Description
Technical field
The present invention relates to object state identification technology, be specially a kind of object type and location status recognition methods.
Background technology
Currently, object multimode identification is mainly applied and is arranged multiple sensor, provides control signal for automatically identifying, as
The multi-mode input of controller identification equipment, the method system complex, price is higher simultaneously, is difficult in the environment that space is crowded
Installing and implement, the sensor dependability being simultaneously arranged on for a long time in vehicle environment is the highest.
As patent documentation 201110165079.X discloses a kind of parking stall status identification means and method, it includes monolithic
The circuit board of machine minimum system, CCD camera, video signal separating chips, a/d converter, MAZ485 conversion chip.This parking
Position status identification means and method are by one white segment of paint on the ground on parking stall, it is provided that parking stall is the most occupied
Visual signal, thus calculated and self-adaptative adjustment by the image dynamic thresholding of specific environment, it is judged that the idle condition on parking stall.
Which uses image recognition, causes systematic comparison huge, it is achieved to get up and have certain difficulty, and costly.
Summary of the invention
It is an object of the invention to provide object type, location status that a kind of composition is simple and convenient to operate, is easily achieved
Know method for distinguishing, it is achieved thereby that object type, location status reliably and quickly identify, it is ensured that automatic flow operation is the most real
Execute.
The technical solution realizing the present invention is as follows:
A kind of object type and location status recognition methods, it is by feedback signal socket, feedback signal cable, feedback signal
Collection recognition unit constitute, feedback signal socket is arranged on object, feedback signal gather recognition unit include acquisition module and
Identification module, acquisition module is provided with feedback signal acquisition channel, and port number is not less than 2, and each passage arranges Phototube Coupling and filters
Ripple and arrange thresholding, feedback signal is input to central processing unit (CPU) after passage Phototube Coupling filtering.
Recognition methods is to select different points to carry out paired short circuit on feedback signal socket, and short circuit signal is as object type
The feedback signal source of type and location status, when object is connected with any feedback signal cable by feedback signal socket, accesses anti-
When feedback signal gathers recognition unit, short circuit signal input high level VCC is defined as " 1 ", short circuit signal input low level when being not connected with
Signal definition is " 0 ", and short circuit signal incoming level generates and accesses feedback signal Xi, and it is paired that identification module will access feedback signal Xi
Carry out permutation and combination coding, form different types of information coding X1, X2 ... Xn, realize information by software programming code and compile
Code, simultaneously to it is unlikely that information coding be defined as " fault ", just can draw type and the location status of object.
Compared with prior art, its remarkable advantage is the present invention: 1, simple in construction, it is simple to realize.2, applied range, expansion
Malleability is strong, is suitable for object various states identification system.3, reliability is high, easy to operate, it is easy to accomplish automation mechanized operation.
Accompanying drawing explanation
A kind of object type of Fig. 1 and the schematic diagram of location status recognition methods
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further described.Should be appreciated that specific embodiment described herein, and need not only in order to explain the present invention
In limiting the present invention.
As it is shown in figure 1, enumerate a kind of A, B amphitypy object type and the identification embodiment of location status.
A kind of object type and location status recognition methods, it is by feedback signal socket 1, feedback signal cable 2, feedback letter
Number gather recognition unit 3 constitute；Recognition methods is to select different some ai, bi to carry out paired short circuit on feedback signal socket 1
As the feedback signal source of object type and location status thereof, gather recognition unit 3 when feedback signal cable 2 accesses feedback signal
After, feedback signal gathers recognition unit 3 and obtains short circuit signal and be identified, and exports recognition result.
Feedback signal gathers recognition unit 3 and is made up of acquisition module and identification module, and acquisition module is provided with 4 feedback signals
Acquisition channel, each passage arranges Phototube Coupling filtering and arranges thresholding, and short circuit signal is through each passage Phototube Coupling and filters
Being input to identification module after ripple, feedback signal is carried out permutation and combination coding by identification module in pairs, just can draw the type of object
And location status.
The state identification method workflow that the present invention provides, such as corresponding on feedback signal socket 1 a1 and b1, a2 and b2
Short circuit respectively, when object is connected with any feedback signal cable 2 by feedback signal socket 1, receives feedback signal collection identification
After unit 3, feedback signal gathers recognition unit 3 and obtains short circuit signal, generates object type and the access signal of location status
Input_Xi, accesses signal Input_Xi and forms access feedback signal Xi by being input to CPU after Phototube Coupling, filtering, identify
Access feedback signal Xi is carried out permutation and combination coding by module in pairs, forms different types of information coding X1, X2 ... Xn, passes through
Software programming code realizes information coding, thus identifies object type and location status.
It is 2.2k Ω that feedback signal gathers the resistance R1 value of recognition unit 3, and electric capacity C1 value is 0.1uF, and resistance R2 takes
Value is 909 Ω, and diode V1 value is 1N4005, and optocoupler V2 value is that TLP521-1, CPU use STM32F107VCT6, resistance
R3 value is 2.7k Ω.Resistance R1 plays metering function, and electric capacity C1 plays the shake producing input signal and interference signal is filtered
Ripple, resistance R2 rises provides a threshold voltage to input signal, thus compresses the linear amplification region of optocoupler, it is provided that more satisfactory
Transmission characteristic, improves the capacity of resisting disturbance gathered, and diode V1 rises and prevents the voltage negative punching of input signal and putting of protection optocoupler
Optical diode is not broken down by high-voltage, and optocoupler V2 plays the Phototube Coupling effect of input signal, and CPU plays the collection of signal and processes work
With.
A, B amphitypy object type, right position and with or without having nine kinds of states, according to accessing feedback signal Xi, in conjunction with shape
It is as follows that state classification and combination logic permutation and combination carry out coding:
It is X0 that A type object is placed on the access feedback signal on the left side；
It is X1 that A type object is placed on the access feedback signal on the right；
It is X2 that Type B object is placed on the access feedback signal on the left side；
It is X3 that Type B object is placed on the access feedback signal on the right.
When object is connected with any feedback signal cable 2 by feedback signal socket 1, receive feedback signal collection identification list
After unit 3, input high level VCC is encoded to " 1 ", and being not connected with input low level Signal coding is " 0 ", and feedback information encodes such as table 1
Shown in.
Table 1 feedback information encodes
The above is one embodiment of the present of invention, but the present invention should not be limited to this embodiment and accompanying drawing institute
Disclosure.So every without departing from the equivalence completed under spirit disclosed in this invention or amendment, both fall within the present invention and protect
The scope protected.
