Embodiment
The key concept of automatic water-supply of the present invention and perspire rate measuring system is that water is pumped into this manikin from water pot, yet subject matter is how to measure the water yield that joins in this manikin and the water yield of scattering and disappearing from this manikin.Measuring the obvious method of moisture loss is to measure the weight of this manikin in real time with scale.Yet, because the general assembly (TW) of this manikin surpasses 75Kg, its moisture loss (or " perspire ") is lower than per hour 1Kg simultaneously, or about per minute 1～16g, like this, especially when this manikin carried out simulated humanbody walking action, the water level in this manikin fluctuateed up and down, like this, this electronic scales can not accurately be measured the weight change of 1～16g.At the problems referred to above, the present invention is a weight of only measuring a less container that is equipped with water in real time, and this less container is connected to this manikin by pipeline, to form siphonic effect, under the effect of siphon power, the water in this container can supply to this manikin in real time.
Particularly, see also Fig. 2, automatic water-supply of the present invention and perspire rate real-time measurement system comprise manikin 20, and this manikin 20 is similar with manikin of the prior art, all can finish circulation the flowing with the simulated humanbody inner blood of current in vivo; One container 25, this container is positioned on the quality meter 28, the water yield of about 6Kg is housed in this container, the enough manikins of this water yield " perspire " 10～15 hours, this container 25 is not mechanically connected to this manikin 20, but be connected with this manikin 20 by a flexible pipe 24, so just can guarantee that the water level in this manikin 20 is identical with water level in this container 25 by siphonage.Wherein in order between this container 25 and this manikin 20, to form siphonage, described container 25 should be arranged on a position that is higher than described manikin 20, thereby make the water in the described container 25 under the effect of siphon power, to be supplied to this manikin 20 automatically.In addition, by reading the weight of water in 28 these containers 25 that show in real time of this quality meter, can calculate the perspire rate of this manikin 20.Concrete computing method have detailed description hereinafter.
Control for convenience, this water system shown in Figure 2 also comprises three switches: valve 261, valve 262 and valve 263 are separately positioned on the diverse location place of this conduit 24.By opening also shut-off valve 263 of valve 261 and 262, the water in the container 25 can be fed in this manikin 20; By valve 261 cutting out and valve 262 and 263 being opened, water periodically can be pumped in this container 25 by a water inlet pipe 242, to fill with this container 25 when needed.When test perspire rate, valve 261 and valve 262 are opened and valve 263 is cut out, when in the flexible pipe 24 during fills with water, water in this container 25 will be under the effect of siphon power be communicated with water in this manikin 20, water supply start, when the water level in the container 25 was identical with water level L in this manikin 20, siphon power disappeared, and has finished automatic water-supply one time.Afterwards, after the moisture loss in this manikin 20 arrived to a certain degree, the water level L in the manikin can descend, thereby is lower than the water level in this container 25, at this moment can form siphonage again, beginning automatic water-supply again.
Preferably, this quality meter 28 is electronic scaless, so just can read the weight of water in this container easily.
Fig. 3 shows when this manikin 20 stand in the still air, the real-time reading of this electronic scales 28 and time relation curve.Fig. 4 shows when this manikin 20 moves in still air, the real-time reading of this electronic scales 28 and time relation curve.From Fig. 3 and Fig. 4 as can be seen, As time goes on, the reading substantial linear of this electronic scales 28 ground descends, and has shown that the water yield in the container 25 has little by little supplied to this manikin 20.In addition, the slope of Fig. 4 cathetus is greater than the slope of the straight line among Fig. 3, and the scatter ratio, scatter and disappear ratio (perspire rate) that has shown manikin moisture under walking states is greater than under static state perspire rate.
Fig. 5 shows this manikin 20 and stand under the static airborne state, and the reading of per 6 seconds these electronic scaless 28 changes and time relation figure.Fig. 6 shows this manikin 20 and moves in static air under the state of (walking), and per 6 seconds, the reading of this electronic scales 28 changed and the time relation curve.The difference of the curve shown in the curve shown in Fig. 5,6 and Fig. 3,4 is, the curve representation among Fig. 5,6 be the curve map of this electronic scales reading variable quantity in the time interval in 28 adjacent two 6 seconds.
If the water supply process of this automatic water supply system is uniform words, the curve among Fig. 5 and Fig. 6 should be a straight line.But this curve is that the sinusoidal curve that is similar to can draw from figure, and the water supply process of this automatic water supply system is uneven.The cyclic fluctuation of the reading of this electronic scales 28 is by the decision of the essence of siphonage.Need there be a small difference in finishing of siphonic effect between the water level of this container 25 and this manikin 20, so that water is transferred in the manikin 20.Suppose that they not there are differences on water level at first, along with the discharge of water in this manikin 20, the difference of water level becomes big gradually between this manikin 20 and this container 25.In case the potential energy that is formed by this water-head enough overcomes the resistance that water flows through conduit 24, water will flow to this manikin 20 from this container 25, and therefore, this electronic scales 28 has just write down the variation on this reading.Afterwards, when the water level after this manikin 20 increases is identical with water level after these container 25 reductions, current will stop.Afterwards, new circulation of beginning.Therefore giving on the process nature of this manikin 20 by these container 25 water supply is the cycle.But fluctuation is usually less than 1 gram (being at manikin shown in Figure 5 20 under the situation of standing state) or 1.5 grams (being at manikin shown in Figure 6 under the situation of walking states).
Because the fluctuation of the read period ground of this electronic scales 28 so when calculating the moisture loss rate, should filter out this fluctuation, perhaps should be used the data at the same period position of different time.In addition, what pay particular attention to is, the change of the reading of this electronic scales 28 is not equal to the windage of these manikin 20 moisture, linear dependence only just, this is because the water level of this manikin 20 is only added to concordantly with the water level that descended in this container 25, and does not replenish the water yield that all this manikins are scattered and disappeared.The moisture loss rate of this manikin 20 can be calculated by reading variation and the calibration factor (calibration coefficient) of following formula by this electronic scales 28:
Wherein, the moisture loss rate of this manikin of Q (or " perspire rate "), unit Grams Per Hour (g/h); Φ is a calibration factor,
Be poor (above-mentioned two readings should be positioned at same period position) of two readings of the electronic scales in a period of time interval, Δ t is twice time interval (unit second) between the reading.
In order to calibrate this system, water can be discharged from the one leg of this manikin 20, draw the curve that the water yield of discharge changes with respect to this electronic scales reading, this slope of a curve is exactly this calibration factor.This system need be before coming into operation and calibrates during the skin that at every turn more renews.
The beneficial effect of this automatic water supply system is, can safeguard the frequency of this manikin 20 and greatly simplifies the operation by reduction.Its function of measuring moisture loss in real time can detect the dynamic response of this manikin easily, has improved measuring accuracy simultaneously.
