In fig. 2, the top layer is a test service logic interface, which represents the specific service logic of the top layer of the test equipment; underlying the model are drivers of various test instruments and boards included in the test equipment, which may include standard drivers provided by instrument vendors, nonstandard driven API functions, package components thereof, and the like.

2. Collections of item-specific driven interfaces
In this embodiment, the test functions can be classified by the test equipment (especially, serialized test equipment), and a standardized drive interface is established for each test function and is collected together to form a standardized specific drive interface set for the equipment. The function realizing component of the test equipment comprises the incidence relation between each specific item driving interface and the test instrument or the board card
For example, for a series of test devices for detecting functions and performance of electronic products, although there are differences among the devices, the test devices are basically the same or similar only in terms of the functions to be implemented, so that the overall situation of the test items can be obtained through the aggregate analysis of the test functions, and the interface set of the device can be abstracted.

3) Realization component of test equipment driver (namely test equipment function realization component)
The implementation component of the test device driver is a specific implementation of the driver interface, and the implementation manner of the driver interface can be hardware or software. . The external interface of the test equipment driver provides a uniform operation port for upper application software, but the execution of the driver software of the test equipment must be established on the actual test equipment hardware, and each driver component represents a specific test instrument or board card, which contains the association relationship between each specific item driver interface and the test instrument or board card and can describe how the test instrument or board card realizes various specified functional items. The functional implementation of the test equipment depends on the integrated test instrument, board card and electrical connection topological relation.
The test device driver in this embodiment is implemented by 3 technical means, such as an external interface of the test device driver, a drive interface design for a specific function, and a driver implementation for a specific test device, and is specifically described as follows:
1. design of external interface of driver of test equipment
Referring to fig. 3, the external interface of the test device driver may be used to implement:
a. management of project-specific driven interfaces
First, the creation and integration of various driver-specific interfaces is completed. In the driver, an independent driver interface list may also be provided, and various test function items contained in the test device driver are managed in a centralized manner to describe all test capabilities of the test device (i.e. to generate a list of all test operations that the test device can perform).
Secondly, a specific driven retrieval function can also be provided. The test device driver includes various specific drive interfaces inside the driver in a combined manner, and the specific drive interfaces are invisible to the outside, so that an external retrieval function needs to be provided, and the searched specific drive interfaces are provided for an upper-layer test program.
b. Management of test instruments and boards
The system is responsible for managing various test instruments and board cards in the test equipment, the realized operation comprises the opening, resetting, closing, checking and the like of the various test instruments and board cards, and the resources of the test instruments and board cards are uniformly integrated in a list. The external interface is only responsible for basic operation of a hardware instrument and does not relate to specific test functions.
2. Specific function-oriented project-specific driven interface design
Firstly, aiming at each test function obtained in the functional decomposition of the test system, an independent specific function item driving interface is established, and a standard interface definition is provided, which represents an independent test function required to be realized by the test equipment.
Taking electronic product testing equipment as an example, although the hardware configurations of the testing equipment are different, the overall demand situation of the testing equipment can be summarized from a higher level. The hardware requirements CAN be divided into several categories, such as direct-current power supply control, serial port communication, analog quantity control, digital quantity control, pulse signal output, fiber-optic gyroscope integration test, PWM signal acquisition, VF constant-current source output, counter signal control, network communication, CAN communication, 1553B bus communication and the like. The specific project driving interface can be flexibly selected according to the actual test requirement.
Secondly, the design of the driving interface corresponding to each test function is completed. Each specific drive interface represents an independent test function item, and the content of difference among different functions is reflected. When the upper layer test service logic is developed, various specific service processes are essentially completed through instantiation objects of a specific drive interface.
3) Driver implementation for specific test equipment
The driver interface of the test equipment is directly realized aiming at the driver of the specific test equipment, and the specific realization can be divided into two parts, namely the realization of the basic function which is defined in the driver model and has the public property; secondly, the test equipment is realized with various specific driving interfaces.
a. Implementation of basic functions
The project-specific driven interface may be created as follows:
when implementing a specific project driven interface, the function of the specific project driven interface core is to implement instantiation of various functional project driven interfaces and assemble them in a "driven interface list". The pseudo code for this function is as follows:
b. initializing a test instrument and a board card:
after the initialization of the hardware of the test instruments and the board card is finished, the hardware can be stored in a test equipment driver in different types to serve as the development basis of various subsequent functional projects.
c. Implementation of a specific drive interface
For each item of content in the driver interface list (i.e. each test operation that the test equipment can perform), it needs to be implemented one by one when the driver component is developed; each functional item is ultimately implemented on a hardware instrument so that the driver components are closely coupled to the automatic test equipment. In the driver component, various heterogeneous drivers are called to realize the design requirements of the test equipment, so that various externally provided virtual test items are converted into real test functions.
The development steps of the test function project can be as follows:
step 1: and establishing an implementation class corresponding to the function item driving interface.
Each test function item is in a local and global relationship with the device driver. The implementation class of the specific drive function directly corresponds to each interface in the specific drive interface set, different interfaces complete specific test functions through different implementation classes, and the implementation classes generally exist in the form of internal nested classes and are uniformly contained in the implementation components of the driver.
Step 2: and (5) concrete implementation of functional items.
For non-standard instruments, API functions provided by hardware manufacturers are used, or a packaging library is formed through secondary development; for standard instruments, class IVI drivers or dedicated driver components may be invoked directly. After the driver component is developed and debugged, the component is not modified unless the hardware is changed.
Step 3: implementation of functions
The functional items are oriented to test the system level functions of the equipment, and are not only simple operations on instruments. Taking analog quantity acquisition as an example, when a digital multimeter is used, a measured value is processed by an instrument and can be directly read; however, when the PCI card is used, it is necessary to perform necessary signal processing (such as smoothing and field point removal) on a plurality of sets of continuous values acquired at a high speed to obtain more accurate data.
When creating a test device driver, the present embodiment first designs a model of the test device driver. The core of the model is that a separate test device driver is added between the service logic and a specific instrument driver, and the direct connection between the upper layer and the lower layer is isolated through the separate test device driver, so that all operations related to hardware are encapsulated. The test service logic program is developed only for the test equipment driving interface.
Secondly, an external interface of the driver of the test equipment is designed, the external interface is a unique port provided externally, and the specific implementation of the interior of the driver is shielded. The external interface of the driver can be applied to development of test software of different types and models, in other words, for upper-layer application software, differences caused by differences of hardware equipment and instruments can be ignored, so that application developers can concentrate the working gravity on business logic per se, and requirements and changes of the upper-layer software can be met more conveniently and flexibly.
Followed by the interface design for the specific test function. Through the analysis of the functions required to be realized by the specific class of test equipment, a function item set separated from a hardware environment is obtained, and a standardized equipment driving interface is established. Each specific test function driving interface represents an independent test function item, and a plurality of driving interfaces are organized together to form a virtualized test device with various hardware test functions of the test device.
Finally, the implementation of the driver for a specific test equipment. The driver implementation component corresponding to the hardware is developed for specific test equipment hardware, and the control of a hardware instrument is packaged in the driver implementation component, so that the function implementation of actual test equipment is described. The test equipment driver provides a uniform development and operation basis for upper-layer software, and the test program develops aiming at the virtualized functional interfaces, so that the influence of the difference of hardware on service logic is avoided.
Of course, it is understood that other variations of the above detailed flow can be made, and all such variations are intended to fall within the scope of the present invention.
In the embodiment of the invention, the external interface is used for selecting a specific item driving interface matched with a test item from a plurality of specific item driving interfaces integrated by the external interface according to the test item received from the test service logic interface; the test service logic interface is used for transmitting test programs of different test items; the test equipment function realization component is connected with a plurality of test instruments or drive programs of the board cards; the function realization component of the test equipment comprises an incidence relation between each specific project driving interface and a test instrument or a board card; the test equipment function realization component is used for calling a plurality of test instruments or board cards related to a specific item drive interface selected by the external interface to execute test operation according to the correlation relation, so that the specific item drive interface matched with the test item can be selected through the external interface, and further the test equipment function realization component is used for calling a plurality of test instruments or board cards to execute the test operation, so as to realize execution of different test items; meanwhile, different test instruments or board cards can be uniformly driven; further, the test instrument or the board card after hardware upgrading and modification can still be driven; the driver development of each test instrument or board is not needed, so that manpower and materials are saved, the reusability is improved, and the repeated development is avoided.
As described above, embodiments of the present invention are directed to a method for designing a driver for a dedicated test device. The driver is a group of software functional units which aim at controlling the test equipment, is used as a bridge for communicating a bottom hardware driver with upper test software, provides a uniform software and hardware interface for upper software development, and standardizes the implementation mode in the driver. The test equipment driver realizes the separation between the top business logic and the bottom driver and provides a standard external port of a hardware layer.
The test equipment driver aims at the fact that the equipment needs to realize system level test functions and is not different in various instruments or board cards. Second, the external interface of the test device driver is the only port provided externally. In the interior of the test device, a plurality of test function item interfaces are included in a list mode, which indicates that the automatic test device has a plurality of different independent test functions and can be expanded at any time according to the development condition of the device, but the external description of the test device is not influenced. The interface design of a specific test function describes the specific details of a certain functional item, represents a completely abstract, system-level function, and is independent of hardware (including test instruments, boards, test equipment, etc.), and thus is more general. A plurality of driving interfaces are organized together to form a virtualized testing device, and various hardware testing functions of the testing device are achieved. Separate driver components are developed for a particular test device. Aiming at each automatic test device, a virtual device driver component is provided to shield the difference of bottom hardware drive and the difference of hardware electrical design, and various functions of the device are integrated inside the device to be used as the running basis of upper application software, and the device can be globally reused after the development is finished.
