By way of example, and not limitation, when the terminal device is a computer. The computer is not only a hardware device, but also realizes a powerful function through software support and data interaction and cloud interaction.

As an example, but not limited to, taking the terminal device as a computer example, taking the detection operation as an example of a calibration test operation, please refer to fig. 1, fig. 1 is an application scenario diagram of a product detection method provided by an embodiment of the present application, which is described in detail below:

The terminal equipment is connected with the PLC module through the PLC bus, and the terminal equipment establishes communication with the upper computer.

Connecting a process calibrator with a communication interface to a computer, connecting an expansion module needing auxiliary production work with a module to be tested, and configuring the expansion module to a PLC module of the company;

The PLC module is communicated with the computer through the Ethernet; writing a calibration test program through a computer; and the computer and the upper computer control the operation of a calibration test program in the PLC module, and meanwhile, the returned data can be utilized to check the calibration test progress, the returned parameters and the module state information. The module status information includes success or failure information.

By way of example, and not limitation, taking a PLC module as an example of the UN smart series product, examples are as follows:

(1) The simplified flow: after the upper computer software of the computer starts to run the calibration test program, the process calibrator with the communication interface is controlled, and the process calibrator is communicated to the PLC through the Ethernet, a set of control logic written by utilizing the special library file used by the invention is run in the PLC, and the PLC module and the expansion module are connected in a normal configuration mode. The expansion module comprises a finished product module which passes the calibration test and a module to be tested which does not pass the calibration test. Taking a module to be tested as an analog product for example, the analog product comprises an input module and an output module, and the modules are respectively used for detecting voltage and current, various sensor signals and the like.

(2) Calibration input: if only the input signal is calibrated, we can simplify the flow according to the above (1), and the expansion module only needs one input module to be tested, and the other connections are unchanged. After the ladder diagram program is written, the relay terminal of the PLC module is connected in series between the output port of the process calibrator and the input port of the input module. The upper computer is used for opening a calibration function, the upper computer sends a calibration command to the PLC module through the Ethernet, and the PLC module forwards the command to an input module to be tested after receiving the calibration command; and after receiving the input module to be tested, executing a corresponding calibration function, and finishing the feedback completion mark, wherein the PLC also assists in switching the relay according to different commands. The calibration input is relatively simple, an input module with input calibration completed is obtained, and other output modules can be padded.

(3) Calibration output: after knowing the method of (2) calibration input, calibrating output; the input module after calibration in (2) and the output module to be tested can be configured together. Connecting the output terminal to be calibrated to the input terminal of the calibrated input module; the input precision and consistency of the calibrated input module are quite high, and the input precision and consistency of the calibrated input module are far higher than the output precision requirement of the output module; therefore, after the physical connection is completed, a corresponding calibration program is used, the value of the output module is read through the input module, and is fed back to the output module through the bus, so that the output module is calibrated.

(4) Calibration input/output: the same applies to modules with both inputs and outputs; only the requirements of (2) and (3) are needed to be combined; the actual physical connection of this calibration mode is shown in fig. 1. Different from the step (2), the process calibrator is connected in series through a relay of the PLC and then is connected to an input terminal of a module to be tested; the input module used as the calibration aid is responsible for calibrating the output terminal of the module to be tested. Thus, a module with input and output functions can be completed.

(5) And (3) testing: after calibration, the PLC program is also provided with a test program, and the test function is realized by additionally installing an input module and an output module with additional accuracy and consistency and matching with an I/O output module with a relay. After the test program in the PLC runs automatically; the module to be tested is controlled to switch different functions, the I/O output module with the relay is controlled to switch signals to different input modules and output modules for auxiliary test, and the PLC is matched with the input modules and the output modules for auxiliary test to complete the test function.

(6) After-sales testing: after-sales products can also detect problems through the calibration test jig made by the logic, and factory information of some factories, such as version numbers, can be read; is convenient for anti-counterfeiting and version control.

(7) Others: the front process check meter can also be controlled by a serial port of the PLC, the process check meter in the example is controlled by a computer or an upper computer, the two are not in conflict, and the upper computer is used only for controlling more conveniently and more visually; similarly, the whole process can be realized by adopting a PLC ladder diagram and a calibrator. In addition, the output is equally feasible if it is desired to use a process calibrator to perform calibration tests with greater accuracy. The degrees of freedom are quite high and the solutions presented here are only illustrative.

In the embodiment of the application, the calibration step can be completed by connecting the standard product module, the PLC, the module to be tested, the process calibrator and the like which are subjected to the calibration test together and matching the connection structure, so that the calibration test process in the production process is simplified.
