Description
Technical field
The present invention relates to intelligent traffic light field more particularly to a kind of wireless intelligent traffic lamps based on satellite positioning coordinate
And receive the navigation device of wireless traffic modulating signal.
Background technology
At the parting of the ways, four sides all suspended on red, yellow, and green traffic lights, it is noiseless " traffic-police ".
Traffic lights are the traffic lights of international uniform.In intersection, the vehicle that several directions are come all collects here, and some is straight
Row, what is had will turn round, and on earth whom allow to get ahead, and here it is traffic lights to be accepted commanders.When red is forbidden keeping straight on or turn left,
It does not interfere under pedestrian and vehicle condition, vehicle is allowed to turn right；Green light permits vehicle straight trip or turning；It is alert when amber light flickers
Vehicle is accused to reduce speed now.It, can be with if driver can obtain the status information of crossing traffic lamp in advance the coast is clear the case where
Anticipation is made in advance, improves traffic efficiency.In the case of traffic congestion, comes subsequent vehicle driver and often do not see traffic lights
Variable condition, can only judge according to the state of preceding vehicle, can not be safely and fast pass through crossing.Existing vehicle mounted guidance
Instrument or cell phone application can provide real-time road information, but including real-time traffic light status and not change to down
The specifying informations such as the time of one state.Therefore, either in the case where the road is clear or blocks up, driver can not shift to an earlier date
Know the traffic light status of junction ahead, Driving Decision-making cannot be made in advance, makes the reduction of road efficiency.
Number of patent application CN200820095492.7, patent name are the Chinese utility model of " traffic signal display system "
Patent application discloses a kind of traffic signal display system, and emitter is arranged near traffic lights, which can obtain
It takes the traffic signals of traffic lights and makees orientation wireless transmission；Reception device is set on the automobile of user, the reception device with
Wireless mode obtains the traffic signals of the emitter transmitting and comes out traffic signal display, keeps driver more clear
Know traffic light signals.However, the wireless signal distance that common wireless launcher can emit is limited, such as commonly
The signal transmission distance of household radio router is about 30 meters, if it is desired to which long transmission distance then needs very big transmitting
Power, it is higher to the configuration requirement of wireless signal transmission system, while having a certain impact to surrounding enviroment.Therefore in traffic congestion
In the case of, it is difficult effective wireless signal for obtaining crossing and transmitting to come subsequent vehicle, still can not timely make driving and determine
Plan.
Explanation of nouns：
Satellite positioning：Global position system is a kind of technology that something is accurately positioned using satellite, it is from initial
Positioning accuracy it is low, cannot position in real time, be difficult to provide timely navigation Service, develop to present high-precision global location
System (GPS, Global Positioning System), any point can observe simultaneously at any time, on the earth
4 satellites, to realize the functions such as navigation, positioning, time service.Three-dimensional navigation is the premiere feature of GPS, aircraft, steamer, Ground Vehicle
And pedestrian may be by GPS navigation device and navigate.Auto-navigation system is on the basis of global position system GPS
The new technique to grow up.Auto-navigation system is by GPS navigation, self-contained navigation, microprocessor, vehicle speed sensor, top
Spiral shell sensor, CD-ROM drive, LCD display composition.GPS navigation system and electronic map, radio circuit, calculating
Rolling stock management information system is combined, and many functions such as vehicle tracking and traffic administration may be implemented.Chinese Beidou satellite
Navigation system is made of 3 satellites, wherein 2 are operational satellites, 1 is backup satellite；Purposes is dual-use.First two are defended
Star was respectively at 2000 and successful launch in 2003.On December 27th, 2012, Beidou satellite navigation system commencement of commercial operation.
Wireless repeater：Wireless repeater in a network, can simple narrow sense say be wireless access node (AP,
AccessPoint), the hub or switch being equivalent in cable network.But, this is one and has wireless signal transmission work(
The hub of energy, it can provide a dialogue joint for more radio networking devices.Briefly AP is exactly in wireless network
Extended line, repeater, amplifier.Play the role of reinforcing signal, extend distance.
Wireless distribution system：WDS, Wireless Distribution System, function act as wireless network
Repeater allows it that can extend extended wireless signal, to which covering is wider more by opening WDS functions on wireless router
Big range.Plainly WDS can exactly allow by wirelessly being bridged (relaying) between wireless aps or wireless router, and
The function of its wireless device coverage effect is had no effect on during relaying.We can use two wireless devices in this way,
It allows between it and establishes WDS and trust and communication relations, to which wireless network coverage is expanded to original one times or more.
WI-FI：It is a kind of technology for allowing electronic equipment to be connected to a WLAN (WLAN), it is usually used
2.4GUHF or 5G SHF ISM radio frequency bands.It is typically to have cryptoguard to be connected to WLAN；But it can also be opening
, allow for any equipment within the scope of WLAN that can connect in this way.WI-FI is the product of a wireless network communication technique
Board is held by Wi-Fi connection.Purpose is the intercommunity improved between the Wi-Fi product based on 802.11 standards of IEEE.
Someone is known as Wireless Fidelity the LAN of 802.11 serial protocols of IEEE is used.WI-FI is even equal to wireless the Internet
Network (WI-FI is the important component of WLAN).
FM frequency modulation technologies：Frequency Modulation are a kind of broadcast technologies being in daily use, can be by voice signal
High-fidelity is broadcast out, the function that portable navigation device all emits with FM substantially now.
BluetoothIt is a kind of wireless technology standard, it can be achieved that fixed equipment, mobile device and building
Short-range data between personal area network exchanges (using the UHF radio waves of the ISM band of 2.4-2.485GHz).Bluetooth skill
Art was initially formulated by telecommunications giant Ericsson in 1994, was the alternative solution as RS232 data lines at that time.Bluetooth can
Multiple equipment is connected, the problem of data synchronization is overcome.
