Detailed description of the invention
The invention will be further described with specific embodiment with reference to the accompanying drawing:
Fig. 1 is structure principle chart of the invention.
Specific embodiment
It is all the problem of timing conversion traffic lights are shown based on current mobile traffic lamp, the present invention passes through GNSS system and receives
The accurate UTC(universal time coordinated Coordinated Universal Time(UTC)), UTC matches the temporal information of traffic lights always, can
Accurately to control the time that traffic lights shows content, the time control solar panel that can also be provided according to UTC is according to UTC
Rotary head is controlled, the irradiation of sunlight is received with maximum receiving plane, provides currently shine upon lower maximum charge to charge the battery
Ability.
Existing intelligent movable traffic lights either uses ultra-wideband wireless location technology or GPRS to control, and positioning accuracy is all
Centimeter Level cannot be reached, automatic driving vehicle can not be embodied as, the function of GNSS satellite differential data is provided.Currently, driving automatically
It sails vehicle in the process of moving, in order to realize centimeter-level positioning precision, requires the base station GNSS and satellite difference data are provided.This hair
Bright achievable RTK settlement capability provides a variety of differential datas such as RTCM3.2, RTCM3.0 and CMR for automatic driving vehicle.
It designs through the invention, can concentrate and collect all intelligent traffic light exact positions, provide effective spy for SLAM technology
Levy point, operation in the test of auxiliary automatic driving vehicle, road test or Demonstration Area.
In addition, mobile base station is all using tripod at present, it is not very stable；Mobile traffic lamp is stablized, and has built-in
Stable dc power supply can provide effective power supply for the base station GNSS and position is fixed.
The present invention is more specifically illustrated with reference to the accompanying drawing:
The intelligent mobile traffic lights of the base station GNSS differential data can be provided as shown, a kind of, including GNSS board 106, integrated
Control unit 101, radio station module 105,4G network module 104, traffic lights display control unit 201 and solar panel 303.
GNSS antenna 406 receives the signal from satellite, calculates current UTC time by GNSS board 106, longitude and latitude position and searches
Starlike state, by these information, even simultaneously differential data is sent to integrated control unit 101.Integrated control unit 101 controls radio station mould
Differential data is sent out by block 105 and 4G network module 104 by radio antenna 405 and 4G network antenna 404.Radio station module
105 be a kind of data transfer mode of broadcast type, satellite difference data overseas broadcast formula can be sent, and is set as long as receiving radio station
Frequency of radio station is set, aerial baud rate is consistent with data protocol, so that it may receive satellite difference data.4G network module 104 can
To make the mode of encryption satellite difference data.Not over connection particular server, it is unable to get satellite difference data.4G
Network module 104 needs to be packed into SIM card, and consumption data flow needs to buy flow at operator, and it also requires purchase net
The support of network server, but its follow-up maintenance needs expense to support.Two ways can externally send satellite difference data,
One way in which can be selected as the case may be.
Integrated control unit 101 accurately can provide reliability by UTC time for traffic lights display control unit 201
High time standard, traffic lights display control unit 201 control the plan as desired of traffic lights display module 202 using UTC time
Show slightly the state for showing traffic lights current demand.
Due to there is a reference of UTC time, integrated control unit 101 can control solar panel rotating electric machine 305 according to
Current maximal illumination state, makes solar panel 303 receive sunlight with maximum area, passes through battery Charge Management unit
304 are supplied to battery 1 302 and the maximum charging current of battery 2 301.In rainy days, solar charging electrical efficiency
Possibly full electrical storage cell replacement can not can be used at this time by solar recharging in decline, battery 1 302 and battery 2 301,
When one of them is replaced, another can maintain system worked well, also be replaced to another, whole system is again
Full electricity working condition.
Battery Charge Management unit 304 monitors the real-time voltage of battery 1 302 and battery 2 301, and data are passed
Integrated control unit 101 is transported to, low-voltage alarm can be triggered when low battery, prevents traffic lights from leading to operation irregularity due to power shortage
Or the case where closing.
The effect that WiFi module 103 primarily serves is that wireless mode can be used, and is changed by integrated control unit 101
The setting of GNSS board 106 and traffic lights display control unit 201 obtain Current traffic lamp in real time and show state and Current traffic lamp
Position.
Bluetooth module 102 is used as 101 alternate data interface of integrated control unit, and effect can be identical as WiFi module 103,
Play the role of spare upgrading or change.
The present invention combines the base station GNSS with intelligent movable traffic lights, it is advantageous that: intelligent movable traffic lights will lead to
It crosses UTC time control traffic lights and shows that traffic lights show state and state retention time length in default specific time；It can make
Solar panel receives sunlight irradiation with maximum area, to charge the battery；It can be with the current intelligent movable of precise marking
Traffic lights position；A plurality of data link may be selected, and carry out data interaction and parameter configuration.
It takes or uses for reference prior art and can be realized in the part that do not addressed in aforesaid way.
Above only describes the basic principle of this patent and preferred embodiments, it is noted that for the technology of this field
For personnel, under the premise of not departing from this patent structure, several modifications and improvements can also be made, these also should be considered as this
The protection scope of patent.
