The intelligent devices include but are not limited to visual access control, security cameras, intelligent household appliances (air conditioners, electric cookers, refrigerators and electric heaters), environment monitoring sensors (temperature and humidity sensors, PM2.5 sensors, gas sensors) and other devices.
The data processing module is used for receiving the operation parameter information sent and received by the intelligent equipment, synthesizing the operation parameter information through the application data stored in the data storage module and generating a second audio and video signal. The parameter information includes at least one of a video parameter, an audio parameter, and a device status parameter (temperature, humidity, time information, status information, etc.) when the smart device is operating, but the premise is that the smart device needs to establish a connection through a WiFi communication module of the gateway master controller and send the parameter information when operating to the gateway master controller.
For example, the intelligent device may be a lamp in a living room, the lamp establishes communication connection with the intelligent gateway device, the lamp has a portrait detection function, and when no person is detected in the living room, a reminder may be sent to the intelligent gateway device, where the reminder may specifically include parameter information of the lamp, such as a warm light mode, a video animation indicating whether the person is detected and whether the person is turned off. For example, if the temperature of the electric heater is set too high, audio and video information related to the electric heater can be called from the data storage module, and temperature reminding is generated according to parameter information (temperature regulation), such as reminding of the temperature being too high or too low. After the second audio and video signal is generated in the mode, the gateway main controller sends a signal switching instruction to the HDMI switching controller through the RS485 communication interface.
As shown in fig. 5, a flow chart of switching video signals for the intelligent gateway device.
After the intelligent gateway equipment is powered on, the output signal is automatically switched into a first audio and video signal, namely the content of the set top box equipment of the television player indicates that a user watches television. When the gateway main controller detects a request instruction, the gateway main controller indicates that the monitoring equipment detects a human image or someone triggers the access control equipment, namely someone knocks the door; or detecting that the household intelligent equipment needs to be adjusted and reminded, and at the moment, the gateway main controller generates a second audio and video signal based on the parameter information sent by the intelligent equipment, or calls a monitoring picture of the monitoring equipment and sends a reminder to the television. And when the user is confirmed, the gateway main controller sends a signal switching instruction to the HDMI switching controller through the RS485 control bus. And when the HDMI switching controller receives the control instruction, the HDMI switching controller automatically switches the output signal into a second audio/video signal. The sending reminding can be set according to users, for example, special intelligent equipment such as monitoring equipment, an electric heater and a range hood can directly switch audio and video signals, and is specifically set according to user wishes.
Further, after the transmission of the second audio/video signal of the gateway main controller is finished, the HDMI switching controller automatically switches back to the first audio/video signal. For example, when the second audio/video signal is a picture shot by the monitoring device, and when the user opens a door or the picture displays a preset time, the gateway main controller sends a signal switching instruction again to switch the picture back to the picture of the set-top box device.
