Or：By mike speech detection, judge squel or carry out speech recognition, the jerk of control system or realization Acceleration or deceleration.

This utility model is examined using ripe technological means and simple manufacturing process using the many-side to movement human Survey, realize basic shatter-resistant function.

Scheme one, as shown in Fig. 2 popping one's head in using ultrasonic ranging, detects the position and angle of inclination of movement human upper body. Ultrasonic sensor can accurately calculate the distance between sensor and reverberation using the echo time.By continuous monitoring away from From variation, movement velocity can also be calculated.The distance that multiple position sensors are detected, can go out reflection sound wave with COMPREHENSIVE CALCULATING The angle of inclination of object.

Using range information, motor can be controlled and constantly adjust rotating speed, make movement human be maintained at running device Intermediate space.When movement human run very fast upper body convergence detector when, running machine motor is rotated just to be accelerated；Work as fortune The speed that moving body runs lowers when being gradually distance from detector, and machine can slow down.If the motion of people stops, motor Can as early as possible stop, realize automatically controlling for movement velocity.

Detection movement human upper body angle of inclination is excessive, when generation is seriously toppled over, can be out of service at once or reverse in short-term Operation is unbalance to correct motion.When being difficult to determine whether to topple over, running speed can be moderately reduced.

To avoid being interfered between multiple ultrasonic sensors, each sonotrode only sends fixed frequency f1, The short pulse of f2, f3.The sound wave pulse for receiving, it is which acoustical generator sends that can tell from frequency, and this contributes to keeping away Exempt from upper body Dip countion mistake.

Intelligence control system can be using 51 single-chip microcomputers or other 32 even 64 single-chip microcomputers.At present the calculating of single-chip microcomputer is fast Degree be enough to the resolution and ET, the calculating of position of real-time, quick realization difference ultrasonic signal frequency.Intelligence system needs Filter the harmful effect of the interference signals such as noise.Need to tell swing arm signal and movement human upper body compared between strong reflectance signal Difference, remove the deviation that swing arm signal causes to upper body Dip countion.

Multichannel short pulse ultrasonic signal can be generated by the CPU (single-chip microcomputer) of intelligence control system, through simple amplification After deliver to sonotrode and send.Ultrasonic frequency selects optional frequency in the range of 20kHz-1000kHz.Ultrasonic pulse width Degree selects arbitrary value in the range of 1 μ s-1ms.

Ultrasound wave receives the high-speed AD input that signal is directly transmitted to intelligence control system, or ultrasound wave reception signal is put Great achievement square-wave signal passes to the high-speed figure input port of intelligence control system.By intelligence control system interpretation ultrasonic signal Reception delay and frequency.

Motor control part is made up of high-power electronic device, possesses the ability for driving relatively high power motor.Driving power Ability is optional in the range of 10W-1kW.By intelligence control system according to result of calculation output pulse width modulated signal (PWM) control electricity Machine rotating speed.Also the voltage that can be exported by the DA outfans of intelligence control system or current signal controlled motor rotating speed.

Scheme two, such as Fig. 3, shown in Fig. 4, can be detected on the basis of scheme one with additional leg pedal signal.Using vibration Sensor signal can calculate the time difference of signal between multiple vibration detection probes, determine foothold on pedal with this Approximate location.If two neighboring foothold all uniformly falls in security interval, show that movement human is in plateau.If step Suddenly there is confusion in width or time interval of marking time, it is likely to there occurs that motion is unbalance, control system need to as early as possible slow down or shut down.

The calculating of vibration signal time difference is completed by the CPU (single-chip microcomputer) of intelligence control system.By vibration waveform signal by After AD port processings, calculated by mathematical algorithms such as related operations and obtained.

Scheme three, on the basis of scheme one, can add sound detection system.Filtering environmental background sound is strong with general Degree voice, once detect scream or larger sound, it is also possible to it is rapid to slow down or shut down.Playing auxiliary prevents serious traumatic injury work( Energy.According to computing system with better function, speech recognition, control function can be further realized.

This utility model can use 2-5 sensor instrument distance, calculate upper body angle of inclination.Because gravity center of human body is located at upper body, Measurement upper body state is most important.During measurement upper body signal, it is vulnerable to the impact of swing arm, needs exclusive PCR and kept away with multiple probes Exempt from erroneous judgement.

Head reflected signal can also be if necessary measured, but the people to different heights has larger difference.Need correspondence Adjustment height.Can also cross measure foot signal, if foot is located further forward than upper body, will not lean forward certainly and fall down.

This utility model can also measure the position that foot is stepped on pedal, contrast upper body position to judge whether center of gravity is located Between bipod.

First it is to slow down once noting abnormalities by judging stride and frequency, it is also possible to find the exception before falling.Such as Fruit finds severely subnormal (with squel), can stop at once, in order to avoid serious traumatic injury.
