Background
The electromagnetic wave material level switch is applied to process control and is used for monitoring whether materials exist in a pipeline, a storage bin or a hopper.
The electromagnetic wave material level switch comprises a transmitter and a receiver, wherein the transmitter and the receiver are arranged in a face-to-face mode. The transmitter transmits an electromagnetic wave signal, such as a microwave signal, and if the transmission path from the transmitter to the receiver is blocked by an object that absorbs or reflects microwave energy, the receiver will either fail to detect the microwave energy signal or receive a weak energy signal. The receiver judges whether a material is blocked between the transmitter and the receiver according to the existence or the strength of the received signal, and the relay is controlled to output to realize the purposes of indication and control.
In practical product application, the receiver judges whether a material blocks through a preset fixed threshold energy, and the threshold energy is set between the energy received when no material blocks and the energy received when the material blocks. When the received energy is higher than the threshold energy, judging that no material blocks; and when the received energy is lower than the threshold value, judging that the material is blocked.
In the actual material monitoring process, attachments, such as dust, may be formed on the transmitter, and the attachments absorb or reflect the energy emitted by the transmitter, so that the energy received by the receiver is reduced. It may happen that, as the usage time increases, the attachment formed on the emitter becomes more and more serious, and the energy emitted by the emitter is greatly absorbed or reflected, and when there is no material blocking, the energy received by the receiver may be lower than the threshold, and then a false judgment is generated, and a signal with material blocking is output. Therefore, the reliability of detecting the material by the electromagnetic wave level switch is reduced.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flow chart of a processing method of an electromagnetic wave level switch, which is applied to a receiver of the electromagnetic wave level switch, according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
step S11, detection data of electromagnetic wave energy is acquired.
The electromagnetic wave material level switch comprises: the present invention relates to a microwave energy transmission device, and more particularly to a microwave energy transmission device having a transmitter and a receiver, which are installed face to face, the transmitter transmitting an electromagnetic wave signal, for example, a microwave signal, and the receiver failing to detect the microwave energy signal or receiving a weak energy signal if a transmission path from the transmitter to the receiver is blocked by an object that absorbs or reflects microwave energy.
In practical application, the acquired detection data of the electromagnetic wave energy is detection data of the electromagnetic wave energy acquired by detecting the same material, and an initial threshold energy matched with the material is set in the receiver for the specific material, wherein the initial threshold energy is set between the energy received when no material blocks and the energy received when the material blocks. When the received energy is higher than the initial threshold energy, judging that no material is blocked; when the received energy is lower than the initial threshold energy, it is determined that there is a material blockage. Therefore, the detection data for detecting whether the materials exist or not is formed, and the electromagnetic wave energy is obtained.
In the actual material monitoring process, attachments, such as dust, may be formed on the transmitter, and the attachments absorb or reflect the electromagnetic wave energy transmitted by the transmitter, so that the electromagnetic wave energy received by the receiver is reduced. In the specific material monitoring process, the change of attachments on the transmitter, for example, the attachments are accumulated and increased gradually, and for example, the attachments are partially dropped due to vibration, so that the detection data of the electromagnetic wave energy detected by the receiver is changed continuously.
And step S12, acquiring the current threshold energy.
The receiver is provided with current threshold energy for comparing the received electromagnetic wave energy with the current threshold energy to judge whether the material is blocked. Aiming at specific materials, an initial threshold energy matched with the materials is preset in the receiver as a current threshold energy, and when the electromagnetic wave material level switch is initially applied, the current threshold energy is obtained to obtain the preset initial threshold energy.
It should be noted that, the sequential description of step S11 and step S12 in this application does not mean that, in practical application, step S11 must be executed first, and then step S12 must be executed. In practical applications, step S11 and step S12 are not sequentially executed.
And step S13, processing the current threshold energy according to the detection data.
The receiver processes the current threshold energy according to the acquired detection data of the electromagnetic wave energy, and the correlation between the detection data of the electromagnetic wave energy and the current threshold energy is established, so that the dynamic adjustment of the threshold energy of the receiver according to the detection data of the electromagnetic wave energy of the receiver is facilitated.
The procedure is described below with reference to specific examples for specific processing modes.
In an embodiment, as shown in fig. 2, fig. 2 is a schematic flowchart of the process of processing the current threshold energy according to the detection data according to an embodiment of the present application, and includes the following steps:
and S21, determining whether the current threshold energy needs to be adjusted according to the detection data.
In practical applications, for example, the material a is detected by using the above embodiment, for the material a, an initial threshold energy matched with the detection of the material a is set in the receiver, and during the detection of the material a, the detection data of the electromagnetic wave energy is obtained.
In an initial time period when the electromagnetic wave level switch is initially used, for example, the initial time period is several months, in the initial time period, no attached matter is formed on the emitter, the receiver is in a state without material blocking, or in a state with material blocking, the received electromagnetic wave energy is relatively stable, the initial threshold energy can be always used as the current threshold energy, that is, it is determined that the current threshold energy does not need to be adjusted according to the detection data.
In the above case, the user desires.
However, with the increasing time of practical use of electromagnetic wave level switches, it may happen that attachments, such as dust, are formed on the emitter, and the attachments absorb or reflect energy emitted by the emitter, so that the energy received by the receiver is reduced. Without material blocking, it is possible to have the energy received by the receiver trend closer to the initial threshold energy. An effective way to do this is to perform a regular manual cleaning process on the transmitter to remove the attachments, but in practice, once the electromagnetic wave level switch is used, there is a requirement for continuous monitoring over the years, and the regular manual cleaning process on the transmitter is not allowed, and thus, the regular manual cleaning process on the transmitter is not suitable in practice. Under the condition, when no material blocks, the energy received by the receiver changes towards the trend lower than the initial threshold energy, so as to avoid the generation of misjudgment, a signal with material blocking is output, and the initial threshold energy is determined to be required to be adjusted so as to obtain the new current threshold energy.
For how to determine whether the current threshold energy needs to be adjusted according to the detection data, in an embodiment, the following specific scheme is further provided:
the determining whether the current threshold energy needs to be adjusted according to the detection data includes:
according to the detection data, obtaining the change conditions of the electromagnetic wave energy detected when the material is blocked and the electromagnetic wave energy detected when the material is not blocked;
and determining whether the current threshold energy needs to be adjusted according to the change conditions of the current threshold energy and the current threshold energy.
In practical application, according to the detection data, the change conditions of the electromagnetic wave energy detected when the material is blocked and the electromagnetic wave energy detected when the material is not blocked are obtained. The change condition of the electromagnetic wave energy detected when the material is blocked and the change condition of the electromagnetic wave energy detected when the material is not blocked can be directly obtained according to the detection data of the electromagnetic wave energy. In this scheme, since the detection data includes the interference data, it may be determined from the interference data that the current threshold energy needs to be adjusted, which is obviously not desirable.
Therefore, the detection data of the electromagnetic wave energy needs to be processed to obtain more reliable characteristic data, and the change conditions of the electromagnetic wave energy detected when the material is blocked and the electromagnetic wave energy detected when the material is not blocked are obtained according to the characteristic data, so that the method is more reliable.
In a specific application, the detection data obtained in each period with the material blocking state can be used as a data selection range to correspondingly obtain characteristic data with the material blocking state, and each characteristic data with the material blocking state is a representative energy value obtained in each period with the material blocking state according to all energy values. For example, the minimum value of energy in the detected data obtained during each material blocking state, or the minimum point of change of the energy value, or the average value of the energy value is used as the characteristic data of the material blocking.
Similarly, a characteristic data without material blocking can be correspondingly obtained by using the detection data obtained during each period without material blocking as a data selection range, and each characteristic data without material blocking is a representative energy value obtained according to all energy values in each period without material blocking. For example, the maximum value of energy, or the maximum point of change in the energy value, or the average value of energy in the detection data obtained during each material-barrier-free state is used as the characteristic data of material-barrier-free state.
The following describes the obtaining of the characteristic data by taking fig. 3 as an example, fig. 3 is a schematic diagram of the electromagnetic wave energy detected by the receiver according to an embodiment of the present application, in fig. 3, the abscissa represents time, the ordinate represents energy values, the curve is a curve formed by detected electromagnetic wave energy, F represents a threshold energy line, G represents a positive return difference line, H represents a negative return difference line, according to the threshold energy line, the positive return difference line and the negative return difference line, it is determined that the AB section curve corresponds to detection data obtained in a material blocking state period, the AC section curve corresponds to detection data obtained in a material blocking state period below the negative return difference line, the BD section curve corresponds to detection data obtained in a material blocking free state period, and the BE section curve corresponds to detection data obtained in a material blocking free state period above the positive return difference line.
The characteristic data with material blockage obtained according to fig. 3 may be the energy minimum value in the data corresponding to the curve of the AB segment, or the minimum point of the change of the energy value. In practical application, the influence of noise spikes is considered, and the minimum value or the minimum point of the curve after filtering can be considered; alternatively, the average value of the data corresponding to the AC segment curve may be used.
Similarly, the characteristic data without material blockage obtained from fig. 3 may be the maximum energy value in the data corresponding to the BD segment curve, or the maximum point of the energy value change. In practical application, the influence of the noise spike is considered, and the maximum value or the maximum point of the curve after filtering is considered; alternatively, the average value of the data corresponding to the BE segment curve may BE used.
According to the scheme of the related embodiment, the characteristic data with material blockage and the characteristic data without material blockage are obtained, and then the change conditions of the electromagnetic wave energy detected with material blockage and the electromagnetic wave energy detected without material blockage are determined according to the characteristic data with material blockage and the characteristic data without material blockage, so that the determined change condition result is more reliable.
In one embodiment, the determining whether the current threshold energy needs to be adjusted according to the variation of the current threshold energy and the variation of the current threshold energy comprises:
in the two methods, if the change condition of one of the two methods meets a preset condition, the current threshold energy is determined to need to be adjusted; wherein the content of the first and second substances,
the preset conditions include:
the change in one of the above is: a change occurs; alternatively, the first and second electrodes may be,
the change in one of the above is: and changing the change quantity to reach a preset threshold ratio or a threshold value.
In the above embodiment, the preset condition is to determine that the current threshold energy needs to be adjusted, the preset condition is preset in the receiver, the receiver determines, according to the detected data of the electromagnetic wave energy, the change conditions of the electromagnetic wave energy detected when the material is blocked and the electromagnetic wave energy detected when the material is not blocked, and then determines whether the change conditions of the electromagnetic wave energy and the electromagnetic wave energy meet the preset condition, if so, it is determined that the current threshold energy needs to be adjusted, and if not, it is determined that the current threshold energy does not need to be adjusted.
The preset conditions include: the change in one of the above is: a change occurs. In practical applications, the characteristic data with material blockage and the characteristic data without material blockage obtained according to the related embodiments described above, and then the change conditions of the electromagnetic wave energy detected with material blockage and the electromagnetic wave energy detected without material blockage are obtained according to the characteristic data with material blockage and the characteristic data without material blockage.
When the electromagnetic wave level indicator detects the material, the material is in a material blocking state, or the material blocking state is not. Thus, the one of the changes may be the change of the electromagnetic wave energy detected when the material is blocked or the change of the electromagnetic wave energy detected when the material is not blocked.
For example, when the electromagnetic wave level gauge detects a material, the material is in a material blocking state, and according to characteristic data of material blocking, if the change condition of the detected electromagnetic wave energy when the material is blocked is changed to be close to the current threshold energy, the attachment formed on the emitter can be represented, and the attachment absorbs or reflects the energy emitted by the emitter, so that the energy received by the receiver is correspondingly reduced, the attachment is changed to be close to the current threshold energy, and the current threshold energy is determined to be required to be adjusted; or, if the change condition of the detected electromagnetic wave energy when the material is blocked is changed from the current threshold energy, the attachment formed on the transmitter can be represented to fall off, so that the energy received by the receiver is correspondingly increased, the change is carried out from the current threshold energy, and the need of adjusting the current threshold energy is also determined.
For another example, when the electromagnetic wave level gauge detects a material, the electromagnetic wave level gauge is in a non-material-blocking state, according to characteristic data without material blocking, if the change condition of the detected electromagnetic wave energy without material blocking is changed to approach the current threshold energy, an attachment can be represented on the emitter, the attachment absorbs or reflects the energy emitted by the emitter, so that the energy received by the receiver is correspondingly reduced, the change is performed to approach the current threshold energy, and the current threshold energy is determined to be required to be adjusted; or if the change condition of the detected electromagnetic wave energy is changed from the current threshold energy when no material is blocked, the attachment formed on the emitter can be represented to fall off, so that the energy received by the receiver is correspondingly increased, the change is carried out from the current threshold energy, and the need of adjusting the current threshold energy is also determined.
The variation for one of the above is: and changing the change quantity to reach a preset threshold ratio or a threshold value. Wherein, the above related embodiment has changed the one of the following cases: the change is explained, and the description is not repeated here. In the embodiment, the change amount which is changed is further set to reach the preset threshold ratio or threshold value, and the adjustment required for determining the current threshold energy is further limited, so that the adjustment frequency is more reasonable, and the adjustment is not performed when the change occurs, and the adjustment frequency is too high. In order to realize that the adjustment frequency is reasonable, in practical application, a user can specifically set a threshold value ratio or a threshold value according to own requirements so as to meet the self adjustment frequency requirements of the user.
Through the scheme of the embodiment, the requirement of adjusting the current threshold energy can be met under the condition of accumulation or falling of the attached crops on the emitter.
S22, if yes, adjusting the current threshold energy, and taking the adjusted threshold energy as the current threshold energy;
if not, keeping the current threshold energy unchanged.
According to the scheme of the embodiment, the receiver uses the detection data of the electromagnetic wave energy as a basis, when the current threshold energy is determined to be required to be adjusted, the receiver responds to the detection data of the electromagnetic wave energy to automatically adjust the threshold energy, so that the threshold energy for automatically and dynamically adaptively adjusting the receiver is facilitated to be realized, and the problem that attachments formed on the emitter absorb or reflect the electromagnetic waves emitted by the emitter when the threshold energy set by the receiver is a fixed value in the prior art is further overcome. Therefore, the reliability of material detection is improved.
In one embodiment, the adjusting the current threshold energy includes:
and according to the variation when one of the current threshold energies changes, adjusting the current threshold energy in the same variation trend.
In a specific application, the variation of one of the electromagnetic wave energy detected with the material blocking and the electromagnetic wave energy detected without the material blocking may be a ratio variation, such as a percentage, or a specific value variation.
The adjustment of the same trend of change for the current threshold energy means that the adjustment of the same trend of change is realized by taking the variation when one of the threshold energies changes as an adjustment amount and taking the trend of change (for example, rising or falling) of the one of the threshold energies as an adjustment trend.
For example, when the electromagnetic wave level gauge detects a material, the electromagnetic wave level gauge is in a material blocking state, according to characteristic data of material blocking, if the change condition of the detected electromagnetic wave energy when the material blocking is obtained is to be changed to be close to the current threshold energy, attachment can be represented on the emitter, the attachment absorbs or reflects the energy emitted by the emitter, so that the energy received by the receiver is correspondingly reduced, the current threshold energy is changed to be close to, the current threshold energy is determined to be required to be adjusted, and the current threshold energy is adjusted according to the change quantity changing to be close to the current threshold energy in the same change trend. Or if the change condition of the detected electromagnetic wave energy is changed from the current threshold energy when the material is blocked, the attachment formed on the emitter can be represented to fall off, so that the energy received by the receiver is correspondingly increased, the change is carried out from the current threshold energy, the adjustment of the current threshold energy is determined, and the adjustment of the same change trend is carried out on the current threshold energy according to the change quantity of the change from the current threshold energy.
For another example, when the electromagnetic wave level gauge detects a material, the electromagnetic wave level gauge is in a non-material-blocking state, according to characteristic data without material blocking, if the change condition of the detected electromagnetic wave energy without material blocking is changed to approach the current threshold energy, it can be characterized that an attachment is formed on the emitter, the attachment absorbs or reflects the energy emitted by the emitter, so that the energy received by the receiver is correspondingly reduced, the attachment changes to approach the current threshold energy, it is determined that the current threshold energy needs to be adjusted, and the current threshold energy is adjusted according to the change quantity changing to approach the current threshold energy in the same change trend. Or if the change condition of the detected electromagnetic wave energy is changed from the current threshold energy when no material is blocked, the attachment formed on the emitter can be represented to fall off, so that the energy received by the receiver is correspondingly increased, the change is carried out from the current threshold energy, the adjustment of the current threshold energy is determined to be needed, and the adjustment of the same change trend is carried out on the current threshold energy according to the change quantity of the change from the current threshold energy.
Through the scheme of the embodiment, the current threshold energy of the receiver can be dynamically and adaptively adjusted, and the current threshold energy adjusting requirement under the condition of accumulation or falling of the attached crops on the transmitter is met.
Through the scheme of the embodiment, the problem that the energy detected by the material blocking and material blocking is too close to the current threshold energy can be solved, and the reliability of material detection is improved.
For the processing of the current threshold energy according to the detection data, the present application further provides another embodiment, specifically:
the processing the current threshold energy according to the detection data includes:
and generating a visual analysis model of the current threshold energy according to the detection data and the current threshold energy, and displaying the visual analysis model on a display screen of the receiver so that a user can perform visual analysis on whether the current threshold energy is adjusted or not according to the visual analysis model displayed on the display screen of the receiver.
According to the embodiment, the visual analysis model is formed on the display screen of the receiver, visual analysis requirements can be provided for a user, the user can determine whether to adjust the current threshold energy according to own judgment according to the visual analysis model, and if the user judges that the current threshold energy needs to be adjusted, the current threshold energy can be manually adjusted by performing key setting operation on the receiver.
In one embodiment, the generating and displaying a visual analysis model of the current threshold energy on a display screen of the receiver according to the detection data and the current threshold energy comprises:
according to the detection data, energy lines corresponding to electromagnetic wave energy when the material is blocked and electromagnetic wave energy when the material is not blocked are generated, and
forming a threshold energy point according to the current threshold energy;
and displaying the energy lines corresponding to the two energy lines and the threshold energy point on a display screen of the receiver so that a user can determine the change condition of the energy lines corresponding to the two energy lines relative to the threshold energy point.
In practical application, according to the detection data, energy lines corresponding to electromagnetic wave energy when the material is blocked and electromagnetic wave energy when the material is not blocked are generated. The energy lines corresponding to the electromagnetic wave energy when the material is blocked and the electromagnetic wave energy when the material is not blocked can be generated directly according to the detection data of the electromagnetic wave energy. Under the scheme, interference data may exist in the detection data of the electromagnetic wave energy, and energy lines corresponding to the electromagnetic wave energy when the material is blocked and the electromagnetic wave energy when the material is not blocked, which are obtained by the method, may have a variation trend belonging to an interference item, which is obviously not an expected situation for a user to manually judge whether to adjust the current threshold energy.
Therefore, the detection data of the electromagnetic wave energy needs to be processed to obtain more reliable characteristic data, and the change conditions of the electromagnetic wave energy detected when the material is blocked and the electromagnetic wave energy detected when the material is not blocked are obtained according to the characteristic data, so that the method is more reliable.
Regarding processing the detection data of the electromagnetic wave energy to obtain more reliable characteristic data, detailed descriptions have been given in the above related embodiments of the present application, and are not repeated herein.
According to the scheme of the related embodiment, the characteristic data with material blocking and the characteristic data without material blocking are obtained, and then the energy lines corresponding to the electromagnetic wave energy with material blocking and the electromagnetic wave energy without material blocking are generated according to the characteristic data with material blocking and the characteristic data without material blocking, so that the displayed visual analysis model is more reliable, namely, the result of determining the change condition of the energy lines corresponding to the material blocking and the electromagnetic wave energy without material blocking relative to the threshold energy point by a user is more reliable.
Based on the scheme of the visualization analysis model, the application also provides a further scheme below.
In one embodiment, the method further comprises:
acquiring threshold energy manually input by a user;
determining a threshold energy manually input by a user as the current threshold energy.
According to the embodiment, a user analyzes whether the current threshold energy is adjusted or not according to the visual analysis model, when the user determines that the current threshold energy needs to be adjusted, the user can input the threshold energy through the related keys on the receiver, after the receiver obtains the threshold energy input by the user, the threshold energy manually input by the user is determined as the current threshold energy, and the material is detected by taking the threshold energy manually input by the user as the current threshold energy.
In one embodiment, the method further comprises:
and if the current threshold energy is adjusted, forming a threshold energy line according to the current threshold energy before and after adjustment, and displaying on a display screen of the receiver.
According to the embodiment, after the current threshold energy is adjusted, the current threshold energy before and after adjustment forms a threshold energy line, an automatically-changed historical threshold energy curve can be displayed on a display screen of the receiver, and a user can analyze the historical condition of the accumulation or falling condition of the attached crops on the transmitter according to the automatically-changed historical threshold energy curve.
In practical applications, the receiver of the above-mentioned related embodiment self-adjusts the threshold energy according to the detection data, and the receiver of the above-mentioned related embodiment self-generates the visualization model according to the detection data and the current threshold energy, and displays the visualization model on the display screen of the receiver.
Alternatively, the two schemes may be combined in a product, for example, a product uses both the receiver according to the above-mentioned related embodiment scheme to adaptively adjust the threshold energy according to the detection data, and the receiver according to the above-mentioned related embodiment scheme generates a visualization model according to the detection data and the current threshold energy, and displays the visualization model on the display screen of the receiver. Under the normal condition, the receiver self-adapts to and adjusts the threshold energy according to the detection data, and meanwhile, when the user visually checks, the user considers that the threshold energy is further adjusted, and the user can input the threshold energy by himself to adjust the current threshold.
