Abstract
The invention provides an electricity meter comprising a control module which is used for completing functions of controlling, data analysis and the like of the whole electricity meter system; a communication module which is connected with the control module in an interaction way and used for realizing communication with other devices via wired and wireless modes; and an electric wave time-checking module which is connected with the input end of the control module and used for receiving a standard time signal transmitted via radio and completing time checking. The electric wave time-checking module is arranged in the electricity meter so that the whole electricity meter system has an automatic time-checking function and is maintained to be accurately synchronized with national standard time automatically. Therefore, a problem of inaccuracy in time checking caused by problems of time checking time-delay and communication in an electric power system and an energy consumption monitoring system is solved.
Description
Technical field
The present invention relates to ammeter field, relate in particular to a kind of ammeter of function during with electric wave school.
Background technology
In present stage electric system and energy consumption monitoring system, for completing, the electric energy of each place, unit equipment is measured and monitoring, a large amount of ammeters need to be installed; Simultaneously will be by network system platform or energy consumption monitoring system platform by all ammeter connecting systems.In subsystem, the collection of electric parameter is all relevant with the time again, adopts each equipment integrated real-time clock function separately, when all equipment clocks are broadcasted school by system in legacy system.But along with the complexity day by day of system and the restriction of communication environment,, in process, often there is time delay, the problem such as cannot school time when in the school.
Summary of the invention
The object of the present invention is to provide a kind of ammeter that function can automatic correcting time during with electric wave school.
Correspondingly, a kind of ammeter of the present invention, comprises control module, for completing the function such as control, data analysis of whole electric meter system; The communication module being connected alternately with control module, realizes and the communication of other equipment by modes such as wire and wireless; Be connected with the input end of control module electric wave school time module, when accepting radioed time reference signal and completing school.
As a further improvement on the present invention, when described electric wave school module by electric wave to time when receiving the time reference signal transmitting with ratio long wave at national time service center and carrying out school.
As a further improvement on the present invention, described ammeter also comprises the electric parameter acquisition module being connected with the input end of control module, for gathering electric power signal for analyzing and testing.
As a further improvement on the present invention, described ammeter also comprises the human-computer interaction module being connected alternately with control module, for completing the operation interface such as key-press input, demonstration.
As a further improvement on the present invention, described ammeter also comprises the RTC module being connected with the input end of control module, for the generation moment of real-time clock with note particular event is provided.
As a further improvement on the present invention, described ammeter also comprises power module, is used to whole electric meter system power supply.
The invention has the beneficial effects as follows: module during by built-in electric wave school in ammeter, make whole electric meter system possess automatic time calibration function, and maintenance and automatic accurate synchronizeing of national standard time, thereby inaccurate problem when the problem such as time delay and communication causes school while having solved electric system and energy consumption monitoring system lieutenant colonel.
Accompanying drawing explanation
Figure 1 shows that the module map of ammeter of the present invention.
Embodiment
Describe the present invention below with reference to embodiment shown in the drawings.But these embodiments do not limit the present invention, the conversion in structure, method or function that those of ordinary skill in the art makes according to these embodiments is all included in protection scope of the present invention.
As shown in Figure 1, module 5, RTC module 6 and power module 7 when ammeter of the present invention comprises control module 1, human-computer interaction module 2, communication module 3, electric parameter acquisition module 4, electric wave school.
Described power module 7 is used to whole electric meter system power supply.Control module 1 is for completing the function such as control, data analysis of whole electric meter system, and it has contrary input end and output terminal.Described communication module 3 is connected alternately with control module 1, realizes and the communication of other equipment by the mode such as wired or wireless.Described human-computer interaction module 2 is connected alternately with control module 1, for completing the operation of the operation interface such as key-press input, demonstration.Described electric parameter acquisition module 4 is connected with the input end of control module 1, and it is for gathering electric power signal for control module 1 analyzing and testing., module 5 is connected with the input end of control module when in described electric wave the school, when accepting radioed time reference signal and complete the school of electric meter system.Described RTC module 6 is connected with the input end of control module 1, for the generation moment of real-time clock with note particular event is provided.
When in described electric wave the school module 5 by electric wave to time directly receive national time service center with ratio long wave transmit time reference signal, after built-in processor decodes is processed, when automatic-calibration timer is walked, time and the standard time that country keeps that radio controlled timepiece is shown keep precise synchronization automatically.
, module 5 receives when in electric wave the school to time signal the timing device of launching base platform be made with rare caesium (Cesium) atom, within 100,000 years, only have the error of a second, so can almost forever all remain on etalon time.2007, build up just " the continuous broadcast platform of national time service center low-frequency time-code " in Shangqiu, Henan by China national time service center, frequency of utilization is 68.5KHz, starting formally to provide code to China is the CNS electric wave timing code of BPC.
Module when the present invention passes through to the built-in electric wave of ammeter school, make whole electric meter system possess automatic time calibration function, and maintenance and automatic accurate synchronizeing of national standard time, thereby inaccurate problem when the problem such as time delay and communication causes school while having solved electric system and energy consumption monitoring system lieutenant colonel.
Be to be understood that, although this instructions is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should make instructions as a whole, technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
Listed a series of detailed description is above only illustrating for feasibility embodiment of the present invention; they are not in order to limit the scope of the invention, all do not depart from the equivalent embodiment that skill spirit of the present invention does or change and all should be included in protection scope of the present invention within.
