Description
Technical field
The present invention relates to a kind of train display, particularly a kind of redundant display of train operation monitoring device.
Background technology
LKJ2000 type train operation monitoring device is promoted the use of in system-wide as the primary watch-dog of domestic locomotive, in guarantee railway safety and the safety management of propelling engineering, played significant effect.TYX-I type screen display is man-machine interaction (DMI) equipment supporting with LKJ2000 type supervising device, mainly completes the display of human-computer dialogue and information.Dropped into since using, screen display shows intuitively with it, and good recognizes the property read, friendly human-computer interaction interface, at specification and the manipulative behavior correcting engine drivers in locomotive depot, prevents bad accident, guarantees that the aspects such as train operating safety play an important role.But the screen display of existing LKJ2000 type train operation monitoring device only has a display, when circuit goes wrong or software goes wrong, display all can be made normally to use, have a strong impact on the operation of train.
Utility model content
The problem that the utility model solves, for above-mentioned the deficiencies in the prior art, provides a kind of redundant display of train operation monitoring device, can, after main screen display fault, for train provides standby screen LCD display system for subsequent use, train normally be run.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A redundant display for train operation monitoring device, comprise main screen and standby screen, main screen comprises connected main screen processing unit and main screen expanding element,
Main screen processing unit comprises LCDs, and main screen expanding element comprises voice device, main screen button, main IC-card, and main screen button and main IC-card are used for input parameter in train operation monitoring device.
Standby screen comprises connected standby screen processing unit and standby screen expanding element.
Standby screen processing unit comprises standby screen button and liquid crystal display, standby screen expanding element comprises standby IC-card and voice device, the power supply of described main screen and standby screen, communication interface, governor circuit, button, voice device, IC-card are separate, and main screen is connected by the change-over switch between power supply with standby screen.
Described change-over switch is single-pole double-throw switch (SPDT).
Main screen is by main screen Power supply, and main screen power supply is the external power supply of train operation monitoring device; Standby screen is by standby screen Power supply, and standby screen power supply is standby screen internal independence power supply.
RS485 or the RS422 communication interface that main screen expanding element is connected with switching value and the road that communicates with the external world isolates, the CAN communication interface of two-way isolation.
Standby screen expanding element is connected with switching value and carries out with the external world CAN communication interface that communicates.
Compared with prior art, the utility model has following beneficial effect: the utility model is on original display basis, add a standby panel type display, simultaneously standby panel type display be two cover electrical isolation with main screen display, the system that is separated of circuit, only be connected with standby screen power supply by main screen power supply by change-over switch, therefore, no matter main screen is software is broken down or hardware failure, standby panel type display can be switched to fast, thus do not affect the normal operation of train.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the utility model embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1, the redundant display of a kind of train operation monitoring device that the utility model provides, comprise main screen and standby screen, main screen comprises connected main screen processing unit and main screen expanding element, main screen processing unit comprises LCDs, main screen expanding element comprises voice device, main screen button, main IC-card, and main screen button and main IC-card are used for input parameter in train operation monitoring device; RS485 or the RS422 communication interface that main screen expanding element is connected with switching value simultaneously and the road that communicates with the external world isolates, the CAN communication interface of two-way isolation; Standby screen comprises connected standby screen processing unit and standby screen expanding element, standby screen processing unit comprises standby screen button and liquid crystal display, standby screen expanding element comprises standby IC-card and voice device, and standby screen expanding element is connected with switching value simultaneously and carries out with the external world CAN communication interface that communicates.
Power supply, communication interface, governor circuit, button, voice device, the IC-card independence mutually of main screen and standby screen in the utility model, be connected by the change-over switch between power supply between main screen and standby screen, change-over switch is the single-pole double-throw switch (SPDT) of cold standby, when main screen breaks down, pass through single-pole double-throw switch (SPDT), be switched to standby screen power supply, will connect for screen, standby screen is by the communication between the standby screen of CAN communication Interface realization and main frame.
In certain embodiments, main screen display adopts the TFT high brightness chromatic liquid crystal screen of 10 inches, and standby liquid crystal display adopts the TFT high brightness chromatic liquid crystal screen of 3.5 inches, in host liquid crystal display fault situation, by manual switching to standby screen work; Meanwhile, in case of need, the screen size of display screen can be changed.
In specific works process, when main screen breaks down, shield the single-pole double-throw switch (SPDT) that power supply is connected by main screen with standby main screen power supply is disconnected, being switched to standby screen power supply, making to be energized for shielding.In the process, when main screen is energized, standby screen is in off-position, and main screen is communicated with outside by CAN communication interface, RS485 or RS422 communication interface; During standby screen energising, main screen is in off-position, and standby screen is communicated with LKJ main frame by CAN communication interface.Standby screen, as redundant display during main screen fault, has basic function and the basic operation of main screen.
Main screen power supply is the external power supply of train operation monitoring device, main screen power supply nominal voltage is 110V, if by battery as external power source, scope range of the fluctuation of voltage is within 0.7 ~ 1.25 times of nominal voltage, if by DC converter as external power source, scope range of the fluctuation of voltage is within 0.9 ~ 1.1 times of nominal voltage; Standby screen power supply is standby screen special inside power supply.
Described main screen also comprises an external 15V power supply, for connecting the change-over switch of main screen.
The main screen of redundant display and standby screen are also by the interface of special dump device as data input, output.
In the design of redundancy display screen, standby screen LCDs is less than main screen LCDs, as a kind of display screen for subsequent use when main screen fault, essential information display, setting, announcement inquiry, device status inquiries, keyboard detection, overhaul queries can be carried out, IC-card input, special driving, braking curve display.
