Abstract

The present invention provides a gas meter query method based on a compound Internet of Things (IoT) and an IoT system, and relates to the field of the IoT. The method includes: sending, by the first gas meter of a plurality of gas meters, when reading the data information corresponding to the second gas meter, the data information to the management platform via the sensor network platform; sending, by the management platform, the first control signal to the second gas meter via the sensor network platform, so that the second gas meter sends the first prompt information; sending the second 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 second prompt information, the second prompt information to the user sub-platform corresponding to the second gas meter.

First claim

receiving, by a management platform via a sensor network platform, data information of a gas card from a first gas meter of a plurality of gas meters, wherein the data information is sent by the first gas meter based on a determination that the data information of the gas card corresponds to a second gas meter of the plurality of gas meters; and
sending, by the management platform, a first control signal to the second gas meter via the sensor network platform to instruction the second gas meter to send first prompt information.

2. The gas meter query method based on the compound IoT according to claim 1 , further comprising:
sending second 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 second prompt information, the second prompt information to a user sub-platform corresponding to the second gas meter.

3. The gas meter query method based on the compound IoT according to claim 1 , wherein the data information comprises identification information corresponding to the second gas meter, and the sending, by the management platform, the first control signal to the second gas meter via the sensor network platform comprises:
sending, by the management platform, the first control signal to the second gas meter corresponding to the identification information via the sensor network platform.

4. The gas meter query method based on the compound IoT according to claim 1 , wherein an indicator lamp is provided on the gas meter, and sending, by the management platform, the first control signal to the second gas meter via the sensor network platform to instruct the second gas meter to send the first prompt information comprises:
sending, by the management platform, the first control signal to the second gas meter via the sensor network platform, and illuminating, by the second gas meter, the indicator lamp according to the first control signal.

5. The gas meter query method based on the compound IoT according to claim 1 , wherein the method further comprises:
sending, by the management platform, when the gas balance of the second gas meter is less than a set threshold, a second control signal to the second gas meter via the sensor network platform to instruct the second gas meter to send third prompt information.

6. The gas meter query method based on the compound IoT according to claim 5 , 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.

7. The gas meter query method based on the compound IoT according to claim 6 , 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.

8. An IoT system comprising:
a management platform configured to:
receive, via a sensor network platform, data information of a gas card from a first gas meter of a plurality of gas meters, wherein the data information is sent by the first gas meter based on a determination that the data information of the gas card corresponds to a second gas meter of the plurality of gas meters, and
send a first control signal to the second gas meter via the sensor network platform to instruction the second gas meter to send first prompt information.

9. The IoT system according to claim 8 , 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.

10. The IoT system according to claim 8 , wherein the data information comprises identification information corresponding to the second gas meter, and sending, by the management platform, the first control signal to the second gas meter via the sensor network platform comprises:
sending, by the management platform, the first control signal to the second gas meter corresponding to the identification information via the sensor network platform.

11. The IoT system according to claim 9 , wherein an indicator lamp is provided on the gas meter, and the step of sending, by the management platform, the first control signal to the second gas meter via the sensor network platform to instruct the second gas meter to send the first prompt information comprises:
sending, by the management platform, the first control signal to the second gas meter via the sensor network platform, and illuminating, by the second gas meter, the indicator lamp according to the first control signal.

12. The IoT system according to claim 8 , wherein when the gas balance of the second gas meter is less than a set threshold, the management platform further sends a second control signal to the second gas meter via the sensor network platform to instruct the second gas meter to send third prompt information.

13. The IoT system according to claim 12 , wherein when the gas balance of the second gas meter is less than the set threshold, the management platform further sends fourth prompt information to at least one of a plurality of service sub-platforms;
one of the service sub-platforms that receives the fourth prompt information sends the fourth prompt information to a user sub-platform corresponding to the second gas meter.

14. The IoT system according to claim 13 , wherein when the gas balance of the second gas meter is less than the set threshold, the management platform estimates a remaining gas usage time limit of the second gas meter according to an average gas consumption rate of the second gas meter, and sends 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.
