Abstract
After power on, server sends command of switching channel to switch to the host. Then, two communication servers communicate to each other. Host connected to the main channel sends message of operation condition of main channel to spare computer connected to the spare channel. While receiving message of abnormal operation of main channel or not receiving message from host for many times, the spare computer considers that the main channel is abnormal, and sends command for switching to spare channel in the spare computer. Using software to implement switching criterion, the method defines switching condition smartly to suit different switching conditions. Through modifying parameters, the method can realize switch between main and spare channels. Switching channels can be carried out between digital channels, analog channels and Ethernet channels.

Technical field
The present invention relates in the integrated automation of transformation stations motion technology transmission system with dispatching communication, the invention provides the switching device shifter that the single, double passage of a kind of telemechanical communication server is cut two-shipper more precisely.Reliability so that this raising information transmits belongs to electric power system communication technical field.
Background technology
Along with the development of electric substation automation system technology,, seem more and more important with the reliability of dispatching communication particularly the promoting the use of of the unattended station of the above grade of 220kV.For four distant (remote measurement, remote signalling, remote control, distant arteries and veins) real time data transformer station is more reliably delivered to remote dispatching, the user of electric power system now mostly requires transformer station's end to realize that automatically the two-shipper of single, double passage switches.The passage here can comprise ethernet channel, and this requirement has become hard regulations and parameters on the tender of a lot of mega projects at present.Such as in Jiangsu, areas such as Guangdong, Shanxi have all explicitly called for and have realized this function.Existing traditional switching device shifter switches the too high and configuration setting of cost and gets up very dumb.Traditional switching device shifter can only simply switch the serial ports passage, switch for ethernet channel and do not realize, and have only externally channel abnormal just can judge to switch and stand in can not judge switching unusually.Also can't many conditions that passage switches be set in addition according to on-site actual situations.For example all will lead to the IEC104 stipulations in the above transformer station of Shanxi Province 220kV, and IP address of a Shanxi Province scheduling dispensing requires to cut two-shipper, this situation can only could realize this function with this switching device shifter at present.To go up the two-shipper handoff functionality after also having some transformer stations that put into operation to put into operation, because field device has been organized screen and if feeder apparatus perforate installation on screen is all very inconvenient again owing to be subjected to the place restriction, at this moment use this novel switching device shifter just easily, for example come to this and realize the two-shipper handoff functionality after putting into operation easily again in Lanzhou Ma Quan change.
Summary of the invention
The technical problem to be solved in the present invention is: at the problem that above prior art exists, propose a kind ofly to realize that single, double passage cuts the novel switching device shifter of the fast server of bilateral.
In order to solve above technical problem, the present invention takes following technical scheme to realize:
Switch at communication server two-shipper, mainly set about two aspects: consider with software on the one hand from judging by communication server inside whether PERCOM peripheral communication and intercommunication be unusual, the Rule of judgment of two-shipper switching is just more reasonable like this, and can be provided with switching conditions such as the error rate as parameter.When second aspect is cut two-shipper when single channel; adding the passage switch card again when judging with software switches; this jig has independently power supply; when switching; measure and control device receives the pulse signal that produces behind the guidance command and starts the actuating of relay on the switch card and reach the physical connection of cutting off unusual machine and the physical connection of connecting normal machine in standing; this card structure adopts plug-in unit, and still to cut ethernet channel all be a kind of general switching plug-in unit no matter cut digital channel or cut analog channel.This plug-in unit can have on the device cabinet of dead slot at other arbitrarily to be inserted.If cutting two-shipper, binary channels then need not this switch card.
The New-type switching method of tele mechanical host-standby communication comprises main frame, main channel, standby host and is equipped with passage that it is characterized in that: described main frame connects the main channel, and standby host connects passage fully, and active and standby machine connects by network in the station.The host-standby communication server is issued the offside machine by the communication of network in standing with the communication conditions message of this machine, and (annotate: being called for short this machine when narrating a certain the communication server is this machine, and another then abbreviates the offside machine as.) do not receive the message of sending and think that then this machine unusually then sends out switching command and cut to the offside machine when the offside machine receives the message of the passage operation exception of sending or continuous several times.
The New-type switching method of aforesaid tele mechanical host-standby communication is characterized in that wherein said machine can be that channel abnormal also can be that communication server station communication is unusual unusually.
The New-type switching method of aforesaid telemechanical communication, the condition that it is characterized in that wherein said switching command be external channel can not receive message time, the number of times of receiving error code or station in time of communication abnormality.Because transfer criterion realizes with software, thus its switching condition just can define flexibly, as: external channel can not receive the time of message, receives the number of times of error code, stands the time of interior communication abnormality etc.Different regions require not simultaneously switching condition, have related parameter can satisfy requirements of different users as long as revise.
The New-type switching method of aforesaid tele mechanical host-standby communication is characterized in that wherein also being added with between the active and standby machine passage switch card when single channel is cut two-shipper.
Handover mechanism of the present invention is: check earlier after two communication servers power on whether this machine is set at main frame, if when being made as main frame and being the binary channels Dual OMU Servers Mode again then directly and a distant place connect, if then send out during the single channel Dual OMU Servers Mode switching command by the passage switch card this single channel cut to connect with a distant place again after main frame is connected.Main frame sends to standby host to communications status and receives the communications status of standby host then.If be not that main frame is standby host then does not connect with a distant place after the power on of front, then send out the communications status of standby host and receive the message of the channel status that main frame sends.Do not receive the message that main frame sends and think that then main-machine communication is unusual when standby host receives the message of host channel operation exception or continuous several times, this moment if the binary channels Dual OMU Servers Mode then standby host directly connect with a distant place, by the passage switch card this single channel is cut to the standby host connection and is connected with a distant place again if then send out switching command during the single channel Dual OMU Servers Mode.Then the communications status of this machine is sent to the offside machine, and receive the communications status of offside machine.Vice versa is so cut to main frame by standby host.In this novel switching device shifter because transfer criterion realizes with software, so its switching condition just can define flexibly, as: external channel can not receive the time of message, receives the number of times of error code, stands the time of interior communication abnormality etc.Different regions require not simultaneously switching condition, have related parameter can satisfy requirements of different users as long as revise.
In telemechanical communication server main task, to create an independently thread, this thread is mainly finished two functions, one is to judge whether this machine passage is normal, another is to communicate by network in standing and offside machine, the communications status of this machine is issued the offside machine, and receive the signal intelligence of offside machine.This thread normally operates in the endless loop as accompanying drawing one, each represents the channel status of corresponding each teletransmission with the size of the count variable value of an overall situation, this variable Δ t at set intervals just increases a constant 1, if transmitting-receiving normally just deducts this variable a constant 2 in using the stipulations program, make mistakes as the effect sign indicating number when communication is undesired, station communication is unusual just with constant 3 of this variable increase, thinks this channel abnormal when this variable is increased to 4 of certain threshold value constants.More than said Δ t and constant 1,2,3,4... all can parametric form look different occasions and be provided with different.
The main feature of this product: this novel switching device shifter can be realized the switching between the active and standby machine, and the perhaps switching between the primary channel, switching can be between the digital channel, between the analog channel, between the ethernet channel.Can accomplish with this handoff technique:
1) switching between the digital channel
2) switching between the analog channel
3) switching between the Ethernet
4) switch with the mixing between the upper channel
5) orientability of switching condition
6) passage is normal, but communication server can judge switching unusually
