Description

Serial server
Technical field
Server field is the utility model is related to, more particularly to a kind of serial server.
Background technology
With the fast development of computer, communication and network technology, extensive use of the wireless communication technology in different industries Turn into one of focus.The application of wireless communication technology be not confined to the environment of traditional commercial office complex, and progressively Enter in large-scale colliery and oil field, industrial automation, data acquisition and monitoring system every field and environment.
Case becomes the core that comprehensive control device is Power Station Monitored Control System, realizes intelligent management.Case becomes comprehensive control Device can become to wind-powered electricity generation, photovoltaic case to be protected and remote monitoring, thus it is distant to run into communication transmission distance, existing Serial communication can not meet the problem of communication need, it is necessary to by ethernet communication incoming fiber optic interchanger, realize the long distance of equipment From monitoring.The function of serial server is single at present, and monitoring effect is poor.
Therefore need badly and provide a kind of new serial server to solve the above problems.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of serial server, and case can be become to comprehensive control dress The serial communication put is converted to ethernet communication.
In order to solve the above technical problems, the technical scheme that the utility model uses is:A kind of serial server is provided, Including MCU, serial network controller, network transformer, RJ45 network interfaces socket, serial port module, the non-volatile sudden strain of a muscle being connected with MCU Deposit, dynamic RAM, electrical level transferring chip;MCU, serial network controller, network transformer, RJ45 network interfaces socket are successively Be connected, serial port module is connected with the output end of electrical level transferring chip, serial network controller be additionally provided with network data indicator lamp, Network connection status indicator lamp.
In one preferred embodiment of the utility model, MCU is provided with Ethernet interface, and serial network controller passes through ether Network interface is connected with MCU.
Further, Ethernet interface includes electric Ethernet interface, luminiferous ether network interface, is applicable not only to the serial server Wind-power box becomes measure and control device, and is also applied for photovoltaic case and becomes measure and control device.
In one preferred embodiment of the utility model, serial port module includes RS232 serial ports, RS485 serial ports, RS232 strings Mouth uses DB9 needle sockets.
The beneficial effects of the utility model are:The utility model stable and reliable operation, case can be become comprehensive control device Serial communication be converted to ethernet communication, its serial network controller possesses the abnormal function of initiative recognition connection, Neng Gouzhong Auto-reconnect after connection breaking, realize stable remote-wireless communication.
Brief description of the drawings
Fig. 1 is the structured flowchart of the preferred embodiment of the utility model serial server one;
Fig. 2 is the circuit block diagram of the serial server.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model Define.
Referring to Fig. 1, the utility model embodiment includes:
A kind of serial server, including MCU, serial network controller, network transformer, RJ45 network interfaces socket, serial ports mould Block, the non-volatile flash memory being connected with MCU, dynamic RAM, electrical level transferring chip.MCU, serial network controller, net Network transformer, RJ45 network interface sockets are sequentially connected, and MCU is provided with Ethernet interface, serial network controller by Ethernet interface with MCU is connected, and Ethernet interface includes electric Ethernet interface, luminiferous ether network interface, the serial server is applicable not only to wind-power box change Measure and control device, and be also applied for photovoltaic case and become measure and control device.Serial port module is connected with the output end of electrical level transferring chip, serial ports Module includes RS232 serial ports, RS485 serial ports, it is preferred that RS232 serial ports uses DB9 needle sockets.Serial network controller is also set It is equipped with network connection status indicator lamp LED1, network data indicator lamp LED2.
With reference to Fig. 2, MCU uses the master controller using ARM920T as kernel, and model S3C2440, coupled is non-easy The property lost flash memory can ensure that data are not lost under power-down conditions, the model MAX3232 of electrical level transferring chip, MCU be provided 5V voltage conversions are that 3.3V voltages use for serial port module, serial network controller.MCU data receiver port RXD, data hair Sending end mouth TXD, grounding ports GND respectively the data sending terminal mouth TXD with serial network controller, data receiver port RXD, connect Ground port GND is connected.MCU Data ports connection network data indicator lamp LED2, for indicating the transmission state of network data, Link ports connect network connection status indicator lamp LED1, for indicating network connection situation.The MCU possesses initiative recognition company Abnormal function is connect, after foundation is connected, is had with the KeepAlive keep-alive probe packets of about 15s interval transmission, if even It situations such as being connected to abnormal interrupt, then can be immediately detected, and control the serial network controller to disconnect original connection simultaneously Reconnection.The serial network controller output port connection network transformer, avoid outside netting twine directly with serial network control Device processed is connected, and prevents magnetic induction or electrostatic etc. from causing to damage to controller.Output port RX+ (the reception signals of network transformer +), RX- (reception signal -), TX+ (send signal+), TX- (sending signal -) be connected with RJ45 network interface sockets.
The utility model stable and reliable operation, the serial communication that case can be become to comprehensive control device are converted to ether Netcom News, its serial network controller possess the abnormal function of initiative recognition connection, can in Auto-reconnect after connection breaking, realize stable Remote-wireless communication.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
