Abstract
The utility model relates to the technology of heat radiation of systems, and provides an outdoor display device for preventing the unusual increase of internal heat. The outdoor display device comprises a box body, a crystal liquid flat television, a power supply module, a fan, a temperature sensor, a command processing module; wherein, the fan is arranged on the wall of the box body; the crystal liquid flat television, the temperature sensor and the command processing module are arranged in the box body; the fan is connected with the output end of the command processing module; the temperature sensor is connected with the input end of the command processing module; the power supply module is respectively connected with the fan, the command processing module and the temperature sensor. The outdoor display device can timely detect the temperature in the box body, forcedly dispels the heat to achieve the effect of reducing the temperature of the crystal liquid flat television without influencing on the normal work of the whole television, avoids the unusual situation of the whole television, improves the reliability of the whole television, and prolongs the service life of the whole television.
Description
Technical field
The utility model relates to the system radiating technology.
Background technology
The liquid crystal flat-panel TV has characteristics such as complete machine is in light weight, thin thickness, suitable wall hanging.Based on the characteristics of the suitable wall hanging of liquid crystal flat-panel TV, can be widely used in outdoor advertising, information demonstration place (train number, Flight Information as station, harbour, airport show, corporate advertising issue, Weather information forecast etc.).When the liquid crystal flat-panel TV is used for the open air because consider to make moist, factor such as rainproof, dustproof causes the system failure, usually the liquid crystal flat-panel TV is installed in the casing that relatively seals.In the casing of relatively sealing, the system thermal of liquid crystal flat-panel TV is difficult for distributing.When summer, ambient temperature reached 45 ℃ of left and right sides; may cause that temperature reaches more than 80 ℃ in the casing; thereby the reliability that the system of influence works long hours; unusual or the LCDs damage of power protection, signal processing circuit operating state can appear; complete machine occurring can't start or system's out-of-control phenomenon such as image, cacophonia; complete machine will be in the abnormal work state always, cause the lifetime of system minimizing when serious or cause the fault expanded range.
The utility model content
Technical problem to be solved in the utility model provides a kind of unusual outdoor displaying device that increases of internal heat that prevents.
The technical scheme that the utility model adopted is that outdoor displaying device comprises casing, liquid crystal flat-panel TV, supply module, fan, temperature sensor, command processing module; Fan is arranged on the box body wall, liquid crystal flat-panel TV, temperature sensor and command processing module are arranged in the casing, fan links to each other with the output of command processing module, temperature sensor links to each other with the command processing module input, and described supply module links to each other with fan, command processing module, temperature sensor respectively.
Described command processing module is a liquid crystal flat-panel TV internal processor.Liquid crystal flat-panel TV internal processor links to each other with fan, temperature sensor respectively by system bus.
The beneficial effects of the utility model are, can detect the temperature in the casing in real time, and carry out the heat forced discharge, reach the effect that reduces liquid crystal flat-panel TV temperature, do not influence the operate as normal of complete machine, avoid complete machine to enter abnormality, improved the reliability of complete machine, prolonged the useful life of complete machine.
Description of drawings
Fig. 1 is the Circuits System block diagram of outdoor displaying device.
Embodiment
In the casing of the relatively sealing that the liquid crystal flat-panel TV is installed, temperature sensor is installed, fan is installed in box body wall.Temperature sensor places box house, when sensor (generally can be set at 60 ℃) when the box house temperature is higher than preset value, transmit control signal and give the GPIO port of command processing module, by another GPIO port controlling starting fan of command processing module.When temperature was lower than set point in the casing, transducer transmitted the GPIO port that control signal is given command processing module, and another GPIO port controlling fan by command processing module stops.Outdoor displaying device comprises casing, liquid crystal flat-panel TV, supply module, fan, temperature sensor, command processing module; Circuit connects as shown in Figure 1, and fan links to each other with the output of command processing module, and temperature sensor links to each other with the command processing module input, and described supply module links to each other with fan, command processing module, temperature sensor respectively.
Wherein, command processing module can be a liquid crystal flat-panel TV internal processor, also can be independently.Command processing module, fan and temperature sensor can also be the circuit module of one.
