With the development of social economy and science, the demand of people for gas resources in production and life is increased dramatically, and the gas resources face the dilemma of being exhausted increasingly, so that an intelligent gas management system is urgently needed to meet the social development.
At present, the IC card intelligent gas meter on the market has the advantages of mature technology, low cost, safety, durability, management function and the like. But has no communication function and prepayment function, so only the user can check meter and pay after using gas. Therefore, the problems of difficult meter reading, difficult charging, difficult management, disputes caused by human factors, cheating and the like exist. Meanwhile, the existing operation mode needs a huge management team, so that the operation mode is more in personnel, low in efficiency and high in cost. Therefore, the development requirements of modern economic life have not been met. However, the background management system cannot monitor the running state of the system due to the fact that the system has no communication function, and the meter reading efficiency is seriously affected by the problems of difficulty in household meter reading, high after-sales cost and the like.
For example, the IC card collection and payment method requires that the user must hold a card to a designated toll gate or bank to pay, which increases the time cost and operation cost, and the gas meter has inherent technical drawbacks and high after-sales cost. The IC card meter has no communication function, and the background management system cannot monitor the running state of the IC card meter, so that the IC card meter is not easy to discover and process in time once a fault occurs. The difficulty of checking meter at home causes that operators cannot timely and accurately know the gas conditions of residents. If a new price is implemented, the IC card meter cannot be updated on line, and the meter can be replaced to adapt to the price change. Most of the IC card meters adopt non-encryption type IC cards or logic encryption cards as user cards, are easy to decrypt and unsafe.
