Specific embodiment
Below by specific embodiment, technical scheme is described in further detail.
As shown in figure 1, a kind of intelligent experimental teaching equipment, including experimental facilities part, data server, man-machine interaction
Device, camera device, acoustic-optic alarm and processor；
The processor connects the human-computer interaction device and is regarded for typing user profile, typing experimental data and broadcasting teaching
Frequently；
The processor connects the camera device to be used to shoot with video-corder user's experimentation and obtain face information to carry out authentication；
Test start when, starting device first, by human-computer interaction device typing personal information, by camera device and body
Part identifying system carries out recognition of face, and identification system is integrated in the system of equipment, is a kind of conventional authentication system
Whether system, verification is me, then carries out theory study by human-computer interaction device, grasps experiment points for attention and experiment is flowed
Journey, after completing above step, starts experiment.
The experimental facilities part include equipment body and it is some can quick despatch on the equipment body
Experiment component, the experiment component is with the exercisable parts of interactivity, each experiment component used in experimentation
Outer surface be respectively provided with Quick Response Code, 2 D code information is the link for recording the element function, student by scanning Quick Response Code,
Link is obtained, into thematic knowledge, the function of each part, principle, application method and use occasion and whole in understanding equipment
The operating instruction and points for attention of equipment.
The experiment component sets feedback unit, and the feedback unit can be operation button or switch or sensor, according to
Using the difference of position, using different specific modules, such as operation button forms level signal, and Operation switch forms level
Signal, if carrying out some shifting functions, can be used touch switch or range sensor etc., its object is to be capable of identify that behaviour
The generation of work.
Each feedback unit connects the processor, and the processor connects the data server, when operation experiments element
When, each feedback unit sends the processor that feeds back signal to unique mark, and the processor receives these feedback signals simultaneously
In real time to the feedback signal that has been received by according to receiving time-sequencing, at the same with the contrast number that stores in the data server
According to comparing, the arrangement that the correction data stored in the data server is formed by feedback signal under correct operating procedure
Sequence, once comparison process appearance is inconsistent, processor control acoustic-optic alarm is alarmed and is recorded the faulty operation and walked
It is rapid in detailed process, to sort and compare interval in real time and be less than two steps operation duration as one of proficiency examination data, lead to
Often with millisecond meter, feedback can be made to be directed to every single stepping, if operation is correct, without response, if operating mistake, sent
Alarm, so as to corrigendum in time.The faulty operation step of record, can take point, for example, mistake according to the quantity of error procedure
More than 5 times, fail；Mistake 3-5 times, passes；Mistake 1-2 times, it is good；0 mistake, it is outstanding.
The processor carries out time mark to the feedback signal for receiving, and calculates the time of adjacent two feedback signal
Difference, the standard time that is stored with the data server is poor, and the standard time is differed from by the experimental complexity of teacher voluntarily
Setting, is broadly divided into three to four grades, the processor by the time difference obtained by calculating and standard time it is poor compare,
The result of comparison is used as the two of proficiency examination data；For example, calculate the time difference it is poor much smaller than the standard time, be judged to it is outstanding,
Calculate the time difference it is poor less than the standard time, be judged to it is good, calculate the time difference it is poor equal to the standard time, be judged to qualifying, during calculating
Between difference it is poor more than the standard time, be judged to fail, the data can also be embodied using ratio.Sentence because each step has
It is fixed, score can be refined in each operating procedure, it is also possible to by whole operating procedure averageds, as overall behaviour
Make the embodiment of proficiency.
In other embodiments, an experiment duration can be rounded to compare, a final result is obtained.
The experimental data of human-computer interaction device typing examines described proficiency as experimental result examination data, processor
One of Nuclear Data, the two of proficiency examination data and experimental result examination data are calculated by the weight equation of setting, are obtained
Final experiment grade, weight proportion is determined by experimental nature and teacher.
During being tested, experimental procedure is fixed, and what student's needs did is exactly step by step will according to step
Each step is finished according to the rules, and being operated by feedback unit for operation experiments element is related in each step
Whether correctly judge, and the length of operating interval determines the proficiency of operation, judgment criteria immobilization is conducive to student certainly
Row improves experimental ability.
Respectively can the experiment component of quick despatch have the identification module of unique mark, install each on the equipment body
The position correspondence identification module of experiment component sets collection terminal, and each collection terminal is all connected with processor to judge to access in fact
Whether correct test element, the identification module can be Quick Response Code or electronic tag, and collection terminal corresponds to barcode scanning camera
Or e-tag reader.
There are button and switch in the experiment component, button and switch all have status information feedback device, for example, indicate
Lamp or signal lamp, for the state of the equipment of checking.
As shown in Fig. 2 specifically, the intelligent experimental teaching equipment is integrated fluid dynamics experimental device, the reality
Testing part of appliance includes starter, water tank, Draw off valve, filling pump valve, centrifugal pump, turbine flowmeter and some experiment tubes
