This invention saves assembly cost and communication cost, improves manual meter-read efficiency, and has wide application.
Description
Technical field
A kind of electronic electric energy meter that is used for multi-user's generated energy acquisition.
Background technology
Present ordinarily resident, commercial user or industrial user's ammeter mounting means is divided into following several,
1, distributing is installed ammeter and is installed in the user place, this mounting means requires the staff of power supply administration to check meter to the doorstep for manual metering, for computing machine is checked meter, require each household all will draw telecommunication cable, thereby use telecommunication cable in a large number to automatic meter reading system.
2, half distributing is installed and is installed concentratedly with the electric supply meter of first floor, can improve the efficient of checking meter a little for manual metering, but efficient does not have the raising of matter, can a little save the use of telecommunication cable for the computing machine meter reading method, but quantity is few.
3, the electric supply meter in a centralized installation same storied building or a small pieces area is installed concentratedly at a place, efficient improves a lot for manual metering, but require the user to draw power supply to making land used from installing concentratedly, rolled up the consumption of feed cable, the wire casing that cable is installed for the city dweller building also increases considerably, and mentioning for the computing machine centralized automatic meter-reading is to save many telecommunication cables.
More than the mounting means of 3 kinds of the most normal employings at present, communication mode all adopts the communication mode of RS232 or modulator-demodular unit basically for computing machine is checked meter, all there is the low common fault of communication speed with upper type, the telecommunication cable use amount is big, the present invention adopts a kind of new communication mode, design a network type ammeter and reach and improve manual metering efficient, save feed cable, telecommunication cable, mounting material, improve the check meter purpose of reliability and meter reading efficiency of computing machine.
The mentality of designing of this programme is in a building or local section, design an electronic installation, this device is core with the microprocessor, constitute by communication module, human-machine interface module, data memory module, data processing module etc., this electronic installation is called network KWH meter, this ammeter can concentrate harvester to dock with multiuser electric energy meter, single user's electric energy meter or other electric flux, adopt and communicate by letter as the mode of high speed fieldbus such as CANBUS, PROFIBUS, Ethernet, the device that subordinate connect is linked to be a LAN (Local Area Network), gathers the electric flux of all unique users of subordinate.The electric energy information that collects can be stored on the spot, shows on the spot, inquire about on the spot, or by wired or wireless communication mode higher level's computing machine kilowatt meter reading-out system is transmitted electric energy data.With respect to communication mode in the past, the section that network KWH meter is administered, as long as adopt the wall scroll telecommunication cable just can constitute high-speed local area network, than before RS232 or the communication mode of modulator-demodular unit can save a large amount of telecommunication cables, increase substantially the node quantity (table is a node) of ammeter in the LAN (Local Area Network), increase substantially the speed of checking meter in the LAN (Local Area Network).Mode for manual metering, the staff is as long as just can inquire all users' of this network KWH meter subordinate electric energy information by this table, need only in that the electric energy information that the network KWH meter place just can inquire all users in this building is installed for skyscraper, again do not spend the information that every floor reads every table.And network KWH meter, can back up user's electric flux, reduce the loss that the damage because of subordinate's electric energy meter brings to greatest extent, can monitor the duty of the electric energy meter in the LAN (Local Area Network) simultaneously, in time the failure message in the LAN (Local Area Network) is fed back to the maintainer.
In a building, we can install the electric energy meter that has lan interfaces at each floor, and a network KWH meter is installed, and by netting twine all electric energy meters and network KWH meter are connected into LAN (Local Area Network).Than before technology, not only can save feed cable, telecommunication cable, installation wire casing etc., and can improve the reliability of electric energy meter metering, increase exponentially the efficient of checking meter.
Summary of the invention
The present invention adopts current advanced person's electronic technology, computer technology and the communication technology, design a network KWH meter, this electric energy meter is core with the microprocessor, configuration communication module, human-machine interface module, data processing module and data memory module, by the high-speed industrial fieldbus electric energy meter that subordinate connects or multiuser electric energy meter are linked to be LAN, each user's electric energy information also can be forwarded to higher level's kilowatt meter reading-out system to electric energy information by the mode of wired or wireless communication in query display should be netted on the spot.Network KWH meter has following characteristics:
1, its formation contains microprocessor;
2, its formation contains human-machine interface module on the spot, and the staff can inquire about the electric energy information that this network KWH meter is had jurisdiction over each user in the LAN (Local Area Network) by human-machine interface module, also can cancel human-machine interface module according to practical situations;
3, its formation contains communication module, and communication module adopts high speed fieldbus mode to communicate by letter with the subordinate electric energy meter, adopts wired or wireless mode to communicate by letter with higher level's kilowatt meter reading-out system;
4, its formation contains data processing module, and data processing module can store classifiedly the electric flux that receives, show or transmit;
5, its formation contains data memory module, and data memory module can be stored the electric flux of each user in this LAN (Local Area Network).
6, because of adopting the structure of LAN (Local Area Network), the increase of user's electric energy meter or deletion more need not be changed original equipment to the not influence of operation of system in the LAN (Local Area Network), have favorable expansibility and maintainability.
The more traditional centralized automatic meter-reading technology of network KWH meter is compared, and can reduce the power supply cost of regional area significantly, improves manual metering efficient, improves reliability and meter reading efficiency that computing machine is checked meter.Can monitor the running status of ammeter in the LAN (Local Area Network),, also can be used as the reserve measuring apparatus of unique user electric energy meter simultaneously, improve the reliability of metering in time with LAN (Local Area Network) internal fault report information maintainer.
