Device is shown.
Such scheme is visible, pressure value is obtained using the pressure sensor being arranged on pedal body downside, according to pressure
The distribution situation of power determines direction and the degrees of offset of centre-of gravity shift, and transmits this data to the aobvious of periphery by bluetooth module
Shown on showing device, be adjusted accordingly and to human posture, the posture that human body is stood more is rationalized, penetrated to improve
Precision is hit to lay the first stone；Its is simple in construction, and cost is low, and stability is good.
Further, the number of the pressure sensor is 12, and 12 pressure sensors are uniform in a ring
Distribution.
Such scheme is visible, sets 12 pressure sensors, and is uniformly distributed, and it is real on 12 o'clock direction
Existing pressure measxurement, so cause centre-of gravity shift direction and degrees of offset measurement it is more accurate, improve of the present utility model
Reliability.
Yet further, two are provided with the upper surface of the pedal body and tramples region, area is trampled described in two
Domain is in footprint shape, and in the projection of the pedal body, 12 pressure sensors surround and trample region described in two.
Such scheme is visible, tramples the setting in region so that the position more specification that human body is stood, ensures center of gravity calibration
Reliability and stability.
Further, the CPU is single-chip microcomputer.As can be seen here, using single-chip microcomputer as CPU, its stable performance is expansible
Performance is good.
Brief description of the drawings
Fig. 1 is the easy structure schematic diagram of the pedal body；
Fig. 2 is the easy structure schematic diagram that the pressure sensor is distributed on the pedal body.
Embodiment
As depicted in figs. 1 and 2, the utility model includes pedal body 1, and the pedal body 1 is in the pedal body 1
CPU2 and bluetooth module 3 are provided with, the CPU2 uses single-chip microcomputer.It is provided with the downside of the pedal body 1 some
Pressure sensor 4, some pressure sensors 4 surround and are uniformly distributed.In the present embodiment, the number of the pressure sensor 4
Mesh is 12, and 12 pressure sensors 4 are uniformly distributed in a ring.The bluetooth module 3 and some pressure pass
Sensor 4 is connected with the CPU2, and the bluetooth module 3 sends the pressure value that the pressure sensor 4 obtains to periphery
Display device is shown.
Two are provided with the upper surface of the pedal body 1 and tramples region, it is in footprint shape that region is trampled described in two,
In the projection of the pedal body 1,12 pressure sensors 4 surround tramples region described in two.
When being calibrated using above-mentioned gravity center of human body's calibration system to gravity center of human body, its operating procedure is as follows：
A. using the center of the pedal body as standard position of centre of gravity, and the standard position of centre of gravity information is stored in
In data storage cell in the CPU2.
B. when ejaculator is stood on the pedal body 1,12 pressure sensors 4 detect pedal body
The pressure information of upper 12 positions.
C. the pressure sensor sends the pressure information of acquisition to the CPU2.
D. the CPU2 is overlapped calculating to these information, obtain current position of centre of gravity, then with being obtained in step a
Center for standard position compares, so as to obtain ejaculator centre-of gravity shift direction now and degrees of offset.This process it is specific
Step is as follows：
1. 12 pressure sensors are divided into six groups, hour direction is divided on time, 1 o'clock direction sensor and 7 points
The sensor in clock direction is divided into one group, 2 o'clock direction sensor and the sensor in 8 o'clock direction be divided into one group, 3 o'clock direction
Sensor and the sensor in 9 o'clock direction be divided into one group, 4 o'clock direction sensor and the sensor in 10 o'clock direction be divided into
One group, 5 o'clock direction sensor and the sensor in 11 o'clock direction be divided into one group, 6 o'clock direction sensor and 12 o'clock
The sensor in direction is divided into one group；
2. the CPU records the pressure value of two sensors in each group, hour number direction when taking in every group the first six
Pressure sensor value is m, and 7 points of sensor values to ten two directions are that n, wherein m and n are the pressure value measured；
3. when people with standard gestures station when on the pedal body, record each group of pressure differential ratio, the ratio
Calculation formula is (m-n)/X, and X takes the greater in m, n；
4. according to the characteristic of pedal body in itself, its meeting is laid particular stress on toward one side, takes one group of conduct that wherein ratio value is maximum
Standard centre-of gravity shift direction, its ratio value are degrees of offset.
E. the bluetooth module 3 shows the display device that the center of gravity measurement result obtained in step d is sent to periphery.
The utility model obtains pressure value using the pressure sensor being arranged on pedal body downside, according to pressure
Distribution situation determines direction and the degrees of offset of centre-of gravity shift, and the display dress of periphery is transmitted this data to by bluetooth module
Put and shown, is adjusted accordingly and to human posture, the posture that human body is stood more is rationalized, to improve shooting essence
Degree lays the first stone；Its is simple in construction, and cost is low, and stability is good.Applied to shooting field, the weight of ejaculator can be accurately obtained
Heart position, and center of gravity is adjusted according to shooting structure, so that follow-up shooting is more accurate.
The utility model can be applied to center of gravity measurement instrument field.
