Method for automatically switching between DC ice melting three-phase AC line

The invention relates to a method for automatically switching a DC ice-melting three-phase AC circuit. A DC ice-melting main loop comprises a rectifier, a control protection device, and DC side switches. A three-phase AC power supply is connected to a three-phase input of a valve group of the rectifier, namely a current converter. An anode output and a cathode output of the rectifier are connected to the three-phase AC circuit needing the ice-melting respectively through two groups of DC side isolation switches in a DC ice-melting mode to form the DC ice-melting main loop, and DC ice-melting is carried out on the three-phase AC circuit. The DC side isolation switches are controlled to automatically switch a three-phase conducting wire to connect the rectifier for the ice-melting by operating the control and the DC side isolation switches according to the operation state of ice-melting equipment. The operation of the rectifier and the DC side switches is controlled by an automatic sequence in the switching process. The method makes the three-phase conducting wire evenly heated, reduces the switch transferring operation of switching on or switching off the switches and the wire connecting work in ice-melting sites at the same time, and greatly improves the safety and reliability of systems.

Multi-power switch switching method and device

The invention discloses a multi-power witch switching method and a multi-power switch switching device. In the method, by acquiring locomotive accelerator pedal position information and/or locomotive load factor information, when the locomotive accelerator pedal position information is greater than the upper limit preset value of an accelerator pedal or the locomotive load factor information is greater than the upper limit preset value of a locomotive load factor, a multi-power switch is automatically switched to the maximum torque value and outputs the maximum torque value; and when the locomotive accelerator pedal position information is not greater than the upper limit preset value of the accelerator pedal or the locomotive load factor information is not greater than the upper limit preset value of the locomotive load factor, the multi-power switch outputs the torque value corresponding to the rotation speed of a locomotive according to a power limitation curve corresponding to the position of a selector switch handle, thus, when the selector switch of the locomotive runs in an underloading or medium loading state, and the locomotive needs more power output, the multi-power switch is automatically switched to the overloading position according to the judgment of the accelerator pedal position information and/or locomotive load factor information to ensure that the locomotive runs in the overloading state, so that the multi-power switch of the locomotive can be switched timely and the dynamic property and the economic operation property of the whole locomotive can be guaranteed. Meanwhile, the switching operation of a driver is reduced.

Voting method based on dual-channel voting system

The invention discloses a voting method based on a dual-channel voting system. When voting starts, an A channel main control computer sends a voting starting command to a B channel main control computer; the A channel main control computer and the B channel main control computer send the voting command to corresponding channels of dual-channel controllers to be in a voting state, and the dual-channel controllers collect key information and send the key information to the main control computers; the A channel main control computer and the B channel main control computer receive voting data sentby the respective channels and forward the received voting data to each other; the A channel main control computer and the B channel main control computer process the voting data of the two channelsrespectively, merge the processed data and count and display the merged data; and when voting terminates, the A channel main control computer sends a voting terminating command to the B channel main control computer, then the A channel main control computer and the B channel main control computer sends the voting terminating command to the corresponding channels of the dual-channel controllers, and voting is finished. According to the voting method, two real-time on-line complete voting links which backup each other are formed, area isolation is achieved on the premise of forming systems separately, common network attacks can be defended, and the robustness and the stability of an overall network system are enhanced.

Song playing method and apparatus, storage medium and electronic device

The invention discloses a song playing method and apparatus, a storage medium and an electronic device. The song playing method comprises the steps of obtaining a historical playing duration of a current song, wherein the historical playing duration is a duration of playing the current song once; judging whether the historical playing duration is smaller than a first preset duration or not; if the historical playing duration is smaller than the first preset duration, obtaining a historical playing frequency of the current song, wherein the historical playing frequency is in one-to-one correspondence with the historical playing duration smaller than the first preset duration; judging whether the historical playing frequency is greater than a preset frequency or not; and if the historical playing frequency is greater than the preset frequency, skipping the current song. According to the condition that the historical playing duration of the current song is smaller than the preset duration and the historical playing frequency is greater than the preset frequency, the current song is controlled to be skipped without being manually switched, so that the switching operation is reduced and power is saved.
