Abstract: The present invention provides a micro-controller, a processing method and device for power line carrier signal reception, where the method includes: an analog mixer mixes received power line carrier signals, an analog filter filters the mixed power line carrier signals, an analog-to-digital converter converts the filtered signals, a digital mixer mixes converted signals, a digital filter filters the mixed signals and a digital demodulator demodulates the filtered signals to obtain base band data. The present invention also provides a corresponding device and a micro-controller including the device. The technical solution of the present invention can modulate the carrier signals of any frequency to a fixed frequency through two-stage frequency mixing, so that demodulation of power line carrier signals with any frequency is possible.

Abstract: A receiving circuit, a transmitting circuit, a micro-controller, and a method for power line carrier communication. The receiving circuit includes: an analog amplifier, a receiving filter, an analog-to-digital converter, a digital mixer, a digital filter, and a digital demodulator connected successively. The transmitting circuit includes: a digital modulator, a gain controller, a digital-to-analog converter, a transmitting filter, and a transmitting amplifier connected successively. The micro-controller includes a central processor and the receiving circuit or the transmitting circuit. The method for power line carrier communication can be implemented based on the receiving circuit or the micro-controller.

Abstract: The present invention discloses container that is structured with framing bars linked with mesh between the framing bars. The container further includes framing bar connectors and each of the framing bar connectors connecting and holding each of the framing bars at a fixed orientation relative to another interconnected framing bar connected through each of the framing bar connectors. In a specific containing apparatus, each of the framing bar connectors includes a first U-shaped trench for adapting and holding a first framing bar and at least a second U-shaped trench for adapting and holding a second framing bar at a fixed orientation relative to the first framing bar.
