Analog signal generator

Abstract

The invention discloses an analog signal generator, which comprises a central processing unit, a storage unit (1) of the central processing unit and a work information generating unit (6), wherein the central processing unit and the storage unit (1) thereof are electrically connected with a frequency signal generating unit (2), a voltage signal generating unit (3), a current signal generating unit (4), a speed signal generating unit (5), the work information generating unit (6), a signal conditioning unit (7), an external interface (8) and a display (9), wherein the signal conditioning unit (7) is further electrically connected with the frequency signal generating unit (2), the voltage signal generating unit (3), the current signal generating unit (4), the speed signal generating unit (5) and the external interface (8). The invention has the advantages of high integration degree, convenient installation, simple operation and high reliability degree. The analog signal generator is suitable for manufacturing enterprises and scientific research units of various large-scale transport equipments.

Description

technical field [0001] The invention relates to a signal generator, in particular to an analog signal generator used in the ground static test of an automatic safety protection device for large-scale transportation equipment. Background technique [0002] All kinds of large-scale transportation equipment such as spacecraft, ships, railway locomotives and EMUs need to do static tests when they are newly manufactured or overhauled or routinely inspected. The static test of various transportation equipment is to simulate the equipment when it is put into operation. various situations that may be encountered. Taking the railway locomotive as an example, the static test items include the status signal of the locomotive itself, the signal of the railway line and other safety signals that must be considered. At present, the static test of a railway locomotive needs multiple equipments to work together. Although it can meet the test requirements in some cases, there are obvious sho...

AI Technical Summary

Problems solved by technology

At present, the static test of a railway locomotive needs multiple equipments to work together. Although it can meet the test requirements in some cases, there are obvious shortcomings: multiple equipments work together, and it takes a lot of preparation time to install and debug the test equipment. , the operation is complex, the reliability of the test is not high, and the equipment investment and maintenance costs are high
