Description
Technical field
The present invention relates to power circuit technical field, be specifically related to a kind of ground wire supervisory systems and method.
Background technology
In electric system, ground wire is called as line of saving one's life.Reasonable extension dismounting ground wire is the most important condition ensureing all kinds of operation field person, device security, is also power department leaders, the safety practice paid close attention to most of site safety aufsichtsrat.Due to the reason of technical development, ladder of management and personnel's sense of responsibility, for many years, continue to use traditional extensive management and control mode always, cause following result: 1, ground wire maintenance maintenance is not in place, cause ground wire ' in spite of illness ' operation, do not have " line of saving one's life " effect at the scene; 2, individual persons seeks easy to operate, arbitrarily mounts, and even mistake is suspended on neighbouring charging equipment sometimes, causes personal injury, equipment scaling loss.So strict management and control ground wire is the important schedule of electric power safety supervision department at different levels.
In the last few years along with development in science and technology, safety management severization, some department's new technology development, apply the supervisory systems of some associated ground lines, have received certain benefit.But due to networking foundation have high input, the factor restriction such as execute-in-place is dumb, function is incomplete, cause the process of applying slow, social benefit is not obvious.Therefore, hyundai electronics infotech R & D design is adopted to go out the modular ground wire supervisory systems of a perfect in shape and function, easy to use, flexible operation, reliable operation, be widely used in all kinds of electric operating on-the-spot, ground wire is made really to play the effect of " line of saving one's life ", being then the very big respect to on-the-spot line operator workman's body and life, is also the abundant guarantee that power equipment safety runs.
There is following defect and deficiency in existing ground wire supervisory systems: 1. need to install grounding body, set up earth wire pile and fixing RFID, work on the spot amount is large, and, corollary failure probability artificial by the external world increases.2. can not flexibly at the optional position of requirement of engineering extension/dismounting ground wire.3. need to disconnect ground wire electric conductor, cause ground wire to occur obvious cut-off point, easily cause trouble spot to increase, ground wire is damaged.4. volume is large, embedded independently GPS, GPRS module.5. energy consumption is high, often charges, and operation maintenance is numerous and diverse.6. adopt RFID to combine the section of judgement, field apparatus can not judge duty voluntarily, needs background server process, easily causes erroneous judgement probability once large.7. need Distribution GIS support, database previous work amount is large, works limited.8. task is single, by all means ground wire.
Because electronic information technology docks imperfection with electrical production running technology, and real demand understanding that is on-the-spot to electric operating, especially vast remote poverty-stricken area medium and small electric power enterprise operation field is grasped not in place, causes occurring that ground wire supervision is not in place.Be mainly manifested in following 2 points:
Need the place that ground wire is set at every place all first will bury grounding body underground, do the fixing peripheral hardwares such as ground stud, also fixing wireless senser will be installed on ground stud.The responsible point of China's major part is many, line length, wide basic unit's electric power enterprise are then difficult to possess installing condition like this.
Want to play functions of the equipments at the power department intending installing ground wire management system, first will have the generalized information system Informational support possessing and cover full area under one's jurisdiction.When current China major part () electric system enterprise GIS at county level application not general, be difficult to penetration and promotion.
In sum, there is the illusory accident potential of disorderly hanging, arbitrarily layouting of ground wire for ground wire supervision in prior art, can not reach real-time monitoring.
Summary of the invention

The data received at the second sampled point are processed, obtain second group of state of earth wire data S2, and second group of state of earth wire data S2 and first group state of earth wire data S1 is contrasted, there will be four kinds of situations as shown in the table, can judge that this ground wire is in steady state (SS) or transition state accordingly, four kinds of situations are as shown in table 1:
Table 1 state of earth wire table
| First group of state of earth wire data | Second group of state of earth wire data | Result |
| Mounting | Mounting | Steady state (SS) |
| Mounting | Remove | Transition state |
| Remove | Mounting | Transition state |
| Remove | Remove | Steady state (SS) |
After said process completes, interval 30 second, on-site data processing platform 2 receives data with same flow process again, and carries out process to the two groups of data again received and report to host computer 3.

S5, the interval schedule time, repeated execution of steps S2 to S4, judges that described ground wire is steady state (SS) or transition state.
8. a kind of ground wire monitoring and managing method according to claim 7, it is characterized in that, described step S2 also comprises: described first state S1 and the second state S2 comprises mounting state and dismounting state, if the absolute value of the vertical drop of sampled point is greater than first threshold, it is then mounting state, if the absolute value of the vertical drop of sampled point is less than Second Threshold, then it is dismounting state.
9. a kind of ground wire monitoring and managing method according to claim 7, it is characterized in that, described step S4 is specially: if the first state S1 is identical with the second state S2, then ground wire is steady state (SS), if not identical, is then transition state.
10. a kind of ground wire monitoring and managing method according to claim 7, it is characterized in that, described step S1 also comprises: gather Lighting information, and send to the single-chip microcomputer (12) in harvester (1);
Single-chip microcomputer (12) receives Lighting information, and judges whether current time is daytime according to Lighting information, is if so, then single-chip microcomputer (12) power supply, single-chip microcomputer (12) is worked; Otherwise single-chip microcomputer (12) does not work.
