Abstract
The invention discloses a positioning system with a plurality of receivers, which comprises two or more receivers distributed in a positioning region, wherein when a signal for positioning, emitted by an emitter, is received by one or more of the receivers, position information of the emitter can be figured out. According to a low-cost and simple method disclosed by the invention, a positioning region is enlarged based on the prior art, problems of easiness in interference and attenuation on a positioning signal are made up, and positioning accuracy can be improved.
Description
Technical field
The present invention relates to a kind of signal that utilizes and carry out the relative positioning method, belong to information processing and signal Processing field.
Background technology
The receiver that general existing electronic range measurement principle is a signal is distributed in locating area, after the signal that is used for locating of transmitter emission is received one or more the receiving of device, just can calculate the positional information of transmitter.The signal that is used to locate generally has ultrasound wave, infrared, laser, radiofrequency signal.Based on different principle, transmitter and receiver combine sometimes.
When present disclosed digital pen product can write on common paper, paint, person's handwriting is shown on computers truly, be implemented on the computer then and edit arbitrarily, store, print, be widely used in various fields and occasions such as electronic teaching, meeting speech.Wherein in the digital pen system based on the ultrasound wave principle, the basic emitting head that uses is launched ultrasonic signal in air, the time that other has a receiver to arrive according to ultrasound wave, calculate the relative distance of emitting head and receiver again according to three angle positioning methods, shortcoming is that the noise of environment to external world is very responsive, ultrasound wave is decayed very big in transmission, causes using in large-sized working range.
Summary of the invention
The purpose of this invention is to provide cheap and simple method, enlarge locating area, remedy positioning signal and be subject to the problem disturbing and decay, improve locating accuracy based on prior art.
In this positioning system with a plurality of receivers, at least contain two of two signal receivers and be distributed in locating area, after the signal that is used for locating of transmitter emission is received one or more the receiving of device, just can calculate the positional information of transmitter.The positioning signal that is to say transmitter emission can be received the back by a receiver and just can finish position fixing process, be finished position fixing process after also can being received by two or more receivers, and receiver whether may to receive positioning signal be working range and sensitivity decision by receiver; The orientation range of a plurality of receivers necessarily has lap, and lap can be arranged in twos, also can three receivers or more a plurality of receiver between overlapping (back claims multiple folded), but also promptly use overlapping in twos and multiple folded combination.
This has the positioning system of a plurality of receivers, each receiver can be one and have that complete signal receives and the receiver of processing capacity, and the locating information that the processing positioning signal is obtained is transferred to and draws emitter position information after a signal processor (as computer) is handled again; Each receiver can be a positioning signal sensor, can receive the signal that is used to locate of transmitter emission, after the signal that is used for locating of transmitter emission is by two or more the receiving of sensor, just can calculate the positional information of transmitter.Each receiver is a simple positioning signal receiver sensor, does not have signal processing function, need focus on the positional information that draws transmitter again to positioning signal concentration of transmissions to a signal processor.
This has the positioning system of a plurality of receivers, can enlarge the positioning system locating area by increasing receiver as far as possible, and it is placed in different positions, and the location lap that as far as possible makes each receiver is for minimum.These receivers can be placed on the same straight line of locating area, also can be not on same straight lines, but require the orientation range of a plurality of receivers that lap is necessarily arranged, and lap can be arranged in twos, also can be all overlapping.
This has the positioning system of a plurality of receivers, and it can be applied to writing and controlling of electronic whiteboard, by the mode of receiver cascade, makes the scope of writing of electronic whiteboard unrestricted in theory.Perform region between receptacle overlapping areas in twos is A square metre, if a receiver can be operated in the B square metre of scope, two receivers just can nearly reach in the 2*B-A square metre of scope, adopt n receiver just to work in n*B-A square metre of scope nearly.Can easily learn,, adopt the scope of writing of the electronic whiteboard of the method to enlarge always by the number of continuous increase receiver.
This has the positioning system of a plurality of receivers, and the positioning signal of transmitter emission can have ultrasound wave, infrared, laser, radiofrequency signal.Because minding, the present invention do not use which kind of concrete grammar in the scope of a receiver, to position, how major concern enlarges orientation range by a plurality of receivers, so the mode that signals such as known passing through is ultrasonic, infrared, laser, radio frequency position just can enlarge orientation range simply after adopting the method.
Be divided into two kinds of situations below and describe, first kind of situation is that each receiver can be a receiver with complete signal reception and processing capacity; Second kind of situation is that each receiver is a simple positioning signal receiver sensor.
When each receiver can be the receiver with complete signal reception and processing capacity, need before using native system, calibrate.Some calibration points of calibration usefulness must be chosen in the overlapping locating area of a plurality of receivers.Adopted the positioning system of the method necessarily need calibrate, otherwise the locating information that each receiver is exported can it doesn't matter, thereby can't position in the locating area after expansion.And by transmitter lap emission positioning signal between receiver, a plurality of receivers obtain different locating information respectively after receiving same positioning signal, by calculating, thereby just obtained each receiver of positioning system and enlarged the calibration value that locate the back, use this calibration value just can revise this positioning system, thereby draw the positional information of transmitter.
What need indicate is, this locator meams is different from general Cellular Networks locator meams, be because the Cellular Networks location need be according to the distance between several acceptance points and the transmitter, calculate the position of transmitter again by the circular arc joining, this signal that just requires to have at least 3 acceptance points to receive transmitter simultaneously could be located, and promptly can finish the location and the present invention only needs a receiver to receive signal.
When each receiver is a simple positioning signal receiver sensor and Cellular Networks location is similar, but requires these receiver sensors all to be connected to or the input of gating element, and acceptor circuit is connected on or the output of door.
When the signal of transmitter is received by the sensor more than two or more sets, be connected to or the input of gating element at each group sensor, and acceptor circuit is connected on or the output of door, sensor is pressed the putting position numbering, the sensor of odd-numbered all insert one or, the sensor of odd-numbered all inserts another or door, these two or insert processor again and handle, learn it is which receiver receives signal by numbering in addition, so just can position process, concrete connected mode is referring to Fig. 4.
The coordinate of first sensor of transmitter is reference coordinate zero point, connect second sensor and can determine the coordinate of second sensor along the upper edge of above-mentioned blank or LCD after stretching with the electric wire that definite length is arranged, when using more multisensor, analogize, so just do not need extra calibration process.
