The utility model content
The utility model purpose: to the problem and shortage that above-mentioned prior art exists, the purpose of the utility model provides a kind of electric energy quality monitor accuracy test device, increases work efficiency and eradicates mistake.
Technical scheme: for realizing above-mentioned utility model purpose; The technical scheme that the utility model adopts is a kind of electric energy quality monitor accuracy test device; Comprise standard source, standard device, seized equipment, the network switch, first server and second server; Said standard device is connected standard source respectively with seized equipment, and said standard device, seized equipment, first server and second server are connected to form a LAN through the network switch; Said standard source is used to produce seized signal; Said standard device and seized equipment are used for gathering respectively seized signal and produce packet respectively; And the packet of inciting somebody to action separately through the network switch uploads to first server; Said second server is used for reading the first data in server bag through the network switch, and will compare from the packet of standard device and packet from seized equipment.Need to prove that " standard device " in the utility model and " seized equipment " all are electric energy quality monitors, just the precision of standard device is higher than seized equipment, and such as the accuracy requirement 1% of seized equipment, and the precision of standard device reaches 0.5%.
Further, the quantity of said standard device is 1, and said seized amount of equipment is at least 1.
Further, said packet is the PQDIF packet.
A kind of electric energy quality monitor inspection method of accuracy comprises the steps:
(1) produces electric power signal by standard source;
(2) standard device and seized equipment are gathered electric power signal respectively, handle power quality data and generate the PQDIF packet;
(3) standard device and seized equipment upload to first server through the network switch with PQDIF packet separately respectively;
(4) second server reads the PQDIF packet of first server through the network switch;
(5) second server will compare from the PQDIF packet of standard device and PQDIF packet from seized equipment.
Further, said step (4) also comprises: second server is resolved respectively from the PQDIF packet of standard device and PQDIF packet from seized equipment, and unified tunnel name and standardized data formats.
Further, in the said step (5), statistics is from the PQDIF packet of standard device and total node, privately owned node and channel data deviate from the PQDIF packet of seized equipment.
Further, also comprise step (6): with the PQDIF packet from standard device is benchmark, judges whether node from the PQDIF packet of seized equipment lacks and whether each channel data deviate exceeds standard.
Further, the quantity of said standard device is 1, and said seized amount of equipment is at least 1.
Beneficial effect: the utility model electric energy quality monitor accuracy test device; 1 people can accomplish several electric energy quality monitor accuracy tests and form report in 1 hour; The contrast manual detection: 1 people accomplished an electric energy quality monitor accuracy test in 1 day and forms report; The utility model has improved the work efficiency of check greatly, and mistake can not take place.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
As shown in Figure 1, standard source, standard device, some seized equipment, the network switch, ftp file server and check server are formed electric energy quality monitor accuracy test device.
As shown in Figure 2, standard source produces electric power signal, standard device, seized equipment 1 ..., seized equipment n gathers the electric power signal that standard source produces simultaneously, form quality of power supply PQDIF formatted data bag PQDIF0, PQDIF1 ..., PQDIFn; Via the network switch with PQDIF0, PQDIF1 ..., PQDIFn uploads to the ftp file server; Detect server via network switch scanning ftp file server, download PQDIF0, PQDIF1 ..., PQDIFn is to local; PQDIF check comparison module with PQDIF1 ..., PQDIFn respectively with PQDIF0 relatively, obtain respectively report 1 ..., the report n.
PQDIF document analysis as shown in Figure 3, that standard device generates, one of them DS value is respectively:
0.00013101
0.00010437
227.207101
239.127302
0.00020243
0.00020230
PQDIF document analysis as shown in Figure 4, that certain seized equipment generates, one of them DS value is respectively:
0.00010101
0.00010101
229.437437
237.127377
0.00020202
0.00020202
As shown in Figure 5; Certain seized Equipment Inspection report sample (part); Report divides two parts: first is " PQDIF file structure compare test report "; Have 1840 same node point, 15 disappearance nodes, the subitem testing result all is qualified, but 15 places of two places of proposed amendments, suggestion increase; Second portion is " PQDIF file ratio of precision is than test report "; " tunnel name " hurdle be " Pst of VAN " (flickering in short-term) maximum error 2.2303360 with mean square deviation 1.2229812 all less than discriminant value (2.5000000,1.5000000), it is qualified that this index is judged.
