Description

The safety device of TV

Technical field

The utility model relates to a kind of TV safety device, particularly utilize the voice reminder user to keep correct viewing distance, and remind the rating time, and carry out the monitoring of temperature, electric current, voltage, thereby the accident of prevention Yin Wendu rising or wire short-circuiting, thunderbolt and the TV safety device of initiation fire.

Background technology

The popularizing of flourish and cable TV along with industry and commerce, it is relatively more quick and convenient to obtain information via TV, so TV has been amusement and recreation and the critical piping that in time obtains various information, becomes the indispensable electrical equipment commodity of every household.

Scientific and technological progress brings the TV user better seeing and hearing enjoyment, more powerful additional function also is provided, as: karaoke accompaniment function, PIP, recording playback shadow function ... .. or the like, yet it belongs to the functional increase of visual and sound effects mostly, bright rare to design relevant for TV safety and class hommization function, to such an extent as to cause the user because of the main cause of watching for a long time and viewing distance becomes myopia improperly.

In addition, when often having the user to watch TV because of the not good and sleeping example of mental status, it is not only the power consumption problem, severe patient will cause the overheated and danger of initiation fire of TV, though existing TV has been provided with the timed power on/off function, but most people and uncomfortable default rating time or be ignorant of operation and do not add utilization, therefore, the security functions of TV is necessary to strengthen.

Summary of the invention

Main purpose of the present utility model provides a kind of TV safety device that detects viewing distance that has, and utilizes infrared ray, thermoinduction or other similar device to realize detecting, and reminds the user to keep correct viewing distance thus in order to avoid affect one's power of vision and healthy.

Another purpose of the present utility model provides a kind of TV safety device with fire safety design, utilizes temperature control circuit monitoring TV internal temperature; Current/voltage overload detection circuit excessive current/voltage of monitoring moment cuts off electric installation thus, takes place with fire preventing.

Another purpose of the present utility model provides a kind of TV safety device with voice output.Voice output can make the TV of this utilization voice system technology have more the class hommization for reminding user's TV temperature anomaly, rating time overtime automatically and not keeping safe viewing distance etc.

Originally be to be achieved in that a kind of TV safety device, it is characterized in that comprising with novel above-mentioned purpose:

One central processing unit is connected with safe breaker device, counting device via bidirectional port, and is connected with voice device via one way ports, and connects range unit to receive distance measuring signal;

One safe breaker device, comprise automatic shutdown breaker device, and connected temperature control circuit and current/voltage overload detection circuit, described temperature control circuit connects Temperature Detector and receives the signal that is measured, and this current/voltage overload detection circuit detects excessive electric current, the voltage of moment of power supply;

One voice device, its input connects central processing unit and receives its output signal, and its output connects loud speaker;

One range unit is arranged at television headend, comprises the infrared facility, the heat induction device that connect central processing unit respectively;

One counting device connects central processing unit.

Originally be to be, utilize the voice reminder user to keep correct viewing distance, and remind the rating time, and carry out the monitoring of temperature, electric current, voltage with novel technique effect, thus the accident of prevention Yin Wendu rising or wire short-circuiting, thunderbolt and initiation fire.

Below in conjunction with accompanying drawing to originally being to be elaborated with novel.

Description of drawings

Fig. 1 is a structure block schematic diagram of the present utility model;

Fig. 2 is the schematic diagram that the utility model is arranged at TV;

Fig. 3 is that the utility model is in the embodiment of range unit schematic diagram.
