Description

Integrated network exchanges and supports the serial server that poe powers

Technical field

The utility model is related to a kind of serial server and in particular to a kind of integrated network exchanges and supports what poe powered Serial server.

Background technology

With scientific and technological development, serial communication is all widely used in different industries, at this stage, serial server function Also more single, simply rs 232 serial interface signal and network signal are changed, function is more single, network interface also only one of which, multiple Serial server application needs external switch, and each serial server need to connect a power line, netting twine, one Serial Port Line, is so not only inconvenient to use, also inconvenient daily equipment control.

Content of the invention

Technical problem: the technical problems to be solved in the utility model is, the shortcoming overcoming prior art, propose a kind of integrated Network exchange simultaneously supports the serial server that poe powers.

Technical scheme: the integrated network that the utility model provides exchanges and support the serial server that poe powers, including friendship Change planes module, power module, network interface module, serial port module and processor；Described power module include DC power-supply circuit and Poe power supply circuits；Described DC power-supply circuit is that described switch module, network interface module, serial port module and processor are powered；Institute State network interface module and pass through the described switch module described processor of connection；Described serial port module connects described processor；Described net Mouthful module has two network ports, and one of network port and described poe moding circuit of powering is connected by wire jumper.

Such scheme is further improved by: described serial port module includes rs232 serial port circuit.

Such scheme is further improved by: also includes being connected to the power supply indicator of described power module, is connected to The serial ports indicator lamp of described serial port module and the network port indicator being connected to described switch module.

Such scheme is further improved by: has hy602401 network transformer in described network interface module.

Such scheme is further improved by: has fuse, anti-reverse diode in described power module.

Beneficial effect: the integrated network that the utility model provides exchanges and support the serial server that poe powers, and has two The individual network port, by switch module, the network port can be used for connecting field network equipment or multiple serial server tandem Networking is it is not necessary to the external network switch is it is achieved that the centralized management of the multiple stage network equipment.One of port supports that poe supplies Electricity input or export, and then make field network equipment maintenance work simpler.

Except the utility model recited above solve technical problem, constitute technical scheme technical characteristic and by this Outside the advantage that the technical characteristic of a little technical schemes is brought, integrated network of the present utility model exchanges and supports the string that poe powers The other technical characteristics comprising in other technologies problem that mouthful server can solve, technical scheme and these technical characteristic bands The advantage come, will combine accompanying drawing and be described in more detail

Specific embodiment

Embodiment

The integrated network that the present embodiment provides exchanges and supports the serial server that poe powers as shown in figure 1, including exchanging Machine module 2, power module 3, network interface module 4, serial port module 5 and processor 1.

Wherein, the circuit diagram of processor 1 and switch module 2 is as shown in Fig. 2 adopt rtl8305 conduct in the present embodiment Processor, meanwhile, this ic is also integrated with switch function, therefore, is extremely suitable for this programme.As figure, only show its each pin net Network label, and crystal oscillator, reset circuit etc. are well known to those skilled in the art, therefore and be not drawn into.

The circuit diagram of power module 3, as shown in figure 3, converting ic using lm2589s as dc-dc, carries for whole server For direct current 3.3v, meanwhile, by voltage-stabiliser tube d5, provide poe power supply.It is outer that binding post j1 connection is passed through in the front end of power module 3 Portion's power supply, is then provided with fuse, anti-reverse diode etc., to realize the functions such as anti-reverse, Anti-surging and overcurrent protection.

Serial port module 5 circuit diagram is as shown in figure 4, the present embodiment adopts st3232ectr chip and its peripheral circuit group bunchiness Mouth module 5, interface then adopts db9 interface.Tx1 the and rx1 pin of serial port module 5, after level conversion ic, reconnects 14 to 17 pins of rtl8305, level conversion ic adopts usr-tcp232-s, and rs232 level conversion is rj45 interface level, This ic and its peripheral circuit are well known to those skilled in the art, and therefore omit this figure.

As shown in figure 5, the present embodiment provides two network port j4 and j2, wherein j4 connects poe electricity by wire jumper jp1 Source, two ports are respectively connected with hy602401 network transformer；The wherein data pin 13,14,16,17 of j4 is divided according to network number Not Lian Jie rtl8305 9 to 12 pins；The data pin of j2 19,20,22,23 connects 1 to 4 pin respectively.

Power module 3 is connected with the serial ports indicator lamp of power supply indicator, serial port module 5, and switch module 2 is connected with network interface Indicator lamp.It is well known to those skilled in the art using indicator lamp, therefore in figure is not illustrated.

All elements are installed on same circuit board, and, circuit board is closed in One function box, only respectively patches Part, wire jumper and interface expose.

The serial server of the present embodiment so constituting has following function, network interface j4 and j2, and serial ports db9 is as needed Field equipment connecting, because rtl8305 itself possesses switch function, it is thereby achieved that the centralized management of the multiple stage network equipment. Need also dependent on scene, the serial server that arrangement multiple stage the present embodiment provides, carry out tandem networking, then can easily expand The amount of making up the number, manages more equipment simultaneously.

Network interface j4 has poe power supply capacity, can conveniently carry out opening/close poe using wire jumper jp1 and power.Conversely, working as There is no binding post j1 and power in environment, also can by network interface j4 from extraneous poe power taking power for this serial server. The employing of hy602401 network transformer, then ensure that the network port is adapted to the network equipment of multiple varying levels, prevent not Pass through network cable transmission damage equipment with voltage.

Above in association with accompanying drawing, embodiment of the present utility model is described in detail, but the utility model is not limited to institute The embodiment of description.For those of ordinary skill in the art, in the scope of principle of the present utility model and technological thought Interior, multiple changes, modification, replacement and deformation are carried out to these embodiments and still falls within protection domain of the present utility model.
