This invention belongs to the field of communication technology and discloses a low-power data communication method and system for electricity meters based on a CAT1 module. The electricity meter collects metering data and event data, encapsulates them into data frames with serial numbers, and writes them into a transmission queue. When a queue threshold, alarm threshold, or time threshold is met, a communication session is established, waking up the CAT1 module to send batch uplink data containing a session identifier and batch sequence start and end numbers. The platform returns confirmation information, including a set of confirmed sequence intervals, missing data frame identifiers, and downlink pending transmission identifiers. The terminal retransmits missing frames within the session based on this information, opens a listening window only when a downlink command exists, deletes confirmed frames after the session ends, enters low-power mode, and persists the queue state to support power-off resume transmission.

According to the information transmission method and device for vehicle monitoring and the computer readable medium provided by the embodiment of the invention, an authentication mechanism of fingerprint information is constructed based on hardware information, and the fingerprint information is sensitive to changes of hardware such as a mainboard and a network card; therefore, it is ensured that only the authenticated vehicle-mounted equipment can perform heartbeat interaction with the server-side equipment and report data, the authenticity of a data source is ensured, data security risks caused by equipment cloning and the like can be prevented, a heartbeat interaction mechanism and a data reporting process are optimized, and the data reporting efficiency is improved. The problems that in an existing scheme, a large number of network resources are consumed in an unstable network environment, resource waste is caused, and data loss is prone to occurring are effectively solved.

The invention discloses an icing monitoring terminal module interconnection communication method, system and device based on data fusion, and a medium, and belongs to the technical field of power monitoring, and the method comprises the steps: collecting the monitoring data of a plurality of sensors; performing fusion processing on the monitoring data according to a data fusion rule to obtain an icing risk assessment result; determining a communication strategy according to the icing risk assessment result, wherein the communication strategy comprises a communication mode, a data transmission frequency and a transmission data type; executing data transmission according to the communication strategy; monitoring the state of the communication link, and when the communication link is abnormal, switching to a standby communication link according to the icing risk assessment result and the state information of the available communication link; and adjusting the data transmission frequency according to the power state. According to the method, the icing risk level is calculated by fusing the multi-source data of the tension, the inclination angle, the weather and the image and introducing the icing potential function, and the communication strategy is dynamically adjusted based on the risk level, so that the energy consumption waste in the low-risk time period is avoided, and the reliable information transmission in the high-risk time period is ensured.
