Detailed Description
The following detailed description will be provided with reference to the accompanying drawings and embodiments, so that how to apply the technical means to solve the technical problems and achieve the corresponding technical effects can be fully understood and implemented. The embodiments and various features in the embodiments of the present application can be combined with each other without conflict, and the formed technical solutions are all within the scope of protection of the present application.
Example one
The invention provides a product quality detection method, please refer to fig. 1, which comprises the following steps:
step S110: and acquiring a detection signal of a target product detected by the radar equipment.
A radar apparatus is an electronic apparatus that detects a target using electromagnetic waves. The radar emits electromagnetic waves to irradiate the target and receives the echo of the target, so that information such as the distance from the target to an electromagnetic wave emission point, the distance change rate, the azimuth and the height is obtained. The radar type is divided into over-the-horizon radar, microwave radar, millimeter wave radar, laser radar and the like according to the radar frequency band, and the type of the radar equipment can be selected according to specific use requirements. For example, the radar apparatus may select a millimeter wave radar. The millimeter wave radar is a radar which operates in a millimeter wave band (millimeter wave) for detection, and generally, the millimeter wave refers to a frequency domain (wavelength is 1-10 mm) of 30-300 GHz. The millimeter wave radar has a small antenna aperture and narrow beams, and the narrow beams have high anti-interference performance. Therefore, the tracking and guiding precision is high, low elevation angle tracking is easy to carry out, multipath and clutter interference are resisted, high transverse resolution is achieved on a near-space target, high angular resolution is achieved on regional imaging and target monitoring, and small targets are easy to detect. In addition, the millimeter wave radar has a larger bandwidth, so that the millimeter wave radar has a high information rate, and the narrow pulse or broadband frequency modulation signal is easy to adopt to obtain the detailed structural characteristics of the target. In addition, the method has wide spectrum spreading capability, reduces multipath and clutter, enhances anti-interference capability, has high distance resolution, and is easy to obtain accurate target tracking and identification capability. The millimeter wave radar is easy to identify the target characteristics by using the target Doppler frequency characteristics.
The millimeter wave radar can be installed at a position where the assembly line can be detected, for example, the millimeter wave radar is installed at a position right opposite to the assembly line, so that the radar and a product to be detected on the assembly line are protected from being blocked by obstacles in the middle, and the radar is kept powered on and signals are normally transmitted and received. The position of the radar equipment is fixed relative to the ground and does not move along with the movement of the assembly line conveying belt. And the radar equipment needs to be installed in a place which does not influence the work of the assembly line, and does not need to be frequently disassembled. Thereby ensuring that the radar equipment can be conveniently maintained. Electromagnetic waves emitted by the millimeter wave radar can reflect back signals when meeting a target product obstacle in space, echo signals reflected by the target product in space are collected, intermediate frequency signals are output through ADC sampling after amplification, filtering, frequency mixing and analog-to-digital conversion, and the intermediate frequency signals are filtered through a distance difference method to obtain pure signals; the position information of the target product in the space can be obtained through target detection algorithms such as coherent and incoherent accumulation, DOA (direction of arrival) estimation and the like.
Step S120: and determining the parameters of the target product according to the detection signals.
Since the detection signal is obtained according to the reflection of the electromagnetic wave emitted by the radar device by the target product, the data related to the target product can be obtained from the detection signal, and the parameters of the target product can be determined according to the data.
Step S130: and detecting the quality of the target product according to the parameters of the target product and the parameters of a preset product.
The predetermined product is a product of known quality without problems, which is the same product as the target product. The quality of the target product can be judged by taking the preset product as a contrast. Specifically, parameters obtained by detecting the target product are compared with known parameters of a preset product, and if the comparison difference is large, the quality of the target product is considered to be unqualified. As an embodiment, if the size parameter a of the target product is obtained according to the detection signal, the size parameter of the preset product is B, the allowable error is C, and if a is greater than B + C, or a is less than B-C, the quality of the target product may be considered to be unqualified.
As another embodiment, when detecting the quality of the target product according to the parameters of the target product and the parameters of the preset product, a similarity value between the parameters of the target product and the parameters of the preset product may be calculated first. And if the similarity value is larger than a preset threshold value, determining that the target product is qualified in quality. And if the similarity value is smaller than or equal to the preset threshold value, determining that the target product is unqualified in quality. For example, in a boxed milk production workshop, a worker carelessly places a water cup on a milk production line, and can detect that the similarity of the shape and the size between a milk box and the water cup is smaller than a preset threshold value, and the judgment result is that the product is unqualified. If the milk box is inclined or placed in a tilted mode, the similarity between the appearance characteristics of the milk box and the characteristics of the preset products is smaller than a threshold value, unqualified milk boxes can be detected, and the phenomenon that the inclined or tilted products cannot accurately correspond to raw material outlets in a filling process to cause raw material waste and environmental pollution is avoided.
The parameters of the preset product can also be obtained by searching the data prestored in the database. It is to be understood that before the detection signal of the radar device detecting the target product is obtained, the parameters of the preset product may also be obtained in the following manner. Firstly, acquiring a detection signal of a radar device for detecting a preset product; and determining the parameters of the preset product according to the detection signal of the preset product. Through the embodiment, the parameters of the preset product can be accurately acquired, so that the quality of the target product can be accurately detected. For example, for a scene that a target product is not filled completely, an unfilled product meeting factory requirements can be selected and placed on a production line, information of the product is collected by a radar, product characteristic information is extracted through signal processing, and the product characteristic information is stored. And selecting the products which meet the factory requirements and are filled according to the scenes after the products are filled, placing the products on the production line, acquiring product information by using a radar, extracting product characteristic information and content characteristic information through signal processing, and storing the product characteristics and the content characteristic information. If the parameters of the preset product are acquired in this way, only one acquisition process is needed, and the acquired parameters of the preset product can be directly used during product quality detection. If the product that a assembly line was handled is unchangeable, for example, 500ml mineral water is handled all the time to this assembly line, and this mineral water packing shape size is unchangeable, then the parameter of the preset product that gathers before detecting product quality only need gather once and the storage can, need not carry out product quality detection work to the target product at every turn and all gather again, the radar can take out the information that has preserved automatically after the power-on work. If the production line originally treats 500ml of mineral water and then treats 300ml of mineral water, the parameters of the preset product corresponding to 300ml of mineral water need to be acquired again, namely, the characteristics of the qualified product are collected and stored again.
In summary, the present application provides a product quality detection method, including: acquiring a detection signal of a target product detected by radar equipment; determining parameters of the target product according to the detection signals; and detecting the quality of the target product according to the parameters of the target product and the parameters of a preset product. The target product is accurately detected through the radar equipment, the parameters of the target product are determined according to the detection signals obtained through detection, and the quality of the target product is detected according to the parameters of the preset product and the parameters of the target product. The radar technology is a non-contact sensor technology, and radar equipment transmits out electromagnetic waves and can reflect after hitting a target product in space, and in addition, different mediums absorb and reflect the electromagnetic waves differently, and detection signals obtained by detecting the target product through the radar equipment can be used for detecting the target product more comprehensively and accurately.
Example two
On the basis of the first embodiment, the present embodiment explains the method in the first embodiment through a specific implementation case.
In the product quality detection method, before a detection signal of a target product detected by the radar equipment is acquired, whether product loss and/or product position offset exist in a detection area on a production line or not can be judged through the following processes. Specifically, a detection signal of a target product detection area of the radar equipment is obtained; determining all products and positions thereof in the target product area according to the detection signal of the target product area; and determining whether product loss and/or product position offset exist in the target product area according to all products and positions thereof in the target product area and all products and positions thereof preset in the target product area.
The target product area is an area where products are placed on the assembly line, when the assembly line runs normally, a plurality of products can be detected in the target product area, the position relation between the radar device and the assembly line is known, the position of the products placed on the assembly line is also known, and for example, the interval between two adjacent products on the assembly line is L. The time for the radar to acquire the detection signal is also set, so that when the product passes through the radar, the position information of the product relative to the radar is also known, that is, all products and positions thereof preset in the target product area are known. And comparing the detected spatial position information of the product with the known spatial position information of the product, and if the comparison result shows that the product can be detected at the position of the preset product on the production line, determining that the product is free from missing and/or product position deviation. And if the comparison result shows that the product cannot be detected at the position of the preset product on the production line, the situation of product loss and/or product position deviation is considered to occur.
Taking a milk filling line as an example, since the filling machine works according to a specific law, assuming that the filling machine injects milk into the lower container every 1 second, the injection process line is stopped for 2 seconds, which requires that the products are placed at equal intervals, and the interval is the distance of 1 second of the conveyor belt running. Assuming that the distance between the radar device and the conveyor belt right in front of the radar device is 50cm, the product width is 5cm, the distance on the conveyor belt is 10cm, the radar detection range is 60cm in front and 20cm left and right, the radar can theoretically detect 3 targets at the position 50cm in front and has the distance of 10cm, and if the target information detected by the actual radar does not accord with the theoretical information, for example, only 1 target is detected in the range, or the detected targets have the distance of 20cm, the product is considered to be missing.
In addition, the millimeter wave radar is used for detecting the product quality, whether the product is missing or not and/or the product position is deviated can be detected, the idle articles or the damaged products on the assembly line can be detected, whether the products are filled in a qualified mode can be detected, the accuracy and the real-time performance of product quality detection are improved, labor and time cost are reduced, and therefore the millimeter wave radar has strong applicability.
EXAMPLE III
On the basis of the first embodiment, the present embodiment explains the method in the first embodiment through a specific implementation case.
As a first implementation manner, when determining the parameter of the target product according to the detection signal, the appearance characteristic parameter of the target product may be determined according to the detection signal.
Specifically, determining the appearance characteristic parameter of the target product according to the detection signal includes:
acquiring distance, azimuth angle and pitch angle information of the radar equipment and the target product according to the detection signal;
analyzing the distance, azimuth angle and pitch angle information to determine the size, shape and dimension of the target product.
As a second embodiment, when determining the parameter of the target product according to the detection signal, the content characteristic parameter of the target product may be determined according to the detection signal.
Specifically, the content characteristic parameter of the target product is determined according to the detection signal, and the method comprises the following steps:
and acquiring energy, power spectrum and polarization data of the target product according to the detection signal.
The signal that the millimeter wave radar transmitted is the toper in the space, and the product is in the irradiation range of millimeter wave radar completely, and the millimeter wave radar can obtain the distance of target, azimuth angle, pitch angle information simultaneously, because be the air around the product, the product can reflect the electromagnetic wave but the electromagnetic wave can not be reflected to the air around, according to the electromagnetic wave reflection area, combines the wide frequency spectrum characteristic and the high resolution characteristic of millimeter wave, extracts out product appearance characteristic, including size, shape, size, statistical characteristics etc.. The millimeter wave radar irradiates on the outer box of the product, a part of electromagnetic waves are reflected, and a part of electromagnetic waves can penetrate through the outer box. The content of the filled product is solid or liquid, the unfilled part of the content is air, the absorption and reflection of electromagnetic waves are greatly different due to different dielectric constants of the solid, the liquid and the gas, and the received reflected signals are processed to extract the characteristics of the content of the product.
And determining parameters for detecting the target product according to the detection signals, and detecting the quality of the product according to specific requirements. For example, in a milk production process, if a milk carton needs to be checked for quality before filling, the above-described first embodiment can be used for checking. If, after filling in the milk production, the milk box has already been filled with milk contents and is sealed, then the above-described second embodiment can be used for testing. It can be understood that the two embodiments may also be implemented in combination, for example, for a scene after the product is filled, similarity comparison may be performed between the detected appearance features and the corresponding preset appearance features, and if the similarity of all the features is greater than a threshold, the detected product is considered to be qualified in appearance; otherwise, the detected product is considered to be unqualified.
If the detected product is qualified in appearance, the product which is filled can be continuously detected. The millimeter wave radar irradiates on the outer box of the product, a part of electromagnetic waves are reflected, and a part of electromagnetic waves can penetrate through the outer box. The content of the filled product is solid or liquid, the unfilled part of the content is air, the absorption and reflection of electromagnetic waves are greatly different due to different dielectric constants of the solid, the liquid and the gas, and the received reflected signals are processed to extract the characteristics of the content of the product. And comparing the obtained content characteristics with the corresponding preset content characteristics. The corresponding content feature comparison means that the energy feature is compared with the energy feature, the power spectrum feature is compared with the power spectrum feature, and other features are analogized in the same way. If the similarity is larger than the threshold value, the detected product is qualified in filling, otherwise, the filling is unqualified. For example, in a cough syrup production line, a certain product cannot be filled, 200 ml of cough syrup should be filled according to regulations, however, only 70 ml of medicine is filled due to equipment failure, 130 ml of space above the container is air, the dielectric constant of the cough syrup is different from that of the air, so that the absorption and reflection of electromagnetic waves are different, the characteristics of the two reflected echo signals of the millimeter wave radar are different, and the product can be judged to be not filled qualified through comparison.
