Who Will Take the Lead in the Debate on Road Parking Detection Technology of Geomagnetic Vs Video -

Roadside parking can be seen everywhere now. Although it can be seen at a glance in the open air, it is difficult to understand it in real time with manpower. Many roadside parking systems only show that there are vacant parking spaces around, but the specific situation of vacant parking spaces is unknown. There is a lack of dynamic push of specific empty parking space information. The emergence of road parking detection technology has well solved this problem and made parking spaces play their greatest role.

Road parking detection technology mainly includes: meter, POS machine, geomagnetic technology and video technology. Putting aside the traditional meters and POS machines, the dispute over road parking detection technology in 2018 will be manifested in the dichotomy of geomagnetic and video technology. Geomagnetic technology and video technology have obvious advantages and disadvantages: geomagnetic Technology: cheap price, convenient installation and easier project implementation. The disadvantage is that it still needs to be manned; Video technology: with capture function, image evidence can be retained, and capture for fee evasion can provide a complete evidence chain. The disadvantages are high cost, difficult installation, no obstacles, and more government departments should be coordinated in the implementation of the project.

How do they connect all parking spaces into a network? Geomagnetic technology equipment adopts Internet of things technology. If a sensor is installed on the parking space, the data information of whether the parking space has stopped can be transmitted to the background computer through this transponder, and the computer will feed back these information to the terminal, such as mobile phone. Video technology uses the digital HD camera installed at the entrance and exit of the road or parking lot for information collection and automatic analysis, so as to obtain the roadside parking space information, which can realize the capture, identification and comparison of license plates, detection of some traffic events and capture of violations. At the same time, it provides various information to the central platform for decision-making and real-time push of the idle state of the parking space. In the early years, video piles have been used, but they have not been widely popularized due to technical obstacles.

Due to the technical difficulty and complex application scenarios, the cost of high-level video is relatively high. In addition, in the actual scene, the hard injury of the video scheme is that if it is blocked by trees, it is necessary to trim branches and even cut trees. This undoubtedly increases the difficulty of project implementation, in which there are many relevant departments that need to be coordinated and the procedures are very complex. Industry insiders said that a project often needs to coordinate various departments such as CCCC, municipal, garden, urban management and electric power. According to the comprehensive consideration of all aspects, geomagnetic technology has the advantages of low cost, relatively convenient construction and no power connection, which is also part of the reason why geomagnetic technology was preferentially selected as the parking space acquisition scheme in the early stage of the construction of urban parking management platform.

Geomagnetic detection rate, video capture rate and recognition rate are the focus of contention. Each family claims that its products can reach 98-99%, but in actual road operation, external environmental interference will significantly reduce this index. Is such a high detection rate required in the actual project? Insiders said that the current parking projects are inseparable from labor. If it can reach 98%, there will not be so many operators to intervene in the parking space. After reading several bidding documents, it is found that the owner has high requirements for this technical parameter, generally not less than 95%, and even 98%. Of course, no matter what kind of technology, it is good technology that can alleviate the problem of parking and bring convenience to people's life.
