In order to facilitate the understanding of the technical contents of the present invention by those skilled in the art, the present invention will be further explained with reference to the accompanying drawings.
The collector and the concentrator can be mutually converted, and when the SIM card is installed, the collector is the concentrator, otherwise, the collector is the collector; all data of the collector are transmitted to a data center through a concentrator; when the data center calls the collector, the data center transmits the data through the corresponding concentrator, and the concentrator and the collector communicate on the RF default frequency band; the data transmission process of the concentrator and the collector comprises the following steps: the concentrator receives the command of the data center, transmits the corresponding collector through the default frequency band, the collector transmits the command back to the concentrator after processing, and the concentrator transmits the command to the data center.
As shown in fig. 1, the data forwarding process from the concentrator to the collector includes:
a1, the concentrator receives an operation command sent by the data center through the GPRS network, and executes the step A2; the concentrator detects whether an operation command issued by the data center is received through the GPRS network or not at intervals of a time interval T, and the time interval T is set according to actual needs.
A2, judging whether the command is the operation of the concentrator or the collector, and if the command is the operation of the concentrator, carrying out corresponding operation on the concentrator; otherwise, turning to the step A3 to operate the collector; after receiving an operation command issued by a data center, the concentrator judges whether the command is directed to the concentrator or the collector; if the operation command of the concentrator is directed, performing corresponding operation processing on the concentrator without issuing; and if the command is an operation command for the collector, the command is sent to the designated collector through RF communication.
A3, judging whether the collector is legal, if not, reporting abnormal information through a GPRS network; otherwise go to step A4; in practical application, for the purposes of product management and usability and reliability of a gas meter company, the concentrator and the acquisition can be exchanged, and the difference is whether an SIM card is inserted or not; therefore, whether the collector exceeds the SIM card or not needs to be judged, if so, the collector is illegal, and the concentrator reports abnormal information to the data center through the GPRS network.

a10, the concentrator decomposes GPRS data and loads RF data; when the RF small wireless is in an idle state and the collector does not reach the maximum operation times, the concentrator decomposes the GPRS data, loads the RF data and sends the RF data to the collector through RF communication.
A11, the concentrator sends RF data to the collector;
a12, the concentrator is protected in the maximum time length to wait for returning, and whether the concentrator correctly receives the return result is judged; if yes, ending; otherwise go to step A13;
a13, judging whether the maximum operation times of the collector are reached; if so, reporting abnormal information through a GPRS network; otherwise go to step A11; if the return result is not correctly received, the collector is checked again whether the maximum operation times is reached, and if not, the concentrator sends the RF data again.
