Heart controller 240 is judged by core controller 240.Specifically, detection module 150 by in charge-discharge modules 140
Electronic device connection, the charged state and the state of activation of the voltage swing of real-time detection backup power supply 210, backup power supply 210,
Judge whether backup power supply 210 under-voltage by core controller 240, whether can charge normal and discharge, charging current whether just
Often etc..It should be noted that distribution terminal power state information can also include the shape of exchange input two-way switching module 170
Whether state, specially double-circuit communication electricity can normally provide the information such as alternating current and the current route for providing alternating current, above
It has been already mentioned that details are not described herein.
Control instruction is mainly after core controller 240 judges the power state information that detection module 150 is fed back,
The control instruction sent to control module 120 makes it control the execution modules such as charge-discharge modules 140 and executes corresponding operation.Show
Example property, when inputting without exchange or needing to activate backup power supply 210, backup power supply power supply enabled instruction is sent, by
Backup power supply 210 is powered；After alternating current restores normal or activation, backup power supply power supply open command is sent.It can
To preset its activity cycle according to the parameter of backup power supply 210, according to the activity cycle, backup power supply activation is periodically sent
Enabled instruction after activation, sends backup power supply and activates open command.The float charge voltage of different backup power supplies is different, because
This needs to send the instruction of backup power supply float voltage setting, controls AC-DC conversion module 130 by control module 120 and exports
Corresponding float charge voltage.In underfill electricity, charging to backup power supply 210 generally therefore can be to control using constant current mode
Module 120 sends the setting instruction of backup power supply charging current, carries out control module 120 to the circuit in charge-discharge modules 140
Corresponding control, to obtain corresponding charging current.Instruction is read by sending distribution terminal power state information, makes to control mould
Block 120 controls detection module 150 and carries out detecting operation accordingly.
Distribution terminal electric source modes are corresponding with control instruction, therefore, in addition to aforementioned power source mode, distribution terminal power supply
Mode further include: the float charge voltage of backup power supply 210 is arranged by AC-DC conversion module 130 for control module 120；Control
