Background technology
Along with the development of information technology and the universal of Ethernet, industry-by-industry generally uses Ethernet to carry out information transmission, some requires to transmission speed the information transmission that high industry even uses gigabit Ethernet to carry out between equipment, and these equipment generally all needed to carry out strict testing and emulation before being put into use, be just allowed to use; Generally these equipment are accessed standard measuring signal source respectively by gigabit Ethernet, this standard measuring signal source is made to carry out emulation testing to each equipment respectively, and the gigabit Ethernet of this equipment must be switched to standard measuring signal source when some device emulation tests, the switching mode that general employing is manual at present: first, manually an equipment is accessed standard measuring signal source by gigabit Ethernet, standard signal source is to this testing equipment; Then, the equipment tested is unloaded, more manual by another equipment access standard measuring signal source, carry out the test to second equipment, complete the emulation to all devices and test in this manner.But above-mentioned gigabit Ethernet switching mode needs staff to access each equipment and extract, and operating process is loaded down with trivial details, efficiency is low and greatly waste labour.Except traditional manual mode, also has a kind of switching adopting common relay or analog switch to carry out gigabit ethernet signal, although this mode can realize automatically switching, improve efficiency, but common relay and analog switch belong to the switch of physical equipment, and transmission rate is low, and gigabit Ethernet belongs to high speed signal, thus the switching rate of relay and analog switch cannot meet the rate requirement of gigabit Ethernet; In addition, common relay and analogue quantity switch have electromagnetic induction in handoff procedure, and the generation of these galvanomagnetic effects can affect communication quality, thus cause cannot proper communication.
Summary of the invention
The object of the present invention is to provide a kind of gigabit Ethernet switching device shifter, the gigabit Ethernet that this switching device shifter can automatically realize between different ethernet device and standard measuring signal source switches, and can ensure communication quality.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of gigabit Ethernet switching device shifter, comprise MCU module, the input interface of MCU module connects computer, and output interface connects gigabit Ethernet switch chip TS3L500AE, and the switching command that computer sends by MCU module sends to gigabit Ethernet switch chip TS3L500AE; The input channel of gigabit Ethernet switch chip TS3L500AE connects one group of ethernet device respectively, output channel connection standard signal testing source.
Further, described MCU module is connected with the toggle switch for arranging MCU module node address.
Further, described MCU module is connected with the LED charactron for showing MCU module node address.
Further, described gigabit Ethernet switch chip TS3L500AE is connected with the status indicator lamp for display channel state.
The invention has the beneficial effects as follows, adopt the switching command that gigabit Ethernet switch chip TS3L500AE receiving computer sends, the ethernet device that need switch is switched on corresponding passage, and then makes this ethernet device set up Ethernet with standard signal test source to be connected; This switching device shifter structure is simple, and the gigabit Ethernet that can realize rapidly between different ethernet device and standard measuring signal source switches, and avoids the electromagnetic induction that common relay and analogue quantity switch produce in handoff procedure, ensures communication quality.
