Detailed Description
The invention is further described below. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The invention provides a single board testing system based on python, which has a specific structure shown in figure 1: the test system comprises a test host and a tester, wherein the test host is connected to a tester backboard through a USB interface.
Various test board cards are arranged on the tester back plate and comprise an input board card, an output board card, a power supply board card, an analog quantity test board card and the like, all the test board cards are connected through a CAN bus, and the CAN address is guaranteed to be flexibly configurable. The CAN bus has the characteristics of high speed and flexibility and configurability, and all the devices hung on the CAN bus CAN be flexibly increased and decreased. For the CAN bus address, a manual configuration scheme is provided, and the configuration mode of each slot resistance is adjusted in a welding resistance mode, so that the expandability is improved.
The continuously updated market demand can lead the test content to be gradually complicated, the flexible configuration of the address is reserved, the continuously updated capability of the tester is improved, any new standard board card for testing can be randomly replaced in the reserved slot position, and the integral compatibility capability is enhanced.
Various testing standard source interfaces including CAN port, serial port and 485 port are configured on the tester backboard, and various testing standard sources are connected to the tester backboard through corresponding interfaces to control input and output of various standard sources.
For a common test board card, the test content of the common test board card generally needs external voltage and current or a small signal source and the like to provide an original test environment, different test content generally needs different external sources, in order to ensure the compatibility of a debugging instrument, a tester backboard forwards related serial port content based on an FPGA, 4-6 com ports are configured on the tester backboard to be used for expanding related serial ports, and the common test requirements are basically met. And meanwhile, a strong current output interface is arranged on the back plate of the tester.
The test host computer adopts python language to complete the development process of the test program, and the specific contents are as follows:
the test host application layer comprises abundant network setting tools, all test hosts are connected to an enterprise intranet by using the extensible type of the test hosts in the same enterprise, all test reports and test contents can be shared and transmitted in the intranet, the test hosts upload the test reports through the intranet, and the test hosts compile and generate the test reports in a standard format based on python language.
The USB interface realizes the communication between the tester and the test host, the high-speed USB interface expands the tester to use the CAN port, the serial port and the backboard bus interface, the USB interface has the characteristics of hot plug and high speed, and the expansion tester is configured with various test standard source interfaces by utilizing the characteristics of the USB interface, thereby realizing the connection of the tester into various standard sources and improving the expandability of the tester.
The test host provides a standardized program interface for common test contents, such as common switching value test, analog quantity test, more uniform test method and more fixed test hardware, the test host software writes a standard test message based on python language, and the standard test message and a corresponding test function are packaged. For example, for the test of a common relay outlet board card, a uniform standardized program interface is formed, and the test can be completed by directly calling a test function during the test. In the testing process, the problem analysis is carried out by directly inquiring related variables in the testing host for related problems in the testing process by using the glue characteristic of python. For example, a pressure test is required for a part of test boards, a pressure test program is written in the test host, fault content is analyzed through recorded log content, a test report is generated, and the test content and the test report are stored in the test host.
For the test board cards using different main control chips, a common chip manufacturer finishes a drive program for using a test host to download the MCU program, the test host and the tester adopt USB for communication, and a debugging instrument can directly use the glue characteristic of python language to directly call the flash programming program of a chip manufacturer, thereby avoiding independent development of various download protocols.
The test system of the invention completes the development process of the test program on the upper layer of the test host by using the python language, the lower layer board level system only needs to provide a simple interface loop and a function test loop, the development process is independently completed by a tester, and the bottom layer driver completely uses an open source driver, thereby avoiding the development process of protocol content.
