Twisted pair line connection is passed through, it is possible to achieve communication between ground wire management main frame and five anti-machines of transformer station.
The method of work of the present invention:
(1) playback state
When ground wire specifies position in correctly leaving Intelligent instrument cabinet in, the input of mobile earth wire watch-dog is connected
12 Pin contacts are inserted in the pin socket of 12 corresponding with this ground wire number, the now list in mobile earth wire watch-dog
Sheet machine is connected with the working power of wireless sending module, i.e. ground wire is in " being classified as state ", and single-chip microcomputer determines according to current potential coding
The position that ground wire is deposited is the most correct, if depositing correct, status indicator lamp L2 is luminous, on the contrary then alarm condition display lamp L3
Luminescence, reminds staff examine situation and correct faulty operation.During the position correct in leaving Intelligent instrument cabinet in of ground wire,
When i.e. playbacking correct, Single-chip Controlling wireless sending module sends signal, and the correct information that playbacked by ground wire is sent to ground spool
On reason main frame, ground wire management host interface can show " playback of XX ground wire is correct ", the letter that ground wire management host acknowledgement receives
Cease errorless after, " the XX ground wire playback correct " that receive is sent on five anti-machines, thus realizes unlocking.
(2) carrying state
Ground wire needs before using to insert the Pin contact of mobile earth wire watch-dog pin in Intelligent instrument cabinet
Extracting in Zuo, now single-chip microcomputer and wireless sending module dead electricity, it is impossible to normally transmit, ground wire management main frame is because receiving
The signal sent to mobile earth wire watch-dog, now judges ground wire already out Intelligent instrument cabinet, is in handling process, i.e.
Line is in " carrying state ".Ground wire needs the information of the installation position specified is downloaded to mobile earth wire watch-dog before using
In single-chip microcomputer, each ground line has the subprogram of correspondence, has only to open corresponding subprogram when of download, and amendment to be installed
The numbering of ground stud, then burning program.Using the when of opening subprogram authorizes downloading mode, i.e. ground wire to use perhaps
Can staff need individual account and password just can log in ground wire use administration interface be downloaded operation.So, often make
With a ground wire, ground wire management main frame all can record detailed information: such as ground wire number, ground wire leaves the essence of safe tool/appliance cabinet
Whether really time, licensor information, it is allowed to the ground stud numbering of installing, there is misuse, ground wire playback essence during use
The really time etc..
(3) duty
Ground wire is transported to specific bit and postpones, and first the Pin contact of mobile earth wire watch-dog is inserted into the pin of ground stud
On socket, if ground wire uses position correct, green working station indicator L4 is luminous, otherwise red warning display lamp L5 is luminous,
Remind staff to examine situation and correct mistake.After ground wire is attached on the ground stud specified, i.e. ground wire is in running order, single
Sheet machine controls wireless communication module and transmits, and information in running order for ground wire is sent to on-site wireless receiver module, on-the-spot
Wireless receiving module transmits, through field optical fibers transceiver module, master control room optical fiber receiver-transmitter module, the letter that ground wire is in running order successively
Ceasing the ground wire management main frame indoor to master control, ground wire management host interface shows " XX ground wire is installed on XX ground stud ",
Simultaneously the information of " XX ground wire is installed on XX ground stud " is sent to five anti-machines by wire management main frame, and five anti-machines are according to connecing
The corresponding disconnecting link of numbering locking of pile and disconnecting switch.
The position specified in used ground wire Intelligent instrument to be put back into cabinet, after ground wire is deposited, movement is mobile
The Pin contact of ground wire watch-dog is inserted in the pin socket of correspondence, and after only ground wire playback is correct, five anti-machines just receive
To " playback of XX ground wire is correct " signal, just unlock relevant switch and disconnecting link.
Under normal circumstances, after the most correctly playbacking until all of ground wire, five-preventing system just unlocks associative operation, it is ensured that band ground
Line combined floodgate accident will not occur；If ground wire has been removed, the most it is not put back in Intelligent instrument cabinet, but due to maintenance circuit
Being badly in need of power transmission, in this case, the director that is first correlated with needs the ground wire confirming onsite application the most all to remove, the most permissible
The mode using advanced authorization to unlock is unlocked, power transmission of closing a floodgate operation.
Use the when that mobile earth wire watch-dog downloading and authorize downloading mode, i.e. ground wire to use license staff to need
Wanting individual's account and password just can log in ground wire uses administration interface to be downloaded operation, often uses a ground wire, ground spool
Reason main frame all can record detailed information: such as ground wire number, ground wire leaves the precise time of safe tool/appliance cabinet, and licensor believes
Whether breath, it is allowed to the ground stud numbering of installing, there is misuse, ground wire playback precise time during use.
