1. but the Weighing method of the belted electronic balance of self check, it is characterized in that, the weighing device that forms belted electronic balance with plural weighing carrier roller (3), each weighing carrier roller supports with two above LOAD CELLS (5), the signal transmission line (8) that each LOAD CELLS is passed through alone respectively is connected with PLC (7), PLC (7) directly obtains the output signal of weighing of each LOAD CELLS, simultaneously each weighing carrier roller and LOAD CELLS is carried out Real-Time Monitoring and diagnosis in weighing process;

  • Pattern by many carrying rollers when normally weighing is measured;

    PLC carry out through the weight signal after A/D conversion Real-Time Monitoring, identification, diagnosis, grouping, relatively after, carry out with rate signal from motor or belt the weight that integral operation calculates material;

    During diagnosis, weighing device is processed by two above single mount roller die formulas, each weighing carrier roller is measuring stick each other, when the signal of the signal of a LOAD CELLS and other LOAD CELLS relatively after, during less than or equal to the error set, according to the pattern of many carrying rollers, signal is carried out normal process in error;

    In error during greater than the error set, load cell signal to same weighing carrier roller and other weighing carrier roller the same side contrasts in twos, when the signal errors of the signal of one of them LOAD CELLS and other LOAD CELLS during greater than the error set, judge that namely this road LOAD CELLS has fault, weighing carrier roller to fault LOAD CELLS place stops computing, at this moment, belted electronic balance automatically switches to single mount roller or many carrying rollers quantitative model, and control panel shows out of order LOAD CELLS;

    When the signal errors of the signal of two LOAD CELLS wherein and other LOAD CELLS greater than the error of setting, judge that namely these two LOAD CELLS have fault, weighing carrier roller to fault LOAD CELLS place stops computing, at this moment, belted electronic balance automatically switches to single mount roller or many carrying rollers quantitative model, and control panel shows out of order LOAD CELLS;

    Greater than the error of setting, control panel shows overproof signal when the signal errors of the signal of half LOAD CELLS and other LOAD CELLS.
