Data Acquisition with microcontroller as the core data
collection devices, with 10 test pulse meter data collection.
To protect the system security and reliability, the data
collector should have the system data and collecting data
storage capabilities, while cut-line with user, the system
bus disconnection, power failure alarm function. Data
acquisition devices as having communication capabilities,
with focus on the communication between devices using
mature technology of the RS-485 bus mode. Collector
mainly by the CPU, the valve control circuit, the pulse
signal acquisition circuit, RS-485 communication
interface circuits, data, data storage and tamper circuits so
on. Acquisition of the pulse signal processing, storage and
through RS-485 bus to communicate with the
concentrator, when after receiving the upper command by
controlling the electric valve to control the user of water
