Description
The present invention relates to a kind of watt-hour meter, relate in particular to a kind of radio paging multifunctional watt-hour meter.Along with the raising of people's living standard, people are also more and more higher to the requirement of quality of life.Country is also actively carrying out infrastructure rebuilding to satisfy people's this needs.For example: the meter reading method of traditional ammeter, water meter, gas meter is too outmoded, and the person of checking meter needs reading of data from house to house, and is not only consuming time but also require great effort.At this situation, at present, many manufacturers have developed various novel electronic formula ammeters, electric water meter and electronic type gas meter, realize remote automatic meter reading by modes such as line of electric force, telephone wire and LAN (Local Area Network).The intellectual communityintellectualized village that has has also realized the meter reading method of " three table unifications " formula simultaneously.
China has two large problems at present in upgrading urban and rural power grids work:
1, multiple rate problem
Along with the transformation of State Grid's city net, rural power grids, simultaneously also along with the improving constantly, improve of the people's living condition, vast city, urban residents are also more and more high to the demand of electric power, and the imbalance between supply and demand of electric power certainly will be also more and more outstanding; How to encourage the many electricity consumptions of numerous residents, and don't cause the unbalanced of whole electric load, how to strengthen the management of power use, effectively utilize electric power energy, carry out " paddy is added in peak clipping, balanced load ", it is very urgent that this problem just seems.In order to make full use of existing transmission of electricity, join power-supply unit, improve plant factor, alleviate the imbalance between supply and demand of electric energy.Power department has proposed the policy of " electricity price is at pleasure chosen, period appoint you to select ", " time-of-use tariffs allow you be the electricity consumption owner ".At present domestic existing many producers have developed multi-rate meter and multi-function watt-hour meter according to these needs of power department.But there are suitable distinct issues in this watt-hour meter: how to change rate and check meter.Present mode mainly contains two kinds: manually with automatic.
A. manual mode
Handheld unit (HHU, hand-held unit, hand held programmable device and hand held meter-copy device) is the instrument of this kind mode.The specific implementation flow process is: earlier rate is arranged in the programmable device, carries meter-copy device from house to house to each ammeter programming by the staff again; When checking meter, the staff carries meter-copy device and from house to house data is copied back.The main drawback of this mode is that workload is very big, not only consumes manpower but also time-consuming, and can not solve the problem of owing electricity charges.
B. automated manner
Automatic meter reading system is the project of present all big enterprises emphasis tackling key problem, mainly contains by RS-485 standard serial electric interfaces to check meter and power carrier is checked meter two kinds.The major defect of this mode is the cost height, and needing increases many peripherals, and success ratio is low, poor reliability, and the while can not solve the problem of owing electricity charges.
2, pre-payment problem
User's owing electricity charges is another big problem that power department is run into, and the annual owing electricity charges of each province and city user does not wait to billions of units up to several ten million altogether.How to replace the traditional electrical kilsyth basalt, electricity back electricity consumption is purchased in realization earlier, the sale of electricity management modernization is the problem that power department is being studied always.The appearance of card prepay charging management system makes us see the hope that addresses this problem.Pre payment watthour meter has the function of electricity consumption behind the post-pay paystation, provides a kind of technological means for power supply department solves charging problem.Particularly those are subjected to the area of owing electricity charges puzzlement for a long time.Also because the expansibility of its management software also has been subjected to the welcome of administration departments in developed regions.Therefore, this is a kind of very promising electric energy instrument.
The form with slot meter occurs in Britain pre payment watthour meter as far back as the 1950's, because technology is advanced inadequately, relatively poor can not the obtaining of reliability promoted.Up to the nineties, along with electronic technology, development of computer, for bobbing up like a cork of pre payment watthour meter provides powerful technology backing.A kind of is that the data processing unit of core combines with common watt-hour meter with the microprocessor, has constituted pre payment watthour meter of new generation.It with management system for selling power (computer software), sale of electricity machine, purchase dielectric and form card prepay charging management system, implement the management of power supply and power utilization system of electricity consumption behind the post-pay paystation and carry out some daily management.
At present, domestic employing is maximum is that integrated circuit card (Integrated circuit (s) cards with contacts is called for short IC-card) with contact-carrying is as the card prepay charging management system of sale of electricity medium.This ammeter can promote the modernization of residential electricity consumption, the variety of issue that avoid checking meter, the shared watchband in many families comes because of manually registering one's residence, thereby be widely adopted in recent years.But the expert thinks that there is following subject matter in the IC-card ammeter: the one, and poor anti jamming capability, particularly Kai Fang read-write window is subject to outside world; The 2nd, the IC-card ammeter is difficult to evidence obtaining identification after being caused control system to lose efficacy by attack, and the electricity consumption dispute very easily takes place; The 3rd, the price height, the life-span is short, and comprehensive benefit is poor, and application risk is big; The 4th, be difficult to adapt to the requirement of electricity price change.Therefore, State Power Corporation determines a few days ago: should not select the IC-card electric energy meter for use in " Every household has an ammeter " improvement project.
Therefore, the object of the present invention is to provide a kind of radio paging multifunctional watt-hour meter, this electric degree can be realized long-range rate modification.

Fig. 3 is the structured flowchart of another example of radio call multi-function watt-hour meter of the present invention;
Fig. 4 is the structured flowchart of example of the bidirectional mode of radio call multi-function watt-hour meter of the present invention.
As shown in Figure 1, Fig. 1 shows the basic structure block diagram of radio call multi-function watt-hour meter of the present invention.It includes:
Multiple rate scale 4, this table is used to store multiple tariff data, and multiple tariff data can comprise period, period rate, consumption rate, entry-into-force time etc., and wherein the most basic data are period and period rate.Following table is an example of the multiple tariff data of storage in the multiple rate scale 4:
Rate consumption rate entry-into-force time period period
2.00 yuan of/kilowatt 1.5 yuan/kilowatt hours of 8:00-17:00 March 1 in 2000
Time＞50 kilowatt time
1.00 yuan/kilowatt 0.75 yuan/kilowatt March 1 in 2000 of 17:00-8:00
Shi Shiri
＞100 kilowatt hours
The division of period can be carried out according to actual conditions, has only divided two times in this example, but can be divided into a plurality of periods as required.Last table explanation, in the period of 8:00-17:00, the electricity consumption rate is 2.00 yuan/every watt-hour, thereafter consumption rate represents, (or by week or per diem) metering monthly, and consumption is in 50 kilowatt hours, its rate such as preceding, consumption surpasses the part of 50 kilowatt hours, and its rate is 1.5 a yuan/kilowatt hour.In the period of 17:00-8:00, the electricity consumption rate is 1.00 yuan/every watt-hour, and consumption rate is thereafter represented, (or by week or per diem) metering monthly, consumption in 100 kilowatt hours, its rate such as preceding, consumption surpasses the part of 100 kilowatt hours, and its rate is 0.75 a yuan/kilowatt hour.Last row: the entry-into-force time is represented, the time that the rate in the table comes into effect.
Clock 5, this clock 5 is used for timing, and the various modules of time data that need are used in the power supply kilsyth basalt; In this example, consistance when guaranteeing that clock 5 is walked in each watt-hour meter can also comprise a clock check and correction module 6, when control device 3 receives the clock examine statement, when just controlling 6 pairs of clocks of clock check and correction module 5 and carrying out the school, to guarantee the punctual timing of clock 5;
Metering module 7 includes a plurality of gauging tables in the metering module 7, the quantity of gauging table should be corresponding with the kind of multiple rate, that is, if 4 grades of multiple rates are arranged, then the quantity of gauging table should be 4, the power consumption of one grade of tariff period of the corresponding metering of each gauging table.In this example, multiple rate is 2 grades, promptly time of one day is divided into two periods, and then the metering module in this example 7 comprises 2 gauging tables (A, B);
The control of the controlled module 3 of the work of metering module 7, control module 3 reads the time data of clock 5 earlier, from multiple rate scale 4, search the rate of current period then according to time data, according to the rate that finds, drive in the metering module 7 and carry out the power consumption metering with the corresponding gauging table of this rate (A or B).For example, if the time data of the clock 5 that control module 3 reads is 10:00 in the morning, then control module 3 finds this time when multiple rate is the period of 2 yuan/kilowatt hour, therefore from multiple rate scale 4, drive and be somebody's turn to do multiple rate and correspond to gauging table (A), power consumption is measured.
Though, in the present embodiment, do not specify that gauging table is mechanical electronic type, still, the ordinary person in present technique field should be appreciated that in watt-hour meter of the present invention, no matter is mechanical or electronic type, can use.
The example of a simplification is not have the consumption rate, promptly, in multiple rate scale 4, there is not this column data of consumption rate, like this, can simplify calculating, in the above example, the computing carried out of accounting module 8 is: 40 (reading of gauging table B) * 1 (rate B)=200, (rate A)+120, (reading of gauging table A) * 2 (unit).
In multiple rate scale 4, it the 4th classifies the entry-into-force time as, and it does the time spent, judges the time of utilizing this multiple rate to charge of beginning by control module 3.Certainly, also can be without this entry-into-force time, like this, after receiving new rate, this new rate just comes into force.
Display 9, as can be seen from Figure 1, this display 9 links to each other with accounting module 8 with clock 5 respectively, therefore obviously, the effect of this display 9 be can read clock 5 current time data, for example date and time and the metering data that shows accounting module 8, promptly the electricity consumption amount of money of explicit user is convenient to check meter and charge.
In example shown in Figure 1, overcome the inconvenience of traditional multiple rate of multi-rate meter change.For the present invention, power supply administration can once finish the modification of multiple rate as long as once send the instruction of changing new rate by paging centers, has reduced cost.Realized fundamental purpose of the present invention.
Fig. 2 shows another example of the present invention.This example has been realized another object of the present invention.Its concrete structure as shown in Figure 2, it has increased prepayment meter 10 and power-off modular 11 on the basis of Fig. 1.
The effect of prepayment meter 10 is the pre-payment amount of money that is used to store the user.When the user after the electricity charge have been prepay by power supply administration, power supply administration sends the instruction that comprises advance payment by paging centers to this user's watt-hour meter.Control device 3 stores this advance payment in the prepayment meter 10 into after receiving this instruction.
User prepayment can adopt multiple mode, for example can arrive the given place advanced charge, also can then by Advise By Wire power supply administration, the amount of money on the card be increased in this user's the prepayment meter by buying the electricity card that stores certain amount of money.
Power-off modular 11 is used for after user's pre-payment exhausts, and the user disconnects this user's current supply circuit when in time not increasing payment in advance.Can prevent user's owing electricity charges effectively like this.
For different users, different outage grades can be set.For example, a threshold value can be set, when control module 3 detected the amount of money in the prepayment meter 10 and is lower than this threshold value, control module 3 just drove power-off modular 11 work, stops to this user's power supply.The size of threshold value can be set according to user's grade, and generally this threshold value is just less than 0.But for more special user, for example hospital etc. can be arranged to these users highest ranking, and whatsoever situation all can not be to these users' outages.
In addition, if control module 3 detect remaining sum in the payment in advance table 10 greater than outage threshold after, then just drive power-off modular 11 and quit work, recover to this user's power supply.
In order to allow the user know that the pre-payment amount of money is about to use up, as shown in Figure 3, also comprise an alarm module 12.This module is passed through the mode of sound or light or both combinations to User Alarms.When control module 3 detects the amount of money in the prepayment meter 10 and is lower than a threshold value (this threshold value being called the caution threshold value in order to distinguish mutually with above-mentioned outage threshold), alarm module 12 is just to User Alarms, increase payment in advance when reminding the user to use.
As shown in Figure 3, abnormal work module 13 and power failure protection module 14 in example shown in Figure 3, have also been increased.
Because watt-hour meter of the present invention adopts the paging mode, in order to prevent user's malice shielding watt-hour meter, make the watt-hour meter cisco unity malfunction, electric degree of the present invention can increase an abnormal work module.The principle of work of this module is, paging centers carries out the on-air testing instruction to each watt-hour meter at set intervals, abnormal work module 13 constantly detects control module 3 and whether does not receive this on-air testing instruction for some time continuously, if receive, represents that then watt-hour meter is working properly; If do not receive, then the expression or the working position of this watt-hour meter are outside the areal coverage of paging centers emission, or this watt-hour meter is shielded by malice.At this moment, abnormal work module 13 is earlier by alarm module 12 alarms.If this situation continues not become, then drive power-off modular 11 work, disconnect current supply circuit.
For the work electricity consumption of each module in the watt-hour meter, civil power can be used after the transformation rectification.But can not avoid the situation of mains failure to take place fully.In order to deal with power failure, in watt-hour meter, standby power supply can be set.On the other hand, also can increase a power failure protection module 14.When control module 3 detects mains failure, just with some data storage in accounting module 8, multiple rate scale 4, the prepayment meter 10 etc. in power failure protection module 14 so that during power recovery, recover these data.Control module 3 also can be saved in these data in the power failure protection module 14 termly.Nonvolatile memories such as power failure protection module 14 general employing EEPROM.
Equally, in example shown in Figure 1, also can increase this power failure protection module 14, be used for storing the data of accounting module 8 and multiple rate scale 4.
Previously described several example all is unidirectional example, and promptly paging centers sends signal instruction to watt-hour meter.The example of Fig. 4 then shows a two-way example, and as shown in Figure 4, it is to have increased following module on the basis of the described watt-hour meter of Fig. 1:
Respond module 17 after control module 3 receives instruction, is controlled this respond module 17 and is produced a response instruction, and send coding module 16 to by control module 3;
Data transmitting module 18 is used for the data of watt-hour meter are sent to coding module.Data in the watt-hour meter can comprise the continuous data (Fig. 1) of each gauging table in the metering module 7, the metering data (Fig. 1) of accounting module 8, the amount of money data (Fig. 2) in the prepayment meter 10 etc.
Though these modules are increased in the example shown in Figure 1 in the present embodiment, certainly, also can be increased in the example of Fig. 2, Fig. 3, its method is similar, just repeats no more at this.
