How smart home control systems work

Command launch fragmentation

         The command transmits a fragmentary function. It is important to receive various types of sensing signals through various types of sensing devices, and trigger control commands. Perhaps the human consciously remotely controls and manually triggers the corresponding transmitting intelligent device to retrieve control commands, for example: temperature and humidity sensors. Collecting temperature and humidity change data in the room, setting the triggering requirements for temperature and humidity changes according to requirements. When the temperature or humidity reaches the preset triggering requirement, the control command is retracted. When the temperature is high, the air conditioner starts to cool, when the temperature is low. The air conditioner starts to heat up. If the brightness sensor is installed, when the indoor light brightness is sufficient, the preset light is actively closed, and when the indoor light brightness is insufficient, the preset light is actively turned on. If the human body sensor is guarded, when the person is armed, it will be detected when someone is active, and the phone alarm will be triggered immediately. When the mode is not armed, the person will be activated, and the preset light will be activated actively. When no one is detected, the light will be actively closed. The completion of the above few scenes is through various sensors to actively trigger the intelligent control, and of course, it can indirectly manually trigger the control commands, for example, after various types of intelligent remote control, wall smart panel, and home LAN. Constraining a computer to trigger control commands indirectly, if the person is not indoors, can also control all the equipment in the room through telephone or INTERNET long-distance control.

         Command execution system

         For example, turning on or off the lights is important to complete through the smart panel. After receiving various control commands, the smart panel is parsed and decoded to drive the corresponding high-power drive circuit to turn the light control back on or off. In addition, the control of equipment such as electrical appliances and curtains is the same. When the digital curtain switch receives the control command, it immediately drives the corresponding circuit of the electric curtain motor to be turned on or off. Switch control. About the control of infrared home appliances, such as: air conditioners, televisions, DVDs, etc., after the body sensor is installed in the ceiling, the body sensor immediately forwards the control signal to the corresponding infrared command after receiving the control signal, like control Infrared control commands such as switching, playing, and pause of the DVD player. Regarding the completion of the security alarm function, when the digital security module receives the control command, it will switch to the corresponding voice signal and dial the preset telephone number alarm. Regarding the control intelligence of the background music, the digital audio and video center of gravity, after receiving the control command, immediately switches the external source circuit and starts playing the source. Therefore, when various types of complex scene commands are triggered, for example, the “cinema” scene key is triggered, then the corresponding command execution device fragmentation is decoded according to the received command and the control commands are executed together, therefore, the corresponding lights, appliances, curtains The background music starts with a one-sided preset task and reaches the preset scene effect.
