BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 It is a flowchart of a monitoring and reminder method based on a signboard mainly embodied in this embodiment.

[0039] Figure 2This is a structural block diagram of a monitoring and reminder system based on a signboard mainly embodied in this embodiment. DETAILED DESCRIPTION

[0040] The present invention is further described in detail below in conjunction with the following examples.

[0041] Reference Figure 1 , a monitoring reminder method based on a signboard, the method comprising the following steps:

[0042] S1. Select a target monitoring area, count the sight concentration area of ​​the crowd in the target monitoring area to obtain a first sight concentration area, and count the first concentration angle value based on the first sight concentration area.

[0043] S2. When it is determined that there is a monitor in the straight line angle position direction of the first sight concentration area, the corresponding first execution monitor is selected, and a variable signboard warning is performed according to the first execution monitor, and the first signboard warning result is output.

[0044] S3. According to the warning result of the first signboard and the first concentrated sight area, draw the first test data curve graph and the first original data curve graph, perform difference comparison between the first test data curve graph and the first original data curve graph to obtain a first change degree value, and according to the first change degree value, obtain the first signboard warning plan.

[0045] S4. When it is determined that there is no monitor in the straight line angle position direction of the first visual focus area, select the corresponding second execution monitor one and the second execution monitor two, perform a changeable sign warning according to the second execution monitor one and the second execution monitor two, and output the second sign warning result.

[0046] S5. According to the second sign warning result and the first sight concentration area, draw a second test data curve graph and a second original data curve graph, perform difference comparison between the second test data curve graph and the second original data curve graph to obtain a second change degree value, and obtain a second sign warning solution according to the second change degree value.

[0047] Specifically, by detecting the concentrated sight range of the crowd in the selected target monitoring area, and according to the statistically determined straight line angle position direction of the first concentrated sight area, whether there is a monitor, two distinctive analysis steps are performed, that is, two situational analyses are performed to set up two signboard warning schemes accordingly, so as to reduce the extremely low efficiency and low practicability caused by processing the characteristic information in various situations with a unified scheme. Through situation-based processing, the efficiency of the subsequent corresponding signboard warning work is improved, and the diversification of the scheme setting can further expand the attention and novelty of the signboard warning. By counting the first concentrated angle value in the first visual concentration area, the front monitor at the corresponding appropriate angle position is selected. If the position is far away, people cannot see the sign information clearly. If the position is close and the height is high, people cannot see the sign information within the normal visual range. Or, the monitors on both sides of the corresponding appropriate angle position are selected for path connection to perform subsequent sign movement path warning processing. By setting different sign warning schemes for different situations, the breadth of the sign warning content being known can be greatly improved, and the time consumed for being known can be shortened, which greatly improves the efficiency of the sign monitoring reminder work.

[0048] The specific step S1 includes the following sub-steps:

[0049] The monitor location information and monitoring area are obtained, and according to the monitor location information, the monitoring area is divided into multiple areas to obtain an area set, and a target monitoring area is selected from the area set.

[0050] The crowd density in the target monitoring area is detected, and a density threshold is preset. When the crowd density is greater than the density threshold, the crowd sight concentration area in the target monitoring area is counted to obtain a first sight concentration area.

[0051] The first concentrated angle value is obtained by counting the sight concentration angle values ​​of people in the first sight concentration area.

[0052] Specifically, such as the monitor location information (if it includes: position 1, position 2, position 3, position 4, position 5), area set (if they are: A, B, C, D, E respectively), target monitoring area (if it is A), crowd density (if it is 60%), preset density threshold (if it is 50%), the first line of sight concentration area (if it is a1, a1 is included in A), and the first concentration angle value (if it is 30°).

[0053] The specific step S2 includes the following sub-steps:

[0054] When it is determined that there is a monitor in the straight line angle position direction of the first sight concentration area, the corresponding first execution monitor is selected from the monitor position information according to the first concentration angle value.

[0055] According to the first execution monitor, a changeable signboard warning is performed on the people in the target monitoring area, and a first signboard warning result is output.

[0056] Specifically, when it is determined that there is a monitor in the straight angle position direction of the first visual concentration area (then the monitor at this straight angle position can be selected, because people can just observe the sign warning information within the normal viewing angle range. If there are multiple monitors that meet the angle of 30° but the distances are different: J0, J1, J2, then a monitor at an appropriate distance is selected to perform subsequent sign warning work, such as selecting based on the normal vision distance), the first execution monitor (if it is J1), the first sign warning result (the variable sign warning here means that the content color or font on the sign can be changed to attract people's attention).

[0057] The specific step S3 includes the following sub-steps:

[0058] According to the warning result of the first signboard, a first detection interval is preset, and according to the first detection interval, a first concentration degree and a first concentration duration of the sight lines of the crowd in the target monitoring area in the first sight concentration area are detected.

[0059] A first data curve graph to be tested is drawn according to the first concentration level and the duration of the first concentration.

[0060] The first original concentration degree and the first original concentration maintenance time in the first sight concentration area are counted and plotted into a first original data curve graph.

[0061] A first variation degree value is obtained by performing a difference comparison between the first test data curve graph and the first original data curve graph.

[0062] According to the first variation degree value, a first repeated warning interval duration is preset, and according to the first repeated warning interval duration, a repetitive sign warning process is performed on the first sign warning result according to the first repeated warning interval duration, and a first sign warning scheme is output.

[0063] Specifically, such as presetting a first detection interval (i.e., conducting an intermittent real-time effect detection, if the interval for the next sign attention degree detection is 10 seconds later), a first concentration degree (i.e., the crowd's line of sight concentration degree: the ratio of the number of people whose line of sight is concentrated in the first line of sight concentration area to the total number of people, which is the first concentration degree, if it is C1, the first concentration maintenance duration: that is, the maintenance duration of C1, if it is T1), a first data graph to be tested (i.e., drawing a change curve with T as the x-axis and C as the y-axis), a first original data graph (the explanation is the same as the first data graph to be tested, and no further explanation is given here. It should be noted that the first original data graph refers to a change curve graph drawn from the recorded data of the historical period), a first change degree value (i.e., the first data graph to be tested The difference calculation is performed on the part with a large concentration difference in the same time period in the first original data curve chart, and the obtained difference is the first change degree value. If it increases by 20%), the first repeated warning interval is preset (the larger the change degree value, the shorter the repeated warning interval, because it means that the current sign attention level is high, and continuous sign change warnings can be carried out in a short time, which can further improve the attention level. The change degree value and the repeated warning interval are proportionally evaluated. If the preset ratio is 5:1, the first change degree value is 20%, and the corresponding preset first repeated warning interval is 4 seconds for a repeated sign change warning), and the first sign warning plan (that is, every 4 seconds, the J1 monitor issues a repeated sign change warning).

[0064] The specific step S4 includes the following sub-steps:

[0065] When it is determined that there is no monitor in the straight line angle position direction of the first sight concentration area, the corresponding second execution monitor one and second execution monitor two are selected from the monitor position information according to the first concentration angle value.

[0066] The position points of the second execution monitor 1 and the second execution monitor 2 are connected by a path to obtain a mobile warning path.

[0067] According to the mobile warning path, a movable signboard warning is performed on the people in the target monitoring area, and a second signboard warning result is output.

[0068] Specifically, for example, when it is determined that there is no monitor in the straight-line angle position direction of the first visual concentration area (two of the monitors located on both sides can be selected, because there is no monitor at a suitable distance in the straight-line angle position direction, then two monitors at a suitable distance on both sides are selected for subsequent signboard warning processing), the second execution monitor one and the second execution monitor two (if they are: J3 and J4, and the angles are both in line with 30°), the mobile warning path (that is, the straight-line distance between J3 and J4 is connected, and the connected path is the moving path for the subsequent signboard warning, starting from the straight-line angle position direction of the first visual concentration area as the starting point for the signboard warning, and starting to move in the direction of J3 or J4 to attract the attention of the crowd and expand the crowd's familiarity), the second signboard warning result (the changeable signboard warning here means that the content color or font on the signboard can be changed to attract people's attention).

[0069] The specific step S5 includes the following sub-steps:

[0070] According to the warning result of the second signboard and the first detection interval, the regional position movement status of the area where the crowd's line of sight is concentrated in the target monitoring area and the duration of the second concentration are detected.

[0071] The second concentration degree is obtained by counting the sight concentration degree of the crowd belonging to each regional moving position in the regional position moving status.

[0072] A second test data curve graph is drawn according to the second concentration level and the duration of the second concentration.

[0073] The second original concentration degree and the second original concentration maintenance time in the first sight concentration area are counted and plotted into a second original data curve graph.

[0074] The second measured data curve graph and the second original data curve graph are compared for difference to obtain a second variation degree value.

[0075] According to the second variation degree value, a second repeated warning interval duration is preset, and according to the second repeated warning interval duration, a repetitive sign warning process is performed on the second sign warning result according to the second repeated warning interval duration, and a second sign warning scheme is output.

[0076] Specifically, such as the movement status of the regional position and the duration of maintaining the second concentration (if the above-mentioned mobile warning path is divided into multiple path blocks, including: L1, L2, L3, L4, L5, among which if the path block where the sign warning starts is in a straight line angle position direction with the first sight concentration area, if it is L2, then the moving position of L2 is counted, if it is L3 and L4 respectively), the second concentration level (that is, the sight concentration level of the crowd in the L2, L3, and L4 position areas respectively: the ratio of the amount of people whose sight is concentrated in the first sight concentration area to the total amount of people, that is, the second concentration level, if it is C2), the duration of maintaining the second concentration (the same as the explanation of the duration of maintaining the first concentration, such as the attention time of the crowd's sight concentration area moving simultaneously with the direction from L2 to L3 and then to L4, that is, the maintenance time of C2, if it is T2), the second data to be tested curve graph, the second original data curve graph (same as the first original data The explanation of the curve graph is the same and will not be explained in detail here), the second change degree value (that is, the difference between the parts of the second test data curve graph and the second original data curve graph with a large concentration difference in the same period is calculated, and the difference is the second change degree value. If it increases by 30%), the preset first repeated warning interval (the larger the change degree value, the shorter the repeated warning interval, because it means that the current sign has a high level of attention. Continuous sign change warnings can be made in a short time, which can further increase the attention level. The change degree value and the repeated warning interval are proportionally evaluated. If the preset ratio is 5:1, the second change degree value is 30%, and the corresponding preset second repeated warning interval is 6 seconds for a repeated sign change warning), the second sign warning plan (that is, every 6 seconds, the J3 and J4 monitors make a repeated sign change warning.

[0077] A monitoring and reminder system based on a signboard, by applying a monitoring and reminder method based on a signboard as described above, includes a sight concentration area statistics unit, a first condition warning unit, a scheme one setting unit, a second condition warning unit and a scheme two setting unit, referring to Figure 2, a target monitoring area is selected through a sight concentration area statistical unit, and the sight concentration area of ​​the crowd in the target monitoring area is counted to obtain a first sight concentration area, and a first concentration angle value is counted according to the first sight concentration area; when the first condition warning unit determines that there is a monitor in the straight line angle position direction of the first sight concentration area, a corresponding first execution monitor is selected, and a variable signboard warning is performed according to the first execution monitor, and a first signboard warning result is output; a first test data curve graph and a first original data curve graph are drawn according to the first signboard warning result and the first sight concentration area through a scheme one setting unit, and a first change program is obtained by performing a difference comparison between the first test data curve graph and the first original data curve graph degree value, and obtain the first signboard warning scheme according to the first change degree value; when the second condition warning unit determines that there is no monitor in the straight line angle position direction of the first line of sight concentration area, select the corresponding second execution monitor one and the second execution monitor two, and perform a variable signboard warning according to the second execution monitor one and the second execution monitor two, and output the second signboard warning result; through the scheme two setting unit, according to the second signboard warning result and the first line of sight concentration area, draw the second test data curve graph and the second original data curve graph, perform difference comparison between the second test data curve graph and the second original data curve graph to obtain the second change degree value, and obtain the second signboard warning scheme according to the second change degree value.
