The invention discloses a wireless remote-transmitting gas meter with an electric quantity alarm function. By virtue of a voltage detection module and buzzer combination method, early warning of a low battery is performed; a user is reminded of replacing the battery in time through a sound manner, so that the problem of flue gas cut-off due to power outage is avoided. Furthermore, according to the invention, early warning of the low battery is performed by virtue of color change of a liquid crystal display screen, for instance, when the battery voltage is less than or equal to a preset threshold, the liquid crystal display screen displays yellow background color under control of a microprocessor so as to remind of the lower battery, so that the user is reminded of replacing the battery in time from the aspect of visual effect; the SI4432-type wireless transmission module is adopted , so that the maximum distance can be up to 1800m, and the data transmission demand of the wireless remote-transmitting gas meter is met. According to the application, unique binding is performed on a user IC card and the wireless transmission module, so that when abnormal data of the wireless transmission module is received, the position of an abnormal gas meter can be rapidly positioned.
Description
technical field [0001] The invention relates to the field of intelligent gas meters, in particular to the technology of wireless remote transmission gas meters. Background technique [0002] At present, domestic smart gas meters mainly include IC card smart gas meters, CPU card smart gas meters, radio frequency card smart gas meters, direct-reading remote gas meters (wired remote meters) and wireless remote gas meters (integrated), etc. These categories, and with the improvement of people's living standards and quality of life, the demand for intelligent products required by modern families will promote the development of smart gas meters in the direction of safety, reliability, and smart convenience. [0003] Ordinary household membrane gas meters, due to the difficulty of charging, the high labor costs of meter readers, and the inability to monitor gas theft, have continuously increased operating costs for gas companies and brought many troubles to operation and management...
