Signal processor

Abstract

The invention provides a signal processing system, which comprises an input interface, a complex programmable logic circuit board, a relay circuit board and an output interface. The input interface isused for receiving a level signal and a dry node signal; the complex programmable logic circuit board is used for receiving the level signal, processing the level signal and encoding the level signalto obtain a switching value output signal; the relay circuit board is used for receiving the dry node signal, amplifying the dry node signal, then transmitting the dry node signal to the complex programmable logic circuit board to be processed to obtain a relay output signal, and amplifying the relay output signal; the output interface is used for outputting the switching value output signal andthe relay output signal; and the complex programmable logic circuit board and the relay circuit board are connected through a data flat cable. A signal processor simplifies and unifies the communication data interfaces of the signal processor with all subsystems, by combining with working characteristics of a core logic control device, the manual intervention process is simplified as far as possible, thus the automatic control degree of the whole system is increased, and basic equipment is provided for realizing of the terminal one-key beam modulation function of a medical accelerator.

Description

technical field [0001] The invention relates to the field of system control, in particular to a signal processor. Background technique [0002] The medical heavy ion therapy device is the largest medical device at present. Each medical heavy ion therapy device has a treatment terminal system, which is located at the end of the accelerator. The more efficient the beam is used, the lower the overall cost of treatment. Therefore, each treatment terminal system has a dedicated equipment centralized control system. [0003] The centralized control system consists of two specific devices: the control handle signal processor and the handle controller. Among them, the control handle signal processor is a signal acquisition and data encoding device, and its main function is to collect real-time data from each subsystem of the accelerator. The key working status signals, after the software system analysis, coordinate the work of all the controlled equipment in the system according t...

Problems solved by technology

[0004] However, at present, the signal processor of the control handle uses a large number of scattered devices such as industrial computers, PLCs, and various backplane industrial control boxes to cooperate to complete the task of information collection and control command delivery. The system integration degree is not high, and the signal acquisition and processing methods are not uniform. , and the ways of summarizing the information of each subsystem are not the same, which makes the whole centralized control system more complicated and less efficient, and rarely viewed from the perspective of operators
