Abstract
The invention discloses a meter management technique of a centralized meter reading system, which mainly comprises the following step: providing an intelligent data collector and an intelligent data concentrator in the system. The meter management technique has the advantages that the structure is reasonable, the concept is skilful, the concept of 'intelligent management' is introduced, and the intelligent identification technique is adopted between the collector and the concentrator, thereby reducing the maintenance workload of an apparatus.
Description
Technical field
The present invention relates to a kind of low-voltage power user automatic meter reading system (calls in the following text: centralized meter-reading system).Relate in particular to a kind of automatic meter reading system that has intelligent acquisition and discern automatically.
Background technology
There are problems in the automatic meter reading system (low-voltage power user electric energy meter automatic meter reading system) that is applied to power supply enterprise at present, and outstanding a bit is exactly that collector can not be discerned ammeter automatically.In traditional collector, the parameter of ammeter is manually imported by the operator, and collector can only be gathered the data of the ammeter of parameter input, and can not make a response to the increase or the replacing of ammeter.After ammeter increased or changes, the operator must increase or change the parameter of corresponding ammeter in the collector, otherwise collector just can't be gathered the data of the ammeter that increases newly or change.When having a considerable amount of ammeters can't gather its data because collector does not have its parameter in the system, the practicality of this system just greatly reduces.
Summary of the invention
The objective of the invention is to, a kind of meter gauge management technique that can discern the automatic meter reading system of ammeter automatically is provided.
For achieving the above object, the present invention adopts following technical scheme: a kind of meter gauge management technique of automatic meter reading system mainly comprises following steps: an intelligent data acquisition unit and intelligent data concentrator are provided in this system.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: the present invention is rational in infrastructure, be skillfully constructed, introduced the notion of " intelligent management ", between collector and ammeter, adopt intelligent identification technology, significantly reduced the workload of plant maintenance, the present invention has the positive effect of the following aspects performance:
1, realizes checking meter robotization, need not the people and check meter, increase work efficiency.
2, realize table meter management automation; Need not manually to change parameter, guarantee the complete of data.
3, save later maintenance cost; Need not manually-operated, save cost of labor; Do not produce communication fee, save operating cost, have promotional value.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is the system architecture synoptic diagram that relates among the present invention.
Embodiment
The present invention is made up of " electric energy meter intelligent data acquisition unit (call in the following text: collector) ", " intelligent data concentrator (call in the following text: concentrator) " and " main platform management software (call in the following text: main platform software) " etc.Equipment adopts differentiated control, framework clear and definite.Mainly be used between collector and the electric energy meter, reduce the workload of system maintenance personnel site operation.
Collector is to the automatic recognition function of ammeter: in the communication link that collector and ammeter RS485 constitute, collector is a host computer, and ammeter is a slave computer, and by collector initiatively, ammeter is replied during communication.The address of its host computer of storage (collector) in the ammeter.
1, collector regularly sends inquiry message in link, after ammeter receives inquiry message, its decoding is extracted the address of collector, the address with the host computer of its storage compares then, if identical then do not reply, difference is then sent response message in this way.After collector received response message, the communication that message decoding is extracted ammeter was underground, the address of this ammeter was stored in the address table of its slave computer, and the expression collector had been discerned this ammeter after collector was finished this operation.
2, collector makes marks the unsuccessful slave computer of communication by timing meter reading function and its all slave computer communications, and accumulative total Communications failure number of times.When the communication number of times reaches one in fact during numerical value, illustrate that this ammeter breaks down or is removed, collector is deleted this ammeter from its slave computer address table.
3, after ammeter is received the inquiry message of host computer in the link, adopt competition mechanism to reply.The implication of competition mechanism is: if ammeter finds that communication link is in idle condition, then link is set to the communication busy condition, sends response message then.Competition mechanism can guarantee to have only all the time in the communication link slave computer to reply.
4,, then represent this collector fault or be removed that ammeter empties the address of its host computer when the host computer of being stored in the ammeter during at the appointed time not with the ammeter communication.
Collector and ammeter are discerned the other side by this intelligence operation, can reduce system maintenance personnel's maintenance workload in practical operation significantly, for normal, the efficient operation of system provides technique guarantee.
