Research On Wireless Voice Parking Guidance System Based On The Optimal Path

With the development of the country’s automobile industry and people’s livingstandards,car ownership is rising rapidly.Parking contradiction between supply anddemand is growing increasingly.And the problem of parking becomes prominent.Degreeof intelligence and level of management in domestic car parking guidance system needto be improved. Some parking lots are low efficiency with high cost of artificial guide.Some parking guidances realize by LED screen.But this way has some disadvantages. Itis not enough visible, limited viewing distance, induced screen wiring range andprovided.amount of a single limited information Induced by the presence of the carparking, parking guidance system based on the optimal path of wireless voice, isproposed.The domestic and foreign technology application status of car parking guidancesystem had been studied in the paper firstly.The demand for the car parking guidancesystem. was analyzed.On this basis, the overall structure and parking process of theprogram for wireless voice parking guidance system had been designed.The paper made in-depth research on several mainstream vehicle detectionmethod.The vehicle detection system of entrances and exits based on United StatesBonner MINI-ARRAY two measuring lights curtain sensors had been designed. WithC8051F020microcontroller,the lane vehicle tracking and parking space detectionsystem based on magnetoresistive sensor of Honeywell were studied.Then,it discussedthe installation of the magnetoresistive sensor.The paper made comparison to theadvantages and disadvantages of the parking vehicle information by wired and wirelesstransmission scheme. A vehicle information transmission system based on RS-485buswas designed.Parking lane path choice largely affected the efficiency of parking guidance.Thepaper made comparative analysis of many route guidance algorithms. Section of busycoefficient was introduced to improve ant colony algorithm,making use of improved antcolony algorithm to search for optimal driving paths.Parking spaces structure model hadbeen established.It described the concept of optimum path in this article.The optimaltravel path of the parking spaces by improved algorithm simulation results wereanalysed.The paper analysed the functional requirements and hardware resources of wireless voice parking guidance broadcast system, including the selection of microcontroller,vehicle RF card and wireless transmission module.Details Voice recording, play thefeasibility of the principles and software development environment of SPCE061AMicrocontroller. were introduced in detail. Compared with two ways of wireless voicebroadcast, the paper proposed a wireless the parallel voice broadcast system.At last, thecommunicate distance test of parking induction of wireless voice broadcast system hadbeen made.The test results showed that the program could be used in the voice parkingguidance.Parking guidance management system of wireless voice had been developed basedon Visual Basic6.0development platform and SQL Server2000database. The parkingmanagement database were designed in the paper.Several ways access to database byVB were compared carefully.Finally, the main function module such as interface oflogin module management system, user management module, vehicle RF cardmanagement, charge management and vehicle-induced management were implemented.
