Embedded WEB server
With the
H5920 DAM built-in Web server, it is easy for operators to
configure and manage the system operation by the IE browser.
NTP clock synchronizing
H5920 DAM supports NTP, it will synchronize the system clock
to a clock server over the Internet.
Remote configuration and editing
As we know, re-assigning of operation personnel, a change of
mobile phone number is also common. H5920 DAM allows users
to remotely add, change or
delete any mobile phone numbers in H5920 DAM memory.
Therefore, the authorized personnel can perform the change
from anywhere using their mobile phone. Where there are many
installed sites, this feature saves time and cost.
H5920 DAM also
has a feature to allow users to remotely define the SMS
contents including the site name, message description,
over-limitation, receipt and so on. The remote indications
can be defined in accordance with the events property by the
operator. There are four grades can be defined:
- Fatal: indicates the equipment or system does not
work.
- Serious: indicates the equipment or system
performance will be decreased.
- Warning: indicates the equipment or system is
something wrong.
- Notice: indicates the equipment or system operation
status has been changed.
Meanwhile, it is also very easy to change the settings
via web interface. Log into
H5920 DAM and the changes can be done remotely
over the Internet (if it is connected to Internet).
Remote querying
Authorized users can also send the specified SMS to query
the status of remote indication/measurement inputs or remote
control outputs. This is very useful feature to determine
the present status of monitored equipments.
SMS receipt and acknowledgement
If the receipt function enabled, when an alarm is triggered,
it will request a receipt from the SMS receiver to confirm
if the SMS has been sent, and then log this receipt at the
center server (if it is available).
If an alarm happened repeatedly at a specified interval
(can be set by user), the SMS will be
sent repeatedly to the users. To cancel repeat sending, any mobile phone
that received the SMS can acknowledge to H5920 DAM by
replying the acknowledge command. Once H5920 DAM received
the acknowledgement command is will stop sending further SMS
for this trigger. Event Logging
The H5920 DAM and monitored equipment operation events will
be logged. Every input-output triggering and SMS receipt that takes place
is captured and saved in flash memory. The received SMS are
also captured saved. Histories can be viewed on Web pages or
can be
saved to other database program for analysis and
reporting. Configuration and operation data backup
All the system configuration parameters and monitored
equipment operation status data can be retrieved to other
computers for backup.
RS-232/485 serial interface
At many circumstances, there is an equipment (i.e. power
meter, RTU, etc.) with RS-232 or 485 data interface. H5920
DAM provides two serial port interfaces for this connection.
For the specified device, Hongdian can provide the protocol
conversion software, and then send the related messages to
mobile phone user.
