The invention provides a low-power-consumption near-field
coupling energy supply OTA circuit, belongs to a
wireless software upgrading technology, aims to solve the
wireless upgrading problem of a GNCE
control system, and comprises a near-field
coupling energy supply module which is used for locally supplying energy to the
system, eliminating
system placement direction limitation and switching resonant frequency through a self-adaptive
resonance matching unit to realize the optimal
energy supply efficiency. A primary power supply is output to the
power management module, and the energy supply state is monitored in real time; the
power management module is used for providing a secondary power supply for the OTA security
upgrade verification module and the OTA
upgrade task execution module according to a preset power-on
time sequence and an enabling sequence; the OTA security upgrading
verification module is used for judging the security of a
system and a source program, confirming feedback through double channels of a visual
signal and a
wireless encryption signal, ensuring the security and accuracy of an upgrading process, supporting remote and local double supervision and preventing
software burning failure and tampering; and the OTA
upgrade task execution module executes the functions of upgrade
process control, state monitoring, program receiving,
verification,
backup, burning,
rollback and the like.
