Use these many people to run and detect the examination device and can satisfy the run demand of training examination of 120 disposable people, to everyone realize accurate meter circle, timing, dynamic information and the historical information recorded that will detect the examination are in display and control system to have with low costs, the consumption is little, reliable and stable, manipulate advantages such as simple.
Description
Technical field
This utility model relates to a kind of detection checking device of running, and particularly relates to a kind of for ring
Many people of shape runway run detection checking device.
Background technology
Along with popularizing of running exercise, the mass distance running match race that many people participate in is increasingly
Many.In the unit such as army, school, the long-distance running that also can often organize number more is taken exercise and examines
Core.In these long-distance races, it usually needs kinestate and the examination to every running personnel
Achievement is tracked record.
Under existence conditions, record keeping personnel is typically by artificial balance and draws the form records such as form
The number of turns that running personnel are run, information gathering, data statistics, performance rating, effect analysis etc.
The most loaded down with trivial details, not only expend a large amount of human and material resources, there is also erroneous judgement and anthropic factor, shadow
Ring the accurate, objective, just of achievement.Such as: 60 people take an examination simultaneously, it is necessary to 30
Many people even people more than 60 carries out a pair two, man-to-man meter circle invigilator personnel, due to proctor
Member too much makes examination place seem more chaotic, and the accuracy of timing and meter circle often occurs artificially
Error, to the organization and administration of examination, examination result, the situation in many ways such as inspection of training effect
All cause bigger difficulty；Often there is judging by accident the situation of the number of turns oneself run with reference to personnel,
Examination can not restore examination process later, it is impossible to effectively grasps the base of trainer's physical training
Plinth data, it is impossible to launch specific aim group instruction.
Therefore, the detection checking device run for many people of endless track also begins to be occurred.From
From the point of view of prior art, there are two problems and be difficult to solve: one is when many people are simultaneously through detection dress
When putting, due to reasons such as signal block, cause the problem such as missing inspection, many inspection, flase drops；Two be
With electronic inductor with every running personnel or in wrist, this electronic inductor is supplied by battery
Electricity, exists that battery power consumption is relatively big, electronic inductor electricity shortage and the problem that lost efficacy.
For these reasons, it is necessary to provide a kind of many people for endless track detection of running to examine
Nuclear device, it is possible to accurately identify the identity label of each running personnel in many people run detection,
Reduce the power consumption of the electronic induction unit being worn on running personnel's health, and there is cost
The technical advantage such as low, reliable and stable.

Fig. 7 be this utility model for many people of endless track run detection checking device another
The composition diagram of embodiment.This checking device also sets up on the endless track away from runway finishing line
There are another many people to run detection checking device, are used for running personnel's unlawful practice of maintaining order at a public gathering, two
Many people run and detect checking device networking.
It is contemplated that test may have many people to participate in every time, and does not has that in test process
60 running personnel such as, are tested by many supervisors simultaneously, thus unavoidably
There will be some runnings personnel to run less, detour and the problem that do not has enough staff to exercise supervision,
So in this embodiment, this running detection checking device except arrange carpet trigger winding 72,
Card reader 74 and double-frequency directional antenna 73, outside display & control system 75, away from runway finishing line
It is additionally provided with another many people on the endless track of 71 to run detection checking device, is used for maintaining order at a public gathering
Running personnel's unlawful practice.In the present embodiment, in the annular race away from runway finishing line 71
Arranging picket's device on road, this picket's device arranges second carpet trigger winding the 82, second double frequency
Beam antenna 83 and the second card reader 84, in the sets of data that the second card reader 84 is collected
Passing to the second display & control system 85, the data that the card reader 74 of this sets of data and finishing line gathers are entered
Row relative analysis, determines number of times and time that running personnel occur near picket's device, maintains order at a public gathering
Running personnel the most in violation of rules and regulations, thus carry out effective monitoring.
In the present embodiment, picket's device is provided with the second display system 85, by wired
The data of picket's device collection are sent to the second display system 85 by mode.In actual applications,
People more than two run detection checking device can also networking, by wireless transmit by pickets dress
The data putting collection are sent to display system 75, so can save the second display system 85,
Cost-effective.
Based on above example, the many people for endless track that this utility model provides run inspection
Survey checking device, wake up electronic induction labeling task up by carpet trigger winding, complete after the most again
Enter dormancy, effectively reduce the energy consumption of electronic induction label；By double frequency electronic induction label
Launch signal and double-frequency directional antenna receiving signal, it is possible to effectively prevent from data transmission procedure goes out
Existing mistake, say, that card reader is to the skip of electronic induction label data and mispronounces phenomenon almost
Will not occur；And by arranging picket's device, additionally it is possible to running personnel in test process
It is monitored, the unlawful practice of picket running personnel, such as checks the detouring of running personnel, leak
Run and few running is.Compared with prior art, this utility model is reduced energy consumption, collection information
The plurality of advantages such as stable, timing error achievement that is little and that record is true and reliable.
The foregoing is only embodiment of the present utility model, not thereby limit of the present utility model
The scope of the claims, every equivalent structure utilizing this utility model description and accompanying drawing content to be made becomes
Change, or be directly or indirectly used in other relevant technical fields, be included in this utility model
Scope of patent protection in.
