Abstract

The utility model discloses a kind of portable service placement detector, it comprises the detector body being placed on opponents' half test point; Described detector body comprises sensor, and the output of described sensor is connected with CPU by filtering and amplifying circuit, A/D change-over circuit; The input of described CPU is also connected with button; The output of described CPU is connected with loudspeaker and display.Described detector body is of a size of 10cmX10cmX1cm (table tennis), 50cmX50cmX5cm (tennis).Intuitively whether reflection sportsman service is consistent with drill program by man-machine interface, auditory tone cues etc. for the data that the utility model can reset previous test point by button, and improvement sportsman serves a ball drill program.

Description

Portable service placement detector

Technical field

The utility model relates to sports science, and more particularly it is a kind of portable service placement detector.

Background technology

Table tennis, tennis service technology is the most basic in table tennis technology, the technology of most critical, require drop point, rotate, speed flexibility is changeable, but if ball cannot be dealt into the drop point that you want, speed and the rotation of ball will become meaningless, therefore whether inspection service falls into appointment drop point, positive role is had for lifting sportsman service technique level, also there is no a product detected for sportsman's service placement at present, function of the present invention is simple and practical, removable, when sportsman serves a ball, detector is placed on the other side Ban Qu appointed area, after sportsman serves a ball, ball falls on the detector, detector can send sound and light alarm and stored count, detector only need be moved to appointed area when needing to check another service placement by sportsman, reset counting, again service placement can be detected.

Summary of the invention

The purpose of this utility model is to provide the portable service placement detector of one that practitioner can be helped to record service placement.

It realizes by following technical scheme:

Portable service placement detector, it comprises the detector body being placed on opponents' half test point; Described detector body comprises sensor, and the output of described sensor is connected with CPU by filtering and amplifying circuit, A/D change-over circuit; The input of described CPU is also connected with button; The output of described CPU is connected with loudspeaker and display.

The standard size of described detector body is 10cmX10cmX1cm (table tennis), 50cmX50cmX5cm (tennis).

Usefulness of the present utility model is: 1. easy to use.As long as server places it at the other side half platform, want the drop point detected, just can realize the detection of service placement, when wanting the service detecting another one drop point, only need moving detector to assigned address.

2. precisely detect, easily extensible.This detector standard size is 10cmX10cmX1cm (table tennis), 50cmX 50cmX 5cm (tennis), specialty sportsman relies on good training and feel can control in drop point region little like this, but for beginner, possibly cannot accomplish to serve a ball so accurately, multiple standard detectors can be extended to a detector, so that detect more large-area drop point.

3. structure is simple, and all electronic components such as inner single-chip microcomputer are all encapsulated in standard module, and only need a battery, the service that can realize falling into detector is added up.

4. functional diversity.Repeat uninteresting service to be difficult to adhere to, this detector can have audio function, when service fall into specify reserved after, detector sends applause, encouragement sound etc., encourages in time to service personnel, confidently adheres to continuing exercise.

Intuitively whether reflection sportsman service is consistent with drill program by man-machine interface, auditory tone cues etc. for the utility model, and to serve a ball data analysis to sportsman, and improvement sportsman serves a ball drill program.

Accompanying drawing explanation

Fig. 1 is that the portable service placement detector sensor of the utility model arranges schematic diagram.

Fig. 2 is the utility model portable service placement detector arrangement schematic diagram.

In figure: opponents' half (being the other side half platform during table tennis) A; We is half-court (being our half platform during table tennis) B; Detector body C; Sensor 1; Filtering and amplifying circuit 2; A/D change-over circuit 3; Button 4; CPU 5; Loudspeaker 6; Display 7.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail, but this embodiment should not be construed restriction of the present utility model, only for example, simultaneously by illustrating that advantage of the present utility model will become clearly and easy understand.

As shown in drawings, when the service of server falls on detector body C, the weight of ball and impulse force can produce active force to the sensor 1 on detector body C, sensor generation deformation, thus impedance is changed, exciting current changes simultaneously, export the analog current signal of a change, this current signal outputs to analog-digital converter after amplifying circuit amplifies, and converts the data signal being convenient to process to output to CPU 5 (single-chip microcomputer) and carry out computing, counting by filtering and amplifying circuit 2 and A/D change-over circuit 3; And show by display 7, loudspeaker 6 sound production prompt.The standard size of detector body adopts 10cmX10cmX1cm (table tennis), 50cmX50cmX5cm (tennis).

Reset button 4 is pressed rear CPU5 and will automatically be reset by counting.

Move service detector for table tennis, workflow is summarized as follows:

1. load working battery.

2. detector body C is put into the drop point that the other side half platform is wanted to practise, and fixing.

3. the people that serves a ball serves a ball.

4., after ball falls into the detector body C being fixed on billiard table surface, ball produces active force to sensor 1, and sensor 1 produces corresponding induced signal, by process induced signal, show that service falls into appointed area, detection is sounded, encourage service people, increase counting simultaneously.

5. moving detector, detects other service placement, flow process after repetition the 2nd step.

It should be noted that: to those of ordinary skill in the art, can also make some changes or distortion to the utility model under the prerequisite not changing the utility model principle, this belongs to protection domain of the present utility model equally.
