The invention provides medium-frequency power supply energy-saving control roll welding equipment and a welding method thereof. The equipment comprises a support, a fixed shaft, a rotating shaft, a rib penetrating disc and an annular positive electrode, wherein the rib penetrating disc and the fixed shaft are fixed to the support; the positive electrode is fixed relative to the rib penetrating disc and the fixed shaft; the fixed shaft, the rotating shaft, the rib penetrating disc, and the positive electrode are concentrically arranged from outside to inside; a negative electrode is fixedly arranged on the rotating shaft, a steel bar cage is arranged on the rib penetrating disc, and discharging sections are arranged at junctions of a main rib and auxiliary ribs; only when the negative electrode is rotated to the discharging sections, discharging occurs between the positive electrode and the negative electrode; and the positive electrode and the negative electrode stop discharging amongsections except the discharging sections. The welding method comprises the following steps that a plurality of discharging sections are arranged at the junctions of the main rib and the auxiliary ribsof the steel bar cage; only when the negative electrode is rotated to the discharging sections, discharging occurs between the positive electrode and the negative electrode; and the positive electrode and the negative electrode stop discharging among the sections except the discharging sections. According to the welding equipment and the welding method, the interval discharging sections of welding is calculated in an arithmetic control system through the collection of sensor signals according to the type of the steel bar cage actually produced, an automatic discharge welding function is realized, and therefore energy consumption is saved.

The invention provides a method for predicting watchdog resetting, a microcontroller and an embedded system. An MCU (micro control unit) enters an interrupt handling program according a running program to determine that watchdog resetting is to occur, and then a DDR (double data rate) is switched to a self-refreshing mode to wait for watchdog resetting, so that watchdog resetting can be predicted, then the DDR is switched to the self-refreshing mode before watchdog resetting occurs, data of the DDR cannot jump during watchdog resetting, and accordingly, abnormal behavior caused by data changes when the program runs can be reduced.

The invention relates to the field of aluminum electrolytic capacitors, and particularly relates to an automatic and accurate control structure for the cutter depth of a foil cutter for an aluminum electrolytic capacitor. The automatic and accurate control structure for the cutter depth of the foil cutter can rapidly, automatically and accurately control the required cutter depth, and the time required by manual adjustment is saved; and in the aluminum foil cutting process, necessary grinding times are carried out on a cutter due to abrasion, a newly-designed limiting block gauge is accuratelycorrected, and the accuracy of the cutter depth is guaranteed. Meanwhile, a whole cutter shaft device of the foil cutter is stable in work, cutter jumping is avoided, cut burrs are controlled to be below 0.03mm, the phenomenon that the capacitor is short-circuited and loses efficacy due to the fact that the cut aluminum foil burrs are too large is completely avoided, and the product quality of the aluminum electrolytic capacitor is greatly improved. In addition, the possibility that the cutter of the foil cutter is damaged is reduced, and the service life of the cutter is prolonged.
