7. The gas meter query method based on the compound IoT according to claim 6 , wherein the method further comprises:
sending, by the management platform, when the gas balance of the second gas meter is less than the set threshold, fourth prompt information to at least one of a plurality of service sub-platforms; and
sending, by one of the service sub-platforms that receives the fourth prompt information, the fourth prompt information to a user sub-platform corresponding to the second gas meter.

8. The gas meter query method based on the compound IoT according to claim 7 , wherein the method further comprises:
estimating, by the management platform, when the gas balance of the second gas meter is less than the set threshold, a remaining gas usage time limit of the second gas meter according to an average gas consumption rate of the second gas meter, and sending the fourth prompt information to at least one of the plurality of service sub-platforms, where the fourth prompt information includes the remaining gas usage time limit.

9. An IoT system comprising:
a first gas meter of a plurality of gas meters, configured to read data information of a gas card, determine whether the data information of the gas card corresponds to a second gas meter that is different from the first gas meter, and send the data information to a management platform via a sensor network platform based on the determination that the data information of the gas card corresponds to the second gas meter.

10. The IoT system according to claim 9 , wherein the management platform is configured to send a first control signal to the second gas meter via the sensor network platform to instruct the second gas meter to send first prompt information.

11. The IoT system according to claim 10 , wherein second prompt information is sent to at least one of a plurality of service sub-platforms; and
one of the service sub-platforms that receives the second prompt information sends the second prompt information to a user sub-platform corresponding to the second gas meter.

12.
