Central host.Central host is the management and the command centre of whole city traffic signal lamp control system, and it comprises operating system and a cover centre management software.Centre management software is a visual information platform, its energy image shows the canalization and the signal lamp installation situation at each crossing, the phase place and the timing scheme of real-time demonstration/adjustment junction machine, show the duty of belisha beacon in real time, and write down the quality of all junction machines and signal lamp in the daily record mode.
The crossing main frame.A crossing has only a crossing main frame, and its major function is: adopt CDMA/GSM/GPRS mode and center machine networking, realize the networking control of whole city, realize control modes such as line traffic control, green wave band.Phase place, working method, timing scheme, the definition light color of crossing extension set (driving extension set) etc. are set.The crossing extension set to the time, reset, guarantee that the four direction extension set is synchronous.The trigger pip that reception gamma camera, radar, inductive coil are sent here realizes vehicle flowrate, signal timing dial adaptation function.In real time to center machine feedback crossing host work state and belisha beacon tool quality information.Home-confined like this, also can know the quality of all signal lamps of whole city, so that in time safeguard.
The crossing extension set.There is 1-4 driving extension set (specifically deciding on the crossing) at each crossing, and one two bit address sign indicating number of each extension set (two wire jumpers) is to distinguish the different extension sets in four orientation, all directions.Driver module includes the fine or not status information that detects every the signal lamp in crossing, feeds back to single-chip microcomputer simultaneously and send memory stores this information, sends to main frame by the extension set transceiver module again.The extension set transceiver module is responsible for receiving phase place, timing scheme, period and clock synchronizing information that the crossing main frame sends, signal lamp work state information etc.; Receive the signal lamp work state information that sends this extension set and controlled to the crossing main frame behind the feedback request signal of crossing main frame.Storer is responsible for storing the information such as phase place, timing scheme and period that the crossing main frame is sent.Clock chip is responsible for date timing and synchronous.Single-chip microcomputer is the core of crossing extension set, is responsible for coordinating the work of each module, is responsible for transferring signal lamp timing scheme from storer, opens 15 way switch driving circuits by the timing scheme then, controls the light on and off of different light color signal lamps.The work of extension set transceiver module is held frequently and is adopted 400MHZ.
Photovoltaic panel (polysilicon solar cell plate) is an electric energy with conversion of solar energy, and to crossing master/extension set and signal lamp power supply, unnecessary energy is by the solar cell accumulation of energy through the charging change-over panel.Solar cell is sunny, during energy surplus as energy storage means; It is the energy supply device for the rainy weather of sunlight deficiency.The charging change-over panel is the center bridge of power unit, and when sunny, the electric energy of photovoltaic panel (polysilicon solar cell plate) conversion is through the charging change-over panel, and a part is to crossing master/extension set and signal lamp power supply, and a part is given rechargeable solar battery; When sunlight is not enough, by solar cell for supplying power; Sun power and battery automatically switch to the alternating current 220V power supply when all not enough, charge the battery simultaneously.
The self-adaptation part: system leaves abundant interface, can earthing inductor, video triggers and the video radar combines triggering mode.The ground inductive coil is accurately stable, is not subjected to the influence of weather and light, but construction is inconvenient relatively; Video triggers convenient, but is subject to the influence of weather and light, so the native system triggering mode that adopts the video radar to combine.
Because what this system adopted is sun power, sun power is the inexhaustible energy, energy-conserving and environment-protective.Can solve the ubiquitous practical problems of present signal lighting control system well.(1) safety problem.System works voltage is direct current 12V, is the low-voltage safety operating voltage, the electric shock accidents in the time of can not having original use alternating current 220V voltage.(2) power issue.Because system adopts sun power as main working power, alternating current is only as accessory power supply, thereby system's interference that will no longer be had a power failure, need not purchase " it is precious to have a power failure " of poor efficiency more in addition, even the rainy weather that has a power failure, also operate as normal can also be longer more than 7 days continuously in system.(3) underground pipeline construction maintenance issues.A crossing drives extension set by 1 crossing main frame and 1-4 crossing and forms, not only wireless mode is adopted in the communication between crossing main frame and the crossing extension set, and the communication between central host and the crossing main frame also is to adopt wireless mode, thereby need not cross road and bury underground utilities, construction is difficult safeguards difficult problem thereby solved.(4) networking problem.System adopts the CDMA/GSM wireless network card, need not pipeline construction with rent, need not buy expensive fiber optic equipment, not only economical and practical, and signal is good, it is wide to distribute, non-blind area.One apart from the center 5 kilometers crossing, the expense that only networks just can be saved more than 300,000 yuan, and a new system is less than 300,000 yuans.(5) adaptive problem.The crossing host function is powerful, the embedded main board of stable performance, and abundant interface is arranged.The induction mode that system adopts radar to combine with video has overcome the deficiency of pure video mode, inductive coil.(6) signal lamp detects problem.System is provided with special light fixture state detection module, detects light fixture quality status information in real time, and gives central host information feedback in real time, like this " home-confined, as also to know all over the world ".(7) energy-conserving and environment-protective.System adopts green energy resource-sun power, almost need not AC power, need not go again to buy expensive " it is precious to have a power failure ".If by degree zooming crossing every days 20, but 60 crossings 1 year using electricity wisely 20 * 60 * 365=438000 degree then.
Long service life, the life-span of sun power energy-absorbing plate is generally all more than 20 years.
