Claim Text:
1. An internet of things (IoT) intelligent gas meter system, comprising: a gas source outlet and a gas source inlet installed on a base meter, an electromechanical valve installed near the gas source inlet, a Central Processing Unit (CPU) control module to send a control signal to the base meter, wherein the CPU control module includes an EEPROM data storage device and is connected to the base meter; and a gas consumption criterion of the base meter is adjusted in real-time in response to the control signal from the CPU control module, wherein the criterion is determinable by gas prices; wherein the adjustment to the gas consumption criterion of the base meter is determined by: a data transmission module to receive the control signal from a remote computer management system and feedback gas consumption information relevant to a gas meter sent from the CPU control module to the remote computer management system, wherein the data transmission module is indirectly connected to the internet and connected to the remote computer management system via the internet; the data transmission module, which includes a signal transmitter and signal receiver, to exchange data with the CPU control module via a data command busbar, wherein the signal transmitter is connected to a data concentrator in a wired or wireless manner, wherein the data concentrator is connected to the Internet via a network communication protocol and sends the gas consumption data from the gas meter to the remote computer management system in the form of data packets; and the CPU control module adjusts and encrypts the data in the EEPROM data storage device and sends the encrypted data to the Internet via the signal transmitter according to the network communication protocol in the form of data packets, wherein the encrypted data includes an abnormal condition which includes an overflow rate or magnetic disturbances, and the data packets are forwarded to the remote computer management system across the Internet, and wherein the remote management system is further connected to a plurality of IoT intelligent gas meters, wherein each IoT intelligent gas meter is a node in a control system, wherein the nodes are connected to the data concentrator and transmit data to the data concentrator, wherein the data concentrator, after data is collected from each node, is connected to the Internet via an interface and transmits the data to the remote computer management system, and wherein the remote computer management system is integrated with a charge management system and a working state management system for gas meters, wherein the charge management system comprises: a basic data module to manage site settings, regional settings, meter type settings, payment type settings, manufacturer settings, administrator settings and invoice format settings; a gas sales business management module to open an account, pay fees, refund and supplement gas for a gas consumer; a financial statements management module to prepare a basic information report of the gas consumer, payment information reports of the gas consumer, the meter reading information report of the gas consumer, daily report, monthly report and annual reports; wherein the working state management system of gas meter comprises: a regional management module to set a management site, management community, management unit and a management building; a user management module to cancel the account, transfer and modify basic information of the gas consumer; a usage state management module to inquiry a historical status and an instantaneous state, wherein the historical status inquiry includes a historical query of a remote switch valve, a historical query of remote meter reading, historical query of online payment and historical query of gas price adjustment, wherein the instantaneous state inquiry includes a low gas alarm query, a high-low pressure protection query, a super flow protection query, a time-out protection query, a strong magnetic protection query, a remaining amount of gas query, a cumulative gas consumption, a cumulative recharge amount query and an instant gas price query; a maintenance management module to eliminate HP and LP failures, superfluid failure, timeout failure and magnetic interference failure; a meter replacement management module to inquiry the information of a recorded faulted meter, record information of a new meter and transfer data.
