Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0021] Figures 1-2A flowchart illustrating an automated testing method based on air conditioning differential pressure start-up according to the present invention is shown. The method includes: S11 controls the compressor speed of the outdoor unit of the air conditioner and reads the pressure difference between the exhaust and intake of the outdoor unit. S12, based on the pressure difference reaching the pressure difference threshold, control the start of the compressor of the outdoor unit of the air conditioner to obtain the compressor start status; S13, based on the successful startup of the press, control the oscilloscope to test the press and obtain the test results.
[0022] It should be noted that the step number "S1N" in this manual does not represent the sequential order of the automated test method based on air conditioning differential pressure start-up. The following details will explain further. Figure 3 This invention describes an automated testing method based on air conditioning differential pressure start-up. Furthermore, the execution entity of this invention can be a monitoring system, such as a computer and monitoring software, to control and monitor the compressor and oscilloscope.
[0023] Step S11: Control the compressor speed of the outdoor unit of the air conditioner and read the pressure difference between the exhaust and intake of the outdoor unit.
[0024] In this embodiment, controlling the compressor speed of the outdoor unit of the air conditioner and reading the pressure difference between the exhaust and intake of the outdoor unit includes: controlling the compressor speed of the outdoor unit to a speed threshold; and based on the compressor speed reaching the speed threshold, controlling the compressor speed to a first preset value and reading the pressure difference between the exhaust and intake of the outdoor unit.
[0025] It should be noted that the speed threshold can be set according to the compressor type of the outdoor air conditioning unit involved, such as 70 rpm, without further limitation here. In addition, the first preset value is 0, so that when the compressor speed reaches 70 rpm, its speed is controlled to 0, so that the compressor stops working. At this time, the pressure difference (Pd-Ps) between the exhaust Pd and the intake Ps decreases. The pressure difference value is read, and when the pressure difference value reaches the pressure difference threshold, the compressor is controlled to start to perform a compressor start-up test to confirm whether the compressor can start successfully.
[0026] To elaborate further, controlling the compressor speed of the outdoor unit of the air conditioner to a speed threshold includes: monitoring the compressor speed of the outdoor unit; and controlling the compressor speed to the speed threshold. It should be noted that by monitoring the compressor speed of the outdoor unit, the compressor can be stopped promptly when the speed threshold is reached, thereby allowing the pressure difference between the exhaust gas pressure (Pd) and the intake gas pressure (Ps) to be read.
[0027] In one optional embodiment, before controlling the compressor speed of the outdoor unit of the air conditioner and reading the pressure difference between the exhaust and intake of the outdoor unit, the method includes: determining whether a preset number of tests has been reached; if so, adjusting the pressure difference threshold according to a preset pressure difference value adjustment rule, controlling the compressor speed of the outdoor unit of the air conditioner, and reading the pressure difference between the exhaust and intake of the outdoor unit of the air conditioner; wherein the preset pressure difference value adjustment rule is used to limit the value of the pressure difference threshold to be adjusted according to a preset value; otherwise, controlling the compressor speed of the outdoor unit of the air conditioner and reading the pressure difference between the exhaust and intake of the outdoor unit of the air conditioner.
[0028] It should be added that the preset differential pressure adjustment rule is used to limit the differential pressure threshold to be adjusted at least seven times, and to adjust by a preset value each time the preset number of tests is reached. Furthermore, the number of preset values needs to be determined based on the number of times the differential pressure threshold is adjusted. For example, if the differential pressure threshold is adjusted seven times, then the preset values are eight. The pressure difference is set in units of 1 kgf / cm², and the corresponding preset values can be 1 bar, 2 bar, 3 bar, 4 bar, 5 bar, 6 bar, 7 bar, and 8 bar. The specific values can be set according to actual design requirements and prior experience; no further limitations are made here.
[0029] In addition, at each differential pressure threshold, the preset number of tests needs to be repeated. The preset number of tests can be set according to actual design requirements, such as 5 times. No further limitation is made here. By repeatedly executing steps S11-S13 at each differential pressure threshold according to the preset number of tests, the compressor start-up success rate at the corresponding differential pressure threshold can be determined.
[0030] Step S12: Based on the pressure difference value reaching the pressure difference threshold, control the start of the compressor of the outdoor unit of the air conditioner to obtain the compressor start status.
[0031] It should be added that when the pressure difference reaches the pressure difference threshold, the compressor is started to perform a compressor start-up test to confirm whether the compressor can start successfully. Additionally, after obtaining the compressor start-up status, the process includes: determining whether the compressor start-up was successful or failed, and recording this information to facilitate subsequent determination of the compressor start-up success rate.
[0032] Step S13: Based on the successful startup of the press, control the oscilloscope to test the press and obtain the test results.
[0033] In this embodiment, controlling an oscilloscope to test the press and obtaining test results includes: controlling the oscilloscope to test the press and obtaining the press current waveform; determining whether the press current waveform is normal and obtaining test results.
[0034] It should be noted that a normal press current waveform is a single waveform. Therefore, when the press current waveform is different from the normal waveform, it can be determined that the press current waveform is abnormal. In addition, the normality of the press current waveform can also be determined by whether the current value in the press current waveform is abnormal.
[0035] In addition, after the press starts successfully, the press is tested by controlling an oscilloscope. The current waveform of the press obtained by the oscilloscope test is used to confirm whether the press started smoothly and whether the press operation is normal.
[0036] In one optional embodiment, after determining whether the preset number of tests has been reached, the method includes: evaluating the test status of the compressor start-up test based on the test results obtained from the tests at the same differential pressure threshold, based on the preset number of tests being reached.
[0037] Furthermore, based on the test results obtained from the same differential pressure threshold test, the test status of the compressor start-up test is evaluated, including: determining whether the compressor current waveform of the corresponding test result is normal based on the test results obtained from the same differential pressure threshold test; evaluating the test status of the compressor start-up test based on whether the compressor current waveform is normal; if the compressor current waveform is normal, the corresponding test status is determined to be a successful test; otherwise, the corresponding test status is determined to be a failed test; and determining the test success rate of the corresponding differential pressure threshold based on the test status of all test results obtained from the same differential pressure threshold test.
[0038] In an optional embodiment, since the compressor startup status can be obtained, the compressor startup success rate can also be determined based on the compressor startup status; accordingly, after determining the test success rate of the corresponding differential pressure threshold based on the test status of all test results obtained from the same differential pressure threshold test, the method includes: evaluating the test results based on the compressor startup success rate and the test success rate.
[0039] In one optional embodiment, the oscilloscope is a programmable oscilloscope, which includes, before controlling the oscilloscope to test the press based on the successful start-up of the press, generating a programming language for controlling the oscilloscope to test the press according to the control timing of the oscilloscope; wherein the control timing of the oscilloscope includes starting to work after the press is successfully started and stopping to work after the test results are obtained; and using the programming language to automatically control the start and stop of the oscilloscope.
[0040] It should be added that the oscilloscope is connected to the outdoor unit of the air conditioner so that it can be controlled to test the compressor of the outdoor unit.
[0041] In summary, this embodiment of the invention controls the compressor speed of the outdoor unit of the air conditioner to read the pressure difference between the exhaust and intake air of the outdoor unit. Based on the change in the pressure difference, it determines whether to start the compressor when the pressure difference reaches the pressure difference threshold to perform a compressor start-up test, confirming whether the compressor can start successfully. After successful compressor start-up, it controls an oscilloscope to test the compressor to further detect the compressor start-up status, ensuring that the compressor starts normally. This achieves automated testing of pressure difference start-up, freeing up manpower and improving test accuracy.

The automated testing system based on air conditioning differential pressure start-up described below can be referred to in correspondence with the automated testing method based on air conditioning differential pressure start-up described above.
[0043] Figure 4 A schematic diagram of an automated testing system based on air conditioning differential pressure start-up is shown. The system includes: The speed control module 41 controls the compressor speed of the outdoor unit of the air conditioner and reads the pressure difference between the exhaust and intake of the outdoor unit. The compressor control module 42 controls the compressor of the outdoor unit of the air conditioner to start based on the pressure difference value reaching the pressure difference threshold, and obtains the compressor start-up status; Test control module 43, based on the successful startup of the press, controls the oscilloscope to test the press and obtain the test results.
[0044] In this embodiment, the speed control module 41 includes: a speed control unit, which controls the compressor speed of the outdoor unit of the air conditioner to a speed threshold; and, based on the compressor speed reaching the speed threshold, controls the compressor speed to a first preset value and reads the pressure difference between the exhaust and intake of the outdoor unit of the air conditioner.
[0045] It should be noted that the speed threshold can be set according to the compressor type of the outdoor air conditioning unit involved, such as 70 rpm, without further limitation here. In addition, the first preset value is 0, so that when the compressor speed reaches 70 rpm, its speed is controlled to 0, so that the compressor stops working. At this time, the pressure difference (Pd-Ps) between the exhaust Pd and the intake Ps decreases. The pressure difference value is read, and when the pressure difference value reaches the pressure difference threshold, the compressor is controlled to start to perform a compressor start-up test to confirm whether the compressor can start successfully.
[0046] Furthermore, the speed control unit includes: a speed monitoring subunit, which monitors the compressor speed of the outdoor unit of the air conditioner; and a speed control subunit, which controls the compressor speed to a speed threshold. It should be noted that by monitoring the compressor speed of the outdoor unit, the compressor can be stopped promptly when it reaches the speed threshold, thereby allowing the pressure difference between the exhaust gas pressure Pd and the intake gas pressure Ps to be read.
[0047] In an optional embodiment, the system further includes: a test count determination module, which determines whether a preset test count has been reached before controlling the compressor speed of the outdoor unit and reading the pressure difference between the exhaust and intake air of the outdoor unit. If the preset test count has been reached, the differential value adjustment module adjusts the differential pressure threshold according to a preset differential pressure value adjustment rule, and the speed control module controls the compressor speed of the outdoor unit and reads the pressure difference between the exhaust and intake air of the outdoor unit. The preset differential pressure value adjustment rule is used to limit the value of the differential pressure threshold to be adjusted according to a preset value. Otherwise, the speed control module controls the compressor speed of the outdoor unit and reads the pressure difference between the exhaust and intake air of the outdoor unit. It should be noted that the preset differential pressure adjustment rule is used to limit the differential pressure threshold to be adjusted at least seven times, and to be adjusted according to a preset value each time the preset test count is reached. Furthermore, the number of preset values needs to be determined based on the number of times the differential pressure threshold is adjusted. For example, if the differential pressure threshold is adjusted seven times, then there are eight preset values. The differential pressure is set in units of 1 kgf / cm2, and the corresponding preset values can be 1 bar, 2 bar, 3 bar, 4 bar, 5 bar, 6 bar, 7 bar, and 8 bar. The specific values can be set according to actual design requirements and prior experience, and no further limitations are made here.
[0048] In addition, at each differential pressure threshold, the preset number of tests needs to be repeated. The preset number of tests can be set according to actual design requirements, such as 5 times. No further limit is made here. By automating the compressor startup test at each differential pressure threshold according to the preset number of tests, the startup success rate of the compressor at the corresponding differential pressure threshold can be determined.
[0049] It should be added that when the pressure difference reaches the pressure difference threshold, the compressor is controlled to start to perform a compressor start-up test and confirm whether the compressor can start successfully. In addition, the system also includes a result recording module, which, after obtaining the compressor start-up status, determines whether the compressor start-up was successful or failed, and records the result to facilitate subsequent determination of the compressor start-up success rate.
[0050] The test control module 43 includes: a current waveform acquisition unit, which controls an oscilloscope to test the press and obtain the press current waveform; and a test result acquisition unit, which determines whether the press current waveform is normal and obtains the test result.
[0051] It should be noted that a normal press current waveform is a single waveform. Therefore, when the press current waveform is different from the normal waveform, it can be determined that the press current waveform is abnormal. In addition, the normality of the press current waveform can also be determined by whether the current value in the press current waveform is abnormal.
[0052] In addition, after the press starts successfully, the press is tested by controlling an oscilloscope. The current waveform of the press obtained by the oscilloscope test is used to confirm whether the press started smoothly and whether the press operation is normal.
[0053] In an optional embodiment, the test control module 43 is further configured to: after determining whether the preset number of tests has been reached, evaluate the test status of the compressor start-up test based on the test results obtained from the tests at the same differential pressure threshold, based on the preset number of tests being reached.
[0054] Furthermore, the test control module 43 includes: an anomaly judgment unit, which determines whether the compressor current waveform of the corresponding test result is normal based on the various test results obtained from the test of the same differential pressure threshold; a situation evaluation unit, which evaluates the test situation of the compressor start-up test based on whether the compressor current waveform is normal, and determines that the corresponding test situation is a test success if the compressor current waveform is normal; otherwise, it determines that the corresponding test situation is a test failure; and a test success rate evaluation unit, which determines the test success rate of the corresponding differential pressure threshold based on the test situation of all test results obtained from the test of the same differential pressure threshold.
[0055] In an optional embodiment, the system further includes: a startup success rate evaluation module, which determines the startup success rate of the compressor based on the startup status after obtaining the compressor startup status; correspondingly, the system further includes: a comprehensive evaluation module, which evaluates the test results based on the startup success rate and the test success rate after determining the test success rate of the corresponding differential pressure threshold based on the test status of all test results obtained from the test of the same differential pressure threshold.
[0056] In an optional embodiment, the oscilloscope is a programmable oscilloscope. The system further includes: a language generation module, which generates a program language for controlling the oscilloscope to test the press based on the control timing of the oscilloscope before controlling the oscilloscope to test the press based on the successful start-up of the press; wherein the control timing of the oscilloscope includes starting to work after the press is successfully started and stopping to work after the test results are obtained; and a test control module 43, which uses the program language to automatically control the start and stop of the oscilloscope.
[0057] It should be added that the oscilloscope is connected to the outdoor unit of the air conditioner so that it can be controlled to test the compressor of the outdoor unit.
[0058] In summary, this embodiment of the invention controls the compressor speed of the outdoor unit of the air conditioner through a speed control module to read the pressure difference between the exhaust and intake air of the outdoor unit. Based on the change in the pressure difference, the compressor control module controls the compressor to start when the pressure difference threshold is reached to perform a compressor start-up test, confirming whether the compressor can start successfully. After the compressor starts successfully, the test control module controls an oscilloscope to test the compressor to further detect the compressor start-up status and ensure that the compressor starts normally. This achieves automated testing of pressure difference start-up, freeing up manpower and improving test accuracy.
