Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention.
Fig. 1 is a schematic block diagram of an embodiment of the present invention.
Fig. 2 is a schematic application diagram of an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
A server watchdog system based on network interface monitoring technology comprises a host, a network interface chip, an RJ45 network interface, a photoelectric isolation device and a reset interface; the host comprises a singlechip, a liquid crystal panel and a control key, and the control key and the liquid crystal panel are matched for inputting an IP address to the singlechip; the single chip microcomputer is connected with the input end of an RJ45 network interface through a network interface chip, and the output end of an RJ45 network interface is connected with a data network interface of the server; the singlechip is connected with the input end of the reset interface through the photoelectric isolation device, and the output end of the reset interface is connected with the reset interface of the server mainboard.
In this embodiment, the output end of the RJ45 network interface is connected to the data network interface of the server through the switch.
In this embodiment, the single chip and the network interface chip communicate with each other through a UART or SPI bus.
In this embodiment, the network interface chip is a CH395 chip.
The utility model discloses can be directly through net twine connection server, also can be connected to the network interface of server through the network switch is indirect.
After the system is powered on through a power supply interface, an ECHO _ REQUEST data packet based on an ICMP (network control message) protocol is periodically (for example, once every 10 seconds) sent to a server through a CH395 network interface chip and an RJ45 network interface based on an IP address stored in a FLASH memory in a single chip microcomputer, whether the server gives a reply or not is detected, if the reply is not given for a plurality of times continuously, the hardware or the operating system of the server is judged to have a fault, and a reset signal is sent to restart the server through a photoelectric isolation device and a reset interface.
The data packet responding to the ECHO REQUEST is the self-contained function of the server operating system, and is equivalent to the network function of the server tested by using the ping instruction, so that other software does not need to be loaded on the server.
When the sending of the reset signal is just completed or the system is just powered on, a period of time (e.g. 2 minutes) is waited to ensure that the server has completed the boot process, and the ECHO _ REQUEST packet can be replied to start sending the packet periodically to monitor the operating status of the server.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
