Embodiment
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
The preposition caution system of traffic administration signal based on mobile unit includes：RFID active labels and car-mounted terminal.
RFID active labels, are arranged on traffic sign, traffic management information and directional information on record road, each
Label is encoded according to the information on label by coding rule.In the range of vehicle is penetrated into label frequency, car-mounted terminal
RFID card reader can be read out to the active label around road automatically, and the information read is passed through in control channel
Controller is reached, the processing of data is carried out.
Active label (Active) itself have battery can continued power, and effective working distance can reach 100m,
The capacity of storage is and relatively low to signal strength requirement more than 16K bytes.
Because many traffic management informations have directionality, if single only set traffic management information to be possible to cause
Misleading to opposed vehicle, it is therefore desirable to set up directional information at each message board.In configuration information, give tacit consent in traffic pipe
Placement direction information before information is managed, when the directional information that and if only if reads is consistent with direction of traffic, just traffic administration is believed
Breath is made a response, and is not otherwise made a response.
Traffic management information includes：Caution sign, prohibitory sign, speed(-)limit sign and auxiliary information.Caution sign：Such as hand over
The cross road mouthful mark, sharp curve way mark, children crossing indicates, emergency lane mark etc..Prohibitory sign：Such as give way mark
Will, Traffic has priority over oncoming vehicle mark, traffic prohibited sign, no entry sign, no parking mark etc..Speed(-)limit sign：It is at different levels
Road speed limit warning information.Auxiliary information：Such as accident prone location, temporary traffic management and control, temporary construction management, upcoming traffic thing
Therefore development, Weather information early warning etc..
Traffic management information is classified, every traffic management information has independent corresponding RFID active labels,
RFID card reader can independently differentiate traffic management information, mutually be connected with speech prompting system, realize accurate traffic management information
Early warning.Such as：Different labels are set up according to different traffic management informations, are numbered according to traffic management information.Every friendship
Logical management information, which has, exclusively enjoys electronic tag, and RFID reader can independently differentiate its information contained (in which roadbed section), and
Mutually it is connected with speech prompting system, realizes accurate traffic management information early warning.
Car-mounted terminal includes RFID card reader, receiver, controller and speech prompting system.
Receiver is received to the traffic management information and directional information on RFID active labels.Receiver is using wireless
Radio-frequency technique transmits data.When wireless radio-frequency transmits data, using EPCI8000-6B standards, standard Maturation, product are steady
Determine, be widely used；The ID whole world is only；No. ID is first read, data field is read afterwards；1024bits or 2048bits Large Copacity；
98Bytes or 216Bytes large user data field；Multi-tag is read simultaneously, and dozens of label can be at most read simultaneously；Data
Reading speed is 40kbps.
RFID card reader reads the traffic management information received and directional information is received.RFID card reader includes inspection
Slowdown monitoring circuit, signal modulation, radio frequency module for reading and writing circuit, micro control unit circuit and serial communication circuit.Card reader uses frequency range
For 5800~6800MHz, this frequency range is non-control frequency range, and wherein 5.8G is in Countries positioning intelligent transportation system frequency
Section.
When controller judges that the directional information of reading is consistent with direction of traffic, speech prompting system reports traffic administration letter
Breath；Otherwise, speech prompting system does not report traffic management information.
Distinguished to distinguish over other RFID active labels for being possible to occur on road in goods vehicle, in the present invention
Using independent label coding rule.Wherein label is divided into direction label and management information label, and two kinds of labels are using different
Coded system.
Directional information RFID tag coding rule：
JT XX XX XXXXX
The specific object information sequence number of traffic category directional information management information sorting sequence number
Traffic management information RFID tag coding rule：
JT XX XXXXX
The specific object information sequence number of traffic category management information sorting sequence number
Wherein, management information value is 01 --- caution sign, 02 --- prohibitory sign, 03 --- speed(-)limit sign,
04 --- auxiliary information；Specific object information is encoded in each category information, it is specific right in each of which category information
Image information can cover 10000；Directional information is 01 --- it is positive, 00 --- and it is reverse.Directional information is a definite value, is used for
The directionality detection of label information.
Directional information is changed to serial number information, such as first reads No. 1000, and No. 1001 are only read again, by this order ability
Activate the traffic management information of response.
The system communication frame format of table 1.
In car-mounted terminal, the information of active label on Subgrade can be read automatically, and transmit it to controller, in control
Handled on device processed.Controller has corresponding voice for each code storage, the active label coding that card reader is read
Handled by control channel transmission into controller, when result by after just carried out by vehicle-mounted multimedia equipment it is defeated
Go out.For example, after the active label for receiving JT010100001 and JT0100001 is encoded, host computer judged result is, direction
There is caution sign in front to information --- traffic management information ---：Zig zag, then calls the audio output voice message of storage
Warning：" there is zig zag in front, and Please drive carefully.”
As shown in Fig. 2 setting up in RFID active labels, directive traffic management information is on setting up using double
Tagged manner determines direction.Such as forbidden mark.
When the information order that card reader is read is direction, command information, the order is just performed；On the contrary, when vehicle is read
When getting instruction, directional information, then the order is not performed.In addition, when pipe in direction label and traffic management information label
Manage information sequence number it is different from specific object information sequence number when, also do not make a response, both and if only if it is identical when and it is suitable
When sequence arranges correct, computer can just make command adapted thereto.
In order to ensure the reading problem being likely to result in during tag damage, RFID active labels also include leading information, in control
Increase clock system in device processed, leading information then resets order when not reading the certain intervals time.
As shown in figure 5, RFID card reader reading electronic labels data, controller judges whether it is leading information.
When being judged as non-leading information, then determine whether effective traffic management information.It is judged as effective traffic administration letter
During breath, corresponding voice message is activated.When being judged as invalid traffic management information, do not do and react.
When judging non-leading information, leading information is prestored, and activates timer.Whether information kisses before and after judging
Close, i.e., whether leading information is consistent with traffic management information.When front and rear information is coincide, then judge leading information and traffic administration letter
Read access time, the i.e. time of timer accumulation are ceased whether within the time of restriction.It is effective information in limiting time, activates phase
The voice message answered；It is invalid information not in limiting time, does not do and react.
When front and rear information misfits, it is determined as invalid information, does not do and react.
