Indoor GPS or big-dipper satellite location technology
GPS or the Big Dipper are the location technologies be most widely used at present.When receiver is in office work, due to signal large high attenuation by the impact of buildings, positioning precision is also very low, wants to reach that outdoor is equally direct from satellite broadcasting, extracts navigation data and temporal information is impossible.
Indoor wireless location technology
Along with the development of wireless communication technology, emerging radio network technique, such as wifi, zigbee, bluetooth, infrared ray, ultrasound wave and ultra broadband etc., be widely applied in indoor positioning.But all more or less there are some defects in above-mentioned location technology.As Infrared Transmission affects larger apart from short, location by barrier.Ultrasound wave affects very large by multipath effect and non-line-of-sight propagation, need a large amount of bottom hardware facility investments, cost is too high simultaneously.
Except above-mentioned location technology, also have base what computer vision, light track and localization, the graphical analysis of base what, magnetic field and beacon location etc.In addition, the location technology, beacon location, triangle polyester fibre etc. of the graphical analysis of base what is also had.No matter GPS location technology or utilizing WSN or other positioning means to enter location has its limitation, and can not be directed.The trend of following indoor positioning technologies is that multiple location technology combines, ultrasound wave location technology and wireless location technology are organically combined, plays respective excellent length, then both can provide good precision and response speed, wider scope can be covered again, realize seamless, locate accurately.
Summary of the invention
In order to overcome the defect that above-mentioned existing method exists, the invention provides a kind of indoor positioning orientation method based on wifi, ultrasound wave and large data analysis technique.The advantage of various localization method can merge by it, overcomes the shortcoming of various localization method, realizes accurate, quick, large space hi-Fix and orientation.
For solving the problem, the present invention adopts following methods: a kind of indoor orientation method based on wifi, ultrasound wave and large data analysis technique, comprises wifi emitter, ultrasonic transmission device, wifi receiving trap, ultrasonic probe, ultrasonic receiver, signal storage device, signal processing apparatus, location output unit.
It is characterized in that, described wifi emitter, is arranged in indoor diverse location, for launching wifi signal; Also have wifi emitter to be arranged on the object of needs location simultaneously, while transmitting wifi signal, carry the instruction whether starting ultrasound wave and launch.
Described ultrasonic transmission device, is arranged in indoor diverse location, and for launching ultrasonic signal, it is launched hyperacoustic instruction and controls by wifi signal.
Described wifi receiving trap, is arranged in the front-end and back-end of the object needing location, for receiving the signal that wifi emitter is launched, while realization location, determines object moving direction.Also be arranged in ultrasonic transmission device, for receiving the instruction starting ultrasound wave and launch simultaneously.
Described ultrasonic probe, ultrasonic receiver, is arranged in the front-end and back-end of object needing location, for receiving the signal that ultrasonic transmission device is launched, while realization location, according to the difference of front end and back segment Received signal strength, determines object moving direction.
Described signal storage device, stores ultrasound wave and wifi signal.
Described signal processing apparatus, processes the ultrasonic signal and wifi signal that are stored in signal storage device, to different device transmission of signals.
Described location output unit, the wifi signal that the object of locating as required collects and ultrasonic signal, the model generated according to large data analysis module, exports positional information and the direction of motion information of object.
Described large data analysis module, utilizes large data analysis technique, carries out data scrubbing, training pattern, model checking and model generation to signal.
The invention has the beneficial effects as follows: play the respective advantage that ultrasonic positioner precision is high, wifi locating device scope is wide, according to circumstances utilize ultrasonic positioner to correct position, namely do not need ultrasonic positioner to work always; Wifi locating device then uninterruptedly can send locating information always, only just asks ultrasound wave location when needs precise position information.In addition, due to ultrasonic positioner complex and expensive, wifi locating device simple cheap, do low collocation like this, the solution of a set of economy can be effectively provided.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is system architecture schematic diagram of the present invention;
As shown in Figure 1, data are transmitted by wireless or wired mode between each device.
1. signal processing apparatus sends instruction, and multiple (two or more) wifi emitter that notice is positioned at diverse location sends wifi signal, simultaneously notice be positioned at anchor point two (or more) signal receiving device receives wifi signal.
2. received wifi signal is all stored in signal storage device.
3. anchor point moves, and receives the wifi signal of different anchor point, can require optional m igration step-length according to location accuracy.
4. select accurate anchor point, ultrasonic signal launched by signal processing apparatus notification signal emitter, meanwhile, signal receiving device prepares received ultrasonic signal, determine the distance between ultrasonic transmission device and receiving trap according to the mistiming again, and range information is kept at signal storage device.
5., after the wifi signals collecting of all anchor points, large data analysis module starts to carry out data cleansing, model training, model checking, model generation to wifi signal.
6. because the receiving trap of anchor point is in two or more, and lay respectively at the front-end and back-end of advance route, therefore according to the signal difference of two acceptance points, the working direction of positioning object can be analyzed.
7., when needs are located, only need to read two wifi Received signal strength on positioning object, then calculated by model, the Position Approximate of object can be known; If need accurately to locate object, only need notice ultrasound wave transmitter module to launch ultrasound wave, measure the distance between positioning object and ultrasonic transmission device, then calculate can draw by model.
Be ultrasound wave dispensing device and ultrasonic probe, ultrasonic receiver functional schematic as shown in Figure 2, the function of wifi transmitting and receiving trap is similar with it, repeats no more herein.
In figure, single-chip microcomputer is core control portions, according to the working method of setting, produces the square wave of certain frequency, and drive ultrasonic generator to send cluster signal through overdrive circuit, single-chip microcomputer now starts timing.
Receiving loop is resonant tank, the weak echo signal received is detected, and send signal amplification circuit to amplify, receive generation pulse output and send singlechip interruption end, single-chip microcomputer stops timing after receiving look-at-me, calculates distance value, preserves and waits for reading or direct through sending.In receiving course, the gain of single-chip microcomputer timing controlled amplifying circuit, improves gradually, to adapt to distance more weak echoed signal more far away.
