Control unit for reconfiguring only the circuit of); And / or a battery that stores the energy collected by the energy collection circuit.

In order to prevent each of the energy collection circuits from reaching the saturation region according to the amount of power included in the SWIPT signal, the control unit reconfigures the number of the energy collection circuits to be activated. For example, when the received power is large, in order to prevent each energy collection circuit from reaching a saturation region, the control unit of the energy collection unit increases the number of activated energy collection circuits to lower the power input to each of the energy collection circuits. . Therefore, the number of energy collection circuits activated is proportional to the size of the received power.

When the communication mode is the ID mode, all the received SWIPT signals are transmitted to the information receiving unit. On the other hand, when the communication mode is the EH mode, the received SWIPT signal is transmitted to the energy collection unit and is used to collect energy. When the communication mode is the EH mode, the energy collection unit distributes the power of the received SWIPT signal to the activated energy collection circuit.

The EH mode selection area is as follows.

의 조건을 충족해야 한다. 즉, 본 발명에서 상기 λ는 EH/ID 모드 선택에 영향을 주는 중요한 변수이다. 상기 λ는 에너지 자립 조건을 충족해야 하며 이는 수신 전력과 회로의 소비 전력에 영향을 받는다. 예를 들어, 평균 수신 전력이 낮거나 회로의 소비 전력이 클 때 λ는 커지게 되며, EH모드 선택영역이 넓어진다. 즉, 에너지 자립 조건을 충족하기 어려우면 λ를 증가시켜 EH 모드의 영역을 넓힌다. 반면, 에너지 자립 조건을 충분히 충족시키면 λ를 감소시켜 EH 모드의 영역을 줄여 전송속도를 높인다.In the above formula, λ has one value within a given window size (W).

Must meet the conditions of That is, in the present invention, λ is an important variable that affects EH / ID mode selection. The λ must satisfy the energy independence condition, which is affected by the received power and the power consumption of the circuit. For example, when the average received power is low or the power consumption of the circuit is large, λ becomes large, and the EH mode selection area is widened. That is, if it is difficult to meet the energy independence condition, the region of the EH mode is widened by increasing λ. On the other hand, if the energy independence condition is sufficiently satisfied, λ is reduced to reduce the area of the EH mode to increase the transmission speed.

Referring to FIG. 8, the algorithm according to the method for receiving a SWIPT signal according to the present invention is largely composed of two loops, an outer loop and an inner loop. The inner loop operates as a short-term, and the outer loop operates for each window size (W) given as a long-term.

)이 EH 모드 영역일 때(

) 통신모드는 EH모드를 선택하고, 그렇지 않은 경우 ID모드를 선택한다. 본 다중 입출력 제어장치에서 EH모드가 선택되면, 상기 에너지 수집부는 최적의 수의 에너지 수집회로(120)의 활성화를 위해 재구성된다. 한편, 상기 Outer loop는 윈도우 사이즈 동안의 평균 수신 전력과 상기 inner loop동안 수집되는 에너지를 이용하여 λ를 업데이트 한다. 상기 업데이트된 λ에 따라 EH모드 또는 ID모드 선택영역이 변화하게 된다.More specifically, the multi-input / output control device has received power (

) To select the communication mode. The received power (

) Is in the EH mode area (

) Select EH mode for communication mode, otherwise select ID mode. When the EH mode is selected in the multiple input / output control device, the energy collection unit is reconfigured to activate the optimal number of energy collection circuits 120. Meanwhile, the outer loop updates λ by using the average received power during the window size and the energy collected during the inner loop. The EH mode or ID mode selection area changes according to the updated λ.

)를 얻을 수 있는 효과가 있다.This multiple input / output control device has an effect of securing a wide range of input power required for SWIPT by selecting a structure in which multiple reconfigurable energy collection circuits are configured in parallel. In addition, the power input to each energy collection circuit is controlled to be within a range having the optimal PCE to prevent the saturation region, thereby improving the overall PCE. In addition, since the overall energy collection efficiency is maximized and the energy collection unit is reconstructed according to the size of the received power, an input power of a wider area can be used. In addition, the reception environment is monitored according to the above algorithm to adjust the EH / ID mode selection area and the number of active collection circuits, thereby guaranteeing self-powering and at the same time optimal transmission speed (
