For a long time, exchange the instrument verification device and be generally manually calibrating, this calibration method needs testing person's manual operations, and need a large amount of calibrating data of record, because the calibrating comparison of item of rules regulation is many, therefore calibration method efficient is low manually, and testing person's workload is also larger simultaneously, and the processing of data also required a great deal of time after calibrating finished.Whole verification process has testing person's participation from the calibrating of beginning to the generation of last probation redport, and this just causes artificial mistake unavoidably.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of interchange instrument verification device verification system is provided.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of interchange instrument verification device verification system, comprise by standard scale A and the integrated accredited interchange instrument verification device of signal source, innovative point of the present utility model is: this verification system also comprises standard scale B and data processing computer, the signal source of described interchange instrument verification device respectively with standard scale A, standard scale B connects, for standard scale A and standard scale B provide voltage and current signal, standard scale B and accredited interchange instrument verification device are processed computer with data respectively and are connected.
And described standard scale B adopts 0.01 grade of three-phase multifunctional standard electric energy meter of RD-33-473 type of RADIAN company.
And standard scale B and accredited interchange instrument verification device are processed computer by RS232 port and data respectively and are connected.
Advantage of the present utility model and good effect are:
1, the utility model system can read the detection data of standard scale, and can calculate and process data, meets the testing process basic demand, can satisfy DL/T 1112-2009 " AC and DC instrument verification device vertification regulation " requirement.
2, the utility model system has overcome the in the past asynchronism of artificial reading life period error shortcoming, can carry out repeated test to the untrue value that occurs owing to objective factor in the verification process, has embodied the authenticity of this system's human oriented design thinking and data.
3, the utility model system can generate calibration certificate automatically after finishing every test, and generates the corresponding data form behind the Correlation method for data processing, greatly reduces the consumption of a large amount of human resources and the loss of equipment.
4, the utility model system run all right, safe and reliable, the information data collection comprehensively, accurately, the digitizing of operating process, robotization, standardization have promoted detection efficiency greatly, make that the periodic calibration that exchanges the instrument verification device is consuming time to be shortened to originally 1/3rd, have good economic benefit and society generalization and be worth.
Description of drawings
Fig. 1 is system of the present utility model connection diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
Embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model is not limited to the embodiment described in the embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to equally the scope of the utility model protection.
A kind of interchange instrument verification device verification system, as shown in Figure 1, comprise by standard scale A and the integrated accredited interchange instrument verification device of signal source, this verification system also comprises standard scale B and data processing computer, the signal source of described interchange instrument verification device respectively with standard scale A, standard scale B connects, and for standard scale A and standard scale B provide voltage and current signal, standard scale B and accredited interchange instrument verification device are processed computer with data respectively and be connected.
In enforcement of the present utility model, adopt 0.01 grade of three-phase multifunctional standard electric energy meter of RD-33-473 type of RADIAN company as the standard scale B of reference standard, this electric energy meter is processed computer by RS232 port and data and is connected.
In the example verification system, the JW-0301C type alternating current-direct current ammeter calibration equipment that accredited interchange instrument verification device adopts Jiangxi huge little scientific and technological development company limited to produce, this alternating current-direct current ammeter calibration equipment is connected with data processing computer by the RS232 port.
Principle of work of the present utility model is:
⑴ connect the line of whole interchange instrument verification device verification system, starts to exchange instrument verification device and standard scale B and on request preheating;
⑵, log-on data is processed computer, and typing normative reference and accredited device basic data are also formulated the calibrating flow process.
⑶, data read, in two kinds of situation:
1. automatic Verification.Exchange the communication protocol that the instrument verification device mates if exist in the system with tested, the output in system control signal source, and automatically read normative reference and by data such as the voltage of checking device, electric current, power, phasing degree;
2. semi-automatic calibrating.If do not exist in the system and the tested communication protocol that exchanges instrument verification device coupling, need the output of manual control signal source, system only reads the data such as the voltage, electric current, power, phasing degree of normative reference automatically, is needed manual entry by data such as the voltage of checking device, electric current, power, phasing degree;
