4. Low-power-consumption safety lock based on photoresistance coding and decoding as claimed in claim 1, wherein the mobile terminal is installed on a mobile phone, the receiving terminal is installed on a door lock, and the operation method comprises the following steps:
a1, inputting the password into a password input module of the mobile terminal in the mobile phone, and compiling the password into a binary code through a first data processing module of the mobile terminal;
a2, the image processing module translates the binary code written by the data processing module I into an image sequence with equal intervals according to the rule that 1 corresponds to a white image and 0 corresponds to a black image;
a3, an APP sequence display module of the APP sequence conversion module converts the image sequence into a black, white, bright and dark image on the mobile phone screen through an optical conversion module;
a4, a photosensitive sensing module of a receiving terminal on the door lock forms a current input data processing module II carrying signals through a current forming module according to black, white, bright and dark images displayed by a mobile phone screen;
a5, data module analyzes and converts the signal current into corresponding binary code, and then converts it into cipher code to be input into cipher code receiving module;
a6, the password receiving module verifies the password and then opens the door lock.
5. The low-power-consumption safety lock based on photoresistance coding and decoding as claimed in claim 4, wherein the specific method for the photoresistance induction module to form the current carrying the signal from the black and white bright and dark image displayed on the mobile phone screen through the current forming module is as follows:
step 1, a photosensitive resistor of a photosensitive sensing module senses and translates a black and white bright and dark image flashing signal displayed on a screen of the mobile phone;
step 2, a singlechip of the photosensitive induction module inputs signals induced by the photosensitive resistor into a current forming module;
and 3, quickly forming a signal current carrying the input signal of the singlechip by the current forming module.
