In an alternative embodiment, after step S205, the method further includes:
based on the device information and the battery usage data, a second operating strategy and/or a third threshold is generated, the third threshold being transmitted to the gas flow meter terminal for instructing the gas flow meter terminal to transmit a condition of the second alarm information. Because the minimum voltage which is required to be reserved for maintaining the basic operation of the gas flowmeter terminals of different types is different, the necessary functions of the gas flowmeter terminals of different types are also different, and meanwhile, the battery usage data of the gas flowmeter terminals of different types are also different, so that a management platform is required to formulate different second operation strategies according to equipment information to ensure the basic operation of the gas flowmeter terminals, and meanwhile, the management platform can also formulate different third thresholds for different gas flowmeter terminals according to the equipment information and the battery usage data. The management platform generates the second operation strategy and/or the third threshold according to the equipment information and the battery usage data, so that the fact that most of gas flowmeter terminals can maintain the same or similar basic operation time after the second operation strategy is executed can be ensured, maintenance personnel are required to go to the gate for processing after the second operation strategy is executed by general gas flowmeter terminals.
In an alternative embodiment, the second operation strategy is used for indicating the operation strategy of the gas flowmeter under the off-line state; when the gas flowmeter terminal receives and executes the second operation strategy, the electric quantity of the built-in battery of the gas flowmeter terminal is left, in order to ensure that the basic functions of the gas flowmeter terminal can be executed, such as opening and closing a valve, and ensuring the safety of the gas flowmeter terminal, the gas flowmeter terminal may stop all unnecessary functions including communication with the management platform, the second operation strategy can be used for indicating the working strategy of the gas flowmeter terminal in an off-line state so as to ensure the basic safety of the gas flowmeter terminal, meanwhile, when the gas flowmeter terminal executes the second operation strategy, the gas flowmeter data acquired during the execution of the second operation strategy are temporarily stored in the local memory, and when the gas flowmeter terminal resumes communication with the local memory, the flow data in the local memory are uploaded to the management platform.
