Problems solved by technology

However, the design and implementation method of general embedded system Ethernet serial port server is relatively complicated. Its physical layer and data link layer are implemented by chip hardware, and other layers are implemented by software. In embedded systems, RAM space is limited, and TCP / The IP protocol stack is very limited, and the porting work is more complicated

Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0024] Such as figure 1 As shown, a multi-type serial port-to-Ethernet server introduces the new Ethernet solution of the Ethernet chip W5500. Using hardware TCP / IP technology, design an industrial serial port server to realize the conversion function of single-chip serial port protocol and TCP / IP protocol, that is, the communication between the serial port server and the upper computer adopts USART or SPI protocol. The hardware of the serial port server in this design is based on the STM32F103 control chip and W5500 chip, and the software is based on the Keil uVision5 development and compilation environment. The core chip Ethernet W5500 chip integrates the TCP / IP protocol stack, that is, the chip itself integrates the relevant protocols of the network layer and the transport layer. In terms of software design, it only needs to initialize and configure the parameter...

Abstract

The invention relates to a server for converting multiple types of serial ports into Ethernet, which introduces a new Ethernet solution of an Ethernet chip W5500. A hardware TCP / IP technology is utilized to design an industrial serial port server, and a single-chip microcomputer serial port protocol and TCP / IP protocol conversion function is realized. The serial port to industrial Ethernet server has the advantages of high industrial communication real-time performance, high reliability, high safety and the like, has the characteristics of low cost, low energy, high fault tolerance and the like, and can meet the requirements of application real-time performance, reliability and safety of an industrial sensor data level; and the server has great advantages in the aspect of improving the network performance of existing sensor data, can replace a traditional communication network, and has a good application prospect.

Description

technical field [0001] The invention relates to a multi-type serial port-to-Ethernet server and a control method. Background technique [0002] Since the beginning of the 21st century, network intelligence has entered thousands of households and has become an indispensable part of people's lives. Intelligent industrial products have gradually become popular, such as welding robots and rehabilitation medical robots. But so far, it has only been applied locally, and large-scale intelligent applications are still in the initial stage, such as the monitoring and security systems of chemical industry parks. Due to the outdated technology, disasters and accidents frequently occur. However, once a leak occurs in the chemical and hazardous chemical industry, it is usually accompanied by the risk of fire and explosion. Since the specific situation of the disaster area cannot be obtained immediately, rescuers dare not rush there, delaying the best time to fight the fire. Coupled with...
