Abstract
The utility model discloses an electronic belt capable of measuring the waistline. The belt comprises a belt head and a belt strap. A circuit board is arranged in the belt head. A small display screen and keys are installed in front of the belt head. A contact, a chip and a battery are arranged on the back of the belt head. The display screen, the keys, the chip and the battery are connected with the circuit board. The contact is located at the top end of a rigid plastic buckle. A wire is arranged from the contact and buried in the rigid plastic buckle, and extends to the circuit board; the wire is connected with an analog digital conversion pin on the chip through a guide circuit on the circuit board and used for measuring voltage. The portion, connected with the belt head, of the belt strap is provided with a point a. The portion 50 cm-90 cm away from the belt head is provided with a point b. The portion 5 cm-20 cm from the belt tail is provided with a point c. A thin wire is buried into the belt to the point b through the point a on the belt strap. The point b is provided with a resistance wire to the point c. The electronic belt has the advantage that accurate information of the waistline can be obtained conveniently when the belt is worn at ordinary times.
Description
Technical field
The utility model relates to a kind of belt, especially a kind of waistline electronic belt of surveying.
Background technology
At present, the known belt of market is all by leather belt head and belt configuration, only has simple wearing purposes.
Summary of the invention
The purpose of this utility model is existing belt to improve, so that electronic belt reaches, dresses and survey the complete new experience that waistline is integrated.
The technical solution of the utility model is: a kind of waistline electronic belt of surveying, this belt comprises leather belt head and belt strip, in leather belt head, be provided with circuit board, a small-sized display screen and button are installed in the front of leather belt head, the leather belt head back side is provided with contact, chip and battery, display screen, button, chip and battery are connected with circuit board, contact is positioned at rigid plastics button top, and from contact, establish a wire and be embedded in rigid plastics and extend to circuit board and be connected with the analog digital switched pins of chip by the guide passage circuit board in buckleing, for surveying voltage; Belt strip connects leather belt head place and is provided with a point, apart from leather belt head 50-90cm place, is b point, apart from belt tail 5-20cm place, is c point, and on belt strip, a thin wire of naming a person for a particular job is imbedded in belt to b point, and b point is established a resistance wire to c point.
The utility model has the advantage of: can, when dressing belt at ordinary times, obtain easily the accurate information of waistline.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is structure of leather belt head schematic diagram of the present utility model;
Fig. 3 is circuit theory diagrams of the present utility model.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
The utility model proposes a kind of method for designing of embedded system.Utilizing fully on the basis of existing belt manufacture craft, for belt embeds electronic system, providing better interactivity and convenience.Compare with conventional belt, this electronic belt has practicality, functional advantage.
Note: the long belt of the 120cm of take below describes as example
In Fig. 1, in mode intuitively, represented principle in kind.First from connecting a of the anode thin wire 4 of naming a person for a particular job, imbed belt until wire connects the b point of upper distance leather belt head 70cm, the resistance wire 3 that then starts to lay a long 40cm at b point is to the c point from belt tail 10cm place.Finally a small-sized LCD display 1 and button 2 are installed in the front at leather belt head, by wire, connect chip and the battery that settle leather belt head inner side respectively.
In picture 2, be the internal structure of leather belt head, contact 5 is positioned at rigid plastics button top, and from a section of contact, draws a wire and be embedded in rigid plastics buckles, and extends to the analog digital conversion pin of chip 6 for surveying voltage.7 positions for battery arrangement.Chip 6 and battery 7, display screen 1, button 2, chip 6 and battery 7 are connected with circuit board, and button 2 is equivalent to switch, controls open circuit plate, and measurement data is presented on display screen 1.
Fig. 3 is that cb section is the simplification of c to b section in figure mono-according to the summary schematic diagram drawing described in figure mono-, and 3 is resistance wire, and 5 is contact, and R1 is a divider resistance that resistance is suitable.As we know from the figure, anode passes through resistance R 1, then by a part for contact 5 UNICOM's resistance wires 3, finally connects GND, forms the structure of a series connection dividing potential drop.Contact may be fallen the diverse location of resistance wire 3 when the degree of tightness of belt system is different thus, thereby the magnitude of voltage that D is ordered will have different results, and at this moment D point voltage can be changed ADC by analog digital and records.
Example: suppose that cell voltage is VCC, divider resistance resistance is R1, and resistance wire total length resistance is R2, and it is Vr that ADC records voltage, and the resistance that contact is ordered to b is Rx, and length is X, and waistline is L, can demonstrate,prove so:
B point is apart from leather belt head a point 70cm, and the length bc section of resistance wire is 40cm.
:
VCC-Vr=(Vr*R1)/Rx
Rx/R2=X/40cm
L=70+X
To sum up: L=70+40* (Vr* R1)/(VCC-Vr) * R2
Electronic belt mainly consists of processor subsystem, ADC subsystem, display module and battery subsystem.Processor subsystem is mainly used in the core that system is controlled, and completes corresponding data sampling and processing and transmission; ADC subsystem responsible is converted to data signal by the analog signal of outside input, and as the key data source of display screen, battery subsystem provides the battery of multiple amount for each subsystem.
