【摘要】：现代加速器系统是一个庞大的系统工程,它包含了许多不同种类的设备,这些设备需要长期稳定而安全的运行才能保证加速器的正常工作和供束。由于设备众多,故障在所难免,因此,对这些设备的工作状态进行实时检测与报警就显得十分必要。在加速器运行期间,如何将这些设备出现的故障报警信息及时有效的通知值班人员,并及时得到处理解决,进而减少因设备故障造成的损失是本课题研究的主要内容。兰州重离子加速器由ECR离子源、SFC注入器、SSC回旋加速器、CSR冷却储存环等主要设施组成。在现有加速器装置上已经提供了分离的如漏水监测、水位水压监测、磁铁温度检测、动力线感温报警等系统。在加速器运行期间,由于加速器值班人员的主要专注焦点在于束流关系密切的磁铁电压、电流、束诊等相关参数上,经常忽略了这些起支撑作用的报警监测系统的有关信息,使这些支撑系统所发生的故障或报警没有得到足够的重视,如果任其发展而不对这些报警进行处理,将会引起机器故障,严重时会损坏设备,造成财产损失。这些监测系统中所监测到的报警信息一般只在分离的中控室监测屏幕上进行相应提示,一旦发生报警,值班人员并不能及时看到这些信息。为了能够把这些系统中的监测情况及时有效凸显,在故障出现时及时通知并“强迫”当前值班人员查看故障所在,本课题提出了一体化综合报警平台的设计。本综合报警平台是集成了漏水、温度、水压、液位等八种监测系统于一体的综合报警平台;实现了在某一监测子系统有报警出现,该平台能够立即凸显相应的监测系统的报警信息,通过声光报警方式达到及时通知并“强迫”值班人员处理具体故障的目的。综合报警平台采用NET+MSP430+CPLD的架构,集成了A/D、D/A转换,数字状态量监测控制、远程开关量控制等的应用,其ADC和DAC模块的积分非线性度分别好于0.4%和0.2%,数字量控制能够满足设计要求,通过现场测试和使用,达到了综合报警的目的。在本课题研究过程中还扩展应用VHDL语言,对其他课题实现了两种不同频率的正弦波信号的精确相位捕捉和任意两相位点的匹配设计,现场测试达到预期目标。
[Abstract]:Modern accelerator system is a huge system engineering, it contains many different kinds of equipment, these equipments need long-term stable and safe operation to ensure the normal operation of accelerator and beam supply. Because of the large number of equipments, it is necessary to detect and alarm the working state of these equipments in real time. During the operation of the accelerator, it is the main content of this research that how to notify the alarm information of these equipments in time and effectively, and deal with the problems in time, and then reduce the loss caused by the failure of the equipment. The heavy ion accelerator in Lanzhou is composed of the CSR cooling storage ring of the CSR cyclotron and SSC cyclotron, which is an ECR ion source and SFC injector. Separate systems such as leakage monitoring, water level and water pressure monitoring, magnet temperature detection, power line temperature alarm and so on have been provided on the existing accelerator devices. During the operation of the accelerator, since the main focus of the accelerator shift personnel is on the closely related parameters such as the magnet voltage, current, beam diagnosis and so on, the relevant information of the supporting alarm monitoring system is often ignored. The failure or alarm of these support systems has not been paid enough attention to. If we let them develop and do not deal with these alarms, it will cause machine failures, damage equipment and cause property losses. The alarm information monitored in these monitoring systems is usually only prompted on the monitor screen of the separated central control room. Once the alarm occurs, the staff on duty cannot see the information in time. In order to show the monitoring situation in these systems in time and effectively, to notify the failure timely and "force" the current duty personnel to check the fault location, this paper puts forward the design of the integrated alarm platform. The integrated alarm platform is a comprehensive alarm platform which integrates eight monitoring systems such as leakage, temperature, water pressure, liquid level, etc. The platform can immediately highlight the alarm information of the corresponding monitoring system and achieve the purpose of timely notification and "forcing" the staff on duty to deal with specific failures by means of acousto-optic alarm. The integrated alarm platform adopts the architecture of net MSP430 CPLD, and integrates the applications of A / D / D / A conversion, digital state monitoring and control, remote switching control, etc. The integral nonlinearity of ADC and DAC modules is better than 0.4% and 0.2% respectively. The digital control can meet the design requirements and achieve the purpose of comprehensive alarm through field test and application. In the course of the research, the VHDL language is extended to realize the precise phase capture of two sinusoidal signals with different frequencies and the matching design of any two phase sites for other subjects. The field test achieves the desired goal.
