Description
Technical field
The utility model relates to technical field of television sets, is specifically related to a kind of television set of may command viewing distance.
Background technology
Along with the birth of TV with popularize, people's life ﹠ amusement custom has had very big variation.Each family almost, everyone sees TV every day.See that TV has become people's inseparable part of living, TV has also brought some harm to people when having enriched people's entertainment life, and particularly the healthy of people in the electromagnetic radiation serious threat.Although people have developed low radiation " environmental protection television " in recent years.Greatly reduce the healthy harm of electromagnetic radiation to people." environmental protection television " but of low radiation just reduced the radiation degree, and radiation hazradial bundle still exists.Add by the bad television habits of seeing of people's long-standing neglect, particularly closely, long-time TV reception, bring serious harm for the vision health of people's health, particularly youngsters and children.
Summary of the invention
The objective of the invention is, a kind of may command viewing distance is provided, the television set of vision protection and healthy a kind of may command viewing distance.
To achieve these goals, the technical solution of the utility model is: a kind of television set of may command viewing distance comprises television set, its design feature is: on the front casing of described television set lens are installed, the lens rear portion is equipped with transducer, sensor electrical is connected with overrun control, and overrun control is electrically connected with warning device.
Described transducer is a human body sensor.
Described transducer is a Thermoelectric Infrared Sensor.
Described warning device is a phonetic alarm device.
Described warning device is a flashing alarm device.
The utility model adopts technique scheme, on the front casing of television set lens is installed, and the lens rear portion is equipped with transducer, and sensor electrical is connected with overrun control, and overrun control is electrically connected with warning device.Transducer is made up of reflector, receiver, detection control circuit three parts.When human body or object enter preset distance; scioptics; Thermoelectric Infrared Sensor receives the human infrared signal that frequency is 0.1-8HZ; detecting control circuit can leach useful signal and use this signal; signal enters overrun control; overrun control picks up counting; in preset time; be left intact; greater than preset time; the control circuit relay is started working; make warning device work; input aerial by audio alert or control television set; suspend or brightness; contrast; color; sound circuit or standard state initialization circuit etc.; control to television set realizes warning function, and prompting spectators particularly youngsters and children have entered harmful distance.
Description of drawings
Accompanying drawing shows the structural representation of the utility model embodiment;
Embodiment
The utility model comprises television set 1, on the casing of the front of television set 1 lens 2 is installed, and lens 2 rear portions are equipped with Thermoelectric Infrared Sensor 3, and Thermoelectric Infrared Sensor 3 is electrically connected with delay controller 4, and delay controller 4 is electrically connected with warning device 5.Thermoelectric Infrared Sensor 4 is made up of reflector, receiver, detection control circuit three parts.When human body or object enter preset distance, scioptics 2, Thermoelectric Infrared Sensor 3 receives the human infrared signal that frequency is 0.1-8HZ, detecting control circuit can leach useful signal and use this signal, signal enters overrun control 4, overrun control 4 picks up counting, in preset time, be left intact, greater than preset time, the control circuit relay is started working, make warning device 5 work, input aerial by audio alert or control television set, suspend or brightness, contrast, color, sound circuit or standard state initialization circuit etc., to television set control, realize warning function, prompting spectators particularly youngsters and children have entered harmful distance; When human body withdrawed from the target setting scope, the control circuit relay was got back to reset condition, and audio alert stops or TV image recovers normal.
