Abstract
The invention relates to a method for detecting a power line, which comprises the steps as follows: power is initialized; cable numbers are set; a test is started; carrier wave is tested; response terminal is conformed; timing synchronization command is sent; acquisition command is sent; a main station and each on-line terminal acquire data for N times simultaneously; the main station reads each on-line terminal data successively; the main station compares and judges the data; whether unique confirmation exists is detected, if yes, a confirmation command is sent to a confirmed terminal; whether a line test is ended is detected, if yes, the test is finished. Compared with the prior art, the method has the advantages that connection of each line can be easily detected and the requirement of live detection for a low-voltage power line can be met.
Description
Technical field
The present invention relates to the line of electric force wireline inspection, particularly electric power line detecting method.
Background technology
In the process of Pudong electric company power distribution information transformation, a problem of running into is in low-voltage power line, from distribution substation many circuits that come out, but can not determine the corresponding situation of concrete connection of these circuits and following one-level, therefore cause the difficulty of the project implementation, if adopt the identification of carrying out circuit under the artificial situation of cutting off the power supply, will cause significant impact to resident's productive life, so can not use the method for outage implements, therefore need a kind of conveniently device of exploitation, can under situation about not having a power failure, check out the connection situation of low-voltage circuit easily, the exploitation of this project will be based on the power-line carrier communication of the maturation of Shanghai Jiulong Electric Power scientific ﹠ technical corporation, by the master-slave equipment of exploitation based on power line carrier communication, can make things convenient for, finish the identification of the connection situation of low-voltage power line efficiently.
Summary of the invention
Purpose of the present invention is exactly that a kind of convenience, succinct electric power line detecting method are provided in order to overcome the defective that above-mentioned prior art exists.
Purpose of the present invention can be achieved through the following technical solutions: electric power line detecting method, it is characterized in that, and may further comprise the steps:
(1) power-up initializing;
(2) cable number is set;
(3) begin test;
(4) carrier test: reply terminal check;
(5) send regularly synch command;
(6) send acquisition: main website and each online terminal are gathered the N secondary data simultaneously;
(7) main website reads each online terminal data successively;
(8) main website compares judgment data;
(9) detect whether unique affirmation is arranged, if testing result then skips to step (13) for not;
(10) if the testing result of step (9) is for being then to send to the terminal of confirming and confirm to order;
(11) whether the detection line test finishes, if testing result then skips to step (14) for not;
(12) if the testing result of step (11) is for being, this TV station change end of test (EOT) then;
(13) select senior judgment model, and return step (6);
(14) test next circuit, and return step (2).
Compared with prior art, the present invention can detect the connection situation that each bar occurs easily, can satisfy the advantages such as requirement of the charged detection of low-voltage power line.

Embodiment
As shown in Figure 1, electric power line detecting method of the present invention may further comprise the steps:
(1) power-up initializing;
(2) cable number is set;
(3) begin test;
(4) carrier test: reply terminal check;
(5) send regularly synch command;
(6) send acquisition: main website and each online terminal are gathered the N secondary data simultaneously;
(7) main website reads each online terminal data successively;
(8) main website compares judgment data;
(9) detect whether unique affirmation is arranged, if testing result then skips to step (13) for not;
(10) if the testing result of step (9) is for being then to send to the terminal of confirming and confirm to order;
(11) whether the detection line test finishes, if testing result then skips to step (14) for not;
(12) if the testing result of step (11) is for being, this TV station change end of test (EOT) then;
(13) select senior judgment model, and return step (6);
(14) test next circuit, and return step (2).
As described in Figure 2, detector main frame and terminal are partly made by controller main frame, carrier communication module, electric weight detection module, power module and display module etc.Electric weight detects and selects the high-performance electric quantity acquisition module for use, and the ADC analog to digital conversion circuit of the ∑-△ on front end 6 passages 2 rank is sampled to input signal, and inner high performance 24 bit DSP digital signal processors are finished inner triphase parameter and handled.
Carrier communication adopts special electric power carrier communication SoC chip, uses special carrier modulation demodulation method, cooperates special communication coding/error correction algorithm, has characteristics such as antijamming capability is strong, long transmission distance.
