Description
Technical field
The present invention relates to box, the dynamics speed detection system of tae kwon do, free combat, wushu training, belong to the technical field that electronic technology, computer technology combine.
Background technology
The method of the measurement impact force of the boxing training device employing of using at present is a Displacement Measurement, and the action time of Displacement Measurement and power, it doesn't matter, and therefore the method for this measurement impact force exists the principle mistake; Used sensor is generally resistance strain gage, grating displacement sensor or electromagnetic induction displacement transducer, these sensors exist poor linearity, reaction velocity is slow, poor stability, defectives such as life-span weak point, cost height are because these sensor response speed are slow, so can't measure striking speed, this type of sensor need design special stabilized voltage supply and powers to it in addition, cost cost height not only, and can't realize energy-conservation target.
Summary of the invention
The objective of the invention is to overcome the inaccurate major defect of existing displacement sensor impact force, utilize impulse principle to realize measuring impact force and adopt state-of-the-art piezoelectric film sensor in the world today, the output charge of this sensor is directly proportional with its size that is hit, reaction velocity is very fast, assurance has very high measurement accuracy and measuring speed, the cost of this sensor is lower, need not independent power supply, can energy savings.The present invention has adopted the SoC microcomputer system in addition, use the liquid crystal display displays measured parameter, with the voice output of sound circuit realization to measured parameter and prompting, not only can measure dynamics, but also can measure striking speed, multinomial training quota such as degree of reaction, the training data of trainer every day can be recorded in the database, can inquire about contrast at any time, and historical data is shown, also can come out with printer prints.
To achieve these goals, by the following technical solutions:
1) impacting a plurality of piezoelectric film sensors of installation on the target body;
2) described piezoelectric film sensor and signal conditioner, SoC microcomputer system, sound circuit, LCD, LED light constitute a complete dynamics, speed, degree of reaction detection control system;
3) by the software and hardware of described detection control system realize to each piezoelectric film sensor to each corresponding impact force electrical signal converted detect, AD conversion, demonstration, voice count off and the trainer sent the voice suggestion sound that difference impacts the position.
Description of drawings
Fig. 1 is a kind of complete machine theory diagram of measuring the detection system of impact force based on impulse principle.
1 one kinds of software flow patterns of measuring the detection system of impact force based on impulse principle of Fig. 2 corresponding diagram.
Operation sequence of the present invention and the course of work (referring to Fig. 2) are: will impact the position to each earlier and calibrate before testing, the purpose of calibration is also identical in order to guarantee that each impacts position output valve after being subjected to the impacting of identical power. After calibration has been carried out, select " elementary ", " middle rank ", " senior " arbitrary rank by keyboard, select then test " intensity ", " speed ", " degree of reaction ", " air exercise " menu, choose rear click OK button and just can train. Arbitrary impact the position and impacted after, piezoelectric film sensor produces corresponding output voltage according to the size of being impacted, the SoC micro computer is patrolled and examined the sensor output voltage signal that impacts inside, position, convert the analog voltage signal of patrolling and examining to data signal, the speedometer that impacts continuously for twice calculated and show and realize voice counting by speech chip by liquid crystal display, and be recorded in the database.
Good effect of the present invention is: be the momentum that impacts owing to what detect 1,, and therefore all accurate than existing any impact force meter; 2, because the piezoelectric film sensor reaction speed that the present invention adopts is fast, therefore not only the dynamics of impacting can be measured, the speed that impacts continuously can also be measured, and trainer's the training quotas such as degree of reaction; 3, the piezoelectric film sensor of using with the present invention need not to power for its independent designing voltage regulator power supply, and the totle drilling cost of training airplane is reduced, and also meets the green energy conservation policy.
Embodiment
As shown in Figure 1, a kind of detection system based on impulse principle measurement impact force comprises SoC microcomputer system 1, piezoelectric film sensor 2, signal conditioning circuit 3, keyboard 4, LCD display 5, LED light 6, sound circuit 7, audio amplifier 8, mini-printer 9, microcomputer interface 10, power circuit 11.
Detecting the different piezoelectric film sensor 2 usefulness leads that impact the position links to each other with signal conditioner 3, signal conditioning circuit 3 is given SoC microcomputer system 1 with signal of sensor conditioning back, the SoC single-chip microcomputer carries a high-speed A/D converter, digital signal after AD changes can show by LCD 5 after treatment passes through sound circuit 7 and audio amplifier 8 realization voice count off simultaneously, can also indicate the position that is impacted by LED light 6.
Must be pointed out that above-mentioned example is just made an indefiniteness to the present invention and illustrated.But person of skill in the art will appreciate that, do not departing under aim of the present invention and the scope that can make various modifications, replacement and change to the present invention, these modifications, replacement and change still belong to protection scope of the present invention.
