Stand-by state；
After one in direct current or the retired power battery of Alternating Current Power Supply enters alarm condition, using alternating current-direct current reserve battery
Group C investment replaces powered operation mode.If direct current supply battery pack A or the same alarm of Alternating Current Power Supply battery pack B, directly switch
To diesel-driven generator powering mode.
Fig. 3 is alarm flow figure of powering after alternating current-direct current battery backup C is enabled.It is specified in figure when communication base station application is handed over
Three-level warning process when direct current battery backup C is led to after alternating current-direct current battery backup C operating status enters three-level threshold value
Crossing monitoring device makes alarm system enter alert status；After alternating current-direct current battery backup C operating status enters secondary threshold, lead to
Crossing monitoring device makes alarm system enter alarm status；After alternating current-direct current battery backup C operating status enters level-one threshold value, lead to
Crossing monitoring device makes alarm system enter alarm condition；In the present embodiment, battery management system BMS is to alternating current-direct current reserve battery
The threshold value division methods of group C are as follows:
The three-level threshold value H3 of alternating current-direct current battery backup C refers to that SOC is reduced to 0.3 or through the 4th DC/DC converter, the 4th
Voltage Drop refers to that SOC is reduced to 0.2 or through the 4th DC/DC converter, to 650V, secondary threshold H2 after DC/AC converter
After four DC/AC converters Voltage Drop to 640V, level-one threshold value H1 refer to SOC be reduced to 0.1 or through the 4th DC/DC converter,
Voltage Drop is to 630V after 4th DC/AC converter.
When enabling alternating current-direct current battery backup C, alternating current-direct current battery backup C is communication base by the 3rd DC/DC converter
The DC load power supply stood, alternating current-direct current battery backup C are communication by the 4th DC/DC converter and the 4th DC/AC converter
The power supply of base station AC load.Alternating current-direct current battery backup C selects the method for operation by single-pole three-throw switch, both can be negative for exchange
Load is powered and can be powered for DC load.If direct current supply battery pack A enters simultaneously with Alternating Current Power Supply battery pack B
Alarm condition then directly enables diesel-driven generator and is powered.Power supply is participated in when communication base station is in alternating current-direct current battery backup C
Under conditions of, as long as have direct current supply battery pack A and Alternating Current Power Supply battery pack B either party trigger alarm as long as system it is direct
Retired battery power supply system is cut off, system is directly entered diesel-driven generator power supply state.
Staff can carry out control by the prepared state to battery of three-level threshold operative mode, avoid battery
State suddenly change makes staff be caught unprepared.After system enters alert status, staff checks battery status, determines
Early warning accuracy；When system enters alarm status, staff checks status of backup battery, prepares investment reserve battery and supplies
Electricity；When system enters alarm condition, backup power source is put at once and replaces current supplying cell.When reserve battery is in power supply shape
After state, diesel-driven generator power supply is directly enabled if system is again introduced into alarm condition.
Communication apparatus establishes communicating terminal with the public network GPRS data service of base station, by base by way of wireless data
Data transmission of standing is to network server terminal.Staff can be by network access server terminal, to grasp each in base station
The state of equipment.Firewall is set up simultaneously, guarantees the safe and stable operation of communication apparatus.
