Problems solved by technology

But at this stage, it is difficult to detect the weak changes of non-electrical signals. On the one hand, the measurement accuracy of non-electrical sensors is limited, and it is difficult to distinguish small signals and their changes. Simply using an amplifier circuit can easily lead to incorrect judgment results due to interference; on the other hand On the one hand, the abnormal parameters reflected by most non-electricity signals are time-varying transient parameters, which vary greatly with time. In the early stage of most hidden dangers, the transient parameters are normal most of the time, and the occurrence of abnormal events has Statistical significance: As time goes by, the frequency of occurrence becomes higher and higher, and the value gradually increases

Embodiment 1

[0026] refer to figure 1 , a non-electricity signal acquisition and monitoring method based on an integral algorithm proposed in this embodiment is used to detect temperature changes, which includes the following steps:

[0027] S1. Set a non-electrical sensor such as a temperature sensor to detect the temperature to be measured.

[0028] S2. Convert and restore the electrical signal output by the non-electrical quantity sensor into a non-electrical quantity signal parameter. Specifically, in this embodiment, the non-electricity sensor can be a rheostat temperature sensor, such as a thermistor. In this way, the temperature collected by the non-electricity sensor can be converted into a current signal by connecting the rheostat temperature sensor to the constant voltage source circuit. , according to the characteristics of the rheostat temperature sensor: the resistance value is linearly proportional to the temperature value, and the temperature value can be converted accordin...

[0049] refer to figure 2 , a non-electrical signal acquisition and monitoring method based on an integral algorithm proposed in this embodiment is used to detect stress changes, which includes the following steps:

[0050] S1. Set a non-electrical sensor such as a stress sensor to detect the stress to be measured.

[0051] S2. Convert and restore the output signal parameter value of the stress sensor to the stress value of the non-electrical signal parameter.

[0052] Specifically, in this embodiment, the selected non-electrical sensor is a resonant stress sensor, and the resonant frequency has a definite mathematical relationship with the detected stress, for example: the resonant frequency f 0 It is proportional to the square root of the stress F, so, through software calculation, the resonant frequency value is converted to the stress value.

[0053] S3. Integrate the non-electricity signal parameter or the change amount of the non-electricity signal parameter with respe...

Abstract

The invention discloses a method for collecting and monitoring non-electricity signals based on an integration algorithm, which comprises steps: S1 a non-electricity sensor is arranged; S2 output signals of the non-electricity sensor are converted and restored to be a non-electricity signal parameter; S3 the non-electricity signal parameter or the non-electricity signal parameter variable quantity are integrated for time to obtain non-electricity integral parameters of various time periods, and the non-electricity integral parameters of various time periods are stored; and S4 the situation of non-electricity signal parameters are judged according to the non-electricity integral parameters of various time periods, and the abnormity is monitored. The method for collecting and monitoring non-electricity signals based on the integration algorithm converts non-electricity detection into non-electricity integral parameter detection, are beneficial for accumulating and magnifying fine hidden troubles, and find out the hidden troubles to warm and treat in time in early middle stages, thereby preventing hidden troubles from being serious, preventing losing, and reducing risk.

Description

technical field [0001] The invention relates to the technical field of data measurement, in particular to a method for collecting and monitoring non-electrical signal parameters. Background technique [0002] Measurement is an important means to obtain various physical quantities and describe physical process parameters, so factories and research units need to measure many physical quantities when designing new mechanical structures, improving certain devices, and specifying process, in order to study their regularity, test Whether the design conforms to objective laws. Most of these measurements are non-electrical quantities, such as: mechanical quantities (displacement, vibration acceleration, speed, force, torque, strain, stress, etc.), thermal quantities (temperature, pressure, flow, etc.), chemical quantities (concentration, composition, humidity, pH, etc.). With the development of science and technology, new requirements are put forward for the accuracy and speed of ...
