| description | The invention provides a redundancy monitoring method and system for monitoring the temperature of a stuffing box of a pump station. The method comprises the following steps: adopting a temperature sensor of a predefined measurement mechanism in each measurement channel; calculating a monitoring value of the measurement channel at the current moment based on a historical measurement value before the current moment; according to the sequence of the historical monitoring values of each measurement channel before the current moment, calculating a threshold value for judging the measurement abnormal value of the measurement channel at the current moment; if the absolute value of the difference value between the monitoring value of the measurement channel at the current moment and the mean value of the sequence of the historical monitoring values is greater than a threshold value, abandoning the monitoring value of the measurement channel to obtain a correct monitoring value of the measurement channel; and weighti |
