Public bus people flow rate counting device

Abstract

The invention relates to a public bus people flow rate counting device, comprising a signal collection device, a counting device and a central processing unit; a human body signal is collected by the signal collection device and is transmitted to the counting device by the signal collection device, the counting device is electrically connected with the central processing unit, the signal collection device comprises an infrared sending device and an infrared receiving device which are arranged in pairs and are respectively arranged on the positions of on and off doors of the public bus, close to the bottom parts of the public bus door. The public bus people flow rate counting device is mainly used for flow rate statistic of people who gets on or off the bus at each public bus stop, the bus number, the bus interval and the bus shift can be scheduled and managed according to the data which is output by the device by a public traffic center, therefore, the situation that some buses are very crowded and some buses are empty is avoided.

Description

technical field [0001] The invention belongs to the field of electronic product manufacture and application, in particular to a bus passenger flow counting device. Background technique [0002] Now more and more people take the bus, and the following situations often occur, sometimes a bus is very crowded, but the next one is very empty, and the previous bus is overcrowded and even some passengers are stranded at the bus stop , Delay everyone's commuting time. The reason for the above situation is that the bus company often only departs according to the prescribed time, and does not pay attention to the number of people taking the bus at each time period. [0003] In order to effectively carry out real-time statistics on the bus passenger flow, the following methods are mostly used at present: pressure sensor, infrared photoelectric switch, camera, bus IC card and human body infrared sensor. The difficulty of bus passenger flow lies in the irregularity of the human body pas...

Problems solved by technology

None of the above methods can avoid statistical misjudgment when used alone

[0004] The pressure sensor can only feel the pressure but cannot tell how many people are stepping on the pedal at the same time. If the human body steps over the sensor to get on and off the car, the count will be missed, and heavy objects will be mistaken for people. This method has many defects.

[0005] The algorithm after the camera acquires the signal is too complex, with a large amount of calculation and high cost

[0006] Another example is the use of infrared sensors. If the infrared sensors are installed on both sides away from the bottom of the door, it is difficult to distinguish the number of people walking side by side.
