Second step:, can data and the self information that data processing equipment receives be carried out modeling again according to said frame.For example, be example with a logic device, the modeling flow process is referring to meaning shown in Figure 6.The effect of logical device is based on communication objective to logical node with data set is assembled and merger.
Need to prove that the present invention adopts communication protocol stack standard, sampled value mode aspect such as application level function and the realization of presentation layer function in the mapping of communication protocol stack and protocol stack all in device, to realize:
The communication protocol stack specification technique carries out concrete norm to 051 7 layer models.Wherein physical layer Ethernet speed is relevant with sample rate; The sample rate of confirming transformer differential protection among the present invention is phases 36 point weekly; Because merge cells sends Frame length and fixes; Be 984bit/s,, calculate as follows: (36 * 50Hz) * 984bit=1.771Mbit/s < 10Mbit/>s so the Ethernet rate selection 10Mbit/s between itself and the switch gets final product.Because to the high real-time requirement of sampled value transmission, for avoiding delaying time at the letter storehouse, message will map directly to data link layer, transport layer, network layer etc. is empty.
Said sampled value mode comprises the mapping techniques of object name, object reference, common data class etc. at the mapping techniques of communication protocol stack.
Application layer and presentation layer function realize in the said protocol stack, and application layer is responsible for one or more application service data cells (ASDU) are assembled an APDU Application Protocol Data Unit (APDU) being put before the people sends buffering area.When sample rate is higher, need APDU to gather a plurality of ASDU, sample rate is phases 36 point weekly here, APDU can only comprise 1 ASDU in the mapping.
Presentation layer adopts abstract syntax notation (ASN.1) that abstract data type is encoded among the present invention.For IEC 61850-9-2, ASN.1 coding requirement ratio is easier to, because the packet content that merge cells sends has concrete regulation, when APDU only comprised 1 ASDU, message length immobilized.
The course of work of this device is such: clock synchronization module, other type protocol data processing module, IEC 61850-9-2 protocol processes model and GOOSE message identification module belong to software section; The process layer is by parallel data channel transfer protocol data; Carry out protocol conversion by other type protocol data processing module; The pps pulse per second signal that provides according to clock synchronization module then carries out interpolation or extracts and handle in CPLD; And stamp time tag, and send into IEC 61850-9-2 protocol process module and GOOSE message identification module, be divided into the 61850-9-2 data message according to sampled value, on off state information subsequently and the GOOSE message sends to bay device.Number of data points can be revised in initial configuration according to state's network mark is accurate.The support of this conversion equipment is changed secondary side analog quantity Direct Sampling simultaneously.Sample rate can be set by initial setting up, and high sampling rate can reach 10M SPS.
Although top specific embodiments of the invention is described; But should be understood that; The invention is not restricted to the scope of embodiment, to those skilled in the art, as long as various variations appended claim limit and the spirit and scope of the present invention confirmed in; These variations are conspicuous, and all utilize innovation and creation that the present invention conceives all at the row of protection.
