TACAN control system based on DSP

Abstract

The invention discloses a TACAN control system based on a DSP. A core portion of a main control unit is a DSP chip TMS320C6000, and a peripheral circuit of the DSP chip comprises a TL16C754, a CPLDC208, a FM22L16 and a FLASH_SST39VF040 and is connected with a DSP data bus and an address bus through EMIF interfaces. The CPLDC208 and the FM22L16 are connected with the DSP chip TMS320C6000 through buses and the EMIF interfaces. Through hardware programming, the decoding function of the CPLDC208 is used in cooperation with the TL16C754 so that crystal oscillation of 11.0592MHz can be adopted, asynchronous serial interfaces of 12 routes of RS232 are expanded, and meanwhile the CPLDC208 controls the I/O high electric level and the I/O low electric level through an emitter following circuit 2N222 so as to control the device state. The main control unit obtains various monitoring parameters from the monitoring unit, obtains working state information of all working units from each working unit plate, obtains human interference instructions from a keyboard and a switch on a control panel, and judges thresholds of the various obtained monitoring parameters, and when the thresholds are exceeded, an audible and visual alarm is given, dual-machine conversion operation is executed, and working parameters of the system and the units are set and modified. The TACAN control system has the advantage that instantaneity of the control system is achieved through the rapid running capacity of the DSP.

AI Technical Summary

Benefits of technology

This technology allows for better control over complex systems by utilizing specialized hardware components called Digital Signal Processors (DSPs). These processors have quick processing capabilities that allow them to handle data quickly while still providing accurate results.

Problems solved by technology

This patented describes how current systems use timers for controlling work units within their own computer network. However, these timing components have limitations that make them slow down over time due to processing delays caused by communication between devices across multiple networks.
