Description
Technical field
The utility model relates to a kind of prior-warning device, particularly uses the family expenses early warning collision avoidance system of infrared acquisition identification, belongs to the detection alarm technical field.
Background technology
In daily life staying idle at home, the switch door is the most usual thing, but crude and rash firmly opening the door causes the people behind the door and the people's that opens the door unexpected injury easily, and especially domesticated animal is caused injures and deaths more easily in the family because meeting owner.Because blocking of door is difficult to discover situation behind the door when opening the door, arbitrary decision does not habitually have the human or animal behind the door easily, and irritable with barbarous opening the door causes beyond thought injury more easily, brings hidden danger to daily life.Therefore, having to provide a kind of early warning collision avoidance system that opens the door, and reduces the generation of this type of incident as far as possible.
Summary of the invention
Blocking because of door when opening the door in the life staying idle at home in order to solve; And whether identification in time has the human or animal to cause the problem of unexpected injury behind the door; The utility model provides a kind of prior-warning device; This device can be the human or animal near in the square detection range behind the door the time, and the people who prepares to open the door to opposite side sends early warning, the accident that causes with the collision that prevents to open the door.
The utility model adopts following technical proposal to accomplish: family expenses open the door the early warning collision avoidance system by infrared sensor I 3 in LED light 1, single-chip microcomputer 2, the door, loudspeaker 4 and outdoors infrared sensor II 5 form; Single-chip microcomputer 2 is connected with the interior infrared sensor I 3 of door through I/O mouth P0, is connected with infrared sensor II 5 outdoors through I/O mouth P1, is connected with LED light 1 through I/O mouth P2, is connected with loudspeaker 4 through I/O mouth P3.
Infrared sensor I 3 can be fixed on the vertical direction of an inboard detection range in the described door; Infrared sensor II 5 is fixed on outer side of door detection range vertical direction outdoors; LED light 1 is fixed on outdoors with loudspeaker 4; Single-chip microcomputer 2 is placed on behind the door, and LED light 1, loudspeaker 4, infrared sensor II 5 is connected with single-chip microcomputer 2 through data line through hole in door outdoors.
Infrared sensor I 3 in described LED light 1, single-chip microcomputer 2, the door, loudspeaker 4 and outdoors infrared sensor II 5 be commercially available common components.
The principle of work of the utility model: after the device installation; Infrared sensor I 3 signals are gathered in real time in single-chip microcomputer 2 opposite houses; Single-chip microcomputer 2 is made the judgement whether human or animal is arranged through information processing; And the result stored with the mode of state value, single-chip microcomputer 2 will show for LED light 1 and make judgement according to this state value send state information, remind the people that opens the door that the human or animal is arranged behind the door; Avoid causing human or animal's behind the opposite house injury, with this crashproof purpose of early warning that realizes opening the door.
The beneficial effect of the utility model is, can make identification through infrared sensor acquired signal relief single-chip microcomputer, reminds the people that opens the door that the human or animal is arranged behind the door through LED light; When the people that opens the door attempts to proceed to open the door; Utilize loudspeaker to make further early warning, to prevent that device is installed simple and easy because of the day unexpected injury that brings of hold-open door; Function is practical, and is easy to utilize.
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model.
Among the figure: the 1-LED pilot lamp, infrared sensor I in the 2-single-chip microcomputer, 3-door, 4-loudspeaker, 5-be the infrared sensor II outdoors.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified, understand to make things convenient for the technician.
As shown in Figure 1: family expenses open the door the early warning collision avoidance system by infrared sensor I 3 in LED light 1, single-chip microcomputer 2, the door, loudspeaker 4 and outdoors infrared sensor II 5 form; Single-chip microcomputer 2 is connected with the interior infrared sensor I 3 of door through I/O mouth P0, is connected with infrared sensor II 5 outdoors through I/O mouth P1, is connected with LED light 1 through I/O mouth P2, is connected with loudspeaker 4 through I/O mouth P3.
Infrared sensor I 3 can be fixed on the vertical direction of an inboard detection range in the door; Infrared sensor II 5 is fixed on outer side of door detection range vertical direction outdoors; LED light 1 is fixed on outdoors with loudspeaker 4; Single-chip microcomputer 2 is placed on behind the door, and LED light 1, loudspeaker 4, infrared sensor II 5 is connected with single-chip microcomputer 2 through data line through hole in door outdoors.
After the device installation; Infrared sensor I 3 signals are gathered in real time in single-chip microcomputer 2 opposite houses; Whether the signal that collects there is human or animal's identification, and the result ' is had ' with state value or the two-value mode of ' nothing ' is stored, according to this state value; If state value carries out the early warning demonstration for ' having ' then opened LED light 1, ' nothing ' then closed LED light 1.
When someone outdoors gets into the safe early warning distance; Infrared sensor II 5 is sent signal with the mode of interrupting and is given single-chip microcomputer 2 outdoors; Single-chip microcomputer 2, is then opened loudspeaker 4 and is carried out phonetic warning if value is ' having ' according to situation is judged the value of store status that obtains; The behavior that further stops the people that opens the door to ignore LED light 1 early warning information and carry out continues the injury that causes to avoid door knob to hit.
The utility model describes through the practical implementation process; Under the situation that does not break away from the utility model scope; Can also carry out various conversion and be equal to replacement utility model; Therefore, the utility model is not limited to disclosed practical implementation process, and should comprise the whole embodiments that fall in the utility model claim scope.
