Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
With reference to shown in Figure 1, a kind of irregular area self-operated measuring unit, comprise controller 4, described controller 4 is connected with LCD 1, temperature sensor 2, button inputting circuits 3, ultrasound wave transceiver circuit 5 and stepper motor driving circuit 7, described ultrasound wave transceiver circuit 5 is connected with ultrasonic sensor 6, and described stepper motor driving circuit 7 is connected with stepper motor 8.
Further, described controller 4 is the ATmega16A single-chip microcomputer.
Further, when measuring area, can calculate a subtriangular area according to known stepping angle and measurement mechanism loca to the distance on two limits on irregularly shaped object border, stepper motor 8 rotates a circle, and measures the area that all little triangle areas and accumulation are whole irregularly shaped object.
The principle of work of present embodiment is as follows:
As shown in Figure 2, ultrasonic sensor 6 is fixed on the liftable support, regulates support height and be convenient to find better irregularly shaped object edge reflection face, support is by stepper motor 8 driven rotary, and stepper motor 8 is by controller 4 controls.When measuring area, with measurement mechanism be positioned in the irregularly shaped object certain a bit, ultrasonic sensor 6 is measured this to the distance between the border, stepper motor 8 rotates a stepping angle (1.8 ° or 3.6 °) under the control of controller 4, measure the distance on this point and border again, according to recording two limits and definite stepping angle can calculate a subtriangular area, the rest may be inferred, and stepper motor 8 rotates a circle, and measures all little triangle areas and this is accumulated the area that is whole irregularly shaped object.LCD 1 is used for showing measures numerical value and working state of system, and temperature sensor 2 is used for measures ambient temperature to be used for revising ultrasonic propagation velocity, with further Hoisting System measuring accuracy.Button inputting circuits 3 is used for systematic parameter being set and certain man-machine interface being provided.
When system implemented, controller 4 was selected 8 AVR single chip computer AT megal6A of high-performance, low-power consumption.Low in energy consumption, the incomparable advantages of many other displays such as volume is little, in light weight, ultra-thin, radiationless, low flicker that LCD 1 (LCD) has select 2 * 16 character mode lcd display lcds 1602 as system's display device.Because the single bus interface mode of DSl8B20 uniqueness has remarkable advantages when multi-point temperature measurement, the I/O pin resource that takies MCU is few, fairly simple with the communication protocol of MCU, cost is lower, long transmission distance, so, select for use DSl8B20 as thermometric sensor.Ultrasonic sensor 6 requirements have transceiver, detect distance, and the region between the heart and the diaphragm district is less, the characteristics that transmission circuit is realized easily.When stepper motor 8 is selected, should satisfy control accurately, operate steadily, stepping angle is less, four characteristics such as driving mutually.
The mode that adopts parallel transmission that is connected of single-chip microcomputer and LCD display device, one group of I/O port (as the PA mouth) with the ATmegal6A single-chip microcomputer during connection is connected with 8 position datawires (D0-D7) of LCDl602, three I/O ports of ATmegal6A single-chip microcomputer (as PC5, PC6, PC7) select port (R/W), data/command selection port (RS) to be connected the external regulating circuit of LCDl602 bias voltage pin (VEE) with enable port (E), the read/write of LCDl602 respectively.Make up single-chip minimum system, to the LCD display power supply, write corresponding control program again and can realize that character shows.
Temperature sensor 2 is selected single bus interface device DS18B20, so itself and interface microcontroller are very simple, only an I/O port of ATmegal6A single-chip microcomputer is connected to unibus DQ and the external pull-up resistor of DS18B20, vdd terminal with DS18B20 is connected to positive source again, and the GND end ground connection of DS18B20 gets final product.Keyboard input circuit 3 is several buttons, as long as one of each button is terminated on I/O port of single-chip microcomputer, an other end ground connection gets final product.
Stepping motor 8 drives with pulse current.If whenever revolve to turn around and calculate with 200 excitation signals, each excitation signal 1.8 degree that advance then, its anglec of rotation is directly proportional with umber of pulse, and forward and backward can be controlled by pulse sequence.The excitation mode of stepping motor 8 can be divided into full step excitation and partly go on foot excitation, wherein goes on foot the branch that excitation has 1 phase excitation and 2 phase excitations again entirely, claims 1-2 phase excitation and partly go on foot excitation.Pulse signal of every output, 8 of stepping motors make a move.Therefore, constantly send pulse signal in regular turn, can rotate continuously by stepping motor 8.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
