The Interface of the map may specifically be a map API (application programming Interface). The thermal image is an image of at least one of density, distribution, and trend of change of the risk coordinate points on the feedback map. The coordinate points on the thermal image correspond to corresponding thermal force values.

S212, determining the emergency standby position according to the thermal image.
The emergency standby position is a position where workers are standby. The emergency standby position can be determined according to distribution information of the thermal image in a map or according to a recommended position displayed in the map.

And in the searched risk coordinate points, the heat power value of each risk coordinate point is obtained according to the straight-line distance between each risk coordinate point and other risk coordinate points, and the probability of re-occurrence of the risk coordinate points can be intuitively expressed through the heat power values. The thermal image generated according to the danger coordinate point and the corresponding thermal value can intuitively show the probability of possible danger at different positions on the map, so that the danger standby position which quickly reaches the danger position can be accurately selected according to the thermal image, the time for the danger standby position to reach the danger position is shortened, and the efficiency is improved.
In one embodiment, obtaining the thermal value of each of the at-risk coordinate points according to the straight-line distance comprises: acquiring the corresponding linear distance of each risk coordinate point; if the straight-line distance corresponding to the danger coordinate point is within the preset distance interval, counting the number of other danger coordinate points corresponding to the straight-line distance within the preset distance interval; respectively multiplying the number in the preset distance interval by the corresponding heat power weight value of the preset distance interval to obtain an additional heat power value corresponding to each risk-appearing coordinate point in the preset distance interval; and adding the additional heat value to the basic heat value to obtain the heat value of each risk coordinate point.
The preset distance interval is an interval of a straight line distance from the danger coordinate point. The preset distance interval may be specifically 0 to 1000 meters, or 1000 to 2000 meters. The thermodynamic weight is a numerical value from which a thermodynamic value is calculated. The thermal weight may be 50 or 20. And the basic heat value of each risk coordinate point is consistent. The base heat value may specifically be 10.
Specifically, the server acquires the corresponding linear distance of each risk coordinate point, marks other risk coordinate points corresponding to the linear distance once when the corresponding linear distance of each risk coordinate point is within a preset distance interval, and counts the number of the other risk coordinate points corresponding to the linear distance within the preset distance interval according to the number of the marks. After the server counts the number of other danger coordinate points corresponding to each danger coordinate point in each preset distance interval, the number in each preset distance interval is multiplied by the corresponding thermal power weight value of the preset distance interval, and each additional thermal power value corresponding to each danger coordinate point in each preset distance interval is obtained.

Namely, the thermal force value of the dangerous coordinate point is calculated according to P10 + N50 + M20.
In this embodiment, statistics is performed according to the linear distance of each risk coordinate point and the preset distance interval, so that the calculation process can be simplified, and the calorific value can be quickly calculated according to the number of other risk coordinate points corresponding to the linear distance. And the efficiency of calculating the thermodynamic value of each risk coordinate point is improved.
In one embodiment, importing each of the risk coordinate points and the corresponding thermal value into a map, and generating a thermal image on the map, includes: importing each risk coordinate point and the corresponding heat value into a map; determining the position of each risk coordinate point in a map; marking each danger coordinate point with a corresponding thermal value; on the map, marking a heat value for other coordinate points on the map according to the linear distance between the coordinate points and the insurance coordinate points; the larger the linear distance between other coordinate points and the risk coordinate point is, the smaller the corresponding thermal value is; and generating a thermal image according to the thermal value marked on the map.
Each coordinate point in the area covered by the thermal image in the map has a corresponding thermal value, and the larger the distance between other coordinate points in the area covered by the thermal image and the risk coordinate point is, the smaller the corresponding thermal value is. The thermal image may particularly use different colors to distinguish different thermal force values.
In one embodiment, the linear distance between the other coordinate point and the emergency coordinate point on the map and the thermal value of the other coordinate point may be linearly negative, for example, the thermal value of the other coordinate point is Y, the thermal value of the emergency coordinate point is a, the linear distance between the other coordinate point and the emergency coordinate point is X, and when the negative correlation coefficient of X is-b, Y is a-bX, where 0< X < a/b. The linear distance between the other coordinate points on the map and the emergency coordinate point and the thermal value of the other coordinate points may also be in non-linear negative correlation, for example, the thermal value of the other coordinate points is Z, the thermal value of the emergency coordinate point is c2, the linear distance between the other coordinate points and the emergency coordinate point is W, and when the negative correlation coefficient of W is-d 2, Z is c2-d2W2, where 0< W < c/d.

Wherein, according to the size of the thermal image imaged on the map, the range of the area covered by the thermal image 306 is larger than the range of the area covered by the thermal image 304, and the range of the area covered by the thermal image 304 is larger than the range of the area covered by the thermal image 302. The corresponding thermal value of the coordinate point in the black area in the thermal image is larger than that of the coordinate point in the grid area, and the corresponding thermal value of the coordinate point in the grid area is larger than that of the coordinate point in the twill area.
