Embodiment
For ease of technical solution of the present invention being had better, understand, first the application scenarios of the present embodiment vehicle running state method for supervising is described below.
Fig. 1 is the scene schematic diagram that in the embodiment of the present invention, trackside beacon detects vehicle running state.As shown in Figure 1, the section A1 in traffic route, section A2 are respectively arranged with trackside beacon B1 and trackside beacon B2, and wherein, the signal of trackside beacon B1 transmitting can the whole section A1 of sighting distance wireless coverage, can carry out radio communication with the vehicle travelling in the A1 of section; The signal of trackside beacon B2 transmitting can sighting distance cover whole section A2, can carry out radio communication with the vehicle C that travels in the A2 of section, and trackside beacon all has the geographical location information in location, place.In road shown in Fig. 1, A1He section, section A2 is right-angled intersection; Trackside beacon B1 and trackside beacon B2 can communicate the vehicle travelling in section separately, to monitor in real time the transport condition of car two, each trackside beacon can be monitored entering the vehicle in own section, the section that wherein trackside beacon institute sighting distance covers, be the section of predeterminable its management in the geography information in location, trackside beacon place, and the vehicle in section is monitored in real time.
In the present embodiment, the section that trackside beacon can its place of sighting distance wireless coverage, forms the banded communication cell covering, and stores the geographical location information in this section, thereby can monitor in real time the vehicle travelling in its section, place; On the car-mounted terminal of vehicle, be provided with intelligent plane antenna, can be in real time and trackside beacon communicate.Wherein, described sighting distance wireless coverage section refers to that trackside beacon can carry out horizon communication with the vehicle that travels on section, does not have the isolation such as other buildingss between vehicle and trackside beacon.
Below in conjunction with instantiation, technical solution of the present invention is described further.
The structural representation of the car-mounted terminal that Fig. 2 provides for the embodiment of the present invention one.The present embodiment car-mounted terminal is arranged on and travels in the vehicle of scene as shown in Figure 1, on this car-mounted terminal, be provided with intelligent plane aerial array, the trackside beacon of road side setting can be communicated by letter with car-mounted terminal in real time, obtain the transport condition of vehicle, particularly, as shown in Figure 2, the present embodiment car-mounted terminal can comprise:
Direction acquiring unit 11, for the beam direction of the pilot signal of trackside beacon transmission being detected by intelligent plane aerial array, the headstock that obtains vehicle points to;
Geographical locationinformation transmitting element 13, is sent to trackside beacon by the positional information of vehicle for real-time or cycle, and the positional information of this vehicle comprises that the distance of the relative trackside beacon of vehicle and the headstock of vehicle point to.
On the present embodiment car-mounted terminal, be provided with intelligent plane aerial array, Vehicle Driving Cycle is on road like this, during section A1 as shown in Figure 1 of example, just can receive the pilot signal that B1 sends, direction acquiring unit 11 in car-mounted terminal just can detect the beam direction of pilot signal by detecting intelligent plane aerial array, obtain the angle of the relative trackside beacon of vehicle, and then the headstock of definite vehicle points to.Particularly, in the present embodiment, intelligent plane aerial array adopts planar array antenna, the section that trackside beacon can cover to its sighting distance in real time, it is section, trackside beacon place pilot signal transmitted, the phase place of pilot signal that vehicle just can pass through each antenna element reception in the planar array antenna on it is like this, the difference of energy, form beam pattern, calculate the angle of the relative trackside beacon of vehicle downgoing signal radiation direction, obtain the direction of the relative trackside beacon of intelligent plane aerial array, and then the headstock of definite vehicle points to.It will be appreciated by those skilled in the art that, because the direction of the relative vehicle headstock of intelligent plane aerial array of installing on car-mounted terminal is known, as long as obtain the direction of the relative trackside beacon of intelligent plane aerial array, just can determine the direction of the headstock of vehicle, i.e. the sensing of headstock.
In the present embodiment, trackside beacon can real-time broadcast self Navsat longitude and latitude locating information, like this,distance acquiring unit 12 on car-mounted terminal just can be according to the Navsat longitude and latitude locating information of the trackside beacon receiving, and the Navsat longitude and latitude locating information of self, determine the distance of the relative trackside beacon of vehicle.It will be appreciated by those skilled in the art that, the Navsat longitude and latitude locating information of trackside beacon is specifically as follows GPS locating information, can be obtained by the GPS receiver being arranged on trackside beacon, the Navsat longitude and latitude locating information of vehicle termination can be obtained by the GPS receiver being arranged on car-mounted terminal, wherein Navsat longitude and latitude locating information latitude and longitude information specifically.
In the present embodiment, car-mounted terminal on vehicle is according to the Navsat longitude and latitude locating information of the trackside beacon receiving in real time, and the locating information of self just can obtain the distance of its relative trackside beacon, thereby can directly this range information be sent to trackside beacon, make to send to the quantity of information of trackside beacon will be very little, be convenient to trackside beacon and receive and process vehicle transmission information, be convenient to the real-time monitoring of trackside beacon to a large amount of vehicles on section, improve accuracy and the reliability of monitoring.
In the present embodiment, as shown in Figure 2, this car-mounted terminal also can comprise:safe antitheft module 14 andantitheft notification module 15, wherein,safe antitheft module 14 is during for vehicle parking, close the communications transmit module of car-mounted terminal, and by the communications reception module of car-mounted terminal, the signal receiving by intelligent plane aerial array is detected, the varying strength of determining pilot signal that trackside beacon the sends different directions in each antenna array unit changes, determine the environmental change of vehicle periphery, to judge whether safety of vehicle;Antitheft notification module 15 is when judging that vehicle is dangerous, and the communications transmit module of opening vehicle mounted terminal, sends vehicle unsafe conditions change notification to trackside beacon, until after wireless receiving signal stabilization, and communication close transmitter module again.Because trackside beacon is in real time to its section, place broadcast pilot, during vehicle parking, when having theft personnel to steal vehicle, vehicle-periphery will change, the pilot signal that trackside beacon is sent exerts an influence, therefore, and by setting and detect the intensity of variation of pilot signal energy in all directions that intelligent plane aerial array receives, just can change by perception vehicle-surroundings environment, determine whether safety of vehicle.In the present embodiment, car-mounted terminal is when carrying out radio communication with trackside beacon, can be undertaken by the communications transmit module on it and communications reception module, when vehicle parking, can communication close transmitter module, only need open communication receiver module to determine that whether vehicle is stolen by detecting the signal of trackside beacon transmission, thereby can save the power consumption of car-mounted terminal, wherein, communications transmit module and communications reception module are communicated by letter by smart antenna with tradition transmits and receives module and can have identical 26S Proteasome Structure and Function, and concrete structure does not repeat them here.
