Background technique
With the continuous improvement of power system customer side acquiring electric energy information level, high voltage customer metering is generally using as follows
Technical solution: intelligent meter configuration is constituted industry with the mode of GPRS single channel or the twin-channel special transformer acquisition terminal of GPRS+230MHz
Formed, however metrological service, power supply company acquisition operation maintenance personnel by power information acquisition system progress novel maintenance when, often
It encounters main website and special transformer acquisition terminal end communication is normal, but the problem of electric energy meter acquiring electric energy information failure occurs.
There are mainly two types of the reason of acquisition failure: the first situation, intelligent electric energy meter failure, acquisition terminal can not obtain intelligence
It can table data information；Second situation, intelligent meter correspond to measurement loop and stop transport, and then the connect metering secondary terminal decompression of meter,
Defluidization, while also power loss, this kind of situation can also cause acquisition terminal to acquire intelligent meter number by RS485 to the meter reading battery of intelligent meter
According to failure.
For the first case, metering acquisition operation maintenance personnel needs to record failure electric energy meter corresponding user information, sends inspection
It repairs personnel to overhaul to scene, electric energy meter is replaced when can not overhaul.For second situation, this time of user's stoppage in transit
Road belongs to user's normal electricity consumption behavior, without processing.
However since technological means problem can not judge above two problem, so that professional O&M people must be sent
Member is judged at the scene to meter, is corresponded to circuit stoppage in transit if electric energy meter, is resulted in that operation maintenance personnel is unnecessary to send, increasing
Time, human and material resources cost are added, have reduced working efficiency, it is therefore necessary to necessary ancillary technique means be taken to solve
State problem.
Summary of the invention
It is mainly used for high voltage customer metering it is an object of the invention in place of overcome the deficiencies in the prior art, providing one kind to adopt
Collect the high pressure that professional O&M uses in the process, auxiliary power information acquisition system carries out efficient operation judgement to intelligent meter to use
Family three-phase intelligent electric-energy meter condition monitoring system and method.
The present invention solves its technical problem and adopts the following technical solutions to achieve:
A kind of high voltage customer three-phase intelligent electric-energy meter condition monitoring system, including electric energy meter, acquisition terminal, connection metering two
Secondary voltage end and intelligent electric meter condition judgment module, there are five terminals for the setting of intelligent electric meter condition judgment module, are connected in parallel meter
It measures three terminals at secondary voltage end, connect with information receiving end of intelligent meter alarm terminals interconnection and with acquisition terminal RS485
The transmission information terminal of mouth connection, electric energy meter connect metering secondary voltage end by conducting wire, and metering secondary voltage end passes through conducting wire
Intelligent electric meter condition judgment module is connected, intelligent electric meter condition judgment module connects electric energy by intelligent meter alarm terminals connecting line
Table and by RS485 connecting line 2 connect acquisition terminal, electric energy meter by RS485 connecting line 1 connect acquisition terminal.
Moreover, acquisition terminal is 230MHz acquisition terminal.
A kind of high voltage customer three-phase intelligent electric-energy meter state monitoring method, method and step are as follows:
Step 1, active reporting
(1) intelligent meter state monitoring module judges that meter corresponds to circuit by the electrification situation at acquisition metering secondary voltage end
Whether stop transport；
(2) the information that intelligent meter state monitoring module is sent by obtaining intelligent meter alarm terminals, record, storage electric energy meter
Operation exception information, report automatically；
(3) intelligent meter state monitoring module is sent abnormal by the information transmission interface being connected with the port acquisition terminal RS485
Exception information is sent to main website by the remote transmission channel between acquisition terminal and main website by information；
Step 2 passively reports
When remote collection exception, transmitting order to lower levels to acquisition terminal, it is corresponding that acquisition terminal obtains intelligent meter state monitoring module
Meter information judges that meter corresponds to whether circuit stops transport, at the same according to the event of record judge meter whether failure.
The advantages and positive effects of the present invention are:
The design of the invention is scientific and reasonable, system structure is simple, passes through electric energy meter, acquisition terminal, connection metering secondary voltage
The mutual cooperation of end and intelligent electric meter condition judgment module effectively combines live real work situation, solves metering acquisition O&M
The occurrence of personnel's remote collection ammeter information fails, and is unable to judge accurately questions and prospect.Avoid operation maintenance personnel because that can not sentence
Disconnected line outage or electrical energy meter fault and caused by it is unnecessary send, effectively reduce high voltage customer metering acquisition operation maintenance personnel
Runing time cost improves work on the spot efficiency.
Detailed description of the invention
Fig. 1 is system connection figure of the invention.
