1.5 Monitoring Functions of the Power System
1.5.1 Function Introduction
The monitoring module of the power system is used to monitor operation status and
environmental parameters of rectifier modules and distribution module. When the
monitoring module detects the abnormity, it can not only send light through the
panel, but also control the output of alarm dry contact according to the alarm class
of the current alarm information: JK1 will close when there is a serious alarm, and
JK2 will close when there is a general alarm.
The monitoring module of the power system also has the communication report
function. It can communicate with the host through RS232 or RS422 mode
according to the protocol defined internally by the enterprise. It can receive queries,
settings, and control from the host and can report the detected status and physical
parameters to the host for the convenience of centralized management.
The monitoring module of the power system also has the perfect battery
management function.
1.5.2 Expanding of System Monitoring Performance
1. Communication Function between Monitoring Module and the Host
The power system provides two communication ports for communication with the
host. The ports locate on the panel of the system monitoring module.
Users can write the host monitoring software oneself according to the
communication protocol provided by the enterprise and realize the remote message,
remote sense, and remote control by the monitoring module. Users can realize the
centralized monitoring and automatic management of the power system in
monitoring center via RS232 or RS422 communication lines.
Main communication functions that can be carried out between the power system
and the host:
(1) Sending real time analog data from the monitoring module to the host.
(2) Sending real time digital data from the monitoring module to the host.
(3) Sending alarm and status information to the host.
(4) Receiving control commands from the host such as on/off of rectifier modules.
(5) Receiving system configuration parameters set by the host and giving feedback
of the system configuration parameters to the host.
