The invention discloses an inter-core communication method and device, a storage medium, a component and a chip, and relates to the technical field of chips, the inter-core communication method is executed by a first communication system, and the inter-core communication method comprises the following steps: responding to a condition that a first inter-core communication component in the first communication system meets a power-off condition, and sending a power-off notification to a second communication system; and according to feedback information of the second communication system on the power-off notification, determining whether to power off the first inter-core communication component. Compared with the prior art, the inter-core communication component in the communication system can enable another system to evaluate whether power-off can be carried out or not in a power-off notification mode before power-off, so that whether the first inter-core communication component is powered off or not is determined according to the returned evaluation result; therefore, the situation that the inter-core communication component in one system is powered off and the other system needs to carry out data interaction with the system is avoided, data transmission between different communication systems is guaranteed, and power-on and power-off safety of the inter-core communication components between the different systems is also guaranteed.

The present application relates to the technical field of wireless communication, and in particular to a smart water meter supporting dual-mode communication and a data synchronization method thereof. The method comprises: obtaining communication jam values of a plurality of smart water meters, wherein the communication jam value is used to represent the communication jam degree between the corresponding smart water meter and the management platform; performing screening processing based on the communication jam values of each smart water meter to determine a first smart water meter and a second smart water meter; controlling the first smart water meter to transmit data to the management platform in a first communication mode; determining a first coordination water meter among the plurality of second smart water meters, and controlling the first coordination water meter to transmit data of all second smart water meters to the management platform, wherein the first coordination water meter is one of the plurality of second smart water meters, and the data of the second smart water meter is reported to the first coordination water meter in a second communication mode. The present application can improve the reliability of data synchronization.
