For example:
assuming that the number of the position information is 98 and the preset number acquired by the electronic device is 100, the electronic device determines that the number of the position information is smaller than the preset number.
The electronic equipment judges whether mutation position information and/or static position information exist or not, judges whether the mutation position information and/or the static position information exists or not based on the position information at different moments, the static position information is position information which keeps the current position information for a preset time, the preset time can be set according to the working condition, abnormality can occur if the position information of the offshore platform does not change for a long time, and the preset information can be set to be 10 minutes.
Step S1022, if the preset number is not reached, and/or mutation position information and/or static position information exist, it is determined that at least one worker is abnormal.
For the embodiment of the application, if the quantity of the position information determined by the electronic device does not reach the preset quantity, it is indicated that the position information disappears, that is, the staff possibly disappears, so that the electronic device determines that at least one staff is abnormal. And if the electronic equipment determines that the quantity of the position information reaches the preset quantity, indicating that the workers are all in the monitoring range. Taking step S1021 as an example:

If the electronic equipment determines that the sudden change position information exists, it is indicated that the staff may fall off, and if the static position information exists, it is indicated that the staff may be asphyxia, and the staff is kept still in place, so that it is determined that at least one staff is abnormal.
In one possible implementation manner of the embodiment of the present application, the method includes step S105 (not shown), step S106 (not shown), and step S107 (not shown), and step S105 may be executed after step S1021, wherein,
and step S105, if the number does not reach the preset number, reducing the positioning precision, and further acquiring the position information with a larger area.

Step S106, judging whether the quantity of the position information reaches the preset quantity.
For the embodiment of the application, the electronic device determines whether the number of the position information reaches a preset number, for example:
assuming that the number of the position information is 100 and the preset number acquired by the electronic device is 100, the electronic device determines that the number of the position information reaches the preset number.
And S107, if the preset number is not reached, circularly executing the step of reducing the positioning accuracy, further acquiring the position information with a larger area, and judging whether the number of the position information reaches the preset number until the positioning accuracy reaches the preset accuracy.
For the embodiment of the present application, assuming that the number of the location information currently acquired by the electronic device is 50, taking step S1021 as an example:
the electronic equipment determines that the quantity 50 of the position information does not reach the preset quantity 100, and then the electronic equipment reduces the positioning precision to 2-2.5 m; the number of the position information of the new positioning accuracy obtained by the electronic equipment is 88, and if the number 88 of the position information determined by the electronic equipment does not reach the preset number of 100, the positioning accuracy of the electronic equipment is reduced to 2.5-4 m; the number of the position information of the electronic equipment, which obtains the new positioning accuracy, is 98, the number 98 of the position information determined by the electronic equipment does not reach the preset number 100, the positioning accuracy of the electronic equipment is reduced to 4-5 meters, the number of the position information of the electronic equipment, which obtains the new positioning accuracy, is 100, and the number of the position information determined by the electronic equipment reaches the preset number 100.
If the positioning accuracy reaches the preset accuracy which is 5.5 meters, the electronic equipment stops reducing the positioning accuracy, the area of the excessive offshore platform is exceeded due to reduction, and the possibility of new position information is low. For example:
the number of the position information of the new positioning accuracy obtained by the electronic equipment is 98, the number 98 of the position information determined by the electronic equipment does not reach the preset number 100, the positioning accuracy of the electronic equipment is reduced to 5.5 meters, the number of the position information determined by the electronic equipment does not reach the preset number, and the number of the position information determined by the electronic equipment is 2, which indicates that 2 workers may be abnormal.
The number of position information is judged step by reducing the positioning accuracy so that the number of position information is more accurate.
In one possible implementation manner of the embodiment of the present application, the step S1021 of determining whether there is mutation position information includes a step S1021a (not shown), a step S1021b (not shown), a step S1021c (not shown), and a step S1021d (not shown), wherein,
step S1021a, obtaining a preset number of historical time instants and historical position information corresponding to the historical time instants.
For the embodiment of the application, the electronic equipment acquires the historical moments with preset number, the electronic equipment can acquire the historical moments based on the internal clock chip, and can also acquire the historical moments through the Internet and the cloud server, wherein the preset number is at least 3, so that the electronic equipment can generate curves subsequently. The electronic device obtains historical location information corresponding to historical time, for example: assuming that the preset number is 4;
the electronic equipment acquires the historical position information of 9:00:00 as (100, 200, 50);
the electronic equipment acquires historical position information of 9:00:01 as (102, 200, 45);
the electronic equipment acquires the historical position information of 9:00:02 as (105, 200, 20);
the electronic device obtains the historical location information of 9:00:03 as (110, 200, 5).
In step S1021b, a motion curve is fitted based on the historical time and the historical position information.

If the position information acquired by the electronic equipment is longitude and latitude, the electronic equipment directly establishes a rectangular coordinate system according to the longitude and latitude horizontal and longitudinal coordinates. For example:
the electronic device fits the motion curve based on (100, 50), (102, 45), (105, 20), (110, 5), and the electronic device can fit by the least square method, and the obtained motion curve is: y =0.2x2-47x +2758, where x has a minimum value of 100 and y has a minimum value of 0.
In step S1021c, it is determined whether the slope of the motion curve has a sudden change.
For the embodiment of the application, the electronic device determines that all slopes of the cloud top curve have sudden changes, and the electronic device can calculate a plurality of slopes at optional points in the motion curve, so as to determine whether the slopes have sudden changes. For example:
the electronic equipment acquires four monitoring points (101, 51.2), (103, 38.8), (108, 14.8) and (112, 2.8) based on the motion curve, and a first slope obtained based on the first two monitoring points is-6.2; and the second slope obtained based on the last two detection points is-3, the electronic equipment determines that the slope does not have a sudden change within the range of +/-0.1 of the first slope, and determines that the slope has a sudden change within the range of +/-0.1, so that the electronic equipment determines that the range is [ -6.3, -6.1], and the second slope is-3 and does not exist in the range, so that the electronic equipment determines that the slope has a sudden change.
At step S1021d, if it is, it is determined that mutation position information exists.
For the embodiment of the application, if the electronic device determines that the slope has a sudden change, which indicates that a worker may fall, the electronic device determines that the information of the position with the sudden change exists.
