Abstract
The utility model discloses a static data exchange device, solving the problem so that an internal network and an external network are effectively isolated while exchanging information in a safe, convenient and timely manner. The static data exchange device comprises a terminal management computer (1), a static data exchanger (2), an external network server (8) and an internal network server (9). A first data memory (3), a second data memory (4) and a polarized relay (7) are arranged in the static data exchanger (2). The terminal management computer (1) is electrically connected with the first data memory (3) and the second data memory (4), respectively. The first data memory (3) and a second port of the polarized relay (7) are electrically connected via a 485 control line (5), and the second data memory (4) and a third port of the polarized relay (7) are electrically connected via a first USB bus protocol data line (6). The static data exchange device of the utility model is mainly used for automatic static data exchange between two physically-isolated networks, saving the manual copying operation.
Description
Technical field
The utility model relates to a kind of static data switching equipment of physical isolation two nets.
Background technology
Between the work operation control and management net and outer net of electric power system; Often to carry out exchanges data; Because the work of electric power system operation control and management net relates to the normal operation of electric power system; Its fail safe is important especially, but the exchanges data of Intranet and outer net is again necessary sometimes, so the on-the-spot convenient again xegregating unit that exchanges with outer net timely of a kind of safety that promptly guarantees Intranet of being badly in need of.
Summary of the invention
The utility model provides a kind of static data switching equipment, has solved that Intranet and outer net can effectively be isolated and can safe ready have carried out the difficult problem of exchange message timely.
The utility model overcomes the above problems through following scheme:
A kind of static data switching equipment; Comprise terminal management computer, static data interchanger, outer network server and interior network server; In the static data interchanger, be provided with first data storage, second data storage and polarized relay; The terminal management computer is electrically connected with first data storage and second data storage respectively; First data storage is electrically connected through 485 control lines with the second choosing mouth of polarized relay; Second data storage is electrically connected through the first usb bus protocol data line with the 3rd choosing mouth of polarized relay, and the first choosing mouth that the USB mouth of outer network server passes through the second usb bus protocol data line and polarized relay is electrically connected, and the USB mouth of interior network server selects mouth to be electrically connected through the 4th of the 3rd usb bus protocol data line and polarized relay.
Directly be electrically connected through USB interface between first data storage and second data storage.
The static data that the utility model is mainly used between physical isolation two nets exchanges automatically, has saved the manpower work of duplicate copy.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Specific embodiment
A kind of static data switching equipment; Comprise terminal management computer 1, static data interchanger 2, outer network server 8 and interior network server 9; In static data interchanger 2, be provided with first data storage 3, second data storage 4 and polarized relay 7; Terminal management computer 1 is electrically connected with first data storage 3 and second data storage 4 respectively; First data storage 3 is electrically connected through 485 control lines 5 with the second choosing mouth of polarized relay 7; Second data storage 4 is electrically connected through the first usb bus protocol data line 6 with the 3rd choosing mouth of polarized relay 7, and the first choosing mouth that the USB mouth of outer network server 8 passes through the second usb bus protocol data line 10 and polarized relay 7 is electrically connected, and the USB mouth of interior network server 9 selects mouth to be electrically connected through the 4th of the 3rd usb bus protocol data line 11 and polarized relay 7.
Directly be electrically connected through USB interface between first data storage 3 and second data storage 4.
The utility model is through polarized relay, and the USB mouth of two-server is coupled together, and shares a USB device at interval.Through being installed in the timing adjustment program on the server, can realize the copy of static data, the safe and timing deletion of USB flash disk hardware, the mode control appliance circuit through the USB virtual serial port switches simultaneously, is connected on the other station server.Automatically the automatic playing function of forbidding USB flash disk is stopped USB flash disk virus and between server, is propagated.
Claims (2)
1. static data switching equipment; Comprise terminal management computer (1), static data interchanger (2), outer network server (8) and interior network server (9); It is characterized in that; In static data interchanger (2), be provided with first data storage (3), second data storage (4) and polarized relay (7); Terminal management computer (1) is electrically connected with first data storage (3) and second data storage (4) respectively; First data storage (3) is electrically connected through 485 control lines (5) with the second choosing mouth of polarized relay (7); Second data storage (4) is electrically connected through the first usb bus protocol data line (6) with the 3rd choosing mouth of polarized relay (7); The first choosing mouth that the USB mouth of outer network server (8) passes through the second usb bus protocol data line (10) and polarized relay (7) is electrically connected, and the USB mouth of interior network server (9) is electrically connected through the 4th choosing mouth of the 3rd usb bus protocol data line (11) and polarized relay (7).
