[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0023] Figure 1 A schematic diagram of the basic structure of an air conditioning unit testing device provided in one embodiment of the present application.
[0024] Reference Figure 1 As shown, the air conditioning unit testing device may include a unit identification unit 101 and a test control unit 102 .
[0025] In some embodiments, identity information may be pre-set for the air-conditioning unit to be tested. In one implementation, identity information may be set for each air-conditioning unit in the form of an identification code. Exemplarily, the identification code may be a barcode.
[0026] In some embodiments, after setting identity information for each air-conditioning unit, the identity information set for each air-conditioning unit (such as a barcode) can be stored inside the air-conditioning unit testing equipment, so that the air-conditioning unit testing equipment can know the identity relationship table corresponding to each air-conditioning unit and its identity information. When at least one air-conditioning unit 101 to be tested in the target area is tested by the air-conditioning unit testing equipment 102, the unit identification unit can quickly and accurately obtain the identity information of the current air-conditioning unit to be tested (i.e., the target unit) by identifying the barcode.
[0027] In some embodiments, when the identification code set for the air-conditioning unit is a barcode, the unit identification unit 101 can be a barcode scanning device, such as a barcode scanning gun. In response to the user's first control operation, the unit identification unit 101 scans the barcode of the currently processed air-conditioning unit to be tested, and sends the scanned data to the test control unit 102 through an interface with the test control unit 102, such as a Universal Serial Bus (USB) interface, and then the test control unit 102 matches the identity information of the currently processed air-conditioning unit to be tested in the pre-stored identity relationship table based on the received scanned data.
[0028] In other embodiments, the identity relationship table can also be stored on the unit identification unit 101 side, based on which the unit identification unit 101 can directly match the scan data to obtain the identity information of the currently processed air-conditioning unit to be tested. This application does not limit the method of obtaining the identity information of the currently processed air-conditioning unit to be tested.
[0029] In some embodiments, the identification code corresponding to the identity information of the air-conditioning unit to be tested can be stored or placed in a location that is convenient for the testing staff to scan. For example, it can be stored in a PC device where the staff works, and the identification code can be displayed on the display screen of the PC device; or the identification code can be printed on a portable card, which the staff can carry with them, thereby improving the convenience and flexibility of the scanning work. It should be noted that in other examples, the identification code can also be displayed in other ways, and this application does not limit the display method of the identification code.
[0030] In some embodiments, the air-conditioning unit testing equipment can be connected to at least one air-conditioning unit to be tested. When the staff scans the identification code through the unit identification unit, the identity information of the air-conditioning unit to be tested corresponding to the identification code is identified, such as "unit 000001", and then it can be determined that the currently identified air-conditioning unit to be tested is the target unit for this test.
[0031] Figure 2 A schematic diagram of scanning and identifying a target unit provided in one embodiment of the present application.
[0032] Reference Figure 2 As shown, the air-conditioning unit testing equipment is connected to the air-conditioning units D1 to D6 to be tested. After the staff scans the identification code C3 through the unit identification unit, the identity information of the air-conditioning unit to be tested corresponding to the identification code C3 is identified, that is, the identity information of the air-conditioning unit to be tested, for example, "unit 000003", and then determines that the air-conditioning unit to be tested with the identity information "unit 000003" is the target unit for this test.
[0033] In some embodiments, after determining the target unit for this test, the test control unit 102 may also send a control instruction to the target unit to control the target unit to execute a test process to obtain the test data of the target unit. The test process may include the following steps:
[0034] S101: The test control unit sends a control instruction to the target unit to control the target unit to execute the target test.
[0035] S102: The test control unit obtains the test data of the target unit according to the execution signal fed back by the target unit.
[0036] In some embodiments, the test control unit 102 can control the air conditioning unit to be tested to perform the target test, collect the execution signal fed back by the air conditioning unit to be tested, and then obtain the test data of the target unit based on the execution signal. Through the full-process automated testing method, the possibility of missed detection is reduced, and the efficiency of the air conditioning unit test and the data accuracy can be improved.
[0037] Figure 3 A schematic diagram of the structure of an air conditioning unit testing device provided in one embodiment of the present application.
[0038] Reference Figure 3 As shown, the air conditioning unit test equipment Figure 1 In addition to the unit identification unit 101 and the test control unit 102 shown, a human-machine interaction unit 103 , a data storage unit 104 and a power supply unit 105 may also be included.
[0039] In some embodiments, reference Figure 3 As shown, the test control unit 102 may specifically include a main control chip. To enable the test control unit to control the air-conditioning unit to be tested to perform the target test, the main control chip of the test control unit 102 may pre-burn the test software and control parameters to the control board of the air-conditioning unit through a communication interface. The communication interface may be an RS232 interface.
[0040] In some embodiments, when it is necessary to test the air-conditioning unit to be tested, after completing the identity identification of the currently processed air-conditioning unit to be tested and determining the target unit, the test control unit 102 (specifically, it can be the main control chip) sends a control instruction to the test software of the current air-conditioning unit to be tested (target unit), and controls the target unit to perform the target test based on the control instruction and with reference to the control parameters. Among them, after the test software of the air-conditioning unit to be tested receives the control instruction sent by the test control unit 102, it can control the air-conditioning unit to perform the target test based on the control parameters. Among them, it should be noted that, in one embodiment, the control instruction sent by the test control unit 102 to the test software of the air-conditioning unit to be tested can be a start instruction for instructing the air-conditioning unit to be tested to start executing the target test. After receiving the start instruction, the test software of the air-conditioning unit to be tested can execute a preset test program, thereby realizing the execution of one or more target tests in the process of executing the preset program. In another embodiment, the control instruction sent by the test control unit 102 to the test software of the air-conditioning unit to be tested may be multiple sub-control instructions, and each sub-control instruction corresponds to a target test, wherein each time the air-conditioning unit to be tested receives a sub-control instruction, it executes the corresponding target test based on the control parameters, and then executes multiple target tests in sequence through the above-mentioned paper type method.
[0041] In some embodiments, reference Figure 3 As shown, the human-computer interaction unit 103 is connected to the test control unit 102, and is used to send a detection start instruction to the test control unit in response to the user's second control operation. The test control unit triggers the execution of the test process based on the detection start instruction.
[0042] In some embodiments, the human-computer interaction unit 103 may include an LED indicator light and a touch screen. The LED indicator light is used to indicate the operating state of the test control unit 102 based on the first display state. Exemplarily, after the test control unit 102 starts to execute the test program, the LED indicator light can be controlled to switch to display a yellow light, which can indicate that the test control unit 102 is in operation. The touch screen can also display a control for the user to control the start of the test process. Exemplarily, the display name of the control on the touch screen can be "Start Test", and in response to a click operation on the "Start Test" space, a detection start instruction is sent to the test control unit 102 group. The test control unit 102 triggers the execution of the test process based on the detection start instruction.
[0043] In some embodiments, after completing the test of the target unit and obtaining the test data of the target unit, the test control unit 102 can also bind the identity information and test data of the same air-conditioning unit to form a test result based on the test data. Exemplarily, the identity information of the target unit is "unit 000003", and the test data of the target unit can be bound to the identity information "unit 000003" of the target unit to form a test result combining the test data and the unit identity information.
[0044] In some embodiments, the LED indicator light can also indicate the fault state of the currently tested air conditioning unit (target unit) based on the second display state. After completing the test of an air conditioning unit, the test result can also be indicated based on the color of the LED indicator light. If the test result shows that the air conditioning unit is normal, the LED indicator light is controlled to switch to display a green light. If the test result contains abnormal information or fault information, the LED indicator light is controlled to switch to display a red light. The user can quickly understand whether the test result contains abnormal information or fault information based on the color of the LED indicator light.
[0045] In some embodiments, the touch screen of the human-computer interaction unit 103 can be used to display the identification information and identification status of the crew identification unit 101. Exemplarily, when the crew identification unit 101 is performing identity identification, its identification status is identifying, and the current identification status can be displayed on the touch screen as "identifying", and when the crew identification unit 101 completes identity identification, the current identification status can be displayed on the touch screen as "identification completed" and the identified identity information, such as "crew 000001", can be displayed.
[0046] In some embodiments, the touch screen of the human-computer interaction unit 103 can also display the test results and test progress of the test control unit 102. Exemplarily, when the test control unit 102 is executing the test process, its test progress is "testing", then the test progress of the single tube can be displayed on the touch screen as "testing". In one embodiment, multiple test items can also be numbered, and the completion progress of multiple test items can be monitored, and the completion progress of multiple test items can be displayed in the test progress. Exemplarily, when there are 5 test items, 3 test items have been completed, then the test item completion progress can be displayed in the test progress as "3 / 5", or the test progress of multiple test items can be displayed in the form of percentage. After the test control unit 102 completes multiple test items and collects test data of multiple test items, the test data of multiple test items are displayed on the touch screen.
[0047] In some embodiments, they are connected to the unit identification unit 101 and the test control unit 102 respectively to store the test results. Figure 3 As shown, the data storage unit 104 may include a FLASH chip. In one embodiment, after completing the test on the air-conditioning unit and obtaining the test result, the test control unit 102 may store the test result in the data storage unit 104 .
[0048] In some embodiments, the data storage unit (specifically, a FLASH chip) can transmit the test data stored in the data storage unit to an externally connected central device through a USB interface, wherein the central device can summarize the test results of multiple air conditioning unit test devices and perform unified processing.
[0049] In some embodiments, the power supply unit 105 is used to provide power to the air conditioning unit test equipment. Figure 2 As shown, the power supply unit 105 may include:
[0050] Battery;
[0051] A charging management chip, used to monitor the charging and discharging of the battery based on the voltage information and current information of the battery; and
[0052] Voltage regulator chip, used to control the current of the battery output preset voltage.
[0053] In some embodiments, the battery may be a lithium battery. In other embodiments, the battery may be other types of batteries. The present application does not limit the battery type.
[0054] In some embodiments, the voltage stabilizing chip can control the battery to output a current of a preset voltage based on preset requirements, and the preset voltage can be customized based on user requirements.
[0055] In some embodiments, the power supply unit is also used to feed back the battery power information to the test control unit. When the test control unit determines based on the power information that the battery power is lower than a preset power value, a low power alarm is issued. When a low power alarm occurs and the test is currently in progress, the user can perform temporary emergency charging of the battery through the USB interface, for example, using a portable power source to charge the battery.
[0056] Figure 4 A schematic diagram of the structure of an air conditioning unit test system provided in one embodiment of the present application.
[0057] Reference Figure 4 As shown, the system may include a central device 10 and one or more air conditioning unit test devices 20. The air conditioning unit test device 20 may be Figure 1 or Figure 3 The central device 10 is connected to the air conditioning unit test device, and is used to collect and receive the test results of one or more air conditioning unit test devices, and when the test results contain equipment abnormality information, generate alarm information to alarm the equipment abnormality. Exemplarily, the central device 10 can be a PC device for staff to manage the test data of the air conditioning unit equipment.
[0058] In some application scenarios, such as in a large or super-large data center room, multiple server devices are installed, and the server devices can be cooled by the air conditioning wind wall unit. To ensure the stability of the air conditioning wind wall unit, the air conditioning unit can be tested regularly or irregularly, and abnormal units or faulty units can be repaired in time to ensure the effectiveness and stability of the air conditioning unit operation. During the test process, in order to improve the test efficiency, multiple air conditioning unit test devices can be used to test multiple server devices in parallel. After completing the test of a server device, the test result can be sent to the central device 10 for unified storage after the corresponding test result is obtained.
[0059] In some embodiments, the multiple test items may include safety test, analog input and output test, switch input and output test and communication status test of the air-conditioning unit. After determining the abnormal unit or faulty unit equipment according to the test results, the unit to be repaired can be quickly determined based on the identity information of the corresponding air-conditioning unit in the test results, and by sending a fault alarm, the maintenance personnel are prompted to go to the location of the unit to be repaired to troubleshoot the fault. In some embodiments, after the maintenance personnel complete the troubleshooting, they can also test again through the air-conditioning unit test equipment to ensure the operational stability of the air-conditioning unit.
[0060] In some embodiments, the safety test may include leakage current test, electrical strength test, insulation resistance test, and ground resistance test. In other embodiments, the safety test may also include other types of tests, and the present application does not limit the number of test items and the types of test items of the safety test.
