使用系として動作を開始する。When a failure occurs in the active system, if a coincidence signal is not issued in the standby system, there is a delay in the recovery of the coincidence relay 14 compared to the recovery of the normal relay 12, and the standby system is activated after the switching conditions are achieved. Switch to . Here, since the standby system has not outputted the coincidence signal b3, it performs initial processing and then starts operating as the use system.

In these cases, train operations may be disrupted or passengers may not be able to be taken, or the probability of this happening is low given the configuration of the device.

滑に連動制御をすることができる。"Effects of the Invention" According to the parallel multiplex electronic interlocking device and its switching method according to the present invention, by configuring the device into two simple systems and constantly monitoring whether the active system and the standby system match, If they match at the time of system switching, the switching is done instantly without any downtime, so there is a low-cost device, so if there is a failure 119, it will not interfere with the train movement. Smooth interlock control is possible.

切換方法。[Claims] 1. The interlocking control system is configured as a dual system of a first interlocking control system and a second interlocking control system, and when one system is used, the other system is operated simultaneously, In a parallel multiplex electronic interlocking device that can be switched in the event of a failure, etc., a first interlocking control system and a second interlocking control system are connected, and the control output of one of the systems is controlled via a switching means. At the same time, the output to the controlled object is connected to be fed back to either system, and each interlocking control system has a normality verification section that verifies the normal operation of its own system, and a normality verification section that verifies the normal operation of its own system based on feedback input. A coincidence verification section is provided for each system to verify consistency with other systems, and if one of the two interlocking control systems is the active system and the other system is the standby system, an abnormality has occurred in the active system. When the normal operation signal is no longer output from the normality verification section, a determination section that checks the normal operation signal of the standby normality verification section and the coincidence signal of the coincidence verification section and outputs a switching signal to the switching means. What is claimed is: 1. A parallel multiplex electronic interlocking device, characterized in that it is provided with a switching control section having a switching control section. 2 If the interlocking control system is configured as a dual system of the first interlocking control system and the second interlocking control system, and one system is the active system and the other system is the standby system, both systems must be operated at all times. This is a switching method for a parallel multiplex electronic interlocking device that enables switching to the standby system in the event of a failure in the used system, in which each system outputs its own normal operation signal, and the output of the used system is transferred to the standby system. A switching method for a parallel multiplex electronic interlocking device, in which consistency of operation is constantly monitored by feedback to the output of a standby system, and when the system is switched, the coincidence signal is obtained and switching is performed without momentary interruption.
