       狼的生存,就是在恶劣的环境中坚强地创造生存空间;狼的团体,就是在充满争斗的对手中组织强大的团队力量;狼的智慧,就是在强者之列不断竞争、超越。
       The Wolf's survival, is strong in the harsh environment to create living space; Group of Wolf is in the hands of full of struggle for organizing strong team force; The Wolf's wisdom, is the constant in the strong competition and beyond.
       在线式微机五防系统主要由五防工作站、在线式五防专用锁具、可遥控空气开关三部分组成;在线式五防系统与变电站自动化系统一体化配置,五防工作站能与操作员站切换/互为备用;在线式五防专用锁具、可遥控空气开关受监控五防及测控五防控制,并提供反映分、合状态的辅助接点。后台实行一体化五防即五防系统嵌入后台监控系统当中,实时从监控系统获取当前全站的遥信状态。正常情况下任何操作都需要操作票才能进行。未开操作票时,每个操作对象的监控操作允许标志位(JKCZ)均置0,程序根据五防逻辑关系,实时的计算每个操作对象的监控五防分允许标志(JKWF_EnaOpn)、监控五防合允许标志(JKWF_EnaCls),通过通讯报文将每个操作对象的实时允许信息发给测控装置。已开操作票时,后台将当前步骤操作对象的JKCZ置1,其他操作对象的JKCZ均置0;根据对当前操作对象的操作方式,来选择发JKWF_EnaOpn或者JKWF_EnaCls。后台具有临时解锁功能,可对某个操作对象临时解锁,解锁后将该操作对象的JKCZ、JKWF_EnaOpn、JKWF_EnaCls都置1。 
       On-line five prevention system is mainly composed of five workstations, five special locks, on-line can remote control air switch of three parts; On-line five prevention system and substation integrated automation system configuration, five as spare workstation can switch with the operator station/prevention; On-line five special locks, five prevention and control can be remotely monitored air switch five control, and provides the reflection points and status of auxiliary contacts. Background implements the integration of five against five system embedded in the background monitoring system, real-time current was obtained from the monitoring and control system of total station remote communication state. Any action needs to be operating normally votes. Not open operation, each action object monitoring operation allows flags (JKCZ) are 0, program according to the five logical relationship, real-time calculation of each action object five monitoring points allow marks (JKWF_EnaOpn) prevention, monitoring five or allow marks (JKWF_EnaCls), through the communication message will information to each action object allows real-time measurement and control device. Open operation ticket, the background will be the current step operation object JKCZ 1, other action object JKCZ s; According to the object for the current operation mode of operation, or to select the hair JKWF_EnaOpn JKWF_EnaCls. Background have temporary unlock function, can be for a temporary unlock operation object, unlock after the action object of JKCZ, JKWF_EnaOpn, JKWF_EnaCls 1, implement emergency single-step operation, in response to emergencies happen.
