Embodiment Construction

[0029] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] Such as Figure 1 to Figure 3 As shown, there are three forms of switching output of the device under test, and the switching output signal is provided to the outside through the switch control closure.figure 1 Shown is the first form of switch output of the device under test. This form is to control the on-off of the positive pole of the 24V / 28V DC power supply to realize the output of the switch signal. The device under test includes a switch S1 and a 24V / 28V DC power supply, the switch S1 is connected to the output of the positive pole of the 24V / 28V DC power supply in the circuit, the other end of the switch is connected to the output terminal 1, and the negative pole of the 24V / 28V DC power supply is directly...

Abstract

The invention relates to a multipurpose switching value detection device, and belongs to the field of testing. The invention provides a multipurpose switching value output detection device which can detect switching value output of detected equipment in three forms. The invention also provides a multipurpose switching value input detection device, which can detect the switching value input of the detected equipment in three forms. The switching value detection device can be controlled in a program-controlled manner and can be obtained and controlled through software; the number of the switching value input and output channels can be set according to the maximum number of the channels of the tested equipment or the switching value channels of the tested equipment can be tested in the forms of superposition and the like; the switching value input and switching value output in the switching value detection device are in form generalization, and the purpose of simplifying test tool management and realizing form generalization is achieved.

Description

technical field [0001] The invention belongs to the field of testing, and in particular relates to a multi-purpose switching value detection device, in particular to a switching value input and output detection method which is used in one port. Background technique [0002] The switch input and output detection device is an indispensable detection device in the field of industrial control. The commonly used detection method is to detect a certain type of switch signal, such as fixed output and fixed input. Contacts are for input and contacts are for output. Since there are many types of switching signals to be tested, there are also many detection devices. One type of detection device corresponds to one type of switch signal test, and the test is cumbersome in the detection of multiple types of switch value signals. At the same time, the management, maintenance and calibration of the detection device in the later stage will add part of the work. Aiming at this phenomenon, ...
