(a) inquiry basic parameter

Inquiry basic parameter interface receives a device identifier (IP) parameter, the WebService server is interface conversion the communication protocol that equipment is corresponding, after communication protocol was returned to relevant parameter, the WebService server was converted to parameter the XML form and returns.Described basic parameter comprises: voltage change ratio, electric current no-load voltage ratio, the voltage mode of connection, the electric current mode of connection, rated voltage, rated frequency, busbar voltage grade.

(b) basic parameter is set

2 parameters of basic parameter interface receiving equipment identifier (IP) and XML character string are set, in the XML character string, comprised the basic parameter of equipment, it is interface conversion the communication protocol that equipment is corresponding that the WebService server receives orders rear, by the communication protocol of equipment, equipment is carried out to the parameter setting again, arrange and successfully return very, unsuccessfully return to vacation.

C. the limit value of reporting to the police configuration arranges

(a) obtain the limit value parameter

Obtain limit value parameter interface and receive a device identifier (IP) parameter, the WebService server is interface conversion (likely corresponding many of the communication protocols that equipment is corresponding, because may obtain not only limit value parameter), after communication protocol was returned to relevant limit value parameter, the WebService server was converted to the limit value parameter XML form and returns.The limit value parameter comprises: voltage resultant distortion rate limit value, electric current resultant distortion rate limit value, the voltage fluctuation limit value, flickering limit value when long, the Short Term Flicker limit value, the voltage deviation limit value, the power factor limit value, the frequency departure limit value, voltage positive sequence component limit value, voltage negative sequence component limit value, voltage zero-sequence component limit value, electric current positive sequence component limit value, electric current negative sequence component limit value, current zero sequence component limit value, Voltage unbalance degree limit value, the current unbalance factor limit value, 2-50 subharmonic voltage limit value, 2-50 primary current harmonic limits.

(b) the limit value parameter is set

2 parameters of limit value parameter interface receiving equipment identifier (IP) and XML character string are set, the limit value parameter that has comprised equipment in the XML character string, it is interface conversion the communication protocol that equipment is corresponding that the WebService server receives orders rear, by the communication protocol of equipment, equipment is carried out to the limit value setting again, arrange and successfully return very, unsuccessfully return to vacation.

D. waveform is recorded ripple

This interface receives a device identifier (IP) parameter, and the WebService server is interface conversion the record ripple order of equipment, and after communication protocol was returned to relevant Wave data, the WebService server was converted to data the XML form and returns.Wave data comprises channel number, time, time offset, the n that counts, puts interval time, a n waveform data points.

(2) power quality monitoring device manufacturer realizes standard interface,

When equipment vendors are carried out to remote monitoring, do not need to revise the equipment stipulations, only need to the equipment stipulations, encapsulate and get final product according to the good WebService standard interface of afore mentioned rules.

(3) the equipment essential information is joined to man-machine interface

For the equipment of supporting standard interface, first equipment essential information and channel information to be joined to man-machine interface; (the equipment essential information comprises: equipment abbreviation, equipment vendors, unit type, IP address, port numbers, affiliated transformer station, whether install GPS to the time equipment etc.) (channel information comprises channel position, association channel, monitoring location, channel type, signal type, electric pressure, minimum capacity of short circuit, power supply capacity, User Agreement capacity etc.)

(4) call standard interface and realize the monitoring to equipment

After above-mentioned steps at the man-machine interface place by calling standard interface, while realizing the getting of various device, to the time, the inquiry basic parameter, basic parameter is set, inquiry limit value, configuration limit value, send the monitoring of record ripple order etc.

Of the present invention Beneficial effectFor:

1, solved the difficult problem of the long-range unified monitoring of a plurality of monitoring equipments of electric company.Before using the present invention, there is oneself independently monitoring software in each monitoring equipment manufacturer of electric company, is not integrated in unified man-machine interface, causes management inconvenient, uses trouble, and easily forms information island.

2, adopt the WebService technology to encapsulate conversion to the equipment stipulations, realized standard interface with minimum cost.With the definition Standards Code, realize that integrated method compares, this method is more reliable and more stable and be easy to realize.The method of definition Standards Code necessarily requires all devices manufacturer to revise the equipment stipulations, because various device running environment differs greatly, easily causes the equipment fluctuation of service, and required cost is considerably beyond the cost of encapsulation conversion.
