Optionally, timesharing power supervisor includes at least two controls to connect one to one at least two load equipments
Switch.Control host can control at least two control and switch on-off, to control the break-make of the outlet line of UPS, in turn
The break-make for the load equipment that control connects one to one at least two control switch.Optionally, which can divide
At least two control switch is not controlled, or controls at least two control switch simultaneously.
Certainly, timesharing power supervisor can also include the control switch being connected between UPS and power control module, control
Host processed can control the control and switch on-off, to control the break-make of the outlet line of UPS.
Exemplary, as shown in Figure 2 D, timesharing power supervisor 12 further includes one-to-one at least two load equipments
Control switch w1, w2 to wn (n corresponds to the number of load equipment 13, and n is the integer more than 1), control switch w1 is arranged in work(
Between the control terminal y1 load equipments corresponding with control terminal y1 of rate control module 122；Control switch w2 is arranged in power control
Between the control terminal y2 load equipments corresponding with control terminal y2 of molding block 122；... control switch wn is arranged in power control mould
Between the control terminal yn load equipments corresponding with control terminal yn of block 122.It controls host 15 and switch w1, w2 is controlled extremely by control
The break-make of wn controls the break-make of corresponding control terminal and the circuit of corresponding load equipment.
Optionally, above-mentioned control switch can be dry contact, and dry contact is a kind of passive electric switch, have disconnect and
Two states are connected.Exemplary, control host can be by sending dry contact signal (also referred to as switching value to timesharing power supervisor
Signal) come realize above-mentioned two situations circuit control.Dry contact signal includes that dry contact Continuity signal and dry contact disconnect letter
Number, for example, 0 represents dry contact Continuity signal, 1 represents dry contact cut-off signal.It controls between host and timesharing power supervisor
At least a pair of of dry contact circuit, at least a pair of of at least one of dry contact circuit and timesharing power supervisor stem grafting can be set
Point corresponds, and each pair of dry contact circuit is used to control the break-make of corresponding dry contact.Each pair of dry contact circuit includes input line
Road and outlet line, the incoming line are used to send dry contact signal, the output line to timesharing power supervisor for control host
Road is used to return to dry contact signal to control host for timesharing power supervisor.
It is exemplary, it is assumed that timesharing power supervisor includes the total n+1 control of control switch s1, control switch w1, w2 to wn
Switch, and this n+1 control switch is dry contact, then in order to effectively realize the control of dry contact, controls host and timesharing electricity
N+1 can be set between source manager to dry contact circuit.To control the worked of corresponding a pair of of the dry contact circuits of switch w1
For journey, if control host needs to control control switch w1 unlatchings, the control host is by corresponding incoming line to timesharing
Power supervisor inputs dry contact Continuity signal 0；For timesharing power supervisor after receiving the dry contact Continuity signal, control should
It controls switch w1 to open, dry contact Continuity signal 0 is then exported to control host by outlet line, to be carried out to control host
Response, to inform that control host completes the unlatching of control switch w1, above-mentioned control control switch w1 is opened and is rung
The action answered can be completed by the controller in timesharing power supervisor.Other control the course of work of switch similarly, this practicality
It is novel that this is repeated no more.
It should be noted that input line of the timesharing power supervisor in addition to UPS can be controlled by above-mentioned two situations
Road, and/or, except the break-make of outlet line, when timesharing power supervisor include above-mentioned switch module, access breaker and/or
When main breaker etc. has the structure of switching function, which can also control this with switching function by controller
The break-make of structure controls the incoming line of UPS, and/or, the break-make of outlet line.Exemplary, which still can be with
Controller is controlled by dry contact signal, to control the corresponding structure with switching function by controller.
In practical application, which can be the control host with specified function, such as the control host can be with
