First embodiment

In order to implement security control on a product and improve the management security performance of an enterprise on the product, this embodiment provides an article control target setting method, and referring to fig. 3, fig. 3 is a schematic flow diagram of the article control target setting method according to the first embodiment of the present invention, where the method includes:

s301, setting a marker chart on the current to-be-controlled article according to a pattern setting strategy;

notably, the pattern setting strategy includes: the method comprises the steps of setting h marking graphs (h is more than or equal to 2) on an article, setting a reference point for each marking graph, determining a reference straight line which extends from the reference point as a starting point and has a length of L0, and determining a marking straight line which intersects with the end point of the reference straight line and is perpendicular to the reference line, wherein the marking straight line is divided into i marking line segments (i is more than or equal to 2), and cosine value ranges corresponding to the head point and the tail point of each marking line segment represent a numerical sequence. The cosine value is obtained by taking a reference straight line as an adjacent edge and respectively taking a connecting line of a starting point and head and tail points of the marking line segment as a bevel edge.

S302, determining a numerical sequence of management serial numbers of the articles;

s303, extracting elements corresponding to each marker map from the management sequence number numerical sequence according to the corresponding relation between each preset marker map and the elements of the management sequence number numerical sequence to form a numerical sequence to be represented by each marker map;

and S304, respectively setting identification points on the marking line segments corresponding to the marking graphs according to the numerical value sequences represented by the marking graphs and the preset marking line segment cosine value ranges and numerical value sequence mapping relations of the marking lines.

In this embodiment, the elements of the management number value sequence refer to the values constituting the management number value sequence, which may constitute a plurality of small value sequences for representing each identifier map. For example, there are three identification diagrams, the management serial number value sequence is binary number 110011000, the elements thereof are 9 in sequence of 1, 0, 1, 0, and the value sequence to be characterized of each identification diagram composed of the values of the elements is 110, 011, 000 in sequence.

It should be understood that the number of elements of the small numerical sequence of the numerical composition of the elements may be predetermined, for example, the numerical sequence shown in the previous example may also be that each element is a numerical sequence, and the small numerical sequence of the numerical composition shown in the previous example has 9 elements. It should also be understood that the management number value sequence includes, but is not limited to, the binary numbers shown in the previous examples, and may also be a value sequence in octal, decimal, hexadecimal, etc. It should be noted that the elements of the numerical sequence refer to the respective numerical values constituting the management sequence number numerical sequence, and the numerical sequence to be characterized by the identifier map is determined by the numerical values and the number of the elements.

In this embodiment, the following relationship exists between the system number adopted by the management sequence number value sequence and the number of marking line segments included in each marking map:

the management sequence number numerical sequence is a k-bit m-system sequence, the number n of marking line segments contained in each marking graph is the same, and the value of n is greater than or equal to m to the power of (k/h). For example, if the management sequence number value sequence is binary number 110011000, k equals 9, m equals 2, and h equals 3, each identifier map contains at least 8 closed circles.

It should be understood that, at this point, the number of elements of the numerical sequence to be characterized per identifier map is k/h. Still in the above example, where the binary sequence is taken as an example, k is equal to 9, and h is equal to 3, the number of elements of the numerical sequence to be characterized in each tag map is 3.

It should be noted that, in this embodiment, the correspondence relationship between each tag map and the element of the management sequence number value sequence is:

according to the sequence from big to small of the figure number of each identification figure, the identification figures respectively correspond to the lower element to the upper element of the management number value sequence in sequence, or respectively correspond to the upper element to the lower element of the management number value sequence in sequence. The element bit number corresponding to each identification graph is k/h bit, and the graph number is a unique identification number set for each identification graph.

For example, the management number value sequence is a binary number 110011000, there are three value sequences to be characterized, the identifier map has three

identifier maps

1, 2 and 3, and at this time, the elements 0, 0 and 0 can be extracted according to the correspondence between the identifier maps 1 and the elements of the management number value sequence to form a value sequence 000 to be characterized; extracting

elements

0, 1 and 1 according to the corresponding relation between the identifier figure 2 and the elements of the management sequence number numerical sequence to form a numerical sequence 011 to be characterized; according to the corresponding relationship between the identifier FIG. 3 and the elements of the management sequence number value sequence, elements 1, 0 are extracted to form the value sequence 110 to be characterized.

For another example, the management number value sequence is binary number 110011000, there are three value sequences to be represented, the identifier map has three

identifier maps

1, 2 and 3, and at this time, corresponding

elements

1, 1 and 0 can be extracted according to the correspondence between the identifier maps 1 and the elements of the management number value sequence to form the value sequence 110 to be represented; extracting

corresponding elements

0, 1 and 1 according to the corresponding relation between the identifier figure 2 and the elements of the management serial number numerical sequence to form a numerical sequence 011 to be characterized; corresponding elements 0, 0 are extracted according to the corresponding relationship between the identifier fig. 3 and the elements of the management sequence number numerical sequence to form a numerical sequence 000 to be characterized.

It should be understood that, in this embodiment, in addition to the two types of maps in descending order of the map numbers of the respective labeled maps, the maps respectively correspond to the lower-order elements to the higher-order elements of the management number value sequence, or correspond to the higher-order elements to the lower-order elements of the management number value sequence, respectively, the maps may also correspond to the elements of the management number value sequence in unordered order of the map numbers of the respective labeled maps.

For example, the management sequence number value sequence is binary 110011000, there are three value sequences to be characterized, the identifier map has three

identifier maps

1, 2 and 3, and

elements

0, 1 and 1 are extracted according to the correspondence between the identifier map 1 and the elements of the management sequence number value sequence to form a value sequence 011 to be characterized; extracting elements 0, 0 and 0 according to the corresponding relationship between the identifier FIG. 2 and the elements of the management sequence number numerical sequence to form a numerical sequence 000 to be characterized; and extracting

elements

1, 1 and 0 according to the corresponding relation between the identifier of the figure 3 and the elements of the management sequence number numerical sequence to form a numerical sequence 110 to be characterized and the like.

It should be understood that, as long as the corresponding rule is preset, it is within the scope of the present invention to implement one-to-one correspondence between the identifier map and the numerical sequence to be represented by the identifier map composed of the elements of the numerical sequence.

It should be understood that the change of the value in the element of the value sequence does not affect the corresponding relationship between the identifier chart and the value sequence to be characterized in the identifier chart composed of each element, for example, assuming that the value sequences to be characterized in the above example are a, b and c, which correspond to the identifier chart 1, the identifier chart 2 and the identifier chart 3, respectively, after the value of the element of the value sequence a to be characterized is changed to 1, 1 and 0, b is 0, 0 and 1, and c is 0, 0 and 1, the value sequences to be characterized a, b and c are changed to 110, 001 and 001. At this time, the numerical value sequences a, b, and c to be characterized still correspond to the identification fig. 1, the identification fig. 2, and the identification fig. 3 one by one, but at this time, the numerical values of the elements in the numerical value sequences to be characterized respectively corresponding to the identification fig. 1, the identification fig. 2, and the identification fig. 3 are respectively changed to 1, 0, 1, 0, and 1.

In this embodiment, the marking line cosine value range of each marking map corresponds to a specific numerical sequence, and when the numerical sequence represented by each marking map composed of the elements of the management sequence number numerical sequence of the extracted article matches with the specific numerical sequence corresponding to the cosine value range of a certain marking line of each marking map, an identification point is set on the marking line.

For example, referring to fig. 5, there are three identification maps with

figure numbers

1, 2 and 3, each of which has a reference point, a reference straight line extending from the reference point by a length L0, and a marking straight line perpendicular to the reference straight line. The marking straight line of each marking graph is divided into 4 sections by a point b0, a point b1, a point b2, a point b3 and a point b4, and the connecting line of the 5 points and the reference point divides the value range of the cosine value of 0-1 into 4 parts. Setting: the value range of the cosine value corresponding to the line segment from the point b0 to the point b1 is 0.75-1, and the line segment corresponds to the numerical sequence 11; the value range of the cosine value corresponding to the line segment from the point b1 to the point b2 is 0.5-0.75, and the line segment corresponds to the numerical sequence 10; the value range of the cosine value corresponding to the line segment from the point b2 to the point b3 is 0.25-0.5, and the value range corresponds to the numerical sequence 01; the value range of the cosine value corresponding to the line segment from the point b3 to the point b4 is 0-0.25, and the value range corresponds to the numerical value sequence 00; the management number value sequence is 101101, then marking points are respectively set on marking line segment points b1 to b2 in fig. 1, marking line segment points b0 to b1 in fig. 2, and marking line segment points b2 to b3 in fig. 3.

In this embodiment, each marking line segment may not be on the same side of the reference straight line, and some marking line segments may be on the other side of the reference straight line, so long as the corresponding cosine value range is not on the side, the corresponding marking point setting may still be performed according to the above setting manner.

In this embodiment, the number sequences corresponding to the marking segment cosine value ranges of different marking diagrams may be different, for example, each marking segment cosine value range of the marking diagram 1 in fig. 5 may be set to sequentially correspond to the number sequences 00, 01, 10, and 11 to be characterized; the cosine value range of each marking line segment in fig. 2 can be set to sequentially correspond to the numerical value sequences 11, 10, 01 and 00 to be represented; the cosine value ranges of the marking line segments in fig. 3 may be set to sequentially correspond to the numerical value sequences 11, 01, 10, and 00 to be characterized.

It should be understood that, in the present embodiment, the lengths of the marking line segments of the respective marking drawings may be the same or different. The length of each marking line segment has no influence on the setting of the marking point.

In this embodiment, the reference straight line, the marking straight line, and the connection line between the end point of each marking line segment and the reference point of each marking graph may not be displayed, and only the reference point of each marking graph, the end point of each marking line segment, and the set identification point are correspondingly reserved. For example, as shown in fig. 5, there is a map in which only the reference points and points b0 through b7 are located, and the set identification points are located.

It should be understood that, in the present embodiment, the set identification point may be in the form of a circle as shown in fig. 5, or may also be in the form of a triangular point, a circular point, a square point, or the like. In fact, there is no limitation on the arrangement of the marking points, as long as the marking points can be distinguished from the reference points and the end points of the marking line segments, and the marking points are within the protection scope of the present invention. In fact, each identification map in the present embodiment may also display only the setting reference point and the identification point.

In this embodiment, a regular pattern may be further disposed on the article, and a geometric center point of the regular pattern is used as a reference point. The regular pattern may be a regular pattern such as a circle, a rectangle, a triangle, a diamond, etc., and the center point of the regular pattern may or may not display the setting, for example, referring to fig. 6, only one circle, the end points of each marking line segment, and the set marking points are displayed on one marking map. It should be understood that the end points of each marking line segment and the set marking points may or may not be all within the regular pattern (e.g., the marking pattern shown in fig. 6), or may not be all within the regular pattern.

For example, referring to fig. 9, for example, referring to fig. 5, there are three identification maps with

figure numbers

1, 2 and 3, each of which has a reference point, a reference straight line extending from the reference point by a length L0, and a marking straight line perpendicular to the reference straight line. The marking straight line of each marking graph is divided into 4 sections by a point b0, a point b1, a point b2, a point b3 and a point b4, and the connecting line of the 5 points and the reference point divides the value range of the cosine value of 0-1 into 4 parts.

It should be understood that, in this embodiment, in the process of setting the identifier map and the identifier point according to the method for setting the object control mark, an interference identifier map may also be set. That is, in the process of setting the identifier map and the identifier point according to the pattern setting policy, the correspondence between the identifier map and the element of the management sequence number value sequence, and the mapping relationship between the cosine value range of the marking line segment of each identifier map and the value sequence, the identifier map and the identifier point may be set on the article according to the preset interference identifier map setting rule (for example, one interference identifier map is set every two identifier maps). At this time, when the identification map is identified according to the article identification method, only the effective identification map is operated, and the extraction of the elements of the numerical sequence is not performed on the interference identification map.

It should be noted that the present embodiment is mainly illustrated by binary numbers, but does not represent that the present invention only uses binary numbers as the numerical value sequences. For example, when the numerical sequence is a decimal number, the cosine value range of one identification graph can be divided into 10 intervals, and one interval represents one of the numerical values 0 to 9.

In this embodiment, a table of correspondence between the management serial number and the user may also be set, see table 1. It should be understood that the management serial numbers stored in table 1 are recorded in the form of binary number value sequences, and in fact, they may be converted into octal, decimal, hexadecimal, etc. forms and stored in the management serial number value sequence and user correspondence table as the management serial numbers.

Therefore, when the safety management is carried out on the article (especially when a safety accident such as sample leakage occurs), the corresponding user or responsible person can be quickly found according to the numerical sequence of the management serial numbers.

In this embodiment, the current object to be managed and controlled for setting the identifier map may be a mobile terminal (such as a mobile phone, a tablet computer, a portable multimedia player, etc.) or a mobile terminal component (such as a motherboard, a central processing unit, a battery, etc.), etc. When the current object to be controlled is the mobile terminal, a marker map can be set in an ink area around a display screen on the front side of the mobile terminal, so that visual safety management of the mobile terminal can be realized. For example, when a photo of the mobile terminal is leaked out of the network, the article management system can find out who uses the corresponding mobile terminal according to the identification map on the photo, so that a related responsible person can be quickly determined, and the leakage source is eliminated.

When the article to be managed is a mobile terminal or a mobile terminal component, the mobile terminal may be a terminal as shown in fig. 1, and the mobile terminal component may be a camera, a microphone, a sensor, a memory, a controller, a power supply, and the like as shown in fig. 1.

Third embodiment

Referring to fig. 11, fig. 11 is a schematic structural diagram of an article control mark setting apparatus 3 according to a third embodiment of the present invention, including:

and the identifier map setting module 31 is configured to set an identifier map on the current to-be-managed article according to the pattern setting policy.

It should be understood that, in the present embodiment, the pattern setting strategy includes: the method comprises the steps of setting h marking graphs (h is more than or equal to 2) on an article, setting a reference point for each marking graph, determining a reference straight line which takes the reference point as a starting point and extends with the length of L0, and determining a marking straight line which intersects with the end point of the reference straight line and is perpendicular to the reference line, wherein the marking straight line is divided into i marking line segments (i is more than or equal to 2), and the cosine value ranges corresponding to the head point and the tail point of each marking line segment represent a numerical sequence. The cosine value is obtained by taking a reference straight line as an adjacent edge and respectively taking a connecting line of a starting point and head and tail points of the marking line segment as a bevel edge.

The distribution module 32 is configured to determine a management sequence number numerical sequence of the article, and extract, according to a preset correspondence between each identifier map and an element of the management sequence number numerical sequence, an element corresponding to each identifier map from the management sequence number numerical sequence to form a numerical sequence to be characterized by each identifier map;

In this embodiment, the elements of the management number value sequence refer to the values constituting the management number value sequence, which may constitute a plurality of small value sequences for representing each identifier map. It should be understood that the number of elements of the small numerical sequence of the numerical composition of the elements may be predetermined, for example, the numerical sequence shown in the previous example may also be that each element is a numerical sequence, and the small numerical sequence of the numerical composition shown in the previous example has 9 elements. It should also be understood that the management number value sequence includes, but is not limited to, the binary numbers shown in the previous examples, and may also be a value sequence in octal, decimal, hexadecimal, etc. It should be noted that the elements of the numerical sequence refer to the respective numerical values constituting the management sequence number numerical sequence, and the numerical sequence to be characterized by the identifier map is determined by the numerical values and the number of the elements.

the management sequence number numerical sequence is a k-bit m-system sequence, the number n of marking line segments contained in each marking graph is the same, and the value of n is greater than or equal to m to the power of (k/h). It should be understood that, at this point, the number of elements of the numerical sequence to be characterized per identifier map is k/h.

identifier maps

It should be understood that, in this embodiment, in addition to the two types of maps in descending order of the map numbers of the respective labeled maps, the maps respectively correspond to the lower-order elements to the higher-order elements of the management number value sequence, or correspond to the higher-order elements to the lower-order elements of the management number value sequence, respectively, the maps may also correspond to the elements of the management number value sequence in unordered order of the map numbers of the respective labeled maps. As long as the corresponding rule is preset, the numerical sequences to be represented of the identification diagrams consisting of the identification diagrams and the elements of the numerical sequences can be in one-to-one correspondence, which is within the protection scope of the invention.

It should be understood that a change in a value within an element of a value sequence does not affect the correspondence between the identifier map and the value sequence to be characterized by the identifier map formed by the respective element.

In this embodiment, the marking line cosine value range of each marking map corresponds to a specific numerical sequence, and when the numerical sequence represented by each marking map, which is composed of the elements extracted by the allocation module 32 from the management sequence number numerical sequence of the article, matches with the specific numerical sequence corresponding to a certain marking line cosine value range of each marking map, the marking module 33 sets a marking point on the marking line.

It should be understood that, in this embodiment, each marking line length of each marking map may be the same or different, and the size of each marking line length has no influence on the setting of the marking point. The reference straight line, the marking straight line, and the connecting line between the end point of each marking line segment and the reference point of each marking graph may not be displayed, and only the reference point of each marking graph, the end point of each marking line segment, and the set identification point are correspondingly reserved.

The center point of the regular graph may or may not display settings. The end points of each marking line segment and the set marking points may or may not be all in the regular pattern, or may not be all in the regular pattern.
