Description of the Invention: [Technical Field] The present invention relates to a booting method, and more particularly to a booting method for an energy collecting system. [Prior Art] Energy, which is commonly used today, such as coal, oil and natural gas, has caused great pollution to the environment and the reserves of these energy sources have been declining due to the high progress of human science and technology. Therefore, in the current awareness of environmental protection, there is no Polluted and inexhaustible natural energy is gradually becoming a new alternative energy source. In the case of today's solar energy harvesting systems, one or more sheets of solar panels, a control circuit and a storage unit are included. The solar energy collection system converts the sunlight into a power signal after receiving the sunlight through the solar panel, and then stores the power signal in the storage unit through the control of the control circuit, or supplies it to the target device. However, the source of power for the control circuit is also derived from the storage unit, that is, the control circuit needs to receive the supply power provided by the storage unit for normal operation. However, if the solar energy collection system is in a bad weather condition and has not been used for a long time (shutdown), the power stored in the storage unit will gradually disappear. At this time, when the solar energy collection system is restarted, the control circuit will The solar collector system will enter a dead state because the power supply cannot be converted and the solar panel cannot be converted into a power signal for use. Nowadays, in order to prevent the solar energy collection system from entering a state of death, an additional battery is added to the system, so that the solar energy collection system is powered on in the storage list, and the battery can supply the power required by the control circuit. '", when the solar energy collection system is turned on, the manual: adding power to the control circuit' enables the control circuit to convert the solar panel, and the force signal is stored in the storage unit to make the whole (four) unified into normal operation. However, whether it is an extra battery or a power supply method, the cost of the acquisition system will be increased and unrealistic. [Summary of the article]

步驟20’電壓調節單元2將電力訊號%轉換為一可使 控制单tc 3運作的供應電力Vp。配合參_ 3,本實施例 之電壓調節單元2其中包括有一第一電壓調節組η及一第 二電壓調節組22,第-電壓調節組21主要是在能源採集系 統100為正常運作模式時,將儲能單元5所輸出之一第一 電壓V0及一第二電壓V1進行升/降壓而產生能夠供應給後 端設備(target device)使用的電源;而在步驟2〇中,係使用 第二電壓調節組22將能源採集單元}轉換出的電力訊號心 進行升/降壓而產生供應電力Vp,以供應給控制單元3。 特別說明的疋,第一電壓調節組21與第二電壓調節組 22的内部電路相同,故以下將以第二電壓調節組22為例說 明。第二電壓調節組22具有一第一電壓調節器221及一第 二電壓調節器222,第一電壓調節器221及第二電壓調節器 222皆耦接於能源採集單元1,分別用以將電力訊號%升/ 降壓為一第一供應電力VS1及一第二供應電力VS2輸出, 在此會有兩個電壓調節器的原因是為了使本實施例之能源 採集系統100能夠供應兩種不同電壓值的供應電力Vp,以 7 201136085 符合各種控制單元3的規格, 實施例中’第一供應電力VS1 電力VS2的電壓值為4.2V。 但其數量不以此為限。在本 的電屋值為3.3V,第二供應 在此假設本實施例之控制單元3的製程係為.^(㈣製 程’因此,在第二電壓調節22轉換產生第一供應電力 VS1及第二供應電力VS2後,只將第—供應電力福傳送 至控制單元3,以供應控制單元3所需的電力。參閱圖卜 控制單元3具有—㈣模組31、—控制模組Μ及―計算模 組33,且充電單元4具有—功率點追蹤模組41及一充電模 組 42。 、 藉由第-供應電力VS1所提供的電力,控制單元3的 伯測模組3丨及控龍組32得以被開啟而進人正常運作, 特別強調的是,此時的控制單元3並非全部的電路皆被開 啟。偵龍組31在開啟後會執行㈣3(),偵㈣能單元5 中其中之一的儲能元件所儲存之電力是否低於一預設電 力’若是’則控制單元3的控制模組32執行步驟4〇,控制 充電單元4的充電模組42以―預設功率點對該儲能元件進 行儲能。 參閱圖4,儲能單元5具有三個儲能模組51,且三個 儲能模組51分別具有一儲能元件sc〇、SC1及sc2,在本 實施例中,每個儲能元# SC〇、Scl及SC2皆為超級電容 (supercapacitor),且其中之一儲能元件sc〇設計為開機儲能 及•件(booting supercapacitor)SC〇,其電容值會小於其他儲能 兀件SCI及SC2,因此,開機儲能元件sc〇可相較於其他 201136085 儲能元件SC 1及SC2更快速地充電至飽滿而供應給控制單 元3,使得控制單元3中的電路可以完全地被開啟而進入正 常運作模式。 因此,在步驟30中,偵測模組31係偵測開機儲能元 件SCO所儲存之電力是否低於預設電力,若是,即表示開 機儲能元件SCO的電力過低,則控制模組32控制充電模組 42以一預設功率點對開機儲能元件sc〇進行儲能,如步驟 40所述。在此所指的預設功率點係指能源採集系統上 次關機前,充電單元4對儲能元件SC1及SC2儲能時所採 用的最大功率點(maximum power p〇int),當然,也可以是設 計人員預先設定且儲存於控制模組32的一固定的最大功率 點。 在開機儲能元件SCO儲能結束後,提供給控制單元3 的供應電力Vp會從電壓調節單元2切換由開機儲能元件 SCO提供,使得控制單元3的内部電路(包括計算模組33)得 以全部開啟,此時,控制模組32會執行步驟5〇,控制充電 模組42以一最大功率點對其餘儲能元件SC1及sc2進行儲 能。值得-提的是,上述所指的「储能結束」,係指開機儲 能兀件sco充電至飽滿’但也可以是開機儲能元件sc〇充 電達到某-電壓準位後,即切換改由開機儲能元件sc〇提 供控制單元3所需的供應電力VP,故不以本實施例為限。 此外,在本實施例中,能源採集系統1〇〇係利用充電 單元4的功率點追蹤模組41及控制單元3的計算模組μ 的相互配合,而尋找出對應能源採集單元!的最大功率 201136085 點。首先,功率點追蹤模組41會先取樣出在不同的負載 下,此源彳木集單元i所轉換出的電力訊號Ve的電流與電 壓並將其傳送至計算模組33 ;接著,計算模組33會藉由 ^述電流與電壓描繪出一電流-電壓分部圖(I_V curve)而計 算出對應能源採集單元丨的最大功率點,如圖5所示。 參閱圖5,X軸為電力訊號Ve的電壓且丫軸(左)為電 力訊號Ve的電流,電流_電壓曲線L1係由計算模組33所 得到的各個電流及其對應的電壓描繪而成,而將各個電流 及其對應的電壓相乘後可得到電力訊號Ve的功率,如¥軸 (右)所示,功率曲線L2即是由各個功率值描繪而成。由功 率曲線L2可知,本實施例之能源採集單元丨的最大功率點 即出現在電力訊號Ve的電壓為5V且對應的電流約為 68mA。 在計算模組33計算出最大功率點後會告知控制模組 32 ’使得控制模組32控制充電模組42以該最大功率點對 其餘儲能元件SCI及SC2進行儲能,以提高能源採集單元 1的採集效率及縮短儲能元件SC 1及SC2的充電時間。特 別說明的是,上述所提及尋找出最大功率點的方法,僅提 供一實施例而已,其方法亦可以為内建一個對照表(table)於 控制單元3中,該對照表可以記載對應能源採集單元丨在 不同溫度、陽光強度等參數下最大功率點的位置,使得控 制模組32可以根據該對照表在不同的天氣狀況下選取出最 大功率點,故並不以本實施例為限。 整體而言,在能源採集系統1 〇〇剛開機時,若開機儲 10 201136085 能疋件SCO的電力不足該預設電力,則能源採集系統ι〇〇 會以能源採集單元1為整個系統供應電力的來源,以將部 份的控制單元3開啟而控制充電模組42以預設功率點對開 機儲能元件SCO儲能,直到開機儲能元件sc〇充電至飽滿 後,能源採集系統100才會進入正常運作模式,改以開機 儲能元件SCO為整個系統供應電力的來源,此時,充電模 組42則以最大功率點對其餘儲能元件sc丨及SC2儲能。 然而,在步驟30中,若開機儲能元件sc〇的電力超過Step 20' The voltage regulating unit 2 converts the power signal % into a supply power Vp which can operate the control unit tc3. In conjunction with the reference numeral 3, the voltage regulating unit 2 of the present embodiment includes a first voltage regulating group η and a second voltage regulating group 22, and the first voltage regulating group 21 is mainly when the energy collecting system 100 is in the normal operating mode. The first voltage V0 and the second voltage V1 outputted by the energy storage unit 5 are boosted/decreased to generate a power source that can be supplied to the target device; and in step 2, the system uses The two voltage regulation group 22 boosts/depresses the power signal core converted by the energy collection unit to generate the supply power Vp for supply to the control unit 3. Specifically, the first voltage adjustment group 21 is the same as the internal circuit of the second voltage adjustment group 22. Therefore, the second voltage adjustment group 22 will be exemplified below. The second voltage regulator group 22 has a first voltage regulator 221 and a second voltage regulator 222. The first voltage regulator 221 and the second voltage regulator 222 are coupled to the energy harvesting unit 1 for respectively The signal % liter/buck is a first supply power VS1 and a second supply power VS2 output. The reason for having two voltage regulators here is to enable the energy harvesting system 100 of the present embodiment to supply two different voltages. The value of the supplied power Vp is in accordance with the specifications of the various control units 3 in accordance with 7, 201136085. In the embodiment, the voltage value of the first supply power VS1 power VS2 is 4.2V. However, the number is not limited to this. In the present electric house value of 3.3V, the second supply assumes that the process of the control unit 3 of the present embodiment is . ((4) process' Therefore, the second supply voltage 22 is converted to generate the first supply power VS1 and the first After the power supply VS2 is supplied, only the first supply power is transmitted to the control unit 3 to supply the power required by the control unit 3. Referring to the control unit 3, the control unit 3 has - (4) module 31, - control module Μ and "calculation" The module 33, and the charging unit 4 has a power point tracking module 41 and a charging module 42. The power provided by the first supply power VS1, the test module 3 of the control unit 3 and the control group 32 can be turned on and enter the normal operation. It is especially emphasized that not all the circuits of the control unit 3 are turned on at this time. The detective group 31 will execute (4) 3() and detect (4) in the unit 5 after being turned on. If the power stored by the energy storage component is lower than a predetermined power 'if', then the control module 32 of the control unit 3 performs step 4, and controls the charging module 42 of the charging unit 4 to The energy storage component performs energy storage. Referring to Figure 4, the energy storage unit 5 There are three energy storage modules 51, and the three energy storage modules 51 respectively have an energy storage element sc〇, SC1 and sc2. In this embodiment, each energy storage element #SC〇, Scl and SC2 are super. Capacitor (supercapacitor), and one of the energy storage components sc〇 is designed as a booting supercapacitor SC〇, the capacitance value will be smaller than other energy storage components SCI and SC2, therefore, the starting energy storage component sc The 〇 can be charged to the control unit 3 more quickly than the other 201136085 energy storage elements SC 1 and SC2, so that the circuit in the control unit 3 can be completely turned on to enter the normal operation mode. Therefore, at step 30 The detecting module 31 detects whether the power stored by the boot energy storage component SCO is lower than the preset power. If yes, the power of the boot energy storage component SCO is too low, and the control module 32 controls the charging module 42. The power storage element sc〇 is stored at a preset power point, as described in step 40. The preset power point referred to herein refers to the energy storage system SC1 before the energy shutdown system is turned off. And the largest use of SC2 energy storage The power point (maximum power p〇int), of course, may also be a fixed maximum power point preset by the designer and stored in the control module 32. After the energy storage component SCO is stored, the control unit 3 is provided. The power supply Vp is switched from the voltage regulating unit 2 and provided by the power-on energy storage component SCO, so that the internal circuit of the control unit 3 (including the computing module 33) is fully turned on. At this time, the control module 32 performs step 5, The charging module 42 is controlled to store the remaining energy storage elements SC1 and sc2 at a maximum power point. It is worth mentioning that the above-mentioned "end of energy storage" refers to the charging of the energy storage component sco to fullness, but it can also be the power storage component sc〇 charging to reach a certain voltage level, that is, switching to change The power supply VP required by the control unit 3 is supplied from the power-on energy storage element sc, and is not limited to this embodiment. In addition, in the present embodiment, the energy harvesting system 1 uses the power point tracking module 41 of the charging unit 4 and the computing module μ of the control unit 3 to cooperate to find a corresponding energy collecting unit! The maximum power is 201136085 points. First, the power point tracking module 41 first samples the current and voltage of the power signal Ve converted by the source cluster unit i under different loads and transmits it to the calculation module 33; Group 33 will calculate the maximum power point of the corresponding energy harvesting unit 藉 by plotting a current-voltage partial map (I_V curve), as shown in FIG. Referring to FIG. 5, the X-axis is the voltage of the power signal Ve and the x-axis (left) is the current of the power signal Ve. The current-voltage curve L1 is drawn by the respective currents obtained by the calculation module 33 and their corresponding voltages. The power of the power signal Ve is obtained by multiplying the respective currents and their corresponding voltages. As shown by the ¥ axis (right), the power curve L2 is drawn by each power value. It can be seen from the power curve L2 that the maximum power point of the energy collecting unit 本 of the present embodiment is that the voltage of the power signal Ve is 5V and the corresponding current is about 68 mA. After the calculation module 33 calculates the maximum power point, the control module 32 is notified to enable the control module 32 to control the charging module 42 to store energy of the remaining energy storage components SCI and SC2 at the maximum power point to improve the energy collection unit. The acquisition efficiency of 1 and the charging time of the energy storage elements SC 1 and SC2 are shortened. In particular, the method for finding the maximum power point mentioned above only provides an embodiment, and the method may also be built in a control table 3, which can record the corresponding energy source. The position of the maximum power point of the acquisition unit 不同 under different temperature and sunlight intensity parameters, so that the control module 32 can select the maximum power point according to the comparison table under different weather conditions, and thus is not limited to the embodiment. Overall, when the energy harvesting system 1 is just turned on, if the power of the SCO is insufficient for the preset power, the energy harvesting system will supply the entire system with the energy collecting unit 1. The source of the control unit 3 is turned on to control the charging module 42 to store the energy of the power-on energy storage component SCO at a preset power point until the power-on energy storage component sc〇 is fully charged, and the energy harvesting system 100 In the normal operation mode, the power storage component SCO is used to supply power to the entire system. At this time, the charging module 42 stores energy to the remaining energy storage components sc丨 and SC2 at the maximum power point. However, in step 30, if the power of the power storage element sc〇 is exceeded
