[0050] The implementation details of the technical solutions of the embodiments of the present application are elaborated in detail below:

[0051] Embodiment 1

[0052] Please refer to Figure 2 , Figure 2 which is a schematic diagram of the circuit structure of the integrated signal and energy receiver of the whole embodiment. The overall concept of this embodiment is: by providing an additional local oscillator signal a1 and sending it into a six-port network circuit that satisfies a specific phase relationship together with the received signal a2, four signals b3, b4, b5, b6 with characteristic phase relationships are output, and then the four signals b3, b4, b5, b6 output by the six-port network are respectively sent through a DC blocker and into the corresponding rectifier circuit to obtain various intermodulation signals of two signals including DC and AC. Among them, the function of the DC blocker (capacitor, parallel coupled line, etc.) is to block DC and pass AC, ensuring that the signals (b3, b4, b5, b6) can enter the rectifier circuit, but the rectified DC does not enter the six-port network and the intermediate frequency filter. Finally, DC energy and intermediate frequency signals are obtained through the DC bias circuit and the filter respectively. The function of the direct-through filter (inductor, low-pass filter, etc.) is to pass DC and block AC, ensuring that only DC enters the subsequent DC synthesis circuit. The function of the intermediate frequency filter (band-pass filter or low-pass filter) is to allow the required RF signal to enter the subsequent amplifier and isolate DC and other unwanted RF signals. b3 and b4, and b5 and b6 enter the operational amplifier respectively to obtain the I-channel signal and Q-channel signal with orthogonal phase relationships; the DC generated by the 4-channel rectifier circuit enters the DC synthesis circuit to obtain a DC signal. Figure 2 The I-channel signal and Q-channel signal shown are used as data reflecting the information of the received signal, and the DC signal synthesized by the synthesis circuit is used as data reflecting energy.

[0053] Specifically, please refer to Figure 3 , Figure 3 , which is a schematic flow chart of an information and energy integrated receiving method disclosed in an embodiment of the present invention. As Figure 3 shown, an information and energy integrated receiving method according to an embodiment of the present invention includes:

[0054] S1, input the local oscillator signal and the received signal of the receiver into a six-port network to generate a first signal, a second signal, a third signal, and a fourth signal having a phase relationship.

[0055] Further, in order to clearly illustrate this embodiment, refer to Figure 4 , Figure 4 , which is Figure 2 a schematic structural diagram of the specific implementation of the information and energy integrated receiver corresponding to this embodiment.

[0056] Among them, the six-port network includes a power divider 1, a first branch-line coupler 2, a second branch-line coupler 34, and a third branch-line coupler 56.

[0057] The step S1 of inputting the local oscillator signal and the received signal of the receiver into a six-port network to generate a first signal, a second signal, a third signal, and a fourth signal having a phase relationship includes:

[0058] Input the local oscillator signal a1 into the power divider 1 and output two sub-signals 1 and 2 with equal energy (not shown in the figure); input the received signal a2 into the first branch-line coupler 2 and output two signals as sub-signals 3 and 4 (not shown in the figure). Wherein, a1 is the local oscillator signal of the receiver, and a2 is the received signal carrying information.

[0059] According to the sub-signal 1 and the sub-signal 3 input into the second branch-line coupler 34 to output a first signal b3 and a second signal b4; wherein, the phase difference between the first signal b3 and the second signal b4 is 90 degrees; according to the sub-signal 2 and the sub-signal 4 input into the third branch-line coupler 56 to output a third signal b5 and a fourth signal b6; wherein, the phase difference between the third signal b5 and the fourth signal b6 is 90 degrees.

[0060] A power divider, a power divider is a device that divides the energy of an input signal into two or more outputs with equal or unequal energy. In this embodiment, the input local oscillator signal a1 is divided into two sub-signals 1 and 2 with equal energy. A branch-line coupler (orthogonal 90° hybrid) is a four-port network device, and the phase difference between the two output ports is 90°.

[0061] Specifically, in this embodiment, let the signal a 1 = A 1 cosω1 t, where A is the amplitude of the signal, ω is the frequency of the signal, and Δφ is the phase difference between the two signals.

[0062] The local oscillator signal a1 and the received signal a2 are passed through the power divider 1, the branch-line coupler 2, the branch-line coupler 34, and the branch-line coupler 56 in the above manner to obtain the first signal b3, the second signal b4, the third signal b5, and the fourth signal b6:

[0063]

[0064]

[0065]

[0066]

[0067] where j represents the signal ja 1 is 90 degrees ahead in phase of the signal a 1 and ja 1 = A 1 cos(ω 1 t + π / 2).

[0068] S2 passes the first signal, the second signal, the third signal, and the fourth signal through a rectifying circuit to generate corresponding DC signals and AC signals respectively.

[0069] Further, S2 passing the first signal, the second signal, the third signal, and the fourth signal through a rectifying circuit to generate corresponding DC signals and AC signals respectively includes: passing the first signal, the second signal, the third signal, and the fourth signal through a DC blocker and a rectifying circuit to generate the DC signals and AC signals included in the first signal, the second signal, the third signal, and the fourth signal respectively; where the DC blocker includes a capacitor or a parallel coupled line.

[0070] Specifically, in this embodiment, after the signal b i (i = 3, 4, 5, 6) enters the rectifying circuit, due to the non-linear characteristics of the device, various intermodulation components between the input signals will be generated at the output end of the rectifying circuit:

[0071]

[0072]

[0073]

[0074]

[0075] Among them, the intermodulation components c3, c4, c5, and c6 represent the output signals of the cross-modulation between the input signals (local oscillator signal, received signal). The intermodulation components are the products of cross-modulation. First of all, it must be generated when two or more signals act on a non-linear element together. k i is the amplitude coefficient of the output signal of the rectifier circuit, and k 0 is the DC signal output by the rectifier circuit. Among them, the intermodulation components c3, c4, c5, and c6 all include DC signals and AC signals.

[0076] S3, obtain the AC signals of the first signal, the second signal, the third signal, and the fourth signal, and respectively obtain the first radio frequency signal, the second radio frequency signal, the third radio frequency signal, and the fourth radio frequency signal through an intermediate frequency filter; generate the first information according to the first radio frequency signal and the second radio frequency signal; generate the second information according to the third radio frequency signal and the fourth radio frequency signal; the first information and the second information have an orthogonal phase relationship.

[0077] Furthermore, the intermediate frequency filter is a band-pass filter.

[0078] In the S3, obtaining the AC signals of the first signal, the second signal, the third signal, and the fourth signal, and respectively obtaining the first radio frequency signal, the second radio frequency signal, the third radio frequency signal, and the fourth radio frequency signal through an intermediate frequency filter includes:

[0079] Select the frequency difference between the local oscillator signal and the received signal of the receiver to be determined as the intermediate frequency signal.

[0080] Perform filtering according to the intermediate frequency filter to obtain the intermediate frequency signals corresponding to the first signal, the second signal, the third signal, and the fourth signal, and determine them as the first radio frequency signal, the second radio frequency signal, the third radio frequency signal, and the fourth radio frequency signal.

[0081] In the S3, generating the first information according to the first radio frequency signal and the second radio frequency signal; generating the second information according to the third radio frequency signal and the fourth radio frequency signal includes:

[0082] Input the first radio frequency signal and the second radio frequency signal into the first operational amplifier to generate the first information; input the third radio frequency signal and the fourth radio frequency signal into the second operational amplifier to generate the second information.

[0083] Specifically, in this embodiment, as Figure 4As shown, among various intermodulation components c3, c4, c5, c6 between input signals generated at the output end of the rectifier circuit, all except the DC signal enter the band-pass filter; among them, capacitor 32, capacitor 42, capacitor 52, and capacitor 62 are for blocking the DC signal from entering band-pass filter 3, band-pass filter 4, band-pass filter 5, and band-pass filter 6.

[0084] In this embodiment, usually the receiver system selects the difference between two input signals (local oscillator signal a1, received signal a2) as the intermediate frequency signal. Since a 1 = A 1 cosω 1 t, that is, the frequency of the intermediate frequency signal is the component of ω 1 -ω 2 Therefore, the output signals y3, y4, y5, y6 of band-pass filter 3, band-pass filter 4, band-pass filter 5, and band-pass filter 6 can be obtained:

[0085]

[0086]

[0087]

[0088]

[0089] After inputting y i (i = 3, 4, 5, 6) into the operational amplifier, I and Q signals are obtained:

[0090]

[0091]

[0092] S4, obtain the DC signals corresponding to the first signal, the second signal, the third signal, and the fourth signal and synthesize them to generate DC energy.

[0093] Further, the S4, obtaining the DC signals corresponding to the first signal, the second signal, the third signal, and the fourth signal and synthesizing them to generate DC energy, includes:

[0094] According to the first signal, the second signal, the third signal, and the fourth signal respectively passing through the direct-through filter, obtain their respective corresponding DC signals, and pass the respective corresponding DC signals through the DC synthesis circuit to generate DC energy.

[0095] Specifically, in this embodiment, as Figure 4As shown, due to the existence of capacitors 32, 42, 52, and 62, the DC signals output by rectifier circuits 3, 4, 5, and 6 can only enter the DC synthesis circuit through their respective corresponding inductors 3, 4, 5, and 6. At the same time, due to the existence of inductors 3, 4, 5, and 6, all AC signals cannot enter the DC synthesis circuit. Therefore, it can be obtained that:

[0096]

[0097] The DC signals entering the DC synthesis circuit are:

[0098] I = I 3 + I 4 + I 5 + I 6 = k 0

[0099] It can be seen from this result that the DC signals obtained through the four rectifier circuits at the back end of the six-port network are the same as the DC components obtained by inputting a 1 and a 2 into a rectifier circuit. That is to say, the six-port network will not affect the rectification effect of the received signal.

[0100] The finally output DC signal is:

[0101] I dc = k dc I

[0102] where k dc is the synthesis efficiency of the DC synthesis circuit.

[0103] In summary, the finally output synthesized DC signal in this embodiment is the energy; the output I and Q signals are used as the signals reflecting the information of the received signal.

[0104] In addition, this embodiment also proposes a circuit applied to a signal receiver. The circuit includes a six-port network, a rectifier circuit, an intermediate frequency filter, and a DC synthesis circuit; this circuit can also refer to Figure 2 , where:

[0105] The six-port network is used to generate a first signal, a second signal, a third signal, and a fourth signal with a phase relationship according to the local oscillator signal and the received signal input to the receiver;

[0106] The rectifier circuit includes a plurality of sub-rectifier circuits and is used to generate corresponding DC signals and AC signals by respectively passing the first signal, the second signal, the third signal, and the fourth signal through their respective sub-rectifier circuits;

[0107] The intermediate frequency filter includes multiple sub-intermediate frequency filters, which are used to obtain the AC signals of the first signal, the second signal, the third signal, and the fourth signal, and respectively obtain the first radio frequency signal, the second radio frequency signal, the third radio frequency signal, and the fourth radio frequency signal through their respective sub-intermediate frequency filters; generate the first information according to the first radio frequency signal and the second radio frequency signal; generate the second information according to the third radio frequency signal and the fourth radio frequency signal; the first information and the second information have an orthogonal phase relationship;

[0108] The DC synthesis circuit is used to obtain the DC signals corresponding to the first signal, the second signal, the third signal, and the fourth signal and synthesize them to generate DC energy.

[0109] Compared with the prior art, the local oscillator signal of the receiver and the received signal are input into the six-port network to generate the first signal, the second signal, the third signal, and the fourth signal with phase relationships; the first signal, the second signal, the third signal, and the fourth signal respectively pass through the rectification circuit to generate the corresponding DC signals and AC signals; obtain the AC signals of the first signal, the second signal, the third signal, and the fourth signal, and respectively obtain the first radio frequency signal, the second radio frequency signal, the third radio frequency signal, and the fourth radio frequency signal through the intermediate frequency filter; generate the first information according to the first radio frequency signal and the second radio frequency signal; generate the second information according to the third radio frequency signal and the fourth radio frequency signal; the first information and the second information have an orthogonal phase relationship; obtain the DC signals corresponding to the first signal, the second signal, the third signal, and the fourth signal and synthesize them to generate DC energy.

[0110] Compared with the prior art, in this embodiment, by providing an additional local oscillator signal, it is sent into the six-port junction circuit that satisfies a specific phase relationship together with the received signal, and then the output signal of the six-port network is sent into the rectification circuit to obtain various cross-modulation signals of two signals including DC, and finally the DC energy and the intermediate frequency signal are obtained through the DC bias circuit and the filter respectively, which can simultaneously realize the reception of energy and information, and the parameter selection between them does not affect each other.
