Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the present invention provides an induction type protective net device for sports ground, which includes five modules, namely, a pressure induction module 10, a capacitance change module 11, a detection circuit module 12, a numerical analysis module 13, and a numerical display module 14.
The working process of the five modules is that, the pressure sensing module 10 feels the change of the net body 4 caused by external balls and the like, the net body 4 is composed of a plurality of capacitors, the shape of the net body 4 is changed, namely, the gaps between the capacitor plates of the local part are changed, so that the change of the capacitors is caused, the change of the capacitors sensed by the circuit module 12 is converted into corresponding electric signals to be output, the position and the size of the deformation of the net body corresponding to the change of the electric signals can be obtained through the numerical analysis module 13, and finally the electric signals are displayed through the display module 14 to obtain the required numerical values.
As shown in fig. 2, the pressure sensing module 10 of the present invention includes a plurality of vertical rods 1, a binding block 2 is disposed at a lower end of each vertical rod 1, an anti-falling block 3 is disposed at an upper end of each vertical rod 1, a net body 4 is connected between adjacent vertical rods 1, an upper pull wire 5 is disposed at an upper end of each net body 4, a lower pull wire 6 is disposed at a lower end of each net body 4, two obliquely downward tensioning steel wires 8 are connected to an upper end of each vertical rod 1, and a binding pin 9 is connected to a lower end of each tensioning steel wire 8.
The upper end of the vertical rod 1 is connected with two downward inclined tensioning steel wires 8, so that the installation stability of the net body 4 is effectively guaranteed, and the detection of deformation is enhanced by the tightened net body 4.
As shown in fig. 2, the pressure reducing rings 7 are provided at both ends of the upper wire 5 in the present invention.
The pressure-reducing ring 7 effectively solves the trouble of overlarge central pressure because the upper stay wires 5 are gathered together under the influence of the gravity center of the net body 4 to cause overlarge pressure.
As shown in fig. 3 and 4, the net body 4 of the present invention includes a flexible net surface 401, a metal membrane 402 tightly attached to the flexible net surface 401 is connected to a rear end of the flexible net surface 401, a rear steel plate 403 is disposed behind the metal membrane 402, and an air gap 404 is disposed between the rear steel plate 403 and the metal membrane 402.
The plates of the capacitor in the structure of the mesh body 4 are the metal diaphragm 402 and the rear steel plate 403, and the medium is mainly air in the air gap 404. When the flexible mesh 401 is deformed by a force, the metal diaphragm 402 is deformed, and at this time, the air gap 404 between the metal diaphragm 402 and the rear steel plate 403 becomes smaller, so that the capacitance value becomes larger.
As shown in fig. 3 and 4, the metal diaphragm 402 of the present invention is formed by combining several metal pieces.
The metal small pieces of the multiple groups are convenient to obtain the position of capacitance change in detection, and the detection of the positions such as the height of the object thrown out can be realized.
As shown in fig. 5, the detection circuit module 12 of the present invention includes a detection bridge 1201, an output terminal of the detection bridge 1201 is connected to a signal amplifier 1202, an output terminal of the signal amplifier 1202 passes through a detection circuit 1203, an input terminal of the detection bridge 1201 is connected to a signal loading device 1205, an input terminal of the signal loading device 1205 is connected to an oscillator 1206, the oscillator 1206 is simultaneously connected to the detection circuit 1203, and an output of the detection circuit 1203 is connected to a filter 1204.
The specific detection process of the circuit is that when the capacitance value changes to cause the balance of the detection bridge 1201 to break, a differential voltage is generated at the moment, but a voltage signal is weak and needs to be amplified through the signal amplifier 1202 at the moment, the energy source of the bridge is the oscillator 1206, the signal of the oscillator 1206 is modulated onto the detection bridge 1201 through the signal loading device 1205 consisting of coils and output, the signal amplifier 1202 outputs the modulated signal and needs to be demodulated through the detection circuit 1203, the detection circuit 1203 generally adopts a phase-sensitive detection circuit at the moment, the demodulated signal of the detection circuit 1203 preferably adopts the signal generated by the oscillator 1206 which is the same as the input signal, and the required useful signal is obtained after demodulation through the filter 1204. The signal at this time passes through the signal processing module 1301 and is displayed on the numerical value display module 14.
As shown in fig. 5, the numerical analysis module 13 of the present invention mainly includes a signal processing module 1301 operated by a computer.
The signal processing module 1301 mainly analyzes how large the impulse corresponds to the different capacitance value changes and the position where the corresponding deformation occurs.
As shown in fig. 5, the two capacitors in the detection bridge 1201 are capacitors formed by connecting two adjacent metal chips and the rear steel plate 403.
The arrangement of the plurality of groups of capacitors and the bridge is convenient for finding out the position of deformation, and the position induction of the invention is realized.
As shown in fig. 5, the filter 1204 in the present invention is a low-pass filter.
The signal output by the general detection is in a low frequency band, and a low-pass filter filters out high-frequency useless signals and only analyzes the useful signals, thereby facilitating the analysis process.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
