Abstract
The invention relates to an intelligent electric energy meter with acquisition function, which is provided with an electric energy metering module, an LCD display, an LED indication, a power cut tripping function, an EASM module for security authentication, a multi-rate meter, an RS485 communication, an infrared communication and a microcontroller for sending commands and transmitting data to the modules, wherein the microcontroller is connected with an acquisition function module; and the acquisition function module is connected with the output interfaces of other electric meters in the electric cabinet. The invention facilitates the electric network reconstruction, avoids unnecessary waste, does not occupy excess space in the meter cabinet, and has the advantages of convenient installation, low cost and high safe reliability.
Description
Technical field
The present invention relates to a kind of intelligent electric energy meter, relate in particular to the intelligent electric energy meter of band acquisition function.
Background technology
On the basis of State Grid Corporation of China's " measure, check meter and expenses standard construction research " project achievement, State Grid Corporation of China's tissue has been worked out the intelligent electric energy meter series standard.Intelligent electric energy meter integrates numerous functions, have functions such as electrical energy metering, information stores and processing, monitoring in real time, control automatically, information interaction, can stop the arrearage behavior effectively, effectively in time the user be carried out modernized requirement of scientific management thereby complied with power department.
Collector is to be used to gather a plurality of electric energy meter electric energy information, and can with the equipment of concentrator swap data.The basic function of collector is to realize concentrator copying and accepting the electric energy meter data.The position of collector is between ammeter and the concentrator, i.e. ammeter--collector--concentrator.
In Automatic meter reading system, intelligent electric energy meter is installed in the centralized table case, and each table case has a collector to be used for electric energy meter electric energy information in the acquisition tables case.Because former old-fashioned table case is not reserved the space that collector is installed, in present electric network reconstruction, can only change the table case of reserving the collector space into or outside the table case, the little chest that can adorn collector is installed again, bring very big inconvenience and waste to electric network reconstruction.
Summary of the invention
The present invention will solve old-fashioned table case and not reserve the problem of making troubles and waste to electric network reconstruction in the space of installation collector, and a kind of intelligent electric energy meter of being convenient to electric network reconstruction, not wasting band acquisition function is provided.
Technical scheme of the present invention:
The intelligent electric energy meter of band acquisition function, have electric energy metrical module, LCD demonstration, LED indication, the power down function that trips, be used for EASM module, rate metering again, RS485 communication, the infrared communication of safety certification and the microcontroller that sends instruction, transmission data to each module, it is characterized in that: described microcontroller is connected with the acquisition function module, and described acquisition function module is connected with the output interface of other ammeters in the electronic box.
Further, described microcontroller is connected with the power line carrier module, and described power line carrier module is used for and the concentrator data communication.
Technical conceive of the present invention: the function of the function of intelligent electric energy meter and collector is gathered on the table, in electric network reconstruction, as long as an ammeter in the substitution table case just can be realized the function of collector, do not need to change a whole table case or an exception increase collector table case inadequately because of table case space.
Beneficial effect of the present invention: made things convenient for electric network reconstruction, avoided unnecessary waste, and easy for installation, with low cost, safe reliability is high, do not take unnecessary table case space.

Described microcontroller 1 is connected with power line carrier module 3, and described power line carrier module 3 is used for and the concentrator data communication.
Technical conceive of the present invention: the function of the basic function of intelligent electric energy meter and collector is gathered on the table, in electric network reconstruction, as long as an ammeter in the substitution table case just can be realized the function of collector, do not need to change a whole table case or an exception increase collector table case inadequately because of table case space.
When the present invention works, voltage, electric current are converted to sampled signal through senser element and send into computation chip after by Filtering Processing, computation chip is converted into pulse signal with energy signal and delivers to CPU and carry out the electric pulse collection, electric weight accumulative total and every computational analysis are handled, and its result is kept in the data-storing; CPU finishes function treatment such as safe LCD shows, LED indication, tripping operation power down function, multiple rate metering, RS485 communication, infrared communication simultaneously; Action need of the present invention is by strict ESAM module safety certification, the cryptographic algorithm of this ESAM module adopts the close algorithm of state, guarantee that data transmission security is reliable, meet national grid " intelligent electric energy meter message exchange secure authentication technology standard " requirement, acquisition tables is copied and accepted electric energy meter information in the table case by another road RS485, realizes communicating by letter by power line carrier and concentrator again.
The described content of this instructions embodiment only is enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as only limiting to the concrete form that embodiment states, protection scope of the present invention also reach in those skilled in the art conceive according to the present invention the equivalent technologies means that can expect.
