Description

The wireless signal lamp controller

Technical field

The utility model relates to a kind of Traffic signal control product, particularly relates to a kind of wireless signal lamp controller.

Background technology

In recent years, high speed development along with China's economic, people's living standard is more and more higher, family-sized car is come into rapidly huge numbers of families, this gives road has currently increased huge pressure, particularly in city, without Road how to improve, city is as He Jianshe, but traffic is more and more blocked up, in order to solve and to delay current pressure, traffic department improves constantly the management level of road, to bring into play to greatest extent the traffic capacity of road, the important measures that wherein the chain control of Multiple Intersections traffic signals improved just road passage capability.The chain control of Multiple Intersections traffic lights need to adopt communication to realize, substantially by wiring, realizes at present, and it is a lot of that this can make the cost of construction increase, and a small amount of employing GPRS communication is also arranged, but equipment cost is high, and needs operating cost.Here provide a kind of wireless signal lamp controller, adopt the mode of 470MHZ wireless self-networking communication, realize the chain control of Multiple Intersections traffic signals.The installation of system and equipment cost are all very low, and construction is simple, convenient, without operating cost, more are applicable to our national conditions.

The utility model content

The purpose of this utility model is to provide a kind of new wireless signal lamp controller.

For achieving the above object, technical solution adopted in the utility model is as follows: the utility model wireless signal lamp controller comprises central processing unit, timing module, traffic controller module, power module and wireless RWNS communication module, and described central processing unit is electrically connected to timing module, traffic controller module, power module and wireless RWNS communication module respectively.

Compared with prior art, the beneficial effects of the utility model are: the utility model wireless signal lamp controller transmits data by the mode of wireless self-networking, and the installation cost of system is lower, and construction is simple, convenient, and do not need running cost, more be applicable to China's actual conditions.The utility model can adopt the Wireless Network transmission of information, realizes the transmission of data, reaches the chain control of Multiple Intersections traffic lights; The wireless signal lamp controller can carry out the control signal lamp according to the signal lamp control law of pre-stored different periods, arrives the purpose of adjust flux, Multiple Intersections jointly control the wait that can reduce people's red light, guarantee the best traffic capacity of road.The utility model construction is simple, easy for installation.

The accompanying drawing explanation

Fig. 1 is structural representation block diagram of the present utility model;

In figure: 1. central processing unit, 2. timing module, 3. traffic controller module, 4. power module, 5. wireless RWNS communication module.

Embodiment

Consult Fig. 1, the utility model wireless signal lamp controller mainly comprises central processing unit 1, timing module 2, traffic controller module 3, power module pressure 4 and wireless RWNS communication module 5, and central processing unit 1 is electrically connected to timing module 2, traffic controller module 3, power module pressure 4 and wireless RWNS communication module 5 respectively.

Wherein, central processing unit 1 has larger internal memory and arithmetic speed fast, is convenient to the quick realization of wireless self-networking algorithm, the optional STM32F103C8 chip of producing with ST Microelectronics.The prestore signal lamp control law of different periods of central processing unit 1, this rule can be according to the passage situation of different period pedestrians and vehicle and the current ratio establishment of all directions in the past, the general large direction of traffic volume, the service time of green light can be longer.The RP-S time measurement module that the optional Hangzhou Runpaq Environmental Technology Co., Ltd. of timing module 2 produces.The YT-T-2 relay module that the optional Hangzhou Runpaq Environmental Technology Co., Ltd. of traffic controller module 3 produces.Power module 4 provides reliable power supply for modules, can select the WA5-220S12D3 power module of liking that Pu electronics technology company limited produces.The LSDRF4717N04 communication module that wireless RWNS communication module 5 can select Hangzhou Lierda Technology Co., Ltd. to produce.

During use, at each crossing, the utility model wireless signal lamp controller is installed, traffic controller module 3 in each wireless signal lamp controller is connected with the signal lamp at crossing, place, and each wireless signal lamp controller carries out wireless telecommunications by the wireless RWNS communication module 5 of self with the line RWNS communication module 5 of other wireless signal lamp controllers.During work, can select in advance the wireless signal lamp controller at a crossing as standard time point control device, and by wireless time corrector (the RW-T type wireless device time corrector that can select source, Hangzhou board science and technology equipment company to produce) during to this wireless signal lamp controller school.Central processing unit 1 is accepted the standard time of wireless time corrector by RWNS communication module 5, central processing unit 1 is assigned to timing module 2 to this standard time, timing module 2 starts timing (timing module 2 is one group of accurate elapsed time clock), produces a standard time identical with Beijing time.The standard time that central processing unit 1 regularly reads timing module 2, send to the RWNS communication module 5 of other wireless signal lamp controllers by RWNS communication module 5, make the timing module 2 of each wireless signal lamp controller obtain the identical standard time, timing module 2 time synchronisations of each wireless signal lamp controller.When the chain control of each belisha beacon is started working, the user is converted to the mistiming (the crossing control of staggering the time by the distance of adjacent signals lamp according to the normal travel speed of vehicle, reduce the stand-by period of red light), send to each wireless signal lamp controller by wireless time corrector.The central processing unit 1 of each wireless signal lamp controller adds according to the signal lamp control law prestored the mistiming control signal lamp that the adjacent intersection signal lamp is controlled, thereby realize the chain control of Multiple Intersections signal lamp, when vehicle travels by normal speed, can reach smooth the way, reduce the stand-by period of red light, the traffic capacity of road is improved greatly.Deviation appears when preventing the timing module 2 long-time timing of indivedual crossings wireless signal lamp controller, selected standard time point control device can be regularly (inferior/hour) sends to the RWNS communication module 5 of other wireless signal lamp controllers by RWNS communication module 5, make timing module 2 timing alignments of each wireless signal lamp controller, obtain the identical standard time, guarantee the synchronism of each chain control in crossing.
