一种新型防爆柴油机车安全保护系统设计

针对传统的防爆柴油机车安全保护系统采用集中控制方式而存在很难增加监测点及输出控制点的问题,设计了一种基于CAN总线及采用分布式控制方式的新型防爆柴油机车安全保护系统。该系统中的智能监控单元、显示器、继电器控制箱、总线信号转换器、开关量采集单元通过CAN总线组成分布式网络拓扑结构,实时监测机车在行驶过程中的各种状态以及驾驶员输入的信号,实时显示特定参数,并根据所监测到的状态和预先制定的逻辑关系对继电器的输出做出相应控制,从而保证了机车安全、稳定运行。井下工业性试验结果表明,该系统电气性能可靠、故障率低,满足矿用车辆的设计要求。

Design of a new type of safety and protection system of explosion-proof diesel locomotive

In view of problem that it is difficult to add monitored points and output control points with centralized control mode in traditional safety and protection system of explosion-proof diesel locomotive,a new type of safety and protection system of explosion-proof diesel locomotive based on CAN bus and distributed control mode was designed.In the system,intelligent monitoring unit,display,relay control box,bus signal converter and switch signal collection unit are compose of distributed network topology through CAN bus to real-timely monitor each state in running process of the locomotive and input signal by driver,real-timely display certain parameters and make relative control on output of relay according to monitored state and logic relation drafted in advance,so as to ensure safe and stable running of the locomotive.The result of underground industrial test showed that the system meets with design requirement of mine vehicle with reliable electrical performance and low fault rate.
