中文摘要:
      针对水下爆炸试验自由场压力、壁压、加速度等多种数据的测量需求,提出一种基于分布式测量技术的设计思路和测试方法,该方法充分考虑了水下爆炸试验测量通道多、实时性要求高、可靠性要求高等特点。分布式爆炸测量系统采用分布式测量方式和CAN总线通讯方式对系统测量单元的数据采集、传输及故障上报等进行管理和控制,提高了系统工作可靠性,保证了测量数据的可靠回收。在实验室条件下,采用模拟的两种触发信号,分别对系统触发采集的可靠性进行测试,实验证明系统采用其中任一触发信号均能可靠启动;该系统已成功应用于爆炸试验测量,较之其它爆炸测量设备其使用更加灵活、简便、可靠。
英文摘要:
      In view of measurement requirements in the underwater explosion test such as free space pressure, wall pressure, acceleration, etc., putting forward the design train of thought and test methods based on the distributed measurement technique. The method fully considers measuring multi channel, high real time demand, high reliability demand in the underwater explosion test. By adopting distributed measurement way and CAN communications in distributed explosion measurement system, the data acquisition, transmission, and fault upload of measurement unit are managed and controlled. So the system reliability is improved, and measurement data collection is ensured. In laboratory, the reliability of trigger acquisition is tested with two simulated trigger signals. Experiments show that the system can be triggered reliably with any one trigger signal. This system is successfully applied to explosion test, it is more flexible, more convenient, and more reliable than other measuring equipments.
