At present, the most common express dimension measurement mode is manual detection. This method is inefficient, costly and has low accuracy for irregular objects. Meanwhile, some automatic object size measuring methods based on a camera and structured light exist in the market, but the detection results obtained by the measuring methods are greatly influenced by the color of the object, and when the color of the object is similar to the color of the conveyor belt, the outline of the object cannot be respectively obtained easily, so that errors are caused.
Some binocular camera-based automatic object size measuring methods exist in the market, and have the following problems: the shape of an object is required, the maximum cross section of the uppermost plane of the object needs to be ensured, and the problem is caused because the common camera has the characteristic of imaging the size of the object, and the method is not suitable for measuring the size of the irregular object.
Some automatic irregular object size measuring methods based on infrared gratings exist in the market, and the methods have the following problems: the measuring speed is not high, and the maximum speed is basically lower than 0.5 m/s. The speed of the whole logistics production line is generally more than 0.5m/s, so when the methods are used for measuring the size of the object, a deceleration belt is used for decelerating, and a conveyor belt is used for accelerating after the measurement is finished, so that the cost is increased, the efficiency of the whole logistics production line is reduced, and unstable factors can be increased.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
First embodiment
An embodiment of the present invention provides a dimension measuring apparatus 100 for measuring a volume of an object. Referring to fig. 1 and fig. 2, a schematic structural diagram of a dimension measuring apparatus 100 according to an embodiment of the invention is shown. The dimension measuring apparatus 100 includes two conveyor belts 110, a first echelette grating detector 120, a second echelette grating detector 130, an industrial personal computer 150, and an encoder 140. The first echelette detector 120 is horizontally disposed between the two conveyor belts 110, and the second echelette detector 130 is vertically disposed on the conveyor belts 110. Referring to fig. 3, a block diagram of a circuit structure of the dimension measuring apparatus 100 according to an embodiment of the invention is shown. The first echelette grating detector 120, the second echelette grating detector 130 and the encoder 140 are all electrically connected with the industrial personal computer 150.
Wherein both conveyor belts 110 are used for transporting the items to be conveyed. It should be noted that, in the present embodiment, the shape of the article to be conveyed is not limited at all, and may be regular or irregular.
In addition, a gap exists between the two conveyor belts 110, and the first echelette detector 120 is disposed in the gap. The first echelette detector 120 includes a transmitter and a receiver, which are respectively disposed at upper and lower sides of the conveyor 110 and are oppositely disposed through the gap.
The transmitter is used for emitting infrared light, and the receiver outputs an alarm signal once any object blocks more than two adjacent light beams emitted by the transmitter for more than 30 ms.
Thus, the first echelette detector 120 is configured to collect position information of the to-be-conveyed item located on the conveyor belt 110 at a preset first frequency and transmit the position information to the industrial personal computer 150.
It will be appreciated that when the article to be conveyed moves into the detection range of the first echelette detector 120 as the conveyor belt 110 moves, the emitter is blocked, thereby enabling the first echelette detector 120 to collect the positional information of the article to be conveyed. By collecting the position information according to the preset first frequency, the data collected by the first ir grating detector 120 can be reduced, so as to further increase the refresh rate of the first ir grating detector 120 or increase the transmission rate of the conveyor 110, thereby increasing the detection efficiency.
It should be noted that, because the shape of the article to be conveyed is not fixed, the shielding position of the article to be conveyed to the first echelette grating detector 120 is also different, so that the position information acquired at different time points is also different, and therefore, the cross-sectional shape of the article to be conveyed can be reflected by integrating all the position information. In addition, the position information includes a relative position of the object to be conveyed with respect to the first echelette detector 120.
The encoder 140 is disposed on the conveyor 110, and is configured to record an actual displacement value of the conveyor 110 in each time period corresponding to the first frequency according to the first frequency and transmit the actual displacement value to the industrial personal computer 150.
It can be understood that the conveyor belt 110 is not always in a constant speed state, and therefore, the encoder 140 may collect an actual displacement value of the conveyor belt 110 in each time period corresponding to the first frequency, and transmit the actual displacement value to the industrial computer 150, so that the industrial computer 150 corrects the position information according to the actual displacement value.
The industrial personal computer 150 is used for determining the side length of the external rectangle of the horizontal section of the object to be transmitted based on the position information.
Specifically, the industrial personal computer 150 is configured to determine a plurality of position coordinates of the item to be conveyed based on the position information. In a preferred embodiment, the acquired theoretical displacement of the conveyor belt 110 in the time is used as the ordinate, and the position information is used as the abscissa.
It should be noted that when the conveyor belt 110 moves at a constant speed, the displacement value of the conveyor belt 110 during the time can be known through the pre-stored speed of the conveyor belt 110.
However, in practical applications, it is impossible to maintain the conveyor 110 in a constant-speed operation state in real time, and thus the industrial personal computer 150 is also used to correct the position coordinates based on a plurality of actual displacement values. Specifically, a straight line parallel to the x-axis is made with the actual displacement value as an abscissa, and the position coordinate within the error range is corrected based on the straight line. For example, the position coordinate far from the straight line may be eliminated, or the position coordinate near the straight line may be translated, so that the y coordinate of the position coordinate is the actual displacement value.
The industrial personal computer 150 is further configured to calculate a plurality of first distance parameters based on each position coordinate and a preset first equation; and calculating a plurality of second distance parameters based on each position coordinate and a preset second formula.
Specifically, referring to fig. 4, two mutually perpendicular straight lines are drawn through each position coordinate, and an included angle between one of the straight lines and the x-axis is θ, then distances from the two straight lines to the origin respectively satisfy a predetermined first equation: a (θ) ═ y cos θ -x sin θ and a second equation: b (θ) ═ y × sin θ + x × cos θ, where (x, y) are position coordinates.
The industrial personal computer 150 is further configured to determine an area of an external rectangle of the horizontal cross section of the object to be transferred according to the plurality of first distance parameters and the plurality of second distance parameters.
Specifically, referring to fig. 5, after all the first distance parameters are calculated, the maximum first distance parameter and the minimum first distance parameter are determined from the first distance parameters; after all the second distance parameters are calculated, determining the maximum second distance parameter and the minimum second distance parameter from the second distance parameters; the industrial personal computer 150 determines the area of the circumscribed rectangle of the horizontal section of the object to be conveyed based on the difference value of the maximum first distance parameter and the minimum first distance parameter and the difference value of the maximum second distance parameter and the minimum second distance parameter.
It can be understood that the area of the circumscribed rectangle satisfies the equation: s (θ) ═ a (θ) × B (θ).
The industrial personal computer 150 is also used for calculating the side length of the external rectangle of the horizontal section of the object to be transmitted according to the area.
In a preferred embodiment, θ e [0,90 °), all the position coordinates and θ values are sequentially substituted into the formula S (θ) ═ a (θ) × B (θ), to obtain the θ value and the values a (θ) and B (θ) corresponding thereto when S (θ) is minimum.
The larger of the values a (θ) and b (θ) is the length of the circumscribed rectangle, and the smaller is the width of the circumscribed rectangle.
It should be further noted that, in the process of searching for the minimum area value, a coarse scanning and a fine scanning mode may be adopted, so that the searching efficiency may be greatly improved.
For example, since θ e [0,90 °), let θ step by 9 °, calculate corresponding S (θ) value according to each θ value until finding the minimum S (θ), where θ corresponding to S (θ) is θ _ min; and the step of theta is reset to be 0.9 degrees, and the like, and after the steps are repeated for multiple times, the accurate minimum area S (theta) and the corresponding theta value can be obtained.
The second echelette detector 130 is configured to collect height information of the object to be transferred according to a preset second frequency and transmit the height information to the industrial personal computer 150.
The second echelette detector 130 also includes a transmitter and a receiver, which are respectively disposed at the left and right sides of the conveyor belt 110 and are disposed opposite to each other.
It can be understood that when the belt conveyed article blocks the emitter of the second ir grating detector 130, the second ir grating detector 130 can be enabled to acquire the specific height of the article to be conveyed blocking the emitter, i.e. the height information.
By continuously acquiring the height information according to the second frequency, the highest position of the article to be conveyed can be continuously obtained. It should be noted that the second frequency may be smaller than the first frequency, and in a preferred embodiment, the second frequency is 10s, since the refresh frequency of the article to be conveyed has little effect on the measurement accuracy.
The industrial personal computer 150 is used for determining the height of the article to be conveyed according to the height information. Specifically, the industrial personal computer 150 is configured to use the largest value of the collected height information as the height of the article to be conveyed.
