Reception interrupt, into interruption after read command information first, and using condition judgment Programmable detection instruction letter as shown in Figure 4
Number, the instruction according to representated by command signal is handled accordingly.If the instruction representated by command signal is signal call number
More new command, then preserve former call number and read new call number, so that DSP data transmission program is used for the signal that judges to send
Data；If the instruction representated by command signal instructs for the modification of control parameter, block pwm pulse, receives new control at once
Parameter value processed simultaneously carries out online updating.Whole reception process removes interrupt identification after terminating.That is, controller 100 is connecing
When receiving parameter setting information, the instruction in parameter setting information is first received, then receive the relevant parameter in parameter setting information.And
Conveniently monitored parameter type can be extended according to actual needs above by the program frame using condition judgment mode.
It is preferred that, data processing module 202 be used to sending after handling the parameter setting information of outside input to
During VISA modules 201, specifically for：
Completed in initialization and the periodic scan control command status of front panel 203 obtains the result that command status updates
Afterwards, the instruction updated is judged；
If the instruction updated is the more new command of signal call number, new measured signal is sent by VISA modules 201
Call number to controller 100, then wait controller 100 to respond；
If the instruction updated instructs for the modification of control parameter, the modification instruction of control parameter is passed through into VISA modules
201 send to controller 100；Then controller 100 is waited to respond；
After the modification instruction of the response control parameter of device 100 to be controlled, new control parameter is sent by VISA modules 201
To controller 100.
It is preferred that, the control parameter includes：PI regulation parameters, overvoltage protection value, under-voltage protection value and overheat protector value.
Specifically, carrying out respective handling to the control parameter of inverter according to parameter setting information with processing module 102
Corresponding, LabVIEW monitoring softwares in data processing module 202, i.e. host computer 200, internal workflow may refer to
Fig. 5.The LabVIEW monitoring softwares carry out the read-write operation of serial ports by VISA modules 201, to VISA modules in host computer 200
201 are initialized, and are realized and the identical communication protocol of SCI modules 103 in controller 100.LabVIEW monitoring softwares are normally transported
After row, command status array of each cycle period scanning from control front panel 203, by with oldState array contrasting detection
Whether command status changes；Data receiving state is kept if command status does not change, is continued to from control
Operational factor that device 100 is sent simultaneously carries out processing and shown；Instruction if command status changes according to representated by instruction contains
Justice realizes the selection of the processing routine of command adapted thereto using condition judgment program.For the more new command of signal call number, directly
The call number of new measured signal is sent to controller 100, waits the response of controller 100 to set up communication, receives controller 100
Shown after the measured signal sent, caching process with numerical value or wave form.Modification for control parameter is instructed, first
The modification command signal of control parameter is sent to controller 100, notification controller 100 has control parameter to need modification, controller
100 receive and are made an immediate response after command signal, and carry out the preparation for receiving new parameter, and LabVIEW monitoring softwares receive controller 100
Response instruction after, new control parameter is sent immediately to controller 100, controller 100, which passes through to receive to interrupt, receives new control
Parameter processed and online updating.PI parameter values, overvoltage protection value, under-voltage protection value, excess temperature can be protected by LabVIEW monitoring softwares
Shield value is configured and updated, and is not limited merely to this.It can facilitate according to reality by using the program frame of condition judgment mode
Border needs to be extended monitored parameter type.
