The nature of the way in which the route is recorded is whether the train is in or out of the way. Settings: A set of FJ circuit is set in each throat, which is set in the direction of F, including: LJJ, LFJ, DJJ, DFJ and four FJ. The direction of the route is divided by the direction of the car and the direction of the car. The nature of the entrance is divided into two classes: the entrance of the train and the transfer of the car. A throat area, can be set up four FJ respectively with the train car direction into the road, the obligatory direction approach, shunting car direction route and shunting start direction into four types into the road, can complete record into the road running direction and nature two tasks into the road. The technique requires 1. In order to record the direction of the road, the excitation circuit of the corresponding directional relay must be connected to the front of the relay. If the car is in the direction of the road, the excitation circuit is connected to the relays of the relays. If the car is in the direction of the car, the excitation circuit will be connected to the relays. The direction is recorded in the direction of the directional relay which is attracted by excitation. In order to record the nature of the route, the trains directional relay will be connected to the excitation circuit by the starting point of the train. The relay1 direction relay should be connected to the starting point of the road by the starting point of the car. The properties of the road are recorded by the directional relay of excitation. 3. Due to the directional relay in the entire process of routing, to participate in the work, so before all approach has not yet been selected, for directional relay must be kept in the state. And demand in the same throat only allowed to choose a route at the same time (the same homog
