Embodiment

First kind of embodiment: Fig. 1 introduced the simplest a kind of altimeter.As seen from the figure: this instrument critical piece has two, and the one, flat bar 1, two, point tube 5.Flat bar 1 and point tube 5 one ends have bearing pin 4 hinges.Leveler 2 is arranged on the flat bar 1, and there is angle gauge 3 rear end.There is electric light source 8 point tube 5 the insides, can be generating lasers, also can be the battery and the luminotrons of emission oct beam.Linea angulata 6 is decided in indicating of the outside of point tube 5.In conjunction with Fig. 3 as seen: in order to measure the height of electric post, the people hands altimeter, flat bar 1 is set level, make the pearl of showing of leveler occupy meta, open electric light source, point tube 5 is upwards put certain angle, when light beam arrives the top of electric post 9, by measuring altimeter, can extrapolate the height of electric post 9 in conjunction with the tangent value of point tube pivot angle to the distance between the electric post 9.For convenience of calculation, preferably point tube 5 pivot angles are fixed on the fairly simple angle of functional value, as 45 degree, isosceles triangle, tangent value are 1, this moment, altimeter just equaled electric post height to the distance of electric post 9.Certainly, operation field is narrow sometimes, and this angle can't be operated, just can with 60 the degree, tangent value is 2, also relatively good calculation.Can certainly select other angles for use.

For when the point tube electric quantity of power supply is not enough, or endure when not having electric light source 8, point tube 5 is provided with gunsight 7, and the form of this gunsight 7 is a lot, for example through hole, foresight etc.Can aim to determine the angle of point tube 5 by the people.For easy to operate, can be as shown in Figure 4, the measurement starting point of electric post is improved one section, be equivalent to the height of eye, record data and add institute and stay and highly be electric post height.

Second kind of embodiment: on this altimeter, assembled microelectronic element, made it to have programmed control and automatic Presentation Function.Fig. 5 shows the block diagram of having lifted the simplest a kind of Single Chip Microcomputer (SCM) program control, comprises angular transducer, linear transducer, single-chip microcomputer program control module.The calculation procedure that to be provided with according to tan, just profound function and just profound theorem in the single-chip microcomputer program control module be mathematical model.Fig. 6 shows that the flat bar 1 of the altimeter of act is provided with display screen 10 and operating key 11.The angular transducer here can adopt the light signal sensing between point tube 5 and the angle gauge 3, also gear can be installed on bearing pin, by mechanical transducing signal, transmits the angle of point tube 5 rotations.Linear transducer 14 adopts manual supplied with digital signal.Single-chip microcomputer is received after the above-mentioned signal, calculates by definite program, obtains desired data, and shows through display screen 10, and the operator can obtain the elevation information of testee.Divide three kinds of situation explanation operating positions below:

Fig. 7 is as seen: measure a segment distance and measure near measured object.Earlier with manual button transmission range data, go up pendulum point tube 5 again, open the switch of electric light source 8 simultaneously, when light beam arrives the measured object upper end, the pivot angle degree is imported automatically on the point tube 5, single-chip microcomputer can calculate the length of opposite side according to the tan of this angle, i.e. the height of measured object, and on display screen 10, show.

Fig. 8 has introduced a kind of situation of more complicated.Measured object is difficult to approaching, can only measure in larger distance, and the distance between measurement point and the measured object is unknown.In this case, can provide the measured object height by the secondary measurement by method shown in Figure 8.For the first time measuring a α angle than far point, pushing ahead a segment distance B, the known and input of this distance records a β angle again.Single-chip microcomputer just can and equal 180 information of spending according to the right-angle triangle interior angle and learn the angle at each angle among the figure.By just profound theorem, promptly each limit of triangle and the relation that the ratio of the just profound value in diagonal angle equates obtain B/Sin θ=C/Sin γ, solve C, again with A=CSin α, draw the length data on A limit, are the height of the measured object of asking again, and show on display screen 10.In like manner, also can draw back again measuring, also can obtain desired value earlier at nearer point measurement than far point.

The situation that Fig. 9 introduces is more complicated, and measured object not only can not be approaching, and its root can not refer to by horizontal line again right.This situation can be divided into two sections with measured object by graphic technique, measures respectively, and two data input summation gets final product.This method can be spreaded to the remote measurement of width.

Certainly, in above-mentioned measurement, because of distance is far away, or the daylight abundance, the effect of electric light source is difficult to prove effective, and can adopt gunsight 7 to determine the angle of point tube 5 by range estimation.

Assembled flexible rule box 12 on the altimeter that the third embodiment: Figure 10 represents, there is tape strip 13 flexible rule box 12 the insides, flexible rule box 12 is provided with the wheeled linear transducer 14 that cooperates with tape strip 13, when pulling out tape strip 13, length signals can be imported automatically, the operation of range finding and manual input length data can be omitted.

The 4th kind of embodiment: but the tape measure of forming by the tape strip 13 of flexible rule box 12 and the inside pull assembled on the altimeter shown in Figure 11,12, its flat bar is a leveler 2 that flexibly connects with flexible rule box 12, leveler has roller for 2 times attached to above the tape strip 13, indication tape strip 13 maintenance levels.Establish roller type linear transducer 14 in the exit of tape strip 13, the distance that perception tape strip 13 is pulled out in addition.During use, as shown in figure 13, directly pull out tape strip 13, and the tip that point tube 5 is referred to measured object, single-chip microcomputer can obtain length, two information of angle simultaneously, can directly quote the height of measured object.
