Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present disclosure, the technical solution in the embodiment of the present disclosure is carried out clear, complete
Site preparation description.
Fig. 1 is the flow diagram according to the method for the setting frequency converter identity of some embodiments of the disclosure.
As shown in Figure 1, the method for the embodiment includes: step 110~160.
In step 110, display obtains the initial identity of frequency converter.
Wherein, the initial identity of frequency converter is default identity mark, such as can be arranged before factory.Display can
The initial identity of frequency converter is known with the factory parameter according to frequency converter.
In step 120, display obtains the new identity of frequency converter.
Wherein, the new identity of frequency converter can be obtained from the configuration information of user setting.New identity
Such as can be specified by user, user is that different frequency converters specifies different new identity, to complete in frequency converter
The identity of frequency converter can be distinguished after identity setting.
In step 130, frequency converter is with initial identity incoming communication network.
Frequency converter for example can normally can not access network in access network for the first time or according to original identity
In the case of, with initial identity incoming communication network.
In addition, if thering are multiple frequency converters to need that identity is arranged, in frequency converter identity setup phase, these changes
Although frequency device all connecting communication networks, the same time only has a frequency converter with initial identity incoming communication network.Example
Such as, the same time only allows one of frequency converter to power on, other frequency converters do not power on.
In step 140, display sends control command to frequency converter according to the initial identity of frequency converter, to indicate to become
It is new identity that frequency device, which resets identity,.
Wherein, control command carries the new identity of frequency converter, and the destination address of control command is the first of frequency converter
Beginning identity, to enable control command to be addressed to corresponding frequency converter using initial identity.
In step 150, frequency converter receives the control command that display is sent.
Wherein, control command for example can be by display encryption.Correspondingly, frequency device is needed to received control
System order is decrypted.Cipher mode for example can be by the way of display and frequency converter agreement, and frequency converter is according to corresponding
Manner of decryption is decrypted.So that control command is not easy by data interference other similar in bus.
In step 160, for frequency converter according to the instruction of control command, resetting identity is new identity.
In the above-described embodiments, display sends control command to frequency converter according to the initial identity of frequency converter, with
It is new identity that instruction frequency converter, which resets identity, does not have the case where hardware address dial-up interface in frequency converter
Under, the identity information of each frequency converter can be still set, so that the identity information using each frequency converter can distinguish frequency conversion
The identity of two frequency converters of Screw chiller.
Be advantageous in that using the identity information of display setting frequency converter: display uses DC power supply (usually
24V), frequency converter uses three-phase alternating current (380V), and display can be powered by inversion, does not need other power supplys, and
Display and frequency converter use CAN communication, do not need communication switching processing, in addition, in frequency conversion screw unit, display and
The connection line of each frequency converter can be constant, without additional processing of relocating.
In addition, the disclosure can also confirm whether the setting of frequency converter identity information succeeds.Below with reference to following embodiments
It is described.
Fig. 2 is the flow diagram according to the method for the setting frequency converter identity of some embodiments of the disclosure.
As shown in Fig. 2, on the basis of the method for embodiment embodiment shown in Fig. 1, further includes: step 110~160.
In step 270, frequency converter returns to the identity of setting by initial identity to display, so that display
Device determines whether frequency converter identity setting succeeds by the consistency of the identity and new identity that return.
In some embodiments, frequency converter can return to the identity of setting within a preset time, so as to display energy
It is enough to judge whether frequency converter identity setting succeeds in time.If display fails the setting for receiving frequency converter return in time
Identity, after reaching preset time, display can re-execute the steps 140, i.e. retransmission control command, to refer to again
Showing that frequency converter resets identity is new identity.
For example, then frequency converter, reads new identity write-in memory so that its identity information is arranged from memory
The identity read from memory is returned to display by the identity of setting, to determine that frequency converter identity is arranged
Whether succeed.Error when to prevent identity to be written.
Wherein, new identity comes into force after frequency converter is restarted.Except new identity Pending The Entry Into Force, frequency converter is still
So communicated with initial identity with display.
In step 280, display receives the identity for the frequency converter setting that frequency converter returns, and by the identity mark of return
Know and is compared with the new identity of local record.
In step 280a, display determines frequency conversion under the identity and new identity unanimous circumstances of return
Device identity is arranged successfully.
In step 280b, display determines and becomes in the case where the identity of return and new identity are inconsistent
Frequency device identity setup failed.
In addition, display can be sent out the prompt information of setting result, for example, " being arranged successfully " and " setup failed ",
It allows users to intuitively determine setting result.
Above-described embodiment is able to confirm that whether the setting of frequency converter identity information succeeds.
The method of above-mentioned setting frequency converter identity, operates very simply, and be not easy for a user
It is wrong.
For example, with reference to frequency converter identity set interface schematic diagram shown in Fig. 3 a, user only needs to select to need to set
The frequency converter set, and click determination, display will obtain automatically the frequency converter in configuration information initial identity and
New identity, and send control command.Display issues in the case of Fig. 3 b and 3c are arranged to function and setup failed respectively
Prompt information, for example, " being arranged successfully, after frequency converter power-off restarting, identity comes into force！", " setup failed please be reseted！"
