Abstract
The utility model relates to an ultrasonic diameter gauge. At present, the diameter of a tree can not be measured by an instrument without being contacted; the prior method is that the circumference of the tree is measured with a ruler and then the diameter is figured out, which wastes time and energy; and the prior ultrasonic module can only be used for measuring plane objects. The ultrasonic diameter gauge comprises a diameter gauge casing (1); a ranging circuit including an 8675 chip is mounted in the diameter gauge casing; the ranging circuit comprises a transmitting circuit provided with an NE555 astable multivibrator module and a receiving circuit; and the circuits are respectively connected with a transmitting probe (2), a receiving probe (3) and two laser pointers (4), wherein, the transmitting probe (2), the receiving probe (3) and the laser pointers (4) are arranged outside the diameter gauge. The ultrasonic diameter gauge can be used for measuring the diameters of trees.
Description
Technical field:
The utility model relates to a kind of instrument that utilizes the diameter of ultrasonic measurement tree.
Background technology:
Domestic also do not have a kind of can the contact to set the instrument that just can measure its diameter now.Existing big multi-method all is to measure its girth with chi, is calculating diameter then, does not only time-consuming but also require great effort the object of an existing ultrasonic wave module measurement plane like this.
Summary of the invention:
The purpose of this utility model provides a kind of ultrasound wave caliper that adopts hyperacoustic principle to measure the diameter of tree under the situation that does not contact trunk.
Above-mentioned purpose realizes by following technical scheme:
The ultrasound wave caliper, its composition comprises: the caliper housing, described caliper enclosure interior is equipped with the range-measuring circuit that comprises 8675 chips, comprise in the described range-measuring circuit and have radiating circuit and the receiving circuit that NE555 does not have steady multivibrator module, described circuit connects the transmitting probe and the receiving transducer of caliper outside respectively, and outside two laser pens of described caliper.
Described ultrasound wave caliper, the radiating circuit that described NE555 does not have steady multivibrator module comprises the oscillation frequency conciliation circuit that is made of the variable resistor W, resistance R and the capacitor C that are connected on the NE555, with comprise one group of amplifier on the output circuit that described NE555 is connected, described NE555 connects one-chip computer, and described two laser pens become 60 degree.
The beneficial effects of the utility model:
1. the utility model adopts be measurement environment in the open air.Temperature exists--and 40 spend between 35 degree and can work.
2. simple structure of the present utility model, can import, can show, can store and be input in the computing machine, battery working time be long.
3. during the described caliper course of work, ultrasonic distance measuring module in the ultrasound wave caliper adopts two probe modes, one is used for doing transmitter, another is used for doing receiver, ultrasonic transmitter is to some direction emission ultrasound waves, in x time, pick up counting, ultrasound wave is propagated in air, running into barrier in the way just returns, ultrasonic receiver receives that reflection wave just stops timing immediately, and the aerial velocity of propagation of ultrasound wave is 340m/s, according to the time t of timer record, just can calculate the distance (d) of launching site, that is: d=340t/2 apart from barrier.

Embodiment:
Embodiment 1:
The ultrasound wave caliper, its composition comprises: caliper housing 1, described caliper enclosure interior is equipped with and comprises NE555 and do not have steady multivibrator control module, described no steady multivibrator control module connects the transmitting probe 4 and the receiving transducer 2 of caliper outside, and two laser pens 3 are equipped with in described caliper outside.
The radiating circuit that described NE555 does not have steady multivibrator module comprises the oscillation frequency conciliation circuit that is made of the variable resistor W, resistance R and the capacitor C that are connected on the NE555, with comprise one group of amplifying device on the output circuit that described NE555 is connected, see shown in the accompanying drawing that the oscillator signal of output promotes ultrasonic transducer S1 sounding by the amplification of CD4049.The 4th pin Enable Pin of NE555 can be by Single-chip Controlling, and this pin is a high level when needs emission ultrasonic signal.The feeble signal that ultrasonic transducer S1 receives is amplified through being ac-coupled to IC1, and its enlargement factor is: A1=-R6/R4=-50; Amplifying signal is passing through another amplifier that is ac-coupled to IC1, and its enlargement factor is: A2=-R9/R7=-20; Full gain is: A=A1*A2=1000.Again by comparer LM311 shaping, output mark Transistor-Transistor Logic level signal is to be received by single-chip microcomputer through amplifying signal.Described two laser pens become 60 degree.
Described ultrasound wave caliper, described NE555 does not have steady multivibrator module and connects the 6V battery with electric wire, described laser pen connects the 3V battery with electric wire, and described two laser pens become 60 degree, and described laser pen is the position when being used for locating ultrasonic wave module and measuring.
Described laser pen sends two bundle laser and becomes 60 degree angles to switch on the tree described caliper position: the light that ultrasound wave sends is d to the distance of trunk; The radius of tree is r, according to geometrical principle sin30 °=R/R+d, can obtain radius R=d of tree, and diameter is 2d.
The reason that measured value is proofreaied and correct following two aspects can cause measured value ultrasonic distance measuring module less than normal to tree apart from the actual distance, delta d that must add range finder module of d to the caliper summit.May not have with tree not tangent fully by artificial vision reason laser pen.So last measured value R=d+ Δ d.
