Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of testing, in particular to an air conditioner controller function testing method, a testing system, an air conditioner controller and a testing device. BACKGROUND

[0002] An air conditioner controller product usually includes a hardware part and a software part. The hardware part includes electronic elements, circuit boards, sensors, actuators, etc., and is the basis for realizing electric control functions. The software part includes control algorithms, drivers, user interfaces, etc., and is responsible for converting hardware resources into available control functions.

[0003] The software burned and solidified in the electric control product (air conditioner controller) is called an embedded program. Before product development and shipment, testers not only need to detect the functions of the hardware part of the product, but also need to test the functions of the embedded program to ensure the availability of the program. The test of the embedded program usually includes hardware function testing and application function testing. The hardware function testing mainly tests the physical index detection capability and hardware execution capability of the hardware, so as to reflect whether the physical components and circuits in the air conditioner controller realize the related functions; the application function testing mainly tests the internal logic of the embedded program and the control and processing method of the hardware. If manual testing is adopted, the experience and testing level of the tester are highly dependent, and the labor cost is high. Automatic testing speeds up the testing period and reduces the testing and labor costs, so it is an inevitable trend to replace manual testing with automatic testing.

[0004] To the best of the inventors' knowledge, most existing automatic tests can only be applied to pure software, and fewer can be applied to embedded program testing. The automatic test management software developed by Labview is currently known on the market for embedded program automatic testing, which needs a matching board for carrying the Labview test program. Because the test program and the matching board are provided by Labview company, a specific protocol is needed to realize the communication between the matching board and the device under test. Because the matching board is widely used in commercial applications, it has comprehensive integrated functions, and the cost of purchase is also high. In addition, the application cost of Labview software itself is also very high.

[0005] Moreover, the automatic test process of the embedded program by Labview includes: calling test cases through the matching board, using the output signals of the test cases as the output signals of the matching board and inputting the output signals into the input signals of the device under test. The device under test performs corresponding operation functions and outputs corresponding electrical signals after receiving the input signals. The matching board detects the electrical signals through the detection circuit to determine whether the electrical signals meet the expectations. In the whole test process, when the hardware of the device under test is tested, the input signals are processed by the device under test and the corresponding operation functions are performed before detection. Therefore, the coupling degree of the program is high, and the test process and test results are easily affected. SUMMARY

[0006] Therefore, the application provides an air conditioner controller function test method, a test system and related equipment to solve the problems of high cost of matching boards and test software of the test method, and high coupling degree of the function test program, which affects the test process and test results.

[0029] The following technical solutions provided by the present application will be described in combination with the drawings in the present application.

[0030] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting to the present application. The terms "first", "second" in the technical solutions of the present application are only for the purpose of description and cannot be understood as indicating or implying relative importance, operation time sequence or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more of the features.

[0031] In order to facilitate the understanding of the technical solutions of the present application, first of all, some technical terms related to the present application are introduced.

[0032] Electric control products refer to devices and systems that control hardware systems through electronic or electrical equipment, and are widely used in many fields such as automobiles, industries, homes, robots, power, medical treatment, etc.

[0033] Electric control products usually use a combination of software and hardware to achieve efficient, reliable and intelligent control. For example, joint design, collaborative optimization of software and hardware, software and hardware development based on models or embedded systems, and hardware acceleration based on Application-Specific Integrated Circuit (ASIC) or Field Programmable Gate Array (FPGA) can be performed. The present application takes air conditioner controller as an example to illustrate that air conditioner controller products usually include hardware part and software part. The hardware part includes electronic components, circuit boards, sensors, actuators, etc., which is the basis for realizing electric control function. The software part includes control algorithm, driver program, user interface, etc., which is responsible for converting hardware resources into available control functions.

[0034] When developing the software of air conditioner controller, testers often need to test the developed embedded program (hereinafter referred to as program) to ensure the usability of the program. The test of embedded program usually includes hardware function test and application function test, wherein the hardware function test mainly tests physical indicators, such as temperature, voltage, current, etc., to reflect whether the physical components and circuits in the tested electric control product realize the related functions; the application function test mainly tests the internal logic of the embedded program, such as the conditions when the circuit realizes the function, etc.

[0035] However, the related test method often needs to test the hardware function and application function of air conditioner controller at the same time, not only needs to meet the hardware function and application function conditions at the same time during testing, but also the output mode has multiple combinations. This method needs to provide an interface through the test main board to connect with the tested hardware, and based on the test main board to detect the output of the tested product, so as to judge the function of the tested product through the output, therefore the interface resources required by the output mode of different combinations of application function and hardware function of different electric control products are different in type and quantity, so multiple test main boards are needed to assist the test, and the hardware cost is high.

[0036] In view of this, the application provides an air conditioner controller function test method. The method is applied to a test system. The test system includes a test device and an air conditioner controller. The test device can perform function test on a program of the air conditioner controller. The embedded program includes an application function layer and an interface layer. The test device is in communication connection with the electric control product under test. As an example, the communication interface can adopt, for example, a serial communication interface or a network port or a USB, etc. The test device is installed with test software. The test software includes a simulation hardware module. The method includes application function layer test.

[0037] The simulation hardware module sends first test input information to the application function layer through the interface layer. The first test input information and corresponding first predicted output information are obtained from the test device. The application function layer generates first test output information and returns the first test output information to the simulation hardware module through the interface layer. Then, the test device can perform application function test on the program according to the first test output information.

[0038] The embodiment of the application realizes separate test on the application function layer. On the one hand, the application function test and the hardware function test are decoupled. There is no need to test the multiple output combinations of the application function and the hardware function. Thus, the required interface resource types and quantity are reduced. The demand for the test main control board for auxiliary test is reduced. The hardware cost is reduced. On the other hand, the application function test and the hardware function test are decoupled. The test limitation is reduced. The test time is shortened. Thus, the test efficiency is improved. The development efficiency is improved. Next, the air conditioner controller function test method provided by the embodiment of the application will be introduced in combination with the drawings.

[0039] Referring to Figure 1 A flowchart of an air conditioner controller function test method disclosed by the embodiment of the application is shown. The method is applied to a test system. The test system includes an air conditioner controller and a test device. The test device can perform function test on an embedded program of the air conditioner controller.

[0040] The embedded program of the air conditioner controller includes an application function layer and a hardware function layer. The application function layer is used to realize multiple application functions of the air conditioner controller. The hardware function layer is used to realize multiple hardware functions of the air conditioner controller. The test device is installed with test software. The test software includes a simulation hardware module and a simulation application module. The test device is in communication connection with the air conditioner controller. As an example, the communication interface can adopt, for example, a serial communication interface or a network port or a USB, etc. to connect with the test device.

[0041] Figure 1 The method includes the following steps:

[0042] S102: The simulation hardware module sends first test input information to the application function layer through the interface layer.

[0043] The simulation hardware module in the test device is a simulation hardware module generated by the test device based on the embedded program of the electric control product under test, the protocol between the application function layer and the hardware function layer. The simulation hardware module is used to replace the actual hardware function layer in the application function test, so as to test the function of the application function layer of the embedded program.

[0044] The first test input information used for the application function layer test can be pre-stored in the test device. The corresponding first predicted output information can be pre-stored in the test device, or can be obtained by inputting the first test input information into the test case.

[0045] In some possible implementations, the test device can use a test case to automatically send the first test input information, such as control information, from the simulation hardware module to the application function layer through the interface layer. In this way, the test device can automatically test the application function layer of the program according to the test case, improve the coverage of the test, and improve the test speed. In addition, the automatic test can also reduce the operation difficulty caused by the test condition in manual test, and free the related technical personnel from the tedious test process.S104: The application function layer generates the first test output information and returns the first test output information to the test device (which can be the simulation hardware module or a storage address other than the test software on the test device) through the interface layer.

[0046] After the application function layer in the program of the air conditioner controller receives the first test input information sent by the simulation hardware module in the test system through the interface layer, the first test output information can be obtained in response, and the information is returned to the simulation hardware module through the interface layer. The first test output information can include related code in the application function layer, and the working state of the circuit module controlled by the code after running in response to the first test input information. For example, the first test input information indicates turning on a light bulb, and the first test output information can return the switch state of the light bulb.

[0047] S106: The simulation hardware module performs application function test on the embedded program according to the first test output information and the corresponding first predicted output information.

[0048] The test device can determine whether the embedded program of the air conditioner controller performs the related operation corresponding to the first test input information through the returned first test output information, and further determine the availability of the application function layer. For example, the first test input information indicates turning on a light bulb, and when the switch state of the light bulb returned by the first test output information is on, it can be determined that the application function layer accurately performs the related operation.

[0049] In some possible implementation manners, the corresponding first predicted output information is included in the test case of the test device. In this way, the test device can automatically determine the result of the application function test according to the prediction result and the actually returned first test output information. For example, when the difference between the prediction result and the first test output information is less than a threshold value, it can be determined that the application function of the air conditioner controller product is normally operated.

[0050] In this way, the automatic test of the application function layer can be implemented, and the test efficiency is significantly improved.

[0051] The above steps are the process of the application function test on the application function layer of the embedded program. Referring to Figure 2 As shown in the schematic diagram of the function test method of the application function layer, the simulation hardware module in the test device replaces the hardware function layer in the program, and is configured to provide input information to the application function layer and receive the output information returned by the application function layer through the interface layer. Then, the test device can test the application function according to the returned output information.

[0052] In some possible implementation manners, the test system can also test the hardware function of the air conditioner controller. Specifically, the simulation application module in the test device can send second test input information to the hardware function layer through the interface layer. The hardware function layer can generate second test output information according to the second test input information, and send the second test output information to the input and output component connected to the air conditioner controller. In this way, the result of the hardware function test can be observed on the input and output component. Alternatively, the hardware function layer receives third input information sent by the input and output component, and generates third output information, and then sends the third test output information to the simulation application module through the interface layer, where the third output information can test the hardware function of the program.

[0053] Figure 3A As shown in the schematic diagram of the function test method of the hardware function layer.

[0054] The simulation application module in the test device is a virtual application module generated based on the protocol between the application function layer and the hardware function layer in the embedded program of the air conditioner controller, and can include the application logic code or the business logic code of the program. The simulation application module is configured to replace the actual application function layer in the hardware function test, so as to test the hardware function layer of the embedded program.

[0055] The input and output components are connected to the air conditioner controller, and are used to provide input information to the air conditioner controller or receive output information, so as to simulate the actual operation scene of the air conditioner controller, analyze the input and output information of the system, and test the function of the product. For example, the input and output components can include a keyboard, a touch screen, a mouse, a sensor, a signal generator, an oscilloscope, a logic analyzer, a display, a multimeter, and the like. In some possible implementations, the input and output components can also not be specific physical elements, but can be replaced by equivalent circuits or elements. The input and output components can be manually configured by a test personnel according to the air conditioner controller, or can be pre-deployed.

[0056] In some possible implementations, as shown in Figure 3A , the simulation application module can send second test input information to the hardware function layer through the interface layer. The hardware function layer in the embedded program of the air conditioner controller receives the second test input information sent by the simulation application module in the test device through the input and output components, can generate second test output information, and sends the second test output information to the input and output components connected to the air conditioner controller.

[0057] The second test output information can be physical index data returned by the hardware function layer, such as temperature, voltage, current, and the like, or can be a signal including the above index information. The input and output components can convert the second test output information returned by the hardware function layer into visual information, to facilitate a test personnel to more intuitively observe the test result. For example, when the input and output components are an oscilloscope, a display, or the like, the input and output components can acquire the second test output information, and display a waveform corresponding to the second test output information. In this way, the characteristics of the second test output information can be more intuitively displayed, to more comprehensively test and analyze the hardware function layer.

[0058] In some possible implementations, as shown in Figure 3B , the simulation application module can receive third output information sent by the hardware function layer through the interface layer, where the third output information is response information generated by the hardware function layer after receiving third input information sent by the input and output components, and is used to perform hardware function testing on the program.

[0059] In some possible implementation manners, the test device can perform hardware function testing on the program according to the reference value of the third test output information. Specifically, the reference value of the third test output information is determined according to the third test input information and the mapping relationship, where the mapping relationship depends on the hardware function layer of the embedded program. The test device can perform hardware function testing on the program according to the received third test output data and the reference value. For example, the test device can determine whether the hardware function of the embedded program meets the expectation according to whether the difference between the third test output data and the reference value exceeds a threshold. In this way, the hardware function can be systematically tested, and accidental errors can be reduced and the testing efficiency can be improved.

[0060] It should be noted that the reference value of the third test output information can be stored in the test device in advance, can be obtained according to the third test input information and the mapping relationship sent by the hardware function layer, or can be obtained by inputting the test device from other external information sources, and the embodiments of the present application do not limit how to obtain the reference value of the third test output information.

[0061] In some possible implementation manners, the input and output component can be controlled by the test device. As shown by the dashed line in Figure 3C , the simulation application module can send input information to the hardware function layer through the input and output component. In this way, the test process can be performed under the control of the test device, and the influence of external factors on the test result can be reduced.

[0062] In a possible implementation manner, as shown by the solid line in Figure 3C , the hardware function layer in the embedded program of the air conditioner controller can return the test output information to the simulation application module through the input and output component. In this way, the simulation application module can obtain the test output information of the hardware function layer in response to the test input information, and store the test output information, which is beneficial to save and call the test information and avoids repeated operations in the future.

[0063] It should be noted that the above two processes need to be implemented based on the specific input or output function of the input and output component.

[0064] Figure 2 and Figure 3A , Figure 3B , Figure 3C respectively show the processes of the test system in testing the application function and the hardware function of the air conditioner controller. It should be noted that the processes of the above two function tests are independent of each other. That is, the test system can perform hardware function testing alone, can perform application function testing alone, can perform hardware function testing first and then perform application function testing, or vice versa, and the embodiments of the present application do not limit this.

[0065] In some possible implementation manners, the test system can perform parallel testing on multiple test physical indexes in the hardware function layer, or the test system can perform parallel testing on different application functions in the application function layer in parallel. In this way, the test time can be shortened, and the test speed can be improved.

[0066] In some possible implementation manners, the test system can further present a start test option to the user through the display interface, and then perform function testing on the embedded program in response to the start test option triggered by the user. For example, the start test option can include a start hardware function test option and a start application function test option, so that the user can select a corresponding function test mode according to requirements.

[0067] Through the above description, the embodiment of the present application provides an air conditioner controller function test method. The method decouples hardware function testing and application function testing. On the one hand, the method does not need to test multiple output combinations of application functions and hardware functions, thereby reducing the types and quantities of required interface resources, reducing the demand for a test main control board for auxiliary testing, and reducing hardware costs. On the other hand, the method can reduce test restrictions and shorten test time, thereby improving test efficiency and further improving development efficiency. The above embodiment mainly describes the process of the air conditioner controller function test method in detail.

[0068] It is necessary to describe the generation of the interface layer. Specifically, the generation of the interface layer includes the following steps.

[0069] Referring to Figure 4 FIG. 1 shows a flowchart of a method for generating an interface layer. The method includes the following steps.

[0070] S402: The test software generates an interface layer generation template according to a protocol between the application function layer and the hardware function layer in the embedded program.

[0071] The protocol between the application function layer and the hardware function layer is used to define the data interaction relationship between the application function layer and the hardware function layer, for example, a driver layer protocol, a middleware layer protocol, and other communication protocols. The driver layer protocol can convert the data of the hardware function layer into a format that can be processed by the application function layer. The middleware layer includes an operating system and can communicate with the application function layer of the embedded program through a specific application programming interface (API). The other communication protocols include a standard universal asynchronous receiver / transmitter (UART), a serial peripheral interface (SPI), an Inter-Integrated Circuit (I2C), and a protocol customized for a specific application function layer.

[0072] The interface layer generation template is generated through the protocol between the application function layer and the hardware function layer in the embedded program, so that the template can realize data interaction with the application function layer and the hardware function layer, respectively. In this way, the interface layer generated based on the first code can directly interact with the application function layer and the hardware function layer, respectively, so as to separate the application function layer and the hardware function layer at the data interaction level. In addition, the interface layer generation template is generated based on the standard protocol between the application function layer and the hardware function layer in the embedded program, so that the interface layer generation template can be used for different types of embedded programs of electronic control products.

[0073] S404: The test software generates the interface layer according to the interface layer generation template and the circuit control object controlled by the program.

[0074] The embedded program of the air conditioner controller controls a plurality of circuit control objects to realize a plurality of functions of the air conditioner controller. For example, the circuit control objects can be different circuit elements or circuit modules for realizing a certain function. When testing the physical indicators in different functions of the embedded program, the target circuit control object that realizes the target function needs to be determined, test information needs to be input to the target circuit control object, and the feedback output information needs to be obtained. The interface layer generation template can be used to realize data interaction between the application function layer or the hardware function layer in the embedded program. However, the interface layer generation template does not define the correspondence between the data objects in the template or the protocol and the circuit control objects actually controlled by the program, so it cannot complete the information interaction with the specific circuit control object. Therefore, the interface layer generation template needs to be improved according to the correspondence between the data objects in the template or the protocol and the specific circuit control object, and the interface layer needs to be generated.

[0075] After the correspondence is acquired, the test software can store the correspondence in various ways, including a table, a set, a tree structure, a configuration file, etc., and the embodiments of the present application do not limit the specific storage form. For example, the test software can acquire the correspondence between the data objects in the interface layer generation template or the protocol and the circuit control objects actually controlled by the embedded program, and store the correspondence in a table, and then generate the interface layer based on the table and the interface layer generation template.

[0076] The interface types of the plurality of circuit control objects are not necessarily the same, and therefore the interface needs to be generated according to the required interface type of the circuit control object. Thus, the above-mentioned correspondence can include at least one of the address of the data object in the template or the protocol, the name of the circuit control object, and the circuit control object in the selected virtual port of the interface layer.

[0077] It should be noted that the above-mentioned correspondence can also be directly acquired and stored by the test software from the external environment, and the embodiments of the present application do not limit how the above-mentioned correspondence is obtained.

[0078] Through the above description, the embodiments of the present application provide a method for generating an interface layer, which can generate a corresponding interface layer for an embedded program based on the protocol between the application function layer and the hardware function layer of the embedded program, and the correspondence between the data objects in the protocol and the circuit control objects controlled by the embedded program, so that the application function layer and the hardware function layer respectively interact with the outside world through the interface layer, and the application function layer and the hardware function layer are separated at the data interaction level, thereby realizing the decoupling of hardware function testing and application function testing.

[0079] Next, from the perspective of the air conditioner controller, the functional test method provided by the present application is introduced.

[0080] The present application provides an air conditioner controller functional test method, which is applied to an air conditioner controller, the embedded program of the air conditioner controller including an application function layer, a hardware function layer and an interface layer, the application function layer and the hardware function layer being connected with the interface layer respectively, and the method comprising:

[0081] The application function layer receives first test input information through the interface layer, and then generates first test output information and sends the first test output information through the interface layer, the first test output information being capable of performing application function testing on the program.

[0082] In some possible implementation manners, the method further comprises:

[0083] The hardware function layer receives the second test input information through the interface layer, generates the second test output information, and sends the second test output information to the input and output component connected with the air conditioner controller, and the second test output information can perform the hardware function test on the embedded program.

[0084] Alternatively, the hardware function layer receives the third input information sent by the input and output component, generates the third output information, and then sends the third test output information through the interface layer, and the third output information can perform the hardware function test on the embedded program.

[0085] The application further provides a function test method applied to a test device, the test device is installed with test software, the test software includes a simulation hardware module, the test device is in communication connection with an air conditioner controller, and the method includes application function layer test:

[0087] The simulation hardware module receives the first test output information;

[0088] The simulation hardware module performs application function test on the embedded program by using the first test output information and the first predicted output information.

[0089] In some possible implementation manners, the test software further includes a simulation application module, and the method further includes hardware function layer test:

[0090] The simulation application module sends second test input information through the interface layer to perform the hardware function test on the embedded program, or the simulation application module receives third output information through the interface layer, and the third output information can perform the hardware function test on the embedded program.

[0099] generate an interface layer generation template according to the protocol between the application function layer and the hardware function layer in the embedded program, wherein the interface layer generation template is used to define the data interaction relationship between the application function layer and the hardware function layer; and generate the interface layer according to the interface layer generation template and the circuit control object controlled by the program.

[0100] In some possible implementation manners, when the interface layer is generated according to the interface layer generation template and the circuit control object controlled by the program, the generation module is specifically configured to:

[0101] obtain the correspondence between the data object in the interface layer generation template and the circuit control object controlled by the program, and then generate the interface layer according to the interface layer generation template and the correspondence.

[0102] The correspondence can include at least one of an address of the data object, a name of the circuit control object, and a selected virtual port of the circuit control object in the interface layer.

[0103] In some possible implementation manners, the test device can further include a user interaction module configured to present a start test option to a user through a display interface, so that the test system can perform the function test on the program in response to the start test option triggered by the user.

[0104] In the above embodiment, the application function layer test and the hardware function layer test are not limited in sequence.

[0105] In the technical solution, the air conditioner controller can be a master controller, a frequency converter, a line controller or the like. The test device can be a computer, an IPAD or a mobile phone or the like.

[0106] In the above technical solution, the software, hardware, firmware or any combination thereof can be used to realize the technical solution in whole or in part. When the software is used, the computer program product can be used to realize the technical solution in whole or in part.

[0107] If each air conditioner controller to be tested has a unique identification code, the physical port can be divided into sub-ports to realize the simultaneous test of multiple air conditioner controllers.
