Abstract
The utility model relates to an infrared probe capable of resisting the interference of the sun, relating to the technical fields of infrared reception and infrared transmission. The utility model comprises a housing, a filter eyeglass, an infrared transmitting pipe, an infrared receiving pipe, and a separating and stopping piece, wherein, the filter eyeglass is arranged on the top of the housing, and the infrared transmitting pipe and the infrared receiving pipe are arranged on the bottom of the housing; the separating and stopping piece is arranged between the infrared transmitting pipe and the infrared receiving pipe; a hollow cavity which is contained between the top of the housing and the bottom of the housing is a table-shaped hollow cavity, and the top of the area of the cross section of the table-shaped hollow cavity is larger than the bottom of the area of the cross section of the table-shaped hollow cavity; the lateral surface of the table-shaped hollow cavity is a rough surface. The utility model better avoids the interference of the sunlight, and the distance of the infrared transmission can reach six meters in the sun and can reach fifteen meters in a room. The utility model which effectively increases the distance of data information which is transmitted by infrared rays has the advantages of simple structure, easy process, and easy production.
Description
The utility model relates to infrared receiving data information technical field.
In the data collector of infrared transmission media, when especially existing infrared palmtop PC (also claiming infrared write by hand machine) carries out infrared-ray communication to three-phase electric energy meter, single-phase electric energy meter, electric quantity data acquisition device or other electronic instrument equipment etc., because the infrared ray launches and receives pipe at two ends only uses Red lightscreening plate to make face shield, interference does not all have special effective technology measure to sunlight, so transmission range is all very limited, especially outdoor than the strong sunlight condition under, general transmission range does not reach actual requirement less than about one meter at all.
The purpose of this utility model is to avoid above-mentioned weak point and provides that a kind of anti-sunlight disturbs, simple in structure, infrared receiving transducer that transmission range is far away.
The purpose of this utility model can realize like this: design the infrared probe that a kind of anti-sunlight disturbs, comprise housing, be positioned at the retaining piece between the filter glass of case top, the infrared emission tube that places housing bottom and infrared receiver tube and infrared tube, the cavity that contains between case top, the bottom is a platform shape cavity, the cross-sectional area top of platform shape cavity is greater than the bottom, and the side surface of platform shape cavity is a rough surface.
The utility model has been avoided the interference of sunlight preferably, makes infrared transmission distance can reach 6 meters in the sun, indoorly reaches 15 meters, has improved the distance of infrared transmission information effectively.The utility model is simple in structure, easily processing and fabricating.
Description of drawings:
Fig. 1 is the profile of the utility model most preferred embodiment;
Fig. 2 is the part sectioned view of a kind of structure of Fig. 1;
Fig. 3 is the AB profile of one of the utility model most preferred embodiment.
Fig. 4 is two an AB profile of the utility model most preferred embodiment.
Fig. 5 is the part sectioned view of the another kind of structure of Fig. 1.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, the infrared probe that a kind of anti-sunlight disturbs, comprise housing 1, be positioned at the retaining piece 5 of 3,4 of the filter glass 2 at housing 1 top, the infrared emission tube 3 that places housing 1 bottom and infrared receiver tube 4 and infrared tubes, the cavity that contains between housing 1 top, the bottom is a platform shape cavity 6, and the cross-sectional area top of platform shape cavity is greater than the bottom; As shown in Figure 2, platform shape cavity 6 is a garden platform shape; As shown in Figure 3, the side surface of platform shape cavity (6a) is a step-like surface; The color of the side surface 6a of platform shape cavity is dark.Eyeglass 2 is the red filter sheet in the present embodiment, and dark step-like surface is the black step-like surface; Base 7 is used for fixing infrared ray pipe fitting plate.The light close with infrared ray is reflected when sunlight is mapped on the ladder through red filter 2, have only and gather into a branch of infrared ray and just can be mapped on the infrared receiver tube 4 and received by circuit, avoided the interference of sunlight like this, the infrared transmission distance can be improved effectively.
As Fig. 1,, shown in, the infrared probe that a kind of anti-sunlight disturbs, comprise housing 1, be positioned at the retaining piece 5 of 3,4 of the red filter sheet 2 at housing 1 top, the infrared emission tube 3 that places housing 1 bottom and infrared receiver tube 4 and infrared tubes, the cavity that contains between housing 1 top, the bottom is a platform shape cavity 6, and the cross-sectional area top of platform shape cavity is greater than the bottom; As shown in Figure 4, platform shape cavity 6 is the terrace with edge shape; As shown in Figure 5, the side surface 6a of platform shape cavity is a hackly surface; The color of platform shape cavity side surface 6a is a black.Terrace with edge can be many ribs, as triangular, four ribs, five ribs, six ribs etc.Equally, the light close with infrared ray is reflected when sunlight is mapped on the sawtooth through red filter 2, have only and gather into a branch of infrared ray and just can be mapped on the infrared receiver tube 4 and received, avoided the interference of sunlight like this, the infrared transmission distance can be improved effectively by circuit.
