Bluetooth channel spikes and bicycle smart locks generate signal interaction, automatically identify whether the vehicle is reasonably parked in the designated area, until the user parks the bicycle to the specified area. This intelligent "fixed-point car replacement" model not only solves the problem of disorderly management of shared bicycles, but also meets the needs of enterprise development, but also makes urban management more refined and intelligent.
Since the birth of shared bicycles, it has always shouldered the mission of solving the "last kilometer of travel" and continuously promoted green travel and convenient travel for residents. However, the disorderly development of the early stage of the market has led to many unexpected problems, such as the negative impact of vehicles parked randomly, crowding blind lanes and other negative impacts that damage the urban environment and public safety.
The original "last kilometer of green travel" has unconsciously undergone a qualitative change, becoming "the most disturbing kilometer in the city".
In the face of these problems, whether it is a shared bicycle operator or a local government authority, it is necessary to face great pressure. But in fact, the application of Internet of Things technology to the shared bicycle industry has long been "familiar", and it is not difficult to use technical means to make up for the loopholes in shared bicycle operations.
A striking "box"
This morning, many media "invariably" reported such a news:
Recently, the shared bicycle parking spots on the streets of Shanghai have installed a striking blue circular equipment on the ground, which is clearly marked with the prompt of "safe travel, standardized parking", which is the "Bluetooth road nail" piloted by the staff to control the chaos of shared bicycle parking in the jurisdiction, which can send a signal to each shared bicycle, that is, when the bicycle receives the no-stop signal, its car lock cannot be locked, and when the vehicle receives the parkable signal, it can successfully unlock.
A small solution, but to solve the problem of both shared bicycle operators and government regulators, creating great value.
As a major area that cannot be ignored in the future urban transportation, shared bicycles have always attracted the attention of the Internet of Things industry. According to the white paper "Application, Evolution and Ecological Value of Shared Bicycle Internet of Things Technology" jointly released by Shanghai Unicom Internet of Things Research Institute and Hello Travel, the current social ownership of bicycles in China has reached nearly 400 million and electric bicycles are nearly 300 million. According to the current development rate of the shared two-wheeler industry and the assessment of China's total population needs, the total number of shared bicycles is expected to reach 30 million in the future.
In the face of such a huge number of "national travel tools", how to carry out refined management has become a common problem for shared bicycle operators and relevant government departments. Specific to the problem of random placement of bicycles, disorderly placement is very common, especially in peak periods, whether it is because of personal quality or other reasons, it seems to be an "impossible" task to place bicycles neatly in the parking area.
For a long time, the user's attitude towards shared bicycle operators is that "they are just commercial traders who pursue profits and do nothing"; and the relevant government departments have "encroached" on shared bicycles and other issues, and the first thing to be held accountable is also shared bicycle operators, which will lead to the relevant departments having to limit the number and scope of operators' bicycle operations.
For shared bicycle operators, as providers of commercial services, the biggest difficulty is not these, but in every time the user finds a car, it is difficult to use the car, so that the user loses confidence in the brand, resulting in the loss of users, so that the cycle causes the profit damage in the operation of the shared bicycle, and finally can not complete the closed loop on the business model.
In the above news, when the shared bicycle user parks the bicycle, the Bluetooth road spike will interact with the bicycle smart lock to automatically identify whether the vehicle is reasonably parked in the designated area until the user parks the bicycle to the specified area. This intelligent "fixed-point car replacement" model not only solves the problem of disorderly management of shared bicycles, but also meets the needs of enterprise development, but also makes urban management more refined and intelligent.
How to solve the "last mile" congestion of "Bluetooth road spikes"
In fact, the application of "Bluetooth road spikes" to shared bicycles is not a new attempt. Bluetooth road spike is a precise positioning of the column judgment technology, this device can transmit signals, and beidou satellite installed on the shared bicycle high-precision split lock communication, to achieve bicycle pileless fixed-point parking.
Bluetooth road spike is equipped with Bluetooth sensor device inside, which can match the Bluetooth on the lock of the shared bicycle, and by installing the device in the parking area, using Bluetooth high-precision identification and prompting, a virtual Bluetooth electronic fence is formed. When the shared bicycle enters the range covered by the electronic fence signal, the built-in Bluetooth chip of the bicycle smart lock can determine the relative position of the vehicle according to the size of the Bluetooth electronic fence signal strength and the corresponding number of Bluetooth road spikes.
The sensing distance of each Bluetooth road spike is generally 75-100cm, after equipment debugging, the shared bicycle can only be locked in the designated area to complete the lock operation, if it is not parked in the parking wire frame of the road spike induction, it may not be possible to lock the bicycle, so it is impossible to finally complete the car rental billing.
As early as January 2020, the central area of financial street in Beijing's Xicheng District adopted the technology of entering the fence based on Bluetooth road spikes, and cooperated with the Bluetooth sniffing electronic fence to build and open the "entry settlement" system model. The Bluetooth sniffing system can detect the unique code of shared bicycles within a radius of about 50 meters, and count the number of bicycles of each brand, parking time and other information through edge calculation.
In January last year, Bluetooth Daodeng was "online" in Chengdu, and the three major shared bicycle giants of Hello Travel, Green Orange Bicycle and Meituan Bicycle all made relevant deployments. Hello Travel uses the multiple precision positioning of Bluetooth road spike "GPS + Beidou Navigation + WiFi", which can make the vehicle identification range reach 1 meter. If the vehicle does not park in the designated area, the user will be deducted the riding license points, and will not be able to continue to use hello bikes after deduction.
Nowadays, "Bluetooth Road Spike" has blossomed all over the country. Of course, this is also directly related to the value it produces. According to a set of data statistics after the use of "Bluetooth road nails" in Fengpu Street, Fengxian District, Shanghai, after realizing the fixed-point car change, the Fengpu Street jurisdiction has gone from parking more than 400 bicycles in an orderly manner every day to 98% of the standardized return rate, basically realizing standardized parking. In the two pilot areas, the operation and maintenance personnel have also been reduced from the original 5 people per day to 2 people, and the cost of bicycle management operation and maintenance has been reduced in a straight line.
Other options for precise parking
Of course, in addition to Bluetooth road spikes, there are other means for accurate parking, such as September 30, 2021, In Mile City, under the jurisdiction of Honghe Hani and Yi Autonomous Prefecture in Yunnan Province, an electromagnetic induction return settlement system based on NFC technology was introduced.
Specifically, the NFC tag is implanted in the designated parking area on the ground, which can be directly used to water the ordinary asphalt paint with a temperature close to 200 degrees, and through the NFC reader at the bottom of the shared electric bicycle, when the vehicle reaches the parking position, it can complete accurate positioning identification, thereby guiding the user to park the vehicle correctly and orderly.
The advantages of precision parking solutions using NFC technology are low construction and maintenance costs, as well as outstanding advantages in terms of performance and safety.
However, the shortcomings of NFC technology are also very obvious, and it is necessary to overcome the problem that the recognition range of ground tags is small, so that users can have a high degree of accurate recognition rate at will, which in the real environment, the card reading distance requirements need to be greater than 25 cm. In addition, the ground NFC tag also needs to resist pressure and high temperature on chips and materials, breaking the restrictions of the harsh use environment.
In addition to NFC technology, GPS solutions, UHF 900MHz positioning is also often used in accurate parking positioning, of course, these positioning technologies for sharing bicycles also have their own advantages and disadvantages.
For example, the GPS solution positioning accuracy is 2-3 meters, but the shade or building will block the signal, resulting in poor user experience; UHF 900MHz positioning accuracy is about 0.5 meters, but the cost of the card reader is higher.
All in all, sharing bicycles, as a major area that cannot be ignored in the modern intelligent transportation system, is also driving the continuous development of domestic Internet of Things technology applications, and at the same time, Internet of Things sensors, positioning technology, connection technology and related cloud technologies can feed back the benign development of the shared bicycle industry. Whether from the perspective of economic and social benefits, it is of great benefit.
