The photoelectric direct reading mechanism 135 comprises a turntable 1350 arranged at the top of the transmission shaft 131, a disc position hinging shaft 1351 is vertically arranged at the edge of the end surface of the turntable 1350, a transmission crank 1352 is hinged on the disc position hinging shaft 1351, a displacement guide 1353 is arranged at the center of one side of the turntable 1350, a reflecting slide 1355 is arranged on the displacement guide 1353 in a sliding manner, and the reflecting slide 135 is arranged on the reflecting slide 1355The top of the frame 5 is provided with a far-end hinged shaft 1354, the end of the transmission crank 1352 is hinged to the far-end hinged shaft 1354, the two ends of the displacement guide 1353 are provided with a microswitch 1357, and the side of the displacement guide 1353 away from the turntable 1350 is provided with a laser displacement sensor 1356. The centering means that the axial center line of the displacement guide 1353 is orthogonal to the center line of the turntable 1350, i.e. the turntable 1350, the disk hinge shaft 1351, the transmission crank 1352, the displacement guide 1353, the distal hinge shaft 1354 and the reflective slider 1355 form a centering crank-slider structure to convert the rotation of the turntable 1350 into the linear reciprocating motion of the reflective slider 1355.

The transmission shaft 131 drives the main gear 132 to rotate, and further drives the driven gear 133 to rotate, and further drives the rotation shaft 136 to rotate, and further drives the two rotating discs 1350 to rotate synchronously. The fixing frame 134 includes a supporting post 1342 and a rotating sleeve 1341 disposed at the top of the supporting post, the rotating shaft 136 is rotatably sleeved in the rotating sleeve 1341, and the supporting post 1342 is connected to the watch body 10.
The two photoelectric direct reading mechanisms 135 can be mutually standby, and the laser displacement sensor 1356 of any one photoelectric direct reading mechanism 135 can be independently started to finish meter reading, so that the power consumption is reduced.
The axial center lines of the displacement guide rails 1353 of the two electro-optical direct reading mechanisms 135 are perpendicular to each other, that is, the moving directions of the two reflective sliders 1355 are perpendicular to each other, and the center lines of the two disk position hinge shafts 1351 are collinear, that is, the rotation of the two rotating disks 1350 are in a mirror reflection relationship. Any two photoelectric direct reading mechanisms 135 are selected as a main reading mechanism, and the other one is selected as an auxiliary mechanism. The reels 1350 of the two electro-optical direct reading mechanisms 135 rotate synchronously, and as shown in fig. 9, the main reading mechanism reads the position amount of the reflective slider 1355 on the displacement guide 1353, and obtains two angle values corresponding to the reels 1350, such as an angle value a represented by the tray hinge axis 1351 shown by a solid line and an angle value B represented by the tray hinge axis 1351 shown by a dotted line in fig. 9. According to the mirror reflection correspondence, when the actual angle value is a, the position of the reflective slider 1355 of the auxiliary mechanism is shown as the position P1 shown by the solid line in fig. 10, and when the actual angle value is B, the position of the reflective slider 1355 of the auxiliary mechanism is shown as the position P2 shown by the broken line in fig. 10, and the angle value of the main reading mechanism can be distinguished by reading the position of the reflective slider 1355 of the auxiliary mechanism. The water flow can be calculated by the two photoelectric direct reading mechanisms 135 without the switching signal quantity of the micro switch 1357, so that the failure of the micro switch 1357 due to faults or the loss of the switching signal quantity due to various reasons can be avoided, and the meter reading direct reading can be realized in the real sense.
The hinge force receiving portions of the distal hinge shaft 1354 and the driving crank 1352 are provided with pressure switches for detecting whether the reflective slider 1355 is actuated.

The method can finish meter reading by only using one photoelectric direct reading mechanism 135.

S311: the sub-controller 121 detects whether the reflective sliding block (1355) moves or not through the switching value signal of the pressure switch, after receiving a meter reading instruction, the sub-controller 121 checks whether the switching value signal of the pressure switch exists in a time period from the last meter reading, if so, the meter reading is performed through the metering component 13, and if not, the meter reading process is ended and the integrated meter head 200 is notified.
If the pressure switch does not have a switching value signal in the two meter reading periods, the laser displacement sensor 1356 is not needed to be used for detection, and the energy consumption is further reduced.
S312: the sub-controller 121 selects any one of the photoelectric direct-reading mechanisms 135 as a main reading mechanism, and the other one of the photoelectric direct-reading mechanisms is used as an auxiliary mechanism, the main reading mechanism reads the position quantity of the reflective slider 1355 on the displacement guide 1353, obtains two angle values corresponding to the turntable 1350, and determines a correct value in the two angle values according to the position quantity of the reflective slider 1355 of the auxiliary mechanism, so as to determine the water flow rate.
In the method in step S312, the water flow can be calculated by the two photoelectric direct reading mechanisms 135 without the number of switching signals of the microswitch 1357, so that failure of the microswitch 1357 due to failure or loss of the number of switching signals due to various reasons is avoided, and meter reading is performed in a true sense.
In the various meter reading methods described above, the farthest position of the reflective slider 1355 from the turntable 1350 is set as a metering starting position, so as to facilitate meter reading calculation.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
