Problems solved by technology
Problems in the current application of this solution: When switching between induction power supply and battery power supply, the device needs to be powered off for a short time, and the energy loss of the battery cannot be replenished
Therefore, the current solution is difficult to effectively solve the problem of working dead zone, which greatly limits the wide application of induction power supply

The invention discloses an inductive power taking power supply system without a dead zone and a power supply management method. The inductive power taking power supply system without the dead zone comprises an inductive power taking device, a primary DC / DC module, a chargeable device, a power supply management module and a secondary DC / DC module, wherein the inductive power taking device comprises a power taking coil and the primary DC / DC module, and the power taking coil takes power from a power transmission line in an inductive mode; the primary DC / DC module outputs the electric energy obtained through induction; the power supply management module is connected with the output end of the primary DC / DC module and further connected with the chargeable device; the secondary DC / DC module is connected with the power supply management module, and the output end of the secondary DC / DC module is connected with a load; the power supply management module outputs corresponding control signals according to the input voltage of the primary DC / DC module, the voltage of the chargeable device and the input voltage of the secondary DC / DC module so as to control the on or off states between the chargeable device, the primary DC / DC module, the secondary DC / DC module and the load to enable the inductive power taking device and the chargeable device to continuously supply power for the load and enable the inductive power taking device to charge the chargeable device.
Description
technical field [0001] The present invention relates to a power management method and system, in particular to a power management method and system for inductive power acquisition. Background technique [0002] With the construction of the smart grid, the demand for installing smart electronic devices on high-voltage primary equipment (such as overhead transmission lines, cables, ring network cabinets, etc.) Directly obtain the required power supply, so the application of induction power supply is becoming more and more extensive. The minimum line current required by the power supply to output the rated load power is called the starting current of the power supply. If the device is only powered by a common power supply, when the line current is lower than the start-up current, the device will have a working dead zone due to power loss. [0003] The most common solution to the problem of the above-mentioned dead zone is to put the backup battery into power supply when sensi...
