Present invention has the advantage that：The present invention sets two-stage licensing scheme, it is necessary to which teacher agrees to just open electricity, Xue Yuanshi
Electricity can not be directly opened, safety operation problem is improved.Operating personnel can only be sent in request, student's request after electricity, and management is flat
The monitor of platform can be connected to the request.The monitor of management platform is connected in operating personnel's request after electricity, being capable of remote operation
1 level power supply control device inside opening device, and have suggestion device prompting, and device has after electricity suggestion device prompting.It is real
Instruct supervision teacher in room can the level power supply of remote opening 2, and have suggestion device prompting.
Practical training equipment such as some Training Room needs electricity consumption, and the operating personnel of the Practical training equipment click on Practical training equipment correspondence
Double empowerment management devices above request power on buttons, double empowerment management devices can feed back to the request comprehensive training room control
First management platform at center processed, when electricity prompting in the corresponding request of device that the first management platform have received some Training Room
Afterwards, if control centre agrees to electric on the actual training device, the power supply for opening correspondence real training chamber device is authorized, this is 1 grade of mandate, when
In first management platform mandate after electricity, there is " safety " condition prompting simultaneously on the double authoring system switch boards of Practical training equipment safety at the scene
And double authoring systems have signal to feed back to the corresponding teacher control centre of the actual training device, and this is pointed out in teacher control centre
The upper electricity of actual training device request, after teacher control centre receives request above electricity, if the actual training device is agreed to by teacher control centre
Upper electricity, opens the power supply of correspondence actual training device, and this is 2 grades of mandates, and after teacher control centre authorizes upper electricity, real training is set at the scene
There is " preparation " condition prompting on the standby double authoring system switch boards of safety, the operating personnel of the table apparatus see " preparation " condition prompting
Afterwards, the breaker inside the live double authoring system switch boards of Practical training equipment safety is opened, and has " RUN " condition prompting, this
Device can be run.
Device such as some Training Room does not need electricity consumption, and the operating personnel of the device click on the corresponding live real training of the device
" request power-off " above the double authoring system switch boards of equipment safety, and close the double authoring system controls of live Practical training equipment safety
Breaker inside cabinet, " RUN " condition prompting extinguishes, and the live double authoring systems of Practical training equipment safety can feed back to the request
Second management platform of Training Room teacher control centre, when the second management platform have received the corresponding request of some actual training device
After break prompt, teacher control centre disconnects the power supply of the actual training device, and " preparation " condition prompting extinguishes and request power-off is anti-
Comprehensive first management platform is fed to, after comprehensive first management platform receives request power-off, comprehensive first management platform disconnects should
The power supply of actual training device, " safety " condition prompting extinguishes.If the table apparatus runs into emergency and needs to break in the process of running
Electricity, can press " jerk " above the live double authoring system switch boards of Practical training equipment safety, and live Practical training equipment safety is double to award
Power system stops upper electricity.
Because the present invention realizes that comprehensive training room is 1 grade of mandate to the remote control of the power supply of double empowerment management devices；It is real
Existing site supervision teacher is 2 grades of mandates to the power supply of this pair of empowerment management device, it is to avoid what interference or equipment fault occurred
Misdelivery electricity, substantially increases electrical safety；When student asks to power, this programmable double empowerment management device can ask this
Negate feed comprehensive training room, supervise teacher equipment.
