Abstract
The invention discloses an intelligent parking lot parking space management and guiding system based on the ZigBee technology. The system is mainly composed of a parking space information detection module, a ZigBee wireless communication module, a parking space guiding module, an information processing module (comprising a region controller and a central control unit) and an image data display module. The region controller is responsible for the parking space information management of a designated region and used to send the statistics information of the region to the central control unit on a real-time basis for processing. Modules, such as a parking space information acquisition module, an information issuing module, a guiding and display module, etc., are all controlled by the central control unit. The central control unit is used to calculate the current best parking space through the shortest path algorithm, and distribute the current best parking space to the current user through a ZigBee wireless network, and at the same time, a guiding display board in the parking lot started to guide the user to the best parking space. According to the system, a car owner can fast find the best parking space, so the operating and management efficiency of the parking lot can be improved.
Description
Technical field
The technical field of patent of the present invention comprises: ultrasonic sensor technology, parking space information detection technique, ZigBee wireless communication technology, parking stall bootstrap technique, parking space information treatment technology, data and image display technology etc.
Background technology
The ubiquitous problem in parking lot has at present:
(1) most of parking lot belongs to labor management, just pay close attention to the situation of gateway, in, also have on earth how many parking stalls to use, supvr knows nothing, can only be by manually going prospecting, cause like this part parking stall Nobody Knows and " unfrequented in front of the door ", and crowded cannot the stopping of subregion vehicle.
(2) person of parking enters and cannot enter rapidly parking spot behind parking lot and park cars, the vacant parking stall of unordered mobile searching inside, and the A-road resource of coming in and going out in not only taking, even can cause site inside accesses to block up.
(3) must be equipped with a large amount of full-time executives artificial guided vehicle in parking lot and park, increase parking lot management cost.
(4) supvr cannot add up the vehicle flowrate of different times every day in time, can not optimize in time parking stall resource distribution, causes parking lot utilization factor low.
(5) feature of general large parking lot is that floor is many, and area is large, and parking stall is many, storing cycle close and numerous, and all markers are mostly similar, in the time that guest finishes thing and returns to parking lot, often can encounter the puzzlement of seeking car.
Incomplete managing system of car parking, causes driver to find suitable parking lot and parking stall difficulty, stops after entering parking lot, and the spended time of picking up the car is many.Therefore, intelligent parking lot management and the guidance system of Erecting and improving, can not only improve parking lot efficiency of operation, reduces costs enhancement income, and facilitate user to find efficiently suitable parking stall parked vehicles, saves time, and improves user satisfaction.
Summary of the invention
Based on ZigBee wireless technology, design a kind of intelligent parking lot management and guidance system, be intended to make car owner can find fast best parking position, improve parking lot management efficiency.Select ZigBee mesh network as communication network, utilize HC-SR04 type ultrasonic sensor and CC2430 radio-frequency module composition wireless network parking space information collection node, propose optimum berth model based on shortest path first, adopted LED dot matrix to show that information shows and guiding function.Particular content has following 4 aspects.
1. general system proposal design
Intelligent parking position management and guidance system based on ZigBee technology, comprise parking space information detection module, zone controller module, entrance display module, induction display module, central controller etc.System is portal users optimal scheme berth according to current whole parking position occupancy, starts inner part of parking lot guiding display board simultaneously, and user just can park to optimum berth by optimal path.
2. parking space information detection module design
Parking space information detection module is made up of ultrasonic sensor and ZigBee wireless radio frequency modules, adopts higher HC-SR04 type ultrasonic sensor and the CC2430 wireless radio frequency modules of cost performance according to system requirements.
3. Communication Module Design
Intelligent parking position quantity is huge, and system complex needs the data of storage more, has information communication and communication distance feature far away between plurality of devices, selects ZigBee mesh network communication structure.
4. truck space guiding system design
Comprise the design of the determining of optimum parking position model, design, programming and the hardware display screen of parking stall bootstrap algorithm.
