Description

Technical Field

[0001] The present invention relates to the technical field of digital factories, and in particular to an intelligent interactive system for digital factories. Background Art

[0002] Digital Factory (DF) is a comprehensive network composed of digital models, methods and tools, including simulation and 3D / virtual reality visualization, integrated through continuous and uninterrupted data management. Digital Factory integrates product, process and factory model databases, improves product quality and quality and dynamic performance involved in the production process through advanced visualization, simulation and document management, and provides comprehensive manufacturing process management. Before the actual product is produced, the entire virtual production process is completed in a computer simulation environment to generate various process data and documents required for actual production that have been verified by the "digital factory". Although professional software such as CAD and PDM that focus on product design have a history of 20 to 30 years since their birth, for a long time, due to the lack of scientific and effective data collaborative management methods, the product data and information generated in the R&D design stage cannot be synchronized with the subsequent production planning and production execution links. Production can only be arranged through the experience and judgment of the staff responsible for production. All problems caused by information asymmetry can only be passively responded to and handled, which not only seriously affects the actual production efficiency, but also requires the additional cost losses caused by it. This kind of problems caused by the disconnection of data and information between product design and manufacturing links is a major pain point in the manufacturing industry.

[0003] The existing patent, with the announcement number CN116307621A, discloses a smart factory production system, including a management system, an intelligent logistics system, a manufacturing execution system and an automation system.

The smart factory production system uses four major systems to create a digital factory through horizontal value chain integration and vertical integration, realize production and operation management automation, and use intelligent, modular, and networked production systems and processes to realize smart factories; and then complete intelligent manufacturing with production logistics management, human-computer interaction and automation integration; and use centralized stacking and robots with movable rails to reduce material transportation personnel and material warehouse personnel.

[0004] Although the above application can realize the automation of production operation management and utilize intelligent, modular, and networked production systems and processes, in actual application, it is not convenient to carry out intelligent management of the project, which affects the overall management of the factory and reduces the convenience of using the system.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] According to the attached Figure 1-2 As shown, an embodiment of the present invention provides a digital factory intelligent interaction system, including a central processing unit, and the output end of the central processing unit is respectively provided with an editing module, a timing module, a data transmission interface, a data storage module, a data transmission module, a data transmission unit, a data sharing unit, a learning module, an allocation module and an activity protocol module.

[0029] The factory intelligent interactive system also includes a system establishment layer, a remote control layer and an intelligent equipment layer. The system establishment layer includes a control terminal, a central processing unit, an operation processing unit and a storage unit. The remote control layer includes an intelligent gateway and a distributed server. The intelligent equipment layer includes intelligent devices.

[0030] By adopting this interactive system, in actual application, it is convenient to carry out intelligent management of the project, which will not affect the overall management of the factory and improve the ease of use of the system. At the same time, the search method is optimized by using the binary search idea to improve the efficiency and stability of solving the simplest operation node. The purpose of solving the simplest operation node is to use the simplest operation node to improve the accuracy and efficiency of control, skip most of the redundant and invalid control nodes, and improve the overall control efficiency.

[0031] The editing module is bidirectionally connected to the central processing unit, the timing module is bidirectionally connected to the central processing unit, the data transmission interface, the data storage module and the data transmission module are all bidirectionally connected to the central processing unit, the input end of the data transmission unit is signal-connected to the output end of the central processing unit, the output end of the data transmission unit is signal-connected to the input end of the data sharing unit, the output end of the data sharing unit is signal-connected to the input end of the learning module, the output end of the learning module is signal-connected to the input end of the allocation module, the output end of the allocation module is signal-connected to the input end of the active protocol module, the output end of the active protocol module is signal-connected to the input end of the data transmission module, and the input end of the central processing unit is signal-connected to the output end of the active protocol module.

[0032] Through this system and management method, the remote control layer can realize the simplest operation node calculated by the model construction layer, and remote control of the intelligent equipment layer can be achieved by sending control instructions or control data through the system establishment layer. The system establishment layer builds a digital factory intelligent manufacturing execution system with intelligent optimization scheduling and quality control as the core, which is conducive to improving key technologies such as equipment and quality control in the lithium battery material industry, and driving the innovation and application of safe and controllable intelligent equipment.

[0033] As the preferred embodiment of the present invention, the timing module is a timer based on the MCU module. In the MCU (M16), the timer is an independent module. M16 has three independent timer modules, namely T / C0, T / C1 and T / C2; T / C0 and T / C2 are both 8-bit timers, and T / C1 is a 16-bit timer. The timer is a hardware module that runs independently of the CPU.

[0034] It is worth mentioning that when TCCRO! =0x00 In any mode, as long as the MCU is powered on, T / C starts timing. In fact, TCCR0 is mainly used to set the pre-scaling, waveform mode and comparison match mode of the timer. When it comes to pre-scaling, we have to mention this module. This module is shared by T / C0 and T / C1, but it can have different frequency division settings. Among the three parameters of TCNT0, OCRO and TIMSK, TCNT0 is used to set the initial timing value of the timer. After the timer starts working, it accumulates from TCNT0 to 0XFF immediately. The time consumed by the accumulation process is the timing time we need; OCRO is a comparison setting value. When the value of TCNTO accumulates to OCR0 (TNCT0==OCRO), if the comparison match interrupt function is turned on, a comparison interrupt will be generated at this time. Therefore, the value of OCRO is generally set between the initial value of TCNTO and 0XFF. Any value outside of this value will not generate a comparison interrupt. TIMSK is an interrupt enable bit setting, that is, when we need a timer overflow interrupt or a comparison match interrupt function or both, we set the corresponding register bit of TIMSK.

[0035] A timer can have two interrupt resources available, one is overflow interrupt, and the other is comparison match interrupt. As mentioned above, the overflow interrupt subroutine should have the initial value of TCNTO overloaded, otherwise, TCNTO will count up from 0X00 to 0XFF, and the time consumed is not the time we want. The comparison interrupt is when TCNT0 == 0CRO, a comparison match interrupt occurs. Therefore, only a small amount of processing code is generally inserted in the interrupt subroutine, otherwise, the so-called interrupt nesting will occur. Since M16 does not support interrupt nesting, this will make some codes in the interrupt subroutine unable to execute, and in severe cases, it will cause the system to crash.

[0036] Conversion of TCNTO and OCRO values: For an 8-bit timer, TCNTO can generally be converted by the following formula: TCNT0 = 256-(TV*F) / N; TV: the desired timing time, unit, usF: crystal frequency (MHz) N: division factor The timer runs independently, it does not take up CPU time, does not require instructions, and only needs to participate when calling the corresponding register.

[0037] As the preferred embodiment of this invention, the data transmission interface is used to connect the computer dictionary with the PC, so as to realize uploading and downloading, data synchronization and convenient electronic book use; it is a data interface for mutual transmission between two machines and exchange of information. The data transmission interface is an interface for connecting the electronic book reader with other devices such as personal computers. With this interface, the electronic book reader and other devices can realize uploading and downloading, data synchronization and other functions. Common data transmission interfaces of PDA include USB interface, serial port, infrared interface and Bluetooth interface.

[0038] As a preferred embodiment of this invention, the data storage module adopts a data acquisition module. Data acquisition is a bridge connecting the computer with the external physical world. The data acquisition module is composed of sensors, controllers and other units. Data acquisition cards, data acquisition modules, data acquisition instruments, etc. are all data acquisition tools.

[0039] It is worth noting that the data acquisition module is a communication module based on the remote data acquisition module platform. It integrates communication chips, storage chips, etc. on a circuit board, so that it has the functions of sending and receiving short messages, voice calls, data transmission, etc. through the remote data acquisition module platform. The remote data acquisition module can realize the main communication functions of ordinary remote data acquisition module mobile phones, and can also be said to be a simplified version of the mobile phone. Computers, single-chip microcomputers, and ARM can be connected to the remote data acquisition module through the RS232 serial port, and various voice and data communication functions can be realized through the AT command control module. The remote data acquisition module technology is a more advanced mobile communication technology compared to GSM. In addition to the small radiation of the remote data acquisition module; in terms of data transmission, the remote data acquisition module 20001X is also significantly different from GPRS in technology. In terms of transmission rate, 1X is almost 3-4 times the speed of GPRS. It is mainly used in the industrial module application field of data transmission and has obvious advantages in speed over the GPRS module. However, the application of remote data acquisition modules in the industrial field lags far behind the application of GPRS modules. The main reason is that on the one hand, the coverage and construction of the remote data acquisition module network are not as perfect as the GSM network. On the other hand, the cost of remote data acquisition modules was at least 2-4 times higher than that of GSM modules in the early days, which made the production cost much higher.

[0040] As a preferred embodiment of the present invention, the data storage module model is OTHER brand 12TB, its cache capacity is 256MB, the hard disk capacity is 12TB, and the hard disk rotation speed is 7200 rpm.

[0041] As a preferred embodiment of this invention, the data transmission module adopts a 4G data transmission module, such as DATA-6105, which supports 7-mode full network access and can flexibly select operators. It also provides convenient docking tools, such as protocol development kit and network to serial port tool, to facilitate docking with the host computer software.

[0042] It is worth mentioning that a data transmission module is an electronic device that can transmit data from one place to another. These modules are often used in Internet of Things (IoT) applications, such as remote data acquisition, smart irrigation, centralized meter reading, industrial control, etc. The functions and features of the data transmission module may include support for multiple communication protocols, such as GPRS, CDMA, LoRa, NB-IoT, etc., which can realize remote transmission of data. Acquisition function: It can collect serial port device data, such as serial port instruments, collectors, PLCs, etc. Remote management function: Support remote parameter setting, program upgrades, etc., for easy maintenance and management. Low power design: Suitable for battery-powered or solar-powered application sites, which helps to reduce energy consumption and costs. Industrial-grade design: Suitable for harsh outdoor environments with high stability and reliability. Data transmission modules are an important part of IoT applications. They realize remote data transmission through wireless or wired methods, which improves the efficiency and convenience of data acquisition and transmission.

[0043] As the preferred embodiment of this invention, the data transmission unit supports dual-channel data transmission via GPRS / CDMA / 3G and short messages, supports multi-center data communication, can collect data from serial port devices such as serial port instruments, collectors, PLCs, etc., supports remote parameter settings and program upgrades during remote management, and supports multiple networking modes such as fixed IP, VPN, and domain name resolution.

[0044] As a preferred embodiment of the present invention, the technical parameters of the data transmission unit are as follows: the data format is 8 data bits, the stop bit (1, 2) can be set, the check bit (odd, even, none) can be set, the baud rate: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400 (Bit / S) is optional, the communication bit error rate: ≤10-6, the power supply: 10V~30V DC, the average current: <70mA / 12V, the working environment: the temperature: -40~+85℃, the humidity: ≤95%.

[0045] When in use, a digital factory intelligent interactive system of the present invention transmits a signal to a central processing unit through an editing module, and then a timing module performs a timing operation on it. Data is transmitted through a data transmission interface, and the processed data is transmitted through a data transmission unit, and then enters a data sharing unit, and then a comparison and learning is performed through a learning module, and then an allocation operation is performed on it through an allocation module. The allocated data is subjected to a protocol operation through an active protocol module, and the data is first transmitted to the central processing unit, and then the data is transmitted back to the active protocol module through a data transmission module. The processed result is stored through a data storage module. During use, the central processing unit is controlled through a control terminal, and then the processing unit and the storage unit are operated to build a system establishment layer, and then the intelligent gateway is controlled through a remote control layer, and then the distributed server is controlled to achieve remote control. The distributed server after remote control sends instructions to the intelligent device to achieve control of the intelligent interactive system.
