Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a method for monitoring a mobile device, where as shown in fig. 1, the method is applied to a wireless signal transmitting device 001, the wireless signal transmitting device 001 is disposed in a preset monitoring area 002, and at least one mobile device 003 located in the preset monitoring area 002 is connected to the wireless signal transmitting device 001 in a wireless communication manner, and as shown in fig. 2, the method may include:

S400, determining whether the mobile device 003 is about to leave the preset monitoring area 002 according to at least two of the signal strength, the rate of change and the trend of change.
The method shown in fig. 2 may determine whether the mobile device is about to leave the preset monitoring area by acquiring the signal strength of the wireless signal of the mobile device, the signal strength change rate of the wireless signal, and the signal strength change trend of the wireless signal, and according to at least two of the three parameters of the signal strength, the change rate, and the change trend. The signal intensity, the signal intensity change rate and the signal intensity change trend can reflect the distance, the moving speed and the moving direction between the mobile equipment carried by the user and the wireless signal sending equipment, so the mobile equipment can be accurately monitored and the mobile equipment which is about to leave a preset monitoring area can be determined.
The execution sequence of steps S100, S200, and S300 shown in fig. 2 is only an optional sequence, and the execution sequence of steps S100, S200, and S300 is not limited in the embodiment of the present invention, and steps S100, S200, and S300 only need to be executed before step S400.
Alternatively, the method shown in fig. 2 may be applied to the first electronic device 004, and the steps S100 to S400 are performed by the first electronic device 004. The first electronic device 004 may be a computer, and the first electronic device 004 may be communicatively connected with the wireless signal transmitting device 001. In other embodiments, further, the first electronic device 004 may be communicatively coupled with the mobile device 003.
Optionally, in an optional embodiment of the present invention, when the mobile device 003 enters the preset monitoring area 002, the mobile device 003 establishes a wireless communication connection (e.g., a bluetooth connection) with the wireless signal transmitting device 001 by scanning the two-dimensional code. Of course, in other embodiments, the mobile device 003 can also queue for a number by scanning the two-dimensional code (e.g., queuing for a number at a bank outlet). Of course, during the process of making communication connection between the wireless signal transmitting device 001 and the mobile device 003, the electronic device executing the method shown in fig. 2 of the present invention can obtain the information about the mobile device 003 in communication connection with the electronic device through the wireless signal transmitting device 001, such as: the radio signal strength between the mobile device 003 and the radio signal transmitting device 001, queue information of the mobile device 003, and the like.
In practical applications, an alternative embodiment of the present invention may only perform two of steps S100, S200 and S300, and if step S400 detects that the mobile device 003 is about to leave the predetermined monitoring area 002 according to the signal strength and the rate of change of the signal strength, the present invention may only perform steps S100 and S200 without performing step S300.
Of course, in another alternative embodiment, step S400 may be performed after the three steps S100, S200 and S300 are performed.
The wireless signal transmitting device 001 according to the embodiment of the present invention may be an electronic device having a bluetooth signal transmitting function or an electronic device having a Wi-Fi signal transmitting function. The electronic device with the bluetooth signal transmitting function may be: cell-phone, personal computer, panel computer, intelligent wearing equipment etc. certainly, above-mentioned electronic equipment with bluetooth signal emission function can also be: and a Bluetooth transmitting and receiving device. The electronic device with Wi-Fi signal transmission function may be a wireless router, a wireless signal transmitter, etc.
In practical applications, the method for monitoring the mobile device 003 provided by the embodiment of the present invention is used for determining the mobile device 003 about to leave the preset monitoring area 002. The preset monitoring area 002 may be an indoor closed irregular area or an outdoor open area.
As shown in fig. 3, 4 and 5, each of fig. 3, 4 and 5 is a schematic layout diagram of a wireless signal transmitting device, in practical application, a signal coverage area of the wireless signal transmitting device 001 may cover a preset monitoring area 002, and the signal coverage area of the wireless signal transmitting device 001 may keep a certain distance from an outlet of the preset monitoring area 002, where the distance may be adjusted according to a practical application scenario and power of the wireless signal transmitting device 001.
Optionally, the arrangement shown in fig. 3 is adopted, so that the signal coverage area of the wireless signal transmitting device 001 can cover more building areas of the preset monitoring area 002, and the arrangement has the advantage that the investment cost can be reduced.
Optionally, the arrangement shown in fig. 4 is adopted, so that the signal coverage of the wireless signal transmitting device 001 can cover more building areas of the preset monitoring area 002, and more mobile devices 003 can be connected at the same time. The arrangement mode has the advantages that the monitoring area is larger, the number of the mobile devices 003 is increased, and the effect of increasing the customer reception capacity is achieved.
Optionally, the arrangement mode as shown in fig. 5 is adopted, so that the signal coverage area of the wireless signal transmitting device 001 can cover more building areas of the preset monitoring area 002, and meanwhile, since a plurality of wireless signal transmitting devices 001 are arranged, the mobile device 003 can be continuously monitored conveniently. The arrangement mode has the advantages that the uninterrupted monitoring of the mobile device 003 can be realized, and the monitoring effect is better.
The embodiment of the invention can be applied to the same plane area, such as the office area of the same floor, a banking hall and the like; the method can also be applied to areas in three-dimensional space, such as office areas with multiple floors, office buildings and the like. The arrangement of the embodiment of the invention in the three-dimensional space area can divide each floor into a plane area, and then the arrangement of the embodiment of the invention in the same plane area is correspondingly adjusted.
Optionally, the wireless signal transmitting device 001 may be disposed at any position in the preset monitoring area 002, and the specific position is set according to an actual application scenario, which is not limited herein.
It should be noted that, when the present invention is used for predicting the movement within the monitoring region 002, since the movement distance of the mobile device 003 in the horizontal direction is large and the movement distance in the height direction is small, the present invention can simplify the movement of the mobile device 003 in the three-dimensional space to the movement in the horizontal direction. Namely: the movement of the mobile device 003 in the height direction is ignored. Of course, this approach may cause small errors in the positioning results of the mobile device 003. To reduce this error, the present invention may set the wireless signal transmitting apparatus 001 within a normal range of the mobile apparatus 003 in the height direction. For example: the mobile device 003 is a mobile phone, and a conventional movement range of the mobile phone held by the user in the height direction is 0.8 m to 1.2 m, and considering a practical application scenario, the height of the indoor counter is 0.9 m to 1.1 m, and preferably, the present invention may set the wireless signal transmission device 001 at an intermediate height within the above-mentioned conventional movement range, for example, may set the wireless signal transmission device 001 at a height of 1 m.
Where the mobile device 003 can be an electronic device that the user often attaches to him or her, including but not limited to: the mobile phone, the tablet personal computer, the PC and other devices or the intelligent wearable devices such as the intelligent bracelet and the like.
In practical applications, the wireless signaling device 001 may first establish wireless communication with the mobile device 003 to obtain the identity of the mobile device 003 and communicate based on the recorded device identity. Specifically, the wireless signal transmitting apparatus 001 may transmit a wireless signal to the matched mobile apparatus 003 at a preset time period. The wireless signal sent by the wireless signal sending device 001 may be various, such as bluetooth, radio frequency identification, Wi-Fi, and the like. The content of the wireless signal transmitted by the wireless signal transmitting device 001 may be arbitrary, and the present invention is not limited herein.
The wireless signal transmission device 001 may have a wireless signal reception function, and may receive a wireless signal transmitted from the mobile device 003 connected thereto by wireless communication and determine the intensity of the wireless signal. Of course, the mobile device 003 may detect the intensity of the wireless signal transmitted from the wireless signal transmission device 001 to the mobile device 003, and then the mobile device 003 transmits the intensity to the wireless signal transmission device 001. Thus, the wireless signal transmitting apparatus 001 obtains the signal strength of the wireless signal between the mobile apparatus 0003 and the wireless signal transmitting apparatus 001.
The signal strength of the wireless signal has a certain mathematical relation with the distance, and the distance between the mobile equipment and the wireless signal sending equipment can be determined through the signal strength.
In practical applications, there are various methods for determining the distance between two devices according to the signal strength between the two devices, and one of the following methods is provided as an example:
by the formula
D＝10^[(abs(RSSI)-A)/(10*n)]
And calculating the distance D between the mobile equipment and the wireless signal transmitting equipment, wherein RSSI is the signal strength of a wireless signal (the wireless signal is transmitted by the wireless signal transmitting equipment) received by the mobile receiving equipment, A is the signal strength of a wireless signal (the wireless signal is transmitted by the wireless signal transmitting equipment) obtained by the mobile equipment when the mobile equipment and the wireless signal transmitting equipment are separated by a reference distance, and n is an environment attenuation factor.
Alternatively, the reference distance may be a predetermined distance, such as 1 meter. As can be seen from the above right equation, when the environmental attenuation factors in a certain monitoring area are the same, the distance D between two devices is only related to the signal transmitted between the two devices and the signal strength.
After receiving the signal strength of the wireless signal between the mobile device 003 and the wireless signal transmitting device 001, the wireless signal transmitting device 001 may repeat step S100 at certain time intervals to obtain the signal strengths at multiple times, and the wireless signal transmitting device 001 transmits the signal strengths at the multiple times to the first electronic device 004 for monitoring the mobile device 003, where the first electronic device 004 may calculate the signal strength change rate and the signal strength change trend of the wireless signal at each time interval according to the signal strengths at the multiple times.
It is understood that the signal intensity change rate obtained in step S200 may reflect the moving speed of the mobile device 003 within the preset monitoring region 002. When the signal intensity change rate is increased, the mobile device 003 is rapidly moving; when the rate of change of signal strength decreases, it indicates that the mobile device 003 is moving slowly.
It is understood that the signal intensity variation trend obtained in step S300 may reflect the moving direction of the mobile device 003 within the preset monitoring region 002. When the signal intensity variation trend is increased, it indicates that the mobile device 003 is approaching the wireless signal transmission device 001; when the trend of the signal strength variation decreases, it indicates that the mobile device 003 is moving away from the wireless signal transmitting device 001.
Alternatively, in an alternative embodiment of the present invention, the signal strength change rate is a scalar, and step S400 may include determining mode one,
the first determination method is as follows: according to the signal intensity, determining the distance between the mobile device 003 and the wireless signal transmission device 001, when the distance between the mobile device 003 and the wireless signal transmission device 001 is greater than a preset distance threshold and the signal intensity change rate is greater than a preset change rate threshold, determining that the mobile device 003 is about to leave a preset monitoring area 002, wherein the preset distance threshold is less than a first distance: the distance between the wireless signal transmitting device 001 and the exit of the preset monitoring area 002.
It is understood that when the distance between the mobile device 003 and the wireless signal transmitting device 001 is greater than the preset distance threshold, the distance between the mobile device 003 and the wireless signal transmitting device 001 is far; when the signal intensity change rate is greater than the preset change rate threshold, it indicates that the moving speed of the mobile device 003 is fast. In this case, the mobile device 003 may be about to leave the preset monitoring region 002.
