Detailed Description
The present application will be described in further detail with reference to fig. 1-12. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The embodiment of the application discloses a method for detecting the running state of a drainage tube. Referring to fig. 1, a method for detecting the operation state of a drainage tube is based on an ultrasonic module 2, a temperature measuring module 3, an infrared correlation module 4 and a controller 5.
As shown in fig. 1 and 2, the ultrasonic module 2 includes a plurality of ultrasonic transmitters 21 and a plurality of ultrasonic sensors 22, wherein the plurality of ultrasonic transmitters 21 are fixedly connected to one end of the drainage tube 1 far away from the drainage site for generating ultrasonic waves on the drainage tube 1, and the plurality of ultrasonic sensors 22 are fixedly connected to the drainage tube 1 and uniformly distributed along the length direction of the drainage tube 1. One ultrasonic emitter 21 emits ultrasonic waves of a fixed set frequency, the other ultrasonic emitter 21 emits ultrasonic waves of another fixed set frequency, and the transmission process is different from one ultrasonic emitter to another ultrasonic emitter. The ultrasonic wave propagates from the output of the drainage tube 1 to the drainage position, and the longer the propagation distance is, the greater the amplitude attenuation of the ultrasonic wave is, and the amplitude attenuation of the ultrasonic wave of different frequencies is different at the same position. If there is no abnormal portion on the drainage tube 1, the attenuation of the ultrasonic amplitude at each portion of the drainage tube 1 in the longitudinal direction is uniform, and if there is an abnormal portion such as a tube blocking or a tube folding on the drainage tube 1, the attenuation of the ultrasonic amplitude at the abnormal portion becomes uneven or abrupt.
As shown in fig. 8, the temperature measuring module 3 is provided in plurality and fixedly connected to the drain tube 1 and uniformly distributed along the length direction of the drain tube 1. The measurement part of the temperature measurement module 3 is directly attached to the drainage tube 1 or conducts heat through a heat conducting component. Both the ultrasonic module 2 and the temperature measuring module 3 can be used for a transparent drainage tube 1 or an opaque drainage tube 1. The temperature measurement module 3 is uniformly arranged on the drainage tube 1, can collect temperature data at multiple points, and can collect temperature data of all parts on the drainage tube 1. When multi-point position acquisition of temperature data is carried out, an analog temperature sensor or a digital temperature sensor is sequentially arranged on the drainage tube 1, the digital temperature sensor can adopt DS18B20, and different positions can be used for measuring different temperature data. If the temperature data of all the parts on the drainage tube 1 are collected, an infrared temperature-sensing camera can be adopted to shoot a thermal image on the drainage tube 1, and the temperature data of the drainage tube 1 and all the parts of the drainage tube 1 are extracted from the thermal image by using the existing image algorithm.
As shown in fig. 5, the infrared correlation modules 4 are provided with a plurality of groups, are adhered to the transparent drainage tube 1 through transparent colloid, and are uniformly distributed along the length direction of the drainage tube 1. The infrared correlation module 4 can also be fastened on the transparent drainage tube 1 by transparent adhesive tape or opaque adhesive tape. The infrared light emitted by the infrared correlation module 4 passes through the transparent drainage tube 1, if the liquid in the drainage tube 1 is full and stable, the light transmittance or the light loss of the infrared light passing through the drainage tube 1 is unchanged, and if the drainage tube 1 is hollow, the light transmittance or the light loss is also unchanged. If the drainage tube 1 is in an abnormal state such as tube blocking or tube folding, the light transmittance or light loss at the abnormal portion and in a certain distance range around the abnormal portion will change.
Returning to fig. 1 and 2, the controller 5 is electrically connected with the ultrasonic module 2, the infrared correlation module 4 and the temperature measurement module 3, and the controller 5 controls the working states of the ultrasonic module 2, the infrared correlation module 4 and the temperature measurement module 3, receives the data of the ultrasonic module 2, the infrared correlation module 4 and the temperature measurement module 3, and calculates. The controller 5 is also connected to a display 6, and the result of the calculation is displayed by the display 6. The display 6 can adopt a display screen or a display light bar arranged on the drainage tube 1, the display light bar can be an LED light bar, and the positions of the light beads on the display light bar correspond to the positions of all parts on the drainage tube 1.
As shown in fig. 3, the method comprises the steps of:
the controller 5 activates the ultrasonic emitter 21 to emit ultrasonic waves of a first preset frequency to the drainage tube 1, and also activates the other ultrasonic emitter 21 to emit ultrasonic waves of a second preset frequency to the drainage tube 1. The ultrasonic waves of the two preset frequencies are not transmitted at the same time, so that the interference influence on the acquisition work of the ultrasonic sensor 22 caused by the simultaneous existence of the ultrasonic waves of the two preset frequencies is avoided.
The controller 5 acquires a plurality of amplitude data of the corresponding part on the drainage tube 1 in real time through a plurality of ultrasonic sensors 22, the ultrasonic sensors 22 acquire ultrasonic waves transmitted on the drainage tube 1 and convert the amplitudes of the ultrasonic waves into corresponding voltage values and output the voltage values, and the controller 5 acquires the voltage values and converts the voltage values into the corresponding amplitudes according to a preset formula to generate the amplitude data.
And at a preset time point, calculating a position corresponding to the amplitude variation extremum according to a plurality of amplitude data acquired in real time, and generating first amplitude variation extremum position data. For example, ten ultrasonic sensors 22 are arranged on the drainage tube 1, ten amplitude data are generated at the same time, jump values in the ten amplitude data are calculated as amplitude variation extremum, wherein the jump amount needs to be compared with a preset jump value, if the jump value is compared, the calculation can be continued, and otherwise, no jump exists. If the comparison is passed, an amplitude variation extremum can be calculated, and first amplitude variation extremum position data is generated according to the position of the drainage tube 1 part corresponding to the amplitude variation extremum.
During a time period of a preset duration, the single ultrasonic sensor 22 generates a set of amplitude data during the time period, and amplitude variation extremum data and amplitude variation cumulative data are calculated. For example, ten ultrasonic sensors 22 are disposed on the drainage tube 1, in the same time period, each ultrasonic sensor 22 generates ten amplitude data, that is, ten sets of amplitude data, and there are hundred amplitude data in total, and a jump value of each set of the ten sets of amplitude data is calculated as an amplitude variation extremum, where the jump amount needs to be compared with a preset jump value, if the comparison is passed, the calculation can be continued, otherwise, no jump exists. If the comparison is passed, an amplitude variation extremum can be calculated, and amplitude variation extremum data can be generated according to the position of the drainage tube 1 part corresponding to the amplitude variation extremum. Each group of amplitude data also corresponds to amplitude variation accumulated data. That is, the plurality of ultrasonic sensors 22 correspond to the plurality of amplitude change extremum data and the plurality of amplitude change integrated data.
Calculating an amplitude variation extremum position according to the plurality of amplitude variation extremum data to generate second amplitude variation extremum position data, wherein the calculating method comprises the following steps: and taking weighted average values of the amplitude variation extremum data to obtain final data as the amplitude variation extremum data, obtaining the corresponding position as the amplitude variation extremum position, and correspondingly matching the amplitude variation extremum position data according to the amplitude variation extremum position. Then, according to the plurality of amplitude variation accumulation data, calculating an amplitude accumulation extremum position and generating third amplitude variation extremum position data, wherein the calculating method comprises the following steps: and taking a weighted average of the plurality of amplitude variation accumulation data to obtain final data as amplitude accumulation extremum data, acquiring a corresponding position as an amplitude accumulation extremum position, and correspondingly matching the amplitude accumulation extremum position data according to the amplitude accumulation extremum position.
