In one embodiment, photovoltaic production equipment maintenance provided by the embodiments of the present application and detection method include following step
It is rapid:
S100, the device controller 11 detect the operating mode of photovoltaic production equipment.
In this step, the device controller 11 may be implemented the selection to the operating mode of the photovoltaic production equipment and
Detection.The operating mode of the photovoltaic production equipment 10 may include automatic process mode, MANUAL CONTROL mode or detection maintenance
Three kinds of operating modes of mode.When the photovoltaic production equipment 10 is in different operating modes, technological parameter can be used and be added
Close or non-encrypted treating method.
S200, if photovoltaic production equipment is in non-automatic technology pattern, the device controller 11, which is sent, closes technique
The control instruction of parameter encryption, so that the photovoltaic production equipment is in non-encrypted state.
In this step, if photovoltaic production equipment is in non-automatic technology pattern, can by the device controller 11 to
The programmable logic controller (PLC) 12 sends the control instruction for closing technological parameter encryption.The programmable logic controller (PLC)
12 make the photovoltaic production equipment be in non-encrypted state.Here non-encrypted state refer to no longer to technological parameter into
Row encryption, i.e., the technological parameter that the described photovoltaic production equipment 10 executes can be acquired.
S300, if photovoltaic production equipment is in automatic process mode, the device controller 11 sends to terminate and hold
Row technology controlling and process instruction, so that the photovoltaic production equipment closes the automatic process being carrying out, into maintenance and detection rank
Section.
In this step, if photovoltaic production equipment is in automatic process mode, it can be generated by the device controller 11
Termination is carrying out technology controlling and process instruction.It sends to terminate to the technique actuator 13 by the device controller 11 and hold
The instruction of row technology controlling and process.The technique actuator 13 is obtained to terminate and is carrying out after technology controlling and process instruction, will be terminated
The automatic process of execution.Specific steps when the technique actuator 13 terminates the automatic process being carrying out are not construed as limiting.Than
Such as, the technological parameter for the automatic process that the technique actuator 13 can be carrying out is reset, or the institute that will be carrying out
The power-off of technique actuator 13 is stated to stop working.
In the embodiment of the present application, the photovoltaic production equipment maintenance and detection method include detecting the work of photovoltaic production equipment
Operation mode.If photovoltaic production equipment is in non-automatic technology pattern, the control instruction for closing technological parameter encryption is sent.
If photovoltaic production equipment is in automatic process mode, sends termination and be carrying out technology controlling and process instruction, so that the photovoltaic
