Problems solved by technology

[0002] At present, in environmental protection, electric power, industrial control, security and other industries, a large number of computer systems are used, and Ethernet is widely deployed for computer networking. Therefore, Ethernet has become a common interface method in the existing environment, but a large number of Electronic equipment and instruments are designed to communicate only through the RS232 serial port. When the electronic equipment and instruments are not in the same place as the control computer, it is necessary to use a way to network the electronic equipment and instruments with the computer. Usually, the method of extending the serial line (such as RS484 communication) is used. This method generally has the problems of heavy wiring workload and difficult implementation, and the extension distance is also limited.

Abstract

The invention discloses an embedded serial port networked server, mainly comprising an Ethernet PHY and an Ethernet interface connected with the Ethernet PHY, and also comprising a CPU and a power processing module, a UART interface and an I/O port, an EEPROM memory and an SRAM memory, which are respectively connected with the CPU; wherein, the Ethernet PHY is connected with the CPU and the power processing module respectively; the power processing module is also provided with a power interface and a watchdog circuit which is directly connected with the CPU. The server can substantially simplify user equipment and realize SMS transceiving, is convenient and reliable in use and has universality.

Description

technical field [0001] The invention relates to a server, in particular to an embedded serial port networking server. Background technique [0002] At present, in environmental protection, electric power, industrial control, security and other industries, a large number of computer systems are used, and Ethernet is widely deployed for computer networking. Therefore, Ethernet has become a common interface method in the existing environment, but a large number of Electronic equipment and instruments are designed to communicate only through the RS232 serial port. When the electronic equipment and instruments are not in the same place as the control computer, it is necessary to use a way to network the electronic equipment and instruments with the computer. Usually, the method of extending the serial line (such as RS484 communication) is adopted. This method generally has the problems of heavy wiring workload and difficult implementation, and the extension distance is also limit...
