Side passenger loading is got off；According to doorway side passenger loading or gets off and doorway side passenger loading or gets off,
Count number of people in car.
By taking the first detector of doorway side as an example, when unobstructed (when such as nobody passes through), the first signal receiver
The signal for not receiving the signal of the first signal projector transmitting or receiving is very faint (being less than certain threshold value), is considered as nothing
Effect, it is " 0 " that state value, which can be arranged, according to preset rules in processor.When someone passes through, the first signal receiver receives people
The signal being reflected back, then it is " 1 " that state value, which can be arranged, according to preset rules in processor, i.e., for the first detector, when
When someone passes through, the complete change procedure of state value is：0 → 1 → 0, this represents the first detector and completes primary triggering.It is similarly right
In other 3 detectors, if also there are one such state value change procedures 0 → 1 → 0, primary triggering is also completed.
After completing primary triggering, it can wait for into next trigger process.By taking Fig. 4 as an example, the first detector is than the second detector elder generation
Complete primary triggering, i.e., processor first receives first detection signal, then is considered as and gets off, otherwise to get on the bus.Processor is according to judgement
The up/down vehicle of passenger is as a result, calculate interior specific number.
In addition, in the present embodiment, by taking the first detector as an example, since signal projector and signal receiver are arranged same
Side, signal receiver needs are judged according to predetermined threshold value, if received signal intensity is less than predetermined threshold value, then it is assumed that be
Invalid reflection signal, ignores, if meeting predetermined threshold value, illustrates it is effective reflection signal, and then send to processor
Detect signal.
Specifically, the first detector is specifically used for meeting in the intensity of the first signal receiver received signal pre-
If when threshold value, determining the signal for first signal projector transmitting for receiving reflection.
Second detector, specifically for meeting predetermined threshold value in the intensity of the second signal receiver received signal
When, determine the signal for the second signal transmitter transmitting for receiving reflection.
Third detector, specifically for meeting predetermined threshold value in the intensity of the third signal receiver received signal
When, determine the signal for the third signal projector transmitting for receiving reflection.
4th detector, specifically for meeting predetermined threshold value in the intensity of the fourth signal receiver received signal
When, determine the signal for the fourth signal transmitter transmitting for receiving reflection.
For only there are one such case when passenger's up/down, in region placed in the middle, both sides receive for the position of possible passenger
The signal strength that device receives may be close to, and in this case, can be pre-configured in two opposite signal receivers and receive
When the signal strength difference arrived is less than preset value, handled by wherein side detector.Such as third signal receiver and
The signal strength difference that one signal receiver receives is less than preset value, is handled by the first signal receiver.
In addition, being further described below：Signal projector in the application first modulated signal and then can emit letter again
Number, wherein modulated process mainly by raw modulated signal in specific coded modulation to certain carrier frequency, then should
Modulated signal sends infrared signal with certain power drive infrared emission device.
Why it is modulated primarily to the signal launched is avoided to be done by clutter noises such as extraneous infrared rays
It disturbs.Above-mentioned specific coding can customize, and can be specifically adjusted according to actual conditions, or simple or slightly complicated.
Correspondingly, signal receiver can demodulate the signal received.Demodulation is mainly modulated by what is received
Signal is decoded as can recognize that coding information as defined in preset protocol.
After specific coding is modulated, signal projector and receiver in same detector can realize one-to-one correspondence, i.e., originally
The signal that transmitter in detector is emitted is only capable of being received and recognized by the signal receiver in same group, can prevent in this way
It is interfered with each other with other detectors, improves precision and accuracy.
It should be noted that for there is the scene of 4 detectors, if car door mouth is equipped with intermediate isolating band, does not shunt
Railing or other lattice gear etc., transmitter and receiver can also be oppositely arranged, i.e., set-up mode as shown in Figure 2 is held
Row, the application are not limited.Alternatively, the different scenes such as doorway region does not have step, railing for not shunting, may be used difference
Layout, if signal projector, signal receiver are also disposed in the top in compartment, rather than side of car door etc., the application is equal
It is not limited.

Many buses at car door there are one step, when passenger getting on/off, body there are one the process for rising or reducing,
So the layout certain spacing not only to be considered of detector, it is contemplated that certain angle.As shown in figure 5, the first inspection
Certain angle can be had by surveying between device and the second detector, and but not limited to this, can be adjusted according to concrete scene.
In a kind of embodiment, after starting and detecting, signal projector emits modulated signal by preset condition, simultaneously
Signal receiver also begins to work, and signal receiver can receive modulated signal and can complete to demodulate.
For in such a way that transmitter and receiver are oppositely arranged, processor can also be sent to by demodulating successful signal,
Processor can set state according to preset rules and the signal received, such as receive the successful signal of demodulation, if " 1 "；
If there is blocking (such as passenger) between signal projector and signal receiver, signal receiver cannot receive modulated letter
Number, then detection signal is sent to processor, processor sets another state, such as sets " 0 ".
Correspondingly, the one-shot change of state experience " 1 → 0 → 1 ", the primary triggering of id signal receiver, in this system
Then mean there is passenger to pass through corresponding detector.
On the basis of the above embodiments, the detector in system does not need to be detected always, general only to need
Bus arrival is detected in the case of having passenger or more, then can be by the car door opening of vehicle come detection trigger, i.e.,
Start detection when opening car door, signal projector emits the signal modulated.
