NB-IoT: The Best Open Off-Street Smart Parking Solution

As the economy continues to grow and people's living standards continue to improve, the number of cars owned by the city has risen sharply, and the management of open street parking in the city has become increasingly difficult. If the efficient and reasonable management of on-street parking, it can effectively alleviate the problem of parking difficulties. At present, there are several types of on-street parking management as follows:

First Generation Manual Management

Completely rely on people to do open street parking management. Faced with the following problems:

1, charge management chaos: indiscriminate charging, inaccurate billing, charging disputes, fraudulent operation of the collector, fake collectors charging indiscriminately;

2, low efficiency of operation and management: limited management area of the toll collector, difficult to supervise the charges, and unable to recover the outstanding fees;

3、High operation and management manpower cost;

4. Long working hours and low wages for toll collectors, which are not attractive enough and make staff turnover fast.

Second Generation Metered Parking Management

 Adopt the "meter" timing card charging method, relying on the car owner to finish timing and payment on the meter. Compared with the first generation of manual management, this reduces the problem of confusion in charge management and lowers labor costs, but because it relies entirely on the autonomy of car owners, it faces problems such as car owners' evasion of fees, which is difficult to supervise, high maintenance and operation costs of equipment, and finding vacant street parking spaces.

The third generation of traditional wireless intelligent parking management

The vehicle detector is installed on the ground of the parking space, and the vehicle occupancy information is reported to the operator's wireless network using two-hop technology (the vehicle detector reports the information to the convergence gateway through short-range propagation technology such as Zigbee, and then the convergence gateway reports it through 2G/3G network), and then the parking management platform is used for intelligent management. Owners can easily check the surrounding roadside free parking spaces through the cell phone APP, and finish the inquiry and payment by themselves; owners can manage the parking system in real time through the parking management platform, and if needed, it can also be docked to the government traffic management to facilitate the management of urban parking violations.

Compared with the previous second generation, the degree of intelligence is greatly enhanced. But the disadvantage is that wireless communication using non-authorized frequency band, private wireless LAN, there are signal interference problems, network stability security is poor, may lead to inaccurate charging information; convergence gateway coverage is limited, usually a convergence gateway can only manage 10 ~ 15 parking spaces, inefficient, equipment costs and deployment costs are high; different intelligent parking equipment manufacturers use private wireless short-range propagation technology, can not be compatible. cannot be compatible.

Fourth generation NB-IoT intelligent parking management

NB-IoT (Narrowband IoT) technology is a revolutionary narrowband IoT technology based on cellular network, focusing on the low-power wide coverage (LPWA) Internet of Things (IoT) market, which can be widely used in 3GPP communication standard technology worldwide and is one of the key technologies of 4.5 G is one of the key technologies. Compared with the current widely commercialized 2G/3G/4G and other wireless technologies, it features wide coverage (20db gain), many connections (100,000 links), low cost (less than $5 for modules), and low power consumption (10 years for batteries). These advantages make it very suitable for smart parking, smart meter reading, smart monitoring, logistics tracking, smart agriculture and other IoT applications.

Compared with the third generation of on-street parking management, NB-IoT provides carrier-level network guarantee and greatly improves reliability and security; reduces the convergence gateway deployment, and the overall cost (equipment cost, deployment cost, maintenance cost) drops by about 30%; the vehicle detector is plug-and-play, simple installation and construction, no need for network technician support, and the subsequent smart parking expansion is simple, without considering network compatibility issues. Then through the unified cell phone APP and parking management data platform, it can provide unified intelligent parking services for city residents.

Take 20,000 on-street parking spaces in the city as an example, the whole city adopts NB-IoT smart parking management, and the NB-IoT smart parking management system can reduce 660 convergence gateways compared with the third generation of on-street parking management, saving convergence gateway equipment and deployment cost about 5 million, and saving 500,000 maintenance cost per year.

The cell phone APP can provide car owners with on-street parking space inquiry and parking space navigation, which can effectively help car owners find vacant parking spaces quickly, saving their time and invalid fuel consumption, and improving the turnover rate of on-street parking spaces, relieving road congestion and reducing exhaust emissions, with both economic and social value.

In addition, the cell phone APP also provides roadside parking space booking function, through the appropriate booking fee, can increase the road car parking space owners side income, to 1 parking space daily income of 10 yuan booking fee, for example, 20,000 parking spaces a year can be more income of 73 million yuan. Owners can also complete the parking fee payment and inquiry through the cell phone APP, which is convenient and fast and reduces the fee dispute.

At the same time to provide the owner side through the parking management system and the owner management APP, parking space administrator can real-time query parking space and payment, effectively expanding the management scope of the parking administrator, thus saving personnel manpower costs, 20,000 parking spaces originally required 400 parking fee collectors, is expected to reduce the roadside parking space management manpower can be 80%, can save 9.6 million a year manpower costs; at the same time also It can also solve the problems of inaccurate billing, indiscriminate charging, difficult to supervise charging and charging chaos such as counterfeit charges, which is expected to recover the original lost revenue of 73 million yuan (1 parking space lost 10 yuan per day).

At the same time, through the parking management system, the management owner can analyze the charging and occupancy of parking spaces, providing data support for scientific management monitoring and time-of-day charging. In addition, docking the NB-IoT open roadside parking management system with the government's traffic management system can set up parking space guidance display on the road to effectively alleviate traffic congestion; for the situation of unpaid parking spaces timely notify the traffic police for violation processing, effectively solving the phenomenon of indiscriminate parking and fee evasion.

 Therefore, NB-IoT intelligent parking management is the best open roadside intelligent parking solution, which can scientifically and efficiently solve the problem of urban roadside parking management. These advantages of NB-IoT technology will greatly promote the intelligent process of open roadside parking. It can be foreseen that as China's urban road parking management becomes more and more difficult and the requirements for efficiency and intelligence become higher and higher, NB-IoT intelligent parking management system will be the best choice for open roadside intelligent parking solutions.
