附图说明 Brief Description

[0014] 图1是本测距鞋的修正系数计算原理图。 [0014] FIG. 1 is a correction coefficient to calculate this distance shoes schematic.

[0015] [0015]

·具体实施方式 · DETAILED DESCRIPTION

[0016] 下面结合附图对本发明进一步说明: [0016] the following with reference to the present invention is further illustrated:

该测距鞋包括左鞋、右鞋,所述左鞋内设有左无线收发器、计时模块、计算模块;所述右鞋内设有右无线收发器;所述左、右无线收发器开启时,左无线收发器向右无线收发器以等时间间隔发送离散信号,右无线收发器每接收到一个所述离散信号,就向左无线收发器返回一个反馈信号;所述计算模块首先依据计时模块计取的时间信息,确定左无线收发器从发出一个离散信号到收到一个对应的反馈信号所经历的时间。 The distance left shoe comprising shoe, right shoe, the left shoe left site radio transceiver module timing calculating module; the right of the right shoe equipped with a wireless transceiver; the left and right turn on a wireless transceiver When left to right wireless transceiver wireless transceiver to transmit discrete signals equal time intervals, the right wireless transceiver receiving one of the discrete signal, left the radio transceiver returns a feedback signal; first of all based on the timing of the calculation module Time to take into account the information module, the wireless transceiver is determined from the left to send a discrete signal to receive a feedback signal corresponding to the elapsed time.

[0017] 这里,各离散信号之间的时间间隔取lmiTlOms为宜,以保障每往返一次信号的过程中,两脚之间的距离基本不变;并且,计时模块按如下方式计取所述时间信息:将N次信号往返的时间进行累加,并将累加值输送给所述计算模块;其中,所述N次信号的时间间隔总和不大于IOms ;如此,计算模块确定的是信号往返一次的平均时间,这可以有效削弱信号往返过程中由于元件参数的不稳定引起的不确定性误差影响。 [0017] Here, the time interval between each discrete signal take lmiTlOms appropriate to protect every round trip signal in the process, the distance between the feet remain basically unchanged; and, the timing module as follows to take into account the time Information: The N times the signal round-trip time to accumulate, and the accumulated value delivered to the computing module; wherein the sum of the time the signal N times at intervals of not more than IOms; so, the calculation module determines the signal round trip average time, which can effectively weaken the uncertain errors affecting the signal and from the process due to the instability caused by the element parameters.

[0018] 接下来,所述计算模块根据离散信号往返一次的时间,计算信号往返过程中左无线收发器与右无线收发器的距离值,并记录该距离值;需要指出的是,在利用离散信号往返一次的时间计算所述距离值时,需要考虑电子元件的延时,因此,实际参与计算的时间应当是离散信号往返一次的时间减去离散信号往返一次过程中电子元件的总延时。 [0018] Next, the calculation module according to the round trip time discrete signal, the signal value calculated from the left and from the wireless transceiver during a wireless transceiver and right, and recording the distance values; It should be noted that, in the use of discrete When the signal round trip time calculating the distance values, you need to consider the delay of electronic components, therefore, the actual time involved in the calculation should be time minus the total round trip delay of the discrete signal discrete electronic components during the reciprocating movement of a signal.

[0019] 然后,所述计算模块再对记录的各距离值进行分析,其分析方法是:将各距离值通过插值法、最小二乘法等方式拟合成光滑曲线,求出该曲线的各个极大值;然后对各所述极大值进行累加,将累加值乘以一个修正系数,得到最终的路程值,输出至安装于左鞋上的显示屏。 [0019] Then, the computing module further distance values for each record is analyzed, the analysis is: Each distance value fitted smooth curve interpolation, least squares method, etc., to determine the poles of the curve Great value; then accumulate each of the maxima, the accumulated value is multiplied by a correction factor to obtain the final journey, the output to be installed in the display on the left shoe. 在求所述曲线的各个极大值时,采用导数法求解;其步骤为:首先求出该曲线的导函数,然后求出使导函数等于零的各个距离值,再分析该曲线在该距离值两侧的导数的正负,如在该距离值左侧,该曲线的导数为正,右侧为负,则该距离值为极大值;如在该距离值左侦牝该曲线的导数为负,右侧为正,则该距离值为极小值。 When seeking various maxima of the curve, using derivative method to solve; its steps: first find the derivatives of the curve, and then find the guide function of each distance value is equal to zero, and then analyze the curve value in the distance Derivatives of the positive and negative sides, as in the left side of the distance value, the derivative of the curve is positive, the right side is negative, then the value from the maximum value; derivative value as the distance of the left curve to detect female negative, on the right side is positive, then the value of the minimum distance.

[0020] 对于所述修正系数的设定依据,其计算原理如图1所示,不妨假设左、右无线收发器分别设置于左鞋、右鞋的脚心位置(若不设置于脚心位置,只要对应于左鞋、右鞋的相同位置,按照平移关系,并不影响分析结果);则,当右脚从虚线所示的脚印位置向上跨步后,所述计算模块通过离散信号的往返时间和信号速度,直接计算出的是跨步后前后两脚的脚心距a,而我们实际需要获知的是行进距离C,而a、c恰好与人体双脚平行自然站立时的脚心距b构成一个直角三角形,因此,c=a*修正系数=a*cos Θ,其中余弦角Θ =人体双脚平行自然站立时的脚心距b与自然跨步后前后两脚的脚心距a的比值的反正弦函数,即Θ =arcsin(b/a);参照图1,可知,对于绝大多数人,走路过程中,脚步交替的姿势基本相同(否则将被视为怪异),因此,无论身高如何,步长如何,图1中Θ角的变化却十分有限,实际测量过程中,一般情况下不同的人,对应的Θ角在24°〜30°之间,因此,对应的修正系数应当在cos24°〜cos30°之间,即0.87〜0.91之间,而如若使本测距鞋通用化,则修正系数可取0.89,这样,最后的得到的行程距离的误差率极值为(0.91-0.89) /0.87 ^ 2%,因此误差率在2%以内;如实际步行100m,测量的路程误差在±2m以内,完全可以接受。 [0020] For the correction coefficient is set in accordance with, the calculation shown in Figure 1, it may be assumed that the left and right radio transceivers are provided in the left shoes and right shoes, the soles of the feet position (if not provided in the soles of the feet position, as long as corresponding to the same position left shoes and right shoes, according to the translation relationship does not affect the results); then, when the right foot stepped upwardly from the position shown in broken line footprints, the computing module through discrete signal round trip time and signal speed is calculated directly before and after stepping away from the feet of the soles of the feet a, and we need to know the actual travel distance C, and a, c coincided with the soles of the feet parallel body when standing naturally form a right angle from the b triangle, therefore, c = a * correction coefficient = a * cos Θ, either before or after soles cosine angle Θ = human feet parallel natural standing distance b and feet soles of the feet after natural stride from a ratio of the inverse sine function that Θ = arcsin (b / a); Referring to Figure 1, we can see, for most people, walking the course, the pace of the alternate position is basically the same (or they will be considered weird), so that regardless of height, step How to change the angle Θ 1 is very limited, the actual measurement process, in general, different people, corresponding Θ angle between 24 ° ~30 °, therefore, the corresponding correction factor should cos24 ° ~cos30 between °, ie between 0.87~0.91, and should the shoe so that the distance universal, the correction coefficient 0.89 desirable, so that the travel distance error rate obtained last extremes of (0.91-0.89) /0.87 ^ 2 %, so the error rate is less than 2%; such as the actual walk 100m, distance measurement error within ± 2m, perfectly acceptable.

[0021] 本发明结合了人体步行时的脚步特征,通过曲线拟合方法获取两脚距离的每一次极大值数据,也就对应了每一次跨步动作后,两脚间的距离,乘上修正系数后,亦即对应每一次跨步动作后,人体行进的距离;通过本发明的技术方案,可以将目前的测距鞋中由各人步长差异所引起的较大的误差,转化为本发明中由各人对应的修正系数的差异而引起的较小的误差,不仅测量方便,并且明显提高了测量准确度。 [0021] The present invention is characterized by a combination of human walking pace when, to obtain maximum value of the data every two feet away from the curve fitting method, it corresponds to the action after every stride, the distance between the feet, take on After the correction factor, that correspond to every stride action, the distance traveled by the human body; through technical aspect of the present invention may be present in each big shoes ranging human error caused by the difference in steps, into small errors in the present invention, the difference correction coefficient corresponding to each man caused, not only to facilitate measurements and significantly improve the measurement accuracy.

[0022] 需要指出的是,实际应用过程中,左鞋与右鞋上的元件配置可以对换,并不影响使用效果,本申请中指明左鞋和右鞋只是为了表述清楚的需要,不应当构成对左鞋和右鞋的元件配置的限制。 [0022] It should be noted that the actual application process, left shoes and right shoes and components can be configured on the exchange, did not affect the results, the present application indicate left shoes and right shoes just to express a clear need, should not be constitute a restriction on the elements are arranged left shoes and right shoes are.

[0023] 以上所述仅为本发明的较佳方式,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。 [0023] The above-described preferred embodiment of the present invention and are not intended to limit the invention, any modifications within the spirit and principles of the present invention, made, equivalent replacement, or improvement should be included in the present invention within the scope of protection.
