NB IOT Will Be the Best Open Roadside Intelligent Parking Solution

First generation manual management

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

1. Confusion in charge management: arbitrary charges, inaccurate charges, many charge disputes, many fraudulent operations by toll collectors, and arbitrary charges by fake toll collectors;

2. Low efficiency of operation and management: the management area of toll collectors is limited, the collection is difficult to supervise, and the arrears can not be recovered;

3. High labor cost of operation management;

4. Toll collectors have long working hours, low salary, insufficient attraction and fast personnel flow.

Second generation meter parking management

Adopt the method of "meter" timing and card charging, and rely on the car owner to complete the timing and payment on the meter. Compared with the first generation of manual management, it reduces the problem of chaotic charge management and reduces the labor cost. However, due to the complete dependence on the autonomy of car owners, car owners are faced with fee evasion and it is difficult to supervise the charge; The later maintenance and operation costs of the equipment are high, as well as the search for idle roadside 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 two hop technology is used to report the vehicle occupation information to the wireless network of the operator (the vehicle detector reports the information to the convergence gateway through ZigBee and other short-range communication technologies, and then the convergence gateway reports through 2G / 3G network), and then carries out intelligent management through the parking management platform. Car owners can easily query the surrounding roadside free parking spaces through mobile app, and complete the query and payment by themselves; The owner can manage the parking space system in real time through the parking management platform. If necessary, it can also connect with the government traffic management to facilitate the management of urban parking violations.

Compared with the previous two generations, the degree of intelligence is greatly improved. However, the disadvantage is that the wireless communication adopts unauthorized frequency band, and the private wireless LAN has the problem of signal interference, poor network stability and security, which may lead to inaccurate charging information; The coverage of convergence gateway is limited. Generally, one convergence gateway can only manage 10 15 parking spaces, which is inefficient and has high equipment cost and deployment cost; Different intelligent parking equipment manufacturers adopt private wireless short-range communication technology, which is incompatible.

The vehicle detector using NB IOT (narrowband Internet of things) technology directly reports the information to the operator's wireless network, and there is no need for convergence gateway. NB IOT is an innovative narrowband Internet of things technology based on cellular network. It focuses on the low-power wide coverage (lpwa) Internet of things (IOT) market. It is a 3GPP communication standard technology that can be widely used all over the world. It is also one of the key technologies of 4.5g. Compared with the widely commercial 2G / 3G / 4G and other wireless technologies, it has the characteristics of wide coverage (20dB gain), more connections (100000 links), low cost (less than $5 for modules), low power consumption (10 years of battery), etc. These advantages make it very suitable for intelligent parking, intelligent meter reading, intelligent monitoring, logistics tracking, intelligent agriculture and other Internet of things applications.

Compared with the third generation roadside parking management, Nb IOT provides operator level network guarantee, which greatly improves the reliability and security; The deployment of convergence gateway is reduced, and the overall cost (equipment cost, deployment cost and maintenance cost) is reduced by about 30%; The vehicle detector is plug and play, easy to install and construct without the support of network technicians. The subsequent expansion of intelligent parking space is simple without considering the problem of network compatibility. Through the unified mobile app and parking management data platform, it can provide unified intelligent parking services for urban residents.

Taking 20000 roadside parking spaces in the city as an example, the whole city adopts NB IOT intelligent parking management. Compared with the third generation roadside parking management, Nb IOT intelligent parking management system can reduce 660 convergence gateways, save about 5 million convergence gateway equipment and deployment costs, and save 500000 maintenance costs every year.

The mobile app can provide roadside parking space query and parking space navigation for car owners, effectively help car owners quickly find free parking spaces, save car owners' time and invalid fuel consumption, improve the turnover rate of roadside parking spaces, alleviate road congestion and reduce exhaust emissions, which has both economic and social value. In addition, the mobile app also provides the roadside parking space reservation function. Through the appropriate reservation fee, the income of the owner of the road parking space can be increased. Taking the reservation fee of 10 yuan per day for one parking space as an example, 20000 parking spaces can earn 73 million yuan more a year.

Car owners can also pay and query parking fees through mobile app, which is convenient and rapid to reduce charging disputes. At the same time, it provides the owner with the parking management system and the owner management app. The parking space administrator can query the parking space and payment in real time, effectively expanding the management scope of the parking administrator, so as to save personnel and labor costs. 20000 parking spaces originally required 400 parking toll collectors, and it is expected that the roadside parking space management manpower can be reduced by 80%, It can save 9.6 million labor costs every year; At the same time, it can also solve the problems of inaccurate charging, arbitrary charging, difficult supervision of charging and charging by fake toll collectors. It is expected to recover the original lost income of 73 million yuan (10 yuan per day for one parking space).

At the same time, through the parking management system, the management owner can analyze the charging and occupation of parking spaces, so as to provide data support for scientific management, monitoring and time-division charging. In addition, by connecting the Nb IOT open roadside parking management system with the government's traffic management system, parking space guidance display can be set on the road to effectively alleviate traffic congestion; For unpaid parking spaces, timely notify the traffic police to deal with violations, so as to effectively solve the phenomenon of disorderly 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. NB IOT technology provides operator based network, which greatly improves reliability and security; Provide ubiquitous coverage. Vehicle detectors can be installed in places with good mobile phone signals and in places with poor mobile phone signals; The vehicle detector is plug and play, and the subsequent expansion of intelligent parking space is simple and convenient; Compared with the existing 2 / 3 / 4G and other wireless technologies, the power consumption is small and the chip cost is low. These advantages of Nb IOT technology will greatly promote the intelligent process of open roadside parking. It can be predicted that with the increasing difficulty of urban road parking management and the higher requirements for efficiency and intelligence, Nb IOT intelligent parking management system will be the best choice for open roadside intelligent parking solutions.
