Background technology
Along with automobile is day by day universal, when having changed people's production, life and the mode of thinking, also bearing the misery that traffic hazard brings to people.And in whole road traffic accident, rear-end collision accident accounts for more than 70%, the pernicious traffic hazard of the dead group's wound of some large groups, starts also may just by slight together rear-end collision, be caused most.According to statistics, in vehicle driving risk situation, if can shift to an earlier date the reaction time of 0.5s to driver, can reduce respectively 30% of collision tail accident, 60% of the car accident that heads on, 50% of the relevant accident in road surface.Therefore, how at place where the accident occurred point, to remind in time other drivers to take safety measures, seem most important.And in this respect, existing technology is difficult to accomplish in time, accurately, at a distance driver is following closely accomplished to security reminds.As mono-kind of < < solves the method > > (application number: 02142356.3) its technical scheme is when vehicle sails expressway into of highway continuous rear collision accident, be equipped with an electromagnetic transceiver, stop for some reason or rear-end collision has occurred, initiatively trigger electromagnetic wave dispensing device, for all vehicles in its range of signal receive, continuous rear collision while avoiding accident to occur.Prior art shortcoming is that electromagnetic transceiver, easily receives external information and disturb.Frequency resource is limited, delimit a frequency range waste very much to R-T unit.Sail into, End of motorway mouth, to equipment assembling with regain, especially loaded down with trivial details, time-consuming, certainly will affect high speed crossing traffic efficiency.
Utility model content
Technical problem to be solved in the utility model, with regard to being to provide a kind of vehicle on highway based on Internet of Things early warning system that knocks into the back, utilizes Internet of Things and vehicle-carrying communication network that vehicle collision prewarning is provided.
The utility model solve the technical problem, the technical scheme adopting is, vehicle on highway based on the Internet of Things early warning system that knocks into the back, comprise the car-mounted terminal for the treatment of data, crash sensor for detection of vehicle collision, OBD detection module for detection of vehicle trouble, GPS module for vehicle location, it is characterized in that, also comprise for the ZigBee module of inter-vehicular communication with for the Internet of Things communication module of network service, described crash sensor is connected with car-mounted terminal, to car-mounted terminal transmission collision alarm, described OBD detection module is connected with car-mounted terminal, to car-mounted terminal transmission vehicle scram signal, described GPS module is connected with car-mounted terminal, to car-mounted terminal transmission vehicle location signal, described car-mounted terminal is connected with ZigBee module, by described ZigBee module and other vehicles, carry out radio communication, described car-mounted terminal is connected and carries out network service with Internet of Things communication module.
Preferably, described ZigBee module is operated in 2.4GHz frequency range.
Concrete, described ZigBee module adopts the CC2480 network processor chip of Texas Instruments to form.
Concrete, described Internet of Things communication module adopts the CC2480 network processor chip of Texas Instruments to form.
The beneficial effects of the utility model are that employing ZigBee module is carried out short-range communication, in time the vehicle in ZigBee-network coverage is carried out to early warning; Utilize Internet of Things communication module to connect and carry out network service, to distant vehicle, send early warning in time.The utlity model has communication technology maturation, easy to use, cost is low, early warning range extensively, feature timely.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, describe the technical solution of the utility model in detail.
ZigBee is the radio network technique of a kind of emerging short distance, low-power consumption, low data rate, low cost, low complex degree, has power saving, simple, cost low feature again, and has increased logical network, network security and application layer.The transmission bandwidth of ZigBee wireless network, in 20～25OkB/s scope, is applicable to the transmission of sensor data acquisition and control data very much.Internet of Things is the important component part of generation information technology.Its English name is " The Internet of things ".Thus, as its name suggests, " Internet of Things is exactly the connected internet of thing thing ".This has the two-layer meaning: the first, and core and the basis of Internet of Things remain internet, are extension on Internet basic and the network of expansion; The second, its user side extends and has expanded between any article (comprising vehicle) and article, carries out message exchange and communicates by letter.Internet of Things is exactly " internet that thing thing is connected ".Internet of Things, by the fusion application of Intellisense, recognition technology and general fit calculation, Ubiquitous Network, is called as the third wave of world's information industry development after computing machine, internet.The vehicle on highway of the utility model based on the Internet of Things early warning system that knocks into the back, ZigBee technology and the technology of Internet of things application in vehicle rear-end collision early warning just.
The vehicle on highway of the utility model based on the Internet of Things early warning system that knocks into the back, structure as shown in Figure 1, comprise car-mounted terminal 10 for the treatment of data, for detection of the crash sensor 11 of vehicle collision, for detection of the OBD(On-Board Diagnostics mounted automatic diagnosis of vehicle trouble) detection module 12, for the GPS(GPS of vehicle location) module 13, for the ZigBee module 14 of inter-vehicular communication with for the Internet of Things communication module 15 of network service.Crash sensor 11 is connected with car-mounted terminal 10, and when collision happens being detected, to car-mounted terminal 10 transmission collision alarms, car-mounted terminal 10 receives the information of collision alarm and the transmission of GPS module, determines place and time that collision occurs.Trigger immediately ZigBee module sends early warning signal to the vehicle in its signal cover to car-mounted terminal 10 on the one hand, and prompting vehicle deceleration stops or dodges.By Internet of Things communication module 15, carry out network service on the other hand, to the vehicle outside ZigBee-network coverage, send early warning signal, prompting vehicle is noted dodging or detouring.In the utility model, Internet of Things communication module 15 can be passed through GPRS(wireless, packet-switched technology, provide end to end, the wireless IP of wide area connects) or WIFI(WiMAX) access Internet of Things, by Internet of Things server, send early warning signal, early warning signal receiving end can be the car-mounted terminal of other vehicles, can be also intelligent mobile phone terminal etc.When same OBD detection module detects vehicle trouble and stops in emergency, also stop sign can be sent to the car-mounted terminal 10 of connection, to car-mounted terminal 10 transmission vehicle scram signals, in this case, car-mounted terminal 1 also can send early warning signal by ZigBee module 14 and Internet of Things communication module 15.
In the utility model, the working frequency range of ZigBee module is set in 2.4GHz.This is open common frequency band, has cost low, the feature of technology maturation, the CC2480 network processor chip that the conventional chip model of this frequency range ZigBee module is Texas Instruments.CC2480 network processor chip equally can be for construct connected network communication module.
