Embodiment
Embodiment 1, referring to the drawings 1.
In the present embodiment, pulse signal transmission system includes passive transmitter 1 and communicates therewith the signal receiver of coupling
2, in same system, the pulse transmission system includes at least two passive transmitters and signal receiver, and all is passive
Emitter can be to signal receiver transmission signal.The emitting module of the passive transmitter 1 including signal, transduction assembly and whole
Component is flowed, transduction assembly is the equipment that can be absorbed other energy and be converted to electric energy, including thermoelectricity interchanger, solar energy hair
Motor, transduction assembly collect external energy and are converted to electric energy, are sent to rectifier stack, rectifier stack is connected to by transformer
Signal transmission component schedules to last the electric energy provided needed for transmission signal, and passive transmitter also includes first antenna component, and signal receives
Machine is provided with the second antenna module with first antenna component matching.The biography for detecting conversion efficiency is additionally provided with transduction assembly
Sensor.
Embodiment 2, referring to the drawings 1-3.
The present embodiment carries out pulse signal transmission using the system of embodiment 1, and in the present embodiment, main purpose is to avoid
Or alleviate the influence that other disturbing pulses of periodic emission are brought, possible interference effect is such as week from electric network power line
Phase property AC signal（Such as sine wave）And its clock can be between 50 to 60Hz frequencies and corresponding 16 to 20ms.
According to the transmission method of the present invention, transmission rate, such as data transmission rate may be selected>100Kbit/s, it can pass through
Small byte number is transmitted it is believed that breath and selection respective bandwidth are realized, the time for launching electric pulse is arranged to sufficiently small to avoid
Other periodic disturbances pulses, such as the interval slots much smaller than other periodic disturbances pulses twice, in this timeslot can be by upper
State emitting module and transmit interference-free electric impulse signal.The electric impulse signal can be launched several times to launch in first time
Electric pulse can be sent by the electric pulse of second of transmitting follow-up during a periodic disturbances superimposed pulses during the time slot.
The corresponding bandwidth of the transmission signal also can be selected accordingly.In the case, low-frequency electrical caused by any transduction assembly
High-frequency signal can be converted to by the high-frequency oscillating circuits coupled with above-mentioned transformer rear class and be suitable for remote transmission, at one
In example, the digital signalling is sent using 500KHz frequencies.
On the premise of transmitting power consumption then keeps constant, increase bandwidth may reduce signal transmission distance.And in some realities
In existing, the reduction of transmitting/range of receiving can also be received, such as indoors or between building.Because the circuit of emitter configures
Energy consumption efficiency, because shorten transmission this body length of signaling and accordingly reduction transmission power caused by low-power consumption can bring it is higher
Emitter service efficiency.
By identical signaling repeat send can repeatedly make it is at least one transmitting signaling can interference-free be sent to signal receiver end,
Time slot between the electric pulse of selection twice emitting can be set to the Period Slot equal to other periodic disturbances pulses.For example, honeybee
Multiple periodic emission pulses that the frequency multiplex Sexual behavior mode of nest mobile phone is brought have about 140 μ s time slot, therefore above-mentioned
Emitting module can preferably be arranged to 140 μ ss of the selection equal to honeycomb mobile telephone network and equal to electric network power line network
15 to 20ms time slot.
In the maximum magnitude that signal can transmit, it is also possible to exist indefinite quantity same type transmitting electric impulse signal or
Other pulses simultaneously disturb this that to be launched electric pulse.In order to improve the transmitting electric pulse can interference-free stable feeding up to described
Signal receiver, in other preferred embodiments, the different cycles between the electric pulse launched can be additionally provided.For example,
At the same time or not timing synchronously launch radio frequency electric pulse using the passive transmitter of two same types during, possibility
The problem of existing be the electric impulse signal from the two passive transmitters time slot or frequency it is identical or approximately the same, therefore should
Signal receiver is arranged to select the one of electricity of wherein processing after the electric pulse from the two passive transmitters is identified
Pulse, and post-process another in a preset time.
Fig. 2 electrical power/time diagram shows the efficiency electric energy E under different bandwidth1With non-efficiency electric energy E2Component and
Corresponding shorter or longer launch time T1, T2.Therefore, in short launch time T1Under high bandwidth 9 and gross electric capacity P, non-effect
Rate power component E2It is significantly less than efficiency power component E1。
According to transmission method above, supply the emitting module of passive transmitter 1 electric energy E be divided into transmitting processing during
Efficiency（Also may be defined as " active "）Electric energy E1With non-efficiency（Also may be defined as " idle "）Electric energy E2, efficiency electric energy E1Will
It is converted into radio frequency transmissions and non-efficiency electric energy E2Any efficiency is not produced and causes the emitting module and its electronic component
Temperature raises.
Low-power consumption can be realized in theory and then reduces transmission power, and transmitted bandwidth used will not cause identical low work(
Consumption, its reason are that caused loss can not be lowered to and transmission power and bandwidth identical level in circuit configuration.In signal
Narrower bandwidth under, it is necessary to longer launch time, in other words, in view of same circuits power consumption, non-efficiency electric energy and efficiency electric energy point
The ratio of amount substantially becomes big.
According to Fig. 2, reactive component can be reduced using increasing bandwidth and correspondingly reducing launch time, circuit power consumption
It is acceptable to keep constant and transmitting boundary reduction.
In view of improvement and its caused energy utilization rate of the non-efficiency electric energy to efficiency electric energy ratio, this method utilizes superfluous
Remaining and multiple radiation pattern increases transmission stability.According to this method, the transmitting procedure shown in Fig. 3 can be selected by this way
Select：Time slot TS between twice emitting is a fixed time slot or randomly selected variable slot.
Fig. 3 gives three pulse signal figures, wherein, the first signal S1 represents to be believed according to the transmitting electric pulse of the present invention
Number, the signal includes low volume data information and with the fixation time slot TS between twice emitting pulse1And random slot TS2, signal
S2 represents period 1 disturbing pulse caused by other emitters, and signal S3 then represents second round disturbing pulse.
Stackable the first pulses to present invention transmitting electric impulse signal of first disturbing pulse S1 are to disturb its reception, equally
Ground the second interference signal S2 can be in fixed time slot TS1It is superimposed to disturb its reception in subsequent pulse, here, in fixed time slot
TS1The signal of period transmitting meets with the lasting interference for coming self-interference signal S2 and S3.But use random slot TS2This can be avoided
For second interference signal S3 to subsequent exomonental superposition, possible factor is that the time slot two emission process or pulse is selected
Select.The time slot under this mode between two emission process can reasonably and be preferably selected, the time slot is different from conventional interference letter
Number pulse period.
