Abstract
The invention relates to an automatic electricity meter reading method which comprises the following steps: configuring an Ethernet passive optical network, setting a micro gateway, setting an electricity meter data acquisition mechanism, displaying the electricity meter reading, performing real-time monitoring and querying the principle. In the past, the method related to the automatic electricity meter reading includes power line carrier, a wireless mobile communication network, a wired television coaxial cable and the like. Because the methods have the defects of instable data acquisition, high interference, high cost and the like, large-scale application cannot be obtained. The fiber to the home and the telephone, internet and wired television three-network integration are the development tendency of the technology and market, the provided method is based on the three-network integration, the automatic electricity meter reading is realized by utilizing the conventional fiber-to-the-home network, the line is not required to be transformed, and the remote automatic meter reading can be realized through the common teletransmission electricity meters and a micro gateway only.
Description
Technical field
The invention belongs to communication and electric power sciemtifec and technical sphere, relate to a kind of method and principle that realizes the ammeter automatic data logging with Ethernet passive optical network.
Background technology
Automatic copying electric meter is the technology that the power industry attempt realizes always, along with the increase of traditional manual metering cost, realizes that the automatic data logging of ammeter has very large realistic meaning and economic worth.At present, the electric power technology or having promoted and researched and developed has following several:
(1) realize the ammeter automatic data logging by mobile radio communication: its principle is to implant wireless transmitter module in ammeter, and ammeter data is sent to concentrator by wireless signal, the more unified Utilities Electric Co. that delivers to.The advantage of this method is not need laying-out, transmits simple.But shortcoming is also clearly, and SIM card need to be set, and transmission cost is high, and ammeter need to be done special transformation simultaneously, and overall cost compare is high.Simultaneously, wireless signal can be subject to the shielding of building structure, and the correctness of data is affected.
(2) realize the transmission of ammeter data by power line carrier technology: utilize the line of electric force that spreads all over, by modulator-demodular unit, the ammeter reading is delivered to Utilities Electric Co..Its advantage is simple, but because the voltage fluctuation of our country is large, causes that signal disturbs, and the data correctness that causes transmitting is affected.
(3) realize the ammeter automatic data logging by the concentric cable of radio data system: advantage is to utilize existing CHINA RFTCOM Co Ltd, does not need track remodelling, and shortcoming is complicated technology realization, and needing increases a lot of optional equipments, and integrated cost is high.
Along with popularizing of fiber entering household, phone, internet, CATV (cable television) " integration of three networks " will be the standard configurations of home dwelling.Bandwidth of an optical fiber can reach greater than 1Gbps, except can carrying phone, internet and cable TV signal, can also carry other value-added services.The present invention is exactly the value-added service that realizes one of them-ammeter automatic data logging.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of method of the ammeter automatic data logging based on Ethernet passive optical network, and technical scheme is as follows:
This programme provides a kind of solution of carrying out the ammeter automatic data logging by ready-made optical-fiber network, mainly forms (as accompanying drawing 1) by following part:
(1) server: be connected by the RJ-45 interface with FEP, installing optical fibres is registered one's residence, and how net merges the generalized information management softwares, gather ammeter data by FEP and user terminal, and realize the inquiry to the electric supply meter data, and to the monitoring of electric supply meter state.
(2) FEP: managing user terminal, configuring virtual LAN (VLAN) is set up the transmission channel between electric supply meter and server, by photoelectric conversion module, electric signal is converted to optical signal transmission to optical fiber.
(3) optical splitter and optical fiber: optic path passage.
(4) user terminal realizes that electro-optical signal and electro-optical signal conversion are set up and the communication channel of FEP, transmits ammeter information.
(5) miniature gateway: the private IP address that each ammeter is set, the setting data acquisition rate, set up data parity check mechanism, ammeter interface (RS485) Data Transport Protocol format conversion is become the Ethernet protocol form, set up data channel with user terminal and FEP, image data is transferred to server.
(6) ammeter: band RS485 interface, close with piconet and be connected, the ammeter reading is provided.
Beneficial effect of the present invention is: a kind of method of new ammeter automatic data logging is provided, has solved the existing poor stability of existing various ammeter automatic data logging scheme and expensive problem.In this programme, FEP, optical splitter and optical fiber, user terminal are all ready-made, do not need duplicate construction, as long as telemetering electric meter, miniature gateway, server and a management software just can be realized the automatic data logging to electric supply meter, and user's meter reading data is sent to Utilities Electric Co. by mobile communications network, construction cost is low.Because the method is by the fiber optic network image data, its stability and correctness also can be effectively guaranteed.
Description of drawings
Fig. 1 is the ammeter automatic data logging principle schematic in the present invention;
Embodiment
(1) the ammeter power consumption reads: the fiber entering household that operation is arranged on server is netted fusion integrated management software more, according to the communication port of the IP of the resident family address foundation of setting with miniature gateway, miniature gateway sends to ammeter and reads the power consumption data command, ammeter sends electric quantity data to miniature gateway, miniature gateway becomes the Ethernet protocol packet to this data-switching, be sent to FEP by the user terminal interface, server receives this data by FEP, send to Utilities Electric Co. by mobile radio communication, deposit simultaneously server database in for inquiry.
(2) by the historical power consumption of resident family's numbering inquiry ammeter: more the runtime server fiber entering household is netted and is merged integrated management software, inputs resident family's numbering, enquiry of historical data.
(3) monitor resident family's ammeter state: more the runtime server fiber entering household is netted and is merged integrated management software, clicks and opens the monitoring button, when resident family's power consumption appearance is abnormal, alarm lamp is glittering, record warning reason, click the warning message key, can show resident family's ammeter exception record.
Claims (1)
1. a method that realizes the ammeter automatic data logging based on Ethernet passive optical network, is characterized in that, comprising:
(1) configuration of Ethernet passive optical network: employing VLAN (VLAN) is set up the data acquisition channel between ammeter and server;
(2) miniature gateway: the private IP address that each ammeter is set, the setting data acquisition rate, set up data parity check mechanism, ammeter interface (RS485) Data Transport Protocol format conversion is become the Ethernet protocol form, set up data channel with user terminal and FEP, image data is transferred to server.
(3) ammeter data collection mechanism: adopt People's Republic of China's power industry standard " multifunctional electric energy meter communication protocol DL/T645 ", the data transmission channel of ammeter and miniature gateway is set up in design.
(4) ammeter data demonstration, Real Time Monitoring and inquiry: server can show multi-user's power consumption data in real time, enquiry of historical data, the statistical history data, and can Real Time Monitoring the abnormality of ammeter, as unexpected power consumption increase, the monitoring of the state such as rupture of line, circuit are unstable.
