Brief description of the drawings
Attached drawing described herein is used for providing further understanding the embodiment of the present invention, forms one of the application
Point, do not form the restriction to the embodiment of the present invention.In the accompanying drawings：
Fig. 1 is the system structure diagram；
Fig. 2 is the structure chart of real time monitoring apparatus.
Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to embodiment and attached drawing, to this
Invention is described in further detail, and exemplary embodiment of the invention and its explanation are only used for explaining the present invention, do not make
For limitation of the invention.
Embodiment
As shown in Figure 1, the present invention provides a kind of real-time interaction system based on self-adapting following treadmill, the system
Including real time monitoring apparatus, system control module, arrangements for speed regulation, input module, display device and wireless communication module.
By real time monitoring apparatus seizure runner leg speed, (technology uses the antenna of a determining deviation to the system, and measurement is solid
The movement locus for the beacon being scheduled on runner's shank, so as to calculate the speed and movement tendency of runner), be by inside
System bus sends the data to system control module, system control module control arrangements for speed regulation by treadmill adjustment of rotational speed to race
Step person is synchronous；Velocity information is sent to the processor of display device, display dress by simultaneity factor control module by system bus
The racing track landscape picture that the processor put stores in advance according to the playback of this speed；Simultaneity factor control module passes through wireless telecommunications mould
Block and network communication, obtain participating in the speed and current location information of other users of networking, while send the machine runner's
(current location information is according to runner's starting set-point and running instantaneous velocity and runs the time for speed and current location information
Integration calculates the distance of running, and although the racing track in virtual scene appears to be having for 3D curved, but runner is in program
Simply positioned on straight line with a numeral, this numeral is exactly the runner position being calculated, in other words virtual field
The switching of scape simply switches according to the distance of runner's race, without the presence of the other informations such as direction), obtained according to it
Obtain participating in the speed of other users of networking and current location information shows other positions run in friendly speed and virtual racetrack
Confidence ceases.Since treadmill is no longer run with setting speed, the physical efficiency discrimination of each participant causes participant and actual ratio
Match is almost consistent.
The real-time interaction system of the application, runner's operation input interface, some virtual ring provided into system are provided
Border program, runner can play or voice interface with the runner of other on network in virtual environment, display
(can also be the VR helmets or TV) be shown in selected virtual environment with the scene of runner's velocity variations and other
The animating image of runner, runner can exchange with other runner's real-time phonetics in whole interactive process, and can carry out
Running contest or other real-time interactives, the system considerably increase the property of participation and real-time, interactive of road-work.
Real time monitoring apparatus uses the antenna of a determining deviation (5-50cm etc.), and measurement is fixed on runner's shank
(antenna is located at the same side of treadmill side, and has distance phase at regular intervals, apart from treadmill side between two antennas
Deng；And must be fixedly arranged at according to design, beacon on shank, because system is that the leg speed of running is analyzed with the movement locus of shank
Information) movement locus of beacon, the speed and fortune of runner are then calculated using alternating electromagnetic field displacement amplitude analytic approach
Dynamic trend.As shown in Fig. 2, A1, A2 are antenna, C is processor of single chip computer, and E is that the signal being fixed on runner's shank occurs
Device.The specific calculating process of alternating electromagnetic field displacement amplitude analytic approach is as follows：
E launch some strength electromagnetic wave signal, with the movement of runner's shank, E with certain speed skim over A1 and
Near A2, A1 and A2 will be sent to C after the electromagnetic signal received amplification, and the signal is acquired C and height analysis, from
Among the trend of changes in amplitude, E can be calculated and skim over time immediately ahead of A1 and A2, specifically counted so that one is run the cycle as an example
Calculation process is as follows, and during E takes a step from back to front with shank, first close to A1, the signal that A1 is received becomes larger, and C is pressed
Signal amplitude is acquired and stored according to the time interval every 1ms (or shorter), the change of the amplitude curve is analyzed, works as E
When reaching A1 front vertical faces, according to field distribution rule, A1 receives most strong signal amplitude at this time, and following E continues toward reach
Dynamic, the amplitude that A1 is received is less and less, the time that C occurs according to maximum point at this time, marks the time t1 that E passes through A1, together
Sample reason, when E reaches A2, can measure arrival time t2, then the movement velocity v=t1-t2/d of shank (d A2, A1's
Interval), shank is still moved forward at this time, and measurement process is within a cycle of running, and is provided for motor
Velocity information before landing.Movement tendency is the change of the speed of the runner drawn based on the data record in measurement process
Change trend, acceleration magnitude, direction.
So as to calculate the movement velocity of runner leg, (calculating process is calculating human body in the time in units of ms
Physical location changes within 1CM, does not influence the response of motor), then C sends velocity information to system controller, in real time
The speed of treadmill and the speeds match of runner are adjusted, whole process is soared in runner's both legs and completed in process, runner
The velocity variations of imperceptible treadmill.
The present invention is measured using alternating electromagnetic field displacement amplitude analysis mode and associated monitoring devices, race is calculated in real time
The real time kinematics speed and movement tendency of step person, and in real time adjust treadmill motor speed, runner's double float when
In, calculating and adjust the real-time speed of treadmill so that runner produces the arbitrary illusion run on a runway,
Running experience is greatly improved, while it also avoid the knee joint injury that runner's forced synchronism velocity is brought.
Above-described embodiment, has carried out the purpose of the present invention, technical solution and beneficial effect further
Describe in detail, it should be understood that the foregoing is merely the embodiment of the present invention, be not intended to limit the present invention
Protection domain, within the spirit and principles of the invention, any modification, equivalent substitution, improvement and etc. done, should all include
Within protection scope of the present invention.
