It should be arranged on a secondary six epitope stands, each calibrated meter position matches a power source, 0.05 grade of standard scale and one
Individual error meter, each epitope work independently.
Moreover, each epitope is equipped with a standard scale interface, for external higher precision standard scale periodically to 0.05 grade
Working stamndard table is checked.
Moreover, apparatus structure is configured using upper and lower corresponding, each epitope is from top to bottom followed successively by error meter, checklist, standard
Table, power source, whole calibration equipment are designed as 0.05 grade.
A kind of control method of the asynchronous calibrating installation of single-phase multi-epitope, it is characterised in that：Each epitope of the present apparatus is by one
Individual independent power source control, a device may have more power sources；Verification software is united according to calibration equipment epitope situation
One addressing and setting, are worked using multiple verification software multi-process, control multiple power sources to complete operation, the school of each epitope respectively
Testing work arbitrarily timesharing/while independent progress, i.e., each epitope can run a set of verification software, and whole multi-epitope system is entered more
Journey asynchronous working.
Moreover, checked between different epitopes software interface using manual switching.
Moreover, work overall procedure is as follows：
(1) user logs in；
(2) ammeter supplemental characteristic typing；
(3) checking process is started；
(4) data preserve；
(5) data are checked, are counted, printing.
The advantages and positive effects of the present invention are：
1st, each source of the present apparatus only individually connects the checklist, standard scale and error meter of this epitope, and electrical cable is mutually not
Communicate, each power source can thus require according to the difference of different checklists, different calibrating projects, while carry out difference
Verification task.
2nd, between the multiple electric energy meter verification units of the present apparatus using working method in parallel, phase between each electric energy meter verification unit
Mutual independence, it is independent of each other, is greatly improved than high-power work in series mode in terms of stability, so as to improves inspection
Test precision.
3rd, electric energy meter open circuit is broken down and is detected in the program control source of the present apparatus only can influence this unit, i.e., an epitope is by shadow
Ring, other units still can normal work, the reliability of equipment will obtain increase at double.
4th, the present apparatus is as a result of the time sharing mode of parallel asynchronous, and dress table is examined, than the full table one of serial mode
With calibrating, together switchable load point, repair school wait etc. save to the full extent calibrating the time, improve efficiency.
5th, the present apparatus using it is modular design cause each Bits Expanding it is very convenient, also can according to calibrating amount start-stop epitope,
Energy-saving purpose is reached, from hardware configuration, this programme is to integrate existing multi-epitope device to become multiple single tables
The combination of position device, is to overcome row in actual production although being only capable of being presented as the superposition of monomer unit on word
Technology prejudice in the industry, there is good technique effect, possess unobviousness.

Embodiment
Below in conjunction with the accompanying drawings and the invention will be further described by specific embodiment, and following examples are descriptive
, it is not limited, it is impossible to which protection scope of the present invention is limited with this.
A kind of asynchronous calibrating installation of single-phase multi-epitope, including six independent single-phase stable sources, six 0.05 grade of single-phase marks
The secondary six epitope stands of quasi- table, six single-phase error meters, 0.02 grade of single-phase standard scale, a computer and one, described six
Independent single-phase stable source, six 0.05 grade of single-phase standard scales and six single-phase error meters correspond secondary installed in one respectively
On six epitope stands, each calibrated meter position matches a power source, 0.05 grade of standard scale and an error meter, makes
Each epitope is completely independent work, so as to meet that every epitope can independently verify different size electric energy meter, and can realize timesharing
The asynchronous this flexibility requirement verified.
In order to ensure each epitope error consistency index, each epitope is equipped with a standard scale interface, can be external higher
0.02 grade of standard scale of precision is periodically checked 0.05 level work standard scale.
Referring to shown in accompanying drawing 1 to accompanying drawing 2, device entity structure is configured using upper and lower corresponding, and each epitope is from top to bottom successively
For error meter, checklist, standard scale, power source, whole calibration equipment is designed as 0.05 grade.
Because the control mode of novel calibration device of the present invention and traditional calibration equipment is different, the logical of software is involved
News, the method for operation of software are also different.Traditional single-phase multi-epitope calibration equipment is that a power source controls multiple epitopes, school
Testing software only needs a software instances to control single power source can to complete to require, moreover, traditional single-phase single epitope school
Control on Communication is carried out using unified IP address when the error meter of experiment device uses, then will cause control in this new device
It is chaotic or even uncontrollable.
The innovative point of the control method of the present apparatus is：
Each epitope of new device of the present invention is controlled by an independent power source, and a device may have more work(
Rate source；
Verification software is according to calibration equipment epitope situation unified addressing and setting, using multiple verification software multi-process works
Make, control multiple power sources to complete operation respectively, the verifying work of each epitope can arbitrarily timesharing/and meanwhile it is independent carry out, i.e., often
Individual epitope runs a set of verification software, whole multi-epitope system multi-process asynchronous working.
User, which operates, needs the manual switching between different epitopes software interface to check, advantage of this is that verification software
Versatility is good, calibration equipment epitope number do not influence verification software use, different check is respectively adopted in each epitope of calibration equipment
During scheme, when display interface and single epitope work as it is concise, be more suitable for the continuity of current operation librarian use, can have
Effect reduces operating personnel's requirement and training cost, utilizes the multi-process function of WINDOWS operating systems in itself that target can be achieved
It is required that and Function Extension it is relatively easy.
The work overall procedure of the control method of the present apparatus is as follows：
(1) user logs in；
(2) ammeter supplemental characteristic typing；
(3) checking process is started；
(4) data preserve；
(5) data are checked, are counted, printing.
Although disclosing embodiments of the invention and accompanying drawing for the purpose of illustration, those skilled in the art can manage
Solution：Do not departing from the present invention and spirit and scope of the appended claims in, it is various replace, change and modifications all be it is possible,
Therefore, the scope of the present invention is not limited to embodiment and accompanying drawing disclosure of that.
