Automatic meter reading method and device

摘要: The invention provides an automatic meter reading method and device, belongs to the field of instruments. comprises steps that S101, acquiring identification information all to-be-read meters, wherein coordinate values; S102, a current value device; S103, respectively calculating difference between device each obtain set; S104, judging whether in set is smaller than preset threshold or not, if so, executing S105; S105, sending instruction target corresponding value; S106, receiving numerical sent by table; S107, updating number meters be read; S108, updated greater zero repeating S102 S108; S109; S109, ending operation. According function can realized, efficiency improved.
