Description
Technical field
The utility model relates to Internet of Things field, particularly, relates to a kind of parking lot dynamic data acquisition device and parking lot dynamic data monitor system.
Background technology
Along with the fast development of Chinese city and improving constantly of people's living standard, urban automobile quantity increases sharply, and the development in parking lot relatively lags behind, and parking difficulty problem becomes increasingly conspicuous, and easily causes traffic congestion.In order to more effectively utilize existing parking resource, need a set of effective city parking inducible system, and the key core of parking guidance system is the collection of parking lot dynamic data.
But, regrettably the parking garage development of most domestic is unbalanced at present, many parking lots cannot realize the information of real-time display residue parking stall, some park constructions comparatively early, hardware condition and software condition more outmoded, the even inside had also is in the original labor management stage, build systematic Park Information Management System also variant, thousands of suppliers fight separately, data interface standard disunity, cause information to interconnect, therefore cause the parking lot dynamic data of magnanimity cannot realize concentrating and sharing, define information island.
Along with the development of Internet of Things and mobile communication technology, sensor is applied to parking lot discrepancy detect, utilize sensor to the motion detection of automobile in gateway, parking lot and the algorithm process of corresponding signal, well can add up and show the situation of residue parking stall, parking lot.
At present, the vehicle passing detection mode applied in parking lot Dynamic Vehicle bit data acquisition method has following several:
(1) ground induction coil detects: under earth's surface, gateway, parking lot, install ground induction coil, Cleaning Principle is that vehicle (metal object) is when sailing the scope of ground induction coil into, coil checker exports a low level signal to controller end, representing now has had car to sail into, but due to itself technology, install and need to destroy road surface, easily affected by environment, not resistance to freezing, saline and alkaline, there is interference between lightning strokes, adjacent windings.The area of ground induction coil laying is simultaneously comparatively large, is all considered to be vehicle and have passed through, so misjudgment phenomenon can be caused to exist, finally cause the error of the parking stall quantity in parking lot for bicycle or tricycle.
(2) infrared detection: be oppositely arranged infrared receiver and transmitter in the horizontal direction of gateway, parking lot, when vehicle passes through, Infrared is interdicted, and namely receiving end sends detection signal.But owing to being subject to the interference of smog, dust, raindrop, and various thermal source (comprising human body, other animals), this kind of scheme causes the probability of erroneous judgement higher.
(3) intelligent video analysis collection: the detection method based on video utilizes camera to carry out image acquisition, Computer Image Processing and mode identification technology is used to identify car plate, to count access information, but this scheme needs the equipment such as supporting ccd video camera, light compensating lamp, video frequency collection card, candid photograph main frame, whole system is huge, easily be subject to daytime/impact at night, and costly.
(4) card taking detects: for the built parking lot having intelligent parking Fare Collection System, its inner part of parking lot judges number of empty spaces certificate by card taking, also card, by mounting software Interworking Data acquisition system, data acquisition is carried out to parking lot, but many parking lot management software disunities, cause and obtain difficulty data.
(5) ultrasound examination: install a ultrasonic probe directly over each parking stall, a probe controller is connected by RS485 bus, the parking space state information collected is carried out gathering, processing, is then connected to acquisition terminal by an other RS485 bus.The data collected are delivered in the PC for managing by serial ports by data processing centre (DPC) in real time.PC and then parking space information is processed, add up.Be published on neighbouring empty parking space display screen by wireless or wired mode by acquisition terminal again, select traffic route to guide driver.Be only applicable to modern newly-built parking lot, and higher being not suitable for of cost popularizes.
Existing parking information perception and inducible system based on the information transmission framework of wire communication, namely obtain parking stall occupied information by the mode of wire transmission usually, then parking space information are sent to advices plate display.Specifically, its implementation is many based on RS485 or RJ45 communication, but these two kinds of communication modes all exist problems such as communication distance is short, a junction nodes limited amount.
