Abstract
The invention relates to an electronic sensing device, in particular to a special sensing device for sandbag striking force and speed test in boxing training. Stress condition of the sandbag is sensed in real time by a pressure sensor which displays the striking force and speed for the convenience of adjusting training of athletes by trainers. The sandbag sensed by the pressure sensor in real time comprises a plurality of micro pressure sensors scattered on the stress face of the sandbag. The pressure sensors are connected with an ARM (advanced RISC machines) processor through an A/D (Analogue to Digital) data processing circuit and then connected with an LCD (Liquid Crystal Display) through an RS485 (Remote Sensing) interface to display data for the convenience of trainers and athletes to observe and consult.
Description
Technical field
The present invention relates to a kind of electronics sensing device, mainly is for the dedicated sense device that impacts sandbag strength and velocity test in the shadowbox.
Background technology
Raising along with the social interactions development, boxing develops rapidly in China, no matter is gymnasium or special sports school, or boxer's shadow is arranged in the sports meet, and at present also relatively backward to boxer's training, there are not meticulous training step and and plan, advanced.Therefore training effectiveness is lower.
Summary of the invention
The objective of the invention is electronics perception application of installation to overcome the deficiency that exists in the training in shadowbox, improve training effectiveness.Exactly, by the stressing conditions of pressure transducer real-time perception sandbag, will impact strength and Speed display out, and make things convenient for trainer that athletic training is regulated.
According to technical scheme provided by the invention, described slag-soil truck falls dregs dedicated sense device and comprises: a plurality of small pressure transducer that is dispersed in the sandbag stress surface, pressure transducer connects ARM by the A/D data processing circuit, connects LCD display by described RS485 interface again.
Described data processing circuit comprises metering circuit and A/D modulus conversion chip.Described metering circuit comprises end to end the first resistance, the second resistance, the 3rd resistance, replaceable resistance, the output terminal of the connected node Bonding pressure sensor of replaceable resistance and the 3rd resistance, the first resistance be connected the input end of connection A/D module of resistance.The connected node of the second resistance and the 3rd resistance is connected with the 0V level, the first resistance be connected the connected node of resistance and be connected with+4V level.
Advantage of the present invention is: a plurality of small pressure transducers are dispersed in sandbag surface (the suitable aspect of sandbag), receive and conversion through A/D conversion chip signal, realization sandbag surface changes accurately to be judged; Simultaneously the result can be connected with the ARM wireless transport module by the RS485 interface, and ARM is connected with LED display, and data are shown, and is convenient to trainer and the sportsman observes reference.
Description of drawings
Fig. 1 is one group of pressure transducer and data processing circuit schematic diagram.
Fig. 2 is slave computer processing links synoptic diagram.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
The quantity of the used pressure transducer of this sensing device is not limit, and is generally The more the better, and in this example, supposing has 5 sensors.Be evenly distributed on the stress surface of sandbag.
(1) such as Fig. 1, pressure transducer is under pressure, and produces the power simulating signal.Then with the power analog signal transmission that collects to the A/D module.
(2) A/D is the power analog signal conversion digital signal, processes with convenient.
Choice for use TLC2543 A/D conversion chip is 12 bit serial analog to digital converters of TI company, and use switching capacity one by one approximation technique is finished the A/D transfer process.Owing to be the serial input structure, can saving resource; And moderate, resolution is higher.
(3) A/D is transferred to arm processor with transformation result.
(4) slave computer is read once to send ARM to every the data of 30 seconds docking ports, and arm processor is made the relation curve of F and t in conjunction with two data, and strength and speed can be presented on the LCD screen like this.
(5) can rule of thumb reach sportsman's situation and at device threshold value is set, when not reaching threshold value, device can give the alarm, and this moment, the sportsman can take to adjust, and kept optimum condition.
Claims (4)
1. shadowbox sandbag dedicated sense device, its feature comprises: be arranged on 5 pressure transducers on sandbag surface, 5 pressure transducers are connected with RAM by the A/D analog-digital commutator respectively, are connected to LCD display by the RS485 interface at last.
2. sandbag dedicated sense device as claimed in claim 1, it is characterized in that described metering circuit comprises end to end the first resistance, the second resistance, the 3rd resistance, replaceable resistance, the output terminal of the connected node Bonding pressure sensor of replaceable resistance and the 3rd resistance, the first resistance be connected the input end of connection A/D module of resistance.The connected node of the second resistance and the 3rd resistance is connected with the 0V level, the first resistance be connected the connected node of resistance and be connected with+4V level.
3. sandbag dedicated sense device as claimed in claim 1 is characterized in that described microprocessor is ARM.
4. sandbag dedicated sense device as claimed in claim 1 is characterized in that modulus signal conversion equipment therefor is TLC2543 A/D conversion chip.
