The specific embodiment
The present invention will be described in detail below in conjunction with Fig. 1-3.
As shown in Figure 1, but the treadmill 1 of human perception of the present invention, have run with 11, horizontal bar 12, console 13, the controller 2 of treadmill, the ultrasonic receiving device 6 of treadmill support body and this support body.Shown in Fig. 3 was further, whole ultrasonic ripple R-T unit 6 comprised ultrasonic sensor 61, ultrasonic signal treatment circuit 63 and ultrasonic drive circuit 62.Ultrasonic sensor 61 receives inductor 612 by ultrasonic wave emission inductor 611 and ultrasonic wave and forms.In ultrasonic signal treatment circuit 63, amplifying circuit 631, shaping circuit 632 and filter circuit 633 are electrically connected successively.The amplifying circuit 631 of ultrasonic signal treatment circuit 63 is connected with the reception inductor 612 of ultrasonic sensor 61, the emission inductor 611 of ultrasonic sensor 61 is connected with ultrasonic drive circuit 62, and ultrasonic drive circuit 62 is connected with the controller 2 of treadmill.
For reacting the distance of human body on treadmill 1 more realistically, the ultrasonic receiving device 6 in the treadmill 1 can have left and right two groups, and the ultrasonic drive circuit 62 in every group of ultrasonic receiving device 6 is connected with the controller 2 of treadmill 1 respectively separately.Every group ultrasonic wave emission inductor 611 and ultrasonic wave receive on the console 13 that inductor 612 Guan County are installed on treadmill as shown in Figure 1 or on the horizontal bar 12 of treadmill support body, specifically be positioned at the both sides of the horizontal bar 12 of the both sides of front end of console 13 or treadmill support body, make ultrasonic sensor 61 roughly be in the height of human body waist, can measure the distance between the console 13 of human body and treadmill so exactly.Since ultrasonic receiving device 6 in the both sides of the front end of console 13 or the both sides of the horizontal bar 12 of treadmill support body respectively have one group, than having only one group of ultrasonic receiving device 6, can reduce the error of the distance measurement of human body and console 13.If have only one group of ultrasonic receiving device 6, ultrasonic sensor 61 generally is installed in the centre position of the horizontal bar 12 of the centre position of console 13 front ends of treadmill or treadmill support body.
As shown in Figure 1, if the control scheme of treadmill drive motors adopts variable frequency regulating speed control, correspondingly the drive motors of treadmill adopts phase asynchronous alternating current generator, and this threephase asynchronous machine 4 is connected on the treadmill special converter 3, and this frequency converter 3 is connected with the controller 2 of treadmill.
As shown in Figure 3, can be connected with ultrasonic ranging microprocessor 5 between the controller 2 of treadmill and ultrasonic drive circuit 62, controller 2 can be connected by RS232 asynchronous serial port communication modes with ultrasonic ranging microprocessor 5.This ultrasonic ranging microprocessor 5 can more effectively guarantee independence, continuity and the accuracy of ultrasonic transmission/reception signal work, obtains man-machine more accurately distance, realizes the control function of treadmill of the present invention better.
The ultrasonic exciting signal that is produced by ultrasonic ranging microprocessor 5 cushions through ultrasonic drive circuit 62 and amplifies, after through ultrasonic wave emission inductor 611, launch the ultrasonic wave of reasonable watt level by ultrasonic wave emission inductor 611.Drive circuit 62 can adopt different driving to amplify mode according to actual conditions, can be that the multichannel phase inverter pushes away and exempts to amplify, and can be that the MAX232 chip amplifies, and also can be that the special pulse transformer of design amplifies.Because the people is nearer apart from console 13 on treadmill 1 time, general preferred use multichannel phase inverter pushes away exempts to amplify.Ultrasonic wave emission inductor 611, ultrasonic wave receive inductor 612 and are responsible for launching the ultrasonic wave that ultrasonic wave and induction reflect.The 63 pairs of ultrasonic waves of ultrasonic signal treatment circuit receive that the signal that inductor 612 receives amplifies, shaping and filtering are handled, and make things convenient for controller accurately to obtain hyperacoustic transition time, and then obtain accurate distance.It is the operational amplifier chip of LM358 that amplifying circuit 631 adopts model; It is LM393 comparator chip that shaping circuit 632 adopts model; It is the LM567 phase-locked loop chip that filter circuit 633 adopts model, filters the noise of other frequency ranges.Ultrasonic ranging microprocessor 5 is opened counter in the field wave emission.In a single day ultrasonic ranging microprocessor 5 receives the ultrasonic signal that reflects and promptly stops counting, obtains hyperacoustic transition time t, can obtain distance value according to formula d=C*t/2, and wherein, C represents the aerial spread speed of ultrasonic wave.Pass to the controller 2 of treadmill by serial ports, the distance value that is recorded according to two groups of ultrasonic receiving devices by controller 2 carries out algorithm and converts, and obtains a man-machine accurately distance.
After treadmill 1 of the present invention starts, running is with 11 to remain static at first, the running that this moment, the body builder set foot on treadmill is with on 11, regularly produce pumping signal by ultrasonic ranging microprocessor 5, the ultrasonic wave emission inductor 611, the reception inductor 612 that are embedded in console 13 front ends or the treadmill support body hurdle 12 are started working, ultrasonic wave microprocessor 5 is read data that left and right ultrasonic distance measuring module measures and the controller 2 that passes to treadmill respectively, and controller 2 obtains the distance between the front end of human body vertical direction and console 13.The controller 2 of treadmill 1 can assign control command for treadmill special converter 3 according to distance value, allows treadmill 1 low rate start.In like manner, the body builder goes down to run and is with 11 in body-building end or the body-building process, and the speed of treadmill 1 can stop automatically, allows treadmill 1 have low rate start or nobody stops the Based Intelligent Control of speed.The body builder also can be in body-building running process selects people's speed intelligent-tracking physical training style on the human-computer interaction interface control panel, controller 2 can accurately measure human body at the particular location of running on 11 according to preceding method.Controller 2 is according to people's position judgment and control: if people's position near running with 11 centre to terminal, then treadmill motor phase asynchronous 4 slows down; If people's position hits console near running with 11 centre position to top for avoiding the body builder, treadmill threephase asynchronous machine 4 needs to quicken.Thus, realize that treadmill tracking body builder's speed is to reach the effect of intelligent-tracking.The speed of body builder's velocity no matter, the body builder all the time all can be near the centre of running on 11 position and need not to take care to drop out to run and be with 11 or hit console 13.
In body builder's running process, the controller 2 of treadmill 1 is judged by the distance of human body and console 13 whether the people has to drop out and is run with 11 or hit the danger of console 13.If have, 2 of controllers carry out of short duration deceleration or of short duration acceleration control, guarantee that body-building does not have to fall possibility of falling or hitting console, thereby the function of realization security monitoring are avoided falling and fallen.
Aforesaid treadmill speed control principle also can be applied in the treadmill lifting, to reach better result of use simultaneously.
