Abstract
The utility model relates to information acquisition equipment for an electric energy meter based on an EPON (Ethernet Passive Optical Network) and relates to the technical field of information acquisition of the electric energy meters. The information acquisition equipment comprises a PON (Passive Optical Network) unit and an optical fiber interface. The information acquisition equipment is characterized by further comprising a 485 communication module connected with a system control chip of the PON. By using the information acquisition equipment, the system control of an optical network unit of a kilomega terminal system based on the EPON can be realized, and the requirements for specific service processes such as automatic data logging, charge control, ordered electricity consumption, terminal installation, information acquisition, electricity utilization inspection, customer analysis, and the like can be effectively achieved.
Description
Technical field
The utility model relates to a kind of electric energy meter information acquisition equipment, more specifically says a kind of electric energy meter information acquisition equipment based on EPON that relates to.
Background technology
EPON (EPON) based on Ethernet adopts point to multipoint configuration, and the passive fiber transmission mode provides multiple business on Ethernet.In an EPON, do not need the agreement of any complexity, light signal just can be sent to the final user exactly, also can be concentrated from final user's data to be sent to central site network.In Physical layer, EPON uses the ether PHY of 1000BASE, simultaneously on the transmission mechanism of PON, control and optimize between each optical network unit and the optical line terminal (OLT) burst data and communicate by letter and communicate by letter by the MAC control command that increases newly with real-time TDM, because passive optical network unit sends datagram in the time slot of oneself, therefore not collision does not need CDMA/CD, thereby makes full use of bandwidth.In addition, EPON is by realizing that in the MAC layer 802.1p provides QoS.
485 interfaces are that the transmission range of RS232 has been done extension, this interface is simple and practical and transmission is reliable, this technology is very ripe, at present, electric energy meter 485 interfaces of domestic production are the basic configuration standards, and electric energy meter is followed the company standard DL/T 645 (multifunctional electric energy meter communication protocol) of State Grid Corporation of China by the signal of 485 interfaces transmission.
On the prior art basis, advance 485 interface functions with integrated in the optical network unit, while descending realization DL/T 645 communication protocols in the embedded software of optical network unit, up realization Q/GDW 376.1-2009-main website and acquisition terminal communication protocol stipulations, just can realize of the transmission of the information of electric energy meter at the EPON platform, realize acquiring electric energy information and the list-directed real-time of electric energy, solve traditional electric energy meter, manually check meter, the inconvenience that power utility check brought effectively realizes automatic data logging, take control, ordered electric, terminal is installed, information acquisition, power utility check, the requirement of the concrete operation flow of customer analysis or the like.Can be widely used in the construction of intelligent grid.
Summary of the invention
