Fig. 2 is the process flow diagram of second accident method for early warning of the present utility model.
In figure: 1 vehicle location card, 2 second accident monitoring base stations, 3 preposition warning screens, 4 management information platforms.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, give the schematic diagram of second accident early warning system of the present utility model, it is made up of vehicle location card 1, multiple second accident monitoring base station 2, preposition warning screen 3, management information platform 4; Vehicle location card 1 is made up of active rfid module, power supply, power management module and status indicator lamp, for there is radiofrequency signal in active rfid module, power supply is used for providing power supply, power management module realizes the management to power supply, and status indicator lamp is for showing the duty of vehicle location card 1.Vehicle location card 1 can adopt the form being packaged in highway IC and passing through in cutting ferrule, provides, regain at expressway exit place with IC visa card in expressway access with IC visa card.Broadcasting unique ID with the time interval (a transmission cycle only adds base station once, is 3 seconds as set interval) of presetting during the work of low-power consumption active RFID module to indicate, after being sent, entering low power consumpting state immediately.
Shown multiple second accident monitoring base station 2 compartment of terrains are arranged in the central partition in accident section occurred frequently of highway, and second accident monitoring base station 2 is made up of RFID radio frequency reader, camera, GPRS communication module, point-to-point telecommunication module and power module.RFID radio frequency reader is in the state of intercepting all the time, to receive the rf data of vehicle location card 1 transmission; Second accident monitoring base station 2 is by camera collection pavement image, communicated with management information platform 4 by GPRS communication module, to be uploaded to by the pavement image of collection in management information platform 4, GPRS communication module includes antenna, and described antenna height should on distance more than 1.5 meters, ground.Second accident monitoring base station 2 realizes transmit with the data of preposition warning screen 3 by point-to-point telecommunication module, so as detect road has accident to occur or be in extreme block up time, preposition warning screen 3 sends early warning information.
Shown preposition warning screen 3 is arranged at the front end in accident section occurred frequently, it is made up of LED display, microprocessor, power module and point-to-point telecommunication module, LED display is for showing information warning, microprocessor has data processing and controls the effect of output, and preposition warning screen 3 realizes transmitting with the data of second accident monitoring base station 2 by point-to-point telecommunication module.Position is there is according to the base station numbering judgement accident sending alarm in preposition warning screen 3 after receiving exceptional instructions, and display alarm deceleration information.
Shown management information platform 4 is arranged at Surveillance center, it is made up of PC and GPRS communication module, management information platform 4 realizes transmitting with the data of second accident monitoring base station 2 by GPRS communication module, to receive the image that second accident monitoring base station 2 is uploaded, check for managerial personnel.Managerial personnel can pass through described management information platform real-time reception congestion information, according to picture analyzing judgement accident rank, as being wrong report, then cancel LED alarm; The accident that truly has then makes counter-measure as the case may be.
In the process of work, after within the communication range that the vehicle carrying vehicle locator card 1 enters second accident monitoring base station 2, the packet indicated containing self unique ID is broadcasted with fixed cycle T, second accident monitoring base station 2 judges whether the interior number of data packets containing a certain ID sign received of the time period t set reaches upper threshold, if reach upper threshold, then show that the vehicle in this section is in state that is static or that extremely block up, this section, surface may have occurred traffic hazard, then send information to carry out the display of information warning to preposition warning screen, driver is caused to note, avoid the generation of second accident., the pavement image of camera acquisition is uploaded in management information platform 4, so that managerial personnel carry out confirming or taking counter-measure meanwhile.
As shown in Figure 2, give the process flow diagram of second accident method for early warning of the present utility model, it is realized by following steps:
A). send data, vehicle location cartoon is crossed active rfid module and is launched the packet comprising self unique ID and indicate with fixed cycle T towards periphery;
B). receive data, second accident monitoring base station remains at the state of intercepting, and carries out Automatic analysis when receiving wireless data packet, if wireless data packet is the data that vehicle location card sends, then performs step c);
C). judge that, without there being record, second accident monitoring base station extracts vehicle ID beacon information from the wireless data packet received, and whether receive the wireless data packet indicated containing this ID before judging, be if received before, then performed steps d); If between do not have reception to be, then perform step e);
D). receive number of times and add up, this ID is indicated the number of times m received and carry out "+1 " operation; Perform step f);
E). receive number of times and put 1, this ID is indicated the number of times m received and carries out putting 1 operation; Perform step f);
F). judge whether to reach setting-up time section, judge that ID to indicate from the moment that first time is received till now, whether reach the time period t of setting, if reached, then perform step g); If do not reached, then perform step b);
G). judge whether receive number of times transfinites, judge that the ID received in the time period t of setting indicates number of times and whether exceedes setting threshold value, if exceed setting threshold value, then perform step h); If do not exceed setting threshold value, then perform step I);
H). send information warning and upload images, if a certain ID is indicated in the number of times received in the time period of setting exceeded setting threshold value, then show that this vehicle is in static or extreme congestion status in this section, may there occurs traffic hazard, then to be given a warning information by preposition warning screen, to avoid the generation of second accident; Gather image simultaneously and be sent to management information platform, carry out confirming and taking corresponding measure for monitor staff;
I). remove record, if a certain ID is indicated in the number of times received in the time period of setting do not exceeded setting threshold value, then show that the vehicle speed carrying this vehicle location card is normal, this section is in unimpeded state, occur without traffic hazard and jam, this ID is indicated the number of times received and carries out clear operation.
