Telegraph keying signal transmission processing system having adjustable acquisition/reception frequencies and method

Abstract

The invention discloses a telegraph keying signal transmission processing system having adjustable acquisition / reception frequencies and a method and belongs to the telegraph technology field. The system comprises a computer, a communication unit, a keying signal acquisition unit and telegraph keying equipment which are in communication connection, and is for acquiring, transmitting and storing button states of multiple keying equipment in real time, the keying signal acquisition unit comprises an acquisition frequency setting module and a signal acquisition module, the communication unit comprises a caching computing module, a first communication module, a caching module and a second communication module, and the computer comprises a reception frequency setting module and a second data packet reception module. Through dynamic setting of the acquisition frequency of the acquisition equipment and the reception frequency of reception equipment, the acquisition and reception frequencies can be independently and dynamically adjusted to satisfy different-scale and quality requirements in a telegraph operator training system.

Description

technical field [0001] The invention relates to a telegraph keying signal transmission and processing system and method capable of adjusting collection and receiving frequencies, and belongs to the field of telegraph technology. Background technique [0002] In the network training system for telegraphers, keying devices of different scales, such as 36, 72, 144, and 288 channels, can be provided. The practical application shows that the acquisition frequency of 1000 / s (that is, sampling once in 1ms) can basically restore the square wave signal of the key state without distortion, and the acquisition frequency of 2000 / s (that is, sampling once in 500us) can achieve better results. If high-frequency (500us) acquisition is used, then in the case of access to many keying devices (such as 288 channels), the burden on the communication network and the computer will increase sharply, so that it is too late to deal with frequent communications and calculations. not working properly...

AI Technical Summary

Problems solved by technology

If high-frequency (500us) acquisition is used, then in the case of access to many keying devices (such as 288 channels), the burden on the communication network and the computer will increase sharply, so that it is too late to handle frequent communications and calculations. not working properly

However, the existing operator training system often adopts a fixed acquisition frequency, which is difficult to meet the needs of different scales and different signal acquisition quality
