This switch gets up the metering signal and the power supply of microprocessor input control of unit quantity, per unit consumption (as 1 degree electricity, 1 ton of water, 1 cube of coal gas, or 10,100,1000 unit quantity) starts one bit microprocessor and reduces the computing of its former input consumption.
Switch one termination energize, the other end are divided into two the tunnel, the diode of leading up to is in parallel with card reader, and logical with the power supply of microprocessor termination again, another road is connected through resistance and microprocessor signals interface.
Switch also can lead to through timer, delay integrated circuit piece, electronic switch and power supply of microprocessor termination by diode is in parallel with card reader.
The card reader of one switch in parallel is IC-card or magnetic card reader.
Switch is made up of feeler lever and reed, and it is fixed on the support plate of counting gear top, reed is pressed to tooth mouth or shift fork below along carry gear or counting gear rotation direction, and feeler lever is arranged on the reed end of upspringing.
Controls is driving lever or briquetting, and its end is meshed with tooth mouth or shift fork, and the other end is near switch.
Switch can be other contact-making switches or light-operated switch or inductive switch.
Advantage of the present utility model is: compact conformation.Only do minimum improvement on original gear count table, and mix microprocessor, card reader and card get final product; Long service life.Microprocessor is an intermittent duty, power saving and the serviceable life of microprocessor and the mechanical life of gear count table are complementary; Applied range.Applicable to the cassette accounting management of the various tables that measure with the gear counting, as can be used for ammeter, water meter, gas meter etc.; The measuring accuracy height.The switch sampling is difficult for producing maloperation or phenomenon is lost in signal jitter, and microprocessor metering computing accurately and reliably.Multiple functional, various.The employing microprocessor signals is handled and computing is convenient, it is convenient to increase function, as is used for watt-hour meter, can increase the electric weight deficiency and report to the police, and the electric weight input adds up functions such as the power failure data protection and the delay protection that powers on; Use and management is convenient.Adopt the operation of magnetic card or IC-card, the amount of buying is used up automatic cut-out output, by off switch, electrically operated valve stop power supply, water supply or coal gas etc.
Description of drawings:
Fig. 1 is the utility model basic circuit synoptic diagram.
Fig. 2 is the block scheme that switch 1 is connected with microprocessor.
Fig. 3 is the structural representation of switch 1 and 7 engagements of carry gear.
Fig. 4 be switch 1 with operating rod 9 on counting gear 8 and carry gear 7, arrange structural representation.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Join referring to Fig. 1 switch one end and power supply, it is two the tunnel one the tunnel in parallel with IC-card or magnetic card reader through diode D that the other end is divided into, and logical with the power supply of microprocessor termination again, another road is through R
1, R
2Connect with the microprocessor signals interface.Between switch 1 and power supply of microprocessor end, can add oscillator J, delay integrated circuit piece I, reach electronic switch Q referring to Fig. 2.
During use, pay dues in table control material administrative authority (as power office, Running-water Company, Gas Company) earlier, being input in the card (IC-card or magnetic card) will block and insert card reader of the present utility model, microprocessor is opened and is deposited into a certain amount of use amount, o controller (as switch, electrically operated valve) is opened, export the material of table controls such as electricity, water, coal gas to the user, simultaneously, the gear count table is started working.Switch 1 intermittently conducting, when switch 1 conducting, above circuit opening power on the one hand drives microprocessor work, imported a certain amount of metering signal to microprocessor again on the other hand, so that carry out computing and data processing, reach the computing of reducing of consumption amount, amount is used up, and little processing is cut off output by o controller.Timer and electronic switch Q, for being started rapidly, reliably, microprocessor is provided with, and the adding of delay integrated circuit piece I, guaranteed that microprocessor has the sufficient time to carry out computing and data processing work, the unlikely microprocessor work that influences because switch disconnects at short notice after startup.The power supply that connects with switch is the direct supply that adapts with little processing, and this power supply can be exported from AC power in rectification, also can adopt accumulator to drive separately.
Be made up of feeler lever 2, reed 3 referring to Fig. 3 switch 1, it is fixed on the support plate 4 of carry gear top, and reed 3 is pressed to tooth mouth 5 along the direction that the carry gear rotates, and feeler lever 2 is arranged on the end of upspringing of reed 3.In like manner, this switch 1 also can be provided with above the counting gear shift fork.Switch 1 also can be fixed on the below or the side of counting gear 8 or carry gear 7, reliably is as the criterion with convenient installation sampling.Switch 1 is arranged on which rank of counting gear or carry gear and all can.With common induction type 5 peace ammeters is example, general this should be decided according to the size of power consumption sampling, be arranged on first for household electricity family switch 1, all can on second counting gear or the carry gear, at this moment electric weight sampling is with 1 degree, 10 degree are unit, when switch 1 adopt the version of feeler lever 2 and reed 3 and be arranged on first counting gear or the first carry gear on (being that the electric weight sampling is a unit with 1 degree), power load is 2 kilowatt hours, 1 every unlatching time once of switch is about 0.5-1 minute of the time that feeler lever 2 contacts with reed 3, and this time that has been enough to satisfy that microprocessor carries out computing is 2-5 seconds requirement.For unit electricity consumer or the bigger user of power consumption, switch can be arranged on the 3rd, the 4th counting gear or the carry gear, electric weight sampling at this moment is a unit with 100 degree, 1000 degree.Certainly, according to different samplings, should adjust accordingly its microprocessor.
And in Fig. 4, represented the form of the structure of two kinds of switches 1 and controls 9, and switch 1, available controls 9 are handled, and controls 9 can be driving lever 10, or briquetting 11, and its end is meshed with tooth mouth 5 or shift fork 6, and the other end is near switch 1.Driving lever 10 middle parts are with the fulcrum of support plate 4, and an end is pressed to tooth mouth 5, when tooth mouth 5 clockwise rotates, just promote the fulcrum of driving lever 10 on support plate 4 and rotate, and the driving lever other end just relies on switch 1 conducting.Briquetting 11 is above counting gear 8, and briquetting 11 1 ends can fall into shift fork 6, just rotates counterclockwise briquetting 11 jack-up when counting gear 8 in the drawings, and briquetting 11 other ends and switch 1 disengage, close, on the contrary conducting.Switch 1 can adopt touch switch like this, also can adopt non-contact switch, as light-operated switch, and inductive switch etc.
The utility model is used for the transformation of common motor meter, makes cassette ammeter, its measuring accuracy height, and use and management is convenient, and is reliable through long-term usability, operational excellence.
