can almost be said to be "summer no. There is no cold season in the hot season." In addition, with the improvement of people's living standards, the number of private cars will increase substantially. The traffic congestion of urban bustling roads will not only appear in first-tier cities, but will gradually spread to second- and third-tier cities. At the same time, there is no traffic guidance at the forks of urban suburbs or some secondary roads, resulting in frequent traffic accidents, complaints from vehicle pedestrians, and timely guidance from the government, which will surely drive the vigorous development of LED traffic display products.
Double test of capital and technology
Although the LED traffic display market demand is strong, and the competitiveness is far less than the conventional LED display, there are not many companies that can do well in the traffic screen field. "The circle of traffic is very small, doing a bad screen, doing a bad product can make you famous." Some insiders commented.
For an LED display manufacturer, in order to enter the transportation field, you must first have a strong financial support group and technical backing. Due to the nature of the traffic screen, a transportation project usually takes several months or even a few years. The manufacturing company must track the project from the beginning of the project to the installation and maintenance and the acceptance of the later period. After a series of projects are completed, it is possible to receive the due. Payment. Therefore, even though the LED traffic display has a slightly higher profit margin than the general display, there are still a large number of companies that are not daring to enter.
Secondly, due to the special location of the LED traffic screen installation, such as the traffic-inducing screen installed on the expressway, the uninterrupted work throughout the year, no matter how bad the external environment can not stop the information release, even the worse the weather, the content is more important. This puts requirements and challenges on the quality of the LED display itself. And a highway usually has a large number of displays installed. Once quality problems occur, the difficulty and cost of repairs will be amazing. "There is almost no problem, because the highway display repair involves major issues such as road closures, and the cost is amazing." Some companies lamented.
LED traffic display products are display equipments for field work, and must face a variety of severe outdoor environments such as extreme heat, extreme cold, wind, sun, rain, etc. LED traffic display manufacturers must fully consider these The real environment test, the selection of the material of the product to the final product test, a series of supply and demand steps must be strictly controlled. Among them, the reliability and advancement of the control system is particularly important. "If a company wants to enter the field of LED traffic screens, there are not a dozen people who specialize in system research and development are incompetent, and it is impossible to achieve success." Zhou Xu, general manager of Shenzhen Han's Yuanheng Traffic Display Business Unit, said. "Other components can be purchased from the supplier, but the control system must be done by itself, because no control system manufacturer specifically supports the different requirements of different types of traffic screens, so the control system of the LED traffic display is Mastered in the hands of manufacturers." There are many well-known large enterprises that dominate the LED full-color display field, but they have no support for key technologies after entering the traffic screen field.
The double test of capital and technology makes the entry threshold of LED traffic display higher. At present, the more well-known traffic screen enterprises on the market include Shanghai Sansi (known for its dense channel layout throughout the country), Beijing Stone (professional and qualified transportation system solutions), and Dazu Yuanheng. In addition, there are some LED display manufacturers that have certain advantages in the local area. Most LED traffic display companies can only be counted as screen manufacturing companies, and some are simply providers of traffic information screens.
Industry problem analysis: product quality is staggered
Some people say that the LED traffic display market demand is strong, and the number of enterprises is limited, and the basic pattern has been determined, then what are the areas that need to be improved and improved in this widely optimistic industry?
On the one hand, the quality of LED traffic display products is uneven. Many low-end LED traffic screen manufacturers have to participate in the competition at a low price in order to gain a part of the market share, resulting in poor quality of display products for manufacturing. For example, some LED traffic display screens on the road are not properly set, and the sun is too bright to be seen during the day. The light is too bright and glaring at night. The traffic induction effect of such products is not satisfactory, and the original advantages of the LED traffic display signs cannot be fully realized. Moreover, it is easy to accelerate the attenuation of the display itself, resulting in waste of energy.
On the other hand, the standards for traffic communication protocols are missing. This problem is the most embarrassing and urgent problem in the current LED traffic display industry. In order for the various subsystems of the transportation system to operate in a coordinated and efficient manner, it is necessary to establish an efficient communication network system to achieve heavy and close communication links within the system. The informationization of transportation is an important part of the Intelligent Transportation System (ITS). China's current communication protocol standards for intelligent transportation are still in the process of formulation. If unified, open and sustainable communication standards are not established in time, it will bring waste, such as investment, and the systems cannot be coupled. Coordinated operations and other issues.
With the development of urbanization, LED traffic display screens are widely used in all parts of the country. Due to the different needs of LED traffic display installations and the system integrators selected by the purchasing owners, the requirements for LED display screens are different. the same. For manufacturing companies, it is not particularly difficult to make changes in the appearance of screen size, pixels, etc., but the most troublesome is the inconsistent communication protocol between the various places, the chaotic communication protocol for the entire traffic display market. All set obstacles.
At present, Shanghai Sansi has been able to be compatible with communication protocols across the country with years of technical accumulation and engineering project experience. This is very valuable in the field of LED traffic display, and it is also difficult for other companies to look back. Foreign countries have standardized operations on urban road traffic communication protocol standards. For example, the NTCIP protocol applied in the United States and other places can easily unify local standards, which is worth learning from.
The standardization of traffic agreements is closely related to system integrators and display manufacturers. Therefore, the establishment of national-level unified standards will contribute to the development of the LED traffic display industry.
Research on future development trends: intelligence and standardization are the trend
With the advancement of LED display product technology and the establishment of industry standard specifications, various problems of LED traffic display will be gradually solved. In the future, LED traffic display will develop in the direction of intelligence and standardization.
Intelligentization is a requirement for urban construction and traffic information development. Urban highway networking and even the whole country must be integrated into the network, which requires traffic LED display signs to be more intelligent. Intelligent Trans-portation System (ITS) refers to an intelligent information system that provides integrated traffic information services to the public or special audiences. As an important display carrier and window for intelligent transportation, LED display is bound to be more humanized and convenient in terms of intelligent control.
Standardization mainly refers to the LED traffic display has a more advanced standard in product and system testing and evaluation. At present, the reference standards for LED traffic displays mainly include the “Guidelines for Passenger-Guided LED Information Display†of the Ministry of Railways, the “Variable Information Board Standards for Expressways†and the “Variable Speed ​​Limit Signs for Expressways†of the Ministry of Public Security. "City Traffic Guidance Information Board Standard" and so on. The release and implementation of these standards constitute the basic framework of the standardization system for LED displays in China, and play a major role in regulating market development and promoting industrial upgrading.
