Embodiment 1
[0036] Such as figure 1 Shown, a kind of Internet of Things node energy-saving method is characterized in that, comprises the following steps:
[0037] S1: Determine whether the node device is in a dormant state or a working state;
[0038] Of course, before this step, the node device needs to be powered on so that the entire system is in a working or dormant state to obtain the judgment result;
[0039] S2: If the judgment result is that the node device is in working state,
[0040] The data information of the periodic message is loaded through the capacity gap of the working message, so that the data information of the periodic message is sent to the server 3 through the gateway device together with the working message by using the capacity gap;
[0041] In this step, when the node device is in the working state, the capacity gap of the working message loads the data information method of the periodic message including the following steps:
[0042] S2.1: Fragment each wor...
Embodiment 2
[0060] Such as figure 2 As shown, this embodiment is similar to Embodiment 1, the difference is that this embodiment is an IoT node energy-saving system that adopts an IoT node energy-saving method. This embodiment takes a smart home network as an example for specific description. The IoT node energy-saving system of the embodiment includes a node device, a gateway device, and a server 3. The node device transmits the work message sent by the node device in fragments and can carry a periodic fragment message at the end of the work message. The MAC layer of the text data information communicates with the gateway device, and the gateway device is connected to the server 3 through the wireless network.
[0061] Further, the MAC layer is connected with a capacity gap calculation unit for calculating the size of the capacity gap at the end of each working message, and the capacity gap is used to accommodate the data information of the periodic fragmented message, and the regular f...
Embodiment 3
[0064] This embodiment is similar to Embodiment 1, except that the node device and the gateway device in this embodiment use the Zigbee protocol for communication connection.
[0065] The ZigBee protocol adapts to the requirements of low cost, low energy, and high fault tolerance of wireless sensors. The basis of Zigbee is IEEE 802.15.4, but IEEE only deals with low-level MAC layer and physical layer protocols. Therefore, the Zigbee Alliance extends IEEE to its network Layer protocols and APIs have been standardized; Zigbee is a short-distance, low-rate wireless network technology, mainly used for short-distance wireless connections, because it has its own protocol standards, it can coordinate among thousands of tiny sensors Realize communication, have better compatibility, and meet the communication requirements between more devices.
[0066] The energy-saving method of the Internet of Things node of the present invention utilizes the capacity gap of the working message to tr...
