Specific control flow may refer to Fig. 3, make a concrete analysis of as follows:
Each module initialization is completed first, reads configuration documentation, completes the parameter configuration of each module, and starting carrys out car test and surveys mould
Block, camera management module, traffic light status management module, network information management module.Monitor supervision platform and traffic light control system
System establishes TCP/IP connection by WIFI network, completes the encoding and decoding using data and the parsing of business.Traffic lights management module
The mode that local traffic lights is set is instructed according to monitor supervision platform, and traffic lights are controlled by RS485.Traffic light control system simultaneously
The real-time status of traffic lights is broadcast to the traffic participant of surrounding by wireless short wave communication apparatus.
Intelligent traffic signal lamp control system informs that surrounding traffic participant is real-time by broadcast traffic lamp status information
Traffic light status, applied to early warning application in green wave speed guidance and early warning application of making a dash across the red light, use the deflation of ASN1
Coding rule carries out encoding and decoding, supports different types of wireless short wave communication apparatus, settable broadcasting frequency power information etc..
In the traffic light status data of broadcast, different traffic lights ID correspond to different crossings and lane on map.Other friendships
Logical participant searches the traffic lights ID at lane end crossing by cartographic information, then the broadcast message by receiving finds the road
The traffic light status information of mouth.State (such as red light phase, the blue flash that traffic light status information will will include each traffic lights and possess
State), and (the next opening time of such as red light, next continues often information, the end time at the time of including each state
Deng), so that traffic participant, which does not have to calculate, to reduce calculating consumption directly using the data of traffic lights broadcast.
Between intelligent traffic signal lamp control system and monitor supervision platform use TCP/IP network protocol, information reception with
It is handled in processing using multithreading readjustment, oncurrent processing ability with higher has the reconnection function that goes offline.With server
It include frame head, data length, control code, command code, data field, serial number, check value, end using in data interaction agreement
Symbol.
Its lieutenant colonel's control code, command code are for determining current service type.Service type includes traffic lights registration, traffic lights
Heartbeat reports, inquires traffic light status, setting traffic lights mode, traffic light status is arranged, setting traffic lights restarts, reports traffic
Lamp status information reports vehicle detecting information, reports exception information.
Check value is used for the integrality of detection data frame.Serial number is sending information for managing the information for needing response
Afterwards, if not receiving the response message with identical control code and serial number, it will carry out repeating transmission to the information.Data field makes
With json encoding and decoding, different data informations is had according to different service types.
Carry out vehicle detection module and is mainly responsible for the vehicle fleet size for detecting current camera head monitor region.If current traffic lights are
Morphotype formula, then detection module is opened, and the module is in close state under other modes.Under dynamic mode, module can check camera shooting
Head state reports monitor supervision platform camera exception information and is switched to time mode if camera is abnormal.It is normal in camera
Under state, module understands the number of vehicles in analysis detection video, reports monitor supervision platform current when number of vehicles increases or decreases
The vehicle count information in region.Carry out flow chart such as Fig. 4 of car test survey.
In the control flow of the present embodiment, MANUAL CONTROL mode, dynamic control model and time control mould are specifically included
Formula.
In MANUAL CONTROL mode, the state for the instruction control traffic lights that traffic lights can be issued according to monitor supervision platform.Traffic
Lamp can open the state received, simultaneously close off other traffic light status.State change after the completion of, traffic lights will report whether
It changes successfully.
After it is time control model that current mode is changed in the instruction for receiving monitor supervision platform, traffic lights meeting basis is received
Cycle information, the duration of the states such as control red light, green light, amber light, and loop play.After light color change, if changing successfully, on
The current light color of server is reported, reports traffic lights exception information if failure.
After the dynamic control model that control mode switch is, system whether can be had according to camera head monitor region vehicle come
Control traffic lights.If vehicle occurs in monitoring area, the traffic lights being arranged on cross street is red light；If monitoring area is without vehicle
The traffic lights that can be then arranged on cross street are green light or yellow sudden strain of a muscle；Traffic lights, which is arranged, if all vehicles have been walked, after postponing is
Green light.Wherein, after receiving dynamic mode change information, traffic lights, which can be opened, carrys out vehicle detection module to cooperate dynamic mode.It is dynamic
The prevailing scenario of morphotype formula is suitable for fire station entrance, parking lot entrance etc..
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
