【Specific embodiment】
Referring to Fig. 1, the utility model is mainly made up of two parts, including be arranged on the intersection of intersection all directions without
Line signal collector and the terminal wireless server module for being arranged on traffic relevant departments, the intersection signal collector include
Movable signal module, signal processing module and signal transmission module, the intersection wireless signal are collected in the collection being sequentially connected
Collector is used for the mobile phone signal of detecting pedestrian, is wirelessly transferred to the terminal wireless server module and is connect
Receive, store and processing data.
Wherein, collection collects movable signal modular structure referring to Fig. 2, collection collect movable signal module workflow referring to
Fig. 3.
Power module：Mainly it is powered by solar energy electroplax.
Carry solar energy electroplax, battery, power management module use efficient stable solar charging/discharging control circuit for
System provides electric energy, while connecting town road, solar energy electroplax charges for battery, and battery is powered for equipment,
Rainy weather, for system is charged and is powered, allows the sufficient operation of the system energy logical by municipal circuit while energy saving
Freely.
Movable signal module is collected in collection：Received so as to carry out Regulate signal equipment by the power of Regulate signal receiver module
The scope of mobile phone signal.
Sent out by the mobile phone entrained by pedestrian in antenna and chip Real-time Collection reception the intersection waiting area of signal acquisition
The wireless signal for going out, by improving the tranmitting frequency that minimum threshold level level (ACCMIN) gathers with control signal, reduces letter
The range of receiving of acquisition module is ceased, the covering radius of requirement is reached.Pedestrian typically carries a mobile phone at present, so according to
The number of signals for detecting can just learn the number of intersection waiting area.According to pedestrian traffic behavior and psychological relevant knowledge,
Before the crossing that pedestrian is often concentrated in intersection when green light is waited.By taking Xi'an as an example, 86 intersections are entered
Row investigation, finds the size with intersection and section scale, and the scope that pedestrian concentrates can also change accordingly.But it is horizontal with people's row
4m is that radius can be with the 99% probable range covering all of pedestrian of waiting before road.
Mainly by mobile communication module (WCDMA, GSM etc.), and the corresponding scanning hardware of these signals.This module
Major function is the relevant parameter (mobile device ID, signal intensity, signal to noise ratio etc.) of detection mobile communication equipment.Signal is received
Scope it is mainly related to the factor such as transmitting power of equipment, minimum threshold level, antenna height, feeder loss, antenna tilt.Hair
The adjustment for penetrating power can be by adjusting parameter control channel base station effective power (BSPWR), non-control channel base station Effective power
Rate (BSTXPWR), control channel transmitter power (BSPWRB), non-control channel transmitter power (BSPWRT) are realized.Together
When, minimum threshold level level (ACCMIN), the minimum received signal level allowed by equipment, when the reception of equipment is believed are set
During number less than minimum threshold level level, the transmission signal of mobile phone will be can not receive.
Signal processing module：Pedestrian's street crossing holding areas can generally also have that part walk about by pedestrian herein but
Non- is waiting green light person.Corresponding signal identification is positioned by signal detection module, at the same time tracer signal is fixed each time
The time of position.
Signal processing module does to the signal that previous stage collects and judges, main purpose is to recognize that previous step is received
Whether signal is that waiting area waiting green light pedestrian sends.According to traffic rule, pedestrian can be in static shape when green light is waited
State or displacement amplitude change a kind of little state.It is bigger than normal than actual holding areas due to set signal range of receiving, to obtain
Really and accurately data are taken, it is necessary to reject some data, such as the approach in road roadside pedestrian herein or during green light it is logical from this
The signal that the pedestrian for crossing is launched.The utility model is using this index of pedestrian's speed as according to the screening for carrying out data.
According to the U.S.《Traffic capacity handbook》, the average walking speed of typical crowd is 1.2m/s, it is contemplated that old man with it is small
Child's walking speed is relatively low, while pedestrian's translational speed when green light is waited is very low, the utility model uses walking speed 1.0m/
S is differentiated that is, speed is to be considered that this signal is in waiting state less than 1.0m/s as threshold value accordingly.
The built-in GPS location of signal processing module, positions to each movable signal, while what record was positioned each time
Time and signal location.The signal of waiting area is obtained by previous step signal collection module, thus can be by the signal of same frequency
Matched, obtained signal-gps coordinate.By the positioning twice to same signal and the time interval for positioning every time, root
According to formula：
Wherein, S：Represent the horizontal displacement for positioning point-to-point transmission twice, unit m；t:The time difference that expression is positioned twice, Δ t
=tn-tn-1, unit s；V：Represent pedestrian's speed, unit m/s；Draw the translational speed of each signal, i.e. pedestrian walking speed.
Described signal framing, is mainly positioned by GPS, and gps data is carried out into phase with the data of signal acquisition
Matched with ID, while GPS and signal picker to be received the system time alignment of data, gps data is entered into row interpolation, so just
GPS- signal coordinates can be obtained, wireless signal data are corresponded with its gps data.
Signal transmission module：Signal is carried out by AD conversion chip be processed and converted to data signal, the utility model
Using current widely used successive approximation type A/D converter, while using the high-quality waveform coding of two-forty, the allusion quotation of coding
Type speed is 16kbps.Then data signal is carried out into channel decoding, becomes suitable for the pattern of transmission.Final data passes through
It is sent wirelessly to terminal.
Signal transmission module includes the parts such as converter, amplifier, wave filter, encoder, modulator, multiplexer.It is described
Signal transmission module, carries out being processed and converted to data signal by AD conversion chip to signal, and the utility model is using current
Widely used successive approximation type A/D converter, while using the high-quality waveform coding of two-forty, coding typical rate is
16kbps.Then data signal is carried out into channel decoding, becomes suitable for the pattern of transmission.Final data is wirelessly
Send to terminal.The transmission of wireless signal is with reception referring to Fig. 5.
The signal transmission module, analog signal turns into binary data signal after AD conversion, and it has anti-interference
Ability it is especially strong, noiseless accumulation such as is easy to store, process and exchange at a series of features.
Terminal wireless server module is used to receive signal, the work such as row decoding of going forward side by side, demodulation and data preparation.Pass through
Computer, can be recognized with the related data of each intersection of real-time monitored various regions, relevant department according to these data informations
Whether the situation of each intersection, judge intersection signal timing rationally and as the foundation of adjustment, with intelligent transportation
Development is also used as the capsule information of remote control and regulation intersection.
Above content is only explanation technological thought of the present utility model, it is impossible to limit protection model of the present utility model with this
Enclose, it is every according to the utility model proposes technological thought, any change done on the basis of technical scheme each falls within this reality
Within protection domain with new claims.
