The value-added but existing standards and management issues in the Internet of Things traffic field

All things in the world, from buildings to small keys, can be made smart by embedding a miniature sensor chip. This is the Internet of Things. In this city, the most important thing that should be armed with the Internet of Things is traffic, because without intelligent traffic has given us enough headaches.

The transportation plan was blossomed at the 2011 China International Internet of Things Expo. There were more than 70 solutions related to the Internet of Things in the transportation industry exhibited and introduced. Specific induction can be summarized in the following three aspects:

First, e-government. For example, road transport administration, traffic enforcement, etc. Take a look at the typical application of IoT in road management. A door, the sensor will feel the alcohol level of the owner, through the chip installed in the car to the traffic police department, the traffic police department will immediately send a text message to the owner, to remind the owner should no longer drive, if the owners ignore, traffic police It can be judged whether the vehicle's driving speed is zero, and the police should be handled immediately.

Second, intelligent transportation. In traffic management, the Internet of Things can improve the efficiency of road use, facilitate the management and control of vehicles, and can use RFID to quickly locate statistical data on transportation tools. The main applications are non-stop charging, automatic vehicle identification, transportation management, and parking lot access control and management. There are also transport tickets that allow automatic ticketing and automatic billing. ZTE has had many years of research in this area. ZTE believes that the inability of RFID to connect to the Internet has always been an important reason for restricting its development. From A to B, there are always multiple roads that can be reached, but these roads may be divided into different provinces and cities or owners. It is difficult to cut the tolls. The usual way is to set up toll stations for each road. Through data collection, RFID can easily record the route of the car and provide a basis for fee collection among owners. According to Du Jiang, chief engineer of ZTE Tianjin Zhongxing Software Co., Ltd., “The core of the Internet of Things in the transportation industry is not to identify information, but to process information.” ZTE's Ambiguous Path Identification solution can solve multiple owners' environment. , The issue of free parking fees on the highway. “At the same time, ZTE is also discussing with various localities to solve the problem of road congestion in urban core areas through RFID. When vehicles enter the core areas of the city and how long they can enter, they can record via RFID. This method has been applied in London.”

Third, for logistics and supply chain management. It can use RFID tags on different logistics units such as containers, pallets, and crates. It can automatically identify and track logistic units. It is mainly used for warehouse management, logistics distribution and other services. In the 2011 China International Internet of Things Expo, a number of planners exhibited their solutions for containers. First of all, RFID tags can replace the role of seals to ensure that containers are not opened during transportation, which can greatly improve the speed of logistics clearance. At the same time, when transporting some dangerous goods, RFID tags can also monitor the temperature, humidity, and even vibration amplitude of the box. Yao Chen, senior sales manager of the Neusoft Group's Transportation Division, believes that due to cost and flow speed considerations, it is not suitable to equip each item with an RFID tag, but the use of RFID tags in each container and every container has become The industry's popular practice.

The Internet of Things under the Internet of Things can not only be on the road, but also can go to the sea. At present, China's ports are divided into four levels: First, large coastal ports, such as seaports, Shenzhen ports, and Qingdao ports, the degree of informatization of such ports has reached a relatively high level; second, coastal medium-sized ports and large inland ports, such as Yingkou Port, Yantai Port, Rizhao Port, and Nanjing Port; Third, coastal small ports; Fourth, inland small and medium-sized ports.

It is based on the unbalanced nature of the development of the port that Ni Peng, the Institute of Water Transportation Science and Technology, Ministry of Transport, proposed the idea of ​​building smart shipping using the Internet of Things.

Ni Peng divided the smart shipping system into four phases: the first is the early information and shipping phase. At this stage, it mainly uses information technology to transform and reorganize the water transport production process. The second is the digital shipping phase, through which the water transport region Digitalization realizes dynamic real-time monitoring and management of water transportation business processes and changes in various types of passenger and cargo information. This is the stage that most of our ports are going through. The third is the smart shipping phase. Through the effective integration of advanced communication technologies, electronic sensing technologies, and control technologies, a large-scale and comprehensive water transportation management system has been established. The fourth stage is to provide services for acquiring, delivering, storing, recognizing, deciding and using information at any time, any place, any service network and any object in the field of water transport, and provide real smart shipping services. Technical support and support.

At this stage, Ni Peng puts forward the following suggestions to the planners concerned with water transport: First, it can focus on the sensor technology-based inland navigation infrastructure and navigation environment awareness technologies. Such as the navigation hub, the associated environment of the waterway, and the state of the ship's navigable environment. At the same time, we can pay attention to the networking technology based on the ship network, the basic network of shipping information services based on wide-area water coverage, the collection and aggregation of shipping data resources, the integration and integration of shipping and ship information, the dynamic update of electronic navigation charts, and three-dimensional virtual navigation channels. Intelligent shipborne, shore-based intelligent equipment.

Hidden Concerns behind the Prosperity Although there are already nearly 70 solutions for the Internet of Things in the internal transportation sector, the following two issues have become more prominent: First, the point cannot be met. Although the Internet of Things solution has applications in the transportation field, it is also distributed in dots, that is to say, in some cities, it has realized the opportunity of the Internet of Things intelligent traffic management system, and once the automobile out of the city, the information can not be connected , Or at a certain stage of logistics through RFID management, but in the entire logistics cycle, there are still many blank spots. Second, the application lacks standards. The same industry adopts different application standards, and it will be difficult to implement the "small network into a large network" in the future. In this regard, Wang Xiaojing, chief engineer of the Highway Research Institute of the Ministry of Transport, believes that the RFID standard includes the standard system, application interfaces, and operating protocols. “We cannot copy foreign standards systems because foreign standards do not form a system. In the transportation industry, we must have our own standards. Our country is concerned with the application of standards and concerns the ease of use and safety of standards. The country will be more In the application of 433MHz, 860-960MHz and 2.45GHz frequency bands, 5.8GHz applications have been relatively mature."

At the same time, Wang Xiaojing criticized the practices of certain manufacturers: “Some manufacturers have the problem of falsifying RFID tag parameter indicators. Doing so in a short period of time does not affect the use of applications. It will affect interconnection and interoperability in the short term and cannot form the industry-wide IoT.”
