Description

Programmable multiplexing IO module test board

Technical Field

The utility model relates to an information programming technical field specifically is a multiplexing IO module testboard able to programme.

Background

Some projects need to test all IO interfaces when producing the programmable and reusable IO module, the existing test method is to embed a test program in the IO module, a tester tests according to the running steps of the test program, for part of IO functions, a test instrument and a signal generator are needed to be used for assistance, the test method needs to spend more time in the test operation process besides extra programming design time of the IO module, if a user program of the IO module is directly run, the IO module is tested by utilizing a computer monitoring program, for the IO interfaces, the test instrument and the signal generator need to be used for testing one by one, and more test time still needs to be spent, which is not beneficial to use.

SUMMERY OF THE UTILITY MODEL

This section is for the purpose of summarizing some aspects of embodiments of the invention and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract of the specification and the title of the application to avoid obscuring the purpose of this section, the abstract of the specification and the title of the application, and such simplifications or omissions are not intended to limit the scope of the invention.

In view of the above and/or the problems existing in the existing IO module test equipment, the present invention is proposed.

Therefore, the utility model aims at providing a multiplexing IO module testboard able to programme can effectual simplification test procedure, shortens test time, improves efficiency of software testing, but also direct operation IO module application when the test need not to imbed test program in the IO module, facilitates the use.

For solving the technical problem, according to the utility model discloses an aspect, the utility model provides a following technical scheme:

a programmable multiplexing IO module test bench is composed of a computer end, an interface board and a workbench, wherein the interface board comprises a multiplexing IO group 1 terminal, a multiplexing IO group 2 terminal, a temperature input terminal, a relay output terminal and a switching value input terminal, a standard resistor is installed on the temperature input terminal, and the computer end and the interface board are installed on the workbench.

Compared with the prior art: the prior method for testing the IO module is to embed a test program in the IO module, a tester tests according to the operation steps of the test program, and for partial IO functions, the test method needs to be assisted by a test instrument and a signal generator, the test operation process needs to spend much time except programming design working hours of the IO module, if a user program of the IO module is directly operated, the IO module is tested by using a computer monitoring program, for the IO interfaces, the test instrument and the signal generator need to be used for testing one by one, and much test time still needs to be spent, which is not beneficial to use, in the application document, the time wasted by detecting a plurality of test instruments in the prior art is reduced by adopting a method that an interface board and a computer end are embedded and installed on a workbench, and simultaneously, the application program of the IO module can be directly operated during testing, and a test program is not required to be embedded in the IO module, so that the operation is convenient, and the test time is reduced.
