Serial server

Abstract

The invention discloses a serial server. The serial server comprises a serial module, a magnetic decoupling isolation circuit, an interface circuit, a first power supply circuit and a second power supply circuit, wherein the magnetic decoupling isolation circuit is arranged between the serial module and the interface circuit to realize isolation of signals; the first power supply circuit is connected to the interface circuit and the magnetic decoupling isolation circuit in order to supply power to the interface circuit and the magnetic decoupling isolation circuit; and the second power supply circuit is connected to the serial module, and is used for supplying power to the serial module. Through adoption of the serial server, the problem that an existing serial server is interfered easily by extreme weathers such as external lightning is solved, and the interference resistance of the serial server is enhanced.

Description

technical field

[0001] The invention relates to the field of communication signal transmission, in particular to a serial port server. Background technique

[0002] In recent years, with the development of science and technology, the construction of automatic weather stations has made great achievements. Although the meteorological observation business and meteorological service fields of automatic weather stations have been widely used, there are still some shortcomings. As electronic equipment, since most of the collectors and other equipment are in the wild environment, they are prone to interference from extreme weather such as external lightning, and data acquisition and transmission equipment such as communication management machines in the traditional sense cannot meet the environmental requirements. Contents of the invention

[0003] The object of the present invention is to provide a serial port server, which overcomes the problem that the existing serial port se...
