Description
Technical field
The present invention relates to object state identification technology, specially a kind of object type and location status recognition methods.
Background technique
Currently, mainly multiple sensors are arranged in application to the identification of object multimode, provide control signal for automatic identification, as
Controller identifies the multi-mode input of equipment, this method system complex, while price is higher, is difficult in the crowded environment in space
Installation is implemented, while the sensor use reliability of long-term installation in a vehicle-mounted environment is not high.
If patent document 201110165079.X discloses a kind of parking stall status identification means and method, it includes monolithic
Circuit board, CCD camera, vision signal separating chips, converter, the MAZ485 conversion chip of machine minimum system.The parking
Whether occupied position status identification means and method provide parking stall by the paint one white segment on the ground on parking stall
Visual signal judges the idle state on parking stall to calculate by the image dynamic thresholding of specific environment and adaptively adjust.
Which uses image recognition, causes systematic comparison huge, implements with certain difficulty, and is costly.
Summary of the invention
The purpose of the present invention is to provide a kind of object type, location status for constituting and being simple and convenient to operate, being easily achieved
Know method for distinguishing, object type, location status are reliable and quickly identification, guarantee automatic flow operation are effectively real to realize
It applies.
Realize that technical solution of the 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
Recognition unit is acquired to constitute, feedback signal socket is mounted on object, feedback signal acquisition recognition unit include acquisition module and
Identification module, acquisition module are equipped with feedback signal acquisition channel, and port number is not less than 2, and each channel is arranged Phototube Coupling and filters
Wave and setting thresholding, feedback signal are input to central processing unit (CPU) through channel Phototube Coupling and after filtering.
Recognition methods is that different points is selected to be shorted on feedback signal socket in pairs, is shorted signal as object type
The feedback signal source of type and location status, when object is by feedback signal socket and any feedback signal cable connection, access is anti-
It is shorted signal input high level VCC when feedback signal acquires recognition unit and is defined as " 1 ", signal input low level is shorted when being not connected with
Signal definition is " 0 ", is shorted signal incoming level and generates access feedback signal Xi, it is pairs of that identification module will access feedback signal Xi
Permutation and combination coding is carried out, different types of information coding X1, X2 ... Xn is formed, realizes that information is compiled by software programming code
Code, while " failure " is defined as to the information coding that can not occur, it just can obtain the type and location status of object.
Compared with prior art, the present invention its remarkable advantage is: 1, structure is simple, is easy to implement.2, have a wide range of application, expand
Malleability is strong, is suitable for object various states identifying system.3, high reliablity, it is easy to operate, it is easy to accomplish automatic operation.
Detailed description of the invention
The schematic diagram of Fig. 1 a kind of object type and location status recognition methods
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
As shown in Figure 1, enumerating the identification embodiment of a kind of A, B amphitypy object type and 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 acquisition recognition unit 3 constitute；Recognition methods is that different point ai, bi is selected to be shorted on feedback signal socket 1 in pairs
As the feedback signal source of object type and its location status, recognition unit 3 is acquired when feedback signal cable 2 accesses feedback signal
Afterwards, feedback signal acquisition recognition unit 3, which obtains, is shorted signal and is identified, exports recognition result.
Feedback signal acquisition recognition unit 3 is made of acquisition module and identification module, and acquisition module is equipped with 4 feedback signals
Acquisition channel, each channel are arranged Phototube Coupling and filter and be arranged thresholding, be shorted signal and through each channel Phototube Coupling and filter
Identification module is input to after wave, feedback signal is carried out permutation and combination coding by identification module in pairs, just can obtain the type of object
And location status.
State identification method workflow provided by the invention, such as a1 and b1 corresponding on feedback signal socket 1, a2 and b2
It is shorted, is connect when object passes through feedback signal socket 1 with any feedback signal cable 2 respectively, be connected to feedback signal acquisition identification
After unit 3, feedback signal acquires recognition unit 3 and obtains short circuit signal, generates the access signal of object type and location status
Input_Xi, access signal Input_Xi form access feedback signal Xi, identification by being input to CPU after Phototube Coupling, filtering
Module carries out permutation and combination coding for feedback signal Xi is accessed in pairs, forms different types of information coding X1, X2 ... Xn, passes through
Software programming code realizes information coding, to identify object type and location status.
The resistance R1 value that feedback signal acquires recognition unit 3 is 2.2k Ω, and capacitor C1 value is 0.1uF, and resistance R2 takes
Value is 909 Ω, and diode V1 value is 1N4005, and optocoupler V2 value is TLP521-1, and CPU uses STM32F107VCT6, resistance
R3 value is 2.7k Ω.Resistance R1 plays metering functions, and capacitor C1 plays the shake generated to input signal and interference signal is filtered
Wave, resistance R2, which rises, provides more satisfactory input signal one threshold voltage of offer to compress the linear amplification region of optocoupler
Transmission characteristic improves the anti-interference ability of acquisition, and diode V1, which rises, prevents the voltage negative of input signal from rushing and protecting putting for optocoupler
Optical diode is not broken down by high-voltage, and optocoupler V2 plays the Phototube Coupling of input signal, and CPU plays the acquisition of signal and processing is made
With.
A, B amphitypy object type, left-right position and whether there is or not sharing nine kinds of states, according to access feedback signal Xi, in conjunction with shape
State classification and combinational logic permutation and combination encode as follows:
The access feedback signal that A type object is placed on the left side is X0；
The access feedback signal that A type object is placed on the right is X1；
The access feedback signal that Type B object is placed on the left side is X2；
The access feedback signal that Type B object is placed on the right is X3.
It is connect when object passes through feedback signal socket 1 with any feedback signal cable 2, it is single to be connected to feedback signal acquisition identification
After member 3, input high level VCC is encoded to " 1 ", and being not connected with input low level Signal coding is " 0 ", feedback information coding such as table 1
It is shown.
1 feedback information of table coding
The above is one embodiment of the present of invention, but the present invention should not be limited to the embodiment and attached drawing institute
Disclosure.So all do not depart from the lower equivalent or modification completed of spirit disclosed in this invention, guarantor of the present invention is both fallen within
The range of shield.
