Technical field
The present invention relates to the data communication field of electric power system terminal, particularly relate to a kind of distribution terminal data communications method and be applicable to the distribution terminal network of the method.
Background technology
Because the amount of capacity of electric power system distribution switching station differs, and need to reserve following capacity extension, therefore require distribution network terminal equipment observing and controlling capacity to have autgmentability flexibly, for this reason, the general technical schemes that adopt many CPU intelligent assembly more.
To realize exchanges data between each processor in the multi-CPU system, therefore adopt the technical scheme that many CPU can only component communication to exist big capacity slow data exchange and sudden short frame to prohibit the contradiction of emergency data transmissions, make that easily emergency data can not get priority treatment when the transmission of large capacity data.
How under the situation of cost control, the exchanges data real-time and the contradiction between the throughput that solve between many CPU intelligent assembly become in the present data communication control field, particularly problem demanding prompt solution in the data communication of the electric power system control field.
?
Summary of the invention
In order to solve in the electric power system data Control on Communication field, there is the problem of exchanges data real-time and throughput contradiction between many CPU intelligent assembly, the present invention proposes a kind of distribution terminal data communications method, may further comprise the steps:
Terminal equipment sends online logon information, and passes through first bus transfer to main website;
Main website inquires each terminal equipment according to online terminal equipment in turn by second bus, and obtains periodically big capacity slow data by the information collection function of terminal equipment;
Main website adjusts the configuration information of terminal equipment according to the big capacity slow data of periodicity that terminal equipment provides, and realizes the switching of switch by terminal equipment;
The execution of not interrupting, circulate of above step;
When terminal equipment monitors sudden short frame emergency data, by first bus this emergency data is sent to main website;
The sudden short frame emergency data that main website provides according to terminal equipment after confirming, analyzing, is issued to terminal equipment by first bus with guidance command, terminal equipment according to guidance command immediately to the switch execution control function;
Described first bus is the bus with arbitration function, and described second bus is for supporting the bus of poll pattern.Further, described sudden short frame emergency data is remote signalling displacement data in the present invention.
Simultaneously, the invention also discloses the big capacity slow data of described periodicity is configuration information, variation telemetry, recorder data.
Simultaneously, the further optimization of the present invention discloses and has been the PIO data-transmission mode between described main website and the terminal equipment.
The present invention discloses the distribution terminal network that is applicable to above-mentioned distribution terminal data communications method, described distribution network comprises main website, terminal equipment; Described terminal equipment is connected with main website by first bus, is connected with main website by second bus simultaneously; Described first bus is the bus with arbitration function, and described second bus is for supporting the bus of poll pattern.
Further, the invention discloses described first bus is the CAN bus.
Further, the invention discloses described second bus is 485 buses.
At last, the present invention also optimizes and discloses in described main website and the terminal equipment microprocessor that device respectively is useful on exchanges data.
Technical scheme disclosed in this invention is the dual bus communication mode, first bus wherein, the bus that just has arbitration function, preferred especially disclosed CAN bus in the present invention for example, this bus mainly is responsible for the transmission of data-signals such as logon information, sudden emergency data and control command, such as remote signalling displacement data, guidance command etc.; Second bus just can be supported the bus of poll pattern, preferred especially disclosed 485 buses in the present invention for example, and this bus mainly is responsible for the periodically transmission of Large Volume Data, such as configuration information, variation remote measurement, recorder data etc.Second bus is responsible for transfer of data routinely, and when urgent bursty data produced, because the data distribution of dual bus pattern, this information can meet with a response immediately, and therefore the transmission of recorder data simultaneously can not suspend or interrupt yet.
Thereby solved the contradiction of big capacity slow data exchange and sudden short frame emergency data transmissions.
