Problems solved by technology

[0013] The purpose of the present invention is to provide a smart card meter payment method, which is used to realize the post-payment of water supply, electricity, natural gas, gas, etc., solves the problem of manual meter reading, and facilitates the realization of ladder water prices, peak and valley electricity prices, and card-based payment. The remote transmission method prevents users from collecting water, collects water information in time, solves the problem of information lag, and has less management personnel and management costs. It solves the problem of difficult construction of wired remote transmission and transmission blind spots in wireless remote transmission, and does not affect the water department. business management decision-making model

specific Embodiment approach

[0062] The user card water meter application parameter file stores various parameters necessary for water meter operation and water company management. The reason why these parameters are stored in the user card is that the user card is used as the transmission medium to write the management information of the water company. In the water meter, this file must exist in the user card. User card application parameters include public parameters, post-payment method parameters, and pre-payment method parameters, as shown in Table 1:

[0063] Table 1: User card application parameter table

[0064]

[0065] Explanation of each field:

[0066] Card type: used to indicate the type of card to distinguish whether it is a user card or a management card;

[0067] User number: user number, consistent with the table number, one table corresponds to one card;

[0068] Sub-meter occupancy sign: used to distinguish multiple identical water meters in the user's home;

Abstract

The method includes following steps: setting up time on meter for closing valve; recording measurement value at the specific time, and resetting measurement value of the meter; setting up the meter through application parameter of user's card, and reading out feeing time from user's card and corresponding time of closing valve inside meter, and comparing them; if feeing time is earlier than the time of closing valve, then writing information of meter to the user's card, and turning valve open; otherwise, updating state of the meter, entering into next measuring cycle, and turning valve open; if there is no feeing recorder in the meter at end time of measuring cycle, then closing valve, and checking whether there is a corresponding feeing recorder on the user's card; if no, then writing related values properly, and waiting user to insert card to turn valve open after paying the fee. The invention is applicable to multifold meters, and possible to implement stepped water rate.

Description

technical field [0001] The invention relates to the field of smart card meters, in particular to a smart card meter payment method, specifically a method and a system capable of realizing a prepayment method, a postpayment method and their combination. Background technique [0002] With the increasing scarcity of natural resources, especially the scarcity of water resources, this problem is particularly prominent in some large and medium-sized cities. How to effectively avoid the waste of water resources, rationally allocate and use the water resources we depend on for survival We have a very serious problem before us. The tiered water price is to implement a low price for the water within the quota on the basis of reasonably checking the basic consumption of residential water and various types of business water, and implement a progressive increase in excess of the basic water consumption. Compared with the relatively fixed water price in the past, the stepped water price ...
