紅外圖像檢測(cè)技術(shù)因具有非接觸、快速等優(yōu)點(diǎn)，被廣泛應(yīng)用于電力設(shè)備的監(jiān)測(cè)與診斷 中，而對(duì)設(shè)備快速精確地檢測(cè)定位是實(shí)現(xiàn)自動(dòng)檢測(cè)與診斷的前提。與普通目標(biāo)的可見光圖像相比， 電力設(shè)備的紅外圖像可能存在背景復(fù)雜、對(duì)比度低、目標(biāo)特征相近、長寬比偏大等特征，采用原 始的 YOLOv3 模型難以精確定位到目標(biāo)。針對(duì)此問題，該文對(duì) YOLOv3 模型進(jìn)行改進(jìn)：在其骨干 網(wǎng)絡(luò)中引入跨階段局部模塊；將路徑聚合網(wǎng)絡(luò)融合到原模型的特征金字塔結(jié)構(gòu)中；加入馬賽克 （Mosaic）數(shù)據(jù)增強(qiáng)技術(shù)和 Complete-IoU（CIoU）損失函數(shù)。將改進(jìn)后的模型在四類具有相似波紋 外觀結(jié)構(gòu)的電力設(shè)備紅外圖像數(shù)據(jù)集上進(jìn)行訓(xùn)練測(cè)試，每類的檢測(cè)精度均能達(dá)到 92%以上。最后， 將該文方法的測(cè)試結(jié)果與其他三個(gè)主流目標(biāo)檢測(cè)模型進(jìn)行對(duì)比評(píng)估。結(jié)果表明：不同閾值下，該 文提出的改進(jìn)模型獲得的平均精度均值優(yōu)于 Faster R-CNN、SSD 和 YOLOv3 模型。改進(jìn)后的 YOLOv3 模型盡管在檢測(cè)速度上相比原 YOLOv3 模型有所犧牲，但仍明顯高于其他兩種模型。對(duì) 比結(jié)果進(jìn)一步驗(yàn)證了所提模型的有效性。

The PW4556 series of devices are highly integrated Li-Ion and Li-Pol linear chargers targetedat small capacity battery for portable applications. It is a complete constant-current/ constantvoltage linear charger. No external sense resistor is needed, and no blocking diode is required dueto the internal MOSFET architecture. It can deliver up to 300mA of charge current (using a goodthermal PCB layout) with a final float voltage accuracy of ±1%. The charge voltage is fixed at 4.2V or4.35V, and the charge current can be programmed externally with a single resistor. The chargerfunction has high accuracy current and voltage regulation loops and charge termination

The PW4055 is a complete constant-current /constant-voltage linear charger for single cell lithiumion batteries.Its ThinSOT package and low external component count make the PW4055 ideallysuited for portable applications.Furthermore, the PW4055 is specifically designed to work within USBpower specifications.The PW4055 No external sense resistor is needed, and no blocking diode is required due to theinternal MOSFET architecture.Thermal feedback regulates the charge current to limit the dietemperature during high power operation or high ambient temperature. The charge voltage is fixedat 4.2V, and the charge current can be programmed externally with a single resistor. The PW4055automatically terminates the charge cycle when the charge current drops to 1/10th the programmedvalue after the final float voltage is reached. When the input supply (wall adapter or USB supply) isremoved, the PW4055 automatically enters a low current state, dropping the battery drain currentto less than 2μA. The PW4055 can be put into shutdown mode, reducing the supply current to 25μA.The BAT pin has a 7KV ESD(HBM) capability. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin to indicate charge termination and the presenceof an input voltage
