Abstract
The utility model discloses a photoelectric direct-reading type intelligent gas meter which comprises a base meter and a coding plate (1). A main plate (2) is arranged on the base meter, a lighting tube (1-1) and a receiving tube (1-2) are arranged on the coding plate (1), the lighting angle of the lighting tube (1-1) is smaller than or equal to 30 degrees, and the coding plate (1) is welded on the main plate (2) through a pin (3). The meter is strong in anti-jamming performance and good in mechanical connection strength and reduces manufacture cost.
Description
Technical field
The utility model relates to a kind of photoelectric direct-reading intelligent gas meter.
Background technology
At present; The luminotron of the photo-electronic directly reading table under the prior art uses big lighting angle (lighting angle is 120 °) paster encapsulating light emitting pipe, and infrared or visible light form is too easily by external interference; Poor anti jamming capability; The producer that has also need increase darkening ring, and the production difficulty is big, and cost also can increase.Encoding board is connected with mainboard with the mode of similar golden finger, causes failure welding phenomenon and connection physical strength little easily, the shortcoming that production efficiency is low.
Summary of the invention
The purpose of the utility model is the defective that overcomes prior art, and a kind of strong interference immunity, photoelectric direct-reading intelligent gas meter that mechanical connection intensity is good are provided.
The technical scheme that realizes the utility model purpose is: a kind of photoelectric direct-reading intelligent gas meter; It comprises base table and encoding board, has mainboard on the base table, and encoding board is provided with luminotron and receiving tube; The lighting angle of described luminotron≤30 °, encoding board is welded on the mainboard through row's pin..
After having adopted technique scheme, the luminotron lighting angle that the utility model adopts is less, and encircled energy is high, and has good directive property; Be not easy by external interference, antijamming capability is strong, so just makes receiving tube acceptant to signal; Also do not need darkening ring, provide cost savings, the utility model uses row's pin that encoding board is welded on the mainboard; Row's pin is an one-piece construction, and technological operation property is strong, and mechanical connection intensity is good.
Description of drawings
Fig. 1 is the encoding board of the utility model and the synoptic diagram that is connected of mainboard;
Fig. 2 is the left view of Fig. 2;
Fig. 3 is the scheme of installation on the encoding board of the utility model.
Embodiment
For the content that makes the utility model is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation,
Shown in Fig. 1 ~ 3, a kind of photoelectric direct-reading intelligent gas meter, it comprises base table and encoding board 1; Has mainboard 2 on the base table; Encoding board 1 is provided with luminotron 1-1 and receiving tube 1-2, the lighting angle of described luminotron 1-1≤30 °, and encoding board 1 is welded on the mainboard 2 through row's pin 3.
The principle of work of utility model is following:
The luminotron 1-1 lighting angle that the utility model adopts is less, and encircled energy is high, and has good directive property; Be not easy by external interference, antijamming capability is strong, so just makes receiving tube 1-2 acceptant to signal; Also do not need darkening ring, provide cost savings, the utility model uses row's pin 3 that encoding board 1 is welded on the mainboard 2; Row's pin 3 is one-piece constructions, and technological operation property is strong, and mechanical connection intensity is good.
The single-chip microcomputer internal processor is selected in information processing for use, and base table receives signal, and luminotron 1-1 and receiving tube 1-2 start working, and produces 30 parallactic angle degree coded systems, gets access to the real data of current indication, and gives upper system data transmission, realizes meter-reading function.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (1)
