Abstract
The invention relates to a vehicle state and information identification extracting apparatus. The apparatus detects the parking state of vehicles in a detected area and displays the parking state through an indicating lamp, image information is sent to an access bus according to an instruction of a host computer, and a control instruction of the host computer can be received to enable state information to be displayed. The apparatus comprises an MCU, an image sensing assembly, an ultrasonic detection assembly, a logic control module, a communication assembly, an indicating lamp assembly, a power supply module, etc. Ultrasonic reflection is adopted to detect whether vehicles exit in the detected area, a result is displayed by the indicating lamp and also sent as feedback to the host computer through a communication port, and when the host computer orders the apparatus to send image signals to a bus on the basis of task scheduling situations, the MCU enables signals of the image sensing assembly to be accessed to the bus through the logic control module, and the bus is released if a command of the host computer is cancelled. In this way, a parking lot guiding and vehicle tracking comprehensive system can be easily formed. The mode of the apparatus is formed by an ultrasonic mode and an image mode both of which are effective simultaneously, and the bus control is employed, so the comprehensive cost and the reliability are both guaranteed.
Description
Technical field
The present invention relates to the image information source of parking space detector, license plate recognition device, be specifically related to a kind ofly determine storing cycle state fast by supersonic sounding and utilize the device of mode bus output image information.
Background technology
At present, market there is the device of multiple independent detection parking position state, although the detection of parking space state can be realized, but the limitation being limited to cost and technological means obtains the characteristic informations such as car plate while not easily realizing obtaining storing cycle state fast and accurately, or monomer high cost or application solution wiring complicated.
Based on the similar products of full images recognition technology, comprehensive wiring is complicated, and recognition speed all there are certain requirements the illumination of vehicle and background, when light is dark or mistake is strong, recognition efficiency all can decline, although there is technical method can correction-compensation, practical application effect still there are certain requirements illumination.Product completely based on supersonic sounding then quick and precisely can detect vehicle-state, but cannot realize image acquisition and the identification of simple wiring condition.
The present invention integrates multiple technologies means and multiplexed resource cleverly exactly, thus while obtaining ultrasonic detection accuracy rate and speed, can complete again the function of image acquisition by the simple routing network of its structure.Therefore quick guided vehicle will be provided to enter and facilitate driver can find vehicle fast and leave these two functions and combine and provide the effective solution in front end, and simplify system architecture, reduce system cost.
Summary of the invention
In order to comprehensively solve the problem of looking for room and looking for car, this two classes related application merges by the present invention, uses supersonic sounding vehicle-state, and extracts vehicle characteristic information by image acquisition for identifying, realize one fore device, and adopt mode bus effectively to save wiring cost.
In order to achieve the above object, the technical solution used in the present invention is as follows:
Region is detected by ultrasonic continuous detection, in real time result pilot lamp is displayed, conveniently look for the driver of parking stall in passage, observe the situation of empty parking space, pass through communication port, state is up to host computer, host computer orders this device that image is sent into bus according to demand, now completes picture catching and identifies.Process rear release bus.
In bus, other same apparatus are processing or are transmitting when taking bus, and do not affect the supersonic sounding of local device, result of detection still can be shown by pilot lamp immediately.
When bus free, host computer is ACTIVE CONTROL, can require that any one has the device of image information demand to provide image information to bus.Communication like this and image are all by bus transfer, and wiring cost will significantly reduce, and acquisition mode can not be made simultaneously to indicate cause time delay because bus time-sharing is multiplexing
Image sensing assembly can be video camera and video acquisition module, also can be imageing sensor.When for video camera, switched by analog switch and realize the coupling of bus, release, use.Different device shared buses gathers respectively.If imageing sensor then switches the image acquisition that corresponding digital channel realizes different passage.
Image sensing assembly and MCU use logic module to be connected and realize switching and controlling.MCU comprises CPU (central processing unit), the parts such as RAM (storer), I/O (input and output), CPU working procedure, complete the interpretation of result of supersonic sounding, make the control actions such as taking of bus and release by communication port according to the order received; I/O is used for being connected with peripheral circuit, completes necessary input/output function.
Multiple devices are by arranging communication protocol address to distinguish, and different address then shows as the device being arranged on diverse location in systems in which.
Indicating lamp component drives corresponding pilot lamp light or glimmer according to result of detection by driving circuit, can indicate parking space state by different conditions or color.Such as green expression room, red expression is occupied.
Compared with prior art, two kinds of application demands combine by the present invention cleverly, optimize solution, add the function of system while decreasing number of devices, not only increase reliability and reduce system cost in the present invention.Also be complete to seek car function when storing cycle guiding function and personnel leave the theatre on applying simultaneously.

MCU be process, control needed for hardware core;
Image sensing assembly is made up of one or more image acquisition units, and each elementary area is responsible for image physical quantity to be converted to electric signal, is connected with seizure collecting unit by bus interface;
Supersonic sounding assembly is the seizure condition utilizing hyperacoustic reflect detection appointed area.
Communications component comprises communication interface and protocol stack, communication scheduling task dispatching software module;
Indicating lamp component is the circuit of the multiple pilot lamp controlled by the I/O of MCU;
Power module is that the unit of this device is powered.
As shown in Figure 2, in typical system composition, unit based on the present invention, it provides parking space state information to application system.Region acquisition controller in application system is collected the state of each base unit and is caught image, stores these information of each parking stall, other management datas are sent to corresponding sniffer and other same level end devices simultaneously, thus composition comprehensive application system.In practical engineering application, distribution density of the present invention is the highest, and the proportional distribution in parking stall, construction wiring amount is maximum, but can obviously save wire rod and construction volume with after mode bus, also accessible other-end device at the same level, therefore significantly can simplify construction and reduce costs.
