Abstract
Disclosed is a direct beam double phototube sensor, which solves the strong external interference to the sensor but not the water meter inversion count. The utility model comprises an annular sensor fixed ring and a sensor circuit. Wherein, two photocells are arranged on the circumference side wall of the annular sensor fixing ring through mounting holes. The emission rays of the two phototubes intercross. Two brackets on the sensor fixing ring extend inside, which is on the extended line of emission rays of the two photocells. A photoelectric receiving tube, a photocell and a secondary instrument of receiving tube connected through sensor circuit are respectively arranged on a bracket end at the other side of indication circumference. The novel sensor does not change the original meter structure and overcomes the shortcoming of the existing sensors, which is basically not disturbed by external interference and solves successfully the problems by water meter reverse rotation. The design of structure is unique and creative with a sealing performance reaching IP 68 sealing grade.
Description
[technical field]: the utility model relates to the sensor that uses in a kind of water resource measurement and control area, particularly tap water kilowatt meter reading-out system.
[background technology]: the existing sensor that is applied to tap water kilowatt meter reading-out system (as water meter etc.) mostly is dry reed tube formula or reflection light barrier type, and this sensor is subjected to external interference big, and can not solve water meter reversing problem.
[summary of the invention]: this novel purpose is to solve existing sensor to be subjected to external interference big, can not solve water meter reversing enumeration problem, and a kind of direct-injection type two photoelectric tube sensor is provided.
The utility model direct-injection type two photoelectric tube sensor, comprise loop sensor set collar, sensing circuit, it is characterized in that on the circumferential side wall of loop sensor set collar, two photoemission cells being installed by mounting hole, the emission light of two photoemission cells intersects mutually, two supports on the sensor set collar inwardly stretch out, its on the emission light extended line of two power valves and the bracket end that is positioned at indicating value circumference opposite side a photoelectric receiving tube respectively is installed, power valve is connected secondary instrument with receiving tube through sensing circuit.
Sensing circuit comprises two photoemission cell, two photoelectric receiving tubes as photoelectric signal collection as photosignal output, the shading wheel location judges that CPU sends electric signal into photoemission cell through the coded modulation circuit, photoelectric receiving tube receives according to it or does not receive that photosignal produces a low or high level, and this electric signal sent back to after the shading wheel location judges CPU by the demodulation output circuit, send into secondary instrument.
The emission light extended line of two photoemission cells lays respectively at the both sides in the center of circle of the indicating value circumference that will extract flow signal.
Advantage of the present utility model and effect: 1, this novel sensor does not change original table body structure, is to design for the defective that solves moment sensor, is not subjected to extraneous interference substantially, and successful solution reverse the problem of being brought by water meter.Structural design has uniqueness, novelty, and sealing property has reached IP68 sealing grade.

[embodiment]:
As shown in Figure 1, 2, this direct-injection type two photoelectric tube sensor, comprise loop sensor set collar 1, on the circumferential side wall of this set collar, two photoemission cells 2,3 are installed by mounting hole, the emission light of two photoemission cells intersects mutually, and lays respectively at the both sides in the center of circle of the indicating value circumference on the water meter digital disk 4 that will extract flow signal.Two receiving tube supports 5 on the sensor set collar inwardly stretch out, its on the emission light extended line of two power valves and the bracket end that is positioned at indicating value circumference opposite side a photoelectric receiving tube 6,7 respectively is installed, power valve is connected secondary instrument with receiving tube through sensing circuit.
The sensing circuit (see figure 3), comprise two photoemission cell, two photoelectric receiving tubes as photoelectric signal collection as photosignal output, the shading wheel location judges that CPU sends electric signal into photoemission cell through the coded modulation circuit, whether photoelectric receiving tube receives that according to it photosignal produces a low or high level, and this electric signal sent back to after the shading wheel location judges CPU by the demodulation output circuit, send into secondary instrument.Concrete connecting circuit is referring to Fig. 5.
Wherein, photosignal output, collecting work Principle of Process are seen Fig. 4, and when centre wheel blocked dish or pointer 8 and is in position I, it blocked aa ' light, and a ' is closed, and produces a high level; A ' and b ' all can receive the light that a, b send when being in the II position, and a ', b ' all produce a low level; In like manner, when being in the III position, b ' closes, and produces a high level, and when being in the IV position, a ', b ' all are blocked, and then respectively produce a high level.When centre wheel rotated a week, the order of its output signal was:
b’------00------a’------a’b’-------b’
When counter-rotating, the order of its output signal is:
a’------00------b’------a’b’-------a’
Because sampled signal is one group of signal, and the order of two kinds of signals is antipodal, therefore just can differentiate the rotating of water meter.
This sensor can be installed on any indicating value pointer position by the pilot hole on the set collar 9, as: on 0.001,0.01,0.1,1 tonnage such as grade, see Fig. 1.Suitably adjust the position of two receiving tube supports 5 and the angle of mounting hole, or change the diameter of set collar, this sensor goes for the indicating value pointer of different sizes.The transparent polycarbonate in material position that this sensor set collar uses, therefore little to the influence of user's reading.
