The mode that the transmission of electric power data and networking are adopted at present is: a branch machine controller disposes a GPRS/CDMA wireless network or ethernet communication module, is connected to the back bench control system through GPRS/CDMA business platform or twisted-pair feeder then.The shortcoming of this communication mode is: there are how many extension sets just to need corresponding a plurality of wireless network modules of configuration and Sim card, or ethernet module and twisted-pair feeder, cause frame net cost too high, it is many to take resource, does not meet the low-carbon environment-friendly requirement.
Summary of the invention
To the problems referred to above, the utility model provide a kind of net cost low, take that resource is few, the distributed director of the succinct communication of low-carbon environment-friendly.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
A kind of distributed director of succinct communication; Comprise contact manager and some minutes machine controllers; Divide machine controller to be connected with the contact manager communication, be provided with in the contact manager and be used for the network communication module that is connected with the background controller system communication through fieldbus.
As preferred embodiment, said fieldbus is controller local area network (CAN).
As preferred embodiment, said network communication module is GPRS/CDMA module or ethernet module.
As preferred embodiment, be provided with communication interface in the said minute machine controller.
As preferred embodiment, said contact manager is provided with the man-machine interface that is used for branch machine controller operating state.
The beneficial effect of the utility model is: the utility model frame net cost is low; It only needs a network communication module can realize that just all divide being connected of machine controllers and background controller system, and the background controller system can control the electric power situation of each minute machine controller working line section, monitors electric network information; Electric power resource is optimized allotment; Divide the machine controller expansion convenient, divide machine controller to need not directly to be connected, so it has, and the resource of taking is few, the advantage of low-carbon environment-friendly with the backstage.
Description of drawings
Further explain below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the block diagram of system of the utility model.
Embodiment
With reference to Fig. 1; The distributed director of a kind of succinct communication of the utility model; Comprise contact manager and some minutes machine controllers; Divide machine controller to be connected with the contact manager communication, be provided with in the contact manager and be used for the network communication module that is connected with the background controller system communication through fieldbus.Preferably be provided with the man-machine interface that is used for branch machine controller operating state on the contact manager.Man-machine interface can directly show the state of the high-voltage switch gear of each minute machine controller, has various communications protocols.Can revise the communication protocol mode of each extension set and main frame through this contact manager, main communication mode is: 101 balances, and 101 is non-equilibrium, and 104 etc.
In the embodiment in figure 1, divide machine controller to comprise A phase Ia, B phase Ib, C phase Ic, zero sequence Io current sampling circuit, metering circuit; Ua, Ub, Uc voltage sampling circuit, system power supply is handled, and opens into detection; The bus receiving circuit, extension set main control unit, man-machine interface; Digital output circuit, clock circuit etc.Contact manager also comprises clock circuit, bus receiving circuit, main frame main control unit etc. except network communication module, man-machine interface.
Three-phase and zero sequence sample circuit primary side are connected with electrical network A, B, C three-phase phase line instrument transformer respectively; Metering circuit combines the power network current collect, electrical network PT voltage, the current power factor of analysis-by-synthesis electrical network, active power, reactive power etc.; Power supply managing is for converting the additional power source voltage in the particular range into controller required working power; Open into detection and refer to that all are received high-voltage switch gear comprises that switching values such as a deciliter contact, energy storage contact, latch contact isolate monitoring; Bus receiving circuit realization each minute machine controller is connected with contact manager; Man-machine interface comprises indicator light demonstration, liquid crystal display, button operation etc.; Digital output circuit comprises that the electric work to high-voltage switch gear divides closing operation output, stored energy operation output etc. to control; Clock circuit has the module of accurate timing, battery, battery charger for adopting, and accurately the time point of record circuit fault generation is accurate to the ms level; The media that the network communication module of main frame is then communicated by letter with the back bench control system for the main frame main control unit, this network communication module is preferably GPRS/CDMA module or ethernet module.In addition; The branch machine controller of the utility model also can further be provided with communication interface; Like 485/232 interface in the present embodiment, GPRS interface, divide machine controller to utilize this 485/232 interface to join with computer, utilize the GPRS interface directly to communicate by letter with the back bench control system.
As preferred embodiment, said fieldbus is controller local area network (CAN), and shown in present embodiment, in the case, the bus receiver on contact manager and the branch machine controller is set to the CAN receiving circuit respectively.The attachable network node of CAN communication mode is unrestricted, and transmission range is far away, and transmission speed reaches 1Mbit/s, inside is integrated error detector and administration module, the real-time and the reliability of raising communication.
During the utility model work; Divide machine controller data such as A phase current, B phase current, C phase current, zero-sequence current, Ua phase voltage, Ub phase voltage, on off state to be input to main control unit through sample circuit; Can realize logics such as syllogic protection, reclosing function, small current neutral grounding protection, function; Analyze the operation of power networks situation, for the network optimization allotment provides data; Contact manager again through the CAN receiving circuit with each minute machine controller be connected; On off state with the protective wire highway section of each extension set control; Circuit ruuning situation is sent to contact manager in real time; Contact manager is connected to the background controller system through Ethernet or GPRS/CDMA module again, and back bench control system receives each minute machine information from contact manager in real time.The characteristics of the utility model are to realize back bench control system and each minute the communicating by letter of machine controller through a contact manager as main frame, can realize that four is distant to each minute machine controller, to the time etc. function, realize centralized management, allocate.
