Abstract
The method utilizes lines carrying periodically changed information, esp AC power lines for remote control and telecommunication. By using the line-inherent data as synchronous data, signal with definite phase or period, concentrated energy, short duration and high amplitude is transmitted. The present invention has high reliability, high noise immunity, low power consumption and less technological difficulty, and it is esp suitable for using power line for transmitting data of electric meter, water meter and gas meter.
Description
The circuit (being called for short circuit later on) that a kind of utilization has a cycle change information particularly AC-powered circuit carries out the method for remote control, communication.
The known method of utilizing supply line to carry out communication is that the carrier wave that load-modulate is crossed in supply line is realized.In carrier communication, information is by the amplitude modulation of carrier wave, frequency modulation being loaded and transmission.This method is because the time of amplitude modulation and FM signal busy line is long, and average power consumption is big, and transmitting power is restricted; While is strong owing to disturbing in the supply line, interference band is wide, load variations is big, realize normal accurate communication, and technical difficulty is big, cost is high, so all is difficult to use in a lot of occasions.
Task of the present invention is, utilizes circuit itself to have the condition of periodic signal, invents a kind of new remote control that average power consumption is low, signal is strong, technical difficulty is little, cost is low, the means of communication.
The present invention be achieved in that the circuit that has the cycle change information such as the AC-powered circuit in, all places that link to each other with this circuit can measure synchronous cycle information, and the signal that engraves when about phase bit of this cycle information or agreement can be received and determine according to a preconcerted arrangement its implication by any receiving system in this circuit.
The present invention at first formulates a communications protocol, to be defined as one or several information implications of determining in the agreement of cycle information constantly or on about phase bit or several specific signal, also can give no signal in or the arbitrarily individual cycle information specifically defined.According to this agreement, information definition is not the variation of basis signal frequency and amplitude, but basis signal residing phase place or constantly variation and having or not at whole cycle information in cycle information.The information that sends according to this characteristics can by one or several concentration of energy, the time is very short, amplitude is very big instantaneous signal the phase place of cycle information agreement or the time engrave emission and finish.
When carrying out communication by the present invention, the information that transmitter side will send by communications protocol about phase bit of respective cycle information and the time engrave one of emission or several concentration of energy, the time is very short, amplitude is very big instantaneous signal; Receiver side is being deleted the back (because the useful signal amplitude is very big with interference signal and noise signal, interference signal and noise signal are easy to deletion), thus with receive about phase bit or the time signal that engraves by circuit signal is widened and then demodulates information is come out to finish communication task according to communications protocol.If comprising remote control command, the information of communication can finish the remote control task.
The circuit (to call circuit in the following text) that a kind of utilization has a cycle change information particularly AC-powered circuit carries out the method for remote control, communication, in being utilized the circuit that carries out remote control or communication, have cycle information all synchronous in whole circuit (hereinafter to be referred as cycle information) at least, it is characterized in that:
A is according to communications protocol, about phase bit of respective cycle information or the time one or several signal specific engraving, represent one or information several agreements, that determine,
B about phase bit of cycle information or the time engrave one or several signal specific are signals that concentration of energy, duration are short, amplitude is bigger.
The present invention utilize in the circuit periodic signal of itself synchronous transmit and receive, make the cycle information particular phases and the time signal that engraves can carry out modulation and demodulation according to communications protocol, method is simple.Because the information in the communication is only relevant with the moment with the phase place of signal in cycle information and irrelevant with frequency and amplitude, therefore the signal of emission can be the instantaneous signal that a kind of concentration of energy, time are very short, amplitude is very big simultaneously.The amplitude of signal is big, has increased signal to noise ratio, has strengthened communication distance, has reduced the technical difficulty of modulation, has improved the reliability and the anti-interference of communication.Signal energy time of concentration is very short, has reduced average power consumption, has reduced cost, has reduced the volume of device.The present invention is particularly suitable for utilizing supply line that the field that kilowatt-hour meter, water meter, gas meter etc. carry out automatic data logging is used.Also can use at other similar applications.
About phase bit or the embodiment that constantly carries out remote control, the means of communication always send one or several phase test signals earlier before every transmission information in cycle information of the present invention, receiver side is revised phase place or moment benchmark always earlier by the phase test signal that receives.The information that arrives according to revised benchmark demodulate reception then.
The one-period signal phase or constantly the embodiment of benchmark cycle information is carried out zero crossing detect, produce zero cross signal and be benchmark with the zero cross signal or be benchmark with a certain definite moment or phase place behind the zero cross signal.
An embodiment of information definition method is with the particular phases behind the phase reference or constantly is defined as 0,1 ... .F or other information implication of determining.
Fig. 1 is one and sends the embodiment that signal produces.Unit [1] is a charhing unit, and capacitor C is an energy storage unit, and unit T is a coupling circuit, and unit [2] are control circuits, and it is by sending information circuit control.An embodiment charges to capacitor C at positive half cycle (or negative half period), in the about phase bit or the moment of negative half period (or positive half cycle), by control unit [2] is instantaneous energy among the energy storage capacitor C is passed through coupling unit T, be coupled in the circuit and send, finish the transmission of the strong signal of concentration of energy.
An embodiment of control unit [2] is made up of a unidirectional thyristor (controllable silicon), and the control utmost point receives the instruction from transmitter side, and anode connects coupling circuit.
An embodiment of charhing unit [1] is made of a current limiting element and the series connection of unilateal conduction diode.
An embodiment of control unit [2] is on a unidirectional thyristor side and a diode that conducting direction is opposite with the unidirectional thyristor conducting direction is arranged.
