Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In the description of the embodiments of the present application, the terms first and second are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining a first or second may explicitly or implicitly include one or more such feature. In the description of the embodiments of the present application, plural means two or more unless specifically defined otherwise.
In order to solve the problem that the life safety of the user with the risk of sudden cardiac arrest cannot be fully guaranteed by the destination query result provided by the destination query method adopted by the related art, an embodiment of the application provides a destination query method based on AED coverage, and an execution subject of the method can be a background server. Fig. 1 is a basic flow chart of an AED coverage based destination query method provided in this embodiment, which includes the steps of:
And step 101, when a destination query request sent by a client is received, acquiring a destination set in a preset first range corresponding to the user position information according to the destination query keyword.
Specifically, the destination query request in this embodiment carries a destination query keyword and user location information, where the destination query keyword may include an accurate keyword indicating a destination location type, for example, a movie theater, a hotel, a restaurant, a recreation ground, etc., and may also include a fuzzy keyword associated with the destination location type, for example, eating meal, food, etc., and the user location information may be longitude and latitude information of a current location of a user terminal carrying a client; the destination set includes a plurality of destination entries including a destination identification and destination location information. In this embodiment, when the user has a destination query requirement, a destination query request is sent to a background server through a client carried on the user terminal, the background server uses current user location information as a center, obtains all destinations conforming to destination query keywords in a preset range, and obtains a destination set, for example, the destination location type carried by the destination query request is a movie theater, and can search out all movie theaters in a range with the user location information as a center and N kilometers as a search radius (for example, 1 kilometer), and then generate the destination set based on destination identifiers and destination location information of all movie theaters searched.
It is worth mentioning that the background server provides a Web service API with destination query, the form of the destination query request may be expressed as http:// www.aedmap.com/search query=movie theater & location=39.915, 116.404& radius=2000, where query represents a search keyword corresponding to the above destination query keyword, for example, query=movie theater, location represents user location information as a center point of a circular area search, and a specific form may be location= (latitude, longitude), radius represents a radius of the circular area search, and a default value may be 1000. It should be noted that, in practical application, the present embodiment may call the hundred-degree map API service to obtain a set of destinations within a preset first range corresponding to the user location information.
In an optional implementation manner of this embodiment, before the step of obtaining, according to the destination query keyword, the destination set in the preset first range corresponding to the user location information, the method further includes: judging whether a destination query condition based on AED coverage is met or not based on the destination query request; when a destination query condition based on AED coverage is met, the step of acquiring a set of destinations within a preset first range corresponding to user location information from the destination query keyword is performed.
Specifically, in practical applications, the destination query requirements of the user are classified into a general destination query requirement, that is, only the destination meeting the destination query keyword needs to be queried, and a destination query requirement based on the AED coverage needs to be queried, that is, the destination meeting the AED coverage requirement needs to be queried. It should be noted that not all users have potential AED usage requirements, and in order to reduce processing performance costs and increase query efficiency, this embodiment will make a decision in advance based on the destination query request, and trigger the AED coverage based destination query method only when the user has AED coverage based destination query requirements.
Further, the destination query request of the embodiment also carries the medical history information of the user; accordingly, the step of determining whether the destination query condition based on AED coverage is met based on the destination query request includes: acquiring a first safety guarantee requirement index based on a destination query keyword carried by a destination query request, and acquiring a second safety guarantee requirement index based on user medical history information carried by the destination query request; calculating a total safety guarantee requirement index by combining the first safety guarantee requirement index and the second safety guarantee requirement index; and judging whether the destination query condition based on the AED coverage is met or not based on the total safety guarantee requirement index and a preset index threshold.
Specifically, in practical application, some living places may have a great influence on the emotion of a person, such as chess and card rooms, a close-room escape experience hall, a recreation ground and the like, for people with a certain risk of cardiac arrest, arrhythmia is more easily caused, and the risk of cardiac arrest is increased, so that the type of living place to which a user needs to go has an influence on the security requirements of an AED; in addition, the disease history of different users is different, and for people with hypertension, hyperglycemia, hyperlipidemia, heart disease treatment history and family heart disease genetic history, the risk of sudden cardiac arrest is obviously higher than that of healthy people, so that the disease history of the users can also influence the AED safety guarantee requirement.
Based on this, the present embodiment comprehensively considers the destination query keyword and the user medical history information to determine whether the current destination query request meets the destination query condition based on AED coverage, specifically, the present embodiment obtains the corresponding security requirement index based on the destination query keyword and the user medical history information, and then sums or weighted averages the two security requirement indexes, and finally compares the calculated total security requirement index with a preset index threshold, and determines whether the destination query condition based on AED coverage is met according to the comparison result, where if the total security requirement index is greater than or equal to the preset index threshold, the destination query condition based on AED coverage is determined to be met.
Specifically, in this embodiment, the background server creates an AED list, records relevant information of each AED, including AED identification (e.g., a device serial number), AED location information (e.g., latitude and longitude information of a current location of the device), and the like, and in practical application, a plurality of destination location information meeting the destination query keyword may be searched within a preset range of the current location of the user.
In an alternative implementation of this embodiment, the step of acquiring the target AED location information within the preset second range corresponding to the destination location information includes: respectively acquiring AED position information of all idle AEDs in a preset second range corresponding to the position information of each destination and AED self-checking results; acquiring AED self-test results from all idle AEDs as self-test passing available AEDs; comparing the first relative distance information between the AED location information and the destination location information for all available AEDs; corresponding target AED location information for the available AED for which the first relative distance information is the smallest is obtained.
Specifically, after searching all the idle AEDs within the preset range of the destination location information, the present embodiment then compares the relative distances between all the idle AEDs and the destination, screens the AED from all the idle AEDs for available AEDs that pass the self-test, further compares the relative distances between all the available AEDs and the destination, determines the available AED with the smallest relative distance as the target AED, and acquires the location information of the target AED corresponding to the determined available AED.
In particular, the present embodiment may determine the priority of different destinations in the set of destinations in combination with their relative distances from the target AED and the user, respectively, and then rank all of the destinations according to priority, it being understood that different priorities are used to characterize the recommended level of the different destinations, which is positively correlated with the priority.
In an optional implementation manner of this embodiment, the calculation formula of the first relative distance information may be expressed as follows:
(1-cos(d/R))/2= sin 2 ((φ 2 -φ 1 ) /2)+cos(φ 1 ) cos(φ 2 )sin 2 (Δλ/2)；
wherein ,dthe first relative distance information is represented as such,Rrepresenting the radius of the earth, delta lambda represents the difference in longitude indicated by the destination location information and the corresponding target AED location information,φ 1 、φ 2 indicating the latitude indicated by the destination location information and the corresponding target AED location information, respectively.
It should be noted that, in practical applications, the calculation manner of the second relative distance information may also be implemented by referring to the calculation manner of the first relative distance information, which is not described herein again.
It should be noted that, the location information used in the above calculation formula of the relative distance information may be implemented based on different positioning technologies, such as GPS positioning, beidou satellite positioning, and the like, where positioning accuracy in the civil field is classified into standard high accuracy and RTK high accuracy. The standard high-precision magnitude is generally in the meter level, wherein the positioning precision of the single-frequency GPS module and the Beidou module is about 2 to 3 meters, and the positioning precision of the double-frequency GPS module and the Beidou module is about 1 to 2 meters; and the positioning precision of the GPS module and the Beidou module with high precision of the RTK can reach the decimeter level and the centimeter level. In practice, although the relative distance between the AED and the destination or between different AEDs may be relatively close, the relative distance between the two positioning bodies can typically be in the order of tens of meters, hundreds of meters, and based on the positioning accuracy of the aforementioned positioning technique, positioning information between the different positioning bodies can be effectively distinguished.
In an alternative implementation of this embodiment, the step of prioritizing all destination entries in the destination set in combination with the first relative distance information between all destination location information and corresponding target AED location information and the second relative distance information between the destination location information and the user location information includes: calculating a first priority score for first relative distance information between each destination location information and the corresponding target AED location information, respectively, and a second priority score for second relative distance information between each destination location information and the user location information, respectively; calculating a total priority score based on each first priority score and the corresponding second priority score, respectively; all destination entries in the destination set are prioritized according to all total priority scores.
Specifically, in the present embodiment, the first priority score is inversely related to the first relative distance information, and the second priority score is inversely related to the second relative distance information. In practical applications, the closer the relative distance between the destination and the AED affects the AED safety protection effect, i.e., the closer the AED is to the destination, the shorter the dispensing time period required in the rescue process, and accordingly, the AED can be provided for the patient at the destination as soon as possible, so that the better the AED safety protection effect is, and therefore, the first priority score can be calculated based on the relative distance, the time period of providing the AED required for rescue in the vicinity of the destination can be reflected by the first priority score, the higher the score, the shorter the time period of providing the AED required for rescue is, and for cardiac arrest patients, the higher the rescue success rate is meant, and therefore, the higher the first priority score is the destination location information has the better AED safety protection effect; in addition, the relative distance between the destination and the user affects the user travel convenience, and the closer the relative distance is, the higher the user travel convenience is, so that the second priority score can be calculated based on the relative distance, and the higher the second priority score is, the higher the destination position information has the higher user travel convenience. Next, the present embodiment may comprehensively score each destination in combination with the first priority score and the second priority score, and then prioritize each destination based on the comprehensive score, that is, sort the plurality of destination entries based on the priority score, with the destination entry with higher priority being ranked earlier.
In practical applications, if the priority ranking is performed only based on the relative distance between the destination and the AED or the relative distance between the user and the destination, the priority ranking is a one-factor priority ranking rule, if the user travel convenience of the destination is considered only, the AED security may not be considered, and if the AED security of the destination is considered only, the user travel convenience may not be considered. By adopting the multi-factor priority ordering rule provided by the embodiment, the finally ordered destination can give consideration to the travel convenience of the user and the AED safety guarantee, and the travel experience of the user can be effectively improved. It should be understood that the present embodiment may be implemented in a summation calculation manner or a weighted average calculation manner when calculating the total priority Score, and that the present embodiment may preferably be implemented in a weighted average calculation manner, that is, the total priority score= (a×score) 1 +b×Score 2 ）/（a+b），Score 1 Representing a first priority Score, score 2 The representation represents a second priority score. It should be noted that the values of the weights a and b can be flexibly set according to the actual application scene requirements, for example, for a user travel scene with travel convenience preference, the weight b can be given a larger value, while the weight a is given a relatively smaller value, and for a user travel scene with sufficient AED security requirements, the weight a can be given a larger value, while the weight b is given a relatively smaller value. Further, in practical application, considering that the importance of the AED safety guarantee effect is generally higher than the convenience of the user in traveling, it is preferable that the value of the weight a is greater than the weight b.
In an optional implementation manner of this embodiment, before the step of calculating the total priority score based on each first priority score and the corresponding second priority score, the method further includes: respectively acquiring volunteer density information in a preset third range corresponding to the position information of each destination; calculating a corresponding third priority score based on each volunteer density information; wherein the third priority score is positively correlated with the volunteer density information. Correspondingly, the step of calculating the total priority score based on each first priority score and each second priority score respectively includes: the total priority score is calculated based on each first priority score and the corresponding second and third priority scores, respectively.
Specifically, in practical application, the correct use of the AED requires a certain operation skill, and the background server of the embodiment can accept the registration request of the end user with the AED operation skill, register it as a volunteer, and if the volunteer exists near the destination, the rescue guarantee can be improved. Based on this, the volunteer of the present embodiment carries with it the volunteer terminal installed with the volunteer client, and the volunteer terminal uploads the volunteer position information to the background server at regular time, and the background server can acquire the number of volunteers whose volunteer position information is in the vicinity of the destination, and accordingly can count up the density of the volunteers, and then calculate the corresponding third priority score of the destination position information based on the density of the volunteers, in the present embodiment, the higher the density of the volunteers, the stronger the rescue assurance, and the higher the corresponding third priority score. In the process of calculating the total priority score according to the embodiment, the third priority score corresponding to the density of the volunteers can be further considered on the basis of the first priority score and the second priority score, so that the high-priority destination can be guaranteed to provide sufficient security.
It should be noted that, in the present embodiment, when calculating the total priority Score in combination with the third priority Score, reference may be made to the foregoing embodiment, that is, the calculation may be performed in a summation calculation manner or a weighted average calculation manner, and the present embodiment preferably may be performed in a weighted average calculation manner, that is, the total priority score= (a×score) 1 +b×Score 2 +c×Score 3 ）/（a+b+c），Score 1 Representing a first priority Score, score 2 Representing a second priority Score 3 Representation watchAnd a third priority score is shown, and a, b and c respectively represent the corresponding weights of the different priority scores.
In an optional implementation manner of this embodiment, before the step of calculating the total priority score based on each first priority score and the corresponding second priority score, the method further includes: acquiring sharable destination numbers of target AED position information corresponding to the destination position information respectively; wherein the sharable destination number is the number of all destinations of the target AED for which the target AED location information corresponds exist within the second range; calculating a corresponding fourth priority score according to the number of the sharable destinations; wherein the fourth priority score is inversely related to the number of sharable destinations. Correspondingly, the step of calculating the total priority score based on each first priority score and each second priority score respectively includes: the total priority score is calculated based on each first priority score and the corresponding second priority score and fourth priority score, respectively.
In particular, in practice, there may be multiple destinations in a set of destinations that are closely spaced, resulting in a single target AED being located within a second range of multiple destinations at the same time, and the target AED sharing multiple destinations, the security of which for a single destination may be impaired because the AED needs to provide security for multiple destinations at the same time. Fig. 2 is a schematic diagram of a multi-destination shared AED according to the present embodiment, in which point A, B, C represents three destinations in the destination set, respectively, and the circle centered at each destination is a region defined by a second range, and point I represents the target AED, which can be used when there is a cardiac arrest event in any one of the destinations, as can be seen to be within the second range of the three destinations. Based on this, the present embodiment calculates the fourth priority score corresponding to the target AED location information for the number of sharable destinations of the target AED corresponding to each target AED location information, and then in the process of calculating the total priority score in the present embodiment, the fourth priority score corresponding to the number of sharable destinations of the target AED may be further taken into consideration on the basis of the first priority score and the second priority score, thereby ensuring that the high priority destination can provide sufficient security.
It should be noted that, in the present embodiment, when calculating the total priority Score in combination with the fourth priority Score, reference may still be made to the foregoing embodiment, that is, the calculation may be performed by a summation calculation method or a weighted average calculation method, and the present embodiment may preferably be performed by a weighted average calculation method, that is, the total priority score= (a×score) 1 +b×Score 2 +d×Score 4 ）/（a+b +d），Score 1 Representing a first priority Score, score 2 Representing a second priority Score 4 The representation represents the fourth priority score, and a, b and d represent the weights corresponding to the different priority scores respectively.
