Abstract
The invention provides a method for testing the safety protection of a power meter, which comprises the following steps: S1: simulating all possible passwords through a computer and testing the password authority of the power meter through the passwords; S2: testing whether the corresponding password corresponds to the authority of the password or not; S3: the result of adopting the normal authority for carrying out operation on the power meter is successful and the result of adopting the abnormal authority for carrying out the operation on the power meter is failed; S4: respectively verifying the power quantity zero-clearing function of the power meter, the maximum demand zero-clearing function of the power meter, the event zero-clearing function of the power meter and the writing function of the power meter and carrying out the testing of the steps; and S5: alarming by the computer if the abnormities occur in the functions of the power meter in the step S4.
Description
Technical field
The present invention relates to electric power and communication technique field, particularly about a kind of method of testing of safety protection of power meter.
Background technology
In electric system, often face the problem of user's stealing, give to supply a some department to cause great loss, how anti-electricity-theftly become the important topic of power department.Along with the anxiety of electric power supply, the electric energy meter safety practice is more and more important, and effectively safety practice can not only prevent user's stealing change data, also can prevent user's misoperation, perhaps without permission and the illegal operation of carrying out inspection.
But because the complicacy of electric energy meter safety protection technique, existing detection means can not reflect whether stealing of user exactly, whether breaks through security protection, and whether the electric energy meter safeguard function is perfect, needs a kind of special detection technique.Therefore whether accurately and reliably, whether the safety prevention measure of certain electric energy meter meets the requirements, and how realizes this technological degree,, all become a unknown number.So, although much work at the scene, and claim that oneself is safe and reliable with electric energy meter, can prevent various electricity filching means, owing to there is not suitable detection means, this function is not effectively verified.This buying to electric system has proposed a brand-new challenge.From present actual situation about using; There is the safety prevention measure of part electric energy meter not in place; The situation that has rudimentary authority also can operate super-ordinate right takes place; Also have the feelings of the write permission of not being provided with to occur, these some underproof products of explanation have been applied in the reality, use a kind of effective detection means to detect the active demand that this function has become power department.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the present invention provides a kind of method of testing of safety protection of power meter that can the electric energy meter security protection.
The technical solution adopted for the present invention to solve the technical problems is: the method for testing that a kind of safety protection of power meter is provided; It may further comprise the steps: S1: draw up all possible password through computer mould, and through this password the password authority of electric energy meter is tested;
Whether S2: it is corresponding with its authority to detect corresponding password;
S3: adopting normal authority that ammeter is carried out operating result is successfully, and undesired authority is carried out operating result to ammeter and is failure;
S4: respectively to the electric weight Protection Counter Functions of electric energy meter, the maximum demand Protection Counter Functions of electric energy meter, the incident Protection Counter Functions of electric energy meter and electric energy meter write the test that above-mentioned steps is carried out in functional verification;
S5: unusual if the function of the electric energy meter among the step S4 occurs, computing machine can be reported to the police.
The scheme of the further technical solution problem of the present invention is: among the described step S3, operating successfully has replying of success, and operation failure has replying of failure, perhaps no response.
The scheme of the further technical solution problem of the present invention is: among the described step S3, and high authority person can accomplish low rights person's function, the low rights person cannot accomplish high authority person's function.
Compared to prior art; The method of testing of safety protection of power meter of the present invention is simulated various legal use electric energy meter security systems and the illegal method of using the electric energy meter security system; Contain the possible situation that various safety precautions run into as far as possible, correctly detect under this kind situation the correct response that electric energy meter should be made; Thereby the authority to different ciphers was directed against is carried out validation test; Find whether to have the situation that exists password not corresponding, thereby realize the various security situations of electric energy meter are tested, improve its security with authority.
Description of drawings
Fig. 1 is the schematic flow sheet of the method for testing of safety protection of power meter of the present invention.
Embodiment
Following content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
The invention provides a kind of method of testing of safety protection of power meter; It simulates various legal use electric energy meter security systems and the illegal method of using the electric energy meter security system; Contain the possible situation that various safety precautions run into as far as possible; Correctly detect under this kind situation the correct response that electric energy meter should be made.
The method of testing of described safety protection of power meter may further comprise the steps:
S1: draw up all possible password through computer mould, and the password authority of electric energy meter is tested through this password;
Whether S2: it is corresponding with its authority to detect corresponding password;
S3: adopting normal authority that ammeter is carried out operating result is successfully, and undesired authority is carried out operating result to ammeter and is failure; Operating successfully has replying of success, and operation failure has replying of failure, perhaps no response; High authority person can accomplish low rights person's function, the low rights person cannot accomplish high authority person's function;
S4: respectively to the electric weight Protection Counter Functions of electric energy meter, the maximum demand Protection Counter Functions of electric energy meter, the incident Protection Counter Functions of electric energy meter and electric energy meter write the test that above-mentioned steps is carried out in functional verification;
