The number monitoring principle of the passenger that gets on the bus of the present invention is as follows:

When get on the bus passenger loading time, can pass in the induction range of infrared distance sensor B and C, get on the bus to this moment of induction the earliest of passenger of infrared distance sensor B is designated as T1 (passenger that namely gets on the bus enters the induction range of infrared distance sensor B), and get on the bus to this last induction moment of passenger of distance measuring sensor B is designated as T2 (passenger that namely gets on the bus leaves the induction range of infrared distance sensor B); Get on the bus to this moment of induction the earliest of passenger of infrared distance sensor C is designated as T3, and the infrared distance sensor C passenger that gets on the bus to this finally responds to the moment and is designated as T4;

According in the present embodiment, infrared distance sensor B and infrared distance sensor C installs in the same horizontal line, and can show that both dislocation distances are 15cm, the computing formula can deriving passenger's upper half of human body average thickness δ 1 is thus as follows:

Wherein, the δ 1 upper half of human body average thickness that is the passenger that gets on the bus.

Next, can judge whether human body attitude when getting on the bus passenger loading normally (such as sequentially gets on the bus one by one by δ 1, or single lean to one side to get on the bus or crowded get on the bus simultaneously or embrace a child get on the bus), thus obtain and simply, exactly the quantity of the passenger that gets on the bus added up.Get the single human body average thickness reference value δ 0=18cm that statistics obtains, obviously when the body thickness δ 1 of the passenger that gets on the bus is less than or equal to 18cm, can represent that single passenger normally gets on the bus, body thickness δ 1 is greater than 18cm, can represent that the passenger that gets on the bus gets on the bus extremely, exist and singlely lean to one side to get on the bus, crowded get on the bus simultaneously or embrace the situations such as a child gets on the bus, need to judge passengers quantity further.

Now, need the passenger load weight W11, the W12 that get on the bus that gather within T1 ~ T2 time period and T3 ~ T4 time period of each induction according to the pressure transducer of upper objective door, the passenger load weighed average W1=(W11+W12)/2 got on the bus when obtaining each induction, calculate the ratio of the single weight threshold W0 (45kg ~ 60kg can be got) of W1 and setting, as δ 1< δ 0 or as δ 1> δ 0 and W1/W0 >=3 time, the described passengers quantity of getting on the bus at every turn sensed is 1; As δ 1> δ 0 and 1≤W1/W0<3 time, the described passengers quantity of getting on the bus at every turn sensed is 2.

In like manner, the number monitoring of the passenger of getting off of the present invention can complete according to monitoring identical method with the number of the above-mentioned passenger that gets on the bus.

Guest flow statistics about passenger's total number of persons and bus station: when upper, the passenger that gets off enters on bus respectively, the passive infrared sensor F of get-off door, after in the induction range of G, passive infrared sensor F, G outwards exports high level, what then the corresponding increase of the counter unit of control module or deduct sensed at every turn is upper, to get off passengers quantity, and the volume of the flow of passengers of this bus station is added up (namely go up, to get off passengers quantity sum), control module drives real-time patronage in display module display current bus simultaneously, namely the collection of bus passenger quantity is achieved, when passengers quantity in bus exceedes regulation passenger load quantity, then control module drives display module, the overload of display bus passenger number, and drive voice cue module to send audio alert, voice message public transport number overloads, driver can be closed and be closed objective door.
