Description
Technical field
The present invention relates to sports test device more particularly to intelligent sit-up test devices.
Background technique
Sit-ups test is the conventional project in PE testing, and it is complete before the deadline to be typically required testee
Qualification is just calculated at the sit-ups of specified quantity.Existing frequently-used sit-ups test equipment includes: abdominal boards, low level biography
Sensor and high position sensor are provided with the fixed bracket of foot in the front end of abdominal boards, in the rear end close to abdominal boards
Side is disposed with low sensors and high position sensor, low sensors and high position sensor respectively with master control set phase
Even, there are counting unit and timing unit in master control set.When in use, testee lies on abdominal boards, will be double-legged
It is hooked on the fixed bracket of foot, then starts master control set, master control set opens countdown, while testee starts to face upward
Crouched seat, and testee steeves above the waist upwards during sit-ups, makes first to trigger low sensors, low level above the waist
Sensor forms signal one, and signal one is transferred in master control set, and then testee, which continues up, steeves above the waist, until
The height of steeving of testee's upper part of the body reaches the position of steeving of test request, can trigger high position sensor above the waist at this time, high
Level sensor forms signal two, and signal two is transferred in master control set, when signal one and signal two are successively successively transferred to
After in master control set, it is a satisfactory sit-ups that master control set, which judges current sit-ups, and master control set will
Form a useful signal, and the useful signal be transferred in counting unit, counting unit after receiving useful signal just
The number for receiving useful signal can be counted, testee will lie down downwards after completing primary movement of steeving and face upward
It has crouched on seat plate, during being lied down downwards, can first trigger high position sensor above the waist and form signal two, continue to lie down downwards
Low sensors will be triggered and form signal one, signal two and signal one are successively successively transferred in master control set, at this moment lead
Control device will not form useful signal, and counting unit would not be counted.In defined count down time, testee's weight
The movement lain of steeving-crouch again can complete test.But when stating sit-ups test equipment in use and being tested, due to quilt
When tester's both hands embrace head, elbows are easy to forward extend out and be located at the position in front above the waist, in this way in the process of steeving
In just will appear elbow prior to the upper part of the body trigger high position sensor the case where, it may be assumed that the upper part of the body of testee is not steeved also in place,
But its elbow has made high position sensor produce spurious signal two, and master control set can match after receiving spurious signal two
It closes signal one and forms false useful signal, counting unit can carry out false useful signal as true useful signal
It counts, can thus make the achievement tested out inaccurate.
Summary of the invention

It is fixed after the through-hole to align two-by-two with nut tightening.
Link block that can be online with Test Centre or the end PC, Test Centre or the end PC energy are provided in master control set 9
It is enough online by link block and master control set 9, it can be previously stored with the information of testee in Test Centre or the end PC, count
The achievement that counting unit is recorded can be fed back and be recorded by master control set 9 in Test Centre or the end PC.In master control set 9
In be additionally provided with voice broadcasting system and digital sound lever indicator, when starting master control set 9, voice broadcasting system is just
The voice of " starting to test " can be broadcasted remind testee test start, at the end of timing unit countdown, voice broadcast
System will broadcast the voice of " terminating test " to remind testee that test terminates, and during the test, digital sound is electric
Number of the flat every note of display will issue serge sound to prompt testee.
The working principle of above-mentioned intelligent sit-up test device is as follows:
When being tested, the both feet of testee catch on the fixed bracket 3 of foot, then by knee joint abut against bracket 4 withstand on it is tested
On two knee joints of person, staff by infrared-reflectance sensors infrared receiving and transmitting apparatus 10 and infrared reflective device 101
It is corresponding with the shoulder of testee respectively.
Then it is in running order to preset several corresponding infrared emission sensors for master control set 9, to make these
An infrared stroke adaptable with the supine position of testee is formed between in running order infrared emission sensor
Induction zone.Start master control set 9, master control set 9 starts infrared emission sensor and infrared-reflectance sensors simultaneously.Master control set
Timing unit in 9 starts countdown, and counting unit also starts simultaneously at work, and testee starts sit-ups at this time, is tested
During steeving upwards, the shoulder of testee moves upwards and first triggers infrared-reflectance sensors the upper part of the body of examination person
In infrared ray after form signal one, signal one is transferred in master control set 9, and then the upper part of the body of testee continues up
It steeves, passes through infrared stroke induction zone, during passing through infrared stroke induction zone, testee's from bottom to top above the waist
The infrared ray between each infrared emission sensor in infrared stroke induction zone can be successively blocked and crossed from top to bottom above the waist,
So that the case where being interdicted, being resetted again successively occurs in the infrared ray between each pair of infrared emission sensor, it is each right thus to make
Infrared emission sensor sequentially forms an independent signal respectively, with testee's process for steeving from top to bottom above the waist,
These independent signals are successively successively transferred in master control set 9, when master control set 9 is receiving signal one and and infrared stroke
A useful signal will be generated after the independent signal that each pair of infrared emission sensor successively transmits in induction zone, and should
Useful signal is transferred in counting unit, and counting unit counts the number of the useful signal received.Work as timing unit
At the end of countdown, master control set 9, which can control counting unit, to be stopped counting.Counting unit finally counts out the number come
The achievement of testee, staff can be by the track record on papery results, or is directly fed back by master control set 9
And it is recorded in Test Centre or the end PC.
The invention has the advantages that not only facilitating carrying, and testee can also be by adjusting extension board and sit-ups
The distance between plate and knee joint abut against the height of bracket to reach optimal test posture;Height is set just in master control set
It can make several infrared transmitters in running order and automatically form one between infrared remote receiver to lie on the back with testee
It rises and sits the adaptable infrared stroke induction zone of test process, without being manually adjusted, and infrared emission sensor and induction
Device and master control set match can determine automatically sit-ups movement whether standard, while can also accurately measure sit-ups
Number improves test accuracy rate to can effectively prevent cheating.
