Description
Technical field
This utility model belongs to technical field of network equipment, it particularly relates to a kind of switch being provided with stand-by power supply.
Background technology
Switch is a kind of network equipment forwarded for electricity (light) signal, and it can be that any two network node of access switch provides the pathway for electrical signals exclusively enjoyed.Modal switch is Ethernet switch.Industrial switch is also referred to as industrial ethernet switch, i.e. it is applied to the Ethernet exchanging machine equipment of industrial control field, due to the network standard used, its opening is good, be widely used and cheap, use transparent and unified ICP/IP protocol, Ethernet has become as the Primary communication standard of industrial control field.Industrial ethernet switch uses storage conversion exchanged form, improves ethernet communication speed, and built-in intelligence alarm design monitoring network operation conditions so that ensure, in severe dangerous industrial environment, the operation that Ethernet is reliable and stable simultaneously.Its product line is enriched, and port flexible configuration can meet the use demand of various industrial circle.
Along with network setting ON TRAINS, the research of vehicle-mounted industrial switch gets more and more.In rail traffic vehicles running, powersupply system noise is obvious, voltage pulsation is bigger, therefore, its often cannot the supply voltage of outputting high quality, and in prior art, the power circuit of Ethernet switch to the power supply of above-mentioned instability without processing function, therefore the requirement of rail vehicle power environment cannot be met so that on vehicle, the quality of communication can not be guaranteed.
Summary of the invention
The purpose of this utility model is to provide a kind of switch being provided with stand-by power supply, to solve the drawbacks described above of existence of the prior art.
In order to realize the purpose of this utility model, the utility model discloses a kind of switch being provided with stand-by power supply, described switch includes exchanging rack and switch body, described exchange rack includes cabinet and cabinet door, it is provided with column in described cabinet, the gripper shoe placed for switch body it is provided with between column, cabinet is provided with winding displacement groove, the top of cabinet is provided with air draft mechanism, the bottom of cabinet is provided with adjustable for height grounding assembly, mobile roller and adjustable for height braking mechanism, the rear wall of cabinet is provided with louvre, described switch body includes body casing, mainboard, network terminal interface, LED light and power interface；Described network terminal interface is located at directly over body casing；Described LED light is located at the front of network terminal interface, and both positions are corresponding to number；Described power interface is located at the lower section of body casing；Described mainboard includes DC/DC conversion module, rechargeable battery, CPU and the Ethernet switching chip being sequentially connected with；Described network terminal interface is connected with Ethernet switching chip；Described LED light is connected with motherboard circuit；Described power interface is connected with DC/DC conversion module.
Wherein, described air draft mechanism includes the cover plate being fixedly connected on cabinet and arranges exhaust fan on the cover board, and cover plate is provided with dust cover.
This utility model, compared with prior art, has rechargeable battery so that when outer power voltage moment disconnects, thus still can provide stable output voltage, meet the use demand of client.
