Urban rail transit barrier-free passage system and its implementation method

Abstract

The invention discloses an urban rail transit barrier-free passage system and an implementation method thereof. The bluetooth signal is received through a bluetooth intelligent communication tool, and the bluetooth position of the object to be passed is obtained according to the signal strength and the bluetooth space position information; The data of sensors and gyroscope sensors realize the prediction of the horizontal and vertical orientation angles of the trajectory of the passing body, obtain the step frequency of the passing body, and realize the calculation of the step length of the passing body; finally, according to the Bluetooth position and sensor information, Use the extended Kalman filter to fuse these data to obtain the position of the object to be passed. When the position of the object to be passed enters the working range of the face recognition module, use the face recognition module to obtain and compare information, and control after verification The gate is opened to realize barrier-free passage in rail transit buildings. It is especially suitable for temporary entry of specific groups of people such as staff and partners in rail transit buildings. The operation is convenient and safe.

Description

technical field [0001] The invention belongs to the technical field of intelligent rail transit transportation, and in particular relates to a barrier-free passage system for urban rail transit and an implementation method thereof. Background technique [0002] In recent years, more and more cities have favored rail transit with many advantages such as large capacity, fast speed, high efficiency, and low energy consumption. Domestic urban rail transit has entered a period of rapid development, and many cities have formed networked operations. pattern. With the expansion of the scale of the urban rail transit network, the staff required for the operation and management of the urban rail transit will inevitably increase. A large number of staff are distributed in the stations, depots, office buildings and other facilities of the urban rail transit network , Different areas of these building facilities are separated by access control or gates. If staff want to pass through dif...

Problems solved by technology

However, the current distance is limited to less than 10cm whether it is the card swiping at the gate or the access control system. The card swiping process needs to be close to the card swiping machine, which will waste a certain amount of time and the efficiency needs to be improved

Moreover, the card swiping system recognizes the card but does not recognize the person, which cannot ensure that the card owner and the person who swiped the card are the same person, which is not conducive to the operation and management of urban rail transit

In addition, except for the staff of urban rail transit, when the leaders of the superior department come to inspect or the leaders of other departments at the same level come to communicate, the method generally adopted is for the staff to swipe their cards uniformly, and the system cannot accurately identify every passing person. leaves nothing to be desired
