Abstract
The utility model discloses an APN network system in the electric power scheduling. The APN network system includes monitoring stations(1), a control center (2), and a data server (3). The monitoring stations (1) and the control center (2) are connected with a data receiving and transmitting antenna (4) via a GPRS wireless network (3). The data receiving and transmitting antenna (4) is connected with a data server (6) via a USB wire (5). In a conventional network communication mode, a special-purpose line needs to be constructed, so the construction cost and operating cost are high, and the data server is wiredly connected with a mobile company GPRS network, if a break line fault occurs, the entire system can not work normally. The APN network system in the electric power scheduling can solve the above problems.
Description
Technical field
The utility model relates to power network schedule automation control field.
Background technology
Automation system for the power network dispatching has very high requirement to fail safe, can not adopt common wide area network transmission based on the data communication of the portable dispatch automated system of TD-SCDMA/APN private network, and must the highest APN private network transmission of special-purpose safe class; APN (Access Point Name) is the technological access via telephone line service of a kind of employing VPN (Virtual Private Network) that mobile operator provides; It is high that it is applicable to that safe class requires; The data transmission service that network security is had specific (special) requirements; Data center is through an APN access via telephone line commmunication company GPRS network; Adopt privately owned fixed ip address to carry out wide area between both sides' dlsw router and connect, and isolate, and on fire compartment wall, carry out IP address and ports filter with fire compartment wall; Adopt End to End Encryption between portable terminal and the server platform, avoid information possible leakage in whole transmission course; This kind communication modes is fine aspect real-time, stability and fail safe; But owing to need set up the APN special line; Construction and operation cost are higher; And be wired connection between data server and the commmunication company's GPRS network, in case faults such as generation broken strings, whole system maybe operate as normal.
Summary of the invention
The technical problem that the utility model will solve: provide APN network system in a kind of power scheduling to solve: need set up special line under the conventional APN network communication pattern; Construction and operation cost are higher; And be wired connection between data server and the commmunication company's GPRS network; In case faults such as broken string take place, whole system maybe operate as normal etc. problem.
The utility model technical scheme:
APN network system in a kind of power scheduling, it comprises monitoring station, control centre and data server, and monitoring station and control centre are connected to the data transmit-receive antenna through the GPRS wireless network, and the data transmit-receive antenna is connected to data server through the USB line.
Data transmit-receive antenna and data server are positioned at same room, the placement near the window of data transmit-receive antenna.
The beneficial effect of the utility model:
The data of monitoring station and control centre are inserted through the APN wireless private network under the GPRS; At data server end installation data dual-mode antenna; Connect data dual-mode antenna and data server realization data transmit-receive through the USB connecting line, the user is professional to moving application APN private network earlier.Move to the client distributes special-purpose APN, domestic consumer must not apply for this APN.The SIM that is used for the GPRS private network is only opened this special use APN, and other APN is used in restriction.After obtaining APN, distribute for all monitoring stations and control centre and move internal fixation IP number.The back monitoring station that powers on can directly initiate to be connected to data center with control centre.This communication modes control centre and monitoring station all are furnished with mobile Intranet fixed ip address, cut down the number of intermediate links, and stability strengthens; And all data are all moving the APN Intranet transmission of GPRS; Need not through public network, fail safe also is guaranteed, and has solved under the conventional APN network communication pattern and need set up special line; Construction and operation cost are higher; And be wired connection between data server and the commmunication company's GPRS network, in case fault such as broken string takes place, whole system maybe operate as normal etc. problem.
Description of drawings:
Fig. 1 forms sketch map for the utility model system.
Embodiment:
APN network system in a kind of power scheduling; It comprises monitoring station 1, control centre 2 and data server 3; Monitoring station 1 is connected to data transmit-receive antenna 4 with control centre 2 through GPRS wireless network 3, and data transmit-receive antenna 4 is connected to data server 6 through USB line 5.
Data transmit-receive antenna 4 is positioned at same room, 4 placements near the window of data transmit-receive antenna with data server 6.
All monitoring stations and control centre need professional to commmunication company's application APN private network in advance.Move to the client distributes special-purpose APN wireless network, domestic consumer must not apply for this APN.The SIM of a GPRS private network of each site configuration is only opened this special use APN, and other APN is used in restriction.Obtain distributing mobile internal fixation IP number for all monitoring stations and control centre behind the APN.After all websites power on, can directly initiate APN and connect to GPRS network.APN private network through under the GPRS network carries out data interaction; Data server is through the data transmit-receive antenna; Receive the APN private network data sent information under the GPRS network, under this communication mode, because control centre and monitoring station all are furnished with mobile Intranet fixed ip address; Cut down the number of intermediate links, stability strengthens; And all data are all moving the APN Intranet transmission of GPRS; Need not through public network, fail safe also is guaranteed, and has solved under the general networks communication mode and need set up special line; Construction and operation cost are higher; And be wired connection between data server and the commmunication company's GPRS network, in case fault such as broken string takes place, whole system maybe operate as normal etc. problem.
Claims (2)
