The present invention discloses an information processing method and an electronic device. The method is applied to an electronic device including a display unit. The method includes: responding to displaying N application windows corresponding to N application programs currently running on the electronic device The preset operation is to obtain N application windows, the first application window in the N application windows is the window fully displayed by the display unit currently being operated by the user, and at least one second application window is not displayed in the N application windows It is completely displayed on the display unit, N is an integer greater than or equal to 2; N application windows are placed on a preset interface and the preset interface is displayed, wherein, on the preset interface, each application window of the N application windows do not overlap with each other, and allow the user to operate the application control on any one of the N application windows. Through the above technical solution, the technical problem in the prior art that the background application program is inconvenient to operate when multiple application programs are running is solved.

The invention discloses a power load balancing system for a power distribution network. The power load balancing system comprises a control master station and a plurality of commutation devices for switching access phases; when the power load of the power distribution network is unbalanced, the control master station is used for determining a phase switching pair and a corresponding adjustment quantity value, making the commutation devices which do not provide load devices with built-in magnetic movement parts with electricity in a source phase in the phase switching pair, selecting the marked commutation devices requiring phase switching in the source phase, selecting unmarked commutation devices requiring phase switching in the source phase if the marked commutation devices are not enough, wherein the sum of the power load of the selected commutation devices is equivalent to the adjustment quantity value, so that the power load of the power distribution network is balanced; and the control master station controls the selected commutation devices to switch the access phases into a target phase in the phase switching pair. Reduction and avoidance of commutation vibration and noise generated by the load devices, with the built-in magnetic movement part, of clients are facilitated, stable operation is kept, and harmonic interference with the power distribution network is reduced.

An online automatic control guide method. In an automatic mode, a control system modifies a control quantity u(k) according to an online guide control quantity u G (k), and the control system outputs the deviation Deltau GA (k) between the online guide control quantity u G (k) and an automatic output control quantity u A (k) and the increment Deltau A (k) of the automatic output control quantity u A (k); and in a serial mode, the control system modifies a given quantity r(k) according to an online guide given quantity r G (k), and the control system outputs the deviation Deltar GC (k) between the online guide given quantity r G (k) and a serial remote given quantity r C (k) and the increment Deltar C (k) of the serial remote given quantity r C (k). The method is applied in the field of automatic control and can modify the control output quantity and loop given quantity in different modes and realize online operation guide or preferential human interference at any time and avoid auto-manual switch operations required when modifying the control quantity in an automatic mode and avoid switch operations required when modifying the given quantity under serial control.

The invention discloses a dial switching circuit based on convertible multiple modules. The dial switching circuit comprises a control circuit, a first dial switch and a first three-in-one module. The first three-in-one module comprises a user submodule, a loop submodule and a magnet submodule. The output end of the first dial switch is connected with the first input end of the control circuit, and the first control end of the control circuit is respectively connected with the user submodule, the loop submodule and the magnet submodule of the first three-in-one module. According to the invention, the output interfaces of three-in-one modules can realize three types, switching operation is reduced, damage is avoided accordingly, and the cost and the time are reduced; by use of cooperation between two three-in-one modules, a four-wire audio communication interface module is realized; and at the same time, the magnet submodule is realized by use of the loop submodule, module multiplexing is realized, and the circuit cost is decreased. The dial switching circuit based on the convertible multiple modules can be widely applied to the technical field of communications.
