The magnetic core material digital identity card device comprises two portions including a magnetic core type identity recognition code block and a magnetic core type identity recognition code block data reading head. The magnetic core type identity recognition code block is installed on the bottom portion of the card device by adopting a screw installation mode. The magnetic core type identity recognition code block data reading head is installed on the front end of a five-prevention computer key having the card device information reading function through a reading head housing slot. The device can be applied in the 'five-prevention computer key' for preventing 'false switching-off and false switching-on, load switching-off and switching-on, point grounding, ground power transmission, and false electrification' of a code reading and writing system in a power system, and can be used to improve the reliability of the five-prevention computer key on field apparatus identity recognition code block reading and writing operations in the electromagnetic environment and the magnetically-conductive environment.
Description
Technical field
The utility model belongs to field of relay protection in power, is specifically related to prevent that the reading code of specialized equipment-" the five anti-computer keys " of " mistake minute is closed by mistake, loaded deciliter, band point ground connection, band ground power transmission, mistakenly entering into charged " from writing in decoding apparatus.
Background technology
In electric system, prevent in the system of specialized equipment-" five anti-computer keys " of " mistake minute is closed by mistake, loaded deciliter, band point ground connection, band ground power transmission, mistakenly entering into charged ", the reliable recognition of device identity is power station net safe operation, power equipment safety operation, personnel's handling safety reliable guarantee, and meaning is very great.
Personnel, by the anti-computer key of five anti-terminal downloads operation orders to five, hold five anti-computer keys and enter operation area.Check the identity code before operating area, equipment, circuit, only having could be to the operate in operational zone in the situation that the code block information of storing in the five anti-computer keys is consistent with the code block information configuring on lockset on operational zone.Five anti-computer pins piece read heads send specific continuous magnetic field, make to close on identification code block internal inductance coil-induced, the information exchange that is pre-stored within identification code block inside is crossed to magnetic approach and be fed back to five anti-computer key read heads, carry out identity validation.Separately, five anti-computer key read heads can adopt same mechanism to rewrite buying the inner identity information of piece.
If reading code is wrong, go to the wrong way region or carry out wrong operation, its result will directly threaten personal safety and device security, further threaten the security of operation of electrical network, therefore improve five anti-computer keys whether correctly the reliability of readout code block message be one of precondition of power grid operation safety.
The code block recognition system of at present most of five anti-computer keys all adopts telefault contactless.
Adopt in this way, have following several respects problem:
1. conformity of production, reliability can not guarantee.
Owing to adopting the manufacture craft of Wound-rotor type, for guaranteeing to obtain reliable and stable magnetic field, telefault can reach hundreds of circles, and because installing space is little, so wire diameter is less than 0.03mm.Easily occur because packing colloid shrinks the situation that causes coil metal silk to break carrying out when encapsulation in later stage.
Separately, because coil finished product too small (diameter is less than 10mm) weight kicks the beam, in encapsulating encapsulation, due to buoyancy, there will be the situation of non-horizontal positioned, cause and reduce useful flux area, weaken signal intensity, cause and read difficulty.
2. read head produces magnetic line of force skewness, causes reading writing information difficulty.
Because five anti-computer key read heads adopt Gramme winding, the magnetic line of force is distributed as nonuniform magnetic fields.Magnetic field that coil produces has quite a few to be dissipated into useless region, weakens the reading capability of read head to identification code block.
3. under magnetic conduction environment, can not complete reading or rewriting of identity code internal information.
Because identification code block is often installed near magnetic conductor and inner.The magnetic field magnetic circuit that causes five anti-computer keys to produce changes, and has weakened by the field intensity of identity code Inside coil, and causing can not reading and writing code block message.
4. under complex electromagnetic environment, read or rewrite in the process of identity code internal information and be easily interfered.
Because identification code block is often arranged near grid power primary equipment, electromagnetic environment very severe, the wire-wound inductor of nonuniformity field intensity is very easy to receive external disturbance.Easily cause reading code to write the mistake of code.
Summary of the invention
