METHOD FOR ENERGY SAVING OF LOCKING SYSTEM Russian patent published in 2021 - IPC E05B47/00 G06F1/3206 

FIELD: energy saving.

SUBSTANCE: invention relates to the field of autonomous electronic technology powered by autonomous sources with a limited supply of energy and can be used in various electronic devices with autonomous power, with a short operating cycle, triggered if necessary by a signal, and with a long waiting cycle when it is required to consume a minimum of battery energy. A method for energy saving of the locking system by implementing the following steps: a scheme for saving the energy of the key battery in the electronic control board of the electronic key at the end of the working cycle, by a signal from the microcontroller from the second input OR picks up a signal that puts the controlled power source into an energy-saving mode, in which the power supply from the power source to the control circuit, including the microcontroller, is completely disconnected; if it is necessary to turn on the controlled power supply of the key, the electronic lock board receives power from the key battery and sends a special signal to the electronic key by transmitting a signal through the power supply voltage contact and through a specialized circuit for isolating the switch-on sign from an external event, an electric signal is excited by a special energy saving circuit, which is fed to the first input OR to turn the power source into operating mode for a time sufficient to start the microcontroller, at the same time, a specialized circuit for isolating a power-on sign from an external event does not use battery energy; the microcontroller, after initial initialization, with its output signal connected to the second input OR, outputs a signal to maintain the source in the switched-on state for the duration of the working cycle, after which the microcontroller removes the signal from the second input OR and switches the power source to energy-saving mode.

EFFECT: maximum possible energy saving of an autonomous power source.
