Abstract
The utility model provides a smoke induction automatic protection system for TV set and the TV set, suitable for a television field. The system comprises a CPU of a TV set, and also comprises: a gas sensor for detecting smoke signal of the TV set and conversing the detected smoke signal into magnitude of voltage and then outputting, wherein the gas sensor is connected with the CUP of the TV set; a comparative module connected with the CUP for comparing the magnitude of voltage output by the gas sensor with preset normal voltage magnitude; a power cut-off control module connected with the CPU of the TV set for cutting off the power of the TV set when the output magnitude of voltage of the gas sensor exceeds a preset normal voltage value range. The system of the utility model can prevent the TV set from firing.
Description
Technical field
The utility model belongs to TV domain, relates in particular to a kind of television set sense smog system and the television set of protection automatically.
Background technology
Television set can be owing to its internal body temperature too high or other reasons cause some interior components and parts of television body phenomenon of smoldering of catching fire.Though the television set of Xiao Shouing has been done some safeguard measures to the abnormal condition of television set aspect a lot of in the market; but these measures much can only prevent some components and parts of television set self and not be damaged, and can't avoid the generation of incidents such as " baked wheaten cake machines ".
The utility model content
The utility model embodiment technical problem to be solved is to provide a kind of system and television set that can prevent the automatic protection of television set sense smog that television set catches fire.
For solving the problems of the technologies described above, the utility model embodiment provides a kind of television set sense smog system of protection automatically, comprises the CPU of television set; Described system also comprises:
Be used to detect the smoke signal of television set, and convert described detected smoke signal to gas sensor that magnitude of voltage is exported, described gas sensor is connected with the CPU of described television set;
The comparison module that being used for of being connected with the CPU of described television set compares the magnitude of voltage of described gas sensor output and default normal voltage value;
Be connected with the CPU of described television set be used for magnitude of voltage when gas sensor output and exceed described default normal voltage value scope the time, then cut off the control module of cutting off the electricity supply of the power supply of television set.
The utility model embodiment also provides a kind of television set sense smog recited above television set of the system of protection automatically that comprises.
In the utility model embodiment, can detect the smoke signal of television set by gas sensor, when television set causes in the body some components and parts to catch fire smoldering phenomenon for some reason, this gas sensor can detect and export the CPU that an abnormal voltage is given television set, when this voltage exceeds the normal voltage scope that presets, with the dump of television set; Thereby reach the effect that can prevent that television set from catching fire.
Description of drawings
Fig. 1 is the television set sense smog that provides of the utility model embodiment structural representation of the system of protection automatically.
Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
In the utility model embodiment, at the inner gas sensor of installing of television set, the output interface of this gas sensor is connected with the AD interface of the CPU of television set, thereby the output signal of gas sensor can be transferred on the AD interface of CPU of television set; When having smog to occur in the television body, the magnitude of voltage of this gas sensor output is under the normal condition different with television set.
See also Fig. 1, be the automatic system that protects of television set sense smog that the utility model embodiment provides, this system mainly comprises: gas sensor 10, CPU20, comparison module 30 and the control module 40 of cutting off the electricity supply.The described television set sense smog system of protection automatically can be built in the television set.
This gas sensor 10 detects the smoke signal of television set, and converts described detected smoke signal to CPU20 that magnitude of voltage is exported to television set; Comparison module 30 compares the magnitude of voltage of described gas sensor 10 outputs and default normal voltage value, if when exceeding described default normal voltage value scope, the control module of then cutting off the electricity supply 40 is cut off the power supply of television sets.
For example: behind the television boot-strap, gas sensor detects the smoke signal of television set, and converts described detected smoke signal to magnitude of voltage and export on the AD interface of CPU of television set; Detect in real time the magnitude of voltage on the AD interface of CPU that gas sensor outputs to television set; When television set is under the normal condition; the voltage of gas sensor output is stable and in an effective range; when some components and parts in the television body catch fire or other is former thereby when producing the smog phenomenon; then this gas sensor can be sensed the also magnitude of voltage of output abnormality voltage; preset a normal voltage value scope in advance; when the magnitude of voltage of this gas sensor output has exceeded the normal voltage value scope that presets; then automatic dump with television set; make television set enter the smog guard mode, thereby reach the effect that can prevent that television set from catching fire.
As from the foregoing, the utility model embodiment can detect the smoke signal of television set by gas sensor, when television set causes in the body some components and parts to catch fire smoldering phenomenon for some reason, this gas sensor can detect and export the CPU that an abnormal voltage is given television set, when this voltage exceeds the normal voltage scope that presets, with the dump of television set; Thereby reach the effect that can prevent that television set from catching fire.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
