In some embodiments of the present invention, an intelligent home remote control socket system based on ZigBee is provided, which is shown in fig. 1 and 2 and includes a main control loop module and a remote controller module. As shown in fig. 1, the main control loop module includes a clock module 101, a first ZigBee CC 2530103, a power module 108, a home power grid AC220V 109, and a power control relay 104, where the power control relay 104 is connected to a home wall socket 105, the power control relay 104 is connected to a room electrical appliance 106, and the power control relay 104 is turned on or off under the control of the first ZigBee CC 2530103, so as to realize whether the home wall socket 105 can supply power to the room electrical appliance 106.

In the above scheme, with reference to the schematic circuit design diagrams shown in fig. 3 and fig. 4, the scheme of the present application adopts the idea of ZigBee CC2530 chip module standardization, that is, designs a universal CC2530 development board to realize communication between the remote controller and the socket.

As shown in fig. 4, the CC2530 development board is composed of a ZigBee bottom board and a CC2530 core board, and various sensors are compatible with the outside of the bottom board to adapt to different environments; the core board only has a CC2530 chip and an interface with the bottom board. An intelligent home remote control socket system based on ZigBee comprises a main control loop module and a remote controller module. The core module is designed by a power module, a wireless communication module, a debugging and downloading interface module, a reset circuit module and a remote controller power module.

The power module 108 of the main control loop module is to convert 220V ac power into 5V and 3.3V dc power to be supplied to the ZigBee module and the peripheral circuit. Cost and volume are preferred in intelligent home design, so that a resistance-capacitance voltage reduction scheme is selected to convert AC220V into DC 3.3V. As shown in fig. 5, 220V ac power is converted into 12V dc power through the rc step-down module, and then 5V dc power VCC is obtained through the capacitor filtering and the three-terminal integrated regulator LM7805, and finally stable 3.3V dc power is output through the regulator AMS1117, so as to provide working voltage for the first ZigBee CC 2530. The power control relay 104 includes a triode switch, which controls the conduction of a triode through the change of high and low levels of the output port of the first ZigBee CC2530, thereby controlling a triac and realizing the remote control of the home wall socket 105. The thyristor of the power control relay 104 has two forms of on and off. The bidirectional thyristor is equivalent to two thyristors with opposite polarities which are connected in parallel. The scheme is realized by adopting the MAC4DLM-1G bidirectional controllable silicon, the small-size surface mounting packaging DPAK of the MAC4DLM-1G bidirectional controllable silicon, the reliability and consistency of passivation death, four-quadrant triggering, blocking voltage of 600V, low-level triggering and maintaining characteristics of 4.0 ampere RMS of on-state current rated value of 93 ℃, epoxy of UL 94V-0 @0.125, the available characteristics of lead-free package, and the cost and safety consideration, the design adopts the MAC4DLM bidirectional controllable silicon chip with the highest current of 4A.
