Market demand
As one of the main passenger transportation methods, long-distance buses occupy a broad market space in the passenger transportation field due to their extensive road network tentacles and relatively frequent trips. However, the weakness of poor safety is also an indisputable fact in the field of passenger transportation. In particular, human factors such as halfway soliciting and driver fatigue make long-distance buses give passengers a much lower sense of safety than airplanes and trains. In view of this,HelicommexistZigBeeOn the basis of technology, combined with the driving recorder, a long-distance bus driving record collection system was developed to effectively collect the full-distance driving status of the long-distance bus. By collecting the number of parking times, the number of braking times, the driving time and other parameters, it can effectively predict whether the car has halfway soliciting, accidents, etc. The occurrence of fatigue driving and other events effectively reduces the probability of man-made accidents and greatly improves the safety of long-distance bus journeys.
solution
As shown in the picture, first useIP-Link2220PSet upZigBeewirelessmeshNetwork, especially one at the entrance and exitReader, So that drivers can upload driving data as soon as they enter the passenger terminal.Install inlays inside the car separatelyZigBeeThe module’s driving recorder, in the usual car driving, the driving recorder will record the vehicle driving status, mileage, accident suspects, fatigue driving and other information records and store it in the memory card of the driving recorder.When the car arrives at the destination station, the driver presses the active upload data button on the dash cam, and the data in the dash cam memory card will pass through the parking lot.ZigBeewirelessmeshUpload data from the network to the central server. The central server can analyze according to the uploaded data, and finally obtain the whole state of the car during the journey, and store statistics.
