A smart meter control system and method based on credit consumption

Abstract

The invention provides a credit consumption based intelligent instrument control system and a credit consumption based intelligent instrument method. The system comprises a user terminal, a background server and an intelligent instrument, wherein the user terminal is used for sending a credit consumption request to the background sever under the triggering of a user; the background server is used for judging if opening the intelligent instrument corresponding to a label according to the credit line corresponding to the account information; if so, the intelligent instrument is started; the intelligent instrument is used for starting a control valve under the control of the background server and monitoring if each function button or function option is triggered by the user; if so, the current flow and billing can be controlled according to the monitoring result; when the monitoring result is to close the use function, the control valve is closed and a consumption record of the user is generated and is sent to the background server; the credit line of the user is updated by the background server according to the consumption record. According to the embodiment of the invention, the framework of the intelligent instrument control system can realize card-free consumption, so that the user does not need to carry about the IC card and the fee for making card is saved.

Description

technical field [0001] The invention relates to the technical field of billing equipment, in particular to a credit consumption-based smart meter control system and method. Background technique [0002] At present, as the single-chip microcomputer technology becomes more and more mature, smart meters are also developed. For school students and enterprise employees to take a bath, schools or enterprises prevent users from washing with hot water and leaving them unattended after leaving. Faucets, and to prevent insufficient hot water supply caused by excessive water consumption in a single bath, schools or enterprises have installed billing smart meters in bathrooms and room showers, that is, water meters or water controllers, which charge according to the amount of water used by users, and then control users The phenomenon of wasting water resources; therefore, the application of billing equipment for bathing water such as bathhouses and apartment bathrooms, that is, water me...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the related art: In the related art, the smart water meter that measures the water consumption based on the smart IC card technology and performs consumption data transmission and settlement transactions requires the user to carry the IC card with him. , the control method is single, and once the IC card is lost, it will bring a certain loss to the user. In addition, not only the production of the card requires a certain cost, but also the production of a large number of IC cards is not conducive to environmental protection
