Description

A functionally configurable digital control system for accelerator

Technical Field

The present application relates to the field of industrial digital control, and in particular to a functionally configurable digital control system for an accelerator.

Background technique

Industrial control systems mainly refer to systems that automatically control industrial production processes, aiming to ensure the efficiency, safety and product quality of the production process. The system involves a variety of technologies and components, such as sensors, actuators, controllers, communication networks, etc. These components and technologies can work together to automate and optimize the production process. For example, sensors can monitor various parameters in the production process, such as temperature, pressure, liquid level, etc., and convert these parameters into recognizable signals. Actuators can take corresponding actions based on these signals, such as adjusting valves, controlling switches, etc., to keep the production process stable and efficient.

With the development of computer technology, communication technology and control technology, the traditional control field is undergoing an unprecedented transformation and is beginning to develop in the direction of networking. Industrial control system is a composite interdisciplinary subject that integrates modern control theory, modern network communication technology, industrial automation, industrial big data, industrial Internet of Things, industrial cloud, information security and computer technology. Industrial control system mainly includes three functions:

Display function: The display function has the ability to observe the current status of the automation system in real time and provide information or diagrams to the operator so that the operator can respond.

Monitoring function: The monitoring function focuses on a critical value, such as pressure, temperature, level, etc., compares the current value with the predefined threshold, and issues an alarm or interaction based on the set monitoring function.

Control Function: The control function is where things are controlled, moved, activated and started, enabling the control system to make the actuator engage, the valve open, the motor run, etc.

However, in the current industrial control system applications, the main hardware control system used is PLC (Programmable Logic Controller), which is an application system composed of a main control chip and peripheral circuits. It can pre-program instruction flows through programs to achieve specific functions. It is usually used in automation, industrial control and other fields. Its characteristics are high reliability, easy programming and use, but it also has relatively obvious disadvantages. For example, PLC is generally used to implement simple logic and complete control functions. It is difficult to implement artificial intelligence and adaptive learning algorithms in the future, and the control application scenarios are relatively narrow. In addition, there are relatively few types of PLC expansion modules at present. Therefore, this technical problem needs to be solved urgently.

As mentioned above, the hardware control system PLC in the current industrial control system application is generally used to implement simple logic and complete control functions. It is difficult to implement artificial intelligence and adaptive learning algorithms in the future, so the control application scenarios are relatively narrow. In order to solve this technical problem, the embodiment of the present application provides a functionally configurable digital control system for an accelerator, as shown in Figure 1, the functionally configurable digital control system for an accelerator may include a baseboard, a core board and a functional subcard, specifically:

Edge service is a localized service designed to meet the needs of real-time, cost, security and privacy protection. It implements business through local devices without transmitting data to the cloud, thereby improving processing efficiency and reducing the load on the cloud. Edge service inherits the traditional automation control concept and business concept, also known as edge computing, which involves more functions about data computing and processing.

At the same time, it also has new content such as intelligent prediction through cloud-edge collaborative big data processing, or real-time full-chain monitoring and tracking of production data in production, warehousing, logistics and other links.

In this embodiment, the edge service collects and subscribes to the signal variables of the configurable digital control system for the accelerator based on different types of communication protocols, and centrally manages the data and builds models to achieve the description, diagnosis, prediction and decision-making of the operating status of the on-site equipment, and realizes interactive feedback with the configurable digital control system for the accelerator, so as to better complete the operation tasks of the controlled equipment (such as accelerator, etc.). Container technology or virtual machine technology is used to develop various applications to realize complex functions.

Further, two core board interfaces on the baseboard can be selected, referred to as the first core board interface and the second core board interface; the first core board is pluggable and connected to the baseboard through the first core board interface, and the second core board is pluggable and connected to the baseboard through the second core board interface. It should be noted that the examples listed here are only schematic and do not limit the present embodiment.

The present application provides a possible implementation method. The daughter card module interface on the baseboard mentioned above may include one or more, which can meet the needs of different industrial control scenarios. For example, in the industrial control scenario of a mobile phone production line, the following five functions may need to be implemented:

(1) Production line monitoring: Real-time monitoring of equipment status, production quantity, abnormal conditions, etc. on the production line to ensure the smooth progress of the production process.

Logic Unit: This is the basic component of FPGA and is used to perform logical operations.

Programmable Interconnects: These interconnect channels establish connections between logic cells, allowing them to communicate with each other.

Programmable I/O: These interfaces allow the FPGA to communicate with external hardware.

Thanks to the rapid development of the country's high-tech undertakings and basic research, the research on FPGA process technology has also been domestically designed. At the same time, the capabilities of domestic FPGA engineers are getting higher and higher, which has played a significant role in the development of FPGA applications. At the same time, with the rapid development of FPGA chip functions and the development of peripheral hardware chips, some technologies that were previously unthinkable and unrealizable have gradually become a reality. Compared with the traditional programmable control system of PLC, FPGA is a programmable general-purpose chip used to implement complex logic and has a large number of digital I/O pins. And FPGA is used in various fields, because it runs a real digital logic circuit inside, so when the product production scale is small, due to the high one-time cost of dedicated chips, FPGA is often used instead of dedicated chips. In addition, FPGA is also used for functional verification of dedicated chips.

The present application proposes a functionally configurable digital control system for an accelerator, which is based on the high performance and multiple interfaces of FPGA, and is proposed to solve the shortcomings of PLC in current industrial control, broaden the application scope and applicable occasions of industrial digital control, give full play to its technical characteristics in artificial intelligence and algorithms, accelerate industrial development in high sampling rate and high precision application scenarios, provide a new technical choice within the scope of application, and use its own advantages to improve the reliability and maintainability of equipment, and reduce its use cost and time cost.

ARM processors use a Reduced Instruction Set Computer (RISC) architecture. Compared to the Complex Instruction Set Computer (CISC) architecture, its instruction set is more streamlined, allowing the processor to execute instructions faster, with lower power consumption, smaller size and lower cost. ARM processors generally have the following characteristics:

Low power consumption: ARM processors consume very low power, allowing mobile devices to have longer battery life.

High performance: ARM processors have very high performance and can be used in a variety of advanced computing applications.

Low Cost: Since ARM processors are very cheap to manufacture, they are widely used in various mobile devices and embedded systems.

Customizable: ARM offers a variety of different processor architectures and instruction sets that can be customized according to the needs of specific applications.

Support for a wide range of operating systems: ARM processors can support a wide range of operating systems such as Linux, Android, Windows, etc.

In this embodiment, ARM runs embedded software, processes advanced algorithms, controls external devices, communication protocols, etc. It can run real-time operating systems (such as Linux, etc.), provide high-level programming language support (such as C or C++, etc.), provide various data required for upper-level visualization, and run the program to complete the configuration of various functions of the controller.

FPGA provides flexible hardware acceleration and parallel processing capabilities, and can reconfigure and customize circuits according to application requirements. It is mainly used to implement the operation control logic of accelerators and other devices, efficient data processing, parallel computing, acceleration algorithms, etc.

In this embodiment, FPGA and ARM are integrated in the core board, which can not only realize FPGA digital hardware logic, but also carry an onboard system, generally using the Linux system, which builds relevant IOC (Inversion of Control) and can perform corresponding software algorithms, and the software algorithm has also realized modular configurable functions.

A possible implementation method is provided in an embodiment of the present application. The core board may also include: a signal acquisition module, which is connected to the processor, so that the data collected by the signal acquisition module is submitted to the processor for processing.

A possible implementation method is provided in an embodiment of the present application, and the signal acquisition module may include: an analog-to-digital converter (ADC) and a digital-to-analog converter (DAC).

ADC can convert analog signals into digital signals. It achieves analog-to-digital conversion by sampling the analog signals regularly and converting the voltage or current value of each sampling point into the corresponding digital value. During the conversion process, ADC will perform quantization processing inside, that is, converting the continuous analog signal obtained by sampling into a discrete digital signal. Quantization processing is usually carried out with a certain quantization error and resolution. For example, an 8-bit ADC can divide the input voltage range into 256 quantization levels, where each level represents a digital output code. The output of ADC is usually a string of binary digital signals, which can be used in applications such as digital signal processing, data acquisition, and control systems. According to different conversion accuracy, speed, and interface type, there are many different types of ADC, such as parallel ADC, successive approximation ADC, indirect ADC, etc. When choosing to use ADC, it is necessary to select the appropriate type and parameters according to the requirements of the actual application.

DAC can convert digital signals into analog signals. DAC usually contains a digital register, a decoder and a digital-to-analog converter. The digital register receives the input digital signal, the decoder decodes the digital signal into the corresponding analog signal, and the digital-to-analog converter converts the decoded analog signal into an actual analog voltage or current output. According to different conversion accuracy and speed, there are many different types of DAC, such as parallel DAC, serial DAC, voltage DAC and current DAC. Parallel DAC usually has higher accuracy and slower conversion speed, while serial DAC has lower accuracy and faster conversion speed. DAC is widely used in applications such as digital signal processing, audio and video signal output, control system, etc. For example, digital audio players and digital TVs need to convert digital audio signals into analog audio signal outputs, and digital temperature controllers need to convert digital temperature signals into analog temperature control signal outputs.

A possible implementation method is provided in an embodiment of the present application. The base plate mentioned in the above embodiment may also include a switch, a timing interface and an indicator light.

A possible implementation method is provided in an embodiment of the present application. The functionally configurable digital control system for an accelerator shown in FIG1 may further include: a display screen connected to the core board to display data output by the core board.

A possible implementation method is provided in an embodiment of the present application. The core board interface of the baseboard and the daughter card module interface of the baseboard mentioned in the above embodiment are both high-speed connectors.

High-speed connectors usually refer to connectors with a transmission rate of more than 1 Gbps. Common high-speed connectors include 3.5mm connectors, 2.4mm connectors, and 1.85mm connectors. These connectors are usually used in communication and data transmission systems, such as computer networks, servers, switches, routers, etc. Among them, the 3.5mm connector is one of the earliest high-speed connectors. It is larger in size and can accommodate more cables, which is suitable for high-density and high-speed data transmission. The 2.4mm connector is a smaller version of the 3.5mm connector, which is suitable for higher-speed systems and can transmit 60GHz signals. The 1.85mm connector is a smaller version of the 2.4mm connector, which is mainly used for 67GHz and 70GHz signal transmission. The transmission rate of these high-speed connectors can usually reach 10Gbps to 100Gbps, or even higher. They are widely used in the fields of communication and data processing, supporting high-bandwidth, high-speed and long-distance data transmission.

In particular, the core board, baseboard, and daughter card can all be designed with domestic chips to achieve a fully domestically produced digital control system.

Furthermore, the functionally configurable digital control system for the accelerator complies with standardized design specifications, and the pin designs on its core board, base board, and daughter card also support current commercial boards, thereby realizing the combination of commercialization and industrialization.

In particular, due to the diverse needs of industrial control scenarios, a variety of collaborative solutions can be selectively formulated according to project requirements in order to achieve the best control effect.
