FPGA-based wireless transmission delay control system and control method

Abstract

The invention discloses an FPGA-based wireless transmission delay control system and method. The system comprises a wireless module, an FPGA processing module and a user interface module, wherein the wireless module is connected with the FPGA processing module through an SPI or a UART serial communication interface; the FPGA processing module is connected with the user interface module through a PSI or a UART serial communication interface; the user interface module is connected with an upper computer which controls the wireless module and the FPGA processing module. First-level wireless transmission management is added, so the system can record and manage transmission delay in the wireless transmission process and achieve transparent transmission by means of protocol analysis to facilitate addition to an existing system; moreover, a master station and a slave station can build a real-time communication wireless network just by means of setting software through a general module, so the defect that existing technology cannot adapt to system change is overcome; the system has the advantages of being simple in structure, reliable in operation, high in applicability and the like.

Description

technical field [0001] The invention relates to the technical field of industrial real-time control, in particular to an FPGA-based wireless transmission delay control system and control method. Background technique [0002] With the advent of the Industry 4.0 era, the complexity of automation packages continues to increase. In the production and manufacture of mechanical automation equipment, it is faced with the design requirements of miniaturization, integration and generalization. The assembly and commissioning of equipment on the traditional industrial site has been difficult to meet the needs of the market. More and more miniaturized devices use more flexible wireless communication methods for information interconnection, such as ZigBee, wifi, etc. However, since the wireless network uses a common channel frequency, the bandwidth occupation problem in the channel leads to the uncertainty of transmission delay in wireless network communication compared with traditiona...

AI Technical Summary

Problems solved by technology

However, due to the use of public channel frequencies in wireless networks, the bandwidth occupation problem in the channel leads to the uncertainty of transmission delay in wireless network communication compared with traditional wired transmission.

This makes wireless transmission unable to be widely and effectively applied in some occasions that require real-time control, precise compensation, and fast system response.
