Claim 7:
8. An Internet of Things data transmission method, comprising a downlink transmission step and an uplink transmission step, wherein the downlink transmission step comprises:
obtaining a metering task;
performing packet format processing on the metering task according to a first packet format and a communication protocol of a target meter to generate first downlink data, the first downlink data comprising a first packet generated from the first packet format, a communication protocol packet of the target meter and the metering task; and
delivering the first downlink data to a concentrator, so that the concentrator obtains second downlink data by parsing and sends the second downlink data to the corresponding target meter, wherein the second downlink data comprises the communication protocol packet of the target meter and the metering task; and
the uplink transmission step comprises:
obtaining a second uplink data uploaded by the concentrator;
the second uplink data comprising the first packet generated from the first packet format, the communication protocol packet of the target meter and a metering task result,
the first packet format comprises: a number of tasks in a present frame and a first data unit format for each metering task,
the first data unit format comprises at least one of the following: a task number, a task flag, a forwarding priority, a report flag, a storage depth, a task start time, a task cycle attribute, a task cycle interval, a task end time, a communication protocol type, a rule option, an estimated task answer length, a task packet length and task packet content;
and the first data unit format comprises at least the forwarding priority.
