In order to solve the problems that existing wireless meter reading systems and methods cannot realize a group reading mode of "area reading for each reading" and have low meter reading efficiency, the invention puts forward a wireless meter reading system and a broadcast-type reading mode. The wireless meter reading system includes a meter terminal and a meter reading instrument. The meter reading instrument is internally provided with a form download module, a broadcast instruction module, a data receiving module and a data storage module. The meter terminal is internally equipped with a meter reading acquisition module and a wireless transceiving module. Communication can be established between the broadcast call instruction sent by the meter reading instrument and a plurality of meter terminals within a period of time, and data can be transmitted, so that the group reading mode of "area reading for each reading" can be realized finally, the work efficiency is effectively improved, and the labor force and time of the operation personnel are saved.
Description
technical field [0001] The invention relates to the technical field of remote meter reading, in particular to a wireless meter reading system and a broadcast reading method. Background technique [0002] At present, smart natural gas meters for households are usually powered by batteries. In order to save electricity, the wireless transceiver module installed inside the meter usually adopts the energy-saving mode of "sleep and wake up" to work. The so-called "sleep wake-up" mode means that the wireless transceiver module of the meter is in a sleep state for a large proportion of the time, and only wakes up in a very short period of time to check whether there is an external call signal. If there is a call signal when it wakes up, it communicates with it. Otherwise, it will go back to the sleep state again, and the cycle will work like this. The transceiver device used for meter reading is usually a meter reading device, in which a data storage module and a central signal tr...
