Fig. 1 is the network structure of native system; Fig. 2 is the structural representation of ground the end of a thread; Fig. 3 is the vertical view of Fig. 2; Fig. 4 is the structural representation of wireless interface pile; Fig. 5 is the left view of Fig. 4.
Number in the figure: 1 ground wire dead lock, 2 earth connection management hosts, 3 five anti-main frames, 4 ground studs, 41 magnetic beads, 42 bolts hole, 5 ground the end of a thread, 51 bolts, 52 tongue tubes, 6 wireless routers, 7 network controllers, 8 earth connections.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment:
Embodiment: referring to Fig. 1-5, the comprising of present embodiment based on wireless network transformer substation grounding wire intellectualized management system:
Be arranged at the ground wire dead lock 1 that is used for earth connection is carried out locking in the security tool cabinet, described ground wire dead lock is by 2 controls of earth connection management host, and described earth connection management host is connected with five anti-main frames 3;
Be arranged at the wireless interface pile 4 of job site, earth connection 8 is connected on ground the end of a thread 5, be provided with RFID identification chip on described ground the end of a thread, wireless interface pile and the ground wire dead lock, described ground the end of a thread feeds back to described five anti-main frames 3 with being connected with off-state of described wireless interface pile by wireless router 6, network controller 7.
Described wireless interface pile 4 is provided with magnetic bead 41 and bolt hole 42, and described lead 5 is provided with the bolt 51 with described bolt hole coupling, and lead is provided with the tongue tube 52 by described magnetic bead control conducting and disconnection.
In specifically being provided with, every earth connection 8 all is connected with ground the end of a thread 5, and RFID identification chip is installed on ground the end of a thread, is used for identifying the unique number of earth connection.And RFID Wireless code sheet identification circuit and blocking mechanism are installed on each ground wire dead lock 1, when local the end of a thread is suspended in the screens of ground wire dead lock 1 appointment, Wireless code sheet identification circuit on the ground wire dead lock will recognize code value, thereby identification earth connection identity also can be with correct ground wire locking.Ground wire dead lock 1 can be installed in the ground wire cabinet of toolroom, and it is extremely convenient to install.After five anti-main frames 3 are authorized, the earth connection locking that ground wire dead lock 1 can maybe will also be returned the earth connection release of locking, thus be grounded the locking and the unlocking function of line.
Each ground wire dead lock 1 of earth connection management host 2 unified managements is reported the earth connection current states by communication port to five anti-main frames 3 simultaneously, carries out the release or the locking order of five anti-main frames.When the operation task of hanging earthing conductor was arranged, five anti-main frames 3 were by the selected earth connection of earth connection management host 2 releases, and non-selected earth connection then still is in blocking.When being articulated to the on-the-spot wireless interface edge of a field 5 and touching magnetic bead on the wireless interface pile 4, by the tongue tube 52 in the wireless base station apparatus on magnetic bead adhesive ground the end of a thread 5, contacting in the tongue tube, start wireless base station apparatus breaking dormancy state, carry out work, earth connection position that ground the end of a thread 5 articulates this point and numbering send 3 in radio network controller 7, five anti-main frames to by wireless router 6 and detect the real-time status of earth connection by wireless network, and are presented on the interface intuitively.
The unique RFID coding is housed on the wireless interface pile 4, is used for identification, be articulated to on-the-spot ground the end of a thread 5 and touch wireless interface pile 4, utilize radio-frequency technique to read RFID information, determine numbering and particular location.
As shown from the above technical solution, when the scene needs installing earth connection action-item, earlier in five anti-main frame simulation previews, five anti-main frames are by the corresponding earth connection of earth connection main frame 2 order dead lock 1 releases, operating personnel take corresponding earth connection away, after taking earth connection away, on five anti-main frames 3 of transformer station, can real-time tracking see that corresponding earth connection is removed.When on-the-spot practical operation proceeds to when articulating certain earth connection, at first open the mechanical lock on the wireless interface pile 4, ground the end of a thread 5 is articulated on the ground stud and firmly after, the wireless module of ground on the end of a thread returns to five anti-main frames by the state of wireless network with earth connection again, can monitor in real time on the five anti-main frames promptly that the user mode of on-the-spot earth connection hangs up or take away.
The same site examining and repairing of working as finishes, when removing earth connection, after the operations staff removes temporary ground wire according to operation task, it is removed to monitor on-the-spot earth connection on five anti-main frames in real time, after the operations staff correctly places return with temporary ground wire, after ground wire dead lock 1 detects earth connection, information is reported in real time to earth connection manager main frame 2, earth connection manager main frame 2 is reported to five anti-main frames 3 again, just can monitor the correctly playback of on-the-spot temporary ground wire on five anti-main frames in real time.
In the process that operating personnel operate at the scene, the user mode of the on-the-spot earth connection of real-time tracking on five anti-main frame interfaces, the displacement situation and the task executions situation of the on-the-spot earth connection of the demonstration of clear and definite.
