| It is used for automation of water supply dispatching and safety
protection of equipments of water plant. It mainly consists
of industrial controller (host), short-wave radio station, large-screen
display (or mimic board), printer, power supply, antenna, UPS
and terminal equipments as required in the spot. |

Functions
and Characteristics |
|
 |
Remote control, detecting, signaling
and adjustment of all the terminal equipments; |
|
Set the running current, voltage, pressure,
alarm of water level limit, terminal address code and time in
the spot; |
|
Patrol the water level, pipe pressure
and flux, equipments' voltage, current, rotate speed and temperature
periodically and store the data and print the table regularly
or momentarily as required; |
|
Functions of automatic alarm display
of parameter over operation limitation, abnormal power supply,
guard against theft and acoustic/voice alarm. When power feed
circuit interrupted, the terminal can switch to DC storage battery;
and when the power supply loses phase or three-phase currents
are extremely imbalanced, the terminal can turn off the equipments'
power immediately; |
|
Large-screen display system simulation
chart, sketch map and statistical data curve according to the
field situation at the time of normal remote control and detecting;
or the mimic screen display all power supply circuits, water
pipes, terminals and distribution of the system and operation
status and parameters of the controlled equipments with relief
map of the system overlay zones as background; |
|
Automatic check and statistics of available
machine time, working time and other working parameters of all
the terminal executing equipments, and create various statistics
curves of production data of daily sheets, monthly tables and
annual statements automatically and display at any moment; |
|
Functions of extending and networking
; |
|
Able to monitor, call or talk with any terminal
at any moment. |
