Problems solved by technology

[0002] The present invention introduces a universal interface adapter suitable for various types. In the past, due to the different signal types and electrical interface modes of each type of product, the corresponding comprehensive test equipment was equipped with a type of special interface adapter, without considering the universality requirements of the adapter. Therefore, the test equipment for each type of product can only test one product, and the comprehensive test resources are not used, which will inevitably lead to an increase in the number of comprehensive test equipment and equipment costs, which is not conducive to the reduction of equipment costs and the improvement of economic benefits

Abstract

The invention relates to a universal interface adapter which comprises a conditioning circuit, an isolation circuit, a voltage dividing circuit, an operational amplifier circuit and a test interface. The test interface includes an analog output interface, a digital input / output interface and an analog input interface. The analog input interface has multiple channels. The digital input / output interface has multiple channels. The universal interface adapter improves the utilization rate of comprehensive test resources, and can be used as a common test platform of two types of products to meet the functions of testing two types of products, saving costs for companies, having considerable economic benefits for the development of models. This design method makes it easier to develop interface adapter to meet the development demand of a company.

Description

technical field [0001] The invention belongs to the field of general interface adapters, in particular to a general interface adapter Background technique [0002] The present invention introduces a universal interface adapter suitable for various types. In the past, due to the different signal types and electrical interface modes of each type of product, the corresponding comprehensive test equipment was equipped with a type of special interface adapter, without considering the universality requirements of the adapter. Therefore, the test equipment for each type of product can only test one product, and the comprehensive test resources are not used. This will inevitably lead to an increase in the number of comprehensive test equipment and equipment costs, which is not conducive to the reduction of equipment costs and the improvement of economic benefits.
