Abstract
A frequency converter on-load system comprises a host computer and an on-load test board. The host computer and the on-load test board are connected through an RS485 network. The host computer has six on-load testing modules. The RS485 network comprises a USB-RS485 converter connected with the USB interface of the host computer and an RS485 communication interface connected with the on-load test board. The on-load test board is provided with six frequency converter interfaces. Each frequency converter interface is corresponding to one on-load testing module. Each frequency converter is connected with a DA or DB port of a frequency converter to be tested. The host computer and the on-load test board are remotely communicated through the RS485 network. The on-load test board performs automatic testing after receiving test instructions of the host computer. The human labor intensity can be lowered.

Embodiment
Frequency converter band loading system, comprise that host computer and band carry test board, it is characterized in that: host computer and band carry test board by the RS485 network connection, host computer has six bands and carries test module, the RS485 network comprises the USB-RS485 converter that is connected with the USB interface of host computer, and carries the RS485 communication interface that is connected of test board with band; Band carries a test board and is provided with six frequency converter interfaces, and the corresponding band of each frequency converter interface carries a test module, and the frequency converter interface is connected with DA or the DB port of frequency converter to be tested.
As shown in Figure 1, the computing machine that upper computer software is housed, carries specifying frequency converter to be with respectively to a plurality of frequency converters on the microscope carrier by the RS485 network connection, resets, startup and shut-down operation, realizes that man-to-man band carries control; This upper computer software also can carry out the full cut-off operation to frequency converter, makes simultaneously response command of all online frequency converters, realizes the control of one-to-many.
The computing machine that upper computer software is housed connects RS485 communication bus one end by the USB-RS485 converter, and this RS485 communication bus other end is connected to the total interface of RS485 communication with microscope carrier.
As shown in Figure 2, the band microscope carrier provides seven RS485 communication interfaces, and total interface is connected with the RS485 bus, and connects other six sub-interfaces, and sub-interface connects DA, the DB port of frequency converter.Described band microscope carrier has six stations, can place simultaneously six frequency converters, and each station has input port R, S, T and output port U, V, the W of power supply, grounding ports, power switch, Current Control button, Control of Voltage button.
As shown in Figure 3, host computer is provided with six bands and carries test module, and realization is carried the long-range band of six frequency converters simultaneously.The operation interface of host computer is provided with band and carries, resets, starts, stops and the full cut-off button, realizes the long-range band of frequency converter is carried.The operation interface of host computer can also show in real time that type, band year time, machine bar code, the band of frequency converter carry station, output frequency, output current, busbar voltage, temperature value and failure code.
After connecting upconverter, press start button, if show data then prove the inverter communication success, the beginning Real Time Monitoring, otherwise show " without response ".Press band and carry button, frequency converter switches to the Communication Control pattern, and bring into operation, output frequency, output current, busbar voltage, temperature value, failure code, frequency converter type, the band that shows in real time carried the data such as time, machine bar code and band year station and preserved every 2 seconds.In operational process, can automatically carry out a rotating and switch.Band carries in the process needs to carry out overload measurement, can show failure code, presses reset button and resets, and reruns by start button again, arrives the predetermined band time of carrying to press the stop button bundling article and carry.
The data plot of preserving with loading system as shown in Figure 4.
In the utility model, host computer carries test board with band and carries out telecommunication by the RS485 network, band carries and to carry out automatic test after test board receives the test instruction of host computer, realize that long-range band carries and Real Time Monitoring, made things convenient for staff's centralized and unified operation, save a large amount of monitoring instruments, reduced hand labor intensity.
The described content of this instructions embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reaches the equivalent technologies means that design can be expected according to the utility model in those skilled in the art.
