Method heat dissipation.
Each ventilator is opened in a different order in setting ventilation assembly 402, when reaching unlocking condition, according to default
Opening sequence open wherein one group or multiple groups ventilator.In order to solve ventilator failure lead to not be aerated in time it is scattered
Heat, while maintaining easily personnel or backstage personnel know the state of ventilator, in step s 201, control assembly 404 obtains
The default opening sequence of two groups of ventilator, the mode of acquisition include read from self EMS memory the opening sequence table of each ventilator,
Or solicited message is sent to background service center, opening for each ventilator is obtained from the return information that background service center is fed back
Open sequence.
In step S202, control assembly 404 obtains the operating status of the ventilator of the first opening sequence, the operating status
It is in normal condition, malfunction, lost contact state etc. including the ventilator, the mode of acquisition includes the fortune read in the ventilator
Row data obtain the ventilator in the operation information of a upper runing time from the operation data, judge that the ventilator is with this
It is no to be in normal condition.
In step S204, if the ventilator of first opening sequence is in normal condition, then the transmission of control assembly 404 is opened
Instruction is opened to the ventilator of first opening sequence, to open the ventilator of first opening sequence, if first opening sequence
Ventilator be in abnormal condition, that is, be in malfunction or lost contact state etc., then control assembly 404 obtain second open it is suitable
The operating status of the ventilator of sequence.Further, in step S204, control assembly 404 is also according to the logical of the first opening sequence
The relevant information of wind device generates Fisrt fault information, which is sent to background service center, other specified ends
End or equipment, the Fisrt fault information include ventilator location information, number information and the failure letter of first opening sequence
Breath etc..Other designated terminals or equipment include O&M terminal, mobile phone etc., the side that Fisrt fault information is pushed according to information
Formula is shown.
In step S206, if the ventilator of the second opening sequence is in normal condition, control assembly 404, which is sent, is opened
The ventilator for instructing second opening sequence, if the ventilator of second opening sequence is in malfunction, then control assembly 404
The second fault message is generated, which is sent to background service center, other designated terminals or equipment, this
Two fault messages are used to prompt ventilator all in the ventilation assembly of current photovoltaic curtain wall component to be in malfunction, the light
Volt curtain wall component can not radiate.
In the present embodiment, control assembly 404 obtains the default opening sequence of each ventilator, presets opening sequence according to this
The operating status for obtaining each ventilator in sequence respectively is determined to the ventilator opened according to the operating status, if ventilation
Device is in malfunction and then generates fault message informing related personnel, and the present embodiment is opened according to the virtual condition of ventilator
It opens, solves the problems, such as to lead to heat dissipation failure because of ventilator failure, while generating fault message, facilitate operation maintenance personnel to generation
The ventilator of failure is safeguarded, photovoltaic curtain wall component is avoided to cause photovoltaic cell capable of generating power efficiency because of temperature liter because of ventilator failure
It is high and reduce and the risk of glass rupture.Specifically, in the present embodiment, control assembly 404 in addition to generate fault message it
Outside, alarm command can be generated simultaneously, and the alarm assemblies which is used to control in photovoltaic curtain wall system issue alarm, to rise
To warning function, operation maintenance personnel at the scene is notified in time.
Fig. 3 show another embodiment of the present invention provides heat dissipating method, control assembly 404 obtain photovoltaic curtain wall component
