At present, complete supply equipment used in the market mainly uses single system control mode, when control system occurs
Problem, complete equipment just can not normal operations.
Utility model content
The utility model is directed to problem and shortage existing for prior art, there is provided a kind of new secondary water-supply double control
System.
The utility model is that solve above-mentioned technical problem by following technical proposals：
The utility model provides a kind of secondary water-supply dual control system, and its feature is, it includes a frequency converter, a use
In gathering the signal picker of frequency variation signal of the frequency converter, multiple auxiliary reclays, one-to-one with the auxiliary reclay
Water pump, an alarm, one are used to receive the frequency variation signal and the break-make of those auxiliary reclays are controlled according to the frequency variation signal
Master controller, one are used to receive the frequency variation signal and the standby control of the break-make of those auxiliary reclays are controlled according to the frequency variation signal
Device processed and one is used to send an enabling signal when detecting that the master controller breaks down to the spare controller and sends one
Alarm signal to the alarm switch controller；
The frequency converter electrically connects with the signal picker, the master controller and the signal picker and those auxiliary reclays
Electrical connection, the spare controller electrically connects with the signal picker and those auxiliary reclays, the switch controller respectively with this
Master controller, the spare controller and alarm electrical connection, each auxiliary reclay electrically connect with corresponding water pump.
It is preferred that the spare controller is PLC (programmable logic controller (PLC)).
It is preferred that the secondary water-supply dual control system also includes a switch board, the master controller and the spare controller
It may be contained within the switch board.
On the basis of common sense in the field is met, above-mentioned each optimum condition, can be combined, produce the utility model respectively compared with
Good example.
Positive effect of the present utility model is：
The utility model is that switch board is provided with two control system units (i.e. master controller and spare controller), one
When individual control system unit goes wrong, Beck-up Control System unit is automatically switched to, can be good at solving traditional single control
The control system that system processed easily occurs once goes wrong, whole equipment just can not automatic running the drawbacks of.
Brief description of the drawings
Fig. 1 is the structural representation of the secondary water-supply dual control system of the utility model preferred embodiment.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer

The embodiment stated is the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made, all belongs to
In the scope of the utility model protection.
As shown in figure 1, the present embodiment provides a kind of secondary water-supply dual control system, it includes a frequency converter, one is used for
Gather the signal picker 4 of the frequency variation signal of the frequency converter, multiple auxiliary reclays 5, one-to-one with the auxiliary reclay 5
Water pump, an alarm, a switch board, one are used to receive the frequency variation signal and control those auxiliary reclays according to the frequency variation signal
The master controller 1, one of 5 break-make is used to receive the frequency variation signal and control those auxiliary reclays 5 according to the frequency variation signal
The spare controller 3 and one of break-make is standby to this for sending an enabling signal when detecting that the master controller 1 breaks down
Controller 3 simultaneously sends an alarm signal to the switch controller 2 of the alarm, wherein, the spare controller 3 is PLC.
The frequency converter electrically connects with the signal picker 4, the master controller 1 and the signal picker 4 and those among after
Electrical equipment 5 electrically connects, and the spare controller 3 electrically connects with the signal picker 4 and those auxiliary reclays 5, the switch controller 2
Electrically connected respectively with the master controller 1, the spare controller 3 and the alarm, each auxiliary reclay 5 with corresponding water pump
Electrical connection, the master controller 1 and the spare controller 3 may be contained within the switch board.
Secondary water-supply dual control system of the present utility model, master controller 1 gather frequency converter by signal picker 4
Frequency variation signal, the break-make of each auxiliary reclay 5 is adjusted according to frequency variation signal, and then increase water pump or reduce the work of water pump
Quantity.Once master controller 1 breaks down, switch controller 2 detects that master controller 1 breaks down, now, switch controller
2 automatically switch to back-up system mode of operation, that is, start spare controller 3, be simultaneously emitted by master controller fault signal, inform pump
Room administrative staff's maintenance process.
The utility model is organically combined using main system, back-up system, solves broken down in control system well
When many disadvantages that can not run of equipment, ensure the real-time of supply equipment work.
Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely illustrative of, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art
Member can make numerous variations or repair to these embodiments on the premise of without departing substantially from principle of the present utility model and essence
Change, but these changes and modification each fall within the scope of protection of the utility model.
