Detailed description of the invention: this utility model is described further below in conjunction with accompanying drawing:
External structure of the present utility model as shown in Figure 1.In appearance, this utility model has eight pressure detecting resistance to be arranged in major muscles position and anatomical features district when people walk, and arrangement eliminates the accuracy that data redundancy in turn ensure that pressure information like this.
Wearable plantar pressure checkout equipment described by this utility model as shown in Figure 3.This equipment comprises pressure sensor block 1, central processing control module 2, wireless communication module 3, host computer 4, gyroscope 5, accelerometer 6, signal prompt module 7, pressure sensor block, gyroscope 5 was communicated with connecting line with accelerometer 6 and was connected with central processing control module, this pressure sensor block is made up of eight pressure inductors and is positioned at the position that shoe pad side contacts with foot, be connected with central processing control module by connecting line, central processing control module can data by oneself, also can be communicated with host computer by wireless transmission, host computer carries out accurate data and calculates.Signal prompt module is made up of a LED display lamp and a buzzer.
The hardware configuration of wearable plantar pressure checkout equipment described by this utility model as shown in Figure 4.The force sensing resistance matrix of pressure sensor block, gyroscope, accelerometer, supply module are connected to central processing control module, central processing control module carries out data transmission by wireless transport module and host computer, host computer carries out computational analysis to data, signal prompt module shows signal.Central processing module process is from the plantar nervous arch information of force sensing resistance, gyroscope, accelerometer and angular pose information, then judge whether to meet in the parameter area that set, when using host computer by host computer curve plotting, reading data when not using host computer by central processing control module memory module, judging the movement tendency of user; Supply module is responsible for powering to whole circuit.
Implementation method of the present utility model is as follows:
(1) when sole contacts with the pressure sensor block on shoe pad, the force sensing resistance value R comprised in pressure sensor block can change, according to the specific non-linear relation of different existence of resistance material between R and f with the force value f applied thereon.Pressure sensor block is connected with central processing control module, and to monitor the pressure change produced between sole and shoe pad, central processing control module reads the magnitude of voltage V at each force sensing resistance two ends in modular pressure
o, and the value of force sensing resistance R is calculated by formula 1:
Wherein r is the divider resistance of connecting with force sensing resistance.When force sensing resistance there being pressure change, central processing module can return the numerical value between 0 to N in real time, wherein, and the value of N (N=2 relevant to the figure place n of processor
n-1), V
ifor the maximum of the voltage that central processing module can detect, therefore the magnitude of voltage that detects of pressure sensor block and its resistance present following relation:
People are when lift lower limb, walk etc. presents different attitude, the dynamics that foot steps down in pressure sensor block is different, the pressure information that force sensing resistance collects changes to some extent along with the motion of people foot, to be arranged the pressure distribution value formed on pressure sensor block by multiple force sensing resistance by gathering, just can obtain plantar nervous arch information.
(2) gyroscope and accelerometer is utilized to work in coordination, accelerometer is measured precisely in the long period, and have within a short period of time error to exist due to signal noise, gyroscope is more accurate within a short period of time, but the error then having drift in the long period and produce, therefore both combine can angular velocity θ on x, y, z axle when at time point and all Measurement accuracy people walk in the time period

(3) utilize central processing control module pressure information, acceleration information and angular velocity information that the multichannel force sensing resistance, accelerometer and the gyroscope that collect transmit to be carried out amplifying, denoising, filtering, level and smooth, decoupling process, then by wireless communication module, data message is sent to upper computer end;
(4) host computer arranges data message and analyzes, and on screen, depict surge pressure, calculating pressure and time integral, draws pressure distribution image, calculates by the accekeration in x-axis, y-axis and z-axis the attitude that foot may present.Because everyone walking posture is different, therefore before attitude prediction, first to set up individual and normally to walk knowledge base, and be recorded in host computer.In follow-up use procedure, the current Information and knowledge library information collected is compared and analyzes, judge whether the attitude of user coincide with normal attitude before;
(5) if when using host computer inconvenient out of doors, can by the data interval [α after the simplification in data base

2] in, then show that the attitude in present attitude and personal knowledge base has notable difference;
(6) no matter be carry out date processing by central processing control module or host computer, the movement tendency of capital to user makes a decision, people to fall down or other may potential dangers time, need to make surrounding population or user oneself note front road conditions by piping of buzzer, in addition, when the beginning work of format equipment, the signal that light emitting diode reminds user to start working by showing different colors, even if user has done unconventional action, host computer is caused to judge inaccurate, user also can know this equipment working state by signal prompt module.
Practical application of the present utility model is exemplified below:
This utility model provides a kind of Wearable plantar pressure checkout equipment.This plantar pressure checkout equipment can detect in real time and analyze plantar nervous arch situation, when not using during this equipment, without the need to taking off this equipment, can not affect normal walking, and when wanting to use this equipment, directly opening switch and namely can obtain plantar nervous arch information in real time.
Refer to Fig. 2, arrange in the position in the muscle that when arrangement of the force sensing resistance of pressure sensor block 1 is walked according to people, vola is used and anatomical features district thereof, instead of be used in the arrangement that whole sole fills it up with resistance, avoid data redundancy, decrease amount of calculation, speed up processing, and accurately can calculate plantar nervous arch.
Refer to Fig. 3, people's sole of walking presents different angles and state from the shoe pad of force sensing resistance, these different states quick electrical resistance collection of exerting all one's strength is different to pressure information, the data that the angle on shoe pad and ground is read by gyroscope are calculated, acceleration in all directions is obtained by accelerometer, by the difference of integrated information, center-control processing module judges which kind of attitude people are now in.
Refer to Fig. 4, central processing control module is communicated with host computer by wireless communication module, by data Real-Time Monitoring prediction attitude trend on host computer.
