Fig. 1 is a kind of external structure schematic diagram of intelligent height ruler shown according to an exemplary embodiment.Fig. 2 is basis The structural schematic diagram of tape measure ontology in a kind of intelligent height ruler shown in one exemplary embodiment.As depicted in figs. 1 and 2, this Shen Please intelligent height ruler include shell 10 and the tape measure ontology 1 and circuit board 2 that are arranged in shell 10.

In a specific embodiment, the capitiform of round, round rectangle or cartoon animals can be set into shell 10.Example Such as, there are two ear structures for setting on a circular housing 10.The head of cartoon Little Bear, frog or panda etc. is set on circular housing 10 Portion's image.The shell 10 of cartoon animals capitiform can enhance the interest of intelligent height ruler.

Tape measure ontology 1 includes Flexible rule case 11 and the ruler spring (not shown) being arranged in Flexible rule case 11,12 and of tape First spool 13.Tape measure ontology 1 uses structure identical with tape measure in the prior art, and this will not be repeated here.In ruler spring and first Under the action of spool 13, tape 12 can be pulled out or be retracted in Flexible rule case 11 from Flexible rule case 11.

Tape 12 is made of flexible material, is rollable property tape 12.Light shield layer 121 is arranged at intervals in tape 12. Specifically, light shield layer 121 uses blackstreak, uses white stripes between adjacent light shield layer 121.Black and white is set in tape 12 Alternate striped, wherein blackstreak and the width of white stripes are equal.

As shown in figure 3, being provided with MCU21 (Micro Controller Unit, micro-control unit), at least on circuit board 2 Two optoelectronic switches 22, display device 23 and power supply 24.Optoelectronic switch 22 is connect with MCU21.Display device 23 includes that display is driven Dynamic circuit and display screen.Display screen is connect by display driver circuit with MCU21, for showing the calculated measured of MCU21 Height data.Power supply 24 provides operating voltage for MCU21.Specifically, it is provided with display window 111 on shell 10, display screen is set It sets in display window 111.Specifically, display screen uses liquid crystal display or LED dot matrix screen etc..

In one embodiment, as shown in figure 4, optoelectronic switch 22 uses correlation optoelectronic switch.Two correlation photoelectricity Switch is arranged at tape exit, and is arranged along the draw direction of tape 12.It transmitter in correlation optoelectronic switch and connects Receive the two sides that device is oppositely arranged on tape outlet.Tape 12 is from the seam between the transmitter and receiver in correlation optoelectronic switch It is passed through in gap.When tape 12 is by each correlation optoelectronic switch, spaced light shield layer can block hair in tape 12 The light that emitter emits to its corresponding receiver, correlation optoelectronic switch generate switching signal.

In another embodiment, as shown in figure 5, optoelectronic switch 22 uses reflective photoelectric switch.Two reflecting lights The tape exit of Flexible rule case 11 is arranged in electric switch, and the same side of tape outlet is arranged in along the draw direction of tape 12. When tape 12 is passed through from reflective photoelectric switch side, spaced light shield layer can block reflecting light to establish by cable in tape 12 The light that the transmitter in the Central Shanxi Plain emits to receiver, reflective photoelectric switch generate switching signal.

When the application intelligence height ruler uses two optoelectronic switches 22, the every pulling pre-determined distance of tape 12 just has one The switching signal of optoelectronic switch 22 changes.I.e. optoelectronic switch 22 is in response to the light shield layer in tape 12.Wherein, pre-determined distance Width depending on black and white striped in tape 12.

The switching signal of two optoelectronic switches 22 is indicated using two Gray codes.When the movement of tape 12, two optoelectronic switches When transmitter in 22 is blocked to the light that its corresponding receiver emits, the output signals of two optoelectronic switches 22 can be with It is defined as 00, or is defined as 11 with may be reversed.

Two optoelectronic switches 22 are 00 in the output signal of initial position, when tape 12 is to when pulling outside Flexible rule case 11, The output signal of optoelectronic switch 22 are as follows: 00 → 10 → 11 → 01 → 00......, i.e., the signal of one group circulation change；When tape 12 When to 11 internal recovering of Flexible rule case, the output signal of optoelectronic switch 22 are as follows: 00 → 01 → 11 → 10 → 00......, i.e., one group is followed The signal of ring variation.

Optoelectronic switch 22 sends a signal to MCU21, and MCU21 carries out the change frequency of the output signal of optoelectronic switch 22 Count and be converted into the height data of measured.The height data result obtained using the application intelligence height ruler measurement is accurate.

MCU21 can determine the moving direction of tape 12 according to the variation order of the output signal of optoelectronic switch 22.Specifically For, when the output signal of optoelectronic switch 22 becomes 01 from 11, then determine tape 12 to pulling outside Flexible rule case 11；Work as photoelectricity When the output signal of switch 22 becomes 10 from 11, then determine tape 12 to 11 internal recovering of Flexible rule case.MCU21 is calculated tested The height data of person is shown by display screen, thus convenient for users to reading the height data that measurement obtains.

In other embodiments, the quantity of optoelectronic switch 22 can be greater than 2, and one optoelectronic switch 22 of every increase measures Resolution ratio just double.In addition, the interval between the adjacent light shield layer being arranged in tape 12 is also adjustable, interval is got over Small, the resolution ratio of measurement is higher, however tape 12 pulls the upper limit of speed also lower.

In a specific embodiment, as shown in Fig. 2, being additionally provided with locking device 14, locking device in tape measure ontology 1 When 14 locking, the not stretchy of tape 12；When locking device 14 unclamps, tape 12 can be pulled freely.

Specifically, locking device 14 includes the second spool 141, spring and button 142.Flexible rule case 11 include first shell and Second shell is provided with positioning column at the center of first shell inner surface, and the first spool 13 is set on positioning column.The coiling of ruler spring In space between the bottom surface of the first spool 13 and the inner surface of first shell, the starting point of ruler spring is fastened in positioning column. Tape 12 is wound around on the excircle of the first spool 13.One end of tape 12 is fixed on the column of 13 top surface of the first spool, ruler The other end with 12 can be pulled out from the outlet of the tape of Flexible rule case 11.Spring is arranged in positioning column.Second spool 141 is arranged On positioning column, and matching is arranged in the groove of 13 top surface of the first spool.Button 142 is fastened on positioning column.Second shell Center at offer through-hole, when second shell is fastened on the first shell, 142 top of button is protruded from except second shell.
