The invention discloses a double-frequency narrow-band receiving method, system and equipment based on time division multiplexing and a medium, which are applied to a receiving circuit, the receiving method realizes time division receiving of double-frequency-band narrow-band signals through a time division multiplexing method, and double frequency bands are divided into a first frequency band and a second frequency band. A large amount of power consumed when the receiving circuit cannot receive node wireless signals for a long time can be reduced, the receiving circuit can be synchronized with the node signals when the node signals can be received, and the service life of communication equipment can be greatly prolonged.
Description
technical field [0001] The present invention relates to the field of wireless communication, in particular to a dual-frequency narrowband receiving method, system, device and medium based on time division multiplexing. Background technique [0002] SG-LongRange is a local area network wireless communication technology, which not only supports the 230MHz power wireless private network frequency band, but also is compatible with the 510MHz civilian metering instrument frequency band. The dual-band narrowband receiving method refers to the time-division multiplexing method to receive 230MHz and 510MHz narrowband signals. , to meet the technical requirements of SG-LongRange wireless communication and overcome the problem of scarcity of spectrum resources in the 230MHz frequency band. [0003] The received signal includes 230MHz and 510MHz dual-band narrowband signals, and a time synchronization mechanism is required: every time the receiver receives the wireless signal of the no...
