Embodiment one
The method of setting up power system monitor disaster back-up system of present embodiment as shown in Figure 1, wherein, two covers are connected with subordinate transformer station, strange land computer network management system that can independent operating is respectively existing regional dispatch automation system (EMS system) and newly-built transformer station's centralized control system (SCADA system).Two systems pass through network supervisor (dnet) separately, can realize data sync and shared in native system, and its hardware is by constituting with the lower part:
The advance data collecting unit---receive each subordinate transformer station information in order to real-time collection, and be transferred to front server;
Front server---with advance data collecting unit signal transmitted treatment conversion is to be transported to the native system database server behind the engineering information;
Active and standby two sets of data storehouse servers (following main frame, the standby host of being called for short again)---the engineering information in order to storage native system preprocessor is carried backups each other, and query and search externally is provided;
Work station---in order to native system is operated control;
System switch---connect in order to realize the network between the native system computer, and front server is connected with network between the advance data collecting unit information;
Bridge and router---realize the physical connection of EMS system and SCADA system in order to the conversion of realization photosignal, by optical cable;
Two systems are carried out the initialization (referring to Fig. 2) of following content:
1. read the configuration file of descriptive system connected mode, wherein defined the connected mode of system, notifying program need to which system forwards data, to realize synchronously and to share;
2. read the configuration file of describing the kind that E-Packets, wherein defined message from which sender and will be forwarded in the other system and go, will not be forwarded in the other system from the sender's who in this configuration file, does not define message;
3.socket initialization to operating system application socket, and is done corresponding setting, sets up network path.
Afterwards, main database server is transferred to each computer of native system with changed information, simultaneously after the model data change operation of accepting work station
---as send server,, carry out data communication by the corresponding with service device in router and the other system, the implementation model data synchronization according to following steps:
1), be that purpose sends, the model changed information is formed real-time packet, with the NIC address of other system corresponding with service device at scheduled time slot;
2), after other system corresponding with service device receives, should feed back response message, as not receiving response message in the given time, the local message file of target when then this send server saves as band in chronological order with real-time packet;
2) ', the described database server that is equipped with constantly duplicates local message, and send local message to master server and duplicate the sign that finishes;
3), whether the main database server test exists local message, be equipped with database server and whether send local message and duplicate the sign of finishing as existing then to detect, as denying, then main database server waits for that this sign arrives, treat next period, NIC address with the other system corresponding server is a purpose, presses the time sequencing that message forms, and sends local message one by one;
4), after other system corresponding with service device receives, should feed back response message, as not receiving response message pre-in regularly, then this database server suspends and sends, and treats next period, continues to send to go up the local message of bar;
5), in step 3)-4) process in, form new real-time packet as this database server, then it is saved as in chronological order the local message file of when band target;
6), as the test result of step 3) for not existing, then go to step 1);
---as reception server, realize data communication by the corresponding with service device in network router and the other system according to following steps:
1), receive the message that other system corresponding with service device sends after, the feedback response message;
2), according to the model database on the message update service device that receives, and other work stations of broadcast announcement upgrade its this machine real-time data base;
Front server is an engineering information with each subordinate transformer station information translation of gathering in real time under normal circumstances, is transported to the native system database server; Under the situation that the one or more transformer stations of this side system message pick-up interrupts, system will receive the real time information of this transformer station of opposite side system forwards automatically by router, thereby will realize that real time information is standby each other.
Need to prove, the socket communication modes is adopted in above communication, mainly comprises two parts, and one is responsible for sending (transys_send), it two be responsible for to receive (transys_recv), and resides in respectively on the main frame of transmitting system main frame and receiving system (referring to Fig. 2).Mainly contain two lines in the process, one is the transmission of real-time packet, and one is the transmission of the local message of preserving.
In brief, most important transmission principle is to send according to sequential, and promptly message sends to other system in strict accordance with the order that receives, with the consistency that guarantees to upgrade.Its logic is as follows:
1. when sending message, be transmit leg, send according to this, send successfully up to receiving correct response message, then thinking to every NIC address to the main frame of side system with this machine (must be main database server).
2. if because network is obstructed, or mechanical disorder, or the corresponding process of recipient is not activated, or do not receive correct replying, and cause message correctly to send to side system, then message will be preserved with the local file of markers as filename.
3. server constantly sends local message to master server and transmits (the pointing to master server duplicates) sign that finishes fully, to tell master server, the local message that does not have preservation.
4. if there is local message not send as yet, the real-time packet that then receives does not send, and is same local by preserving as filename with markers, sequences to be sent such as adding;
5. do not duplicate the sign of finishing if receive the local message that server is fully sent, master server does not send, and arrives up to this sign.(only be set under " unit " mode, just ignoring and whether receive and send this sign to other system.)
6. the transmission of local message is according to time sequencing, if at first one does not send successfully, then transmission stops, and waits for next time and attempting.
With the relevant language description for preparing a computer program, then the present embodiment particular content is:
A, transmission process main frame are: initialization and major cycle.
A1, initialization mainly comprise:
1, reads the configuration file (connect_system. sys) of descriptive system connected mode.Wherein defined the connected mode of system, with notifying program, need to which system forwards data, to realize synchronously and to share.
2, read the configuration file (transys_reptype.sys) of describing the kind that E-Packets.Wherein having defined message from which sender will be forwarded in the other system and go.Message from undefined sender will not be forwarded in the other system.
3, socket initialization to operating system application socket, and is done corresponding setting, sets up network path.
A2, major cycle have according to the order of carrying out in the circulation:
(1.open_log): open journal file, prepare to write as daily record:;
(2.am_i_host): check whether oneself is main frame;
Whether (3.check_local_report): checking has the message that is kept at this locality to need to send;
4. as being not main frame, then the closing journal file restarts circulation;
Whether (5.dnet_receive_message): checking has new message to arrive; (the message here is meant from the program of open2000 and sends over, and need be forwarded to the packet of other system, and its transmit leg is the intrinsic program of open2000, as modify_table etc.)
6. as there not being new message, then the closing journal file restarts circulation;
(7.get_large_report_buffer): check whether need packaging,, then wait for the arrival of next bag, thereby the closing journal file restarts circulation as needs.This is because when the system data bag is excessive, and therefore the automatic subpackage of meeting need carry out the processing of packaging the recipient.
(8.write_log_sendsock): message received in record in journal file;
9. call fork () and derive from subprocess;
(10.deal_report): in subprocess, handle the message that receives, closing journal file after finishing, and finish subprocess
11. in host process, the closing journal file restarts major cycle.
The program of B, transmission process is mainly
1, open_log opens journal file;
2, am_i_host judges whether oneself is main frame.Three return values are arranged, and return the title of main frame simultaneously:
Status==-1 is not a main frame, and returns the title of main frame:
The current system of status==-2 does not have main frame, and the Hostname that returns is a null character (NUL);
Status==1 is a main frame, and returns the title of oneself.
In this program, called subprogram commonly used a: SelectMyServer, remove to seek main frame by this program.
3, check_local_report checks and preserves local message, and does corresponding processing.It has two to bring parameter into, and status and server_name are respectively the Host Status that obtains after am_i_host calls, and host name.Status is the return value of am_i_host.This program circulates to all systems that define among the connect_system.sys, when be not native system (! Myself) time, then carry out loop body, otherwise circulation again.The work that loop body is finished has:
1) check_local_report_bysystem (): the situation of checking local message by system one by one.The message that need send to this system under this locality all is kept at catalogue with this systematic naming method, is an example with the centralized control system, should be kept to the message that this system sends;
2) whether NotSending (): checking has process to begin to send the local message that need send to this system.Return value is status, if status==1, expression does not have process that this system is being sent local message; If status==0, expression has had process that this system is sent local message;
3) check_send_local_msg (): if preserve the message (local_report_exist==TRUE) that does not send to this system under this system's respective directories, and there is not process this system being sent local message (the return value status==TRUE of NotSending), then carry out fork (), derive a subprocess, be responsible for sending the local message that is kept under the respective directories to this system;
4) if the message that else is this system does not have the local needs of preserving to send, and this machine is not main frame (master server), then carry out rcp_fin (), send a sign to master server, promptly copy the .RcpFin empty file, the notice master server, this machine (being equipped with server) needs the message that sends not corresponding to this system.In this section, called ping_server ().Ping_server () checks whether network can reach master server, and at which network segment can reach, and returns the machine name that is defined on this network segment simultaneously, uses when carrying out rcp for the back.
4, dnet_send_message receives message by dnet.Send message to sending the communication process by dnet, transmit to other system by this process.
5, deal_report handles the message that receives.Definition in this program checkout transys_reptype.sys file is determined the system that these message needs are forwarded to according to the sender of this message, and carries out and send (send_to_system), and trial sends to this system with this message.In calling last parameter of send_to_system, be set to 0 here, whether expression is the real-time packet that receives, and sends for the first time, need and have local message not distribute as yet according to network state and decide the transmission behavior.Finish if this locality still has message not send, then this message will not send, and directly be kept at this locality.
6, send_to_system sends message by network to the receiving system of appointment.
1) this system name is transferred to system number;
2) judge whether to be optional transmission.
3) if then judge:
Is there the message that does not distribute this locality? according to satisfying the purpose that sequential sends, if there is the message that does not distribute as yet this locality, then new message must wait for that the message of front sends the transmission again that finishes, and therefore, this message need be preserved in this locality and not send to network;
If that does not receive server fully duplicates the sign that finishes (expression is equipped with server does not have local message to duplicate), then expression is equipped with the message that server may have transmission or not, so this message can not send, and must locally keep in.After local the preservation, program is promptly returned.
4), send send_to_server to this system according to the number of servers in this system.If send successfully, then program returns 1).
5) as sending failure, then:, then return if local message is forced to send; Otherwise, this message is kept under the local respective directories, become local message.
7, save_msg_local is filename with the current time, is suffix with the newspaper code, and message is kept under the catalogue corresponding to the purpose system with binary file format.
8, NotSending checks corresponding to whether " .IsSending " file is arranged under the respective directories of this system, and this document is to set up when having process to be responsible for to send these local messages of preserving, and finishes back (no matter success or not) deletion sending.
9, check_send_local_msg is according to this machine attribute difference (master server still be equipped with server), and different actions is carried out in decision, send local preserve to local message that should system.Program circuit is:
1) in that this locality that should system is preserved under the message catalogue, generates the IsSending empty file, indicate that the local message of this system is responsible for transmission by " I ".
2), carry out different transmissions according to this machine attribute difference:
For master server (IsHost==1), send_local_report sends message to this system;
For being equipped with server (IsHost==-1), rcp_local_file_to_host, the message that this locality is preserved copies under the master server respective directories, is carried out sending by master server.
3) be sent completely back (no matter whether sending success), delete the .IsSending file under this catalogue, expression sends and finishes.
Distinguishing active/standby server, only allow master server to carry out and send, be equipped with server and do not send, is to carry out in strict accordance with sequential in order to guarantee that message sends.If message can not send according to sequential, then when the recipient carries out corresponding operating, can lead to the failure.
10, this program circuit of send_local_report is as follows:
What 1) detect to be equipped with server duplicates complement mark (RcpNotFin ();
2) if should not indicate, expression is equipped with server replicates not to be finished, and then returns, and does not send.Write down the current time hereof before returning,, then send the warning information (send_warn ()) of " to side system is sent failure " to the alarm window if after 20 seconds, still do not receive this sign.
3), then remove this sign (deletion .RcpFin file), and deletion record had do not receive last time to duplicate and notes the file of time at that time when finishing information if receive this sign.
4) will send (check_send_local_bysystem ()) to network corresponding to the file that is kept under the respective directories of this system
11, RcpNotFin judges whether the copy packet end mark that is equipped with server arrives this machine (master server).Do not arrive, then return 1, expression is not duplicated and is finished; If reached, then return 0, expression is equipped with server has not had message, and master server can begin to send to network.
Receiving process can be arranged according to above transmission process is corresponding, does not give unnecessary details in addition.
Facts have proved, above process makes and can't realize originally that EMS system and SCADA system that data are equipped with mutually realized on the basis of system interconnect in database model integrated design and use router, mode by network message communication between the employing system, not only can be according to jurisdiction and responsibility of maintenance ownership, information sharing realization such as network model maintenance, picture, form are safeguarded, and the real time data that has realized two systems fully is synchronous and shared, thereby reaches the purpose of mutual remote backup.Because above-mentioned remote backup is based upon on original two cover systems fully, therefore to invest minimumly, operational management is very economical.When system moves, neither influence original function, can not cause the storage confusion again, fully excavated the potentiality of power system monitor computer network management system, recover guarantee is provided, be worthy of popularization for the data of meeting accidental disaster.
