Description
Technical field
The network carrier centralized meter-reading system that the present invention relates to the used ACTPIS of a kind of network carrier centralized meter-reading system (automatismconcurrent trigger prefabricate instruction storage) middleware and constitute by this middleware.
Background technology
China's power supply department working method is mainly still checked meter based on manual at present, and this working method labour intensity is big, and efficient is low, error rate and personal error height, and can't get rid of long-standing power stealing, electric leakage and owing electricity charges phenomenon.Along with China's development of electric power industry, the city implementation that Every household has an ammeter makes.Make the workload of checking meter sharply increase, power department presses for a kind of power utility check toll administration means convenient, meter register method and advanced person, science accurately and changes in the past passive situation, realizes electricity consumption, charge, management comprehensive informationization,
The appearance of low pressure carrier wave centralized automatic meter-reading the management level of power industry increases us.But the noise jamming on the power circuit is the insurmountable technical barrier of traditional carrier meter reading product at present.
Many household electrical appliance of Chinese family use especially at present aspect Interference Control, do not resemble abroad according to the strict control of certain standard.Cause on the low-voltage power line undesired signal very big, and various frequency is indefinite.Some change transformer is too outmoded, and self produces interference.Circuit many places joint, line impedance is big.For reaching the purpose of stretching resistance, many local electricities department low-voltage power line adopts the wire laying mode of hinge joint, and the signal that makes each go up mutually interferes with each other, simultaneously the situation that also exists civilian electricity and commercial power to mix in a large number.
Because the distance of the signal to noise ratio (S/N ratio) of data-signal decision transmission range, so the key of electric line carrier communication is exactly to design a special-purpose modem chip of powerful power line carrier.External many companies have released the power line carrier modem chip of oneself, and have formulated the standard of the suitable frequency range of power line carrier.Because external power line carrier modem chip is at this area electrical network characteristic, electric network composition, and generally is to design at the household internal robotization, therefore use all difficult people's will to the greatest extent at home.
Realize data communication on line of electric force, people have carried out a lot of trials.Line of electric force has the characteristic that variable signal decay, impulsive noise and continuous oscillation interference etc. are unfavorable for data transmission as a kind of communication transmission media.
Disturb in order to get rid of these, utilize at present in the product that line of electric force communicates, mainly adopt narrowband carrier FM communication mode, spread spectrum communication mode, three kinds of technology of " chain code " modulation narrowband carrier transmission technology.
1, traditional narrow carrier wave FM communication mode is the conventional art of a maturation.It is reaching practical standard aspect line of electric force analog communication, can accomplish to stride phase place even stride transformer and carry out communication on line of electric force, and cheap and more or less freely realization is so commonplace in application.But the shortcoming of this traditional narrow carrier wave FM communication mode maximum is to carry out the transmission of digital signal, can cause the serious distortion of signal to data signal transmission.
2, spread spectrum communication mode is the spread spectrum technic that a kind of carrier that has the collision detection function that utilizes similar Ethernet is intercepted multiple access CSMA/CD agreement.It utilize a series of very brief, can self synchronous sweep frequency chirp as carrier, this chirp has fixed mode, can be received by online any node.Have stronger antijamming capability and autocorrelation performance, can make all equipment on the network of being connected discern the distinct waveforms that any apparatus is from network sent simultaneously, and need between transmitting and receiving device, not carry out synchronously.But the spread spectrum communication mode transmission range is nearer, can only use the single channel frequency range, and the system cost height is difficult to realize duplexing digital communication.
3, " chain code " transmission technology is that the data decomposition of needs transmission is become the chain link template, sends through narrowband carrier FM modulation system; The take over party relies on the indication of chain link template to copy complete data more again.The plasticity of these templates and distortion tolerance can be adjusted automatically according to the characteristic of network.
Therefore can be in the environment of high interference, high distortion transmitting data information.But " chain code " modulation narrowband carrier transmission technology is to system reform cost height, and share the expenses is bigger, finally uses the user to be difficult to bear.
Summary of the invention
The purpose of this invention is to provide a kind of based on present domestic electrical network present situation, can make full use of in the present electrical network existing watt-hour meter transforms, construction cost is low, antijamming capability is strong, the network carrier centralized meter-reading system that collection is copied and transmitted the used ACTPIS of the reliable network carrier centralized meter-reading system of data (automatismconcurrent triggerprefabricate instruction storage) middleware and be made of this middleware.
ACTPIS middleware of the present invention comprises carrier repeater, it is characterized in that carrier repeater is provided with the Data Detection transmitter, this Data Detection transmitter comprises waveshape detector at least, storer, verification determining device and trigger, and the Data Detection transmitter is by following instruction sequences work: waveshape detector is read in data and send into storer, data enter message queue, data in the message queue are sent into the verification determining device by the principle of first in first out and are carried out integrity checking, checking data correctly then send data carrier repeater to carry out data output, otherwise to trigger send instructions to that waveshape detector is read in data again and with storer in the corresponding data deletion.
The network carrier centralized meter-reading system that above-mentioned middleware constitutes, comprise the concentrator of being located at transformer B front end, transmission line of information between main control computer and main control computer and the concentrator and modulator-demodular unit, it is characterized in that between concentrator and the electric supply meter linking to each other and be connected to the ACTPIS middleware by line of electric force, this ACTPIS middleware comprises carrier repeater, on carrier repeater, be provided with the Data Detection transmitter, this Data Detection transmitter comprises waveshape detector at least, storer, verification determining device and trigger, and the Data Detection transmitter is by following instruction sequences work: waveshape detector is read in data and send into storer, data enter message queue, data in the message queue are sent into the verification determining device by the principle of first in first out and are carried out integrity checking, checking data correctly then send data carrier repeater to carry out data output, otherwise to trigger send instructions to that waveshape detector is read in data again and with storer in the corresponding data deletion.
