Description

[0002] In the field of manufacturing, especially the manufacturing of some large products (such as automobiles), the number and variety of components that make up such products are large. Therefore, it is necessary to monitor the production process of the product in real time in order to find and solve problems in time.

[0003] For the same type of products, there are different models. When assembling a certain model of product, all the corresponding parts that make up the product need to be placed in the specified location within the specified time so that the staff or production equipment can perform the assembly work.

[0004] However, due to the different product models, the required accessory models are different. During the assembly process, the staff may fail to place the corresponding accessories at the specified location at the specified time, or place the wrong accessory model, which further leads to assembly errors. After completing the assembly process of some accessories or the assembly process of the entire product, when checking again, the products with assembly errors need to be disassembled and then assembled again.

[0071] From the perspective of hardware composition, the server structure can be as follows Figure 2 As shown, it includes a processor 210 , a memory 220 and a communication component 230 .

[0072] The processor 210 may be a CPU (central processing unit) or a SoC (system on chip), etc. The processor 210 may be used to execute various instructions involved in the method, etc.

[0074] The communication component 230 may be a wired network connector, a WiFi (wireless fidelity) module, a Bluetooth module, a cellular network communication module, etc. The communication component may be used to transmit data with other devices, which may be servers or other terminals.

[0075] From the perspective of hardware composition, the structure of the terminal can be as follows Figure 3 As shown, it includes a processor 310, a memory 320, a display component 330, and a communication component 340.

[0076] The processor 310 may be a CPU (central processing unit) or a SoC (system on chip), etc. The processor 310 may be used to execute various instructions involved in the method, etc.

[0077] The memory 320 may include various volatile memories or non-volatile memories, such as SSD (solid state disk), DRAM (dynamic random access memory), etc. The memory 320 may be used to store pre-stored data, intermediate data, and result data during the navigation process, such as map data, navigation voice, etc.

[0080] In addition to the processor and memory, the terminal may also include an audio acquisition component, an audio output component, and the like.

[0081] The audio collection component may be a microphone for collecting the user's voice, and the audio output component may be a speaker, earphone, etc. for playing audio.

[0082] The embodiment of the present application takes an automobile as an example to explain the solution in detail. Other situations are similar and will not be described in detail in the embodiment of the present application.

[0083] In the car production workshop, the production line is divided into multiple production links, each of which is responsible for an assembly step. For example, the first production link of the production line is responsible for assembling seats, and the second production link is responsible for assembling steering wheels. For different models, the models of the same type of parts are also different. For example, different models require different tire models.

[0084] The embodiment of the present application provides a production monitoring method for the above application scenario. The method is applied to a production monitoring system. The processing flow can be as follows: Figure 4 As shown, the following processing steps are included:

[0085] 401. A target UWB tag set on the first component broadcasts a discovery message according to a preset period.

[0086] The first component may be a component of a product. For example, if the product is a car, a tire may be the first component of the product.

[0087] The discovery message carries identification information of the first component.

[0088] In implementation, before the assembly process of the car begins, the identification information of the first component is recorded in the target UWB tag, and the target UWB tag is attached to the first component. The target UWB tag can start broadcasting discovery messages periodically after the binding process is completed; or it can start broadcasting discovery messages periodically after the target UWB tag enters the Bluetooth sensing range of the UWB base station. The period of broadcasting discovery messages is preset, for example, the period can be twenty seconds.

[0089] 402. The UWB base station receives a discovery message and determines a time of receiving the discovery message.

[0090] Among them, the UWB base stations can be distributed in the production workshop according to certain rules, and can be on both sides of the production line, with the UWB base stations on each side arranged at a certain distance.

[0091] In implementation, a UWB base station may receive discovery messages of multiple target UWB tags simultaneously, and a discovery message of a target UWB tag may also be received by multiple UWB base stations.

[0092] 403. The UWB base station sends a notification message to the management device.

[0093] The notification message may carry the receiving time and the identification information of the first component, and may also carry the identification information of the UWB base station.

[0094] There are multiple ways for the UWB base station to send notification messages to the management device.

[0095] Method 1: Every time the UWB base station receives a discovery message, it records the time of receiving the discovery message, and obtains the identification information of the first component from the discovery message, adds the reception time of the discovery message, the identification information of the first component and the identification information of the UWB base station to the corresponding notification message, and sends the notification message to the management device.

[0096] Method 2: Every time the UWB base station receives a discovery message, it records the time of receiving the discovery message, obtains the identification information of the first component from the discovery message, and stores the reception time and the identification information of the first component in correspondence. When the number of discovery messages received by the UWB base station reaches a preset threshold, the UWB base station sends the reception time of these discovery messages, the identification information of the first component, and the identification information of the UWB base station to the management device.

[0097] Method three: Every time a cycle passes, the UWB base station notifies the discovery message received in the cycle. The cycle is preset. Every time the UWB base station receives a discovery message, it records the time when the discovery message is received, and obtains the identification information of the first component from the discovery message. After the UWB base station times a cycle, it adds the identification information corresponding to the discovery message recorded in the cycle and the reception time to the notification message and sends it to the management device.

[0098] 404. The management device determines the location of the first component according to the reception time of the corresponding identification information sent by each UWB base station and the location of each UWB base station.

[0099] In implementation, the management device receives a notification message from a UWB base station, and obtains the identification information of the target UWB tag, the identification information of the UWB base station, and the receiving time of the corresponding identification information from the notification message. The management device pre-stores the corresponding relationship between the identification information of the UWB base station and the location of the UWB base station. Based on the corresponding relationship, the management device can determine the coordinates of the UWB base station. The management device can determine the discovery message corresponding to the same component in the received discovery message within the same broadcast cycle (that is, the identification information of the component carried in the discovery message is the same), and obtain the corresponding receiving time and the identification information of the corresponding UWB base station from it. The receiving time and the coordinates of the corresponding UWB base station are input into the positioning algorithm to calculate the position of the component. The positioning algorithm can be TOF (time of flight), TOA (angle of arrival), TDOA (time difference of arrival) algorithm, etc. The management device stores the calculated position of the first component and the identification information corresponding to the first component in correspondence. When the position of the first component changes, the management device updates the position of the first component in real time.

[0100] 405 , the management device determines the first component type corresponding to the identification information of the first component according to the pre-stored correspondence between the identification information of the component and the component type.

[0101] The first component type may be a material number, which is used to indicate the model or version of a component, and multiple identification information may correspond to one first component type. For example, when producing a car of the same model, the tire types of multiple cars are the same, but the identification information is different. Two tires with identification information of 1000000A and 1000001A respectively correspond to the component type of model A tire.

[0102] In implementation, a correspondence table between component identification information and component types is pre-stored in the management device. After receiving the notification message sent by the UWB base station, the management device obtains the identification information of the first component from it, and based on the identification information, the first component type can be determined by looking up the correspondence table between the identification information and the component type.

[0103] 406. The management device sends the location, identification information, and type of the first component to the first terminal.

[0104] In implementation, the management device may also determine the name, icon, and parameter calibration of the first component based on the identification information of the first component, and send the name, icon, parameter calibration, location, identification information, and type of the first component to the first terminal. The first terminal may be a display screen of a production workshop.

[0105] 407. The first terminal displays the position, identification information, and type of the first component.

[0106] For example, the name of the first component is tire, and the content displayed by the first terminal may be as shown in Table 1.

[0107] Table 1

[0108]

[0109] 408. The management device determines the first production link corresponding to the regional range to which the position of the first component belongs according to the pre-stored correspondence between the production links and the regional ranges.

[0110] In practice, the floor plan of the production workshop is gridded, and each small square corresponds to a coordinate point. The production workshop is divided into multiple areas, some of which correspond to production links. Each production link corresponds to multiple small squares, and the area range corresponding to each production link can be determined based on the coordinates of multiple small squares, such as Figure 5 As shown. The management device stores the identification information of the production link and the coordinates of the corresponding area range accordingly. After the location of the first component is determined, the corresponding area range is determined, and then the production link where it is located is further determined.

[0111] 409. The management device determines the second production link corresponding to the identification information of the first component and the reference time range to which the current time belongs based on the pre-stored correspondence between the identification information of the component, the production link and the reference time range, and determines whether the second production link is the same as the first production link.

[0112] In implementation, the management device pre-stores production plan data, including reference time range, production links, and component identification information, for example,

[0113] Table 2

[0114] Benchmark time frame Production Part identification information 10:10:00—10:15:00 AProduction stage 1000000A 10:30:00—10:45:00 B. Production Link 1000000B …… …… ……

[0115] The management device can obtain the production plan data corresponding to the first production link based on the determined first production link, or obtain the production plan data corresponding to the first component based on the identification information of the first component, or determine the production plan data corresponding to the corresponding reference time range based on the current time.

[0116] 410. If the second production link is different from the first production link, the management device sends a first alarm notification to the first terminal.

[0117] When the production link of the first component at the current time determined by the management device is inconsistent with the production plan data, a first alarm notification is sent to the first terminal, and the first alarm notification carries identification information of the first component.

[0118] For example, the identification information of the first component is 1000000A. Based on 1000000A, it can be determined that the production link of the first component from 10:10:00 to 10:15:00 is production link A. When the management device determines that at 10:11:00, the production link of the first component is production link B, which is inconsistent with the production plan data.

[0119] 411. The first terminal sends a first alarm signal.

[0120] The first alarm signal may be in the form of an image or a sound.

[0121] In implementation, the first terminal receives the first alarm notification, displays the identification information of the first component, the alarm text and the alarm symbol, and may also emit an alarm sound effect at the same time. The alarm text may be "production plan matching error". The display content of the first terminal may be as follows: Figure 6 shown.

[0122] 412, the management device obtains the correspondence between the component types of the components that need to be assembled in the first production link, determines multiple components including the first component that are currently in the first production link, and compares each correspondence item in the correspondence between the component types of the multiple components and the component types of the components that need to be assembled.

[0123] Each corresponding relationship item is composed of multiple component types of components that need to be assembled. Each corresponding relationship item is composed of multiple component types, that is, each corresponding relationship item is a component type set, and the corresponding relationship of the component types of components that need to be assembled in any production link is composed of multiple component type sets. Each component type in any component type set is a component type of each component that participates in the assembly process of the production link.

[0124] The management device may pre-store the corresponding relationship between the identification information of the production link and the component type of the corresponding component to be assembled. The management device may determine the corresponding relationship between the component type of the corresponding component to be assembled based on the identification information of the first production link.

[0125] The management device can determine component types corresponding to the multiple components based on the identification information of the multiple components currently in the first production link, and further compare the multiple component types with each component type set corresponding to the first production link.

[0126] 413: If any of the correspondence items in the correspondence between the component types of the plurality of components and the component types of the components to be assembled do not match, the management device sends a second alarm notification to the first terminal.

[0127] If these multiple component types are exactly the same as the component types in any component type set, it means that the components currently in the first production link are correct and can be processed subsequently without the need for an alarm; if these multiple component types are not exactly the same as the component types in each component type set, a second alarm notification is sent to the first terminal.

[0128] For example, the chassis of the components that need to be assembled in the first production link, the corresponding relationship of the component types of the components that need to be assembled in the first production link includes four corresponding relationship items: A-type chassis-A-type frame, B-type chassis-B-type frame, C-type chassis-C-type frame, and D-type chassis-D-type frame. The component types of multiple components currently in the first production link include B-type chassis and A-type frame, which do not belong to one of the corresponding relationship items of the chassis type, and the matching error is sent to the first terminal. The second alarm notification is sent.

[0129] 414. The first terminal sends a second alarm signal.

[0130] In implementation, when the first terminal receives the second alarm notification, it displays the identification information, alarm text, and alarm symbol of the first component, and may also issue an alarm sound effect or an indicator light alarm. The alarm text may be "Component type mismatch error". The display content of the first terminal may be as follows: Figure 7 shown.

[0131] After the management device determines the first production link corresponding to the area to which the location of the first component belongs, the following steps are also included: Figure 8 The processing flow shown includes the following processing steps:

[0132] 801. If the production link corresponding to the first component determined in the previous cycle is the third production link, the management device sends an assembly completion notification to the first terminal.

[0133] The assembly completion notification carries the identification information of the first component and the identification information of the third production link. The cycle refers to the execution cycle of the above process, which can be considered as the cycle of the management device locating the component, or the cycle of the UWB tag broadcasting the discovery message.

[0134] During implementation, when the production link of the first component changes, the production link of the first component before the change is determined as the third production link.

[0135] For example, when the production link of the tire changes from production link 2 to production link 3, production link 2 is the production link of the tire in the previous cycle, that is, the third production link. The management device adds the identification information of production link 2 and the identification information of the first component to the assembly completion notification and sends it to the first terminal. Correspondingly, in the content displayed by the first terminal, the position of the tire changes from production link 2 to production link 3.

[0136] 802. The first terminal displays an assembly completion prompt message based on the identification information of the first component and the identification information of the third production link.
