Method of work of the present invention:
(1) playback state
When ground wire correctly leaves the interior assigned address of Intelligent instrument cabinet in, 12 Pin contacts that the input end of mobile earth wire watch-dog is connected are inserted in 12 pin sockets corresponding with this ground wire number, now the working power of the single-chip microcomputer in the mobile earth wire watch-dog and wireless sending module is connected, be that ground wire is in " being classified as state ", whether the position that single-chip microcomputer is deposited according to the definite ground wire of current potential coding is correct, if deposit correctly status indicator lamp L2 is luminous, otherwise alarm condition pilot lamp L3 is luminous, remind the staff to examine situation and correct a mistake operation.When ground wire leaves position correct in the Intelligent instrument cabinet in, playback when correct, Single-chip Controlling wireless sending module transmitted signal, the ground wire correct information that playbacks is sent on the ground wire management host, ground wire management host interface can show " playback of XX ground wire is correct ", after the ground wire management host confirms that the information received is errorless, " playback of XX ground wire is correct " that receive sent on five anti-machines, thereby realize release.
(2) carrying state
Ground wire needs the Pin contact of mobile earth wire watch-dog to extract the pin socket in the Intelligent instrument cabinet before using, now single-chip microcomputer and wireless sending module dead electricity, can't normally post a letter, the signal that the ground wire management host sends because receiving the mobile earth wire watch-dog, now judge that ground wire has left the Intelligent instrument cabinet, in handling process, ground wire is in " carrying state ".Ground wire needs the information of the installation position of appointment is downloaded in the single-chip microcomputer of mobile earth wire watch-dog before using, every ground wire has corresponding subroutine, only need to open corresponding subroutine when downloading, the numbering of the ground stud that modification will be installed, then burning program gets final product.Adopt the authorise downloads mode when opening subroutine, ground wire usage license staff needs individual account and password just can login ground wire to use administration interface to carry out down operation.Like this, ground wire of every use, the ground wire management host all can record detailed information: as ground wire number, ground wire leaves the precise time of safe tool/appliance cabinet, and licensor's information allows the ground stud of installing to number, in the process of using, whether misuse occurred, ground wire playback precise time etc.
(3) duty
After ground wire is transported to assigned address, first the Pin contact of mobile earth wire watch-dog is inserted on the pin socket of ground stud, if correctly green working station indicator L4 is luminous in the ground wire use location, otherwise red warning pilot lamp L5 is luminous, reminds the staff to examine situation and corrects a mistake.After ground wire is attached on the ground stud of appointment, be that ground wire is in running order, the Single-chip Controlling wireless communication module is posted a letter, by ground wire, in running order information sends to the on-site wireless receiver module, the on-site wireless receiver module is successively through the field optical fibers transceiver module, the master-control room optical fiber receiver-transmitter module transmits the in running order information of ground wire to the ground wire management host in master-control room, ground wire management host interface display " the XX ground wire is installed on the XX ground stud ", side by side line management main frame sends to five anti-machines by the information of " the XX ground wire is installed on the XX ground stud ", five anti-machines are according to the corresponding disconnecting link of numbering locking and the disconnector of ground stud.
Used ground wire will be put back into the position of appointment in the Intelligent instrument cabinet, after ground wire is deposited, the Pin contact of mobile mobile earth wire watch-dog is inserted in corresponding pin socket, after only having the ground wire playback correct, five anti-machines just receive " playback of XX ground wire is correct " signal, just relevant switch and disconnecting link of release.
Under normal circumstances, the just release associative operation of rear five-preventing system until all ground wires all correctly playback, guarantee that the switching on earth wire accident can not occur; If ground wire is removed, also be not put back in the Intelligent instrument cabinet, but because the maintenance circuit is badly in need of power transmission, in this case, at first relevant responsible official need to confirm complete removal of the on-the-spot ground wire used, and then can adopt the mode of advanced authorization release to carry out release, the operation of combined floodgate power transmission.
When downloading, the mobile earth wire watch-dog adopts the authorise downloads mode, be that ground wire usage license staff needs individual account and password just can login ground wire to use administration interface to carry out down operation, ground wire of every use, the ground wire management host all can record detailed information: as ground wire number, ground wire leaves the precise time of safe tool/appliance cabinet, and licensor's information allows the ground stud of installing to number, in the process of using, whether misuse occurred, ground wire playback precise time.
