Abstract
The utility model relates to electrical meter field, which is an electrical meter with a computer fare register on common electrical meter. The electrical meter achieves a fire-new power supply management mode. The utility model adopts optoelectronic technology to send the sample into MM5736 computing unit after sampling to the electrical meter, and the result is sent into the display unit after calculating. The data signals from the outside charging card are sent into the MM5736 computing unit, and the result is sent into the display unit after calculating. The data from the outside charging card is sent into the MM5736 computing unit, and the electricity cost value has a new enactment. The control performance element automatically cuts power supply after the bought electricity cost (existing in charging card) runs out.
Description
The utility model relates to the watt-hour meter field, is a kind of watt-hour meter that increases the computer taximeter on the common electrical kilsyth basalt.
At present, there are following shortcoming in the whole nation and even external industry and the civil watt-hour meter that uses:
Manual metering charge, take a lot of work, time-consuming, to copy calculation wrong often.
2. least reasonably be the user " first electricity consumption, after pay the fees." power supply unit pays for the electricity charge first for the user, but also send someone to check meter everywhere to exact debit for collecting the electricity charge.
3. existing electric meter reading charge can not be pointed out user's saving consciousness, also is unfavorable for the macro-control of power supply unit.
The purpose of this utility model provides a kind of smart charge watt-hour meter that adopts photoelectric technology, microelectric technique to overcome above-mentioned shortcoming effectively.
The purpose of this utility model is to realize like this, it does not change the structure of former induction meter, adopt photoelectric detecting technology to measure the number of turns that rotating disk changes, the sampling unit (being the electricity consumption number of degrees) of forming electric power signal is converted into electricity charge number by calculating section, send display unit (liquid crystal display dish) to show.By the data-signal of paying dues that extrapolation electricity charge fare card is sent here, the input computing unit carries out the setting of new electricity charge total value.After the electricity charge that the user pays use up, cut off the electricity supply automatically by the power on/off performance element, stop the user being powered.
The utility model adopts photoelectric technology, new technologies such as CMOS micropower circuit and liquid crystal microelectronics, new material.Overcome the shortcoming of existing watt-hour meter function singleness effectively, have low in energy consumption, intuitive display, can show the electricity consumption number of degrees, the characteristics that can show the electricity charge amount of money again, its display circuit allow the electric consumer know its power consumption and the electricity charge at any time, can improve people's economize on electricity idea for this reason.When the paying electricity charge ran low, taximeter can the warning reminding electric consumer be changed electricity charge fare card, otherwise, after the paying electricity charge use up, promptly have a power failure automatically.
Below in conjunction with accompanying drawing, the utility model is described further.
Accompanying drawing 1 is a theory diagram of the present utility model.
Accompanying drawing 2 is the utility model infrared emission circuit.
Accompanying drawing 3 is calculating of the present utility model and power on/off executive circuit.
Accompanying drawing 4 is a value part circuit of the present utility model.
Accompanying drawing 5 is an infrared receiving circuit of the present utility model.
See Fig. 2: by the oscillatory circuit that integrated package 4069, resistance R 1, R2, capacitor C 1 are formed, produce the square-wave signal of 35KZ, drive the infraluminescence pipe then and send infrared light.See Fig. 5: by integrated package 4093 and resistance R 3, the infrared receiving circuit that capacitor C 2 is formed produces a full sized pules signal, delivers to 1 end of accompanying drawing 3, and the electricity charge are calculated.As shown in Figure 3: computing chip is made up of integrated package MM5736 and integrated package 4066 electronic switches, the pulse signal that infrared receiving circuit is brought is sent into integrated package MM5736 through integrated package 4066 electronic switches, integrated package MM5736 carries out following computing: the amount of money of paying the fees (unit)-X(changes) ÷ n(commentaries on classics/degree) * y(unit/degree), send display unit to show after having calculated.Display unit is made up of NSN66ALC display and DM75492 level controller.The power on/off control module is made up of with door integrated circuit block 4069 phase inverters and integrated package 4073, produces a signal when the electricity charge are 0, drives controllable silicon SCR the user is cut off the power supply, and when paying the fees again, produces a signal again, makes the controllable silicon conducting.Accompanying drawing 4 is provided with the unit for the electricity charge, produce the square-wave signal of 70KZ by integrated package phase inverter and resistance R 4, R5, capacitor C 3, the frequency dividing circuit of forming through integrated package 4013 carries out frequency division to the square wave of 70KZ, signal behind the frequency division is sent into the CP end of integrated package 4024 serial counters, produce an address 1 by the 9.6.11.12 end, read electricity charge number and watt-hour meter password among the fare card C850.Integrated package 4015 goes into and goes out shift register for book, integrated package 4028 is a BCD-+ system code translator, produces ten signals of Y0-Y9 and sends into counting unit, carries out the setting of electricity charge value.
Electricity charge fare card is made up of C850 static memory and miniature button cell, it can store the electric supply meter numbering, the electricity charge amount of money etc. of paying, have only when it inserts ammeter, electricity charge number could be received by watt-hour meter, and the setting of electricity charge number is to decide at the amount of money that charge station pays according to the user in the electricity charge fare card.
Claims (2)
