The present disclosure relates to a portable safety terminal based method for processing rail transit resources, and a system for the method. The method includes: in a degradation mode, performing interaction between a portable safety terminal and a wayside controller; providing a driver with safety display of an environment where a train is located, and obtaining a location of the train and information of a relationship between a front train and a rear train; and providing the driver with a means to apply for line resources, such that the driver can, according to the train environment, autonomously apply for the line resources, and release the resources for use by subsequent trains after driving the train to pass through a zone. Compared to the prior art, the present disclosure has the advantages of improving the safety of train driving and field maintenance operation, etc.

A concealed asset locator includes an enclosure with multiple external surfaces, wherein an external surface is configured as reflective surface, an electric notification device, a receiver relay positioned inside the enclosure and electrically coupled to the notification device, wherein the receiver relay is configured to activate the notification device in response to a received transmitter signal.

The invention provides a signal redundancy control system. The system includes multiple first signal collecting devices, second signal collecting devices and a controller, wherein the multiple first signal collecting devices are configured to collect the dynamic information of default devices where the first signal collecting devices are located in real time; one second signal collecting device corresponding to each of the first signal collecting devices is disposed on each default device, and is configured to collect the dynamic information of the default device where the second signal collecting device is located in real time; the controller is configured to determine whether the first signal collecting devices include fault information or not, and positions each default device according to the dynamic information acquired by the first signal collecting devices or the second signal collecting devices.

A wireless target activation system for a train, the system including at least one computer programmed or configured to: receive at least one first target location and at least one second target location associated with a forward route of the train, wherein the at least one first target location is located before the at least one second target location on the forward route of the train; determine a gap time between when the leading edge of the train leaves the at least one first target location and is estimated to arrive at the at least one second target location based at least partially on a distance between the at least one first target location and the at least one second target location and a design speed; and based at least partially on the gap time, an allowable acceleration of the train, and a required warning time, generate an activation message configured to activate or cause the activation of at least one function associated with the at least one second target location.

A method for commanding a railway level crossing protection system comprising: a) activating a railway signal preventing a train from driving beyond a level crossing; b) detecting an incoming train approaching the level crossing and measuring a speed of said incoming train; c) calculating a waiting time, as a function of the train's measured speed; d) waiting until expiration of the calculated waiting time and, once said waiting time expires, sending an order to commute the protection system into the protected state; and e) querying the state of the protection system and if said protection system is found to have commuted into the protected state, deactivating said railway signal, and maintaining said railway signal in the activated state otherwise.
