Abstract
The utility model discloses a control system used for a medical linear accelerator. The control system used for the medical linear accelerator comprises an operation keyboard, a display and a mainboard. An industrial control computer mother board, a CPU card, an A/D industrial control card, an AD/DC interface board, a timing interruption board and an I/O card are arranged on the mainboard, and a CPLD chip, and an output interface circuit and an input interface circuit connected with the CPLD chip are integrated in the I/O card; an interlocking signal is inputted to the CPLD chip via the input interface circuit, and a beam-out control signal of the CPLD chip is outputted via the output interface circuit; the A/D industrial control card is connected with the AD/DC interface board, and the CPU card is connected with the operation keyboard and the display. According to the utility model, the control system used for the medical linear accelerator is based on a CPLD mode, and programs are burned to the CPLD chip, so that the functions of a previous I/O finished board card can be realized; moreover, the functions, such as signal conversion, etc., and the CPLD chip are integrated on the mainboard, so that the flexibility is improved, the programs are burned according to demands to thereby reduce the wiring, the interference is reduced, and the stability is improved.
Description
Technical field
This utility model relates to medical apparatus and instruments, and is especially a kind of for the control system on the clinac.
Background technology
Medical electronic linear accelerator is that a kind of being used for carried out radiocurable particle accelerator device to tumor, and utilization has the microwave electric field interaction of high energy electron (speed reaches subvelocity of light) with the HIGH-POWERED MICROWAVES of certain energy, thereby obtains higher energy.At this moment the speed of electronics increases not quite, mainly is that quality constantly becomes greatly.(Einstein theory).Electronics is directly drawn, and can do the treatment of electronics line.The electronic percussion heavy metal target produces bremstrahlen, and the above X ray of emission MeV level is done the treatment of X line.Electron linear accelerator has mainly comprised accelerating tube, high-power microwave source and Wave guide system, ray expansion and guard system and control system.Accelerator control system mainly to accelerator go out beam control system, motor control, and to the interlock protection of personnel and equipment.Have the connection input-output equipment of acceleration-controlled system now, the I/O card of buy product, be inserted on the mainboard, also need in addition oneself to make work such as level conversion, signals collecting, make these signals can allow the I/O card identify.More complicated in control has been used many integrated circuit boards, and a lot of lines are arranged, and interference is arranged, and uses finished product I/O plate underaction, and the I/O plate generally is 24 and 32 the tunnel, but sometimes only need connect several roads of minority, and unnecessary has all wasted.
Summary of the invention
Technical problem to be solved in the utility model provides and has a kind ofly reduced line for the control system on the clinac, has reduced interference, has improved stable.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of for the control system on the clinac, comprise operation keyboard, display and mainboard, described mainboard is provided with industrial computer motherboard, CPU card, A/D industry control card, AD/DA interface board, timing interruption board and I/O card; Be integrated with CPLD chip and the output interface circuit and the input interface circuit that are connected with described CPLD chip in the described I/O card, interlocking signal is input in the CPLD chip by input interface circuit, and the beam control signal that goes out of CPLD chip is exported by output interface circuit; Described A/D industry control card is connected with the AD/DA interface board, and described CPU card is connected with display with operation keyboard.Adopt the CPLD mode now, program is fired in the chip, can realize the function of I/O finished product integrated circuit board in the past, and functions such as conversion of signals and CPLD chipset be incorporated on the mainboard motility raising, need several roads just to fire the program on several roads, reduced line, reduced interference, stability has also improved.
The beneficial effect that this utility model compared with prior art brings is:
This utility model adopts the CPLD chip to replace general-purpose industrial controller I/O integrated circuit board by programming CPLD chip, program is fired in the chip, can realize the function of I/O finished product integrated circuit board in the past, and functions such as conversion of signals and CPLD chipset be incorporated on the mainboard, motility improves, and needs several roads just to fire the program on several roads, has reduced line, reduced interference, stability has also improved.
Description of drawings
Fig. 1 is this utility model structured flowchart.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description.
As shown in Figure 1, a kind of for the control system on the clinac, comprise operation keyboard, display and mainboard, described mainboard is provided with industrial computer motherboard, CPU card, A/D industry control card, AD/DA interface board, timing interruption board and I/O card; Be integrated with CPLD chip and the output interface circuit and the input interface circuit that are connected with described CPLD chip in the described I/O card, interlocking signal is input in the CPLD chip by input interface circuit, and the beam control signal that goes out of CPLD chip is exported by output interface circuit; Described A/D industry control card is connected with the AD/DA interface board, and described CPU card is connected with display with operation keyboard.Adopt the CPLD mode now, program is fired in the chip, can realize the function of I/O finished product integrated circuit board in the past, and functions such as conversion of signals and CPLD chipset be incorporated on the mainboard, motility improves, and needs the youngster road just to fire the program on several roads, has reduced line, reduced interference, stability has also improved.
