Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, technical solutions of the utility model are described further.
As shown in Fig. 1, Fig. 2, a kind of rotational kinetic energy checkout gear of power consumption tester of skipping rope, comprises housing 7, described housing 7 comprises key part 1, Sensor section 2, singlechip control part 3, display section 6; By the preset body weight information of described key part 1 button, utilize described Sensor section 2 to gather useful signal, then processed by described singlechip control part 3 pairs of signals, show eventually through described display section 6 and detect data; Sensor section 2 gathers the information of jumping height, number and angular acceleration.Key part 1 comprises start and stop button, the preset button of body weight and reset key.Sensor section 2 adopts 3-axis acceleration sensor MMA7455 chip collection signal.Singlechip control part 3 adopts STC89C52 single-chip microcomputer to focus on all signals.Display section 6 adopts LCD12864 display screen to show.Housing 7 is tied up on arm 4 by the form of wrister.Angular acceleration is the angular acceleration of rope skipping 5 between the angular acceleration of arm 4 when beating and arm 4.
By the button of depresses button part 1 to single-chip microcomputer level signal, control to start and suspend, by depresses button to single-chip microcomputer level signal, the basis of acquiescence 60kg changes body weight information, the changing value △ h of height of C.G. when utilizing the characteristic collection of " Z axis is tested oneself " of 3-axis acceleration sensor MMA7455 chip self to beat, the size utilizing 3-axis acceleration sensor MMA7455 chip to measure the accekeration in three directions meets setting range and namely counts.
Sensor section as shown in Figure 3, MMA7455 is the micro-mechanical capacitance type three axis accelerometer of a compact, has very abundant function.It has low pass filter, signal condition, pulse detection and the temperature-compensating for Fast Moving Detection, the function such as to test oneself.0g is biased does not need exterior part with sensitivity, is all configuration of dispatching from the factory.User can calibrate the biased of 0g, and select by the g-Select range of specifying and 0g register, range selects 3 acceleration (2g/4g/8g) by specified command.By measured accekeration, algorithmically changed, obtained magnitude of angular velocity, thus the energy loss that rotary inertia causes can be measured.
Singlechip control part as shown in Figure 4, adopt AT89C52 single-chip microcomputer, AT89C52 single-chip microcomputer is a CMOS8 position single-chip microcomputer, its system programmable Flash, and memory has 8k, 3 16 bit timing device/counters.AT89C52 has 6 interrupt vectors: two interrupt (INT0 and INT1) outward, and 3 timer interruption (timer 0,1,2) and serial port interrupt.
Counting display section as shown in Figure 5, adopt LCD12864 liquid crystal display, this is a dot-matrix lcd module possessing 4/8 parallel-by-bits, its interface mode has 2 lines or 3 line serials etc. multiple, wherein it is also with one-level, secondary simplified form of Chinese Character character library, configure quite abundant, most of output display can be met.This module also has an advantage, is exactly low-voltage and low consumption, compared with the LCDs that other are of the same type, all more short and sweet in hardware and software, and price is also more economical.
Reset part as shown in Figure 6, the reset pulse applying one fixed width to RST pin realizes reset function.
Key part as shown in Figure 7, key circuit adopts independent keyboard, and clear in structure, circuit is simple.
Detailed process is: first by the preset body weight information of key part 1 button, then utilize Sensor section 2 to gather useful signal, useful signal comprises the acceleration on jumping height h and three direction, is processed all signals by singlechip control part 3.Single-chip microcomputer process comprises and judges on three directions, whether acceleration meets setting value, effectively beats, namely realize tally function if meet namely to calculate; Simultaneously according to the rope skipping 5 of three directional accelerations calculations and the angular velocity omega of arm 4, and then obtain arm 4 and rope skipping 5 swing losses; Also comprise the height h signal substitution physics formula E=mgh collected by sensor and calculate institute's work, namely consume energy measuring ability.Demonstrate the essential informations such as body weight, number, power consumption eventually through the display screen LCD12864 connecting single-chip microcomputer, reset function can also be realized by the reset pulse applying one fixed width to RST pin.
Concrete principle is: when people often jumps once, and the center of gravity of people will change once, and utilize physics formula E=mgh to calculate often to beat and once overcome gravity work, adding up, it is total to obtain total work E.Again according to the loss of the known energy overcome in gravity work and rope skipping process of law of conservation of energy.The calorie that (CAL)=4.184 joule (J) calculate consumption is blocked again by energy and caloric conversion formula 1.
