Abstract
The protocol conversion and adaptation method for power system communication and architecture is based on the high performance RISC processor and is a distributed architecture composed commonly of MCU distributing on each interface. It can meet the needs of realtime, accuracy, high efficiency for power system, and can adapt message switching among the different communication protocol. The architecture consists of two basic component: TA and HA. TA is the objective adaptation unit implementing the adaptation for physical interface and link of each communication protocol; HA is host adaptive unit implementing the centralized processing and together switching. The whole system consists of a HA and multi TA. The data is sent to HA after TA processes. HA takes data switching based on system requirement to implement the protocol conversion and adaptation.
Description
Technical field power equipment telecommunication protocol is unified standard not so far, can be divided three classes: the 1st, and the self-ordained privately owned stipulations of international business are as 101,1801, CDT, DNP, DEP etc.; The 2nd, industrial control network communication protocol is as ModBus, ProfiBus etc.; The 3rd, directly use ripe communication protocol, as RS232, RS422, RS485, Ethernet, HDLC etc.Numerous just because of agreement, bring very big difficulty for interconnecting between existing equipment.Power system communication stipulations conversions adapts to just with adaptive method and architecture that information translation proposes between different communication protocols.
Background technology power system communication stipulations conversions is based on the high-performance risc processor with adaptive method and architecture and is distributed in the common distribution examination architecture of forming of MCU on each interface.It is simple that risc processor has instruction, carries out the high characteristics of efficient, and MCU industry technology maturation is reliable and stable, adopts distributed treatment then to make systematic unity, opening.All technical characterictics all make power system communication stipulations conversions and adaptive method and architecture can effectively handle electric power system in real time, technical need accurately and efficiently.
Summary of the invention power system communication stipulations conversions and adaptive method and architecture are by 2 basic element of character group energy: TA and HA, TA are the targeted fit unit, finish the physical interface and the link adaptation of each communication protocol; HA is the main frame adaptation unit, finishes focusing on of stipulations, unified conversion.Whole system is made up of a HA and a plurality of TA, data adopt the uniform data structure of distributed treatment to issue HA after TA handles, HA then carries out data transaction according to system requirements, and the data after will changing are again issued corresponding TA, finishes the conversion of power system communication stipulations with adaptive.
Shown in Figure 1 in the structure of description of drawings HA and TA such as the Figure of description.
Have a HA and 2 TA in the embodiment system at least, simultaneously, the number of TA can the actual demand hot plug, plug and play; The inner high-speed bus that uses of distributed processing system(DPS) is to satisfy the peak rate demand of a plurality of TA, and all data are all transmitted after the unified processing of HA; The interface rate of HA is exactly the speed of internal bus, and each TA need use and carries out rate adapted between dual port RAM and internal bus.
Claims (5)
1, forms by TA and HA
TA is the targeted fit unit, finishes the physical interface and the link adaptation of each communication protocol; HA is the main frame adaptation unit, finishes focusing on of stipulations, unified conversion, and whole system is made up of a HA and a plurality of TA.
2, adopt unified internal data format between each TA and HA, to carry out transfer of data
For unified TA interface, be convenient to data transaction, internal system uses a uniform data format to carry out transmitting and receive data between TA, HA, and all TA use this form to send data to HA, and HA also uses this data format to send data to all TA simultaneously.
3, TA independently finish physical interface transmitting-receiving and the link layer data adaptive
It is adaptive that TA can independently finish the interface of line side physical circuit, can deal with data link layer part, payload user data is sent to HA.
4, all data are all transmitted after the unified processing of HA
Whole system is made up of a HA and a plurality of TA, data adopt the uniform data structure of distributed treatment to issue HA after TA handles, HA then carries out data transaction according to system requirements, and the data after will changing are again issued corresponding TA, finishes the conversion of power system communication stipulations with adaptive.
5, can carry out rate adapted between HA and TA
Internal system is used the demand of high-speed bus with the peak rate sum that satisfies a plurality of TA, and all data are all handled the back forwarding through HA is unified.The interface rate of HA is exactly the speed of internal bus, and each TA need use and carries out rate adapted between dual port RAM and internal bus.
