The measurement of these items can be achieved by the prior art. Those skilled in the art can test some of the items or add new test items as needed, and the modification itself does not require creative efforts.
Example 1
In this embodiment, the structure of the frequency converter testing system is shown in fig. 1, and the frequency converter testing system mainly includes a controller and a plurality of testing terminals, and parts such as a power supply circuit and a protection structure are not related to the technical problem to be solved by this embodiment, and therefore are not shown in fig. 1.
Each test port shown in fig. 1 is a module including necessary components such as a port, a conversion component, and a communication component. The structure of a testing end is shown in fig. 2, wherein, the port is used for matching with the frequency converter to be tested in physical aspects such as appearance, electrical characteristics and the like; conversion means for converting the measured original signal into a computer-readable signal or effecting conversion of physical quantities such as voltage/current signals into signals representing the magnitude of power, and temperature into level signals or the like; the communication unit has data processing, memory and communication capabilities and is capable of buffering the signals converted by the conversion unit and then uploading them to the controller at regular times or upon request from the controller.
In this embodiment, as shown in fig. 3, a plurality of ports may be arranged in one testing end, and the ports are respectively connected to corresponding ports on the frequency converter, so as to respectively obtain parameters such as the under-voltage and the braking voltage.
In this embodiment, a single chip microcomputer of an STM32 architecture may be used as a controller, and the controller may be programmed and configured such that the operating state of the controller includes a plurality of data acquiring states and a data processing state, and the controller is switchable between the data acquiring states, that is, after a work task is completed (or a work task is not completed and a specific trigger condition is detected) in one data acquiring state, the controller is switched to another data acquiring state or data processing state to operate.
When the frequency converter testing system in the embodiment is used, a worker firstly connects the frequency converter to be tested to each testing end, and starts the frequency converter to enable the frequency converter to be in an idle state. A worker issues a test task to the controller in a mode of writing a program into the controller, triggering the controller by using human-computer interaction equipment such as a touch screen and the like. The content of the test task is mainly as follows: it is necessary to test several converters, to which test terminals the converters are connected, what items need to be tested for each converter.
The controller acquires the test task, reads the address of the test end connected with the frequency converter from the test task, sets the test end not connected with the frequency converter to be in an idle state, and then determines that several data acquisition states are needed in the test process and an acquisition rule in each data acquisition state.
In this embodiment, the number of the set data obtaining states is the same as the number of items to be tested on the frequency converter. In this embodiment, the items to be tested are set to be under-voltage, power, software version, and over-voltage upper limit, that is, the number of the items to be tested is 4, and therefore, the number of the data acquisition states is also 4. In this embodiment, the number of frequency converters to be tested is 3, and they are connected to the test terminal 1, the test terminal 2, and the test terminal 3, respectively.
In this embodiment, the obtaining rule of each data obtaining state refers to a type of test data obtained by each test terminal in the data obtaining state. The acquisition rule set in the present embodiment is shown in table 1.
TABLE 1
Table 1 can be understood as:
in a data acquisition state 1, a controller acquires under-voltage data from a connected frequency converter through a test end 1, acquires power data from the connected frequency converter through a test end 2, and acquires software version data from the connected frequency converter through a test end 3;
in the data acquisition state 2, the controller acquires power data from the connected frequency converter through the test end 1, acquires under-voltage data from the connected frequency converter through the test end 2, and acquires over-voltage upper limit data from the connected frequency converter through the test end 3;
in a data acquisition state 3, the controller acquires software version data from the connected frequency converter through the test terminal 1, acquires overvoltage upper limit data from the connected frequency converter through the test terminal 2, and acquires power data from the connected frequency converter through the test terminal 3;
in the data acquisition state 4, the controller acquires overvoltage upper limit data from the connected frequency converter through the test terminal 1, acquires software version data from the connected frequency converter through the test terminal 2, and acquires undervoltage data from the connected frequency converter through the test terminal 3.
By sequentially executing the data acquisition state 1, the data acquisition state 2, the data acquisition state 3 and the data acquisition state 4, the frequency converters connected to each test terminal can be respectively tested, and test data of a required test item can be obtained for each frequency converter. Table 1 is only an example, and those skilled in the art can generalize the conditions of table 1 to the conditions of testing more frequency converters, testing more items for each frequency converter, testing different items for each frequency converter, and the like without creative labor, so that the frequency converter testing system in the embodiment has a stronger adaptability.
The frequency converter testing system and the control algorithm thereof in the embodiment have the advantages that the simultaneous testing of different frequency converters is realized on the same equipment, and the testing efficiency of the frequency converters is improved in multiples on the basis of not increasing the use cost greatly; by setting the acquisition rule in each data acquisition state and reasonably configuring the acquisition rule, the frequency converter testing system can realize the testing of various testing items. For example, the test requirements of the items such as power, undervoltage, overvoltage upper limit, software version and the like tested in the embodiment are different, wherein the test of the software version is simplest, and only a query instruction needs to be sent to the frequency converter and feedback information needs to be received; the tests of undervoltage, overvoltage upper limit and the like have higher requirements on the voltage bearing capacity of the frequency converter test system; the power test requires that a frequency converter test system bears higher voltage and higher current, and needs to perform signal conversion, filtering and other processing, and the requirements on hardware and software are the highest among the 4 test items; according to the embodiment, through reasonable configuration of the acquisition rule, different items are tested for different frequency converters in the same data acquisition state respectively, hardware resources and software resources of the frequency converter testing system are fully utilized, and therefore even if the frequency converter testing system is upgraded and modified in the later period, the frequency converter testing system can test more complicated items and test more frequency converters at the same time, only part of hardware or software resources need to be added, the resources do not need to be added according to the scale capable of containing the frequency converters, and therefore the use cost is saved.
Table 1 shows that the number of data acquisition states executed is the same as the number of items to be tested, and actually, more data acquisition states may be set, so that there are at least two data states, and the items tested by the data states are the same, that is, at least two sets of data are tested for one test item in one test process, and at this time, statistical means such as calculating an average may be adopted to determine one data as a final test value, so as to reduce errors in a single test and improve the accuracy of the test.
After executing enough data acquisition states, the controller executes a data processing state once to collect the test data acquired in each data acquisition state, which specifically includes:
grouping the test data according to a test end used when the test data are obtained, so that a corresponding relation is formed between each group of the test data and one frequency converter; in each data acquisition state, when the test data is acquired through the test end, the address or the number of the test end and the test data are stored together, so that the test end from which the test data comes, namely the frequency converter to which the test data belongs, can be distinguished; and test data belonging to the same frequency converter are put in the same group.
Sequencing each test data in the same group according to the acquisition time; namely, the earlier obtained test data in the test data belonging to the same frequency converter are ranked in the front.
After completing the aggregation of the test data, the controller generates a test report. The test report may be presented in a table format, and the content of the test report may include: the serial number of the test task; the test data of each frequency converter and the acquisition time of each test data; normal range for each test data and normality assessment. After the controller generates the test report, the test report can be further uploaded to the cloud end for the administrator to look up.
The test items of each frequency converter and whether the functions of each frequency converter are normal can be intuitively displayed through the test report. The staff only needs to be connected to the converter test system with the converter manually and assigns the test task, and the test process can be realized automatically to converter test system and the test report is exported, and the staff can know the test result through reading the test report, has greatly reduced staff's work load, has improved staff's work efficiency.
