Device and method for simulating speed output

Abstract

The invention provides a device and a method for simulating speed output. The device comprises a first processor, a second processor, a BCD (Binary-coded Decimal) transcoding seven-segment code converter, a gate array nixie tube address decoder, a nixie tube display, a first driver, a second driver, an I / O (Input / Output) interface module, an LED (light-emitting diode) lamp and a speed output mode selection switch, wherein the speed output mode selection switch is connected with the first processor; an output end of the first processor is connected with input ends of the first driver and the second driver respectively; an input end of the BCD transcoding seven-segment code converter, an input end of the gate array nixie tube address decoder and an output end of the first driver are connected with an input end of the I / O interface module; an output end of the second driver is connected with the LED lamp; and output ends of the BCD transcoding seven-segment code converter and the gate array nixie tube address decoder are connected with the nixie tube display. Every two I / Os form a pair of signal outputs, and the second processor adopts an interrupt mode to output a standard timing pulse signal, so that the speed accuracy is ensured reliably.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a device and method for simulating speed output. Background technique [0002] The current intelligent transportation and electronic police product industry is in a stage of rapid development in a very short period of time. It is for this reason that relative post-production and on-site installation and commissioning lack effective tools and means to ensure the quality of the produced products and projects. Lack of necessary dedicated standard signal sources for debugging and testing. At present, for this industry, there are no effective tools and means for product production and on-site debugging. [0003] In the existing product production and on-site debugging, most of them use some simple local methods to complete a small number of functional debugging. Such as: self-made manual analog ring coil board or driving various motor vehicles instead. Its main purpose is to ...

AI Technical Summary

Problems solved by technology

This method cannot produce a unified standard or a continuous and stable signal source, and cannot meet the consistent and repeatable signal output requirements

Such methods cannot meet and guarantee the progress and quality of subsequent product production and installation

Without unified standards and reference equipment, effective benchmark data cannot be provided for production and field personnel as a reference

[0004] Therefore, in actual work, the existing soil method has brought a lot of inconvenience and heavy work to the production and the scene.

In particular, the quality of the produced products cannot be guaranteed, which also brings great problems and hidden dangers to the on-site system debugging
