Detailed Description
In order to solve the problems of high upgrading cost and difficult upgrading when broadband upgrading is carried out on equipment in a meter reading system, the embodiment of the application provides a meter reading method, a meter reading device and a meter reading system.
The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it should be understood that the preferred embodiments described herein are merely for illustrating and explaining the present application, and are not intended to limit the present application, and that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
At present, a narrow-band carrier concentrator and a narrow-band carrier electric energy meter in a meter reading system are communicated by using a narrow-band carrier signal, and the narrow-band carrier electric energy meter can not be upgraded in order to reduce the upgrading cost by considering that the transmission distance of the narrow-band carrier signal is longer, the narrow-band carrier concentrator also has the function of summarizing the electric quantity information of each narrow-band carrier electric energy meter within a certain time period, the data processing quantity and the data transmission quantity are large, therefore, it is necessary to upgrade the narrowband carrier concentrator to meet the real-time requirement of the primary station on the acquired power information, but at the moment, a broadband carrier concentrator supporting broadband carrier communication and a narrowband carrier electric energy meter supporting narrowband carrier communication are simultaneously generated in the meter reading system, due to the fact that the frequency bands of the broadband carrier wave and the narrowband carrier wave are different, communication cannot be conducted between the broadband carrier wave concentrator and the narrowband carrier wave electric energy meter.
In order to solve the problem, the inventor thinks that a dual-mode communication module is added between the broadband carrier signal and the narrowband carrier signal, and the dual-mode communication module is used for realizing the mutual conversion between the broadband carrier signal sent by a broadband carrier concentrator and the narrowband carrier signal sent by a narrowband carrier electric energy meter; when the narrow-band carrier electric energy meter needs to send a message to the wide-band carrier concentrator, the message can be carried in the narrow-band carrier signal and sent to the dual-mode communication module, the dual-mode communication module is responsible for converting the narrow-band carrier signal carrying the message into a wide-band carrier signal, and then the wide-band carrier signal carrying the message is sent to the wide-band carrier concentrator, so that the problem of communication between the narrow-band carrier electric energy meter and the wide-band carrier concentrator can be well solved.
In addition, the transmission distance of the narrowband carrier signal is relatively long, but the stability is relatively poor, so that in specific implementation, the situation that the electric quantity information of some narrowband carrier electric energy meters cannot be read may occur.

In particular, after the dual-mode communication module receives the first wideband carrier signal, the dual-mode communication module can modulate and demodulate the first wideband carrier signal to obtain a first narrowband carrier signal, and then the first narrow-band carrier signal is sent to each narrow-band carrier electric energy meter connected with the narrow-band carrier electric energy meter, each narrow-band carrier electric energy meter can read the electric quantity information of the narrow-band carrier electric energy meter according to the meter reading instruction carried in the first narrow-band carrier signal, the read electric quantity information can be carried in a second narrow-band carrier signal and sent to the dual-mode communication module, the dual-mode communication module can also modulate and demodulate the second narrow-band carrier signal sent by each narrow-band carrier electric energy meter to obtain a second broadband carrier signal, and then the second broadband carrier signal is sent to the broadband carrier concentrator, and after the broadband carrier concentrator receives the second broadband carrier signal, the broadband carrier concentrator can store the electric quantity information carried in the second broadband carrier signal.
When the broadband carrier electric energy meter receives the first broadband carrier signal, the electric quantity information of the broadband carrier electric energy meter can be read, the read electric quantity information is borne in the third narrowband carrier signal and is sent to the broadband carrier concentrator, and after the broadband carrier concentrator receives the third broadband carrier signal, the electric quantity information borne in the third broadband carrier signal can be stored.
In addition, in specific implementation, after the broadband carrier concentrator stores the electric quantity information carried in the broadband carrier signal, the broadband carrier concentrator can analyze and summarize the stored electric quantity information, and further, when a preset reporting condition is met, the analyzed and summarized data is carried in a fourth broadband carrier signal and reported to the master station.
