Presence of traditional meter reading - manual meter high management costs , labor-intensive, low efficiency of many abuses , and has brought great inconvenience to the management center and the user . Wireless smart meter-reading system uses wireless transceiver module sends data to be copied into the interior of the case to read meter data and receive data with high accuracy , so it has the incomparable advantage of traditional meter reading , wireless communication - based smart The meter-reading system has attracted wide attention both at home and abroad . Slightly modified the design on the basis of traditional meter that the installation of a magnetic sensor in the mechanical meter , mechanical water meter rotation is converted to electrical pulse signal . Research and innovations are as follows : First acquisition pulse end , magnetic sensors installed on the user 's meter , magnetic sensors to the rotation of the water into the pulse output , pulse transmission via wireless transmission module to the handheld meter reading instrument ; Secondly receive data end , hand-held meter reading instrument received by the wireless receiver module pulse data stored in the storage module , and displayed by the liquid crystal display , set the keyboard to type your user name and the date , and received all the information and data through the USB interface and PC communication ; the last brief introduction to a key part of the system , the key research and the development of the wireless communication protocol of the system , handheld meter reader and PC communication host computer receives and stores display data core content , to debug the system to achieve the expected function . We build wireless smart meter-reading system capable of real-time and accurate copy reading user data , not only can copy to read meter data across the door , but also has the advantage of ultra - low power consumption to make up for the lack of traditional meter reading , analysis of the management center processing data providing convenient.
