Abstract
The utility model relates to a quantitative recording device which comprises a counting part and a presetting part, wherein, the counting part is composed of an auxiliary wheel 8 which is arranged on the side surface of a hundred bit word wheel; the presetting part is composed of a presetting wheel, a driving wheel, a stepping motor, a transmission wheel, a luminous tube and a photosensitive tube. The presetting wheel and the hundred bit word wheel are sheathed on the same shaft, two auxiliary wheels are contiguous, and the luminous tube and the photosensitive tube are positioned on both sides of the auxiliary wheels 8 and 11. Detection areas are distributed at the edges of the side surfaces of the auxiliary wheels 8 and 11, and the number of the detection areas is corresponding to the digit of the hundred bit word wheel and the presetting wheel. The inner parts of the detection areas are provided with detection windows. The utility model has the advantages that the counting function and the automatic control function are mutually independent, the safe reliability is realized, the long lifetime is long, and the cost is low.
Description
The utility model proposes a kind of quantitative register that is applicable to the family expenses fare collection power meter, belong to photoelectricity automatic control technology field.
The fare collection power meter of Chu Xianing all adopts the light-to-current inversion technology in the market, the pulse that output is directly proportional with the revolution of watt-hour meter aluminium dish, by umber of pulse under the record of the counter meter in the one-chip computer, convert the electric degree number to, leave in the register in the one-chip computer, and with the electric degree number that presets relatively, if more than or equal to representing that promptly the user has used up the electric energy of being bought, one-chip computer is promptly controlled internal switch and is cut off the electricity supply.Because one-chip computer is by the AC rectification power supply or by rechargeable battery powered, all may make loss of data in the one-chip computer in case circuit outage or battery power exhaust, and causes energy loss.And because watt-hour meter is an on-line operation, to the performance and life-span of one-chip computer also be great test.
The purpose of this utility model provide a kind of have preset and quantitative register that automatically control function is not lost variable again.
Technical solution of the present utility model: comprise counting, presetting two parts forms, wherein segment count is in the side of hundred character wheels 1 wheel 8 to be set, presetting part is by presetting wheel 2, driving wheel 3, stepper motor 4, power wheel 5, luminotron 6 and photosensitive tube 7 are formed, driving wheel tube is on power axle 10, the rotation axis of stepper motor is by heel teeth 13 engagements of gear 12 with driving wheel, power wheel is taken turns engagement with driving wheel with presetting respectively, presetting wheel and hundred character wheels is enclosed within on the same axis 9, the wheel 8 that presets the wheel 11 of wheel side and hundred character wheels is adjacent, luminotron and photosensitive tube lay respectively at the both sides of wheel 8 and 11, wheel 11,8 lateral edge has all distributed with hundred character wheels equably and has preset the corresponding detection zone of the literal digital number of wheel, and detection window is arranged in the detection zone.
The non-detection window part and the detection window that preset in the detection zone of the jack per line in the detection zone of wheel wheel and hundred character wheel wheels are to cover mutually, and the non-detection window in the detection zone of the not jack per line on the different wheel partly and detection window do not cover mutually.Perhaps, interior non-detection window part and the detection window of detection zone that presets the jack per line in the detection zone of taking turns wheel and hundred character wheel wheels do not cover mutually, and interior non-detection window part and the detection window of the detection zone of the not jack per line on the different wheel is mutual covering.
The utility model has the advantages that and preset stoichiometric number and control these two functions automatically separate that the data of metering are never lost, security of system degree and reliability height; Compact conformation is replaced old-fashioned register, does not influence the measuring accuracy of former watt-hour meter, and is stable and reliable for performance, and long service life is with low cost.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing the 2, the 3rd, the example structure synoptic diagram of the wheel 11,8 in the utility model.
Further specify the technical solution of the utility model below in conjunction with accompanying drawing: preset ten detection zones on the wheel wheel side corresponding to presetting the literal numeral of wheel (0～9) number, hundred character wheels also are like this.Luminotron and photosensitive tube lay respectively at the both sides of wheel 11,8, when presetting wheel and hundred character wheels when being rolled to arbitrary position, all have detection zone to be between luminotron and the photosensitive tube, and the light that luminotron sends to arrive on the photosensitive tube through the detection zone of the detection zone that presets wheel and hundred character wheels.Detection window 15 in the detection zone 14 on the wheel 11,8 is made different shape, make and to preset certain number detection zone on the wheel character wheel 0～No. 9 only just can cover (or seeing through) luminotron when overlapping with the detection zone of the jack per line of hundred character wheels light.Photosensitive tube detects the light from luminotron, output signal, the power switch in the control watt-hour meter.When presetting wheel with hundred character wheel jack per lines, overlapping detection zone covers the light of luminotron, and photosensitive tube detects the light less than luminotron, and the output low level signal cuts off the power switch in the watt-hour meter.At this moment can preset the wheel numeral of overturning forward by step motor control, preset the electric weight of 100 degree.Because preset not jack per line of wheel upset back and hundred character wheels, overlapping detection zone hides the incessantly light of luminotron, and photosensitive tube detects the light of luminotron, and the output high level signal is connected the power switch in the watt-hour meter, and quantitatively register is normally counted.When the full 100 degree electric weight of meter, the user does not reinitialize the electric weight of 100 degree, and numeral of hundred character wheels upsets and presets the wheel jack per line, and the power supply in the watt-hour meter is cut off.The user wants to continue the electric weight that electricity consumption just must be reinitialized 100 degree.
