The invention provides a method for highly-reliably constructing a dynamic Ad-Hoc Network of multiple smart household devices. The method comprises: acquiring a route table between a central control device and sub devices and prestored time stamps of the sub devices; acquiring the current time stamps of the sub devices; updating the route information of a sub device if the current time stamp of the sub device is more than the prestored time stamp of the sub device; establishing a dynamic Ad-Hoc Network according to the sub devices, the central control device, and the updated route table. The method solves a problem of poor system expansibility and low reliability in a multiple household device control process, and may timely discover communication conditions between the sub devices and between the sub devices and the central control device, automatically identifies the completely-disabled sub devices, enables the completely-disabled sub devices to be repaired by repairers, dynamically updates the route tables of sub devices in poor communication, and allocates other routes to the sub devices in poor communication in order to guarantee the communication control of the smart household sub devices in a house to the utmost extent.
Description
technical field [0001] The invention relates to the technical field of system implementation and application of multi-smart home, in particular to a method for constructing a dynamic ad hoc network of high-reliability multi-smart home devices. Background technique [0002] Low-voltage power carrier communication technology (PLC) uses existing power lines to transmit data through carrier technology. Since the interference problem of low-voltage power line carrier transmission channel is the main obstacle restricting the development and popularization of low-voltage power line carrier communication, and the Orthogonal Frequency Division Multiplexing (OFDM) modulation technology has the characteristics of strong anti-interference and anti-fading capabilities. Multiplexing (OFDM) modulation technology chip design power carrier data transmission module can better overcome the defects of strong interference and strong attenuation of power lines. Low-voltage power line carrier com...
