Embodiment Construction

[0030] The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, only used to explain the present invention, and should not be construed as a limitation of the present invention.

[0031] like figure 1 Shown is a flow chart of a preferred embodiment of the present invention. The method includes: inputting a table number on the CIU, and judging whether the CIU is in a bound state with a prepaid table; Whether the specified meter number is consistent, if not, bind the input meter number, and the user can query the prepaid meter by entering a short code; if the input meter number is consistent with the bound meter number , it means that the CIU matches the prepaid m...

Abstract

The invention relates to a method for authentication of rights between a prepaid meter and a CIU, and is characterized in that: the method includes: S1, inputting a meter number on the CIU, and judging whether the CIU is in a bound state with the prepaid meter; S2, if it is, then Continue to judge whether the input table number is consistent with the bound table number; if not, bind the input table number to query the meter information; S3, if the input table number is consistent with the bound table number, It means that the CIU matches the prepaid meter successfully, and the meter information is queried; if not, enter the unbinding code to unbind the bound meter number, and return to S1. This design can ensure that a CIU can only bind a unique table number at a time. If a new table number is to be bound, the original table number must be unbound. In the sense of "one-to-one" mode between CIU and prepaid meters, it improves the security of meter information.

Description

technical field [0001] The invention relates to the field of prepaid meters, in particular to a prepaid meter and a CIU authority authentication method. Background technique [0002] Prepaid meters are widely used in the measurement of water, electricity and other fields because of their small size and convenient use. The existing prepaid meter is usually provided with a CIU used in combination with the prepaid meter, that is, a user interface unit, for viewing the related data of the meter. The communication between the prepaid meter and the CIU can be wired, wireless, infrared or power carrier. [0003] At present, when the carrier mode is used for communication between the prepaid meter and the CIU, the meter numbers of the CIU and the meter can be bound multiple times, that is, the "one-to-many" mode. As long as the meter number is known, multiple meters can be operated, so that the information security of the meters cannot be sufficiently guaranteed. SUMMARY OF THE ...
