Problems solved by technology

[0003]However, when the dual-current system vehicle fails to switch when driving in a non-electric area, it will cause the risk of aggressive advance of the dual-current system vehicle in different power supply voltage circuits. into the AC high-voltage circuit or the AC high-voltage power penetrates into the DC high-voltage circuit, causing damage to electrical components. Therefore, the emergency protection treatment after the failure of the dual-current vehicle switching in the non-electric zone is very important.

Embodiment 1

[0021] The emergency system for switching failure of dual-stream vehicles without electricity, such as figure 1 Shown: including a location module, a first detection module, a processing module, a prompt module and a second detection module, the location module obtains the real-time location information of the vehicle in real time, and the location module can use the existing fixed-position inductance coil as a ground beacon to identify the vehicle Real-time location information, the first detection module detects the switching failure signal when the vehicle is switched in the non-electric zone and sends it to the processing module, the first detection module includes a sensing unit, a receiving unit, a redundant sensing unit and a redundant receiving unit, the transmission The sensing unit detects the switching failure signal of the vehicle and sends it to the processing module. The sensing unit can be a vehicle-mounted sensor, such as a speed sensor and a ground beacon recei...

Embodiment 2

[0029] The difference from Embodiment 1 is that it also includes a communication module and a background monitoring module for redundant monitoring of switching failures in the non-electric zone. Redundant monitoring refers to a monitoring operation that is independent of the existing alarm system. When the operation feedback signal is When the switching of the non-electric zone is not completed, the processing module sends the switching failure record signal to the background monitoring module through the communication module, and shares the real-time position and real-time speed with the background monitoring module through the communication module; the background monitoring module judges the real-time location of the vehicle according to the failure record signal Position and real-time speed. When the real-time speed is zero, the background monitoring module sends an alarm message to the subsequent vehicle in the same direction as the vehicle.

Embodiment 3

[0032] The difference from Embodiment 1 is that before judging the failure cause information according to the handover failure signal and the location information, the processing module first judges the matching information between the handover failure signal and the location information, that is, judges whether the handover failure signal is caused by the handover failure operation of the location information. Yes, the matching information includes matching success and matching failure. When the matching information is matching success, the processing module judges the failure reason information. When the matching information is matching failure, the processing module suspends judging the failure reason information and sends an alarm signal to the background monitoring module.

[0033] Since the position of the ground beacon is fixed, when the switching failure signal is not caused by the switching operation at the corresponding ground beacon, for example, the switching failure...

Abstract

The invention relates to the technical field of rail train running control, in particular to an emergency system for switching failure of a non-power area of a double-current system vehicle. The emergency system which comprises a position module, a first detection module, a processing module and a prompting module. The position module obtains real-time position information of the vehicle in real time; the first detection module detects a switching failure signal when the vehicle is switched in the non-power area and sends the switching failure signal to the processing module, and the processing module obtains position information when receiving the switching failure signal and judges failure reason information according to the switching failure signal and the position information; and the processing module determines emergency processing information according to the failure reason information and sends the emergency processing information to the prompting module for prompting. According to the invention, emergency prompting can be carried out in time after the driving switching state of the non-power area is detected, and the follow-up rescue difficulty of the vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of rail train running control, in particular to an emergency system for switching failure of a dual-stream vehicle without electricity. Background technique [0002] Dual-current vehicles are vehicles that drive between different power supply voltage areas. A non-electric zone is set between the two power supply voltage areas as a transition zone, such as the non-electric zone between the AC power supply area and the DC power supply area, to protect the dual-current system vehicles. Various on-board electrical equipment during driving with different supply voltages. Since the dual-stream vehicle runs continuously and cannot stop halfway when passing through the non-electric zone, an important control link in the driving process of the dual-stream vehicle is the switching control of the non-electric zone. [0003] However, when the dual-current system vehicle fails to switch when driving in a non-electric ar...
