a signal processor

Abstract

The present invention provides a signal processing system, including: an input interface for receiving level signals and dry node signals; a complex programmable logic circuit board for receiving level signals, processing the level signals and encoding to obtain switching values Output signal; the relay circuit board is used to receive the dry contact signal, amplifies the dry node signal and transmits it to the complex programmable logic circuit board for processing to obtain the relay output signal, and amplifies the relay output signal; the output interface is used for output The switch value output signal and the relay output signal, wherein, the complex programmable logic circuit board and the relay circuit board are connected through a data flat cable. The signal processor simplifies and unifies the communication data interface between it and each subsystem, combines the working characteristics of the core logic control device, and simplifies the manual intervention process as much as possible, thereby improving the degree of automation control of the overall system and providing a one-key The realization of beam tuning function provides basic equipment.

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
