Detailed Description
The invention is further described with reference to the following drawings and detailed description.
Fig. 1 is a schematic flowchart illustrating steps of a data recommendation method based on a wearable device according to an embodiment of the present invention.
In fig. 1, the method comprises steps S1-S3, and is performed by a central server scheduling wireless communication data transmitted by a wearable device, a smart-chip meal card.
In a specific embodiment, the method is applied to a campus environment, and particularly to a dining room environment for a campus dining time period.
Of course, the invention can also be applied to other scenes with intensive people or people gathering in time periods, such as factories, industrial parks, office parks, and the like;
specifically, the hardware basis for executing the method is as follows:
m target users are provided with intelligent chip meal cards, and N target users in the M target users wear the wearable equipment.
Taking the application of the method to the campus environment, especially to the dining room environment in the campus dining time period as an example, the target users can be students at school, teachers and other people who have meals in the school dining room.
It can be understood that, in most cases, students, teachers and other people having meals in a school dining room are provided with the smart chip meal cards, that is, M target users are provided with the smart chip meal cards;
on the basis, some persons can configure a smart watch, a smart bracelet, smart glasses or other wearable devices.
The wearable device is configured with a data positioning program, and the current position of the wearable device is sent to the central server through the data positioning program.
As one example, the data positioning procedure may be a GPS based positioning APP or LBS based positioning procedure.
As another example, a wearable device does not necessarily rely solely on GPS to provide location services. Some wearable devices use a-GPS, location beacons, identified network access points, etc. to determine location and provide location-based services, such as navigation. Thus, the wearable device may also provide location services in areas and locations where traditional GPS-based location may not be available.
Of course, unlike a smart-chip meal card, a wearable device is not mandatory to configure the device, and thus, it can be understood that N target users among M target users wear the wearable device, i.e., M ≧ N >1.
In one embodiment, the central server is configured with a near field card reading terminal, and the smart chip meal card is activated when the smart chip meal card approaches the near field card reading terminal.
It can be understood that the near-field card reading terminal is arranged at a target location, such as a school dining room, and when a target person has a meal, the card needs to be swiped for consumption, that is, when the smart chip meal card approaches the near-field card reading terminal, the smart chip meal card is activated, and each activation is sensed and counted by the central server.
Typically, upon reaching a meal time period (e.g., lunch 11-00.
When the number of target people is large and the guide is lacked, due to the fact that dining positions and dish preparation positions of a dining room are limited, if the number of people reaching the target position (a dining room) in the same time period is large, a congestion phenomenon can occur, and user experience is affected.
In the prior art, the peak section of dining is informed in advance through experience values, and the target personnel are advocated to have dinner by peak, for example, warm prompt: 12:00-12:30 divided into meal peak period. However, such a static uniform reminding method is not effective. For example, reminder 12:00-12: after the peak period of dining 30, the number of people having dinner in the next day may be rather small, and other periods may be crowded, and the environmental change cannot be sensed in real time.
Therefore, the invention provides an improved technical scheme, which makes full use of the existing wearable equipment and the existing campus specific equipment to realize personalized data recommendation after data collection and analysis in specific time periods and specific places, and can dynamically sense environmental changes in real time and send out reminding information.
Specifically, referring to fig. 1, the steps S1 to S3 are specifically performed as follows:
s1: when detecting that the cumulative activation times InvM of the smart chip meal card exceeds a first preset time PresetM within a first preset time period PresetT, acquiring the current positions of N target users wearing the wearable device and the activation states of the smart chip meal card configured by the M target users within the first preset time period PresetT;
as a specific example, the first preset time period PreSetT may be a regular meal time period, such as 7:00-9: 00. 11:00-13: 00. 17:00-19:00;
of course, the above is only an illustrative example, and different schools and industrial parks may open meals in other periods, so that the first preset time period PreSetT is determined by those skilled in the art according to actual scenarios, and the embodiment does not specifically limit the first preset time period PreSetT.
The first preset number of times PreSetM may also be determined based on the maximum number of people queued while the current dining scene can provide, the maximum number of people having a meal, and the like, for example, if the current dining room has 500 dining positions, the first preset number of times PreSetM may be set to 500 × 75% =375;
as a further preference, the first preset number of times PreSetM is set differently based on different first preset time periods PreSetT, i.e. the first preset number of times PreSetM is set dynamically.
For example, when the first preset time period PreSetT is set to the first time period PreSetT1, the first preset number of times PreSetM is set to PreSetM1;
for example, the first time period PreSetT1 is 7:00-9:00, the first preset number of times PreSetM is set to PreSetM1=500 × 85% =425;
when the first preset time period PreSetT is set to the second time period PreSetT2, the first preset number of times PreSetM is set to PreSetM2;
for example, the second period PreSetT2 is 11:00-13:00, the first preset number of times, preSetM, is set to PreSetM2=500 × 75% =375;
when the first preset time period PreSetT is set to the third time period PreSetT3, the first preset number of times PreSetM is set to PreSetM3;
for example, the third time period PreSetT3 is 17:00-19:00, the first preset number of times, preSetM, is set to PreSetM3=500 × 60% = 300;
when the accumulated activation times InvM of the intelligent chip meal card exceeds the first preset times Preset within the first preset time period Preset, the number of the target users arriving at the restaurant is close to a preset upper limit, and other target users not arriving at the restaurant need to be guided in time;
it is understood that the present embodiment supports sending a guidance notification to a target user who is wearing the wearable device.
Acquiring current positions of N target users wearing the wearable device and activation states of the intelligent chip meal cards configured by the M target users within the first preset time period Preset;
s2: determining K users to be reminded in the N target users, wherein the intelligent chip meal card configured by the K users to be reminded is not activated within the first preset time period PreSetT, and the distance difference value between the current position of the K users to be reminded and other positions of other users activated within the first preset time period PreSetT of the intelligent chip meal card is greater than a first preset distance value PreSetDInv;
it can be seen that, in step S2, the determined K users to be reminded are not ready to eat a meal by swiping a card (the smart chip meal card has not been activated within the first preset time period PreSetT) and have not reached the restaurant range (the difference between the current location of the user to be reminded and the distance between the current location of the smart chip meal card and other locations of other users that have been activated within the first preset time period PreSetT is greater than the first preset distance value PreSetDInv);
s3: sending data recommendation information to the K users to be reminded, wherein the data recommendation information is used for indicating the K users to be reminded to go to a target position in a second prediction time period after the first preset time period PresetT, and the distance difference between the target position and other positions of other users, which are activated by the intelligent chip meal card in the first preset time period PresetT, is smaller than a second preset distance value PresetDou;
wherein M, N, K are all positive integers, and M > N > K >1.
In step S3, K users to be reminded have been identified, and at this time, a recommendation message needs to be sent to the K users to be reminded to indicate the target users that the current time period is recommended not to go to the restaurant, but the current time period is recommended to go to the target location only within a second prediction time period, for example, after 5 minutes and 10 minutes (the specific time period is according to the prediction result), the restaurant is going to.
Preferably, the central server obtains the length of a first preset time period PreSetT, the accumulated activation times InvM, and the current positions of N target users wearing the wearable device, and predicts a plurality of first predicted numbers of target users reaching the target position in a plurality of time periods in the future; and when the first prediction quantity is smaller than a preset upper limit value, determining the second prediction time period.
As an example, the central server may count the cumulative number of activations invam in the current period, the current locations of the N target users wearing the wearable device, predict the number of people going to the target location, the number of people already located within the target location range, the number of people about to leave the target location range in different periods based on the length of the first preset time period PreSetT (which may be predicted based on the average meal time for determining the number of meals) and thereby determine a plurality of first predicted numbers of target users arriving (located) at the target location range within 5 minutes, 10 minutes, and 30 minutes in the future;
assuming that a first predicted number of target users reaching the destination location within 5 minutes in the future is Y5; a first predicted number of target users reaching the destination location within 10 minutes in the future is Y10; assuming that a first predicted number of target users reaching the destination location within 30 minutes in the future is Y30;
setting a preset upper limit value as PresetM 75%;
if Y10, Y30 and Y10 are all smaller than a preset upper limit value, taking the future 5 minutes as the second prediction time period;
that is to say, when a plurality of first prediction amounts are all smaller than a preset upper limit value, taking the earliest prediction time period in a plurality of prediction time periods corresponding to the plurality of first prediction amounts as the second prediction time period, and reminding the K users to be reminded of going to a destination position in the second prediction time period;
of course, if only one first prediction number is smaller than the preset upper limit value, only one determined second prediction time period exists.
Therefore, in the embodiment of fig. 1, a specific part of target crowds needing to send the data recommendation message is determined in a specific time period, so that staff drainage in a specific place is realized, staff congestion is avoided, and user experience is improved.
The method described in fig. 1 may also be implemented based on automated programming of computer program instructions. Fig. 2 is a flowchart illustrating a logic flow of a program when the wearable device-based data recommendation method in fig. 1 is implemented automatically by a computer program.
Meanwhile, as mentioned above, different schools and industrial parks may open meals in other time periods, and therefore, the first preset time period PreSetT is determined by a person skilled in the art according to an actual scenario, which is not particularly limited in this embodiment.
For this reason, in the program flow given in fig. 2, the specific first preset time period PreSetT is not defined any more, but the recommended cycle duration cordit is set;
for example, setting the recommendation cycle duration cordit =30 minutes, if the cumulative activation time InvM of the smart chip mess card caused by card swiping in a restaurant is detected to exceed the first preset time PreSetM within 30 minutes from the current time node, the data recommendation method described in fig. 1 is started.
Specifically, the computer flow depicted in FIG. 2 is summarized in the form of a pseudo-code language as follows (step designations are omitted in FIG. 2):
SS1, initializing cumulative activation times InvM =0; setting a recommended period duration cordidt;
SS2; judging whether the intelligent chip mess card is detected to be close to the near field card reading terminal or not, if so, invM + + and Timer + +;
otherwise, returning to the step SS1;
and (4) SS3: judging whether Timer = cordidt is true, if yes, entering a step SS4;
otherwise, timer + +, return to step SS2;
and (4) SS: judging whether InvM > PresetM is true, if so, entering a step SS5;
if not, returning to the step SS1;
and SS5: acquiring current positions of N target users wearing the wearable equipment and activation states of the intelligent chip meal cards configured by the N target users in a set recommended cycle time length cordiT;
and SS6: determining K users to be reminded in the N target users;
and (7) SS: and sending data recommendation information to the K users to be reminded.
It can be understood that, in step SS6, the smart card configured by the K users to be reminded is not activated within the set recommended period duration cordit, and the distance difference between the current position of the K users to be reminded and the other positions of the other users that the smart card is activated within the set recommended period duration cordit is greater than a first preset distance value PreSetDInv;
it can be understood that, in step SS7, the data recommendation information is used to indicate that the K users to be reminded move to the destination positions in the second predicted time period after the current time node, and a distance difference between the destination positions and other positions of other users that the smart chip rice card has been activated within the set recommendation cycle duration cordit is smaller than a second preset distance value PreSetDou.
A specific optimization algorithm implemented as a computer program, wherein the PreSetM setting is related to the size of M, N, wherein:
alternatively, the first and second electrodes may be,
wherein the content of the first and second substances,
indicates the length of the first preset time period PreSetT in minutes;
represents rounding down;
represents rounding up; maxP represents the maximum number of meals or maximum meal location that the target location can provide.
Of course, as described in the foregoing embodiment of fig. 1, the first preset times PreSetM may also be set differently based on different first preset time periods PreSetT, that is, the first preset times PreSetM is dynamically set, and the first preset times PreSetM is determined by multiplying MaxP by a preset ratio value, where the preset ratio value dynamically changes with the difference of the first preset time periods PreSetT.
Fig. 3 is a schematic composition diagram of a wearable device-based data recommendation system according to an embodiment of the present invention.

the wearable device is configured with a data positioning program, and the wearable device sends the current position to the central server through the data positioning program;
the central server is provided with a near field card reading terminal, and when the intelligent chip meal card approaches the near field card reading terminal, the central server monitors that the intelligent chip meal card is activated.
The central server counts the number of activated cumulative activation times InvM of the intelligent chip meal card in a first preset time period Preset;
when the accumulated activation times InvM exceeds a first preset time PresetM, the central server acquires the current positions of N target users wearing the wearable device and the activation states of the smart chip dining cards configured by the M target users within the first preset time period PresetT;
the central server determines K users to be reminded in the N target users and sends data recommendation information to the K users to be reminded, wherein the data recommendation information is used for indicating the K users to be reminded to move to a target position in a second prediction time period after the first preset time period Preset;
the intelligent chip meal card configured by the K users to be reminded is not activated within the first preset time period Preset, and the distance difference value between the current position of the K users to be reminded and other positions of other users activated within the first preset time period Preset of the intelligent chip meal card is greater than a first preset distance value PresetDInv;
wherein M, N, K are all positive integers, and M > N > K >1.
It is understood that the hardware architecture described in fig. 3 may implement the method embodiment described in fig. 1, and may also implement the method flow described in fig. 2, and the description is not repeated here.
Similarly, the central server obtains the length of a first preset time period PreSetT, the accumulated activation times InvM, and the current positions of N target users wearing the wearable device, and predicts a plurality of first predicted numbers of target users reaching the target position in a plurality of time periods in the future; and when the first prediction quantity is smaller than a preset upper limit value, determining the second prediction time period.
Preferably, the central server obtains the length of a first preset time period PreSetT, the accumulated activation times InvM, and the current positions of N target users wearing the wearable device, and predicts a plurality of first predicted numbers of target users reaching the target position in a plurality of time periods in the future; and when the first prediction quantity is smaller than a preset upper limit value, determining the second prediction time period.
As an example, the central server may count the cumulative number of activations invam in the current period, the current locations of the N target users wearing the wearable device, predict the number of people going to the target location, the number of people already within the target location range, the number of people about to leave the target location range in different periods based on the length of the first preset time period PreSetT (which may be predicted by determining the average meal time for the number of meals based on historical data), thereby determining a plurality of first predicted numbers of target users reaching the target location within 5 minutes, 10 minutes, and 30 minutes in the future;
when a plurality of first prediction quantities are smaller than a preset upper limit value, taking the earliest prediction time period in a plurality of prediction time periods corresponding to the plurality of first prediction quantities as the second prediction time period, and reminding the K users to be reminded of going to a target position in the second prediction time period;
of course, if only one first prediction number is smaller than the preset upper limit value, only one determined second prediction time period exists.
The wearable device is worn by N target users in the M target users, and the M target users are configured with smart chip meal cards.
With continued reference to fig. 4, fig. 4 is a schematic diagram of interaction control when the wearable device is paired with the smart chip card in the system of fig. 3.
First wearable devices worn by N target users in the M target users are paired with the first smart chip meal card;
when the first smart chip meal card is activated within the first preset time period Preset, the first wearable device is dormant within the first preset time period Preset.
It is understood that when the first wearable device is paired with the first smart chip meal card and the first smart chip meal card is activated within the first preset time period PreSetT, the current location of the first smart chip meal card may represent the current location of the first wearable device.
At this time, the first wearable device is not required to send the current position of the first wearable device to the central server through a data positioning program.
This is because, when the first smart-chip meal card was activated within the first preset time period PreSetT, it means that the first smart-chip meal card has been located near the target location for the current time period, the location of which has been sensed by the central server.
At this time, the first wearable device is dormant within the first preset time period PreSetT, so that the endurance performance of the first wearable device can be obviously improved, and the user experience is further improved.
