[0065] Example 2

[0066] In the known technology, in the process of determining the identity of the visitor by the smart doorbell, the smart doorbell often only compares it with the pre-stored information, resulting in inaccurate visitor information broadcast by the smart doorbell and poor user experience. Therefore, in this embodiment, the first The first database is a local database, which is set in the smart doorbell, and the second database is a remote database, which is set in the cloud server. refer to figure 2 , figure 2 It is a flowchart of another embodiment of the visitor information reminder method in the present invention, the visitor information reminder method includes:

[0067] Step S201, detecting whether there is a visitor within the monitoring range of the smart doorbell;

[0068] Step S202, if it is detected that there is a visitor within the monitoring range, the characteristic information of the visitor is obtained, and the characteristic information includes biometric characteristic information that can determine the identity of the person and auxiliary characteristic information that can assist in determining the identity of the person;

[0069] Step S203, perform a preliminary comparison based on the visitor's biometric feature information and the local database, and quickly obtain the visitor's identity information according to the preliminary comparison result. The local database stores the identity information of the first preset person and the preset biometric feature information The corresponding relationship; wherein, the local database is established by pre-stored information of the user of the smart doorbell, the first preset person can be a fixed member of the family, friends, colleagues, relatives, etc., by pre-collecting the characteristics of the first preset person The information is used as the preset biometric feature information, and the identity information of the first preset person is obtained to establish a local database. For example, when a colleague visits, the smart doorbell installed outside acquires the feature information (including facial features) of the colleague , the feature information is sent to the user’s mobile terminal (such as a mobile phone) designated by the smart doorbell through the network, and the user enters the colleague’s identity information on the mobile terminal after viewing the feature information of the colleague, and the smart doorbell uses the feature information of the colleague as Preset biometric feature information, and store the preset biometric feature information and corresponding identity information in a local database for use in subsequent local comparisons;

[0070] Step S204, if the local comparison fails, a secondary comparison is performed based on the visitor's feature information and the remote database, and the visitor's identity information is obtained according to the secondary comparison result. The remote database stores the identity information of the second preset person and the preset The corresponding relationship of feature information is set, wherein, the identity information of the second preset person and the preset feature information are obtained by intelligent identification in advance according to the preset machine learning model of the smart doorbell;

[0071] Step S205, perform a user reminder operation according to the identity information of the visitor.

[0072] In this embodiment, the acquired visitor's feature information is divided into two types: biometric feature information and identity auxiliary feature information, and then local comparison is performed according to the biometric feature information and the local database to quickly obtain the visitor's identity information, and the local comparison If it fails, compare the visitor's characteristic information with the remote database to obtain the visitor's identity information, wherein the smart doorbell performs intelligent identification according to the preset machine learning model to obtain the identity of the second preset person used to establish the remote database Information and preset feature information, and finally perform user reminder operations according to the acquired identity information of visitors. Through the double data comparison with the local database and the remote database, the visitor's identity information can be quickly and accurately obtained and the user reminder operation can be performed, which effectively improves the user's experience of visitor identity reminder. In addition, if the comparison with the remote database fails, the comparison ends, and a comparison failure message is output to the user, prompting the customer that the visitor is not matched.

[0073] Example 3

[0074] In this embodiment, the method for detecting whether there are visitors within the monitoring range of the smart doorbell is specifically described:

[0075] refer to image 3 , image 3 The structural block diagram of the smart doorbell is shown as an example. The smart doorbell includes an outdoor unit and an indoor unit. The outdoor unit is generally installed at the outdoor door, and the indoor unit is generally installed indoors to send out a reminder ring to remind visitors of visitors. Specifically, the indoor unit includes a speaker 313 for playing voice, a storage module 310 for storing information, a second microphone module 312 for collecting voice, and a second main control module 311 used as the main control center of the indoor unit; And the outdoor unit includes the first main control module 309 used as the main control center of the outdoor unit, the first microphone module 308 for collecting voice, the camera 301 for collecting the monitoring video and images at the door, and the camera 301 for collecting images for the camera 301.

In some application scenarios, the trigger switch can be the touch button 303 or the doorbell button 305. Once a visitor touches the touch button 303 of the outdoor unit or presses the doorbell button 305 of the outdoor unit, it will trigger the smart doorbell to control the speaker 313 issued a prompt bell.

[0076] refer to image 3 There is a communication connection between the first main control module 309 and the second main control module 311, which can be a wired connection or a wireless connection, such as establishing a communication connection through WiFi. Here, the first main control module 309 and the second main control module The communication connection mode between the control modules 311 is not limited. In actual use, the first microphone module 308 and the second microphone module 312 can be realized by a microphone array, and the fill light 304 can be realized by a ring fill light, which can be a ring LED fill light. In addition, the human body infrared sensing module 306 is realized by a human body infrared sensor. The smart doorbell is equipped with a fingerprint identification module 307 and an iris image sensor 302 to open the door according to the user's fingerprint information and iris information. Therefore, the smart doorbell also includes an electronic lock module. The first main control module 309 confirms that the user is a preset After the user, the first main control module 309 controls the electronic lock module to unlock to realize opening the door.

[0077] Methods for detecting whether there are visitors within the monitoring range of the smart doorbell include but are not limited to the following methods:

[0078] The first method of detecting whether there is a visitor is by detecting whether the trigger switch is triggered. When the switch is triggered, it indicates that there is a visitor within the monitoring range of the smart doorbell. It can detect whether the smart doorbell has a pressing operation, and if the judgment result is yes, it is determined that the smart doorbell is triggered; for example, it is detected whether the doorbell button is pressed, and when the doorbell button is pressed, a button signal is output to the first main control module, Then it can be determined that the smart doorbell is triggered. It may also be determined whether the touch button of the smart doorbell is touched, and if the judgment result is yes, it is determined that the trigger switch of the smart doorbell is triggered.

[0079] The second method of detecting whether there is a visitor is to judge whether there is a human figure in the image or video captured by the camera of the smart doorbell, and when the human figure is judged by image processing and intelligent recognition technology, it indicates that there is a visitor.

[0080] The third way to detect whether there is a visitor is to judge whether the human body infrared sensor module of the smart doorbell outputs a signal. When the human body infrared sensor module outputs a signal, it indicates that it detects the presence of a human body, that is, there is a visitor.

[0081] The fourth method of detecting whether there is a visitor, by judging whether the smart doorbell has received the iris image sent by the iris image sensor and/or the fingerprint recognition result information sent by the fingerprint recognition module, when the smart doorbell receives the iris image and/or the fingerprint recognition result information When the information is displayed, it indicates that someone is performing iris recognition or fingerprint recognition, that is, a visitor has come to the door.

[0082] The fifth method of detecting whether there is a visitor is to detect whether there is a sound in the monitoring area of ​​the outdoor door by controlling the smart doorbell. If there is a sound, it indicates that there is a visitor.

[0083]The above provides a variety of visitor detection methods to increase the diversity of visitor detection methods; the above multiple methods can also be used for visitor detection at the same time to ensure the accuracy of visitor detection results.
