The specific embodiment of the present invention applied to the apparatus is substantially the same as the following embodiments of the method for preventing error of checking the application components, and will not be described herein again.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a component checking and error preventing method of the present invention, wherein the component checking and error preventing method includes the following steps:
step S100, scanning a part and recording part information corresponding to the part;
a component is generally a constituent part for constituting a whole, and is a most basic constituent part directly constituting a finished product, but it is not necessarily a part unlike a part, and may be a semi-finished product or a finished product of another company. Different from the raw material, the material is a component which can be directly assembled or used on a finished product after being processed or formed, and the component comprises a part, a purchased semi-finished product and a purchased finished product. In vehicle manufacturing, a component may refer to vehicle components such as an engine, a transmission, a drive shaft, an engine main harness, a starter harness, and an ECU (Electronic Control Unit). The machine vision technology mainly uses a computer to simulate the visual function of a human, extracts information from an image of an objective object, processes and understands the information, and finally is used for actual detection, measurement and control. In this embodiment, an engine is used as a description of a component, engine component information is acquired by a machine vision technology, and specifically, component information may be acquired by setting a visual identification code reader, a light source, and a visual identification error-proofing PLC (Programmable Logic Controller) industrial personal computer. The engine part code is scanned by the visual identification code reader, and the part code information corresponding to the engine is input into the system. For example, under a visual light source, an engine part code is acquired by using a visual camera, and part code information corresponding to the engine is recorded by a visual recognition error-proofing PLC industrial personal computer connected with the visual camera.
Step S200, acquiring preset production indication information, and determining a matching rule according to the production indication information;
the production instruction information refers to information corresponding to related production activities to be performed by currently performed production activities, and when checking the parts of the vehicle, the related production instruction information preset by the current vehicle is acquired, and corresponding part checking rules, namely matching rules, are determined according to the production instruction information. Since factors such as the model, arrangement, component mounting position, and number of vehicles do not always match each other every time component matching is performed, matching rules required for component matching for different production instruction information are different. The method for determining the matching rule according to the production instruction information may be to acquire the required configuration information in the production instruction information and determine the matching rule corresponding to the configuration information, may be to set different program numbers corresponding to different matching rules, generate the production instruction information including the program number, determine the matching rule corresponding to the program number by acquiring the production instruction information including the program number, or may be to directly include the matching rule corresponding to the vehicle component in the production instruction information, or other methods for determining the matching rule according to the generation instruction information.
Step S300, judging whether the production indication information is matched with the part information according to the matching rule;
after the matching rule is determined, whether the obtained production instruction information is matched with the obtained part information or not is judged under the matching rule. The matching rule can be a rule for comparing the characteristic value information such as the length and the number of bits of the bar code in the component information with the characteristic value information such as the length and the number of bits of the bar code in the production indication information; or a rule for comparing a specific value corresponding to the specified position of the data string in the acquired part information with a specific value corresponding to the same position of the data string in the production instruction information; or determining whether the repetition rate of the data corresponding to the production indication information and the data corresponding to the part information reaches a preset value or not.
And step S400, if yes, the component information is determined to be correctly checked.
If the matching is successful, the part checking information is determined to be correct, namely, the part information is correctly checked. If the matching fails, the part information check is determined to have errors, and further processing is needed. And after the component information is correctly checked, outputting related prompts so that the production activity enters the next process. For example, it is determined that the parts information is correctly checked, a signal is returned to the production indicating system, a tower lamp corresponding to the production indicating system is controlled to be green, and green background information and text information of 'the parts information is consistent with the production indication' are displayed through a display. And after the part information is checked to have errors, outputting a corresponding prompt to enable a manager to process in time. For example, a check error of the part information is determined, a tower lamp corresponding to the production instruction system is controlled to be turned on in red, and text information of "the part information is consistent with the production instruction" is displayed through a display.
Referring to fig. 3, in an embodiment of the present invention, when a production operation starts, the indicator light of the production system is controlled to turn on blue to prompt that the operation is entered, and the industrial personal computer obtains production indication information and converts the production indication information into information to be checked; acquiring part information through a scanning component; the system compares whether the information to be checked is consistent with the part information, if so, PASS is displayed and a passing signal is sent to a production indicating system so that a production indicating lamp is green to prompt that the checking is correct, and the next trolley works; if not, the abnormity is confirmed, the abnormity information is displayed and stored, the production indicator lamp is turned on red to prompt the checking error, the production line is stopped during control, and calling is carried out to wait for the manager to process the abnormity.
In the embodiment of the invention, the parts are scanned, the corresponding part information is recorded, after the production instruction information is obtained, whether the production instruction information is matched with the part information or not is judged according to the matching rule corresponding to the production instruction information, and if the production instruction information is matched with the part information, the part information can be determined to be correctly checked. Whether the part information is matched with the production information is determined by calling a matching rule corresponding to the production indication information, so that the part information is automatically checked, the situation of potential quality hidden danger caused by false identification or missing identification during manual checking is avoided, and the part information checking efficiency and the part information checking accuracy are improved.
Further, based on the first embodiment of the component checking and error preventing method of the present invention, a second embodiment of the component checking and error preventing method of the present invention is provided, where in the step S200, preset production instruction information is obtained, and refinement of the matching rule is determined according to the production instruction information, including:
step a, determining a program number corresponding to the production indication information;
the program number is a program number corresponding to an application program used for component collation, and since there are variations such as vehicle type change and component change, different collation rules are set for different vehicle types and components, and different program numbers are associated with different collation rules. And after the production indication information is acquired, determining a program number corresponding to the production indication information. Specifically, the corresponding program number may be determined according to configuration system information and production indication bit information included in the production indication information.
And b, calling a matching rule associated with the program number in a preset rule base.
The system is provided with a rule base in advance, different coding rules, namely matching rules, are output according to different configurations, each program number corresponds to different matching rules, and after the program number is determined, the matching rules associated with the program number are called.
The method has the advantages that a plurality of different matching rules are set for different checking objects, the phenomenon that an engineer needs to develop and modify an application program again when the checking objects are changed can be avoided, the matching rules are actively adjusted on a system interface, the secondary development cost of the system is reduced, and the quick change of the checking objects such as vehicle types and parts can be automatically coped with.
Further, the step of recording the part information corresponding to the part comprises:
step c, acquiring part information corresponding to the part, and extracting part information characteristic values in the part information;
and d, recording the characteristic value of the part information to a database.
After the part information is acquired, extracting a part information characteristic value corresponding to the part information according to a preset analysis standard, wherein the part information characteristic value is a characteristic value which is set aiming at a matching rule and contains part information characteristics, and the part information characteristic value represents a part corresponding to the current part information. The pre-configured analysis standard may be characteristic value information such as a bar code length and a digit number corresponding to the part code in the acquired part information. And storing the part information characteristic value into a database, and displaying the part information characteristic value to a main interface through a display.
By acquiring the part information characteristic value, the part information characteristic value can be used for checking in the subsequent checking of the part information, so that the system resource is saved, and the checking speed is improved.
Further, the step of judging whether the production instruction information is matched with the part information according to the matching rule comprises the following steps:
step e, converting the production indication information into the information of the parts to be checked according to the matching rule;
f, extracting characteristic values of the information to be checked in the information of the parts to be checked;
after the component checking error prevention system receives the production indication information, the corresponding program Number value, the serial Number, the VIN (Vehicle Identification Number) and the bar code information related to the program Number are obtained through analysis based on the production indication information, the analyzed related information is displayed on a main interface through a display, and at the moment, the information related to the program Number corresponding to the production indication information is called as the component information to be checked. And extracting a to-be-checked information characteristic value corresponding to the to-be-checked part information according to a preset analysis standard, wherein the to-be-checked information characteristic value is a characteristic value which is set aiming at a matching rule and contains the to-be-checked part information, and the to-be-checked information characteristic value represents the required part information corresponding to the current generation indication information. The part information characteristic value is consistent with the characteristic type corresponding to the information characteristic value to be checked, for example, the part information characteristic value and the information characteristic value to be checked are both the bar code length of the part code.
And g, judging whether the part information characteristic value is matched with the information characteristic value to be checked.
And comparing the part information characteristic value with the information characteristic value to be checked so as to judge whether the part information characteristic value is matched with the information characteristic value to be checked, wherein the comparison mode is to determine whether the part information characteristic value is consistent with the information characteristic value to be checked, if so, the matching is successful, and if not, the matching is failed.
The matching judgment is carried out by obtaining the information characteristic value, whether the part checking is wrong or not is automatically identified, the checking accuracy is improved, the determination working time is saved, and the part checking efficiency is improved.
Further, if yes, after the step of determining that the part information check is correct, the method further includes:
h, recording and outputting verification passing information;
step i, sending a passing signal to a production indicating system;
and j, controlling the production indicating system to adjust the state of the indicating lamp corresponding to the production indicating system to be a passing state according to the passing signal.
And after the component information is confirmed to be checked correctly, generating component checking passing information, recording the passing information, outputting the checking passing information through a display and/or a loudspeaker, and sending a passing signal to a production indicating system, wherein the production indicating system adjusts the state of a corresponding indicator light into a passing state after receiving the passing signal, and then enters the next trolley operation. For example, after the component information is successfully checked, the system displays "PASS" and the indicator light of the production indicating system is changed to green to indicate that the current check is passed and the next vehicle operation can be performed.
The passing information is displayed through the indicating lamp, the checking progress of the parts is fed back, the production plan can be regulated and controlled in time, and the production progress is ensured.
Further, after the step of determining whether the production instruction information matches the component information according to the matching rule, the method further includes:
step k, if not, determining that the checking fails;

and m, controlling the production indicating system to monitor whether a passing signal exists in real time, wherein when the production indicating system does not monitor the passing signal within the preset time, the state of an indicating lamp corresponding to the production indicating system is adjusted to be an early warning state, and the production system is controlled to stop the production line.
When the matching of the production instruction information and the component information fails, the component is determined to be failed to be checked and abnormal, the checking failure information is stored, the checking failure information is output through a display and/or a loudspeaker, the checking failure is sent to the Andong system, and the checking failure information is output through the Andong system. The preset time refers to a preset monitoring time of the production indicating system, the production indicating system starts to monitor whether the passing information exists after the production indicating information and the part information start to be matched, if the passing information is not received after the preset time is exceeded, the production indicating system determines that the checking fails, at the moment, the state of the corresponding indicating lamp is adjusted to be an early warning state, and the production system is controlled to stop the current production line operation. And the manager can perform corresponding processing when receiving the early warning signal. For example, after it is determined that the parts information collation has failed, the system displays "NG", and an indicator lamp of the production indication system is turned red to indicate that the current collation has failed. In another embodiment, when the checking fails, failure information can be sent to the production indicating system, and the production indicating system adjusts the state of an indicator lamp corresponding to the production indicating system to be in an early warning state according to the failure signal and controls the production system to stop the production line. After the administrator processes the checking failure items, the reset key on the main interface of the anti-error system for checking the parts can be triggered, the related information of the part codes is cleared, the indicator light corresponding to the production indication system is reset, the production indication system waits for the production indication system to issue production indications again, and the related information such as the corresponding serial number, VIN code and program number of the vehicle is refreshed on the software interface after the new production indication information is received. The system also has an information record query function, wherein data can be queried through query conditions, such as bar code information of an input part, namely the writing time and state corresponding to the bar code information, the corresponding bar code data and the like can be queried. And when the information is wrong, modifying, inquiring corresponding information, modifying, storing data and updating. And part code information corresponding to the vehicle type, the new production indicator and the program number can be set, and the types and information of the compared parts can be added or modified.
And outputting early warning information after the checking fails, timely reminding relevant personnel to process, avoiding quality hidden danger, and avoiding the situation that the production line is pulled and stopped and a manager is called only by the conscious and execution force of the operator, possibly causing the untimely stopping of the production line, so that the information of outflow of poor-quality products appears, thereby ensuring the product quality.
