Fig. 1 is a structured flowchart of the present invention;
Fig. 2 is a workflow diagram of the present invention.
Embodiment
The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment.
See also Fig. 1, Fig. 1 is the structural representation that distribution communication management device and far-end (Surveillance center, control centre etc.) communicate, and the distribution communication management device carries out transfer of data by GPRS telecommunications network and far-end.Described distribution communication management device comprises processing unit 1, memory cell 2, GPRS remote communication interface 5 and a plurality of local communication interface 4; GPRS remote communication interface 5 is linked into processing unit 1 with each local communication interface 4, and each local communication interface 4 links to each other with the local device (not shown) respectively.Processing unit 1 and GPRS remote communication interface 5 and each local communication interface 4 intercom mutually by communication bus.GPRS remote communication interface 5 is connected with telecommunications network, and far-end obtains data by telecommunications network.Realize the local device transfer of data being arrived far-end by a communication port.
Remote communication interface among Fig. 1 is linked into the GPRS wireless-transmission network, and low-voltage distribution is not strict real-time to the requirement of transfer of data, and the GPRS wireless network has certain transmission delay, but satisfies the requirement of low voltage distribution field centralized monitor transfer of data.
Be provided with a protocol processing unit 3 at far-end.When far-end sends to each local device, search local destination address through the packet of protocol processes by the sign that described packet contains.Thus, improvement transferred to upgrade above the software be used for protocol processes, so just reduced the trouble that renewal brought hardware.
During upstream data, packet is transferred to processing unit 1 by communication bus from local communication interface 4, and treated unit 1 is handled the back and arrived GPRS remote communication interface 5 by transmission; During downlink data, packet is transferred to processing unit 1 by communication bus from GPRS remote communication interface 5, and treated unit 1 is handled the back and arrived local communication interface 4 by transmission.
See also Fig. 2, in the process of transfer of data, can run into the problem of contention communication channel.The scene is not only monitored device often, since will there be the situation of contention communication port in many shared channels of monitored device.In the distribution communication management device, each local communication port contention GPRS wireless channel has been adopted the technology of dynamic circulation priority, this technology is carried out according to following steps:
A. the monitored object of low voltage distribution field is divided into different classes ofly, is specially alarm class, remote measurement class, event class, alarm class, protection category information, pulse cumulative amount class, remote control class;
B. can determine the channel occupancy priority of different classes of monitored object according to the classification of monitored information, because the characteristics of power industry, the priority of acquiescence should be that the alarm category information is the highest, and the remote control category information takes second place, and event class, protection class, remote measurement class, pulse class be that All factors being equal, preference will be give to grade;
C. to the monitored information of All factors being equal, preference will be give to level, adopt the circular priority mode, first constantly event class information under this priority, take the GPRS communication channel, second constantly protects category information to take the GPRS communication channel under this priority, the rest may be inferred;
D. the transfer of data in the communication channel that priority is the highest is behind far-end, reduce the priority of this communication channel, priority is dropped to minimum, if but have the alarm category information to occur, still be made as the alarm category information the highlyest, can guarantee that like this equipment abnormal conditions can not occur;
When data when telecommunications network is sent to local device, also can comprise following process: the telecommunication protocol character is resolved and is called, if produce the valid data frame, then calls the Frame analytic process, and with data frame transfer to corresponding local communication Extended Capabilities Port.
The telecommunication passage not only can adopt the GPRS wireless-transmission network, can also adopt data transfer modes such as telephone wire, optical fiber, carrier wave, microwave, short message.
Above example is the unrestricted technical scheme of the present invention in order to explanation only.Any modification or partial replacement that does not break away from spirit and scope of the invention all should be encompassed in the middle of the claim scope of the present invention.
