1仿真试验存在的必然性随着铁路发展的加速,信号设备的更新速度也日益加快,各种设备改造周期逐步缩短。对计算机联锁车站而言,信号设备的改造一旦涉及联锁软件的变动,就必须进行联锁试验。计算机联锁不同于继电联锁,继电联锁只在继电电路改造的局部进行联锁试验即可,但计算机联 Inevitable Necessity of Simulation Test With the acceleration of railway development, the updating speed of signal equipment is also accelerating day by day, and the transformation cycle of various equipment is gradually shortened. For computerized interlocking stations, the interlocking test must be carried out once the alteration of signal equipment involves the change of interlocking software. Computer interlocking is different from the relay interlock, relay interlock only in the relay circuit to transform the local interlock test can be, but the computer
