Abstract

According to requirement of current criterion described in (2001) 3 document worked out by national ministry of education, the invention discloses method for identifying long distance running testees, and device for recording and measuring results. Main technical content is as following: in testing time of getting off the mark, end-point detector emits synchronous scanning signals sostenuto, and cycle of the signal is smaller than required standard error of measurement. Being in same cycle with the synchronous scanning signal, testee ID devices generate synchronous ID signals in progressive time differences. Thus, within a scanning cycle, the end-point detector can carry out answering communication with different testees so as to identify testees as well as record and measure results. The device includes main recording and measuring unit, starting gun, end-point detector, and testee ID devices. End-point detector is installed at finish line, and testees carry testee ID devices.

Description

Distance is run testee's recognition methods and its achievement recording measuring device

Technical field

What the present invention relates to is the electronic measuring device that measuring distance runs achievement, especially at be that distance in the physical stamina test is run achievement measure and recorded electronic device.

Background technology

The dash match, because the testee is all the time on runway separately, so by starting pistol after the record main frame send to start timing signal, transducing signal when each runway end point determination device is crossed its sensor with the experimenter is sent into the record main frame, main frame can write down testee's measuring-signal of each runway correspondence and identity and show, its electricity device be easy to realize.But also do not have a kind of at present at 800 meters and above distance race, cost is suitable for the long-distance running physical efficiency survey record device that each school applies, the difficult problem that its technical design ran into is: each physical stamina test person is not limited by runway, distance test more than a circle runs, and can occur that the testee breasts the tape simultaneously or the possibility of lasso, so how to differentiate each experimenter's identity, the corresponding games results of measuring and writing down them, and on cost, can be suitable for applying in each school, reaching the current specifications requirement of relevant physical health standard in (2001) No. 3 files of Ministry of Education of the state's body sanitation and art squad, is the gordian technique that realizes the long-distance running electronic surveying.
