Description
Technical field
The present invention relates to RSSI detection technique field, particularly relate to a kind of method obtaining wireless device MAC Address and signal intensity RSSI value.
Background technology
At present, along with the development of wireless location technology, indoor positioning technologies becomes the focus that people pay close attention to. Existing indoor positioning technologies mainly has: light track and localization technology, A-GPS location technology, ultrasonic locating technology, WiFi technology etc. Location technology based on WiFi has wide coverage, and information transfer rate is fast, it is achieved the concern of the advantage extremely people such as less costly.
Existing mobile positioning technique is according to its applied environment, substantially can be divided into two classes: a class is outdoor positioning technology on a large scale, mainly has several as follows: GPS positioning mode, cellular unit mark (Cell2ID) positioning mode, TOA positioning mode, TDOA positioning mode, AOA positioning mode, AOA/TOA mixed location method etc.; Another kind of is short distance indoor positioning technologies, typical in light tracing-positioning system, A2GPS location, radio wave and ultrasound wave integrated positioning, REID (RFID) and RSSI location etc.
Light track and localization generally requires that the linearly of followed the tracks of target and detector is visual and tracking target is opaque, by the collaborative work of fixing infrared camera and a lot of infrared light-emitting diode, completes track and localization. Due to its technical characterstic, high-precision light projection to be realized, it is desirable to possess the equipment of complexity and costliness. A2GPS is a kind of improvement GPS location technology that may be used for indoor, and it requires integrated gps receiver in mobile phone and the delay code that the substantial amounts of related device parallel search of need is possible, completes location. Due to the price of present stage GPS and embed it in the technical costs in mobile phone, determine the restricted gender of A2GPS application. Radio wave and ultrasonic synergistic location technology utilize the time difference of electromagnetic transmission and sonic transmissions to find range, and precision is higher and less costly, and determining it has certain market potential. But its measurement distance is shorter and sound absorption phenomena impair can be occurred to range measurement accuracy, if needing to realize the location of relatively long distance, it is necessary to extend out multistage amplifier circuit in ultrasound probe front end. Radio-frequency recognition system is mainly made up of three parts: electronic tag, card reader and transmit the miniature antenna of radiofrequency signal between label and card reader. When label is placed in after card reader sends and obtain energy near the electromagnetic field of fixed frequency and produce electrification reset, originally it is in the label of " resting state " to be activated and will modulate containing message codes such as self category identification code mark, manufacturer logos carrier wave is launched through card internal antenna, processes identification for card reader.
Generally, the position error of A2GPS is within the scope of 5��50 meters; RFID, light are followed the tracks of and hyperacoustic position error is within 1��2 meter. Wherein, radio wave and ultrasonic synergistic location, precision higher up to several centimetres to the order of magnitude of tens centimetres on. Require that the precision of Location Based Service to reach, within 50 meters, to reach within 150 meters when 95% when 67% according to FCC (FCC). Therefore, above-mentioned several alignment systems all can apply to the location of real system, but when practical application, it is necessary to balance cost is selected with demand.
In above-mentioned indoor positioning technologies, also having one is RSSI location technology. It is to utilize electromagnetic wave in transmitting procedure, and received signal power intensity and transmission range also exist certain variation relation, find out this variation relation in specific environment, just can be used for positioning. At present, many wireless chips that transmit/receive can provide RSSI detected value, as long as can communicate between chip in principle, it becomes possible to estimate distance therebetween. So, based on the location of RSSI, when positioning for real-time system, very convenient. But owing to being subject to the obstruction of the barriers such as various objects such as floor, wall and human body, electromagnetic wave can also exist reflection, diffraction and diffraction so that RSSI value change at random is bigger. Therefore, adopting a small amount of beaconing nodes to carry out RSSI location, often positioning precision is not high.
Comparatively rough due to gps location, and undesirable in particular space inner position effect, and particularly indoor positioning this part, gps cannot be accurately positioned substantially. The technical scheme of present main solution indoor positioning has bluetooth, ZigBee, bluetooth realizes location mainly by ibeacon, ZigBee mainly uses particular communication agreement to carry out computed range, and wireless location mainly relies on acquisition IEEE802.11 communications protocol to position. Bluetooth location needs to develop specific mobile phone app and positions, and ZigBee needs specific hardware to position, and wireless location needs equipment actively to connect wireless network.
