Embodiment
Below in conjunction with accompanying drawing, utilize embodiment that the utility model is described further.
As depicted in figs. 1 and 2; The described information of vehicles based on the ZigBee technology of the utility model reaches prior-warning device alternately, replys shortcut 4, system reset device 5, console touch-screen 6, memory 7, ZigBee communication module 8, headstock directional transmissions and reception antenna 9 and tailstock directional transmissions and reception antenna 10 by embedded type control module 1, clock module 2, vehicle-mounted electric power system 3, multifunctional direction dish and forms.Wherein, embedded type control module 1 and ZigBee communication module 8 are connected through spi bus; Clock module 2, vehicle-mounted electric power system 3, system reset device 5, memory 7 are connected with embedded type control module 1 respectively, form embedded control system; Shortcut 4 replied by the multifunctional direction dish and console touch-screen 6 directly is connected on the embedded type control module 1 through the I/O bus, just can other vehicles be expressed or are sent in data that obtain and the instruction that will send accurately through the processing of embedded control system; Headstock directional transmissions and reception antenna 9 are connected with ZigBee communication module 8 with tailstock directional transmissions and reception antenna 10, form wireless communication module, realize the wireless receiving and dispatching of data.
S3C2440 type central processing unit as shown in Figure 6, that the CPU of embedded type control module 1 adopts Samsung to produce; Wireless communication module adopts the CC2430 radio frequency chip of American TI Company to accomplish the transmission and the reception of data in the ZigBee network; CC2430 utilizes its SO, SI, and SSn, SCLK connect the corresponding SPI communication interface of S3C2440.Like Fig. 6 and shown in Figure 7, it is the HY57V561620 type SDRAM of 32MB that memory 7 adopts two block sizes.
The license number of motor vehicle writes in the ZigBee radio frequency chip in advance; Make the corresponding unique ZigBee chip of unique license number; When guaranteeing to communicate between vehicle, not only comprising unique number-plate number information that the ZigBee hardware identifier is also comprising vehicle in the packet of transmission.After node receives packet and finally be embedded into the formula system unpack the contrast destination address whether conform to itself, if meet then the retention data bag, otherwise be dropped.Through with the road surface on other vehicles set up communicate by letter and obtain some ZigBee and number, make license plate number and ZigBee chip number sit in the right seat.After these information unpacked through embedded control system, license board information just can be fed back on the console touch-screen 6 of vehicle (as shown in Figure 4) accurately, and what on the console touch-screen, shown is the embedded number-plate number of corresponding unique ZigBee numbering.So just the ZigBee numbering is connected with real license plate number one by one, the driver just can keep communicating by letter with a certain vehicle selectively, and does not influence other vehicles.When on the way going, the interim WPAN system that forms through ZigBee between the vehicle of not knowing each other mutually communicates.
As shown in Figure 3, present embodiment is the sketch map that vehicle utilizes the communication of the utility model device promptly will get into solid region at the parting of the ways the time.When the signal lamp of left-hand rotation Through Lane for turning left to forbid, when only allowing to keep straight on, forget because the front truck desire is turned left and to play the left steering lamp; Then the car intention is kept straight on, and does not obtain the clear and definite signal of front truck travel route again, does not know that front truck is kept straight on or left-hand rotation; Whether can follow without lane change; Worry to get into solid region lane change in time to the right again, at this moment, utilize the utility model device; The driver of back car sets up autotelic communication through the definite ZigBee identity of car plate identification; Send travel route inquiry message (being information A among Fig. 3) to front truck earlier, then obtain the clear and definite answer of front truck: the feedback information that will turn left (being information B among Fig. 3), so car lane change in time before getting into solid region in back is kept straight on (being C among Fig. 3); Thereby avoid under the left-hand rotation Through Lane turns left situation about forbidding, desire is kept straight on follows that vehicle is waited for by the front that the vehicle that turns left stops and the phenomenon of losing time takes place.
The multifunctional direction dish that running information between vehicle is settled through the both sides of steering wheel for vehicle is alternately replied shortcut 4 and is sent.This group shortcut is provided with inquiry commonly used, answers order, can carry out simple and the most frequently used question and answer (as shown in Figure 5) quickly and easily, and wherein, 1. shortcut can be made as " inquiry travel direction "; 2. shortcut is made as " overtake other vehicles and please note "; 3. shortcut is made as " please announce road conditions "; 4. shortcut is made as " turning left to note "; 5. shortcut is made as " turn right and note "; 6. shortcut is made as " craspedodrome "; 7. shortcut is made as " the place ahead accident, brake please notes "; 8. shortcut is made as " attention spacing ".
As shown in Figure 4, the console touch-screen 6 that is installed under the steering wheel can be used to select communication pattern and set up the autotelic demonstration of running information between vehicle afterwards of communicating by letter.When selecting ad hoc mode through the console operation knob; After obtaining the corresponding license plate number in unique ZigBee address; Can carry out the communication between the vehicle, information of vehicles manifests on display screen, and the driver is after observing the license plate number of front truck; On display screen, clicking mark with hand has the vehicle of front truck number to carry out man-to-man communication, through the mutual both sides' of menu option running information.When the condition of road surface circular of selecting the message pick-up pattern through the console operation knob, can receive to send by traffic information center.
