Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that embodiment be merely to illustrate the present invention without For limiting the scope of the invention.Furthermore, it is to be understood that after having read content disclosed in this invention, this field skill Art personnel can make various changes or modifications the present invention, and such equivalent forms equally fall within protection scope defined by the present invention Within.
State of ground wire acquisition system acquires ground wire real-time status by state of ground wire acquisition device with wireless transmission method, and State of ground wire data are transferred to the hard contact output device of Intelligent earth wire by wired or wireless transmission mode.Intelligent earth wire connects firmly Point output device is rack device, is equipped with front panel and postposition panel, and front panel is equipped with LED display, is used to indicate System mode, power supply status, communication state and output state without source contact, postposition panel be equipped with DC24V power input terminal, The state of tearing open outputs loop terminals to line extension, ground wire pile No. information outputs loop terminals, system mode open entry loop terminal, and RS485 communication terminal, RS232 communication terminal and RS422 communication terminal.The hard contact output device of Intelligent earth wire is additionally provided with MCU number According to processing unit.The hard contact output device input 24V direct current of Intelligent earth wire works for device hardware circuit.
The ground wire extension state of tearing open outputs circuit and ground wire pile No. information is outputed circuit and designed using passive contact switch.According to figure 3, passive contact switch includes driving coil, electromagnetic module and passive opening and closing contact, and hardware circuit is issued to driving coil and driven After pulse voltage, driving coil generates electromotive force, the electromagnetic field effect that electromotive force changes to electromagnetic module, and electromagnetic module drives nothing Source is opened and closed the movable contact movement in contact, open and close two states is exported, to realize the description of data 0 and 1.It is passive to connect It is physically-isolated for putting between switch internal driving coil and passive opening and closing contact, and the two cannot directly transmit data-signal, only After driving coil can be passed through by voltage drive, the electromotive force of generation is changed into electromagnetic field and is applied to electromagnetic module to drive out The passive opening and closing contact movement in portion inside the Pass, realizes data one-way transmission, guarantees system data information high security.
System mode open entry loop is designed using optical coupling isolation circuit, acquires the work of the hard contact input device of Intelligent earth wire State.The hard contact output device of Intelligent earth wire is obtained by RS485 communication terminal, RS232 communication terminal, RS422 communication terminal The state of ground wire data that state of ground wire acquisition device provides.And by the MCU data processing unit of apparatus system to state of ground wire Data are handled, and MCU data processing unit issues driving instruction according to state of ground wire data, and control drive circuit module makes nothing Source contact switch motion is consistent passive contact switch output state with state of ground wire data.Such as obtain 1 state of ground wire Data are 001, then the output state after the movement of passive contact switch respectively corresponds as closure, closure, off-state.
The hard contact input device of Intelligent earth wire is rack device, is equipped with front panel and postposition panel, preposition face Plate is equipped with LED display, is used to indicate system mode, power supply status and communication state, it is defeated that postposition panel is equipped with AC220V power supply Enter terminal, DC24V output terminal, ground wire extension and tears state open entry loop terminal, ground wire pile No. information open entry loop terminal, system work open Make state output loop terminals, ethernet communication interface, RS485 communication terminal, RS232 communication terminal, RS422 communication terminal with And wireless communication antenna interface.The hard contact input device input AC220V power supply of Intelligent earth wire works for device hardware circuit, and DC24V, which is exported, by terminal supplies the hard contact output device of Intelligent earth wire.Ground wire extension tears state open entry loop and ground wire pile No. letter open Open entry loop is ceased to design using optical coupling isolation circuit, the ground wire that the hard contact output device of acquisition Intelligent earth wire provides hang state of tearing open and Ground wire pile No. information data.Working state of system output loop is retouched using relay design by two-way relay output loop Four working conditions for stating the hard contact output device system of Intelligent earth wire, are respectively as follows: normal operation, misoperation, system reset It is reset with system data.The hard contact input device of Intelligent earth wire collects ground wire extension and tears state open and ground wire pile No. information data passes through Ethernet communication is transferred to anti-error host.
According to the anti-mis-logical that system is arranged, line extension tears state open to anti-error host over the ground and ground wire pile No. information carries out logic and sentences It is disconnected, and Real-time image display ground wire extension tears state and ground wire pile No. information open, issues alarm signal to the ground wire for not meeting logical requirements Number, remind operator to carry out defect elimination processing.Only ground wire extension tears state open and ground wire pile No. information complies fully with anti-error host system It unites after the anti-error logical requirements of setting, ground wire extension tears operation task open and just calculates completion.
The hard contact output device of Intelligent earth wire describes the extension of ground wire using 1 to 6 without any one in source contact Tear state open, selectable, the hard contact output device of Intelligent earth wire tears state open without source contact using 3 to describe the extension of ground wire, the One passive contact state indicates enabled and outputs ground wire pile No., and rear two passive contact states indicate that ground wire extension tears state open, specifically Shown in being described as follows:
000 expression ground wire is to tear state open;
001 indicates that ground wire is extension state, and ground wire pile No. is constant;
010 indicates that ground wire is extension state, and ground wire pile No. is constant;
011 indicates that state of ground wire is abnormal;
100 expression ground wires are to tear state open;
101 indicate that ground wire is extension state, and ground wire pile No. changes;
110 indicate that ground wire is extension state, and ground wire pile No. changes;
111 indicate that state of ground wire is abnormal.
The hard contact output device of Intelligent earth wire describes ground wire pile No. information without source contact using at least 6, selectable, The hard contact output device of Intelligent earth wire describes ground wire pile No. information without source contact using 12, can at most describe 4096 ground Line pile No..The isolation acquisition that earth wire hangs state of tearing open is realized by above system and its working method, is being grounded line While condition intelligentization manages, the network information security is improved.
More than, embodiments of the present invention are illustrated.But the present invention is not limited to above embodiment.It is all Within the spirit and principles in the present invention, any modification, equivalent substitution, improvement and etc. done should be included in guarantor of the invention Within the scope of shield.
