[0084] Figure 1 An exemplary system architecture 100 is shown to which some embodiments of the monitoring device 200 of the present application may be applied.

[0085] like Figure 1 As shown, the system architecture 100 may include terminal devices 101, 102, a server 103, and networks 104, 105, 106. The network 104 is used to provide a medium for a communication link between the terminal device 101 and the server 103, the network 105 is used to provide a medium for a communication link between the terminal device 102 and the server 103, and the network 106 is used to provide a medium for a communication link between the terminal device 101 and the terminal device 102. The networks 104, 105, 106 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0086] The user can use the terminal device 101 to interact with the server 103 through the network 104, or use the terminal device 102 to interact with the server 103 through the network 105, or the terminal device 101 can interact with the terminal device 102 through the server 103, or the terminal device 101 can interact with the terminal device 102 through the network 106 to receive or send messages, etc. Various client applications can be installed on the terminal devices 101 and 102, such as video remote monitoring applications, smart home management platform software, etc.

[0087] Terminal devices 101 and 102 can be hardware or software. When terminal devices 101, 102, and 103 are hardware, they can be various electronic devices, including but not limited to smart phones, tablet computers, wearable devices, vehicle-mounted devices, augmented reality (AR) / virtual reality (VR) devices, ultra-mobile personal computers (UMPC), netbooks, personal digital assistants (PDA), e-book readers, MP3 (Moving Picture Experts Group Audio Layer III, Moving Picture Experts Compression Standard Audio Layer 3) players, MP4 (Moving Picture Experts Group Audio Layer IV, Moving Picture Experts Compression Standard Audio Layer 4) players, laptop computers, desktop computers, smart electric meters, smart water meters, smart cat eyes, gateways and other electronic devices. When terminal devices 101 and 102 are software, they can be installed in the electronic devices listed above and used as clients. It can be implemented as multiple software or software modules (for example, to provide distributed services), or it can be implemented as a single software or software module. The embodiments of the present application do not impose any limitation on the specific type of electronic device.

[0088] The server 103 may be a server that provides various services, such as a background server that supports the terminal devices 101 and 102. In response to receiving a doorbell information request sent by the terminal device 101, the background server may forward the request to the terminal device 102. After the terminal device 102 receives the doorbell information request, it returns a real-time video call instruction, and the server 103 then forwards the real-time video call instruction to the terminal device 101. The terminal device 101 receives and executes the real-time video call instruction, and at this time, the server 103 provides services for the real-time video call.

[0089] It should be noted that the server can be hardware or software. When the server is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or it can be implemented as a single server. When the server is software, it can be implemented as multiple software or software modules (for example, used to provide distributed services), or it can be implemented as a single software or software module. No specific limitation is made here.

[0090] It should be noted that the monitoring device 200 provided in the embodiment of the present application is generally the terminal device 101 in the above-mentioned system architecture 100.

[0091] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0092] Continue to refer Figure 2 , which shows a schematic diagram of the structure of an embodiment of a monitoring device 200 according to the present application Figure 1 In this embodiment, the monitoring device 200 may be a smart device, such as Figure 1 The terminal device 101 is shown.

[0093] like Figure 2 As shown, the monitoring device 200 includes a sub-machine 210, a host 220 and a connecting line 230, the sub-machine 210 includes a camera unit 211, the host 220 includes a first control chip 221, a display screen 222 and a first data interface 223 that supports forward and reverse plugging, the first control chip 221 is respectively connected to the display screen 222 and the first data interface 223, the connecting line 230 includes a first terminal and a second terminal, the connecting line 230 is used to connect the host 220 and the sub-machine 210, the first terminal of the connecting line 230 includes a second data interface 231 that is plugged in and out with the first data interface 223 on the host 220, and the second terminal of the connecting line 230 includes a signal connector 232 connected to the camera unit 211 of the sub-machine 210.

[0094] The above-mentioned monitoring device 200 is an intelligent device composed of multiple devices that need to be connected by a connecting line 230, and can be used to realize functions such as intelligent monitoring. The first terminal of the connecting line 230 adopts a second data interface 231 that supports positive and negative plugging to connect with the first data interface 223 of the host 220, and the second terminal of the connecting line 230 adopts a signal connector 232 to connect with the slave 210. This connection method is very simple and convenient, and effectively avoids the situation where the user damages the interface or connector due to misoperation or unfamiliarity with circuit connection during the assembly process of the intelligent device.

[0095] In some exemplary embodiments, the inventors of the present application have found through research that, considering that the data interface supports pin customization in different devices, if a standard data interface is connected to a customized data interface, it is easy to cause damage to the smart device or the data interface. Figure 2The first data interface 223 of the host 220 in the illustrated embodiment may use a TYP-C interface that supports forward and reverse plugging. TYP-C is a standard hardware interface with a total of 24 pins. Each pin has a standard definition, such as a power pin, a USB signal transmission pin, etc. Since the Type-C interface supports double-sided insertion and does not require precise alignment, its 24 pins can also be used in products as a signal transmission interface in a customized manner. However, if a custom Type-C pin is used, it is necessary to consider that the user may use a standard Type-C charging head to connect it, resulting in damage to the product. Therefore, for the application of such custom Type-C pins, the interface needs to be protected.

[0096] See also Figure 3 , showing a schematic diagram of the structure of an embodiment of a monitoring device 200 according to the present application Figure 2 In this embodiment, Figure 2 The first data interface 223 of the embodiment shown is a female interface that supports forward and reverse plugging, and the second data interface 231 is a male interface that supports forward and reverse plugging. Specifically, the female interface and the male interface can be a TYP-C female and a TYP-C male, respectively. Figure 3 As shown, the host 220 of the monitoring device 200 also includes a second control chip 224, the second control chip 224 is used to connect the first control chip 221 and the first data interface 223, the second control chip 224 includes a switch circuit unit 2241 that triggers the control of the first control chip 221 and the first data interface 223 to disconnect or close the connection; the first data interface 223 includes a plurality of pins, the first control chip 221 at least includes a detection circuit unit 2211 and a control circuit unit 2212, the detection circuit unit 2211 is used to detect at least one pin level value in the first data interface 223, the detection circuit unit 2211 is connected to at least one pin in the first data interface 223, the control circuit unit 2212 is used to control the switch circuit unit 2241 to disconnect or close according to at least one pin level value, and the control circuit unit 2212 is connected to the switch circuit unit 2241 and the detection circuit unit 2211.

[0097] This embodiment creatively adopts the characteristic that the level value of one of the pins of the first data interface 223 may be different depending on whether the correct second data interface 231 is inserted, or the level value of one of the pins of the first data interface 223 has a specific level value only when the correct second data interface 231 is inserted. The detection circuit unit 2211 is used to detect the level value of one of the pins of the first data interface 223. When the level value changes, the switch circuit unit 2241 in the second control chip 224 disconnects or closes the electrical connection between the first control chip 221 and the first data interface 223, thereby protecting the smart device from damage due to the insertion of the wrong second data interface 231.

[0098] Specifically, the above-mentioned first control chip 221 is generally the main control chip of the host 220, and the detection circuit unit 2211 and the control circuit unit 2212 can be implemented as integrated circuit units. Therefore, when the first control chip 221 is the main control chip of the host 220, the detection circuit unit 2211 and the control circuit unit 2212 can be implemented as integrated circuit units in the first control chip 221, or they can be implemented as independent integrated chips implemented by integrated circuit units connected to the first control chip 221.

[0099] In some exemplary embodiments, see Figure 4 , shows a schematic structural diagram of an embodiment of a monitoring device 200 neutron machine 210 according to the present application, such as Figure 4 As shown, the sub-machine 210 may also include a third control chip 212, which is used to control the camera unit 211 to collect image information, and the third control chip 212 is connected to the camera unit 211; in addition, the sub-machine 210 may also include at least one of a doorbell button 213, a microphone 216 and a sensor 214, and the doorbell button 213, the microphone 216 and the sensor 214 are respectively connected to the third control chip 212, wherein the doorbell button 213 is used to trigger the doorbell sound and the display screen 222 displays the image information obtained by the camera unit 211, the microphone 216 is used to collect sound information, and the sensor 214 is used to trigger the camera unit 211 to obtain image information.

[0100] Specifically, the third control chip 212 in the slave 210 can be used as the control chip of the slave 210, and is used to control the slave 210 to work according to the doorbell button 213, the sensor 214 and the triggering signal of the first control chip 221 in the slave 210. For example, when the sensor 214 connected to the third control chip 212 is triggered, the third control chip 212 can directly control the camera unit 211 to obtain image information. In this way, by setting the third control chip 212 in the slave 210 in this embodiment, the operating efficiency of the monitoring device 200 can be improved.

[0101] Specifically, the doorbell button 213 is used to trigger the doorbell sound, which can be implemented by the doorbell circuit generating the doorbell sound according to the instruction triggered by the doorbell button. It should be understood that the doorbell circuit can be implemented as a dedicated integrated circuit module or an analog circuit structure, and the doorbell circuit includes a speaker for sounding. The present application does not limit the specific implementation of the doorbell circuit.

[0102] In an exemplary implementation scenario, the doorbell circuit can be connected to the first control chip 221 of the host 220, or to the third control chip 212 of the slave 210. For example, if the doorbell circuit is connected to the first control chip 221, when the doorbell button 213 is triggered, the first control chip 221 can directly receive the instruction of the doorbell button being triggered or the instruction of the doorbell button being triggered forwarded by the third control chip 212, and then control the doorbell circuit to play the doorbell sound. For another example, if the doorbell circuit is connected to the third control chip 212, when the doorbell button 213 is triggered, the third control chip 212 can receive the instruction of the doorbell button being triggered, and then control the doorbell circuit to play the doorbell sound.

[0103] Specifically, the sensor 214 may include any one of an infrared sensor and a proximity sensor. The sensor 214 may be connected to the third control chip 212 in the slave 210, or may be connected to the first control chip 221 in the host 220. If the sensor 214 is connected to the first control chip 221, then when the sensor 214 is triggered, the first control chip 221 notifies the third control chip 212 to control the camera unit 211 to collect image information; if the sensor 214 is connected to the third control chip 212, then when the sensor 214 is triggered, the third control chip 212 controls the camera unit 211 to collect image information. For example, when someone approaches the slave 210, the third control chip 212 controls the camera unit 211 to collect image information.

[0104] In some exemplary embodiments, combined with Figure 4 The slave machine 210 further includes a third data interface 215 for connecting to a signal connector 232 at a second terminal of the connecting line 230 . The third data interface 215 is connected to the third control chip 212 .

[0105] Specifically, the signal connector 232 of the second terminal of the connecting line 230 may be a conductive contact sheet, and the signal connector 232 may specifically include but is not limited to a gold finger, a conductive pin or a data interface. Correspondingly, the third data interface 215 is an interface corresponding to the gold finger, the conductive pin or the data interface. Here, the two terminals of the connecting line 230 are set to different interface structures, so that when the user is installing the smart device, he can clearly know that one of the terminals of the connecting line 230 is used to connect the host 220 or the slave 210, avoiding the situation where the same interface is used and the user cannot distinguish. .

[0106] In some exemplary embodiments, see Figure 5 , showing a schematic diagram of the structure of a host 220 of a monitoring device 200 according to an embodiment of the present application Figure 2 ,like Figure 5 As shown, the host 220 may also include a wireless communication module 225, which is used to wirelessly send prompt information including at least image information obtained by the camera unit 211 to the client and receive a real-time video call instruction initiated by the client, wherein the wireless communication module 225 is connected to the first control chip 221, and the client can be Figure 1 The terminal device 102 shown, of course, the prompt information can also include information that the doorbell button 213 is triggered and sound information collected by the microphone 216 on the slave 210. In this embodiment, the host 220 can interact with external devices through the wireless communication module 225, thereby realizing functions such as remote monitoring of the host 220.

[0107] For example, in an exemplary implementation scenario, the wireless communication module 225 in the host 220 can be implemented as follows: when the first control chip 221 in the host 220 receives an instruction to trigger the doorbell button 213, it executes the sending of the doorbell triggered prompt information containing at least the image information obtained by the camera unit 211 to the client through the wireless communication module 225, so that the user using the client can promptly understand the situation in front of the sub-machine 210; at the same time, the user on the client can also choose to initiate a real-time video call or real-time voice call request to the host 220 through the client. After the host 220 receives the real-time video call or real-time voice call request through the wireless communication module 225, the host 220 establishes a communication connection with the client, and then obtains the real-time image information collected by the camera unit 211 in the sub-machine 210 and the voice information collected by the microphone 216 to interact with the client to realize the real-time video call or real-time voice call.

[0108] See also Figure 6 , shows a product implementation structure diagram of an embodiment of the monitoring device 200 provided by the present application, Figure 6 The smart devices shown in Figure 2-Figure 5The implemented product of the monitoring device 200 shown is, for example, a smart cat's eye.

[0109] like Figure 6 As shown, the host 220 of the monitoring device 200 is used to be installed in the door 300 (the installation structure of the host 220 in the door 300 is not shown in the figure), the slave 210 is used to be installed outside the door 300, and the connecting line 230 is used to connect the host 220 and the slave 210.
