Description

Technical Field

[0001] The invention relates to a transmission device, in particular to a single-coil carrier amplitude modulation type multi-band signal and energy synchronous transmission device. Background Art

[0002] With the development of the Internet of Things, some intelligent systems need to be powered in real time when they are running, and also need to realize real-time two-way transmission of signals between external controllers and such intelligent systems to realize intelligent control. For example, in the intelligent system used to control the temperature of a fish tank in cooperation with a thermostat, the intelligent system is installed on the fish tank. While powering the intelligent system, the thermostat not only needs to obtain the temperature of the fish tank, but also needs to control the intelligent system according to the temperature of the fish tank, that is, the thermostat needs to send a temperature acquisition control signal to the intelligent system. After receiving the temperature acquisition control signal, the intelligent system needs to send the detected fish tank temperature (corresponding to the operating state) to the thermostat. The thermostat generates a temperature adjustment control signal according to the received fish tank temperature to control the intelligent system, adjust the temperature of the fish tank or maintain the temperature of the fish tank, that is, two-way transmission of signals needs to be realized between the thermostat and the intelligent system.

[0003] At present, the power supply of such intelligent systems and the bidirectional transmission of signals between such intelligent systems and external controllers are achieved by installing a full-duplex power line communication device at such intelligent systems. The existing full-duplex power line communication device can transmit energy to such intelligent systems on the one hand to power all energy-consuming loads inside such intelligent systems, and on the other hand, it can receive control signals transmitted by external controllers and output them to such intelligent systems after demodulation, so that the central processor of such intelligent systems can change the operating status of such intelligent systems and obtain the operating status of such intelligent systems and output it to the external controller. However, the existing full-duplex power line communication device uses a wired method to complete the above functions, which makes the lines of such intelligent systems complex, difficult to install and maintain, and makes it difficult to adopt a modular design concept at the beginning of the design, which greatly increases the development cycle. Summary of the invention
