Description
Technical field
The present invention relates to wireless communication technology and traffic lights control and management technology.
Background technology
The control management system of present domestic city intersection traffic lights, generally use the mode of road junction machine (switch switch board) control and management, promptly at each, or several crossing is installed a road junction machine and is come the traffic lights at this one or several crossing are carried out centralized control.The switch of each signal lamp at traffic lights crossing all is placed in the machine rack of road junction, and in ideal conditions, these road junction machines will link together by optical fiber or other telecommunication cable, lead to the urban traffic control center.
There are the following problems for existing control system:
1. owing to use a road junction machine, come all traffic lights at whole traffic lights crossing are carried out centralized control, thereby, the power lead of each signal lamp all must go out from the road junction power traction, like this, the quantity of the power lead that each road junction machine is drawn will be a no small number, and will be particularly all the more so by the situation that a road junction machine is controlled several crossings.The power lead of these numerous numbers not only needs to spend more material, when laying installation, need carry out road " cutting open the chest to cut open tripe ", very influences traffic, and all very inconvenience of repair and maintenance.
2. because the cost of road junction machine is higher, and installation workload is bigger, the traffic intersection of new expansion often cannot in time be installed the road junction machine, thereby usually produce some unnecessary traffic hazards in many cities; Under unavoidable situation, have to use interim electronic police to substitute.And electronic police has not only taken passing road to a certain extent, and needs charging at any time and special messenger's keeping, and it is very inconvenient to use.
3. because the fast development in city, in many places, since a variety of causes, the pre-buried required communications cable of all failing.For the road junction machine with entire city links together and the road that has built up in the city is excavated again, to lay the communications cable, it will be a very difficult thing, thereby, many road junctions machine is actually working alone of " each man fight all by himself " formula, not networking, this is undoubtedly a great problem to realizing the modern management of entire city traffic.In addition, the reconstruction of road, enlarging, even situation about planning again, very general in China, thereby it is flexibly a kind of that market in urgent need is wanted, and is convenient to the wireless traffic signal light control management system that moves and install.
4. in particular cases many, the traffic hazard that for example happens suddenly, the state guest is visiting etc., all needs traffic police on duty, change the mode of operation of traffic lights, and existing systems obviously can not satisfy this demand temporarily.
5. in addition, because the fast development of science and technology, what original traffic lights used is the big incandescent lamp of power consumption, what the now traffic lights generally used is the light emitting diode of low-power consumption, people begin to consider to utilize the new energy such as sun power and wind energy, replace the mode of traditional laying cable power supply, obviously, mode by all signal lamps of machine centralized control crossing, old-fashioned road junction can not satisfy this new needs.
In sum, existing Traffic Signals in Urban Roads lamp control system is not only bulky, complex circuit, construction cost and maintenance cost are all very high, and use also very inconvenient, obviously the needs of economy and city fast development can not have been caught up with, the reality that can not adapt to scientific and technical fast development, an economical and efficient is wanted in market in urgent need, easy to use flexible, installation and maintenance is simple, and can adapt to urban transportation modern management needs, the traffic lights control management system of a new generation.
Summary of the invention
Technical matters to be solved by this invention is exactly the defective at existing traffic lights control management system, and the needs of urban transportation modern management, provides a kind of brand-new, the wireless traffic signal light control system of economical and efficient.
The present invention solves its technical matters, and the technical scheme of employing is:
One. basic structure:
Use one, or a plurality of dispersion is installed on the different directions of same crossing, highly integrated signal lamp control module replaces whole belisha beacon is carried out central controlled road junction machine; Utilize the mode of radio communication to coordinate again, make the control module of these dispersions, can command the work of all signal lamps of crossing jointly in harmonious ground, and, be connected with the urban traffic control center by wireless or wired mode.
Two. the system works principle
At first, we are on each direction of traffic lights crossing, each that need control or one group of traffic lights place, an independently traffic signals lamp control module (being called for short control module later on) is installed, this control module is by wired mode, directly be connected with this or this group traffic lights, and take charge this or this organize the work of traffic lights, shown in figure one.
This individual control module is made up of a radio receiving transmitting module and corresponding signal lamp switch control circuit; This radio receiving transmitting module in the control module, normally highly integrated by one, the wireless single-chip transceiver of the micropower that antijamming capability is strong is made the (radio communication that we will utilize the wireless single-chip transceiver of this micropower to be carried out, be called micro power radio communication, for example the communication between the Zigbee network node); This radio receiving transmitting module in the control module, it also can be a terminal module (for example existing mobile communications network of existing other large-scale wireless communication network system, the communication that we will utilize this large-scale cordless communication network to carry out, be called external wireless Netcom letter, with the micropower communication network in the difference among a small circle); Each control module all has own radio address coding.
In all control modules at each crossing, have a control module at least, it is required to store this crossing, various traffic lights mode of operations and working procedure; According to the difference of control mode, also can in all control modules, all store these mode of operations and working procedure.
These control modules will be commanded opening and closing of their each responsible separately signal lamps according to the predefined a certain mode of operation in urban traffic control center.
The traffic lights mode of operation here, be meant all signal lamps in a traffic lights crossing, for can harmonious mutually work, using under the same clock standard prerequisite, in the cycle of a variation, various fixedly the opening with the shut-in time of defined shown, it also can be at one day, or week, or in the different periods in 1 year, select for use different opening to show with the shut-in time, and all traffic lights of same crossing that form, various steady job modes in long fixedly period, each mode of operation all has a concrete numbering.
The working procedure here is meant the Single Chip Microcomputer (SCM) program that is stored in the control module, and this program will be come the switch of control signal lamp according to these different signal lamp mode of operations.This working procedure can only be selected the switch that a kind of mode of operation is come the command signal lamp at every turn from the stored a plurality of mode of operations of control module.
The urban traffic control center can by signal lamp mode of operation and the working procedure of wired mode with all needs, write these control modules in advance before these modules are installed; Also can after installing, these modules, utilize hand-hold wireless mode of operation and working procedure uploader, or portable computer write by wireless mode.
The selection instruction of each crossing concrete signal lamp mode of operation is to assign by wireless mode, and this comprises and uses wireless controller to assign at the scene, also comprises by traffic control center and assigning by wireless network.
When the signal lamp at a crossing of the common control of a plurality of control modules, these are control module independently separately, will use the mode of radio communication to carry out work coordination.
The control system at each crossing, can directly pass through existing mobile communications network, or other wired and wireless network, link to each other with the urban traffic control center, thereby managerial personnel can be controlled commander to the mode of operation at each traffic lights crossing easily.
Three. three kinds of basic control modes:
1. two-phase traffic lights crossing control mode:
When a crossing only is provided with one group of signal lamp, part two-phase traffic signal lamp system for example, system just only needs a control module that directly links to each other with this group signal lamp, at this moment, it is required that this control module stores this crossing, all traffic lights mode of operation and working procedures; The function of this control module, road junction machine just as existing signal lamp intersection, only its volume is much smaller, price is much lower, and it can also use wireless mode simultaneously, links to each other with the urban traffic control center, and use wireless mode, carry out uploading of mode of operation and working procedure, the selection and the change of mode of operation instruction, and clock is imitated the work that just waiting.
2. the wireless direct control mode at polyphase signa lamp crossing:
When making in this way, in a plurality of control modules at same traffic lights crossing, only need a control module and store traffic lights mode of operation and working procedure, this control module is exactly the Central Control Module at this crossing, and all the other control modules are sub-control module; Central Control Module utilizes the mode of micro power radio communication, to each sub-control module, directly sends the wireless instructions of each signal lamp opening and closing, directly the work of each traffic lights of commander's control crossing.At this moment, Central Control Module also is equivalent to a road junction machine, only it and being connected of each traffic lights at crossing, become the wireless connections mode from the wired connection mode in past, and each sub-control module, then only be equivalent to a wireless connections port between Central Control Module and the signal lamp, shown in figure two.
3. the wired connection at polyphase signa lamp crossing, the control mode of no line coordination:
When making in this way, each control module in a plurality of control modules at same traffic lights crossing all must store required various mode of operations and the working procedure of traffic lights that they are controlled separately.
Manage the control program of whole crossing mode of operation, controlled the switching signal of all traffic lights of crossing, and the control module on each direction of crossing, only the switching signal of several signal lamps of wherein directly being connected with it of control; Which path switching signal is which control module control, and is to distribute according to the numbering of control module, and the numbering of each control module, and is corresponding in the position at this crossing with the crossing at its place and it again.
Which kind of mode of operation when each crossing select for use, determined by the urban traffic control center fully.
Between each control module at same crossing, will be by receiving wireless clock sync signal, with wireless mode of operation selection instruction signal, coordinate the work between them, so that all traffic signals lamp control modules of same crossing, use same clock standard timing, use same mode of operation work, thereby guarantee that all signal lamps can work harmoniously.
This wireless coordinated mode divides use external wireless net to coordinate again and the micro power radio communication mode is coordinated two kinds:
A: the external wireless net is coordinated: when this wireless co-ordination is when realizing by the external wireless net, each control module at same crossing, to directly come the receive clock synchronizing signal from this external wireless net, with mode of operation selection instruction signal, and when breaking down, directly, send failure alarm signal to control center by this external wireless net; Simultaneously, each is from the urban traffic control center, and the instruction of change traffic lights crossing mode of operation is with directly passing to all control modules at same crossing, shown in figure three.
B. micro power radio communication is coordinated: when this wireless co-ordination is when realizing by micro power radio communication, in all control modules at each crossing, have at least one to be Central Control Module, all the other are sub-control module; Central Control Module has one can pass through GPS, or mobile communication terminal, or other wired or wireless mode, with a clock of traffic control center's clock synchronization; At regular intervals, Central Control Module will utilize the mode of micro power radio communication, and all the sub-control modules to same crossing are launched self clock signal, require they and this clock synchronization; In addition, when any one control module work is broken down, Central Control Module will utilize this micro power radio communication network, or the external wireless network that is connected with control center, send fault-signal to control center, shown in figure four.
The instruction of each change traffic lights crossing mode of operation, with the hand-hold wireless controller that utilizes through authorizing, or by linking to each other wired or wireless network with the urban traffic control center, pass to the Central Control Module at crossing earlier, and then by this Central Control Module, in the mode of micro power radio communication, pass to the sub-control module on this other direction of traffic lights crossing; If we are on Central Control Module, the communication terminal module of an external wireless net is installed again, we can also utilize the external wireless net, after the instruction at urban traffic control center issued Central Control Module, again by Central Control Module, by the mode of micro power radio communication, pass to other sub-control modules at same crossing; The hand-hold wireless controller here, telepilot can assigning the mode of operation selection instruction to center module exactly, it is equipped with a wireless single-chip transceiver module of the micropower identical with control module, thereby, can use wireless mode and Central Control Module to communicate.
When we adopted the working method of this " line traffic control being arranged, no line coordination ", the normal operation of system did not also rely on radio communication:
Instruction in the change operation mode that does not receive any process mandate, comprise crossing traffic police on duty because the generation of accident, and before the instruction of the temporary changes crossing traffic signal lamp mode of operation of sending, all signal lamps on all directions of traffic lights crossing, will be according to previously selected, be stored in control module that they directly are connected in a mode of operation operation, except at regular intervals, need by wireless mode, outside the transfer clock synchronizing signal, the normal operation of system does not rely on radio communication.Thereby new system has higher operational reliability than existing system.
Three. the wireless connections of system:
System and urban traffic control center be connected with following several mode:
1. external wireless net mode, when making in this way, all control module in the system, comprise the hand-hold wireless controller, the communication terminal module of an external wireless net all is installed, like this, all control modules in the system have linked together just by the external wireless net.When using this connected mode, signal lamp mode of operation and working procedure in the control module just can directly be uploaded by the external wireless net at the urban traffic control center, and needn't use wireless mode of operation and working procedure uploader to upload at the scene, shown in figure three.
2. the mode of micro power radio communication, when making in this way, all control module in the system, comprise the hand-hold wireless controller, with wireless mode of operation and working procedure uploader, a wireless single-chip transceiver of micropower all is installed, at this moment, each of traffic lights crossing sub-control module, all can pass through a closely wireless single-chip transceiver of micropower, Central Control Module with same crossing, and hand-hold wireless controller and wireless mode of operation and working procedure uploader realize communicating to connect, then, and the Central Control Module at this crossing, pass through the wireless single-chip transceiver of micropower of long distance again, link to each other with the Central Control Module of adjacent intersection, thereby, a micro power radio communication network in limited scope, formed, Zigbee network for example, and at the local network that connects the urban traffic control center that inserts easily.
3. hybrid wireless net mode, when making in this way, except control modules all in the system, comprise the hand-hold wireless controller, with wireless mode of operation and working procedure uploader, all be equipped with outside the wireless single-chip transceiver of micropower, in the Central Control Module at crossing, the communication terminal of an external wireless network also has been installed, at this moment, each of traffic lights crossing sub-control module, by the wireless single-chip transceiver of micropower closely, can with the Central Control Module at same crossing, the hand-hold wireless controller, and wireless mode of operation and working procedure uploader realize communicating to connect, and then utilize the external wireless network communication terminal in the Central Control Module, links to each other with the urban traffic control center by the external wireless net.
4. the selection of wireless network:
Characteristics at system of the present invention and city traffic signal lamp control:
When a. system moves, because all signal lamp mode of operation and working procedures, can be stored in the signal lamp control module in advance, each mode of operation all has the numbering of oneself, and each signal lamp intersection also all has the numbering of oneself, thereby, the traffic lights mode of operation selection instruction that needs transmission, only be numbering and with, thereby data volume is very limited; Simultaneously, instruction from the change signal lamp mode of operation at urban traffic control center, often can assign Central Control Module in advance to each traffic lights crossing, this instruction, certain time delay can be arranged, and the mode of external wireless net and micro power radio communication can be born this work, but the general wide coverage of external wireless net, thereby, often select the external wireless net more convenient;
B. because special circumstances such as road burst accidents, change belisha beacon mode of operation instruction from traffic police on duty must in time be assigned, any time delay can not be arranged, and existing mobile radio communication real time of data transmission can not get guaranteeing, thereby the wireless handheld controller of the mode of use micro power radio communication, directly assigning at the scene, obviously is best choice;
C. signal lamp mode of operation and working procedure data volume are bigger, transmit by the wireless network that connects the center, the flow of network will be increased greatly, the burden of emphasizer, and the general wireless single-chip transceiver of micropower is with point-to-point, or the mode of point-to-multipoint is when carrying out data transmission, speed is all than higher, if use a hand-hold wireless mode of operation and working procedure uploader at the scene, or have a notebook computer of the wireless single-chip transceiver of micropower, by wireless mode, the control module of writing direct will be very efficient and convenient;
D. thereby adopt and to utilize wireless mode of operation and working procedure uploader at the scene, by the mode of micro power radio communication, the control module of writing direct is more economical quick and rationally;
E. not only cost is low to adopt micro power radio communication in addition, and does not have operating charges.
Obviously, the wireless network in the system connects, and select the mode of micro power radio communication, or hybrid wireless net ways of connecting seems more reasonable.
Four. the writing and revising of system works pattern and working procedure:
Traffic lights mode of operation and working procedure that control module is stored, can be before control module is installed at the scene, write by wired mode, also can be after control module is installed, write by specially-enabled hand-hold wireless mode of operation and working procedure uploader, (it can be on the machine mode of operation uploader of existing road junction, adding a wireless single-chip transceiver module of micropower gets final product), also can use one to be connected with the wireless single-chip transceiver module of micropower line, through the notebook computer of authorizing, at the scene with one to one or broadcasting mode, be directly uploaded in each control module at traffic lights crossing, shown in figure five; In addition, can also utilize to connect each traffic lights crossing Central Control Module, wired or wireless network uploads in the center module earlier, and then by Central Control Module, be loaded in the sub-control module on other direction of traffic lights crossing.If use the mode of micropower communication, the control module of writing direct at the scene, the work that writes at each traffic lights crossing only needs just can finish several seconds.Equally, adopt in a like fashion, we also can upload new mode of operation or delete some old mode of operation as required.
Transceiver in the control module is in accepting state usually, so that can receive the various instructions of sending by wireless mode at any time.
Beneficial effect of the present invention:
1, because existing expensive road junction, traffic lights crossing machine, by one or several volume little (hand size), cost is low, and highly integrated control module substitutes, and this just greatly reduces the cost of system.
2, owing to control module, can be directly installed near the traffic lights group on the lamp stand of crossing, or in the box body of two-phase traffic lights.We only need the position from each traffic lights group, draw the control module of a pair of power lead to the lamp stand on the spot, directly link to each other with each signal lamp of lamp group by the control module lead-in wire again and get final product, this has just reduced power circuit, reduce material cost, simplified installation and maintenance job greatly.
3, because control module is near traffic lights, thereby power taking on the spot, it is all very convenient flexibly that resettlement is installed.And, also exempt from " cutting open the chest to cut open the belly " road breaking engineering, cross the street cable with what lay that the road junction machine is connected with traffic lights on each road direction, with and subsequent the repair and maintenance work that very bothers.This will be a very big saving.
4, utilize the present invention, urban traffic intersection in those new expansions, be easy to just can install a two-phase traffic light control system, as long as connect with the mains, just can come into operation, many more than using interim charging electronic police to make things convenient for, this will be avoided many unnecessary traffic hazards at once.
5, because existing traffic signals, changed the LED of low-power consumption into, thereby, use and wait other driven by energy such as sun power and wind energy driving, casting aside fully with the power supply of city cable power has become possibility, like this, utilize the present invention, whole traffic lights crossing will be realized real " wireless penetration " fully, and such benefit is conspicuous.
6, in addition, because traffic lights mode of operation and working procedure in the Central Control Module, can utilize notebook computer through authorizing, or other hand-held specialized equipment, adopt wireless mode, upload in the Central Control Module fast, thereby we can weave our needed various traffic lights mode of operations and working procedure in advance on computers, and are numbered, and deposit computer in, then, in the vehicle in advancing, we just can finish the work of uploading at an easy rate, and are very convenient.
7, because what the present invention used is wireless control module, traffic police on duty just can adjust the traffic lights mode of operation easily at the hand-hold wireless telepilot that uses process to authorize within the scope of authority temporarily, with reply burst traffic hazard, or other are during such as special circumstances such as the state guest are visiting.
8, because system of the present invention has adopted the wireless network ways of connecting, thereby, between the crossing of also not using telecommunication cable to connect, just can use wireless mode to connect, and insert the telecommunication cable network that has laid, this has just solved in the present city, still " traffic lights isolated island " problem owing to no telecommunication cable connection that exists, control center just can carry out remote control to the traffic lights at each crossing.In newly-built crossing and road reformation highway section, also just no longer need pre-buried and buried light pricker or cable again underground.The cost of wireless network otherwise connects much lowerly more than laying the light pricker or making, and has let alone the installation and maintenance expense.
9, though system of the present invention has used highly integrated, good confidentiality, the direct sequence spectrum spread communication module that reliability and antijamming capability are all very high, guarantee the reliability of system communication, but the usual operation of system does not rely on this wireless communication system, have only when needing to change crossing traffic signal lamp mode of operation once in a while and just use, during of short duration use, generally also only transmit the instruction of the change mode of operation of finite data, thereby system reliability is very high.
10, system of the present invention not only cost is low, less than 1/10th of the cost of original system, and installs, and maintenance management is all very convenient, and the managed operation cost is also very low.The production cost of a sub-control module is about about 200 yuans, a Central Control Module production cost also less than 600 yuans, add installation, the saving of expense such as operation maintenance and networking, each traffic lights crossing, the expense of visible direct saving just can reach ten of thousands unit.
