The radar module includes radar chip (not shown), and the radar chip can issue radar wave, and can be with
Reflected radar wave is received, received radar wave can also be handled, to calculate the position of launch point, from
And coordinate can be converted thereof into convenient for identification.The radar module can be fixed on display module by bracket or mounting plate
On, facilitate and carries out touch-control identification.
The host 12 can be server, can also for processor having data processing function etc., the radar with
The host connection, can use wired connection, can also be using being wirelessly connected, and the radar can be by its received data
Or the data after its preliminary treatment are transmitted in host 12, are handled by host 12 is further to data.The host can
Its received data to be converted into the coordinate of touch point by calculating, display module 13 is allowed to do in interactive process correctly aobvious
Show feedback.
The display module 13 is connect with the host 12, and the host 12 can use it treated touch point coordinate
Data allow display module 13 to do correctly display feedback in interactive process, and the display module 13 can be display screen, projection
Instrument etc. shows equipment, the signal that the display module 13 can be transmitted with host, so that display module 13 does correctly display feedback.
The radar module 11, host 12 and display module 13 with power supply electric connection (not shown), provide electric energy for it, make it can
To operate normally.The radar module 11 is set to the periphery of the display module, touches on display module 13 to obtain in real time
Control the position data of point.
In other embodiments, the present invention can be used for projector for the radar module 11 of display control, such as Fig. 2 institute
Show comprising radar module 11, the host 12 being connect with radar module 11, the projector 23 being connect with host 12.
As shown in Fig. 2, the radar and the structure of host and its connection type are identical with first embodiment, therefore herein not
It repeats again.The projector 23 connect with the host 12, and the host 12 can be by the number of coordinates of its calculated touch point
It is fed back according to allowing projector 23 to do correctly display.The host signal received can be projected in perspective plane by the projector 23
On.The projector is the prior art, and structure is similar to the display module 13 in first embodiment, therefore details are not described herein.
In other embodiments, the present invention can also be used for other display equipment, structure and connection type with it is above-mentioned
Structure is identical, therefore details are not described herein, so that touch-control may be implemented without the display equipment of touch function originally
Operation, functional diversities are easy-to-use.
As shown in Figures 3 to 6, the present invention is used to show interactive radar module and its display exchange method, the radar
Module 11 is the present invention for showing control when radar is arranged one according to using the quantity of radar to be segmented into various embodiments
Radar is placed on the week of display module when in use by the first embodiment of the display control method of the radar system of system first
Side, so as to the position of the touch point in real-time detection to display module, as shown in figure 3, it can be placed on position 1, position
Set 2 or position 3 comprising following steps:
Step 1: radar module itself pre-determined bit, as shown in figure 4, firstly, using finger, pen or other contact element according to
The secondary edge for clicking display module B, such as the position 1-9 in Fig. 4, at this time the distance S of radar A real-time detection position 1-9 and
Angle Q value, as shown in Figure 5；
Step 2: induction ranging is accurately counted according to the distance S of detections of radar and angle Q value by trigonometric function algorithm
1,3,7,9 position coordinates are calculated, to identify the area size of display module B；
Step 3: calculating positioning, clicks any position on display module B using hand, pen or other contact element, such as schemes
Shown in 6；, distance S and the Q value of detections of radar to touch point, and be transmitted to host after carrying out primary Calculation to it or directly pass
Transport to host；
Step 4: display interaction, host carry out processing to received data and carry out pair with the coordinate data in step 2
It is converted into position coordinate data by calculating than after, is then transmit to display control module, the display control module control is aobvious
Show that module is shown in corresponding position.In step 1, also other are a variety of other than 9 point locations for localization method, such as 4 points fixed
Position, 6 point locations etc..
It is as follows to the Coordinate calculation method of operating point in the above process: as shown in figure 5, radar can detecte to position 1 with
The distance value S1 and S2 of position 7, at the same can detecte position 1 and position 7 respectively with the angle Q1 and Q2 of vertical direction, it is assumed that with
Position 1 is coordinate origin, i.e., coordinate is (0,0), and the coordinate of position 7 is (0 ,-S1cosQ1+S2cosQ2) at this time, such as Fig. 6 institute
Show, the coordinate of position C is (ScsinQc-S2cosQ2 ,-S1cosQ1+SccosQc), and the coordinate of other points, which calculates, refers to above-mentioned meter
Calculation method belongs to the prior art, therefore details are not described herein.In other embodiments, angle Q, which can also be designed, is in and horizontal plane
Between angle.
When radar setting is multiple, the touch point on display module can also accurately be positioned, the radar
It can be set three, four or six etc., it is even more.
More accurate to the detection data of touch point when radar quantity is more, the display position of acquisition is also more accurate.
