Embodiment 1

[0056] figure 1 It is a block diagram of a train pre-warning system according to an embodiment of the present application.

[0057]The aggressive advance warning system provided by this embodiment is applied to the locomotive as the own train, that is, located at the forefront of the train that needs to be warned, so as to ensure that it can smoothly receive the wireless signal sent by the preceding vehicle. Here, the device for sending wireless signals by the vehicle in front may be a dedicated transmitter for sending wireless signals of a preset frequency.

[0058] like figure 1 As shown, the pre-warning system specifically includes a first processor 10 , a configuration device 20 , a signal receiving circuit 30 and an alarm circuit 40 . Wherein the first processor is respectively connected with the configuration device and the signal receiving circuit, and the signal receiving circuit is also connected with the alarm circuit.

[0059] The configuration device can be unde...

Embodiment 2

[0079] Figure 7 It is a block diagram of another train pre-warning system according to the embodiment of the present application.

[0080] like Figure 7 As shown, compared with the previous embodiment, the aggressive advance warning system provided by this embodiment has added a signal transmitting circuit 50. In this embodiment, the first processor is also provided with a second control instruction output terminal 13, and the second control instruction The output end is connected with the signal transmitting circuit.

[0081] Because the system adds a signal transmission function, the configuration device here also outputs transmission frequency configuration parameters under the control of configuration instructions input by the user, and the transmission frequency configuration parameters are output to the first processor. The first processor will output a transmission frequency configuration instruction according to the transmission frequency configuration parameter. ...

Abstract

The invention discloses a system for early warning of overrunning of a train. The system comprises a first processor, a configuration device, a signal receiving circuit and an alarm circuit. The configuration device is used for outputting a receiving frequency configuration parameter to the first processor; the first processor is used for outputting a receiving frequency configuration instructionmatched with the receiving frequency configuration parameter to the signal receiving circuit according to the receiving frequency configuration parameter; the signal receiving circuit receives and amplifies a wireless signal transmitted by a front train based on the receiving frequency configuration instruction to obtain a vehicle distance signal; and the alarm circuit is used for outputting vehicle distance information reflecting the distance with the front train according to the intensity of the vehicle distance signal. A driver can clearly master the distance between his train and the fronttrain through the vehicle distance information, and therefore, the rear-end collision accident of the train can be effectively avoided.

Description

technical field [0001] The present application relates to the technical field of railways, and more specifically, relates to a pre-warning system for trains. Background technique [0002] For trains running in the same direction on a line, the two trains are generally on the same track, and there is no way to miss the train or make a detour. Therefore, they must pass in sequence at a certain speed to avoid rear-end collisions. In order to avoid train rear-end collision, the track circuit is generally used on the railway to indicate the position of the front car to the rear car at present, and the light signal displayed by the track circuit reminds the rear car to slow down or stop. But once the track circuit breaks down, the car behind cannot be prompted, which may lead to a rear-end collision. Contents of the invention [0003] In view of this, the present application provides a pre-warning system for trains, which is used to remind the train of the distance from the pre...
