See also Fig. 8, when the intelligent electronic prealarming system that is equipped with the utility model to be used for the electronics warning board subsystem of intelligent electronic prealarming system is applied to express highway section, specific as follows described:
When certain that begins to enter highway as the vehicle CarX72 that prewarning unit is housed is led the way, can see an electronic caution board DLx401 at this crossing of leading the way, whether the driver enters highway according to the content decision of DLx401 prompting.If driver's decision also enters highway, in the side of leading the way early warning control subsystem CS501 is housed, CS501 notes the number-plate number and the photo of this vehicle; Between CS501 and electronic caution board Dli-1402, the driver can understand vehicle ' the place ahead by the content of Dli-1402 prompting, Dli403, the Dli+1404 after the electronic caution board Dli-1402 even the traffic pavement behavior of farther place express highway section.
When vehicle CarX72 process electronic caution board Dli-1402, the prewarning unit 20 of this car establishes a connection with this electronic caution board Dli-1402 by transceiver module 28, electronic caution board Dli-1402 obtains the code name and the position coordinates of vehicle at any time, and the prewarning unit 20 of CarX72 establishes a connection by the prewarning unit of Dli-1402 and vehicle CarA78, vehicle CarB79.Simultaneously, 44 inductions of Dli-1402 ultrasonic sensor have vehicle to pass through, and counter adds 1, and this subsystem software provides different informations with the vehicle flowrate situation according to the intensity of luminous ray in light language and characters image caution 45; And visibility sensor 42 also periodically detects the intensity of luminous ray and passes to CPU41, switch by CPU41 control range light 46, when inclement weather visibility such as night, sleet mist are low, the unlatching of range light 46, follow-up vehicle CarC77 advanced plays a part navigation.
Electronic caution board Dli-1402 judges the transport condition of CarX72 by calculating the speed of vehicle CarX72; When hypervelocity, low speed or dead ship condition appear in CarX72, it is warned by speech line; If long-time violating the regulations, then the violation information of this vehicle is passed through network, be delivered to alarm center 60, store in the network database system 62 by alarm center CPU61, as the foundation of punishing in the future.And when distance between CarX72 and CarA78 to a certain degree, the prewarning unit of CarX72 and CarA78 is according to the trend of two car convergences, also can point out the driver to note knocking into the back or after hit.
When collision or overturn accident took place vehicle CarX72, the mercury bead e of velocity variations sensor 22 slided rapidly, and the CPU21 of prewarning unit 20 judges the collision signal automatically, and the light and the phonetic alarm 27,26 that drive this vehicle are immediately reported to the police; And, be transmitted to the vehicle of Dli-1401 and follow-up hundreds of rice distance with collision signal process transceiver module 28, receive that nearby the vehicle CarA78 of information gives driver's voice suggestion of this car and light prompt; And some electronic caution boards such as the electronic caution board Dli-1402 of back and DLx401, provide corresponding prompt, CarC77 and CarX72 at a distance knows that by electronic caution board accident appears in the front, thereby can realize closely warning function and prompt facility fast at a distance, and the electronic caution board Dli403 in the place ahead, vehicle CarD791 transceiver module receive information, but it is after send at the rear that software is judged, refusal is further handled.
When occur blowing out, vehicle fault such as engine kill, perhaps run into when robbing car, the driver can press correspondent button K1, the K2 of prewarning unit 20, by CPU21 and transceiver module 28, send signal to electronic caution board, by electronic caution board help signal is passed to alarm center 60 again, the emergency vehicle is helped by alarm center 60 tissues.If fault is got rid of, dangerous situation is removed, and the driver can press reset key K3 and recover prewarning unit 20 normal work functions.
When vehicle CarX72 advances through electronic caution board Dli403, electronic caution board Dli-1402 removes the annexation to this car, and the prewarning unit 20 of this car is promptly set up new annexation with this electronic caution board Dli403, and Dli403 is identical to the effect of this car with previous Dli-1401.
Be appreciated that, electronics warning board subsystem of the present utility model and above-mentioned prewarning unit, early warning control subsystem and alarm center adopt the high data rate radio receiving transmitting module, and between each early warning control subsystem, the early warning control subsystem can adopt wireless with alarm center or cable network is connected, carry out both-way communication between each equipment, guarantee transmitting effectively fast of signal; Signal between the detection of each device interior signal, processing, control and the distinct device receives to send and independently carries out, and realizes filtration and screening to signal on software, reduces and avoid the reception and the transmission of noise or garbage signal.
Be appreciated that, above-mentionedly just set forth a typical embodiment of the present utility model, under the prerequisite of essence of the present utility model and spirit, for arriving all or part of function of the present utility model, embodiment that the utility model is concrete and content can be different.
