In order to more fully understand the technical content of the present utility model, the following technical solutions of the present utility model will be further described and illustrated with reference to specific embodiments, but are not limited thereto.
As shown in fig. 1 to 3, the infrared pull-up detection device of the utility model comprises two vertical rods 10, a mounting plate 20 arranged at the upper end of the vertical rod 10, and a cross rod 30 arranged between the two mounting plates 20; wherein the right mounting plate 20 is provided with an on-rod infrared sensor 411 for detecting an up-to-position and above the cross bar 30, and an under-rod infrared sensor 421 for detecting a down-to-position and below the cross bar 30; also comprises a control circuit 50 connected with the upper rod infrared sensor 411 and the lower rod infrared sensor 421; the control circuit 50 is also connected with a buzzer 51 and a display screen 52; the human head signal detected by the on-rod infrared sensor 411 is output to the control circuit 50 from the presence to the absence (when the chin part of the head of a student or athlete protrudes forward and the chin part is higher than the position of the cross bar, the signal of the on-rod infrared sensor 411 changes from the presence to the absence), and an upper counting signal is output to the control circuit 50; when the head signal of the human body detected by the under-rod infrared sensor 421 is from the existence to the nonexistence (when the top of the head of a student or an athlete is lower than the under-rod infrared sensor 421, the signal of the under-rod infrared sensor 421 changes from the existence to the nonexistence), a lower counting signal is output to the control circuit 50; the one-time up count signal and the one-time down count signal constitute a pull-up count. The control circuit 50 is of a conventional structure and generally comprises a microcontroller, a circuit board, a power supply, peripheral components of the microcontroller, and the like.
More specifically, the right mounting plate 20 is provided with an on-rod mounting block 41 for mounting the on-rod infrared sensor 411, and an under-rod mounting block 42 for mounting the under-rod infrared sensor 421. The right mounting plate 20 is provided with a horizontal chute 21 for mounting the upper rod mounting block 41 and a vertical chute 22 for mounting the lower rod mounting block 42; the rod mounting block 41 is provided with a rod clamping part 410 embedded in the horizontal chute 21 and a rod hand screw 412 in threaded connection with the rod clamping part 410; the lower rod mounting block 42 is provided with a lower rod clamping portion 420 embedded in the vertical chute 22, and a lower rod hand screw 422 in threaded connection with the lower rod clamping portion 420. The structure can adjust the horizontal position of the upper infrared sensor and the vertical position of the lower infrared sensor, so that the structure is convenient for athletes or students with different heights and different body shapes to use. And better flexibility is achieved.
More specifically, the number of the on-rod infrared sensors 411 is two (or three, four or five), wherein when any one of the on-rod infrared sensors 411 detects whether the head signal of the human body is from the present to the absent, an upper counting signal is output to the control circuit 50, and the on-rod mounting block 41 also adopts two or more, so that the distance between the plurality of on-rod infrared sensors can be adjusted. This can expand the detection range: the on-pole infrared sensor 411A closest to the crossbar 30 is higher than the crossbar 30 and overlaps the crossbar 30 in the horizontal direction, and the on-pole infrared sensor 411A closest to the crossbar 30 is detected only when the chin of a student or athlete is close to the crossbar and higher than the crossbar. The pull-up motion of the student or athlete may also change, the head may be far from the rail, the on-rod infrared sensor 411A closest to the rail 30 may not be detected, at this time, other on-rod infrared sensors 411B far from the rail, and chin parts of the student or athlete with their head protruding forward may also pass the on-rod infrared sensor 411, so that the change of the generated detection signal from the presence to the absence is counted as one. The number of the infrared sensors under the rod is two (or three, four or five), wherein the head signal of the human body detected by one infrared sensor 421 under the rod is from the existence to the nonexistence, and a lower counting signal is output to the control circuit once. This can expand the detection range: the student or athlete changes level after descent and a post infrared sensor 421 detects this and counts the number.
In this embodiment, the on-rod infrared sensor 411 and the under-rod infrared sensor 421 are correlation type infrared sensors; the mounting plate provided with the infrared sensor on the rod and the infrared sensor under the rod is one, and the other mounting plate on the left is provided with a light source corresponding to the infrared sensor on the rod and the infrared sensor under the rod, and is also fixed by adopting the mounting block 41A on the rod and the mounting block 42A under the rod.
In the present embodiment, an auxiliary sensor may also be employed, and an on-rod auxiliary sensor 61 (the same type of sensor as the on-rod infrared sensor) located above the on-rod infrared sensor 411, and an under-rod auxiliary sensor 62 (the same type of sensor as the under-rod infrared sensor) located below the under-rod infrared sensor 421 are also provided. False detection can be prevented, that is, when the detection signal of the on-rod infrared sensor 411 is valid, the on-rod auxiliary sensor 61 should detect a human head signal; the under-rod auxiliary sensor 62 should also detect a human head signal when the detection signal of the under-rod infrared sensor 421 is valid.
More specifically, the device further comprises a control button 59 connected with the control circuit 50, a communication module 58 and a pressure sensor 53, wherein the pressure sensor 53 is arranged at the handshake part of the cross bar 30.
More specifically, the cross bar 30 is provided with an anti-skid sleeve (not shown in the figures), and the pressure sensor is provided between the anti-skid sleeve and the cross bar.
More specifically, the vertical rod 10 is a square metal rod, and is coupled at a lower end to a base (not shown) provided, which is buried under or placed on the ground.
In other embodiments, auxiliary sensors may not be employed. Particularly when the pressure sensor is adopted, the on-rod infrared sensor and the under-rod infrared sensor have the front and rear time periods (such as front and rear 1-5 seconds) of signal generation, and the pressure sensor is not in a set range (the set range is generally the weight range of students or athletes), so that the pressure sensor does not operate effectively in pull-up.
In other embodiments, the on-pole infrared sensor and the under-pole infrared sensor are reflective infrared sensors; the mounting plate provided with the infrared sensor on the rod and the infrared sensor under the rod is one and can be left or right.
In summary, the mounting plate is arranged at the upper end of the vertical rod, so that the electronic components such as the sensor, the control circuit and the display screen are convenient to mount, and the stability is good. The installation block is further adopted to install the sensor, and the horizontal sliding groove and the vertical sliding groove are adopted, so that the horizontal position of the upper infrared sensor and the vertical position of the lower infrared sensor can be adjusted, and the sensor is convenient to use by athletes or students with different heights and different body shapes. And better flexibility is achieved.
