Description
Technical field
The utility model belongs to positioning equipment field, particularly a kind of inertial positioning shoe-pad based on inertial sensor.
Background technology
Satellite navigation is current most widely used personnel positioning means, its technology maturation, wide coverage, in open area good positioning effect, but there is serious multipath and eclipse phenomena in it in city or indoor environment, positioning performance reduces even entirely ineffective greatly, and satellite navigation signals frequency and form openly, are easily disturbed in addition.Along with deepening continuously of satellite navigation application, its blind zone problem is also more outstanding, " mending blind " means that the autonomous location technology of the personnel based on inertial sensor is located as satellite navigation, and its importance highlights day by day.
Personnel independently locate the location referred to based on inertial sensor, and it measures the kinematic parameter of people only by the mini inertial sensor that human body is self-contained, thus extrapolates the relative position of personnel, obtains relative positioning result, thus reaches the object of location.Personnel independently locate not to be needed to install the equipment such as communication base station in advance, does not rely on outside equipment and environment, can provide relatively accurate positioning result in any environment, have reliable, real-time, portable advantage.
Adopt the personnel positioning apparatus of inertia measurement to need to be connected with human body, if take to be placed on pocket or hang is all difficult to accurately extract human body sport parameter, cause location inaccurate.At present, major part adopts the personnel positioning apparatus of inertia measurement to be all mounted on people's pin, and be connected with people's pin, positioning precision is higher.
The mode adopting the personnel positioning apparatus of inertia measurement and people's pin to be connected has following three kinds:
1. personnel positioning apparatus is closely wrapped in foot by having certain flexible bandage.
2. on footwear, a base or fixed mechanism are installed, during use, personnel positioning apparatus are installed on base or fixed mechanism.
3. personnel positioning apparatus is installed on heel place in sole.
The shortcoming of mode 1 and 2 is that user needs to take a long time at every turn and carries out binding and be wound around or install, and wastes time and energy; In strenuous exercise or when clashing into foreign object, there is the risk being shifted and even coming off in sensor, thus the precision of impact measurement and the reliability of work; Form the projection of profile in foot, and weight may cause the distortion of action of executing the task, and affects comfort level and the flexibility ratio of user; Sensor is directly exposed to external environment condition, proposes very high request, improve the difficulty of Design and manufacture to its fire prevention, waterproof and impact resistance.
The shortcoming of mode 3 is that dismounting and maintenance cost are high; Need to reequip shoes, the intensity of shoes may be destroyed.
Summary of the invention
Existing employing inertia measurement personnel positioning apparatus working costs effort, the precision of measurement and the reliability of work low, comfort level and the flexibility ratio of user are low, and the difficulty of Design and manufacture, cost is high.The purpose of this utility model is, for above-mentioned the deficiencies in the prior art, provides a kind of inertial positioning shoe-pad.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of inertial positioning shoe-pad, comprise insole body, be provided with power supply, inertial sensor, microprocessor, wireless interface chip and antenna in described insole body, described inertial sensor is connected with antenna by microprocessor, wireless interface chip successively, and described antenna is positioned at insole body edge.
The 3-axis acceleration measured and three axis angular rate information are delivered to microprocessor by inertial sensor, and microprocessor obtains relative position information through process, then is sent to exterior terminal by the wireless interface chip such as bluetooth or WIFI, antenna successively.
In order to improve the comfort level of user, power supply should be positioned at the arch of foot place of insole body.
Antenna is positioned at insole body edge, can reduce the impact that human body sends aerial signal.
Described insole body has two kinds of forms, and one is half cushion shoe-pad, and one is full cushion shoe-pad.Half cushion shoe-pad only pads the latter half at sole, and full cushion shoe-pad supports whole sole.
During use, directly shoe-pad is placed in footwear, convenient and swift; Can avoid suffering foreign object strike, reduce the risk of inertial sensor displacement, can not come off, improve the precision degree of location and the reliability of work; Because shoe-pad is built-in, both can not affect comfort level and the flexibility ratio of user, the fire prevention of shoe-pad itself, waterproof and impact resistance need not be considered during Design and manufacture, reduce cost of manufacture, reduce the impact of adverse circumstances for inertial sensor.
As a kind of preferred embodiment, described power supply, inertial sensor, microprocessor, wireless interface chip and entire physical are encapsulated in insole body, described power supply, inertial sensor, microprocessor, wireless interface chip and antenna are positioned in semicircular circuit board, and described semicircular circuit board is packaged in the heel place of described insole body.
As another kind of preferred embodiment, also comprise the first cavity in insole body and semicircle second cavity, described second cavity is positioned at the heel place of described insole body, described power supply is positioned at the first cavity, and described microprocessor, wireless interface chip, inertial sensor and antenna are positioned at the second cavity.
Second cavity can be convex shape cavity, described microprocessor, wireless interface chip and antenna are placed in the larger end of convex shape cavity, inertial sensor is placed in the comparatively small end of convex shape cavity, makes the shell wall around inertial sensor thicker, ensure the accuracy of sensor measurement data.
Further, be also provided with the environmental sensor for measuring three-axle magnetic field, temperature or air pressure in described insole body, described environmental sensor is connected with microprocessor.
Measure the direction that three-axle magnetic field can correct inertial sensor, measuring tempeature can correct the initial temperature partially of inertial sensor, and measuring air pressure can to highly carrying out subtest, thus make location more accurate.
As a kind of preferred embodiment, described antenna is pasted sheet type antenna.
As a kind of preferred embodiment, described power supply is dry cell, and position corresponding with dry cell on insole body has bottom.
As a kind of preferred embodiment, described power supply is rechargeable battery, is provided with the charging inlet be connected with described rechargeable battery in described insole body.
