Abstract

The invention relates to the field of parking space detection, and especially relates to a parking lot management method based on an automobile electronic identification. The management method is realized by establishing and assembling a functional module structure, and is achieved mainly through a computer program stored in a computer readable storage medium. The method adjusts the intensity of harmonics transmitted by an identification reader in real time according to the data of air humidity so as to enable the harmonics with different intensities transmitted by the identification reader to achieve stable communication quality under different propagation losses. Therefore, even if the data of air humidity is large, the method will also reduce the errors of test results, thereby improving the accuracy of parking management.

Description

Parking lot management method and apparatus based on vehicle electron identifying

Technical field

The present invention relates to parking detection field, particularly relate to parking lot management method based on vehicle electron identifying, this pipe Step in reason method, can set up functional module, be combined into functional module construction, mainly deposits by being stored in computer-readable Computer program in storage media realizes.

Background technology

At present, increasingly mature along with vehicle electron identifying technology, vehicle electron identifying technology has low cost, the most easily With, it is widely applied to the monitoring field of intelligent transportation.Although there being the signal sent by detection vehicle electron identifying at present Intensity level judges the parking lot management method of the stand of vehicle, but the communication of vehicle electron identifying and identification reader Quality is unstable, as easy as rolling off a log is affected by environmental change, so that testing result exists bigger error, thus impact stops The accuracy of parking lot management.

Summary of the invention

It is an object of the invention to provide the parking lot based on vehicle electron identifying that communication quality is stable, reduce detection error Management method.

Inventor it has been investigated that, vehicle electron identifying is affected by environmental change with the communication quality of reader, its root This reason is that the propagation of different medium is consumed difference by electromagnetic wave, due to roadside environments when being installed on the reader communication in roadside Changing, electromagnetic wave propagation medium also changes, thus causes different propagation to be consumed, and now reader is launched identical Harmonic wave intensity may result in the difference of communication quality under consume different propagation, inventor also finds the crowd at roadside air In multimedium, electromagnetic wave propagation consume is affected by air humidity occupies the overwhelming majority, propagates consumption when air humidity increases Damage and substantially become big, propagate consume when air humidity reduces and substantially diminish.The present invention proposes techniques below scheme accordingly:

The present invention provides parking lot management method based on vehicle electron identifying, including:

Reference intensity presets step: when vehicle travels to ad-hoc location, by now detect by described vehicle electron identifying The signal strength values sent is recorded as reference signal intensity level;

Positioning step: if the signal strength values detected is not changed in preset duration, then according to reference signal intensity level and The signal strength values detected in real time is to judge the stand of this vehicle;

This management method also includes regulating harmonic wave intensity step: the humidity data regulation mark according to detecting in air in real time is read Read the harmonic wave intensity that device is set out.

Wherein, in regulation harmonic wave intensity step, specifically, if described humidity data is higher than preset value, then increase described Harmonic wave intensity exports;If described humidity data is less than preset value, then reduce the output of described harmonic wave intensity.

Wherein, this management method also includes leaving step: if detected signal strength values decays to less than threshold value, then sentence The disconnected already out parking stall of this vehicle, described threshold value adjusts with the change of described reference signal.

For the step in the management method that the present invention is given, functional module can be set up, be combined into functional module construction, Mainly realized by the computer program stored in a computer-readable storage medium.

Beneficial effect: base of the present invention parking lot management based on vehicle electron identifying method, the present invention is by according to air In humidity data adjust the harmonic wave intensity that identification reader is launched in real time so that identification reader launches different harmonic wave intensity Propagate consume be issued to stable communication quality different, accordingly even when be air humidity data relatively big in the case of, also can Reduce the error of testing result, thus improve the accuracy of parking management.

Detailed description of the invention

The invention will be further described with the following Examples.

Arranging an identification reader at ad-hoc location, this identification reader outwardly broadcast type sends harmonic wave, works as vehicle When travelling to ad-hoc location, it is loaded into the electronic mark on this vehicle and can receive the harmonic wave of this identification reader and make back Should, the signal strength values sent by vehicle electron identifying detected by now this identification reader is recorded as reference signal strong Angle value;Preferably, ad-hoc location is set in the porch in parking lot, and every chassis is required for through porch, only need to be signal Detection equipment is located at that porch is other just can thus set up reflecting of every chassis specific reference signal intensity level and same distance Penetrate relation, in conjunction with detecting that the signal strength values that every chassis is sent judges its particular location in real time.In this identification reader Digital humidity sensor Real-time Collection air in humidity data and be transferred to control system, control system is according to being received Humidity data regulate the harmonic wave intensity that this identification reader is set out, if humidity data is higher than preset value, then increase harmonic wave strong Degree output;If described humidity data exports less than preset value, then reduce described harmonic wave intensity, so make this identification reader send out Penetrate different harmonic wave intensity to propagate consume be issued to stable communication quality different, accordingly even when be air humidity data relatively In the case of great, it may also reduce the error of testing result, thus improve the accuracy of parking management.

If detected signal strength values decays to less than threshold value, then judge the already out parking stall of this vehicle.Threshold value is with described The change of reference signal and adjust, benefit is to improve the reliability judged.After judging that vehicle leaves parking stall, system just terminates Charging also calculates the Parking Fee of this vehicle, and this stand is shown after manager, or this parking stall is other Display lamp is lighted, to show that this parking stall does not has vehicle, so that car owner can be quickly found out vacant parking stall.

During this enforcement makes, show the situation of parking of parking stall, the benefit side of being in real time according to all detected signal strength values Just user knows the automobile parking situation on different parking stall, parking lot in real time with manager.

For the step in the management method that the present invention is given, functional module can be set up, be combined into functional module construction, Mainly realized by the computer program stored in a computer-readable storage medium.

Last it should be noted that, above example is only in order to illustrate technical scheme, rather than the present invention is protected Protecting the restriction of scope, although having made to explain to the present invention with reference to preferred embodiment, those of ordinary skill in the art should Work as understanding, technical scheme can be modified or equivalent, without deviating from the reality of technical solution of the present invention Matter and scope.
