Problems solved by technology

In terms of characteristics, the 485 bus needs to lay a large number of cables, and the construction is extremely cumbersome. The power carrier technology is not yet fully mature, especially during the peak period of power consumption, which often leads to a low communication success rate and is difficult to meet the requirements.
ZigBee wireless module, using 2.4GHz frequency for wireless communication, has poor penetration, short transmission distance, and cannot adapt to the complex environment on site

Description

technical field [0001] The invention relates to a data acquisition device, in particular to an electric meter data acquisition device. Background technique [0002] At present, the operation of residential electricity in my country still mainly relies on traditional manual meter reading, which not only has cumbersome procedures and heavy statistical workload, but also cannot guarantee the accuracy and integrity of data, resulting in low efficiency of power operation. [0003] At present, domestic experts have proposed a series of meter reading schemes, such as: 485 bus, power line carrier, ZigBee wireless and other communication methods for meter data collection. In terms of characteristics, the 485 bus needs to lay a large number of cables, and the construction is extremely cumbersome. The power carrier technology is not yet fully mature, especially during the peak period of power consumption, which often leads to a low communication success rate and is difficult to meet th...
