There are 4 modes to choose from at home, out, sleeping, and manual; the home appliance module is used to output through the 485 The interface transmits signals to the digital indoor unit, and controls the home appliances through the digital indoor unit, including 8 modes such as meeting, dining, sleeping, at home, rising at night, outing, leisure, and others; network camera control module , Used for other terminal devices to feed back the video information shot by the network camera to the terminal device after logging in through the router. The terminal device is a smart phone or PC computer that meets the system specifications. The digital indoor unit 102 includes a main control CPU 1, a display unit 2, a microphone 3, a speaker 4, a key control unit 5, an audio and video processing unit 6, and a storage unit 7. The display unit 2, the microphone 3, the speaker 4, the key control unit 5, the audio and video processing unit 6, and the storage unit 7 are all connected to the main control CPU 1, and the digitalization The indoor unit also includes an Ethernet interface unit 8 connected to the main control CPU1, and a wireless communication transceiver unit 9. The main control CPU1 is connected to the smart home network converter 104 through the Ethernet interface unit 8, and can be The controlled device is controlled through the wireless communication transceiver unit 9. The main control CPU1 includes: a management and configuration module for configuring user setting information and configuring communication addresses and establishing communication with the network device through the Ethernet interface unit Connection; home security control module, used to arm and disarm the security equipment in the defense zone, and transmit the trigger alarm information after the arming is successful to the speaker and external alarm or management center machine; home appliance control module, used for home appliances Set up the device and control the on and off of the home appliance through the wireless communication transceiver unit; the intercom visual control module is used to perform visual intercom with the door phone or to communicate with other users' indoor units in a network in the same cell Make calls, control the door phone to unlock, monitor and take pictures through the door phone, or talk to the management center; the information query module is used to delete and read the relevant information issued by the management center; the do not disturb module is used to Perform the do-not-disturb function that the indoor unit does not ring when it is called; the emergency call module is used to send alarm information to the speaker or external alarm or the management center machine under special circumstances; the elevator call module is used to call The elevator connected to the indoor unit stays on this floor; the community repair module is used to send water, electricity, and gas information to the management center machine, which will be processed after confirmation by the management center machine. The storage unit includes at least one of FLASH flash memory or SDRAM card, the wireless communication transceiver unit is a 2.4G wireless module or a 433M wireless module or a WIFI wireless module or a Bluetooth module, and the digital door phone 103 includes a master CPU, camera, keyboard, touch screen, microphone, speaker, Ethernet interface module, said camera, said keyboard, said touch screen, said microphone, said speaker, said Ethernet interface module and said main control CPU The main control CPU is connected to the switch 101 through the Ethernet interface module. The digital indoor unit 102 is set up through the management and configuration module, enters the network address and the building unit and room number, and establishes a connection with the digital door phone 103. In addition, you can also set your own mobile phone number. When the user is not at home, he will send text messages and pictures of the visitor to the preset mobile phone number. When the visitor calls the digital indoor unit 102 on the digital door phone 103, he enters the intercom video Module, the speaker 4 sounds a bell, and the display unit 2 automatically displays visitor influence. If the user is not at home or no one answers, the bell will automatically stop playing for a preset time and take a picture, and the picture information will be saved to the storage The unit 7 is easy to check. When the user answers the call, he can talk with the visitor or directly press the unlock button to unlock the door lock controlled by the digital door phone 103. When the user wants to know the door unit at home, he can press the monitor button to open The camera of the digital door phone 103 monitors the door unit. In addition, you can directly enter the same cell under this module to get the user's building unit number and room number in the same network, call the other party and make a conversation; According to the actual situation, the home security module can be used to control the arming and disarming of the indoor security equipment. The security equipment includes door magnets, window magnets, alarms, smoke detectors, gas detectors, etc. The trigger information will be It is transmitted to the speaker 4 and external alarm or property management. If it is triggered by mistake, click any position on the screen or press any key to stop the alarm; the home appliance control module can communicate with the digital indoor unit 102 wirelessly according to the actual situation. Communication-connected home appliances are controlled. The home appliances include lights, TVs, curtains, air conditioners, etc., which are generally not directly controlled, but indirectly controlled through smart switches or smart air conditioning conversion controllers.

[0031] Compared with the prior art, the digital indoor unit of the present invention integrates video intercom, home control, and security control, which is easy to install and use, saves the user's cost, and can function as monitoring and taking pictures. , The related functions are realized through TCP/IP networking, and the digital signal is used for transmission, so that the audio, video and control signals of the smart home security system are improved. Moreover, the smart home security system can have an online upgrade function, and the system version The network update makes the system maintenance more convenient. More importantly, when the user is not at home, he can quickly and conveniently transmit signals to the digital indoor unit through the smart home network converter through the mobile phone terminal, and the digital indoor performs control Command to implement remote control of household appliances in the user's room, and remote monitoring can also be achieved through the network camera.
