It is understood that the communication range of the fixed communication device needs to cover the corresponding first working area.
Illustratively, the first working area is a range with a length of 8 meters and a width of 3 meters, and then the communication range of the corresponding fixed communication equipment needs to cover the range with a length of 8 meters and a width of 3 meters at least, so that the fixed communication equipment can accurately interact with the equipment in the first working area, and the subsequent judgment process is ensured to be accurate.

After the central point and the area boundary reference points are determined, the central point and each area boundary reference point are connected to obtain a plurality of first reference connection lines, and for a rectangle, the number of the first reference connection lines is 4. Meanwhile, the scheme can also obtain the first connection length of the first reference connection line.
In some embodiments, S132 (the connecting the center point with the region boundary reference point to obtain a first reference connecting line, and determining a first connection length of the first reference connecting line) includes:
if the first working area is a regular rectangular area, calculating a first connection length of the first reference connection line by the following formula,
wherein the content of the first and second substances,

as a value of the width active area,
is a preset error compensation value.
In the above formula, by
The length of the diagonal of the rectangular area can be calculated,
representing the length of the diagonal line, namely the distance from the central point to the boundary reference point of each area, namely the first connection length of the first reference connection line; meanwhile, the scheme is also provided with a preset error compensation value
And the worker can adjust the first connection length according to the actual situation.

It can be understood that the first connection length calculated in step S132 is a length on a plane, and when the fixed communication device has a height, the range covered by the fixed communication device is larger than the first connection length, so that the present embodiment obtains the corresponding second connection length according to the first connection length and the preset fixed height.
In some embodiments, the step S133 (obtaining a preset fixed height for fixing the fixed communication device, and obtaining a corresponding second connection length according to the first connection length and the preset fixed height) includes:
the second connection length is calculated by the following formula,
wherein the content of the first and second substances,
for the purpose of the second connection length,
is a preset fixed height.
It can be understood that the above formula utilizes the pythagorean theorem to calculate the preset fixed height and the first connection length, and obtain the second connection length. At this time, the second connection length is the shortest range that the fixed communication device needs to cover, and when the coverage range of the fixed communication device is smaller than the second connection length, the communication range cannot completely cover the first working area.
S134, comparing the second connection length with a preset communication correspondence table, and determining the fixed communication equipment corresponding to the communication distance which is greater than the second connection length and closest to the second connection length in the communication correspondence table, wherein each type of fixed communication equipment has the communication distance corresponding to the fixed communication equipment.
It should be noted that, the present solution is provided with a communication correspondence table, and the communication correspondence table has a preset relationship between the communication distance and the fixed communication device, for example, when the communication distance is within 8 meters, the corresponding fixed communication device may be a bluetooth module, and when the communication distance is within 20 meters, the corresponding fixed communication device may be a zigbee module.
After the second connection length is obtained, the fixed communication equipment corresponding to the communication distance which is greater than the second connection length and closest to the second connection length needs to be found from the communication correspondence table.

In order to judge whether the corresponding staff is in the first working area through the fixed communication equipment, the scheme can be used for equipping mobile communication equipment for each staff, and the mobile communication equipment is arranged corresponding to the first working area. It can be understood that when the mobile communication device is located in the corresponding first working area, the fixed communication device actively establishes a communication connection with the mobile communication device.
In practical application, mobile communication equipment can set up on staff's helmet, and when the staff removed, the mobile communication equipment who corresponds can remove thereupon, and simultaneously, the setting mobile communication equipment can not influence staff's operation on staff's helmet yet.
In some embodiments, S2 (where a corresponding mobile communication device is set for each first working area, each mobile communication device is carried by a worker during working, and the fixed communication device actively establishes a communication connection with the mobile communication device when the mobile communication device is located in the corresponding first working area) includes S21-S22:
s21, the fixed communication device actively searches for the mobile communication devices in the coverage area.
It will be appreciated that in order to establish a connection with a mobile communication device, the fixed communication device of the present solution actively searches for mobile communication devices within its coverage area.

and S31, sending the generated current connection data to the server by the fixed communication equipment at preset time intervals.
For example, the fixed communication device may send the current connection data generated by the fixed communication device to the server at intervals of 3 minutes without sending the current connection data in real time, so that the data processing amount of the server can be reduced.
And S32, the server extracts the current connection label in the current connection data and acquires the shift schedule corresponding to the fixed communication equipment at the current moment.

S33, determining the scheduling time period corresponding to the current moment in the scheduling list, extracting the preset connection labels in the scheduling time period, wherein different scheduling time periods in the scheduling list correspond to different preset connection labels.
For example, there may be 2 shift schedules in the shift schedule, from 8 am to 8 pm and 8 pm to 8 am; for example, from 8 am to 8 pm, it is staff A, B and C working in the first working area G1, and then during the time period from 8 am to 8 pm, the preset connection tag in the corresponding shift schedule is the connection tag corresponding to staff A, B and C; for another example, from 8 pm to 8 am, staff D, E and F work in first work area G1, and then during the time period from 8 pm to 8 am, the preset connection tag in the corresponding shift schedule is the connection tag for staff D, E and F.
And S4, if the current connection label is judged to correspond to the preset connection label, the first working area is not changed.
After determining the preset connection label in the corresponding scheduling time period, the server compares the current connection label with the preset connection label, if the current connection label corresponds to the preset connection label, it indicates that the corresponding worker normally works in the corresponding first working area, and if the worker normally attends the duty, the first working area is not changed.
And S5, if the current connection label is judged not to correspond to the preset connection label, taking the first working area as a second working area, and acquiring working video data in the second working area.
It can be understood that, if the current connection tag does not correspond to the preset connection tag, for example, the current connection tag is one less than the preset connection tag, which indicates that a worker leaves the first working area, at this time, the scheme may use the first working area as the second working area, and acquire the working video data in the second working area.
It should be noted that, in order to prevent the situation that the judgment is inaccurate when the fixed communication device or the mobile communication device is in a connection failure, the scheme performs secondary verification on the second working area by using the working video data to judge the true situation of the second working area.
And S6, performing image extraction on the working video data to obtain a plurality of interested area images, and outputting first reminding information to a management terminal if the number of the interested area images is different from the number of the preset connecting labels.

It can be understood that, according to the scheme, the secondary verification can be performed on the condition of the working area by matching with the fixed communication equipment and the mobile communication equipment through the embodiment, so that the condition of misjudgment is prevented from occurring.
In some embodiments, S6 (extracting the working video data to obtain a plurality of interested region images, and outputting the first reminding information to the management terminal if the number of the interested region images is different from the number of the preset connection tags) includes S61-S65:
and S61, acquiring working video images at multiple moments in the working video data, and acquiring a first pixel value of each first pixel point in the working video images.
For example, according to the scheme, an image in the working video data can be extracted every 10S, and the image is used as a working video image, and meanwhile, the scheme obtains the first pixel value of each first pixel point in the working video image.
It should be noted that, according to the scheme, a plurality of working video images are obtained, and the plurality of working video images are used for judgment, so that the accuracy of the judgment result can be improved.
And S62, acquiring a preset video image, wherein the preset video image is an image extracted in advance when the second working area does not have a worker, and acquiring a second pixel value of each second pixel point in the preset video image.
In the scheme, in order to compare the working video images, images extracted in advance when the second working area does not have the staff, namely the preset video images, can be obtained, and meanwhile, the second pixel value of each second pixel point in the preset video images can be obtained.
And S63, respectively performing coordinate processing on the working video image and the preset video image by taking the central pixel point as the origin of coordinates to obtain a first coordinate of each first pixel point in the working video image and a second coordinate of each second pixel point in the preset video image.

After the coordination processing, the scheme can also obtain the first coordinate of each first pixel point in the working video image and the second coordinate of each second pixel point in the preset video image.
It should be noted that, the device for acquiring the preset video image and the working video image in the present scheme may be arranged above the first working area, and only in this way, the image in the first working area may be completely acquired.
And S64, sequentially traversing the first pixel points in each working video image, comparing the first pixel value of each first pixel point with the second pixel value of the corresponding second pixel point according to the corresponding relation between the first coordinate and the second coordinate, and determining all the pixel points of the working video image which do not correspond to the second pixel value of the second pixel point as third pixel points.

It can be understood that there is no staff in the preset video image, there is staff in the work video image, and the difference between the preset video image and the work video image lies in the presence or absence of the staff, so that the obtained non-corresponding pixel points can be regions corresponding to the staff.
And S65, taking the first coordinate corresponding to the third pixel point as a third coordinate, connecting all adjacent third pixel points according to the third coordinates of all the third pixel points to form an interested area image, and outputting first reminding information to the management terminal if the number of the interested area images is different from the number of preset connection labels.
It can be understood that the third pixel points corresponding to one worker are adjacent, and the third pixel points are connected according to all adjacent third pixel points to form the interested area image, and it can be further understood that if there are 3 workers, there are 3 corresponding interested area images. If the number of the images of the region of interest is different from the number of the preset connection labels, and the fact that the staff really leave the first working area is indicated, first reminding information is output to the management terminal.

In the scheme, the judgment of the interested area image by the scheme is possibly influenced by some small articles, such as tea cups and other articles, and the small articles are rejected by the scheme.
Because the size of the articles such as the tea cup is small, the number value of the corresponding third pixel point is small, and therefore when the number value of the third pixel point is judged to be smaller than the preset number value, the image of the region of interest corresponding to the third pixel point is deleted, and the influence on subsequent judgment is avoided.
And S652, after all the interested area images smaller than the preset number value are judged to be deleted, the final interested area image is obtained.
Illustratively, the number of the initially obtained region-of-interest images is 6, 3 region-of-interest images smaller than a preset number value are deleted, and then the remaining 3 region-of-interest images are the final region-of-interest images.
