Document Type and Number:
WIPO Patent Application WO/2019/228086
Kind Code:
A1
Abstract:
The present invention relates to a key operation shielding type electric heater, comprising: a key disabling device which is respectively connected with each key of an electric heater and is configured to receive each signal of each key of the electric heater when an access granted signal is received and to shield each signal of each key of the electric heater when an access forbidden signal is received; an SD storage chip which is connected with a load on-site assessment device and is configured to store the weight of a camera itself and a preset difference threshold value; a spherical camera device which is configured to shoot an environment in which the electric heater is located for obtaining and outputting a corresponding electric heater environment image; and a type analyzing device which is connected with the spherical camera device for receiving the electric heater environment image and analyzing amplitudes of various kinds of noises present in the electric heater environment image, so as to determine a main noise type having the largest amplitude and a secondary noise type having the second largest amplitude. According to the present invention, directional shielding of unauthorized persons can be achieved.
