Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness. It should be noted that, in the technical solution of the embodiment of the present invention, the acquisition, storage, application, and the like of the personal information of the related user all conform to the regulations of the relevant laws and regulations, and do not violate the custom of the public order.
At present, the society begins the aging process, and a part of the old population is bound to enter professional nursing community life.
As the elderly grow older, bodily functions decline and the risk of accidents also increase, communities need to provide 7 × 24 hours of full-scale care services, many of which are location-related, for the elderly.
At present, there are many devices and methods for detecting and reporting position information in the market, such as various bracelets and watches with GPS. However, these products often require active initiation of a location acquisition request.
In conclusion, the data sources existing in the prior art are relatively single, the adaptation range is narrow, and comprehensive and accurate positioning service cannot be provided, so that the accuracy of safety early warning is poor.
In order to solve the technical problem of poor accuracy of safety early warning, the following technical scheme in the embodiment of the invention can be adopted.
Referring to fig. 1, fig. 1 is a main flow diagram of a safety early warning method according to an embodiment of the present invention, where location information passively identified by a user equipment is combined with location information actively identified by the user equipment to locate a current trajectory of a user, so as to implement safety early warning for the user. As shown in fig. 1, the method specifically comprises the following steps:
s101, after receiving a message of identifying the user equipment by the radio frequency identification beacon, receiving a message of actively searching the Bluetooth low-power-consumption beacon by the user equipment, wherein the user equipment is carried by a user, and the radio frequency identification beacon and the Bluetooth low-power-consumption beacon are both arranged in a place.
The technical scheme provided by the embodiment of the invention is applied to the aged-care community. In the senior community, a variety of sites are included. Such as: the positions of places such as community entrances and exits, old-age houses, activity centers, machine rooms, kitchens and the like. In order to timely know the position of the user, the position of the user is identified through the user equipment by using the beacon, and then the track of the user is constructed according to the position of the user in a period of time.
Beacons are typically located in a venue. As an example, the beacon is installed in a place such as a community entrance, an old house entrance, an activity center entrance, a machine room, and a kitchen.
In an embodiment of the present invention, the beacon includes a Radio Frequency Identification (RFID) beacon and a Bluetooth Low Energy (BLE) beacon.
The radio frequency identification technology is one of automatic identification technologies, non-contact bidirectional data communication is carried out in a radio frequency mode, and a recording medium is read and written in the radio frequency mode, so that the aims of identifying a target and exchanging data are fulfilled.
The Bluetooth low energy consumption is also called low-power consumption Bluetooth, is a personal area network technology designed and sold by a Bluetooth technical alliance, and aims to be used for emerging applications in the fields of medical care, sports and fitness, beacons, security protection, home entertainment and the like.
In the embodiment of the invention, the user carries the user equipment with the user. That is, the user device is a device that the user carries with him. The user equipment includes an identifier capable of being identified by the radio frequency identification beacon and an identifier that identifies the bluetooth low energy beacon.
In embodiments of the present invention, it is contemplated that the radio frequency identification beacon can actively identify the user equipment without the user equipment actively searching. Radio frequency identification beacons may be placed in critical locations. As an example, the key locations include one or more of community entrances, exits, rooms, and kitchen locations.
The key place is a building for limiting the access times of users in the aged-care community. As an example, key sites are: and (4) a community entrance. The user is in the inside activity of endowment community more, and under the normal condition, the number of times of coming in and going out of community gate is less than and predetermines the number of times to prevent the emergence of the condition such as user's wandering away. As another example, key sites are: the kitchen often has a number of risk factors for the elderly: fire, water and electricity. In order to guarantee the safety of users in the old-age community, the users are forbidden to enter a kitchen.
In the embodiment of the invention, the location of the place can also be determined by adopting a Bluetooth low energy beacon. And determining the location of the place by using the Bluetooth low-power beacon, specifically, actively searching the Bluetooth low-power beacon by the user equipment.
It should be noted that one trigger condition for the ue to actively search for the bluetooth low energy beacon is: the radio frequency identification beacon successfully identifies the user equipment. If the radio frequency identification beacon successfully identifies the user equipment, the user passes through a key place. In view of user security, it is desirable to track a user, i.e., trigger a user device to search for a bluetooth low energy beacon to obtain the user's location of a venue.
If the radio frequency identification beacon does not successfully identify the user equipment, it indicates that the user does not pass through a key place, and the user safety does not need to be considered, and the user does not need to be tracked. And then avoid the invalid search of the user equipment, and then improve the standby time of the user equipment.
In an embodiment of the invention, the search for bluetooth low energy beacons is performed by the user equipment. It will be appreciated that after the radio frequency identification beacon identifies the user device, the user device may actively search for a bluetooth low energy beacon. As an example, after the radio frequency identification beacon identifies the user device, a message identifying the user device is sent to the user device, and the user device starts to actively search for the bluetooth low energy beacon after receiving the message identifying the user device.
The embodiment of the invention relates to a beacon and user equipment. It should be noted that the beacon and the user equipment may exchange information. Both the beacon and the user equipment may send information. As an example, after the rfid beacon identifies the user device, a message is sent that the rfid beacon identifies the user device. The user equipment triggers a search to search for the Bluetooth low energy beacon when receiving a message that the radio frequency identification beacon identifies the user equipment. And after searching the Bluetooth low-power beacon, the user equipment sends a message that the user equipment actively searches the Bluetooth low-power beacon.
For the user equipment, as the user moves, the user equipment gradually approaches the rfid tag installed in the place. The user equipment enters the identification range of the radio frequency identification beacon, and the radio frequency identification beacon sends a message for identifying the user equipment.
That is, the message that the radio frequency identification beacon identifies the user equipment is a message that the user equipment enters the identification range of the radio frequency identification beacon and is transmitted. As an example, a user device enters the identification range of a radio frequency identification beacon, which transmits a message. As another example, the user equipment enters the identification range of the rfid beacon, and after receiving the information sent by the rfid beacon, the user equipment may send a message to the server to further determine the specific location through the bluetooth low energy beacon.
In the process of actively searching the Bluetooth low-power beacon by the user equipment, the Bluetooth module can be adopted to judge that the position information of the user equipment is in a preset safety range. Wherein one or more bluetooth low energy signals may be actively searched. As an example, the user moves from place a to place B and then from place B to place C while moving. The site A is provided with a Bluetooth low-power beacon a, the site B is provided with a Bluetooth low-power beacon B, and the site C is provided with a Bluetooth low-power beacon C. The user equipment actively searches for 3 Bluetooth low energy consumption signals, namely a Bluetooth low energy consumption signal of the Bluetooth low energy consumption beacon a, a Bluetooth low energy consumption signal of the Bluetooth low energy consumption beacon b and a Bluetooth low energy consumption signal of the Bluetooth low energy consumption beacon c.
Then, the message that the user equipment actively searches for the bluetooth low energy beacon is a message that the user equipment actively searches for one or more bluetooth low energy signals and determines the location information of the user equipment.
S102, identifying the place position in the message of the user equipment according to the radio frequency identification beacon, actively searching the place position in the message of the Bluetooth low-power beacon by the user equipment, and positioning the current track of the user by combining the existing track of the user equipment.
And after actively identifying the user equipment, the radio frequency identification beacon sends a message for identifying the user equipment by the radio frequency identification beacon. The message identifying the user device by the radio frequency identification beacon includes the location of the venue of the device identification beacon. The user equipment actively searches the Bluetooth low-power beacon and sends a message that the user equipment actively searches the Bluetooth low-power beacon. The message that the user equipment actively searches for the bluetooth low energy beacon includes the venue location of the bluetooth low energy beacon. And then, positioning the current track of the user is realized.
Referring to fig. 2, fig. 2 is a schematic flowchart of locating a current trajectory of a user according to an embodiment of the present invention. The method specifically comprises the following steps:
s201, determining the existing place position of the user according to the safety track information of the user equipment.
The safety track information of the user equipment is a set of the place and the position of the user in a preset time period before the current time point. The place position of the user in the preset time period before the current time point is called as the existing place position.
Furthermore, the existing location of the user can be determined according to the safe track information of the user equipment.
S202, recognizing the place position in the message of the user equipment based on the radio frequency identification beacon, and actively searching the place position and the existing place position in the message of the Bluetooth low-power beacon by the user equipment to locate the current track of the user.
For the user, the trajectory of the user device may change due to the user being in motion. In order to locate the current trajectory of the user, positioning needs to be achieved based on the current position of the user and the existing location position.
Specifically, the radio frequency identification beacon is used for identifying a place position in a message of the user equipment, the user equipment actively searches the place position in the message of the Bluetooth low-power beacon, and the current track of the user is established according to the sending time of the message and by combining the existing place position. It will be appreciated that the current trajectory of the user includes a venue location and a point in time at which the venue location corresponds to a message.
In the embodiment of fig. 2, the radio frequency identification beacon actively identifies the location of the user equipment, and the user equipment actively searches the location of the bluetooth low energy beacon to locate the current track of the user, so as to determine the current movement condition of the user in the endowment community, thereby laying a foundation for safety early warning.
S103, sending early warning information based on the current track of the user and the historical track of the user.
For the user, the current trajectory of the user and the historical trajectory of the user may be located according to the technical solutions of S101 to S102. As one example, the user's historical track includes the user's track for the previous 10 days. Day 1, day 2, day 3, day 4, day 5, day 6, day 7, day 8, day 9, and day 10 trajectories.
It will be appreciated that the historical trajectory of the user is the trajectory of the user over a historical period of time. Consider that users in an aging community typically have fixed activity times and activity tracks. As an example, user 1 arrives at 10 o 'clock to 11 o' clock in the morning from an apartment via a restaurant to a garden, and returns from the garden to the apartment via a gym.
And determining to send early warning information according to the current track of the user by taking the historical track of the user as a comparison basis. Early warning information can be sent to the user equipment, so that the user is reminded. As an example, the pre-warning information may also be sent to a control center of the senior community.
In one embodiment of the invention, the current track of the user is determined to deviate from the historical track of the user by combining the current time point, and then the early warning information is sent. As an example, the current time point is used as the end point of the current track, and the historical tracks of the user are compared from the start point of the current track. And if the current track of the user deviates from the historical track of the user, sending early warning information. As an example, if the maximum deviation distance between the current track of the user and the historical track of the user is greater than a preset deviation threshold, it is determined that the current track of the user deviates from the historical track of the user, and the warning information is sent.
In the embodiment of the invention, after receiving the message of identifying the user equipment by the radio frequency identification beacon, receiving the message of actively searching the Bluetooth low-power beacon by the user equipment, wherein the user equipment is carried by a user, and the radio frequency identification beacon and the Bluetooth low-power beacon are both arranged in a place; identifying the place position in the message of the user equipment according to the radio frequency identification beacon and actively searching the place position in the message of the Bluetooth low-power beacon by the user equipment, and positioning the current track of the user by combining the existing track of the user equipment; and sending early warning information based on the current track of the user and the historical track of the user. The radio frequency identification beacon and the Bluetooth low-power beacon are adopted to determine the position of the place, so that the positioning accuracy of the user can be improved. And then, safety early warning is carried out by combining the historical track of the user so as to improve the accuracy of the safety early warning.
The following describes the technical solution in the embodiment of the present invention by way of example.
Radio frequency identification beacons are arranged in key places of the aged-care community, such as community gates, machine rooms and kitchens. When a user carries a user equipment close to the radio frequency identification beacon, the user equipment is activated by a message sent by the radio frequency identification beacon and can send an event to a background. Such as: a message is sent identifying the user device by the radio frequency identification beacon. The user device starts to actively search for bluetooth low energy beacons. And after the user equipment searches the Bluetooth low-power-consumption beacon, sending a message that the user equipment actively searches the Bluetooth low-power-consumption beacon.
And identifying the place position in the message of the user equipment according to the radio frequency identification beacon, actively searching the place position in the message of the Bluetooth low-power beacon by the user equipment, and positioning the current track of the user by combining the existing track of the user equipment. And sending early warning information to the user equipment and the background under the condition that the current track of the user has large deviation. As one example, the location of the user may be included in the warning information.
In an embodiment of the invention, the user equipment is carried by the user, and the existing user equipment cannot adjust an interaction mode aiming at physiological characteristics of the elderly in consideration of the fact that most users in the elderly community are older, so that the equipment is inconvenient to use.
In particular, the screen of the user device is an important medium for user interaction, and the appropriate feedback is an important part of the user experience. If the operation is too complex and the operation is inconvenient for the old, the interactive logic also needs to be simplified.
In one embodiment of the invention, the user device is a device that outputs information according to a priority determined by one of the following parameters, user physical characteristics, information importance and user preset ratings.
It will be appreciated that where the user device displays a variety of information, the display may be in accordance with a priority. The physical characteristics of the user include: a hearing disorder and/or a vision disorder. Such as: the physical characteristics of the user relate to auditory disorder, and when the voice message playing skip display state and the text message display skip display state exist simultaneously, the text message skip state is given higher priority. The following steps are repeated: the physical characteristics of the user relate to visual disturbance, and when the voice message playing skip display state and the text message display skip display state exist simultaneously, the voice message skip state is given higher priority.
The importance of the information is determined according to the urgency of the information. As an example, the information importance is: in case of emergency, the information is regarded as the highest priority information.
The user preset level is a level determined according to a user's setting. As an example, the user sets the priority of the first type of information to high; setting the priority equipment of the second type of information as middle; the priority of the third type of information is set to low.
In one embodiment of the invention, the user device has a single key whose mode of operation includes a short press and a long press. The operation that the duration of pressing a single key exceeds a pressing threshold value is called long-time pressing operation; an operation in which a single key is pressed for a period of time not exceeding the pressing threshold is referred to as a short-press operation.
As an example, the user equipment starts up a default display page set to A, possible display pages set to B, C, D, etc., and the subordinate pages of each page are B1, B2, C1, D1, etc., respectively.
Referring to fig. 3, fig. 3 is a schematic diagram of page switching of a user equipment according to an embodiment of the present invention. Event triggering, when the user equipment in fig. 3 has a subsequent selectable display page, the user may enter a subsequent page of the page B by performing 1 operation in short, and sequentially switch between subsequent pages by performing 1 operation in continuous short. Such as: B1-B2-B3, and when the page reaches the last page B3, the page is switched back to the first page B1, namely B3-B1 after 1 short press. The user can exit the display page by long-press operation, and return to the default display page a.
Referring to fig. 4, fig. 4 is a schematic diagram of another user equipment page switching according to an embodiment of the present invention. Due to event triggering, when the user equipment in fig. 4 has a plurality of subsequent selectable display pages, several display pages are automatically arranged in sequence according to default settings.
The user can enter the 1 st subsequent display page through short pressing for 1 time, enter the 2 nd subsequent display page through short pressing for 2 times, and so on. If the default sequence of the pages is B, C and D, entering the B display page by 1 time, entering the C display page by 2 times, and entering the D display page by 3 times. The situation after entering the subsequent display page is consistent with the single display page operation. The last menu can be returned by a long press operation. If B returns to A.
In embodiments of the present invention, beacons are employed to learn venue locations. Therefore, a large number of beacons need to be deployed in advance. Maintenance is also required for beacons. I.e. the running state of the beacon needs to be detected regularly or irregularly.
Referring to fig. 5, fig. 5 is a schematic flow chart of screening out abnormal beacons according to an embodiment of the invention. The method specifically comprises the following steps:
s501, dividing the beacon into beacon groups according to the historical track of the user and the place position of the beacon.
During the process of user movement, the user equipment is connected with the beacon in sequence to exchange information. Then the abnormal beacon can be screened out by using the connection number of the beacon and the user equipment.
Specifically, the beacons are divided into beacon groups according to the historical tracks of the users and the location positions of the beacons.
As one example, the historical track of user 1 relates to venue location A, venue location B, and venue location C. The historical track of user 2 relates to venue location a and venue location B. The historical track of user 3 relates to venue location a, venue location E and venue location F. Beacons involved in a historical track having more than two identical venue locations may be divided into the same beacon group. It should be noted that the beacon includes a radio frequency identification beacon and/or a bluetooth low energy beacon.
S502, in each group of beacon groups, abnormal beacons are screened out according to the connection times of the beacons and the user equipment.
In each group of beacon groups, if the difference between the connection times of the beacon and the user equipment and the connection times of the beacon and the user equipment in the same group is continuously greater than a connection threshold value in two time periods, the beacon is taken as an abnormal beacon.
Referring to fig. 6, fig. 6 is a schematic diagram of a beacon state according to an embodiment of the present invention. The beacon in fig. 6 includes three states, which are: a normal working state; a suspicious operating state; an abnormal operating state. The abnormal operation state beacon is an abnormal beacon.
In a first preset time period T1, if the difference between the connection times of the beacon and the user equipment and the connection times of the beacon and the user equipment in the same group is greater than a connection threshold 1, the beacon enters a suspicious working state from a normal working state.
And in a second preset time period T2, if the difference between the connection times of the beacon and the user equipment and the connection times of the beacon and the user equipment in the same group is greater than a connection threshold value 2, the beacon enters an abnormal working state from a suspicious working state. And then, whether the beacon is abnormal or not is determined through manual inspection. Wherein T1 is greater than T2 and the connection threshold 1 is greater than or equal to the connection threshold 2.
And in a second preset time period T2, if the difference value between the connection times of the beacon and the user equipment and the connection times of the beacon and the user equipment in the same group is less than or equal to a connection threshold value 2, the beacon enters a normal working state from a suspicious working state.
In the embodiment of FIG. 5, the user device may scan surrounding beacons to complete the location fix while the user is active in the senior community. And then according to the number of times of connection between the user equipment and the beacon, judging whether the beacon is in a state or not so as to screen out the abnormal beacon.
In the embodiment of the invention, the safety early warning of the user is realized by using the beacon in the aged-care community. When the user moves in the endowment community, the current track of the user can be positioned through the beacon. When the user is close to the key area, other equipment can be linked to determine whether to open the access control of the key area. Early warning information can also be sent to the user equipment.
Referring to fig. 7, fig. 7 is a schematic view of a main structure of a safety precaution device according to an embodiment of the present invention, where the safety precaution device can implement a safety precaution method, as shown in fig. 7, the safety precaution device specifically includes:
