Abstract
The utility model relates to an infrared intelligent-card electric energy meter, particularly a precharge electric energy meter which transfers the information of the electric energy purchase and sale in a far infrared wave carrying mode. The electric energy meter is the equipment combined with an electric energy measurer unit based on the common electric energy meter and an infrared transmitting and data processing unit, the electric energy meter is matched with an infrared card (intelligent-card) held in hand to completely eliminate card plug-in mode in electric energy purchase and sale process and realize non-contact mode operation, in consequence, the unserviceable condition of the electric energy meter because of the imperfect confinement of the meter and socket fault is avoided, and simultaneously the personal safety and the convenient operation in electric energy consumption are ensured. In the accompanying diagram, the electric energy sale machine is matched with a general type computer and an infrared electric energy sale interface (electric energy sale machine) for use. When electric energy is on sale, the sale operation is finished by putting the infrared card opposite to the infrared electric energy sale interface and operating the electric energy sale machine. A user puts the infrared card opposite to his in-house using electric energy meter and operates the infrared card buttons to finish electric energy purchase process.
Description
The utility model relates to a kind of far infrared that utilizes for carrier, particularly can a distant place and the pre-payment electric energy measuring apparatus of contactless operation.
The frame mode of the current prepayment meter of being produced both at home and abroad has three kinds: be respectively the Electrical key type, socket-type electricity card and card form IC-card.Their principle of work and mode are with the IC circuit as the reading and writing data medium, operate to electrically contact mode.Determined them must carry out big change to the basic structure of ammeter thus: volume increases, ammeter externally must be provided with bayonet socket, correspondingly ammeter box also must be installed with redesign by opening, to bring a series of problem thus, as: the ammeter opening, with destroying the sealing of ammeter, influence work safety; The ammeter box opening easily causes the facility of stealing; The user is plug-in card repeatedly, climbs and also can cause trouble and unsafe factor.Especially the oxidation of deck reed and mechanical fatigue will cause operating malfunctioning, and electric weight such as can't import at fault, has directly influenced the safe and reliable operation of ammeter, also brings many inconvenience to the user.
The purpose of this utility model provide a kind of novel can straighforward operation and the prepayment meter of control.It utilizes data processing to combine with control technology and infrared communication technology, reaches that Touchless manipulation is purchased, the purpose of sale of electricity, and can guarantee safe, the long-term work reliably of operator and ammeter itself.
The purpose of this utility model is achieved in that with single-phase table or three phase watt-hour meter as measuring mechanism, after its measured electric flux (analog quantity) became digital quantity with analog to digital conversion circuit, input data processing unit (single-chip microcomputer) calculated and controls.Its infrared interface can accept to buy by oneself the data message of electricity card, and can be stored in the reservoir; The actual electricity consumption situation (data in the database) of this ammeter can also be fed back to by the infrared emission mouth simultaneously and purchase the electricity card, when purchasing electricity once more, the electricity consumption data are input in the database of electricity-selling system for future reference.Ammeter receive purchase information about power after, the user can normal electricity consumption, along with the increase of power consumption, the electric weight number of storage will successively decrease gradually in the table, when purchasing electric weight being used up (being decremented to zero), power supply is cut off in the tripping operation of ammeter gauge tap.Can continue electricity consumption after purchasing electricity once more.In using electric process, the electricity consumption situation of self is observed and grasped to display at any time.Can be by the LED of ammeter itself, operation user's the electricity card of purchasing reads data such as dump energy.In order to protect the safety of ammeter and consumer etc., ammeter also has overload protection and trip avoidance function.
The utility model circuit and simple in structure need not to do any change to the induction meter structure; All operations all are contactless and remote controls, have guaranteed the sealing and the reliability of ammeter, have also guaranteed the facility of security of users and operation.Got rid of because the fault that electricity card and deck loose contact, wearing and tearing or artificial destruction bring when purchasing the electric mortiser card and because of ammeter box be the stealing possibility that opening of card insertion causes.The utility model is suitable for new hypergene and produces; Also be suitable for old table transformation simultaneously.This saves the state fund input and will have very big benefit for making full use of re-using of existing device (or old assets), also be general money drawing plat can't accomplish.
The utility model is characterized in that it has comprised the electric energy measurement element, has also comprised the data processing unit that has infrared emission and receive the both-way communication interface; Infrared emission and infrared reception both-way communication interface also comprise an infrared modulation signal receiver-infrared receiving tube (TSOP5380) and an infrared modulation signal output device; Follower connects infrared transmitting tube after connecing amplifier again by schmidt shaping circuit serial connection gate circuit modulator.The data file eeprom circuit that this electric energy meter also comprises a loss of data when preventing to cut off the power supply connects monitoring circuit again; With it and deposit also have an EEPROM (MAX813) who has " house dog ".
The concrete structure of utility model is provided by following example and accompanying drawing thereof.
Fig. 1 is according to the schematic circuit that the utility model proposes.
Photoelectric commutator 01 is converted into the analog quantity of the ordinary electric meter reflective effect by the ammeter disk in the single-chip microcomputer of digital quantity (umber of pulse) input U1 among Fig. 1, carries out the conversion of electric weight and pulsed quantity; Infrared receiving tube U5 also imports in the U1 single-chip microcomputer after accepting to purchase electric quantity data.When external power failure (no working power), the data of single-chip microcomputer will deposit among the storer U3 automatically, and when working power was arranged, U3 can turn back to data and proceed computing among the U1.During user power utilization, the U1 electric weight that will successively decrease.When electric weight was kept to zero, relay R EL tripping operation was cut off the electricity supply.When re-entering electric weight, relay closes a floodgate and connects circuit.L1, L2 are infrared transmitting tube, and when importing electric weight with infrared card, it will return write information and send and be recorded in the infrared card for future reference.U4 is the LED light-emitting nixie tube, can show at any time that ammeter has related parameter.JZ is a sequential circuit, and working power is supplied with by transformer T, enters mu balanced circuit V1 after the ZL rectification.02 is the pulse delivery outlet.Other elements are the compensating circuit that improves the single-chip microcomputer operation conditions and set up.
Fig. 2 purchases the electric process synoptic diagram.The user holds the infrared sales department that is stuck in and purchases, marketing unit will purchase electric weight with the infrared sale of electricity machine that is connected in common computer RS232 interface and be input in the infrared card, the user holds at personal ammeter place by purchasing push button, can will purchase in the electric weight input ammeter, ammeter is interior if any dump energy, then the ammeter internal memory electric weight after the input is both sums, and can be read by light-emitting diode display.
