Description

A kind of GPRS forwarding units of electric-power centralized meter reading system
Technical field
It the utility model is related to the operation of power system and the technical field of maintenance, more particularly to a kind of electric power centralized automatic meter-reading The GPRS forwarding units of system, it is mainly used in the data of meter-copy collector and uploads to main website from meter-copy device.
Background technology
In domestic existing power information collection communicating system, acquisition terminal generally use wireless public network is as uplink communication Mode.Using the existing GPRS communication networks of China Mobile, all exchange information of acquisition terminal and main of collection pass through China Mobile data communication services center, apply for VPN private networks between mobile data service center and distribution center of power supply administration, and Central master station is established in distribution center of power office, all terminal devices are connected to the center by GPRS network and mobile data center Main website, realize that terminal connects with the real-time online of main website.
Due to the limitation of wireless public network coverage, in addition there is communication base station in some regional landforms based on hills Signal does not cover or the situation of signal extreme difference, causes these regional part low-voltage collecting meter reading terminal, negative control terminal, distribution transformer terminals Some basements of installation do not have signal, and causing to gather main website can not normal copy reading acquisition terminal data.
Solution of the current power terminal device market to problems, it is endless in the prevalence of transmission data delay, data Drawback, the effects such as whole, site operation is complicated, jitter, poor compatibility are unsatisfactory.Cause Fuzhou Prefecture collection main website without The problem of method normal copy reading acquisition terminal data, do not solved effectively always, can not more meet the electricity consumption that Guo Wang companies propose The overall goal of information gathering " full collection, control in full ".
There are a variety of solutions the country at present to solve wireless public network (GPRS, CDMA, 3G, 4G) blind area solution:
First, wireless public network extended line is done using RS485
The area such as Fujian proposes to use 485 extension systems, the wireless module of acquisition terminal is extended to by RS485 modes Taiwan area has the region of wireless public network signal;This scheme needs to increase RS485 line construction links, right due to needing to transmit over long distances RS485 construction qualities, job site environmental requirement are stricter.The limitation such as the transmission range of RS485 lines, transmission rate simultaneously Influence the popularization of this scheme.
2nd, extended using medium voltage power line carrier wave as wireless signal
Some medium-voltage carrier producers, propose using medium voltage power line carrier system extension wireless public network network (GPRS, CDMA, 3G, 4G) blind area;Because the problems such as safety problem of medium-voltage carrier, the construction management of medium-voltage carrier coupler, O&M, has a strong impact on this The offer of scheme.
3rd, extended using low voltage power line carrier as wireless signal
The country, Guo Wang low pressure carrier waves producer using low pressure carrier wave technology it is also proposed that realize prolonging for wireless public network signal at present Stretch.Low pressure narrowband carrier can not meet in communication reliability, communication speed, the scene limitation such as anti-interference《Q/GDW 1372- 2013》The requirement of the wireless public network network signal acquisition rate 99.8% of middle requirement.
For problem above, a kind of raising acquisition terminal transfer rate of urgent need development presents the low terminal of a maintenance cost again and set It is standby.By the use of the equipment, can effectively solve the electricity consumption acquisition terminal (meter-copy collector) that GPRS signals do not cover area Data transmission problems, collecting device is set to be in optimal communications status all the time, it is online to effectively improve power information collecting device Rate, the data acquisition for intelligent grid construction provide basic guarantee.
The content of the invention
The defects of to overcome prior art, the technical problems to be solved in the utility model there is provided a kind of electric power concentration and copy The GPRS forwarding units of table system, it greatly improves acquisition terminal transfer rate, and on-site maintenance cost is than relatively low.
The technical solution of the utility model is:The GPRS forwarding units of this electric-power centralized meter reading system, the forwarding unit Including:
Proximal device and remote equipment;Proximal device is arranged on concentrator nearby and connected by ethernet line and concentrator Connect, remote equipment is arranged on GPRS signals compared with strong position, and power taking is easy in the position;
When concentrator reports metering main website data, data interaction is carried out by ethernet line and proximal device, near-end is set After the standby data for receiving concentrator, remote equipment is forwarded to by power line PLC, remote equipment sends out data by GPRS module It is sent to metering main website;
When metering main website issues data to concentrator, data are sent to by remote equipment by GPRS module, remote equipment will Data are forwarded to proximal device by power line PLC, and after proximal device receives data, concentrator is transferred to by ethernet line.
When reporting metering main website data due to concentrator, data interaction is carried out by ethernet line and proximal device, closely After end equipment receives the data of concentrator, remote equipment is forwarded to by power line PLC, data are passed through GPRS moulds by remote equipment Block is sent to metering main website;When metering main website issues data to concentrator, data are sent to by remote equipment by GPRS module, far Data are forwarded to proximal device by end equipment by power line PLC, after proximal device receives data, are transferred to by ethernet line Concentrator;So the forwarding unit greatly improves acquisition terminal transfer rate, and on-site maintenance cost is than relatively low.
Brief description of the drawings
Fig. 1 show the circuit block diagram of the GPRS forwarding units according to electric-power centralized meter reading system of the present utility model.
Embodiment
