The technical solutions in 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 obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
It is to be noted that the terms "comprises" and "comprising" and any variations thereof in the examples and figures of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The embodiment of the application discloses a floor positioning method and device, electronic equipment and a storage medium, which can save a large amount of manpower and time cost and simultaneously obtain accurate floor information. The following are detailed below.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a floor positioning method according to an embodiment of the present disclosure. The floor positioning method described in fig. 1 is suitable for electronic devices such as smart phones and electronic devices, and the embodiments of the present application are not limited thereto. The electronic device may include, but is not limited to, a smart watch or a smart bracelet supported by a wrist, a smart ring supported by a finger, smart shoes or smart socks supported by a foot, smart glasses supported by a head, a smart helmet or a smart headband, and various non-mainstream products such as smart clothes, a bag, a crutch and accessories.
As shown in fig. 1, the floor location method may include the steps of:
101. the method comprises the steps of obtaining air pressure data collected by an air pressure meter of the electronic equipment, and judging whether a floor where the electronic equipment is located changes or not according to air pressure variation of the air pressure data.
The electronic device can acquire air pressure data in real time through the built-in barometer and can preprocess the acquired air pressure data. For example, median filtering may be performed on the air pressure data every 10 seconds to eliminate the influence of random noise, so as to accurately determine whether the floor where the electronic device is located changes according to the air pressure variation of the air pressure data.
The electronic device can judge whether the floor where the electronic device is located changes according to the air pressure variation of the air pressure data.
Optionally, the electronic device may determine whether a floor where the electronic device is located changes by determining whether an air pressure variation within a preset time is greater than an air pressure threshold. For example, the preset duration may be 10 seconds, and is not particularly limited; the air pressure threshold may be an air pressure difference between two floors, such as 0.3 hectopascal (hPa). If the air pressure variation of the electronic equipment within a preset time is larger than the air pressure difference threshold, the floor where the electronic equipment is located can be considered to be changed.
Optionally, the electronic device may acquire air pressure data at a plurality of continuous preset durations, determine an air pressure maximum value and an air pressure minimum value in the air pressure data at each preset duration, and determine whether the floor where the electronic device is located changes according to whether a difference between the air pressure maximum value and the air pressure minimum value in the plurality of continuous preset durations is greater than an air pressure threshold. And if the difference between the maximum value and the minimum value of the air pressure in a plurality of continuous preset time periods is greater than the air pressure threshold value, judging that the floor where the electronic equipment is located is changed.
102. And when the floor where the electronic equipment is located is judged to be not changed any more according to the air pressure change quantity, identifying a reference air pressure value corresponding to the reference floor from the air pressure data, and identifying an end air pressure value corresponding to the floor change end point from the air pressure data.
The electronic equipment can judge that the floor where the electronic equipment is located does not change any more according to the air pressure variation. Optionally, when the air pressure variation of the electronic device within a preset time period is smaller than the air pressure threshold, it may be determined that the floor where the electronic device is located is not changed any more; or, when the air pressure variation of the electronic device within a preset time period is smaller than the air pressure threshold and the time for maintaining the air pressure data is longer than the time threshold, it can be determined that the floor where the electronic device is located is not changed any more.
The electronic device may identify a reference air pressure value corresponding to the reference floor and a terminal air pressure value corresponding to the floor change terminal from the air pressure data.
The reference floor may be a first floor of a building, and the reference air pressure value may be an air pressure value corresponding to the first floor of the building. The reference floor may be the first floor of an indoor environment or the first floor of an outdoor environment, which may be the first floor of an elevator entering the outdoor environment.
The floor change destination may be a floor that the electronic device finally arrives at after entering the indoor environment, and the destination air pressure value may be an air pressure value corresponding to the floor that the electronic device finally arrives at.
Optionally, the user of the electronic device may enter the floor change destination of the indoor environment through the elevator in the outdoor environment and the outdoor corridor, where the first floor of the elevator in the outdoor environment is the reference floor.
Alternatively, the electronic device may enter the first floor of the indoor environment from the outdoor environment, which is the reference floor, and enter the floor change destination of the indoor environment through the elevator or the staircase of the indoor environment.
The electronic equipment can judge whether the electronic equipment is in accordance with the GPS signal intensityFrom the outdoor environment into the indoor environment. For example, if the electronic device receives N GPS satellite signals with signal strengths { S1, S2, S3, … …, Sn }, respectively, the current GPS signal strength is
Figure BDA0003609581450000081
When S is less than the signal threshold S0, the electronic device is considered to have entered the indoor environment from the outdoor environment. For example, the signal threshold S0 may be 50, and is not limited.
Optionally, if the electronic device enters the floor change destination of the indoor environment from the elevator or the staircase in the indoor environment, the time when the GPS signal intensity is smaller than the signal threshold may be defined as the time T1 when the electronic device enters the indoor environment from the outdoor environment, and the air pressure value corresponding to the time T1 may be used as the reference air pressure value, that is, the position where the electronic device has just entered the indoor environment is used as the reference floor.
Alternatively, if the electronic device is a floor change destination entering the indoor environment from an elevator in the outdoor environment and an outdoor corridor, the time when the GPS signal strength is less than the signal threshold may be defined as the time T1 when the electronic device enters the indoor environment from the outdoor environment, and the air pressure data within a preset time period before the time T1 may be collected, where the preset time period may be 2 minutes. Because the air pressure value is reduced along with the increase of the floor height; as the floor level decreases, the air pressure value increases. If the floor where the electronic equipment is located is judged to be not changed any more according to the air pressure change amount within the preset time, a reference air pressure value and a terminal air pressure value can be determined from air pressure data collected within the preset time, the maximum value of the air pressure value within the preset time can be determined as the reference air pressure value, and the minimum value of the air pressure value within the preset time can be determined as the terminal air pressure value.
103. And determining a first target floor where the electronic equipment is located according to the starting point air pressure value and the ending point air pressure value, and acquiring a first wireless signal fingerprint corresponding to the first target floor.
The electronic device may determine a first target floor at which the electronic device is located based on the starting air pressure value and the ending air pressure value. The first target floor may be a floor where the electronic device is located after the floor change no longer occurs in the indoor environment, that is, floor information corresponding to the floor change destination.
The electronic device can calculate the height change Δ h of the electronic device from the reference floor to the floor change destination by the following formula.
Δh＝18410*(1+t/273.15)*(log10(p0)–log10(p1)) (1)
Wherein t is the current air temperature value and can be obtained from weather forecast; p0 is a reference air pressure value; p1 is the end point pressure value. From Δ h it is possible to calculate the number of floors changed f1, to mark the first target floor as-f 1 if f1<0 and as f1+1 if f1> 0.
The first wireless signal fingerprint may include a Media Access Control (MAC) address of a wireless signal source collected at the first target floor, and a signal strength received from the wireless signal source. The electronic device can start wireless signal fingerprint collection and collect a first wireless signal fingerprint at a first target floor. The wireless signal may be a WIFI signal, and is not limited specifically.
104. And storing the corresponding relation between the first wireless signal fingerprint and the first target floor into a wireless signal fingerprint library.
The electronic device can store the corresponding relation between the first wireless signal fingerprint and the first target floor into the wireless signal fingerprint library, namely the electronic device can store the first wireless signal fingerprint with the floor label information into the wireless signal fingerprint library by taking the first target floor as a label of the first wireless signal fingerprint. For example, when the electronic device enters a 3 rd floor of an indoor environment, the electronic device can acquire a wireless signal fingerprint corresponding to the 3 rd floor and store the wireless signal fingerprint into a wireless signal fingerprint database; if the electronic equipment moves from the 3 th floor to the 5 th floor, the electronic equipment can also acquire the wireless signal fingerprint corresponding to the 5 th floor and store the wireless signal fingerprint into a wireless signal fingerprint library. Therefore, the electronic equipment can automatically collect the wireless signal fingerprints corresponding to the floors frequently visited by the user in the process that the user uses the electronic equipment, a wireless signal fingerprint library can be efficiently generated, which is equivalent to the fact that each user can customize the wireless signal fingerprint library according to the floors frequently visited by the user, excessive floor information and wireless fingerprint information are avoided being stored, and the storage space of the electronic equipment is effectively saved.
105. When the electronic equipment is started, if the electronic equipment acquires the second wireless signal fingerprint, a second target floor matched with the second wireless signal fingerprint is determined from the wireless signal fingerprint database.
When the electronic device is not started on the first floor of the indoor environment but is started on other non-first floors, the floor where the electronic device is located cannot be directly calculated through the reference air pressure value and the terminal air pressure value because the reference air pressure value corresponding to the first floor cannot be obtained. However, since the user establishes the wireless signal fingerprint database in advance, when the electronic device is started on a non-first floor in an indoor environment, the electronic device can acquire a second wireless signal fingerprint corresponding to the floor where the electronic device is located, and determine a second target floor matched with the second wireless signal fingerprint from the wireless signal fingerprint database, wherein the second target floor is the floor where the electronic device is located currently. For example, when a user of the electronic device is working at the 5 th floor in a building, the 5 th floor is a floor where the user frequently goes, and therefore the wireless signal fingerprint library already stores the corresponding relationship between the floor and the wireless signal fingerprint corresponding to the floor, but the electronic device suddenly loses power, and after the electronic device is charged and restarted, the electronic device can collect the wireless signal fingerprint corresponding to the current floor, determine the floor information matched with the wireless signal fingerprint from the wireless signal fingerprint library, and finally determine that the current floor is the 5 th floor.
According to the embodiment of the application, the first target floor of the electronic equipment is determined according to the reference air pressure value and the terminal air pressure value, wireless signal fingerprint collection is started to obtain the first wireless signal fingerprint corresponding to the first target floor, and the corresponding relation between the first target floor and the first wireless signal fingerprint is stored in the wireless signal fingerprint database. For a subsequent scene that the electronic device is started in an indoor environment, for example, the electronic device is started in a non-1-floor of the indoor environment, even if the reference air pressure value of the 1-floor cannot be obtained and the floor where the electronic device is currently located is obtained through direct calculation of air pressure data, the second wireless signal fingerprint of the current floor can be acquired and matched in the wireless signal fingerprint library to obtain a second target floor matched with the second wireless signal fingerprint, wherein the second target floor is the floor where the electronic device is currently located. Therefore, the embodiment of the application can obtain the current floor information under the scene that the 1-floor reference air pressure value cannot be obtained, so that accurate floor positioning information is provided for users under diversified scenes.
In an application scenario, the embodiment of the application can be applied to a scenario in which information interaction is performed between an electronic device and other electronic devices, the electronic device can be connected or bound with the other electronic devices in advance, and the other electronic devices can be supervision terminals such as a mobile phone, a tablet computer or wearable devices connected or bound with the electronic device, so that a user of the supervision terminal can know floor change conditions of the user of the electronic device in time through the supervision terminals.
According to the embodiment of the application, the floor where the user arrives can be determined according to the air pressure data, the wireless signal fingerprints corresponding to the floor where the user is located are automatically collected after the electronic equipment is started, the wireless signal fingerprint library is generated according to the floor where the user is located and the corresponding relation of the wireless signal fingerprints, the worker does not need to collect the wireless signal fingerprints in advance, and accurate floor information can be obtained while a large amount of manpower and time cost are saved.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating another floor positioning method according to an embodiment of the present disclosure. As shown in fig. 2, the method comprises the steps of:
201. the method comprises the steps of obtaining air pressure data collected by an air pressure meter of the electronic equipment, and determining a first air pressure change amount corresponding to each sampling period according to a plurality of air pressure values included in an air pressure set corresponding to each sampling period.
The air pressure data comprises air pressure value sets respectively corresponding to a plurality of sampling periods; the set of air pressure values for each sampling period includes a plurality of air pressure values collected during each sampling period.
The sampling period may be 5 seconds, and is not particularly limited. During a sampling period, the electronic device may continuously collect a plurality of air pressure values, and treat the plurality of air pressure values in each sampling period as an air pressure set. The first air pressure change value may be an air pressure change value corresponding to each sampling period calculated from a plurality of air pressure values collected in each sampling period.
202. And identifying N continuous effective sampling periods from the plurality of sampling periods according to the first air pressure variation corresponding to each sampling period.
The first air pressure change amount corresponding to N continuous effective sampling periods is larger than a first air pressure threshold value; n is a positive integer greater than or equal to 1. For example, the first air pressure threshold may be 0.05hPa, which is not limited.
It can be considered that, within N consecutive effective sampling periods, the possibility that the floor where the electronic device is located changes is greater, because the first air pressure change amount corresponding to each effective sampling period is greater than the first air pressure threshold. Therefore, the continuous effective sampling periods can be identified from the plurality of sampling periods, and then the air pressure values in the continuous effective sampling periods are calculated to judge whether the floors of the electronic equipment in the continuous effective sampling periods change, so that the air pressure values in all the sampling periods can be prevented from being processed, and the operation efficiency of the electronic equipment is improved.
203. And judging whether the floor where the electronic equipment is positioned is changed or not according to a second air pressure variation between the maximum air pressure value and the minimum air pressure value in a plurality of air pressure values respectively corresponding to the N continuous effective sampling periods.
If a second air pressure variation between a maximum air pressure value and a minimum air pressure value in a plurality of air pressure values respectively corresponding to the N continuous effective sampling periods is larger than a second air pressure threshold value, determining that the floor where the electronic equipment is located is changed; and if the second air pressure variation is smaller than the second air pressure threshold, determining that the floor where the electronic equipment is located is not changed.
The second air pressure variation amount may be a difference between a maximum air pressure value and a minimum air pressure value among respective air pressure values in N consecutive valid sampling periods.
The second air pressure threshold may be an air pressure difference between two floors, such as 0.3hPa, and is not limited in particular.
Illustratively, if the sampling period is 5 seconds, N consecutive valid sampling periods are identified from the plurality of sampling periods, wherein the first air pressure variation corresponding to each valid sampling period is greater than a first air pressure threshold, such as 0.05 hPa. In N continuous effective sampling periods, recording the maximum air pressure value and the minimum air pressure value of a plurality of air pressure values in each effective sampling period, comparing the maximum air pressure value and the minimum air pressure value in each effective sampling period to obtain the maximum air pressure value and the minimum air pressure value in the N continuous effective sampling periods, calculating a second air pressure variation according to the difference between the maximum air pressure value and the minimum air pressure value, and if the second air pressure variation is greater than a second air pressure threshold value, such as 0.3hPa, determining that the floor where the electronic equipment is located is changed in the N continuous effective sampling periods.
204. And when the floor where the electronic equipment is positioned is judged to be not changed any more according to the air pressure change quantity, identifying a reference air pressure value corresponding to the reference floor and an end point air pressure value corresponding to the floor change end point from the air pressure data.
The electronic equipment can judge that the floor where the electronic equipment is located does not change any more according to the air pressure change quantity.
