Background technology
Steel reel number on the coil of strip is to issue by secondary at present, number print on the coil of strip by jetting device for making number or artificial mark spraying, no matter all need manual confirmation steel reel number whether correct after the number of spray of any mode, because artificial uncertain factor, make mistakes easily and working environment is complicated, temperature is high, have unsafe factor; In addition, the unusual steel reel number that also can cause secondary to issue of the checkout equipments such as Spot Cooling metal detector is detained, make jetting device for making number on different coil of strips continuously ejection identical number, the steel reel number of front is covered by the coil of strip of back, make last volume can not find the position, the wrong volume of a rear curly hair produces the objections such as metering, quality, causes direct economic loss.
Summary of the invention
Technical matters to be solved by this invention provides a kind of cold hot-rolled finished product steel reel number critique system and method, can prevent the quality problems that cause because of jetting device for making number spray mistake.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cold hot-rolled finished product steel reel number critique system is provided, comprise capturing and recognition device, PLC controller and HIM client, described capturing and recognition device is used for obtaining the image of hot cold rolling finished steel coils, and with the digital collection in the image out; Described capturing and recognition device by Ethernet and switch with the digital transmission that collects to described PLC controller; Described PLC controller is used for the numeral that collects is carried out data-switching, and it is contrasted one by one, judges whether the numeral that duplicates; Described HIM client is used for showing the comparative result of PLC controller.
Described cold hot-rolled finished product steel reel number critique system also comprises audible-visual annunciator, and described audible-visual annunciator is reported to the police when the PLC controller is judged duplicate digital.
Described capturing and recognition device comes numeral in the recognition image by the NCC algorithm.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cold hot-rolled finished product steel reel number proofreading method also is provided, may further comprise the steps:
(1) image of the hot cold rolling finished steel coils of collection, and with the digital collection in the image out;
(2) with the digital transmission that collects to the PLC controller;
(3) the PLC controller carries out data-switching to the numeral that collects, and it is contrasted one by one, judges whether the numeral that duplicates;
(4) comparative result of demonstration PLC controller.
Also comprise the step of reporting to the police when the PLC controller is judged duplicate digital in the described step (3).
Pass through the NCC algorithm with the digital collection in the image out in the described step (1).
Beneficial effect
Owing to adopted above-mentioned technical scheme, the present invention compared with prior art, have following advantage and good effect: automaticity of the present invention is high, easy to use, this method adopts the check and correction of full-automatic steel reel number, the operator is at ordinary times without any need for operation with observe, and only need to get final product at the warning message that observing on the man-machine interface after the buzzing chimes of doom appears in red alarm or operator's console appears in picture.Because the present invention adopts the check and correction of full-automatic steel reel number, error rate is low: the mistake of having avoided human factor to cause.The present invention reduces labour intensity, safe, after employing this method, has cancelled traditional artificial scene and has checked the steel reel number, has both reduced manually, reduces dangerous.Carry out more communication work just can accomplish to drive a vehicle work such as check and correction of instruction on basis of the present invention, stop existing artificial check mark etc., secondary development is strong.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is process flow diagram of the present invention.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiments of the present invention relate to a kind of cold hot-rolled finished product steel reel number critique system, as shown in Figure 1, comprise capturing and recognition device, PLC controller and HIM client, described capturing and recognition device is used for obtaining the image of hot cold rolling finished steel coils, and with the digital collection in the image out; Described capturing and recognition device by Ethernet and switch with the digital transmission that collects to described PLC controller; Described PLC controller is used for the numeral that collects is carried out data-switching, and it is contrasted one by one, judges whether the numeral that duplicates; Described HIM client is used for showing the comparative result of PLC controller.
Among Fig. 1, label 1 is an integrated shooting and digital recognition apparatus, and its can be enough be taken pictures and by software with the digital collection in the photo out to object; Label 2 is Ethernets, will take and the equipment of digital recognition apparatus 1 and PLC controller 4 are connected to and carry out data transmission on the switch 3 by netting twine; In PLC controller 4, data are carried out the work such as conversion, comparison, safety, warning output of type; Final data, warning message etc. can output on the man-machine interface 5 by Ethernet 2 communications, observe reference for operating personnel, and if there is Data duplication or mistake, PLC controller 4 also will be exported to audible-visual annunciator 6, with alert.Major function of the present invention records and compares whether duplicate number with several steel reel numbers in the scheduling exactly, causes occurring coil of strip and enters storage mistake, misdelivery etc., produces metering or quality objection.
Described cold hot-rolled finished product steel reel number critique system also comprises audible-visual annunciator, described audible-visual annunciator is reported to the police when the PLC controller is judged duplicate digital, so can notify operating personnel tested cold hot-rolled finished product coil of strip existing problems in the very first time, need to manually check.
Described capturing and recognition device comes numeral in the recognition image by the NCC algorithm.The normalizing eliminate indigestion is relevant to be a kind of related algorithm of typical intensity-based, and its principle is as follows:
