Method for buying fuel gas and recharging prepayment diaphragm gas meter

Abstract

The invention provides a method for buying fuel gas and recharging a prepayment diaphragm gas meter. The method is characterized in that all information can be sent out by means of short messages of a cell phone, and the users complete the gas-buying deal by the short message; after the deal is done, a cell phone or a SIM card is put close to the diaphragm gas meter to complete recharging of the meter; meanwhile, besides the existing gas-buying method, users can also go directly to a business hall to buy the fuel gas. Compared with the prior art, the method of the invention features simple process of registration and gas-buying, low use cost of the users and low cost of terminals, good safety and reduction of safety accidents caused by gas leakage; moreover, the users can also check gas-buying information, help information, fuel-gas using knowledge and the like by sending short messages; fuel-gas companies can send prompting messages to users by means of the short messages.

Description

technical field [0001] The invention relates to the field of gas meters, in particular to a method for prepaying gas fees by using communication equipment. Background technique [0002] In the prior art, contact IC cards and radio frequency cards are used to recharge gas meter prepaid appliances. Users need to go to the relevant business hall to pay the fee and transfer the amount to the card, and then the user goes to the meter and touches the card or approaches the gas meter. Finish recharging the prepaid gas meter. This technology exists: when recharging the prepaid gas meter, the user needs to go to the relevant business outlets to contact the IC card and the radio frequency card, which cannot solve the problem of timely and fast payment of the prepaid gas meter, and at the same time causes waste of manpower and time for the user. the inconvenience of life, such as figure 1 , figure 2 ; And, the setting of a large number of business points increases the operating cos...

Problems solved by technology

This technology has the following problems: 1. The payment terminal directly uses the mobile public network to communicate, and the communication requires a lot of energy. A rechargeable battery is required as a power supply, and the battery needs to be charged frequently, which brings troubles to gas users during the use of gas. At present, , prepaid gas meters basically use disposable batteries. If you use disposable batteries in payment terminals based on wireless mobile public networks, the battery life cycle is very short and needs to be replaced frequently, which increases the cost of users. Therefore, this method does not It is suitable for use on terminals powered by disposable batteries; 2. The payment terminal directly uses the mobile public network to communicate, and it is necessary to add a circuit related to the communication with the mobile public network in the table, and the construction of a dedicated circuit will greatly increase the cost of the terminal; 3. Payment The terminal directly uses the mobile public network to communicate, and it is necessary to place a mobile phone card or a card with a function equivalent to a mobile phone card into the terminal, which increases the cost of the terminal; 4. The card configured for each terminal to communicate with the public network needs to use public network resources , requires resource usage fees; 5. The payment terminal must be equipped with a dedicated input device, such as a keyboard, in order to realize the transaction operation, which increases the cost of the terminal and increases the size of the terminal, which brings trouble to the installation; 6. The terminal uses the public network for communication, and the communication station releases The energy is very high. If this method is applied to a gas meter, when there is an accident such as gas leakage, the high energy released by the communication may cause a gas fire or gas explosion accident, so this technology is not suitable for use in places where gas is easy to leak, such as natural gas Mobile phones banned in gas stations
