Abstract
The utility model relates to a set top box. The set top box comprises a CPU (central processing unit) main control module, an audio/video decoding module and an electromagnetic radiation detecting module, and a warning module, wherein both the audio/video decoding module and the electromagnetic radiation detecting module are connected with the CPU main control module. The electromagnetic radiating detecting module comprises an electromagnetic radiation sensor, a filter circuit, an amplifying circuit and an AD switching circuit which are sequentially connected. The AD switching circuit is connected with the CPU main control module. The set top box can be used for detecting electromagnetic radiation condition in a house at anytime and anywhere. When radiation exceeds, the set top box can warn users timely, so that the users can take protective measures conveniently. The set top box is convenient and reliable.
Description
Technical field
The utility model relates to set-top box functionality and expands the field.
Background technology
Along with the development of growth in the living standard, electronic technology, various electronic equipments are flooded with each family, comprise computer, television set, refrigerator, air-conditioning, mobile phone, microwave oven etc.During these electronic device works, all can produce the electromagnetic wave of various different wave lengths and frequency, family's electromagnetic radiation pollution has become a very important problem.Colourless, tasteless due to electromagnetic radiation, cannot see, can not touch, people can't perceive this stealthy the pollution by sense organ, so people pay close attention to more to the harm of environmental radiation, urgent wishing a kind ofly can remind people whether to be in equipment in electromagnetic radiation environment at any time, thereby provides safeguard procedures for the user.
Summary of the invention
The problem that the utility model need solve is to provide a kind of set-top box with electromagnet radiation detection function.
The technical solution adopted in the utility model is: a kind of set-top box, comprise the CPU main control module and be connected the audio/video decoding module with the CPU main control module, it is characterized in that, also comprise electro-magnetic radiation detection modules, described electro-magnetic radiation detection modules comprises electromagnetic radiation sensor, filter circuit, amplifying circuit, the A/D convertor circuit that connects successively, and described A/D convertor circuit is connected with the CPU main control module.
Preferably, described set-top box also comprises the alarm module that is connected with the CPU main control module.
The beneficial effects of the utility model are: described set-top box can detect the electromagnetic radiation situation in family whenever and wherever possible, and timely warning reminding user when radiation exceeds standard facilitates the user to take safeguard measure, and is convenient and reliable.
Description of drawings
Fig. 1 is that set-top box described in the utility model forms the structural representation block diagram.
Embodiment
Understand technology contents of the present utility model for convenience of those skilled in the art, below in conjunction with drawings and Examples, the utility model is described in further detail.
Set-top box that the utility model discloses, as shown in Figure 1, comprise that the CPU main control module reaches basic function module such as being connected the audio/video decoding module with the CPU main control module, also comprise electro-magnetic radiation detection modules, described electro-magnetic radiation detection modules comprises electromagnetic radiation sensor, filter circuit, amplifying circuit, the A/D convertor circuit that connects successively, described A/D convertor circuit is connected with the CPU main control module, and what be connected with the CPU main control module also has alarm as alarm module.control program is implanted in the chip of CPU main control module, control A/D convertor circuit by CPU, because the signal frequency range that sensing probe records is very wide, therefore, must there be filter circuit to carry out filtering to the pop one's head in signal of gained of electromagnetic sensing, and just faint electromagnetic signal is delivered to amplifying circuit, amplifying circuit amplifies faint electromagnetic signal and is sent to A/D convertor circuit, analog signal conversion becomes digital signal, digital signal after conversion is delivered to the CPU main control module again and is processed, the normal range (NR) that electromagnetic radiation is set by software must not be over the national standard limits value of 0.4W/ ㎡, when the value of electromagnetic radiation meets or exceeds the scope of setting, the driving alarm gives the alarm.
Above-described embodiment is only wherein specific implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection range of the present utility model.
