What is smart metro?
No customer service? yes!
Passenger distribution perception? sure!
Automatic optimization of station environment? no problem!
Waiting guidance? well!
No feeling to buy tickets? Accept!
Insensible security? Make it happen!
Smart subway, which can satisfy people’s imagination of smart travel, is coming.
On September 9, Guangzhou smart Metro demonstration station was officially launched in Guangzhou Metro Line 3 and Guangzhou tower station of APM line.
Zhou Jing, vice president of Guangzhou Pingao Software Co., Ltd. (hereinafter referred to as “Pingao software”) and director of Guangzhou Qingyun Computer Technology Co., Ltd. (hereinafter referred to as “Qingyun technology”), together with leaders and guests from various urban rail transit companies in China, visited and experienced the Guangzhou tower demonstration station, witnessing the new achievements of smart metro construction.
In the smart Metro demonstration station, passengers can experience a series of Metro intelligent functions such as senseless traffic, intelligent security inspection and so on.Among them, the face recognition data Lake constructed and supported by Qingyun technology has promoted the security system of Guangzhou Metro to a new height.
Big event! Revolutionary upgrade of safety of Guangzhou Metro
Face recognition is not a new topic. butThe Guangzhou Metro face recognition system provides more secure and intelligent security capabilities through intelligent data Lake technology.Face data is safely managed in the data lake and shared to various application systems for quick use. It hasAccess to public security Internet plus trusted identity authentication platformThrough fast and real-time comparison of passenger identity, strengthen supervision, protect the legitimate rights and interests of passengers and personal safety, and provide guarantee for the safe travel of passengers.
Behind the senseless security check,
The public security level intelligent data Lake quietly lurks under the water,
Safeguard the safety of passengers at all times.
Compared with the traditional face recognition database, pinko intelligent data Lake embodies five characteristics of “larger, more complete, wider, more accurate and more intelligent”.
1. More faces
Pinko intelligent data lake has supported more thanOver 80 million faces。 At present, the permanent population of Guangzhou is14 million 904 thousand and 400According to the daily average passenger flow of Guangzhou Metro9 millionIn terms of person time calculation, pinko intelligent data lake is fully equipped with the background support capability of face data for passenger travel.
2. More storage capacity
Pinko intelligent data lake has been owned by customers in a single environmentPb gradeThe practical experience of data storage is closely related to the background support of pinnacle cloud. At present, the support demand of Guangzhou Metro’s ten million level face database is only inTB level。
1. More complete passenger information
Through the data acquisition mode of “cloud + terminal”, the iterative system of data updating is formed, and the relationship information and track information of passengers are gatheredHolographic archives of passengers。
2. More secure passenger privacy data
Compared with the traditional face database, pinko intelligent data lake has a more powerful security mechanism for passenger privacy. First, the pinko intelligent data lake can protect the privacy data security of passengers through a series of control measures, such as data classification, data desensitization and declassification, image watermarking, data authentication, etc. The second is to combine the service ability of Pingao cloud to make the data lake have“No data out of the lake, no cloud computing”Support capacity of. It realizes that the data of background analysts of each intelligent application manufacturer is available and visible, the application data of front-end site is available and invisible, and the data of other information systems is not available and invisible.It not only ensures data security, but also promotes the development of intelligence and intelligence。
3. Safer passenger identity
The track information of passengers is linked with the police’s brain. As soon as the criminals enter the subway, they will be in the sight of the public security brain, so that the criminals have no place to hide.
1. Support more intelligent manufacturers
In the actual customer production environment, pinko intelligent data lake has the support experience of supporting 38 units, more than 10 different human face algorithm manufacturers access, and more than 60 big data algorithm manufacturers’ analysis. At present, pinko intelligent data Lake in Guangzhou Metro has supported the application of radio and television express, Yushi technology, Tongfang Weishi, Jiadu, Tencent and other manufacturers in the intelligent scene.
2. Support wider recognition patterns
In addition to the pure face authentication mode currently adopted by Guangzhou Metro, pinko intelligent data lake also supports higher verification accuracy and larger storage capacity1 + n identity verificationFor example, it can support the passenger’s identity verification using the passenger’s boarding code and face.
3. Support more computing methods
Besides supporting the traditionalCentral computing modelCan supportEdge computing model。 The edge computing node only needs to synchronize the incremental eigenvalue data calculated by the center to complete the application of face recognition in the edge site.
1. More accurate passenger identity information
Through the Internet plus trusted identity authentication platform, the real and real identity of passengers is verified. Let the passengersThe basic identity information is more accurate, the source is more authoritative and the information is more reliable。
2. More accurate passenger image information
Through the establishment of “cloud + end” data error correction mechanism, and combined with the cloud intelligent analysis model. formationImage optimization mechanism of interaction between cloud and terminal。
Through the data gathered with the acquisition end, the face trajectory database is built, and the self-learning mechanism is established. And through the quality control system intelligent update data Lake data. Form aSelf renewal iteration, self-learning intelligent data Lake。
300ms, the ultimate experience of face brushing is better than card swiping
Based on the support of pinnacle intelligent data lake, passengers’ face brushing is better than card swiping experience.
Passengers pass the gate at normal walking speed without any stagnation. The original peak even need to queue up for 7, 8 minutes of security, gate operation can now be completed in a few seconds.
The traditional gate can identify the passenger ticket card in 300 milliseconds, but it takes a little time for people to pass. At present, face recognition based on pinko intelligent data lake has reached the recognition speed of 500 ms, and identity recognition and ticket checking are completed in one go.
With the follow-up collaborative optimization of face recognition system, the “super high speed” potential of intelligent data lake will be further developed, and the recognition speed of 300 ms will be achieved, which will truly give passengers “flying average” passing speed.
The more attention, the safer
Compared with other modes of transportation, the subway is almost one of the safest options.
At present, with the advent of the era of smart metro, the travel safety of passengers will be further improved.Especially when smart data lake is connected to the public security Internet plus trusted identity authentication platform, the subway will become a forbidden place for Jacky Cheung’s concert.
However, not all “wisdom” is necessarily associated with “security”.
Only by putting security at a high priority and paying special attention can we truly enjoy the life of wisdom.
