With the development of cities, people’s living standards are gradually improving, and most families are equipped with cars. But when it comes to parking, especially in big cities, we have to talk about the difficulty of parking. Because of the gradual fermentation of the parking problem, smart parking was born out of luck.
The development potential of smart parking is huge
The deployment rate of intelligent equipment in parking lots in my country is generally at a low level, and there is still huge room for improvement in the future. It is estimated that by 2020, the market size of the smart parking industry will reach 15.4 billion yuan; in 2010, the market size was less than 1.5 billion yuan.
In July 2019, the Ministry of Public Security and the Ministry of Housing and Construction issued the “Guiding Opinions on Strengthening and Improving Urban Parking Management Work” to accelerate the construction of parking and charging infrastructure, revitalize existing berth resources, innovate parking information applications, and strengthen key areas Berth management, give full play to the role of urban communities, and create a management work pattern of joint construction, joint governance and sharing.
Smart parking has a broad market prospect and the support of favorable government policies, making smart parking a natural “outlet” at the moment, which also depends on the rapid development of the Internet of Things technology behind it.
Under the “outlet” of smart parking, the Internet of Things technology is the core
Smart parking is based on parking spaces as a resource, and comprehensively utilizes cloud computing, Internet of Things, serial rs232 to wifi converter artificial intelligence, mobile Internet and other technologies to meet the parking methods of both the parking space provider and the demand side.
To put it simply, smart parking refers to intelligent and informatized parking. It mainly helps car owners realize daily services such as parking space guidance and parking payment, and helps administrators realize intelligent parking and efficient operation.
In urban smart parking management, IoT communication technology is the key.
Especially in areas such as underground garages, traditional networks have the problems of deep network coverage and high power consumption of terminals. In recent years, LPWAN has appeared in the public eye with its advantages of “high coverage and low power consumption”. Among the many LPWAN technologies, the domestic parking industry pays the most attention to LoRa and NB-IoT technologies, which bring new technologies to smart parking. technical experience.
Who will win between NB-IoT wireless technology and LoRa wireless technology
As the most promising low-power wide-area network communication technology in China, NB-IoT technology and LoRa technology have been bundled and compared. Is it fighting in the same room or peaceful coexistence?
NB-IoT technology
NB-IoT (Narrow Band Internet of Things, narrowband Internet of Things), which belongs to the narrowband part of 5G technology, is based on cellular network construction and consumes about 180KHz of bandwidth. Power consumption, stable connection, low cost, and excellent architecture optimization have attracted much attention.
As long as the vehicle is parked in the parking space, the wireless vehicle detector will automatically collect and broadcast the vehicle’s position, status and other signals, and realize the real-time upload of the parking space data through the NB-IoT network, and communicate with the parking guidance screen, the background management system of the parking lot, and the traffic control department. Realize information interaction between the parking lot, etc., and finally realize the efficient scheduling and supervision of the parking lot.
LoRa Technology
The use of NB-IoT technology mainly depends on the operator’s infrastructure. In many places with harsh conditions, the operator’s infrastructure does not fully cover. LoRa technology is a more convert ethernet to wifi flexible autonomous network, which can be deployed wherever it is needed. Individuals can become “operators” only by deploying LoRa gateways.
Another point is security. NB-IoT is an operator network, so the data is transmitted to the operator first. Many enterprises are unwilling to give their data to others, so these enterprises will choose to install their own gateways and deploy LoRa networks flexibly.
The LoRa module works in the unlicensed frequency band below 1GHz, so there is no need to pay additional communication fees during application, which can reduce the operating cost of the parking lot to a greater extent.
Complementary advantages of hybrid networking
From a technical point of view, there is actually not much difference between LoRa and NB-IoT; from the point of view of application scope, the two are actually the same in many ways, and the main solutions are low power consumption and large connection. , wide coverage, and large capacity; the main difference is that NB-IOT uses an operator network, while LoRa is a self-built network.
In fact, there is a complementary relationship between NB-IoT and LoRa wireless technology.
In complex situations, whether it is NB geomagnetic + operator + parking platform, or LoRa geomagnetic + gateway + parking platform, it is difficult for a single networking solution to achieve excellent network and cost, and it may be difficult to fully cover the project area or the cost is high.
If you want to achieve the optimal network and cost, you can use the LoRa gateway and TurCloud™ IoT platform independently developed by Tuobao Technology to connect LoRa and NB-IoT geomagnetism at the same time, realize hybrid networking, and flexibly fill blind spots to meet the needs of on-street and off-street parking areas Application scenarios such as underground garages and underground garages that have high requirements for network depth and breadth coverage, while achieving the lowest construction and construction costs.
Smart parking connects scattered parking lots through the wireless communication technology of the Internet of Things, breaks the island of information, realizes the optimal allocation of limited parking resources, solves urban parking problems, and helps smart transportation and smart city upgrades. It has broad development prospects and market space. It has become a vertical field that cannot be ignored in the Internet of Things.
