step two: when the input prompt errors are all input, prompting the user again to perform secondary verification or sending a confirmation instruction to the mobile terminal of the user by one key, and performing remote unlocking after the user invokes the monitoring picture of the user to confirm by the mobile terminal, wherein the user directly triggers an alarm instruction and simultaneously sends the alarm instruction to the mobile terminal of the user after the secondary verification fails again;
when the face recognition verification fails, acquiring a monitoring picture of the user, analyzing the monitoring picture, extracting man-made information in the picture, comparing and analyzing clothing information with pre-input clothing information of an express or takeaway, and if the analysis result is accordant, generating a visit signal and sending the visit signal to a mobile terminal of the user to prompt the user to visit the express or takeaway; if the clothing is not matched, the previous identification picture is further retrieved to be matched with the user, if the identification times of the user are more than or equal to 2, a visiting signal is generated and sent to the mobile terminal of the user, if the identification times are less than 2, an abnormal personnel signal is generated and sent to the mobile terminal of the user, and meanwhile, the intelligent lock is unlocked.
5. The intelligent lock monitoring system based on ultra wideband technology according to claim 3, wherein the regulation module is further configured to receive a wake-up period and wake-up the intelligent lock in a standby state in the corresponding wake-up period, and the specific steps are as follows:
step one: after the range value of the wake-up time period is reached, opening the intelligent lock and being in a standby state, monitoring sensing through the infrared sensor in the standby state, sensing signal change by the infrared sensor when a user or an authorized user reaches the monitoring range of the infrared sensor, sending the sensed signal to the regulation and control module by the infrared sensor, obtaining the distance change between the two according to the signal change sensed by the received infrared sensor by the regulation and control module, judging whether the user is in a close state or not, and opening an unlocking interface by the intelligent lock when the signal change reaches a preset threshold value; simultaneously acquiring the temperature of the handle and the distance between the current position of the user and the intelligent lock, when the temperature of the handle is smaller than a low-temperature threshold value, matching the arrival time corresponding to the distance, heating the handle to the temperature set by the user in the arrival time by using a heating element arranged in the door handle, and simultaneously sending a prompt whether the indoor air conditioner is started to the mobile terminal of the user;
step two: collecting the ambient temperature in real time in the standby state process, correlating the temperature data with the monitoring data of the infrared sensor, and adjusting the sensitivity and the threshold of the infrared sensor when the temperature change reaches a preset threshold;
step three: acquiring sound information in a preset range according to a sound sensor arranged in the intelligent lock, associating the acquired sound information with an event of the image sensor when the sound value is about to reach a preset threshold value, matching the sound information in the preset range with the image information, and judging whether to open an unlocking interface by matching the walking sound of a person with the image information and performing associated analysis on signal change of the infrared sensor when the walking sound of the person is detected; and the sound sensor is also used for identifying abnormal sound information and triggering an alarm signal in the monitoring module, and simultaneously transmitting the video clip generated by the sound to the mobile terminal of the user.
