Brief description of the drawings
Fig. 1 is the people in the embodiment of the present invention applied to the training of distribution uninterrupted operation because of the structural representation of control system
Figure；
Fig. 2 is the structural representation of learning of embodiment of the present invention trainer and augmented reality device.
Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
Referring to shown in Fig. 1 and Fig. 2, the embodiment of the present invention provides a kind of people trained applied to distribution uninterrupted operation because of control
System processed, including：The one distribution job platform, system host and scene for carrying out distribution Job Operations for trainer builds module.
System host memory storage has scene to set database, scene set the view data of database including all distribution job platforms with
And all artificial scenes set data.
People applied to the training of distribution uninterrupted operation is because of the control system also scene structure including being connected with system host
Block, augmented reality device, learning training device, reliability evaluation system and people are modeled because of analysis system.
Scene structure module is used for the view data that a distribution job platform is chosen from scene setting database and some
Artificial scene sets data to build in the dummy model of distribution operating environment on distribution job platform, dummy model comprising multiple
The distribution operation of different work posts；Augmented reality device is used to dummy model being projeced into distribution job platform, augmented reality dress
Put including the Helmet Mounted Display being connected with system host, body-sensing camera and data glove, if being additionally provided with Helmet Mounted Display
Dry brain wave detection sensor.
Learning training device includes storing in normal data library module and learning training module, normal data library module
There is the operation of work post distribution operation or work standard, whether the distribution operation that learning training module is used for the current work post of training of judgement person is correct simultaneously
The related prompting of next work post distribution operation or work standard operation is provided to correct the mistake of trainer.
Learning training device also includes feedback of status module, and feedback of status module is used to be grasped according to the distribution operation of trainer
Corresponding feedback of status is provided, feedback of status includes get an electric shock feedback and bang feedback.
Reliability evaluation system is used to assess trainer not according to the accuracy of each work post distribution operation of trainer
With the reliability under work post distribution operation, when the accuracy of trainer some work post distribution operation is high, reliability is high, works as training
When the accuracy of some work post distribution operation of person is low, poor reliability.
People is used to gather eeg signal of the trainer under different work post distribution operations because of analysis system, obtains trainer
The mapping relations between brain wave and reliability under different work post distribution operations, and accordingly formulate the daily schedule of trainer
Reliability is improved to lower human-equation error.
Because the eeg signal of trainer can directly reflect the Mental Workload situation of trainer, Mental Workload is got over
Weight, distribution operation accuracy can be relatively low, poor reliability, still, and same trainer is mental negative under different work post distribution operations
Lotus is different, and the mapping relations between brain wave and reliability of the same trainer under different work posts are obtained by detection, so that
Corresponding daily schedule or operation scheme can be formulated.Such as advise that trainer completes the operation of certain several work post in practical operation
Afterwards rest a period of time, to mitigate Mental Workload, lower human-equation error, improve reliability.
In embodiments of the present invention, by setting multiple brain wave detection sensors to detect that trainer exists on trainer head
Eeg signal during learning training, and processing is filtered to eeg signal, then same trainer is found out in difference
The mapping relations between brain wave and reliability under work post.
People also includes a weather simulation device for being used to simulate state of weather because of training system, and weather simulation device includes drop
Hydrophone and blower fan, can simulate rainy state, make training live more true to nature, Consumer's Experience is more preferable.
Distribution job platform is the part power distribution network do not powered in the present embodiment, including overhead transmission line, cable, shaft tower, change
The infrastructure such as depressor, disconnecting switch, are available for trainer to carry out actual distribution Job Operations.According to hands-on needs,
Multiple other kinds of distribution job platforms are can configure to select for trainer.
According to the difference of distribution operation work post, such as pollard, removing foreign matter, replacing arrester in distribution, it is necessary to make
Dummy activity environment on industry platform, the arrester for such as increase in disorder branch or foreign matter, having damaged, and by these dummy activities
The image information of environment is converted to artificial scene and sets data, is stored in system host, is selected for trainer.
For the sake of trainer's safety, distribution job platform is without power supply, and feedback of status module can simulate electric shock, again
Hit etc. and to feel, when trainer's distribution Job Operations are improper, cause to get an electric shock, thump etc. consequence when, apply accordingly to trainer in time
Feedback, trainer is obtained more real impression, enhancing Consumer's Experience.
