The present invention relates to a device checking system and a method thereof, and more particularly to a system of matching segmented words to check correctness of components of a device and a method thereof.
Industry 4.0 (also known as the fourth industrial revolution) is not just creation of new industrial technologies, but focuses on the integration of existing industrial technologies, sales processes and product experience, so as to build a smart factory with adaptability, resource efficiency and ergonomics through artificial intelligence (AI) technology, and integrate customers and business partners in the business process and value process to provide perfect after-sales service, thereby establishing a new intelligent industrial world with perception consciousness.
With the wave of the Industry 4.0 sweeping the world, manufacturers are all using smart manufacturing to optimize production transformation and enhance competitiveness. The smart manufacturing is to realize the intelligent product design and manufacturing, and enterprise management and service based on sensing technology, network technology, automation technology and AI through the processes of perception, human-computer interaction, decision-making, execution and feedback.
The electronic assembly industry has characteristics of small profits but quick turnover and fierce product price competition, so the manufacturers in the electronic assembly industry always pursue more effective control and optimization of raw materials and production tools, thereby maximizing the efficiency of factory production resources. For example, the production line of the electronic assembly industry includes many test stages for various circuit boards; the production line includes the test stage for checking whether the components installed in the completed device match expectations, so as to prevent delivering the device with the wrong assembly from the factory.
The conventional method of checking whether the components in the device match expectations is to execute a specific program installed on the device that has been confirmed to be ready for delivery in advance, to detect component messages of the components installed or set in the device; next, a comparison list is created based on the detected component messages, so that the completed device is compared with the pre-generated comparison list during the production process. The above-mentioned conventional method is to compare the pre-generated list with the component messages of the components actually installed or set in the device; however, when the completed device is installed or set alternative materials due to the expected materials are short, the above-mentioned conventional method will issue a problem of inconsistency in the comparison, and it causes trouble in a production process.
In order to solve the above-mentioned problems, some solutions using databases are developed, for example, a material substitution table of expected materials and alternative materials are created in advance, the pre-created comparison list is compared with the component messages of components actually-installed or set in the device, when the expected material in the comparison list does not match the actual component in the device, the actual component is then compared with the alternative material of the expected material recorded in the material substitution table. However, the above-mentioned solution needs to frequently add and modify alternative materials of expected materials and still requires additional manpower to maintain the material substitution table.
According to above-mentioned contents, what is needed is to develop an improved solution to solve the convention problem of extra manpower and time cost to check the correctness of the components in a device.
An objective of the present invention is to provide a system of matching segmented words to check correctness of components of a device and a method thereof, so as to solve the conventional technology problem that extra manpower and time cost is required to check the correctness of the components in a device.
In order to achieve the objective, the present invention provides a system of matching segmented words to check components of a device, and the system includes a message obtaining module, a bill obtaining module, a word processing module, a word comparing module, and a result determining module. The message obtaining module is configured to obtain a component list of components of a target device, wherein the component list includes component messages. The bill obtaining module is configured to obtain a bill of materials of the target device, wherein the bill of materials records pieces of material data. The word processing module is configured to perform string processing and segmenting on one of the component messages and corresponding material data to generate component key words and the material key words corresponding to the one of the component messages. The word comparing module is configured to compare the component key words and the material key words corresponding to the one of the component message, wherein when a quantity of matched component key words and material key words corresponding to the one of the component messages reaches a quantity threshold, the word comparing module determines that the one of the component messages matches the bill of materials. The result determining module is configured to determine that a check for the target device is passed when all of the component messages match the bill of materials.

The word comparing module 160 is configured to compare the component key words and the material key words generated by the word processing module 150 and corresponding to the component message obtained by the message obtaining module 110, so as to determine whether the component key words and the material key words corresponding to the same component message match each other. It should be noted that, if the component type of the component message is the same as the material type in the material message, the component key words generated by the word processing module 150 according to the component message and the material key words generated by the word processing module 150 according to the material message are corresponding to the same component message. But the present invention is not limit thereto. The word comparing module 160 can also define each material key word one by one as corresponding to each component message for determining whether the material key words match the component key words.
In an embodiment, the word comparing module 160 selects a comparison manner for comparing the component key words and the material key words corresponding to the same component message, based on a data type or both of the data type and a sting length of the component key word. The above-mentioned data type can be, for example, text, number (may contain unit of quantity), date or time, but the present invention is not limited to these examples. The above-mentioned string length can be amount of characters of the component key word and the material key word.
The comparison manner used by the word comparing module 160 will be described in the following paragraphs. For example, when the data type of the component key word is number or date/time, the word comparing module 160 determines whether the component key word and the material key word are the same fully; when the data type of the component key word is text and the string length of the component key word is lower than a character count threshold, the word comparing module 160 determines whether a edit distance between the component key word and the material key word is lower than a distance threshold, or determines whether the material key words contain the component key word, or determines whether the component key words contain the material key word; when the data type of the component key words is text and the string length of the component key word is greater than or equal to the character count threshold, the word comparing module 160 determines, based on a long short term memory (LSTM) model, whether the component key word matches the corresponding material key word; for example, the word comparing module 160 determines whether the data outputted from the LSTM model, which receives the component key word, is the same as the material key word corresponding to the component key word; however, the present invention is not limited to above-mentioned examples.

In an embodiment, the word comparing module 160 can define weights of the component key words generated by the word processing module 150, and when a sum of the weights of the component key words matching the material key words reaches a preset weight count threshold, or the sum of the weights of the matched component key words reaches the weight count threshold, and the quantity of the matching pairs of the component key words and the material key words reaches the quantity threshold, the word comparing module 160 determines that the component message corresponding to the matching pair of the component key words and the material key words matches the bill of materials obtained by the bill obtaining module 130.
When all of the component messages obtained by the message obtaining module 110 match the bill of materials obtained by the bill obtaining module 130, the result determining module 180 determines that a check for the target device 400 is passed; otherwise, the result determining module 180 determines that the check for the target device 400 is not passed.
In an embodiment, the result determining module 180 can determine whether a quantity of the component messages obtained by the message obtaining module 110 is the same as a quantity of the pieces of the material data obtained by the bill obtaining module 130, and when the quantity of the component messages obtained by the message obtaining module 110 is not the same as the quantity of the pieces of the material data obtained by the bill obtaining module 130, the result determining module 180 determines that the check for the target device 400 is not passed. In an embodiment, the result determining module 180 can determine whether the quantity value recorded in the component message is the same as the quantity value recorded in the material data corresponding to the same component message; when the quantity value recorded in the component message is not the same as the quantity value recorded in the material data corresponding to the same component message, the result determining module 180 also determines that the check for the target device 400 is not passed.

In step 250, after the message obtaining module 110 obtains the component list and the bill obtaining module 130 obtains the bill of materials, the word processing module 150 performs a string processing and a string segmenting on the component messages contained in the component list and the material message contained in the bill of materials, so as to generate component key words and material key words after the string processing and the string segmenting. In step 270, the word comparing module 160 defines one of the component messages is corresponded to the material key words generated from the same material message and compares the component key words and the material key words that correspond to the same component message, to determine whether the component key words and the material key words corresponding to the same component message match each other. In step 280, when a quantity of matching pairs of the component key words and the material key words corresponding to the same component message reaches a quantity threshold, it is determined that the component message corresponding to the matching pair of the component key words and the material key words matches the bill of materials.
In this embodiment, the word processing module 150 one by one selects a component message, which is not selected yet from the component list, such as “Samsung Electronics Co. Ltd. M393A4K40CB2-CVF MEMORY MODULE 32 GB PC4-23400R DDR4 288P” (“Samsung Electronics Co. Ltd.” is manufacturer, “M393A4K40CB2-CVF” is component model, “MEMORY MODULE” is component type, “32 GB”, “PC4-23400R DDR4” and “288P” are component specification) and extracts each of the material messages, corresponding to the selected component message from the bill of materials (such as material type included in the material messages is “MEMORY MODULE” or “MEMORY”) or all of the material messages from the bill of materials, if one of the extracted material message is “SAMSUNG M393A4K40CB2 2933MT/s 32 GB 288”, as shown in
After the word comparing module 160 determines whether the component messages of the component list obtained by the message obtaining module 110 match the bill of materials obtained by the bill obtaining module 130 (step 280) and all of the component messages match the bill of materials, the result determining module 180 determines that a check for the target device 400 is passed; otherwise, when at least one of the component messages of the component list does not match the bill of materials, the result determining module 180 determines that the check for the target device 400 is not passed.
As a result, the present invention is able to check whether the components installed and set in the target device 400 match the contents of the bill of materials, even when one of the component is different from the bill of materials.
