Abstract
A heat radiation apparatus of a vehicle dual redundant display comprises a thermal conductive silicone layer arranged on the convex position of a display control module board, a back cover plate is covered on the thermal conductive silicone layer, and the back cover plate is provided with heat radiation strips. According to the technology scheme, a direct conduction heat radiation mode is employed, a housing is directly employed for heat radiation, heat generated by a CPU and a power supply is not centralized in a cabinet, and the system heat stability is enhanced.
Description
Technical field
The utility model relates to a kind of radiator on the display in the train operation monitoring device (LKJ) that is applied in.
Background technology
Train operation monitoring device (LKJ) is the important component part of Chinese train operation control system, is to be used to prevent that train overrun a signal, overspeed and donkey engine driver (containing the motor train unit driver) from improving the important traffic safety equipment of maneuvering capability.Vehicular display device is the important component part of train operation monitoring device (LKJ), it is the Man Machine Interface of direct and crew's exchange of information, mainly finish a function such as input, voice suggestion, audible and visual alarm of demonstration, the parameter of integrated informations such as figure, curve and related data, the reliability of Vehicular display device directly influences train operation monitoring device (LKJ) utilization, is the important leverage of traffic safety monitoring.
Along with the development of technology and improving constantly of requirement, the unfailing performance of Vehicular display device has been difficult to satisfy the requirement of on-the-spot utilization at present, mainly show: Vehicular display device adopts the single mode framework, under the situation that display breaks down, the driver influences normal driving because of not obtaining necessary running information; Part plate failure rate is higher, mainly shows aspects such as mainboard, connector, button; Vehicular display device becomes an important reasons that influences the normal utilization of train operation monitoring device (LKJ).
The utility model content
The purpose of this utility model is to provide a kind of and is applied on the vehicle-mounted pair of redundant display and the heat abstractor of good heat dissipation effect.
For achieving the above object, the utility model is by the following technical solutions:
A kind of heat abstractor of vehicle-mounted pair of redundant display, it comprises the heat-conducting silicone grease layer that is arranged on the display control module plate boss, back shroud is buckled on the heat-conducting silicone grease layer, and heat sink strip is set on the back shroud.
Described back shroud is provided with flange and cap, is hollow structure between flange and the cap; Wherein, flange is buckled on the heat-conducting silicone grease layer, and heat sink strip is set on the cap.
Adopt the utility model of technique scheme, adopt direct heat loss through conduction mode, directly use shell to dispel the heat, the heat that CPU and power supply are produced can not be collected in the cabinet, has improved the thermal stability of system.
Description of drawings
Fig. 1 is the rearview of the heat abstractor of vehicle-mounted pair of redundant display.
Fig. 2 is the radiator structure cutaway view of the heat abstractor of vehicle-mounted pair of redundant display.
Embodiment
Vehicle-mounted pair of redundant display mainly realized the human-computer interaction function of train operation monitoring device (LKJ), it is consistent with existing LKJ screen display that installation dimension keeps, on the basis of original screen display, set up alternate display, under main screen display fault situation, can keep locomotive by diverter switch manual switching to standby screen display and continue operation.Be specially: a kind of heat abstractor of vehicle-mounted pair of redundant display, it overlaps independently by two that display unit constitutes, and every cover display unit is respectively by separately power supply power supply; And all comprise control module and the driver module that is connected with control module, communication module, photoelectric isolation module, display screen and button in every cover display unit.
Wherein, power module is responsible for isolates conversion with locomotive 110V power supply, for each modular circuit of unit provides power supply; Driver module mainly provides loudspeaker, LCD backlight, ambient brightness is gathered, backlight and the control of liquid crystal display screen, the IC-card communicating circuit, circuit such as voice playing circuit, the keyboard input circuit is responsible for the scanning and the processing of driver's input keyboard, communication module is responsible for DMI and is isolated and conversion with communicating by letter of control unit or other external equipment, photoelectric isolation module is responsible for the isolation conversion of switching value signal, kernel control module is finished the work of treatment of all data, comprises literal and graphical display processing, keyboard operation is handled, CAN bus communication data processing, IC-card/usb data is handled, switching value input data processing, the read-write of IC-card/USB and data processing etc.
As shown in Figure 1, 2, the rear portion of vehicle-mounted pair of redundant display is provided with heat abstractor, and heat abstractor comprises the heat-conducting silicone grease layer 16 that is arranged on control module plate 15 boss, and back shroud 17 is buckled on the heat-conducting silicone grease layer 16, and on the back shroud 17 heat sink strip 18 is set.
Above-mentioned back shroud 17 is provided with flange 19 and cap 20, is hollow structure between flange 19 and the cap 20; Wherein, flange 19 is buckled on the heat-conducting silicone grease layer 16, and heat sink strip 19 is set on the cap 20.
