Order, is then issued Remote drive command or automatic switching drive command by network channels such as power dispatch data networks
To the remote termination in transformer station, the measure and control device in transformer station is driven through substation network again by remote termination, finally through observing and controlling
Device outputs the triggering that contact realizes remote operation scene cue, by voice message and keeps certain prompt time,
Detect whether scene also has personnel by infrared induction equipment simultaneously, the purpose for reminding Field Force is reached, as work on the spot people
After member all withdraws, laser fence is opened, it is ensured that be remotely controlled again or switching operation after safety.It is of the present invention in order to illustrate
Technical scheme, illustrates below by specific embodiment.
Fig. 1 shows that power station remote provided in an embodiment of the present invention operates the structure of laser fence alarm and prompt system, is
It is easy to illustrate to illustrate only the part related to the embodiment of the present invention.
The power station remote operation laser fence alarm and prompt system that the present embodiment is provided includes main website 1 and transformer station 2, described
Transformer station 2 includes remote termination 21, measure and control device 22, sound prompt device 23, infrared induction equipment 24 and laser fence 25, described
Sound prompt device 23, infrared induction equipment 24 and laser fence 25 are located at the primary equipment side of transformer station, as shown in Fig. 2 institute
Stating sound prompt device 23 includes loudspeaker 231, auxiliary reclay, the connection of auxiliary reclay controlling loudspeaker 231 or pass
Close.The measure and control device 22 includes outputing contact 221, and the contact 221 of outputing is gone here and there with the auxiliary reclay, loudspeaker 231
Couple into working power, the folding condition of the auxiliary reclay is outputed contact 221 and controlled by the measure and control device, it is specific real
Now, the auxiliary reclay includes coil HJ and two couples of contacts HJ1 and HJ2, it is described output contact 221 and the centre after
Working power two ends are linked into after the coil HJ series connection of electrical equipment, one pair of which contact HJ1 is connected in parallel on and described outputs 221 liang of contact
End, another a pair of contact HJ2 is linked into working power after being connected with the loudspeaker 231, and contact is outputed by tactile when measure and control device
After hair, coil HJ is passed through electric current, and contact HJ1 and HJ2 are closed, and such loudspeaker cut-in operation power supply can be with continuous firing.It is described
The one end of remote termination 21 is connected with the main website 1 by dispatch data net, the other end of the remote termination 21 and the measure and control device 22
Connected by transformer station's in-house network.
In the present embodiment, the remote termination 21 is used to receive the Remote drive command for coming from main website regulation and control center 11
Or come from the automatic switching drive command of main website AVC systems 12, and the order that will be received is forwarded to measure and control device 22, institute
The contact 221 of outputing for stating measure and control device 22 is connected with the auxiliary reclay of sound prompt device 23, and measure and control device 22 is used for basis
Remote drive command or automatic switching the drive command control for receiving are outputed contact 221 and are closed, so that control voice
Suggestion device 23 works.The infrared induction equipment 24 is connected with measure and control device 22, and infrared induction equipment 24 is used to detect once
Device context whether someone, and testing result is fed back into main website 1 by the measure and control device 22, remote termination 21.The laser
Fence 25 is also connected with measure and control device 22, when the speech play of sound prompt device 23 is finished and infrared induction equipment 24 is detected
Nobody when, laser fence 25 is opened, when the laser sent once laser fence 25 is blocked, the signal that laser fence will be detected
Main website and sound prompt device are passed to, and sound prompt device is sent alarm 23.
The embodiment of the present invention is realized and works as main website by setting sound prompt device, infrared induction equipment and laser fence
When regulation and control center is remotely controlled operation or main website AVC system automatic switching capacitors, can be with the voice of pre-cooling transformer station
Suggestion device, infrared induction equipment and laser fence, remind the staff at scene away from operation equipment, it is ensured that safety.It is preferred that
, in the sound prompt device, the loudspeaker 231 is also parallel with warning lamp 232, here by voice signal, electric signal, light
Signal triplicity sets during primary equipment straighforward operation to the staff that together, can effectively remind scene away from operation
It is standby, further increase the security in work.
When being operated for regulating and controlling centralized telecontrol, when implementing, it is provided with a remote control in main website end monitoring interface and carries
Show button, the prompting button outputs contact linkage with measure and control device, then by it is described output contact by a centre after
Electrical equipment is connected with the sound prompt device near primary equipment.When main website end is remotely controlled operation, main website end person on duty can be with
First operation indicating button, points out button to be driven auxiliary reclay to close by contact is outputed through measure and control device after triggering, live
Sound prompt device is connected, and points out field personnel's primary equipment to be remotely controlled operation, away from operation equipment, suggestion device
The prompt time for setting is 30s, the person on duty at main website end just remote control operation after 30s.
When AVC system automatic switching capacitors, set after AVC systems start switched capacitor program
The Program time delay of 30s, while when setting AVC systems send automatic switching drive command, contact is outputed in startup, drives voice message
Device work, point out scene staff's capacitor will switching, away from operation equipment.AVC systems send automatic switching drive
Move after having ordered 30s, switched capacitor action command is sent automatically, then the sound prompt device at scene there will be the time of 30s
Field personnel is reminded away from operation equipment.
When sound prompt device starts, in order to increase the reliability of alarm prompt, while being installed near primary equipment red
Outer sensing apparatus, for whether also having staff, and the result of sensing is fed back into main website near sensing apparatus.The present embodiment
In, the infrared induction equipment works with the sound prompt device with the period, and usually infrared induction equipment is in the shape that do not work
State, only while sound prompt device works, just starts infrared induction equipment, and infrared induction equipment is by self-sustaining 30s's
Time, voice message terminates after 30s, and infrared induction equipment is again switched off, and can so prevent infrared inductor anti-to main website
Feedback garbage.
After sound prompt device work and infrared induction equipment start, if there is work people near infrared induction equipment
Member, then infrared induction equipment can just sense that now the sensing normally opened contact of infrared induction equipment will be closed at once, so
Start a relay afterwards, after the coil conducting of the relay, its normally opened contact closure can so export a trigger signal
And measure and control device is back to, and the operating personnel at main website end are then fed back to by remote termination again, remote control or switching can be suspended
Action, it is also possible to regenerate Remote drive command or automatic switching drive command, voice is carried sound prompt device again
Show and timing, until prompt time terminates and when infrared induction equipment detects nobody, start laser fence, it is ensured that personnel will not lean on
Near operation equipment.
