Abstract
The invention provides a household indoor WIFI (wireless fidelity) handheld object finding device, which is used for helping a user to quickly find the self object. The household indoor WIFI handheld object finding device consists of handheld mobile WIFI object finding equipment with small size and one or a plurality of wireless tag equipment with smaller size, wherein the handheld mobile WIFI object finding equipment is a WIFI accessing point and comprises a WIFI receiving and sending module, an antenna, a display module, a microprocessing module, a sound module, an input module and the like; a wireless tag is a wireless information point and comprises a microprocessing module, a WIFI receiving and sending module, an antenna, a sound module and the like. The household indoor WIFI handheld object finding device has the advantages that the wireless tag is attached to the back surface of the object, and the WIFI connection is established between the handheld mobile WIFI equipment and the wireless tag when the user needs to find the object; the user can specify the special wireless tag (corresponding to the to-be-found object) to send the sound; according to the signal intensity of the wireless tag, the handheld equipment is used for estimating the distance away from the wireless tag, and displaying the distance on a screen; when the user moves, the change of the distance is also displayed on the screen; the user can quickly find the self object according to the distance and sound information.
Description
Technical field
The application relates to the indoor device for searching article of a kind of simple type domestic based on WIFI.
Background technology
In daily life, we often can encounter, and thing is placed on family, but can not remember situation where, such as car key, wallet, certificate, long-term no data etc.By this WIFI device for searching article, we wish the thing that people can be helped to find oneself quickly.WIFI is widely used in indoor environment now, operates mainly in 2.4G and 5G frequency, and wherein 5G is comparatively not easy the interference being subject to other wireless device.WIFI can also support that multiple information point is linked into an access point simultaneously.
Summary of the invention
The object of the invention is to, the hand-held device for searching article of a kind of WIFI of indoor is provided, help user to find the thing of oneself fast.This device is made up of look for something equipment and the less wireless tag device of one or more volume of the hand-held mobile WIFI of a small volume.Wireless identification tag is attached to the back side of object, when user needs to find article time, uses hand-held WIFI equipment to set up WIFI with wireless identification tag and is connected.User can specify specific wireless identification tag (in requisition for the object found) to send sound.According to the signal intensity of wireless identification tag, handheld device roughly estimates the distance oneself arriving wireless identification tag, and is presented on screen, and when user's movement, distance change is also reflected on screen.User, by Distance geometry acoustic information, just can find the thing of oneself fast.
This device comprises the hand-held mobile WIFI equipment of a small volume and the less wireless tag device of one or more volume.Hand-held mobile WIFI equipment and WIFI access point, comprise WIFI transceiver module, antenna, display module, micro treatment module, sound module, load module etc.WIFI transceiver module, antenna is used for launching, and receives WIFI signal; Micro treatment module is for analyzing WIFI signal intensity, and estimation approximate distance is also reflected on display screen; Enter key is used for user and sets article and corresponding wireless identification tag, when finding thing, specifies the wireless identification tag (i.e. object) oneself needing to find by enter key.Wireless identification tag and wireless messages point comprise micro treatment module, WIFI transceiver module, antenna, sound module.WIFI transceiver module, antenna is used for launching, and receives WIFI signal; The instruction that micro treatment module is sent for the treatment of WIFI access point, sound module sends sound, and user can judge the position of label according to sound source.
Advantage of the present invention is WIFI handheld device, and wireless identification tag is smaller and more exquisite, and be easy to carry about with one use, is particularly suitable for family and uses; Wireless identification tag needs certification when connecting handheld device, and communication data is through encryption, safer; A set of product can use multiple wireless identification tag, and the corresponding multiple object of label, is applicable to easily forgetful crowd.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of apparatus of the present invention embodiment.
Fig. 2 be apparatus of the present invention product schematic diagram.
Embodiment
When user uses equipment to find, the hand-held equipment of looking for something (i.e. access point) of WIFI, wireless identification tag (i.e. information point) all sends wireless signal with firm power.Wireless messages point joins the services set indications SSID of WAP issue by certification, Data Packet Encryption communication each other.User can select the object (posting wireless identification tag behind) needing to find on a handheld device, allows this wireless identification tag send lasting sound, until find.
WAP adds up the wireless messages point of access SSID simultaneously, the wireless signal strength received by the MAC Address record that the other side is unique, estimation distance each other, and is presented on screen.Algorithm is as follows:
Signal is sent in information point, time access point receives signal, the constant transmit power of Given information point, antenna gain; The received power sky of access point, line gain, we can calculate spatial attenuation:
free space path Loss=|Transmit Signal (information point Tx)+Gain(information point antenna)+Gain(access point antenna)-Received signal (access point) |
After obtaining spatial attenuation, the frequency (2.4G or 5G) of known WIFI, uses the equation of exterior space decay, calculates distance between the two:
Loss（dB)=20log(d)+20log(f)-27.55
d=10^{[Loss+27.55-20log(f)]/20]}
Loss in formula is exactly spatial attenuation, and linear module is dB; D is access point and information point distance, and linear module is m; F is frequency 2.4G or the 5G of WIF use, and linear module is MHz; Gain is antenna gain, and unit is dB, Transmit Signal is the signal intensity that information point sends, and unit is dB, Received Signal is the signal intensity that access point receives, and unit is dB.
It should be noted that this algorithm is mainly applicable to the few ecotopia of disturbing factor.Indoor interference many factors, especially concrete, fragment of brick, the decay that metal frame can cause signal a large amount of, refraction etc.Likely label is just within 2 meters, but in other room, central just every wall, the signal causing the hand-held equipment of looking for something to receive is very weak even not to be had.Can preset in the handheld device, if signal attenuation is too large or do not have signal, screen can point out object that user looks for may in other room, and user can arrive searching in other room.
User knows the approximate distance of hand-hold wireless access point apparatus to wireless tag information point from screen.When user's movement, distance change is also reflected on screen.User by the position of Distance geometry sound adjustment oneself, can finally find object and wireless identification tag.
