Embodiment
The invention provides the means of communication and the device at a kind of remote monitoring and diagnosis center and regional dispatching center, can solve remote monitoring and diagnosis center and regional dispatching center carry out communication in wide area network time due to the inefficient problem of narrow the brought access to netwoks of the bandwidth of wide area network.
As shown in Figure 2, the means of communication at a kind of remote monitoring and diagnosis center and regional dispatching center, remote monitoring and diagnosis center is connected by wide area network with regional dispatching center, and the described means of communication comprise the steps:
Step S1, judges that data transmission is message transmissions or file transfer, if message transmissions enters step S2, if file transfer enters step S3.
Step S2, if message transmissions can be carried out message transmissions as follows between remote monitoring and diagnosis center and regional dispatching center:
Step S201, message recipient responds receiving after message, in the time that not obtaining described message recipient's response in time, message transmitting party (can set in advance a time threshold, exceed this time threshold and do not receive that yet response thinks " not in time obtain "), adopt buffer technology to cushion message, and set maximum retransmission and retransmission time interval;
Step S202, judge whether to exceed described retransmission time interval, temporarily do not send if not message, until resend message while exceeding described retransmission time interval, it is 1 minute that retransmission time interval for example can be set, the super message that resends after one minute a time;
Step S203, judge whether the number of transmissions exceeds described maximum retransmission, continue if not to treat that retransmission time interval carries out message transmissions, if the message also not transmitting is abandoned, then disconnect being connected between described remote monitoring and diagnosis center and described regional dispatching center.
It is worth mentioning that, maximum retransmission and retransmission time interval are set can avoid frequent re-transmission to cause network congestion or aggravation network congestion, disconnect and being connected between described remote monitoring and diagnosis center and described regional dispatching center can impel the remote terminal at regional dispatching center to reconnect remote monitoring and diagnosis center, to improve system run all right.
Step S3, if file transfer, file is compressed, compressed file can effectively reduce file transfer to finite bandwidth occupation proportion, therefore in the time of transfer files on wide area network, use the form after compression to carry out file transfer between described remote monitoring and diagnosis center and described regional dispatching center.In addition because file transfer traffic is large, and randomness is stronger, transmit for reducing the band-limited net environment file of wide area the impact that other message transmissions are caused, the maximum occupied bandwidth threshold value of file transfer is set, in the time that the shared bandwidth of file transfer exceedes described maximum occupied bandwidth threshold value, refuses file transfer requests.
In addition, when journey monitoring, diagnosing center and remote terminal carry out communication in wide area network except wide area network bandwidth is narrow cause access to netwoks efficiency poor, also there is the larger problem of bandwidth fluctuation of wide area network, this is due to the multilayer route via node in process Wide Area Network in the middle of the two ends of communication, 2M circuit is to divide by large optical fiber transmission network the dedicated network splitting out, but its relay processes is all by fiber optic network processing, its processing procedure and other 2M private networks share, be subject to processing the restriction of ability, sometimes network delay is larger, bandwidth can further reduce.For solving the problem that this bandwidth fluctuation is large, in described message transmission procedure, can also comprise step S204: wide area network bandwidth is monitored, when narrowing, the wide area network bandwidth monitoring (threshold value can be set, if monitor bandwidth lower than this threshold value, can think and reach the requirement of " narrowing ") time, message is cushioned, and strengthen retransmission time interval and reduce maximum retransmission; And after the wide area network bandwidth monitoring is recovered normally (this normal value refers to value set in step S201), network transmission speed can promote, described retransmission time interval and maximum retransmission are returned to normal value, and by overstocked buffering message end of transmission successively, so just can effectively avoid the idle and message backlog of the network bandwidth.
The above-mentioned processing procedure for message transmissions in the larger situation of fluctuation situation, processing procedure in file transfer shows as and can also comprise step S301: set in advance bandwidth threshold value, if the wide area network bandwidth monitoring is refused file transfer requests lower than this bandwidth threshold value.This method that file transfer is provided to limit bandwidth, not only guarantee the efficiency of large file transfer, also guarantee that certain RSVP is to the transmission of other messages simultaneously, avoided because narrow file transfer in situation of bandwidth causes the situation of network congestion or bust this
Under the applied environment of wide area network, between same 2M private network or multiple private network, may there is the situation of a large amount of Concurrency Access, the message transmissions so telecommunication network being caused is impacted very large, likely produces network congestion, recovers consuming time longer.To this, before described step S1 judges that data transmission is message transmissions or file transfer, can also comprise step S0: the waiting list of connection request is set, in the time that connection request quantity exceeds the length of this waiting list, refuses new connection request.Can realize the control to remote terminal connection request quantity by above-mentioned steps, prevent that the network transmission performance under concurrency emergency case from declining.
Due to the concurrent requirement of data link of file transfer, need multiport to use simultaneously, and wide area network transmission needs passing fire wall, therefore must limit port range, as a good embodiment, can adopt fixed port scope at file transfer port, to coordinate fire compartment wall setting, improve security of system.
In addition, it should be noted that, described message transmissions has comprised database transmissions.
Be illustrated in figure 3 the mutual schematic diagram of data flow between remote monitoring and diagnosis center (service end) and regional dispatching center (client or be referred to as remote terminal), process description is as follows:
(1) client-side program inquiry commercial data base operation calls database manipulation interface, after interface encapsulation message, is transmitted to message interaction interface;
(2) message interaction is transmitted to service end Correspondent (remote terminal access agency service) by remote terminal communication program;
(3) service end agency is by mutual database message repeating to database manipulation Agent, and this program, by analyzing message content, is translated into commercial data base operation;
(4) database broker is mutual by commercial data bank interface and commercial storehouse, and result is packaged into message turns back to remote terminal.Guarantee that commercial data base is not exposed in wide area network, enhances system security;
(5) forwarding by remote terminal communication program alternately of client application and background service process or real-time data base, repeating process is transparent to client application, can realize point-to-point message and event message and forward;
(6) service end Correspondent receives after remote terminal communication program E-Packets and is transmitted to background service process or real-time data base;
(7) file is mutual with service end file transfer services through the forwarding of thin-client communication program by file transfer protocol (FTP), and realizes file transfer.
