Description

Communication task analysis method, device, and computer-readable recording medium

The present disclosure relates to a communication technology, and more particularly, to a communication task analysis method and device thereof.

In order to achieve industrial automation, when building a production line, engineers will first plan the corresponding information exchange table for each production line equipment in the upper control software. For example, the data exchange block corresponding to equipment A is set in the table. From 2000 to 3000, the data exchange block corresponding to device B is set at positions 3000 to 4000 in the form, and each field in the data exchange block has a clear meaning and data format definition. Thereby, when the upper control unit receives the packets from the device A and/or the device B, it will perform tasks such as task assignment or information exchange according to the message definition in the data exchange block. In the above process, the information exchange table needs to be set manually, which is not only labor-intensive, but also lacks flexibility for modification. In particular, when there are equipment changes on the production line, engineers must re-set and check these equipment. Quite inconvenient. Therefore, it is the current trend to build digital information models corresponding to various industrial equipment.

However, even with the establishment of a digital information model, a globally unified device information model still does not exist. The main reason is that, first, there is a high degree of specificity between devices, and it is difficult to apply a unified model. Second, different industries have different terms and usage habits. Third, even in the same industry, the industry norms adopted are different in different regions, so it is difficult to find a globally common information model as the digital representation of all devices. Therefore, even when devices of the same industry support the same meta-model, the information model will still be presented differently. Not only that, different types of equipment on the production line still have their own supported equipment information models, which are also different from each other, and there are still problems of information exchange and equipment communication tasks analysis and understanding. Based on the above, how to support different types of devices to communicate with less human intervention is a subject of those skilled in the art.

The present disclosure provides a communication task analysis method, a device, and a computer-readable recording medium, so that the devices can achieve autonomous communication through communication task analysis.

The communication task analysis method disclosed in the present disclosure has the following steps: obtaining a correspondence between communication semantic information and device semantic information; receiving a communication packet, wherein the communication packet includes target task information; analyzing the communication packet according to the communication semantic information to obtain the target task information; The correspondence between communication semantic information and device semantic information, Determine whether a candidate device information corresponding to the target task information exists in the device semantic information; in response to the device semantic information existing candidate device information, determine whether the candidate device information is compatible with the target task information; and reply a communication packet according to the judgment result.

The present disclosure also provides a device for performing communication task analysis, and the device has a communication device, a storage device and a processor. The communication device is used for transmitting and receiving packets. The storage device is used to store information. The processor is connected to the communication device and the storage device. The processor is used for executing the following steps: acquiring the correspondence between the communication semantic information and the device semantic information, and storing it in the storage device; receiving the communication packet through the communication device, wherein the communication packet includes the target task information; analyzing the communication packet according to the communication semantic information, to obtain Obtain target task information; according to the correspondence between the communication semantic information and the device semantic information, determine whether there is candidate device information corresponding to the target task information in the device semantic information; in response to the presence of candidate device information in the device semantic information, determine whether the candidate device information is related. containing the target task information; and replying to the communication packet through the communication device according to the judgment result.

The present disclosure also provides a computer-readable recording medium for communication task analysis, having a computer program, and after the computer is loaded and executed, the communication task analysis method provided by the present disclosure can be completed.

Based on the above, in the communication task analysis method, the device for communication task analysis, and the computer-readable recording medium for communication task analysis of the present disclosure, the syntax specification of a general and unified communication protocol is used as the communication protocol between different devices. media to smooth out communication problems caused by grammatical differences between different devices. Therefore, after establishing the corresponding relationship between the communication semantic information and the equipment semantic information, regardless of the design of the production line If equipments and locations are added, removed or changed, common communication semantic information can still be used between equipments to achieve the purpose of communication, establish the ability of independent communication task analysis between equipments, and reduce the need for operators to reset the equipment on the production line. Labor costs.

Device semantic information is based on internationally used object types, attributes, and relationships Type description vocabularies and grammar specifications (Ontology) to build device-related semantic models. For example, among the international grammar standards, the e-commerce quotation field adopts the grammar standard of "GoodRelations", the product description adopts the grammar standard of "eCl@ss", and the manufacturing industry adopts the grammar standard of "RAMI". Therefore, in the following description, the device semantic information will use the syntax specification of "GoodRelations", the syntax specification of "eCl@ss" and the syntax specification of "RAMI" to build a device-related semantic model as the device semantic information. It should be noted that, in this embodiment, the syntax specification of "GoodRelations", the syntax specification of "eCl@ss" and the syntax specification of "RAMI" are adopted, and the architecture of Resource Description Framework (RDF) is adopted. It is expressed in combination with the above-mentioned types of grammar specifications. However, in other embodiments, the device semantic information can be constructed through more grammar specifications, or the device semantic information can also be constructed through other grammar specifications or expressions, and the present disclosure is not limited thereto.

For example, the equipment semantic information has a drilling service class (Class), and under this service class, there is a manufacturing function tag defined by "RAMI", such as <RAMI: TechnologyFunctionality>. In addition, this service class also has a product/engineering feature attribute defined with "eCl@ss", for example, <eCl@ss:P_BAF455001>. This service class also has construction prices defined in "GoodRelations", eg <GoodRelations:UnitPriceSpecification>. In addition, this service category also adds information about device control, for example, the tag <eCl@ss:P_BAG064001> is used to indicate that if the location of a specific memory block in the device is manipulated, the drilling service can be activated. service. In other embodiments of the present disclosure, labels under the service category are added, decreased, and changed according to the service category, but the present disclosure is not limited thereto.

The communication semantic information is used to parse the packet through the communication semantic information after receiving the packet. That is to say, the semantic information of communication is equivalent to the internal intermediary layer between the internal resources of the device and the external communication. Therefore, the communication semantic information can use an international standard way to interpret the content of the packet, such as the VDI2193-1/2 international standard, or, the communication semantic information can also use the content customized by the device to define the communication semantics. Any semantic information that understands the contents of the packet can be used in the communication semantic information.

In an embodiment of the present disclosure, the communication semantic information is also defined using a resource description framework. In addition, those with semantic information in the packet structure will be established as the class of the communication ontology. For example, information such as the communication purpose (Purpose)/communication object (Object)/communication sender/receiver (Receiver/Sender) is established as a communication packet ( Sentence), and designates the code or string used for the purpose of communication in the communication specification (for example: "request/cancel service", "get/set/delete/query/subscribe" data, "notify", etc.) as the communication The purpose category resource item. For example, one of the categories in the communication semantic information is "Purpose", and the annotations under it are, for example, "rdfs:Contains "Failure"^^xsd:string", "rdfs:Contains "Propose" ^^xsd:string", "rdfs:Contains "Confirm"^^xsd:string", "rdfs:Contains "RejectProposal"^^xsd:string", "rdfs:Contains "NonUnderstand"^^xsd:string", " rdfs:Contains <Query"^^xsd:string", "rdfs:Contains "Inform"^^xsd:string", "rdfs:Contains "Cancel"^^xsd:string", "rdfs:Contains "AcceptProposal"^^xsd:string", "rdfs:Contains "CallForProposal"^^xsd:string", "rdfs:Contains "Agree"^ ^xsd:string", "rdfs:Contains "Refuse"^^xsd:string", "rdfs:Contains "Agree"^^xsd:string", "rdfs:Contains "Subscribe"^^xsd:string"... etc., of course, the present disclosure is not limited to this.

In addition, the communication device 110 is equipped with supportable communication interfaces 111a and 111b. For example, if the communication device 110 is a communication chip using an Ethernet network, the communication interfaces 111a and 111b use RJ45 connectors, for example, and support an interface of the Ethernet network. In this embodiment, the communication interface 111a is connected to an external network to receive communication packets from other devices and include target task packet information. The communication interface 111b forms an internal network with other devices to issue device control commands to other devices. Detailed details will be explained later. It should be noted that the communication interfaces 111a and 111b may be of the same type or different types, and the present disclosure is not limited thereto. And, as shown in Figure 1, The number of the communication interface 111a connected to the external network and the number of the communication interface 111b connected to the internal network is one each. However, in other embodiments, the number of the communication interfaces 111a and 111b may also be multiple, and the present disclosure is not limited to this. .

The storage device 120 is used for storing information, in particular, the storage device 120 stores software, data and various codes required for communication task analysis, such as device semantic information and communication semantic information. The storage device 120 can be any type of fixed or removable random access memory (Random Access Memory, RAM), read-only memory (Read-Only Memory, ROM), flash memory (flash memory), hard disk (Hard Disk Drive, HDD), Solid State Drive (Solid State Drive, SSD) or similar components or a combination of the above components.

It is worth mentioning that, in this embodiment, the storage device 120 uses a database system to store device semantic information and communication semantic information, and supports query in the resource description framework, such as the query language of SPARQL, but this disclosure does not limited to this.

The processor 130 is connected to the communication device 110 and the storage device 120, and is used for performing necessary operations for communication task analysis. The processor 130 may be a central processing unit (CPU), or other programmable general-purpose or special-purpose microprocessors (Microprocessors), digital signal processors (DSPs), programmable A chemical controller, an application specific integrated circuit (ASIC) or other similar components or a combination of the above components, the present disclosure is not limited thereto.

Alternatively, in yet another embodiment of the present disclosure, the apparatus 100 for performing communication task analysis is a machine that operates independently and coordinates multiple operating parts of itself. This disclosure is not so limited.

FIG. 2 is a schematic flowchart of a communication task analysis method according to an embodiment of the present disclosure. In this embodiment, the communication task analysis method is at least applicable to the apparatus 100 shown in FIG. 1 , but the present invention is not limited thereto. The details of the method for analyzing the communication task completed by the apparatus 100 will be described below in conjunction with FIG. 1 and FIG. 2 .

In step S210, the processor 130 acquires the correspondence between the communication semantic information and the device semantic information.

In an embodiment of the present disclosure, the details of the correspondence between the communication semantic information and the device semantic information obtained by the processor 130 are illustrated by FIG. 3 . Please refer to FIG. 3 . FIG. 3 is a schematic flowchart of a part of a communication task analysis method according to an embodiment of the present disclosure. In step S310, the processor 130 acquires device semantic information and communication semantic information. In detail, the processor 130 can download various syntax specifications from the Internet to store each syntax specification in the storage device 120 . Alternatively, various types of grammar specifications may be transmitted and stored in the storage device 120 in advance at the time of delivery or through the operation of the operator.

In addition, the processor 130 also acquires equipment-related information, including equipment items and equipment parameters. An item of equipment refers to a specific piece of equipment or a specific machined part of the apparatus 100 . As mentioned above, if the device 100 is a stand-alone machine, the equipment items correspond to specific processing parts of the device 100, such as drilling parts, Grinding parts, etc. Alternatively, if the apparatus 100 is a bridge for coordination and communication among multiple devices, the corresponding items of the equipment items are, for example, but not limited to, drilling machines, grinding machines, pressing machines, etc., which the present disclosure is not limited to. In this embodiment, the device item can be defined by, for example, the device's Internet Protocol Address (IP address), a specific communication port, and the device name in the local area network. Equipment parameters are the specifications of the equipment/processed components themselves and the service specifications they can provide. In detail, when the equipment leaves the factory, the operator will first establish the size, circuit design, operation rules, service content, unit cost, etc. of the machine in the storage device 120 as equipment parameters. Alternatively, when it is detected that the device is connected to the processor 130 for the first time, the processor 130 may connect to a designated website through the communication device 110 to download information related to the device, which is not limited in the present disclosure. For example, equipment-related information such as "Equipment A provides drilling services, and the diameter of the drilling holes is about 0.5-3 cm." Using various types of grammar specifications, the processor 130 can convert the device-related information into a unified representation to form device semantic information. As mentioned above, the semantic information of equipment, for example, uses RAMI to define the service category of drilling, and uses eCl@ss to define the diameter of 0.5-3 cm, so as to associate the equipment defined by various types of grammar specifications with equipment. The information is stored as device semantic information.

It is worth mentioning that, in an embodiment of the present disclosure, the processor 130 also displays a user interface through an embedded or external display device, so that the operator can input device-related fields through a standard and a field corresponding to a syntax specification. information. In this way, the processor 130 can quickly convert the device-related information into specific information according to each field. A given grammar specification can be expressed uniformly, but the present invention is not limited to this.

Similarly, the processor 130 can download the communication semantic information from the Internet, or obtain the communication semantic information through the operator, and details are not described here.

In step S320, the processor 130 obtains the communication items allowed by each equipment item in the equipment semantic information. For example, the device can accept a communication item for drilling items such as "request service", and the device cannot accept communication items for drilling items such as "modify the value of maximum drilling allowed". The processor 130 can obtain the permitted communication items of each equipment item in the equipment semantic information by using the information stored in the storage device 120 or receiving the input from the operator, but the present invention is not limited thereto.

In step S330, the processor 130 adds the tags of the communication items allowed by the equipment item to the equipment parameters respectively, so as to establish a corresponding relationship between the equipment semantic information and the communication semantic information. As mentioned above, if the device can accept the communication item for the drilling project as "request service", at this time, the processor 130 will add a <COMM: CallForProposal> tag statement under the drilling category to indicate that the allowable target is "request service". service" communication packet. By adding a tag of the permitted communication service represented by the communication semantic information to the equipment item, the corresponding relationship between the equipment semantic information and the communication semantic information can be established and stored in the storage device 120 .

In another embodiment of the present disclosure, the correspondence between the communication semantic information and the device semantic information can be established in advance and added to the storage device 120 by the operator. Or, in another embodiment of the present disclosure, the correspondence between the communication semantic information and the device semantic information can be automatically analyzed and established by means of machine learning.

In this embodiment, the communication packet has target task information. The target task information indicates the purpose of the communication packet, for example, to request a drilling service. The communication packet described here is expressed in the packet structure. For example, the structure of the communication packet can be expressed as Table 1:

The sender ID is the device that initiates the communication packet, that is, the device that requests to execute the target task, and the destination ID is the ID of the device 100 . In an embodiment of the present disclosure, the sender ID and the destination ID may be represented by the device names of different devices in the local area network, or by the IP address or the Media Access Control Address (Media Access Control Address) of the device. , MAC address), the disclosure is not limited to this. The message code is a code indicating the type of the packet, which is well known to those in the communication field and will not be described in detail here. The target is, for example, "request service"; the corresponding item is, for example, "drilling hole"; the target object is, for example, the ID of a specific target, an unlimited object (broadcast), or a description of a feature, so that the processor 130 can search; The target parameter is, for example, 2.5 cm. This disclosure is not limited to this example. In other embodiments, the fields of the communication packet can be freely changed, increased or shortened, and are not limited to the communication packet structure in Table 1.

In step S230, the processor 130 parses the communication envelope according to the communication semantic information package to get target task information. Specifically, the processor 130 disassembles the packet structure, describes the communication packet with communication semantic information, and obtains corresponding target task information. For example, the parsed communication packet includes the following target task information: "Purpose": "CallForProposal", "DataElement": {"SubModell": "drilling"}, {"PropertyID": "ID_Drilling"}, {" PropertyID":"0173-1#02-BAF455#004","Value":2.5},{"PropertyID":"0173-1#02-AJ214#002","Value":1.75}. The target task information means that the purpose of this communication packet is to request a service, the service item is drilling, the task object (ie, the equipment requested for the service) has the function of drilling, and the task content (ie, the requested service) The diameter of the drilled hole is 2.5 cm and the thickness is 1.75 cm.

In step S240, the processor 130 determines whether there is candidate device information corresponding to the target task information in the device semantic information according to the correspondence between the communication semantic information and the device semantic information. In detail, as mentioned above, the communication packet has been parsed with the communication semantic information, and the task object and task content are obtained. The storage device 120 also stores the device semantic information of the device machine, and there is a corresponding relationship between the communication semantic information and the device semantic information. Therefore, the processor 130 can automatically search for a candidate equipment item corresponding to the task object in the equipment item according to the task object. In an embodiment of the present disclosure, the processor 130 uses the query language of SPARQL to cross query the communication semantic information and the device semantic information to find the task object. According to the foregoing example, the processor 130 searches for objects that provide drilling services, and takes objects with drilling services as candidate equipment items, and each candidate equipment item and The corresponding device parameters are the candidate device information.

If it is determined that there is no candidate device information corresponding to the target task information, or the processor 130 cannot correctly parse the target task information, so that the processor 130 cannot determine whether there is candidate device information corresponding to the target task information, the processor 130 will The return task rejects the packet to reply to the communication packet.

In step S250, in response to the presence of candidate device information in the device semantic information, the processor 130 determines whether the candidate device information is compatible with the target task information. For example, if there are three candidate equipment items, the processor 130 will respectively determine whether the equipment parameters corresponding to the candidate equipment devices are compatible with the task content in the target task information, that is, whether the drill hole diameter is 2.5 cm and the thickness is 1.75 cm. service.

In step S260, the processor 130 replies the communication packet according to the judgment result. That is, if the equipment parameter corresponding to the candidate equipment item does not include the task content, the processor 130 will return the task rejection packet accordingly to reply the communication packet. However, if the equipment parameter corresponding to the candidate equipment item includes the task content, the processor 130 will return a task reply packet. It should be noted that the content of the task reply packet will be adjusted according to practical needs. For example, in an embodiment of the present disclosure, when the processor 130 determines that the device parameter corresponding to the candidate device item includes the task content, the processor 130 does not require the candidate device information to execute the task. Instead, the processor 130 adds cost information, time information, etc. in the candidate device information to the content of the task reply packet, so as to provide information such as the cost and time required by the source device of the communication packet to perform the task, and thereby, Let the source device of the communication packet decide whether to use one of the candidate equipment items to execute the task.

In another embodiment of the present disclosure, when determining that the device parameter corresponding to the candidate device item includes the task content, the processor 130 converts the target task information into a device control command according to the device semantic information, and sends the device control command to this in the candidate equipment item, so that the candidate equipment item can execute the task content. When the candidate device finishes executing the task content, the processor 130 will receive a task response message (eg, the task has started to be executed, the task has been completed, etc.) from the candidate device item. At this time, the processor 130 sends a task reply packet through the communication device 110 to reply that the source device task of the communication packet has started/completed, and the present disclosure is not limited to the foregoing embodiment. It is worth mentioning that, if there are multiple candidate equipment items, the processor 130 will select one of the candidate equipment items to execute the task content according to the cost information, time information, schedule information, etc. in the candidate equipment information. limited to this.

FIG. 4 is a schematic diagram of an apparatus for performing communication task analysis according to yet another embodiment of the present disclosure. Referring to FIG. 4 , the device 400 for performing communication task analysis in this embodiment includes a device body 410 a , a device body 410 b , a device body 410 c and a main control device 420 .

The device bodies 410a-410c are used to receive communication packets from the master device, and can provide specific services. For example, but not limited to, the device bodies 410a-410c are respectively a press machine, a drilling machine and a grinding machine, and operate independently of each other. In the following description of the hardware of the device bodies 410a-410c, the device body 410a will be described, but the device bodies 410b-410c will have similar hardware, and the device body 410a has the communication device 412, the storage device 414 and the processor 416. The communication device 412 , the storage device 414 and the processor 416 are similar to the communication device 110 and the storage device in the embodiment of FIG. 1 120 and the processor 130 are not repeated here. In addition, the device bodies 410a to 410c can be implemented by at least the device 100 shown in FIG. 1 , but the present disclosure is not limited thereto.

The main control device 420 is a device that sends out communication packets, and is connected to the device body 410a for communication through a communication interface 411a connected to an external network. Taking the manufacturing industry as an example, there is an identification tag on each workpiece, for example, a one-dimensional barcode, a two-dimensional barcode, or a radio frequency identification tag (Radio Frequency Identification tag, RFID tag). The main control device 420 has a label reading device corresponding to the type of identification label. By reading the identification label, the main control device 420 can track the processing progress of the workpiece and its processing flow, and determine what the next processing station for the workpiece is. The main control device 420 will generate and send a communication packet based on the next processing station of the workpiece. For example, if the workpiece has just been processed by the pressing machine, and the next processing station is drilling, at this time, the main control device 420 is the pressing machine, and sends a communication packet to other machines to request the drilling service.

Or, in other situations, such as smart home appliances, when the sweeping robot completes the sweeping process, it will send a communication packet to other devices to request mopping.

Alternatively, the main control device 420 may also be a central control device for sending communication packets and integrating the responses of the machines to complete the service process, but the present disclosure is not limited thereto.

FIG. 5 is a schematic flowchart of a communication task analysis method according to another embodiment of the present disclosure. The communication task analysis method in FIG. 5 is at least applicable to the apparatus 400 in FIG. 4 , but the present disclosure is not limited thereto. 4 and FIG. 5 will be used together to describe the device of this embodiment. 400 Runs the details of the communication task parsing method. It should be noted that in the following description, the device bodies 410a to 410c are respectively described as a pressing machine, a drilling machine and a grinding machine, and the communication packet is used to request the drilling service, and the drilling machine is used for drilling. The diameter of the hole is 2.5 cm and the thickness is 1.75 cm.

In step S510, the device bodies 410a-410c respectively acquire the correspondence between the communication semantic information and the device semantic information, and store them in their respective storage devices. The device bodies 410a to 410c are different machines, respectively, and the control instructions and applicable grammar specifications may not be exactly the same. Therefore, the device bodies 410a to 410c all have a unique correspondence between the communication semantic information and the device semantic information. . The details of the corresponding relationship between the device bodies 410 a to 410 to obtain their own communication semantic information and the device semantic information are the same as those of step S210 in FIG. 2 and the schematic flowchart in FIG. 3 , and will not be repeated here.

In step S520, the main control device 420 sends the communication packets to the device bodies 410a-410c, so that the respective processors of the device bodies 410a-410c receive the communication packets through the respective communication devices. As mentioned above, the main control device 420 determines the target task information contained in the communication packet according to the schedule. Moreover, in this embodiment, the main control device 420 transmits the communication packets to the device bodies 410a-410c by means of broadcasting. The structure of the communication packet has been described in detail in step S220 in FIG. 2 , and will not be repeated here.

In step S530, the device bodies 410a-410c respectively parse the communication packets according to the communication semantic information to obtain target task information, that is, request drilling services, and the diameter of the drilling holes is 2.5 cm and the thickness is 1.75 cm. The details of performing this step for each device body 410a-410c are similar to those of step S230 in FIG. 2, and are not repeated here. described.

In step S540, the apparatus bodies 410a-410c respectively judge whether there is candidate device information corresponding to the target task information in the device semantic information according to the corresponding relationship between the communication semantic information and the device semantic information. The details of each device body 410a-410c performing this step are similar to step S240 in FIG. 2, and will not be repeated here.

In step S550, the apparatus bodies 410a-410c, in response to the presence of candidate device information in the device semantic information, determine whether the candidate device information is compatible with the target task. The device body 410b further determines whether its equipment parameters are compatible with the target task, that is, whether its drilling capability satisfies that the diameter of the drilling hole is 2.5 cm and the thickness is 1.75 cm. The details of this step performed by the device body 410b are similar to those of step S250 in FIG. 2 , and are not repeated here.
