Network communication guarantee device

Abstract

The communication guarantee device relates to a network communication device. The communication guarantee device is installed next to the network device and connected to the network through a network cable, and includes an alarm module, a storage module, a serial port communication module, a power supply circuit, a network module, an MCU part, and The external power supply control module is composed. The network port of the communication guarantee device, the relay output port, and the power input port; the relay output port is connected to the power line of the network device, and the control relay output terminal is connected to the power supply; the IO port of the chip computer is connected to the relay and the power supply. The invention is installed next to the device whose network communication needs to be guaranteed, so that it can discover the communication problem of the network device and control its restart to solve the communication failure of the network device. If it still fails to communicate normally after multiple restarts, it will send out an audible and visual alarm signal and record related events.

Description

technical field [0001] The invention relates to a network communication device, in particular to a network communication guarantee device. Background technique [0002] At present, network devices are becoming more and more popular, including switches, routers, wireless APs, broadband modems, network cameras, etc., and there are many brands with varying quality. However, the network products used in general households cannot guarantee that they can communicate normally all the time. They often fail to communicate after running for a period of time, and the devices in this situation generally do not automatically return to normal. It is often necessary to manually restart the device before returning to normal work. Manually restarting the network device is not only time-consuming and laborious, but also unable to find problems in time, especially the unattended network monitoring device. Therefore, a device capable of discovering network communication faults in time and rec...
