Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
Step ground detailed description.Only this is stated, the present invention occurs in the text or will occur up, down, left, right, before and after, it is inside and outside etc. just
Position word is not to specific restriction of the invention only on the basis of attached drawing of the invention.
Fig. 1 is the overview flow chart of the indoor orientation method the present invention is based on infrared ray, comprising:
S100, mobile transmitting terminal transmitting are modulated infrared；
S200, the reception of infrared receiver end group are modulated infrared, and transmit signal data to controller；
S300, controller calculate the position of mobile transmitting terminal according to signal data.
It should be noted that the indoor orientation method based on infrared ray passes through record infrared ray emission time and each infrared
At the time of line receiving end receives, the time that infrared ray travels to each infrared receiver end from mobile transmitting terminal is calculated, is then tied
Close the constant principle of infrared linear velocity (light velocity), calculate infrared ray from mobile transmitting terminal travel to each infrared receiver end away from
From, that is, move transmitting terminal to each infrared ray distance.When the quantity of infrared receiver is three, and three infrared rays are connect
Receipts device is in same plane but not in same straight line, i.e. three infrared receiver interconnecting lines form triangles, can pass through
Transmitting terminal to each infrared receiver end distance and each infrared receiver end mutual distance are moved, mobile transmitting is uniquely determined
End ground three-dimensional position.
The indoor orientation method the present invention is based on infrared ray is specifically described below.
As shown in Fig. 2, the specific steps that mobile transmitting terminal emits modulated infrared (S100) include:
S101, record infrared ray emission time；
S102, the electric signal comprising infrared ray launch time information is modulated into infrared ray；
S103, transmitting are modulated infrared.
The emission time of infrared ray is important parameter.Some indoor orientation methods pass through the transmission technologys such as radio frequency, bluetooth
Directly to the emission time of controller transmission infrared ray, although such transmission method is simple directly, but to be sent out mobile
The transmitting equipment of the signals such as end installation radio frequency, bluetooth is penetrated, controller end will also install corresponding reception device, different types of letter
Number transmission may influence infrared signal, cause " signal noise ", also increase the complexity of positioning device.The present invention is based on
The indoor orientation method of infrared ray takes another transmission method.As shown in Fig. 2, when mobile transmitting terminal emits infrared ray every time,
Infrared ray emission time is first recorded, the electric signal of infrared ray emission time is then modulated into infrared ray, so that launch
Infrared ray itself carries important information, without still further emitting other signals again, infrared ray will occur and signal transmission combines
Together, reduce " signal noise ", also reduce the complexity of positioning device.
As shown in figure 3, infrared receiver end group receiving infrared-ray signal, and the step of transmitting signal data to controller
(S200), comprising:

It should be noted that during actual operation, each infrared receiver end of infrared receiver end group be it is independent into
Row above-mentioned steps.
For example infrared receiver end group 200 contains four infrared receiver ends, is the first infrared receiver end, respectively
Two infrared receiver ends, third infrared receiver end and the 4th infrared receiver end.When the mobile transmitting of transmitting terminal 100 modulation is infrared
When line, then infrared receiver end group 200 has following process:
First infrared receiver end receives modulated infrared, first time of reception of record, demodulates infrared ray and simultaneously records infrared
Line emission time transmits infrared ray emission time, first time of reception to controller；
Second infrared receiver end receives modulated infrared, second time of reception of record, demodulates infrared ray and simultaneously records infrared
Line emission time transmits infrared ray emission time, second time of reception to controller；
Third infrared receiver end receives modulated infrared, the record third time of reception, demodulates infrared ray and simultaneously records infrared
Line emission time transmits infrared ray emission time, the third time of reception to controller；
4th infrared receiver end receives modulated infrared, the 4th time of reception of record, demodulates infrared ray and simultaneously records infrared
Line emission time transmits infrared ray emission time, the 4th time of reception to controller.
Although each infrared receiver end all demodulates and causes repetition transmission to controller transmission infrared ray emission time.But
It is that due to barrier etc., when actual location may have part infrared receiver end to fail to receive infrared ray, and then can not
To controller transmit infrared ray emission time, be arranged without exception all infrared receiver ends all transmit infrared ray emission time can be most
Big degree prevents the above problem.
As shown in figure 4, controller calculates the step of position of mobile transmitting terminal (S300) according to signal data, comprising:
S301, when being greater than or equal to 3 to the infrared receiver end quantity of controller transmission signal data, according to receiving
Signal data and preset rules calculate the position of mobile transmitting terminal；
S302, when to controller transmission signal data infrared receiver end quantity less than 3, show miscue.
