Detailed description of the invention
In order to keep the purpose of the present invention, technical scheme and beneficial effects clearer, the present invention provides following attached drawing and carries out
Explanation：
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Below in conjunction with attached drawing, a preferred embodiment of the present invention will be described in detail.
As shown in Figure 1, the present invention is a kind of electric assisted bicycle intelligence control system based on multi-parameter, including human body
Multi-physiological-parameter acquisition module, physical sensors module, signal pre-processing module, Complex Control Center, communication module and intelligence
Safety device；
Physiological signal collection module includes heart rate acquisition device, brain wave acquisition device, temperature collecting device and exercise intensity
Device；Physical sensors module mainly includes acceleration transducer, 3-axis acceleration sensor；Signal pre-processing module includes letter
Number amplification, filtering, amplify again and A/D conversion；Communication module mainly includes bluetooth and WIFI；Intelligent security guard module include report
Alarm device and dead-man's device.
The relationship of above-mentioned each component is as follows：
Human Body Physiology Multi-parameter acquisition module, physical sensors module, signal pre-processing module, communication module and intelligence peace
Anti- device is connected with Complex Control Center；
Heart rate acquisition device in human Body Physiology Multi-parameter acquisition module is mainly the reality for monitoring bicyclist in motion process
When heart rate (N) and body temperature (T), what brain wave acquisition device was surveyed is brain electric (E) and the respiratory rate (V) in motion process.Heart rate is
Heart rate monitor by being worn on wrist provides, and temperature is measured by wearable intelligent vest, and brain electricity and respiratory rate are by intelligently pacifying
The full helmet monitors to obtain.The heart rate of normal adults is generally at 60-80 beats/min, 36 DEG C -37.4 DEG C of armpit body temperature, natural shape
Normal person's respiratory rate is 16-20 beats/min under state." β " brain wave, the mankind are under a kind of common, daily waking state
Brain wave situation, frequency 12-50Hz.It can be respectively G0, G1 by power-assisted point 5 grades according to the above multi-physiological-parameter,
G2, G3, G4 qualitatively judge whether start force aid system under different conditions.Wherein G0, G1 do not need power-assisted, it is therefore an objective to allow and ride
Passerby carries out reasonable strength fitness campaign；G2, G3, G4 then need power-assisted, it is therefore an objective to the persistent movement under varying strength, to reach
Different body-building effects.With the increase for moving exercise intensity of riding, the above parameters can fluctuate, judge indirectly
The degree of fatigue of people's movement, and then an additional tractive force is provided to bicyclist.
Physical sensors module includes mainly including acceleration transducer, velocity sensor and cadence sensor.Add
Velocity sensor is 3-axis acceleration sensor, and is placed in the standpipe close to vehicle seat, with the change of gravity center of human body to
Judge whether to be in upward slope stage and real-time acceleration, in velocity sensor An Fang Yu Head pipe, for surveying bicycle advance
Speed.Normally the lie fallow average speed ridden of normal adults is 3-5m/s, since China's highway longitudinal slopes at different levels are generally in 3%-
10%, i.e., slope angle is between 1.72 ° -5.71 °.Can according to the carry out power-assisted classification for moving with uniform velocity quantitative under different slope angles, when
Encounter upward slope, speed when contrary wind, acceleration and cadence accordingly change, according to the tired of the bicyclist under different conditions
Labor degree, can be supplied to bicyclist's tractive force is：FIt helps=mgSin θ+υ mgCos θ-F0。
Communication module includes bluetooth and WIFI, is referred to as transmission medium connection Complex Control Center and other modules, transmitting-receiving
It enables, carries out real time communication.
Intelligent security guard module includes alarm and brake gear, when power supply module and electric motor system occur not enough power supply or
When circuit breaks down, it can show and give a warning in App；The effect of brake gear is when bicyclist drives moped
When there are excessive velocities, Complex Control Center can issue dangerous command to electric motor system, make its closing, guarantee speed in safety
In range.
By taking a healthy adult open air bicyclist as an example, to illustrate the wisdom classification of moped.It is each before not moving
Physiological parameter is as follows：
Heart rate：65 beats/min of body temperature：36.3℃
Brain wave frequency：12Hz respiratory rate：18 beats/min
Power-assisted classification under the different physiological parameters of table 1
5 grades of wisdom power-assisted point are respectively G0, G1, G2, G3, G4.The G0 known to table, G1 do not need power-assisted, purpose
It is that bicyclist is allowed to carry out reasonable strength fitness campaign；G2, G3, G4 then need power-assisted, the reason is that mentioning step by step with exercise intensity
The physical efficiency of height, bicyclist itself has been unable to meet needs, and system is needed to provide additional power.Under Exercises of different intensity, function
Energy purpose is different, therefore, can be by persistent movement of this hierarchical application under varying strength, to reach body-building effect.
In China's highway longitudinal slopes at different levels generally in 3%-10%, i.e., slope angle is between 1.72 ° -5.71 °.It can be according to different slopes
The size of speed carries out power-assisted classification under angle.Maintaining an ordinary bicycle movement probably to need size is the power of 15N, it is assumed that people
Gross mass with vehicle is 80kg, g=10m/s2, by the friction factor of resistance it is 0.02 in motion process, Regular Bicycle is ridden
Scanning frequency degree is 18-30 kilometers per hour, is roughly equal to 5m/s-8.3m/s.Then when different slope angles move with uniform velocity, moped is mentioned
Supplying bicyclist's tractive force is：FIt helps=mgSin θ+υ mgCos θ-F0, as a result as shown in the table
The size of power-assisted under 2 different gradient of table
Finally, it is stated that preferred embodiment above is only to illustrate the technical solution of invention rather than limits, although passing through
Above preferred embodiment is described in detail the present invention, however, those skilled in the art should understand that, can be in shape
Various changes are made in formula and to it in details, without departing from claims of the present invention limited range.
