step one, sensor configuration modeling; the sensor configuration modeling specifically comprises the steps of configuring the ID and the installation address information of each tower inclination sensor (2) into platform software; distributing the configured sensors to an application scene of the power transmission line, and constructing a sensor information model and a model tree;
step two, data detection and transmission, wherein the terminal layer transmits the detected data of the inclination of the data iron tower and the rainfall, wind speed and wind direction information to the main station system layer;
step three, data storage, namely after the data sent by the wireless data transmission base station are received by the master station system layer, storing the data under the corresponding tower inclination sensor folders respectively;
step four, data processing and early warning, wherein the power transmission line state detection platform of the main station system layer compares the received iron tower inclination data with a set alarm threshold value, if the value of the iron tower inclination data is larger than the alarm threshold value, alarm information is sent out, otherwise, the alarm information is not sent out;
fifthly, displaying data, wherein when no alarm information exists, a display screen displays a desktop or a dialog box for a user to retrieve and view the data; when the alarm information exists, an alarm information dialog box can be automatically popped up on the display screen;
the fourth step of data processing and early warning specifically comprises,
step 401, setting alarm thresholds of tower inclination sensors 1 and 2 (2) at a power transmission line state detection platform of a main station system layer as D1, setting alarm thresholds of tower inclination sensors 3 and 4 (2) as D2, and setting alarm thresholds of tower inclination sensors 5 and 6 (2) as D3;
step 402, the power transmission line state detection platform acquires stored iron tower inclination data M1, M2,3 and 4 transmitted by the tower inclination sensor (2), and iron tower inclination data M5, M6 transmitted by the tower inclination sensor (2); drawing a graph of inclination trend change according to the real-time data of each tower inclination sensor (2), and simultaneously comparing the data with corresponding warning threshold data;
step 403, if M1 and M2 are smaller than D1, M3 and M4 are smaller than D2, and M5 and M6 are smaller than D3, judging that the whole iron tower is in good state;
step 404, if the M1 and the M2 are larger than D1, the M3 and the M4 are larger than D2, the M5 and the M6 are also larger than D3, and the inclination directions are consistent, judging that the whole iron tower has a dumping danger, and sending out alarm information; if M5 and M6 are both larger than D3 and the inclination directions are consistent, M1 and M2 are both smaller than D1, and M3 and M4 are both smaller than D2, judging that the upper part of the iron tower is at risk of breakage or damage; if M5 and M6 are both larger than D3 and the inclination directions are inconsistent, M1 and M2 are both smaller than D1, and M3 and M4 are both smaller than D2, the upper part of the iron tower is judged to be distorted, and alarm information is sent out; if M3 and M4 are both larger than D2, M5 and M6 are both larger than D3, and the inclination directions are consistent, and meanwhile M1 and M2 are both smaller than D1, judging that the middle upper part of the iron tower is at risk of breaking, and sending out alarm information; if more than one pair of data in the three pairs of data M1, M2, M3, M4, M5 and M6 reaches or continuously exceeds twice of the corresponding alarm threshold value, judging that the iron tower overturns, and sending alarm information;
and 405, counting the received data, and automatically drawing a statistical chart and a statistical report according to the statistical data.
