Embodiment
Below in conjunction with figure and preferred embodiment, its embodiment of automatic identification equipment, structure, feature and the effect thereof of the sensor that foundation the present invention is proposed describe in detail as the back:
Referring to accompanying drawing, the automatic identification equipment of sensor, by sensor 1, analog input unit 2, arithmetic element 3, the automatic recognition rule of sensor storehouse 4, sensor failure decision rule storehouse 5, sensor recognition unit 6, sensor information display unit 7 is formed, the output terminal of sensor 1 is connected with the input end of analog input unit 2, the input end of the output termination arithmetic element 3 of analog input unit 2, arithmetic element 3, the output terminal in the automatic recognition rule of sensor storehouse 4 and sensor failure decision rule storehouse 5 is connected with the input end of sensor recognition unit 6, and the output terminal of sensor recognition unit 6 is connected with sensor information display unit 7 input ends.
Sensor 1 is 1～16.
Its principle of work is as follows:
(1) collect the sampled value of each sensor 1, hits should get 10～20, and the sampling period should get 0.5～5 second;
(2) sampled value of each sensor is done the Characteristic Extraction computing respectively through arithmetic element 3, the characteristic quantity of extraction has: arithmetic mean, and variance, variation range, data are to 1,2,3,4 order derivatives of time, the cycle of fluctuation of data, frequency domain characteristic, correlativity; The value volume and range of product of the characteristic quantity that need extract is different because of the difference of automaton, is determined by built-in automatic recognition rule storehouse 4;
(3) to the characteristic quantity of each sensor through the sensor recognition unit 6 judgement computing that compares respectively, comparison judges that the input information of computing is: the characteristic quantity of each sensor, type and purposes, comparison judges that the foundation of computing is the automatic recognition rule of sensor storehouse 4, and comparison judges that the output decision-making of computing is each type of sensor, purposes and the input port that is used for automaton thereof;
