Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, a schematic diagram of a logical structure of a railway electrification section cable anti-interference system provided by the present application is shown, the railway electrification section cable anti-interference system includes a station equipment room 11, a station power supply room 12, a trackside device 13 and an outdoor cabinet 14, and the outdoor cabinet 14 is arranged at a close distance beside the trackside device 13.
Wherein, the station equipment room 11 includes an electric control device 111, and the outdoor cabinet 14 includes an electric control device 141 and a transformer 142.
As shown in fig. 1, the electric control device 111 in the station equipment room 11 is connected to the electric control device 141 in the outdoor cabinet 14 through a control electric line 1, the electric control device 141 in the outdoor cabinet 14 is connected to the trackside equipment 13 through a short-distance line 3, the control electric line 1 is an induced electromotive force suppressing line and the control electric line 1 is a non-aluminum-sheathed signal cable line.
The station power supply room 12 is connected with a transformer 142 in the outdoor cabinet 14 through a power supply line 2, the transformer 142 in the outdoor cabinet 14 is connected with the trackside equipment 13 through the short-distance line 3, and the power supply line 2 is a non-aluminum sheath signal cable line.
The operation information of the electric control device 111 in the station equipment room 11 is transmitted to the electric control device 141 in the outdoor cabinet 14 through the control electric line 1, so that the electric control device 141 in the outdoor cabinet 14 operates according to the operation information of the electric control device 111 in the station equipment room 11 to control the trackside equipment 13.
In the present application, the trackside equipment 13 may be specifically, but not limited to: semaphores, switches, or track circuits.
In this application, no longer adopt the scheme that power supply line 2 and control circuit 1 unify, but with power supply line 2 and control circuit 1 separation, power supply is only realized to power supply line 2, and control circuit 1 only transmits control information.
After the power supply line 2 and the control line 1 are separated, the control line 1 needs to be redesigned to meet the engineering requirements of the control line 1 and to reduce the number of cable cores of the control line 1 as much as possible. For example, when the trackside equipment 13 is a traffic signal, the control circuit 1 is specifically a traffic signal lighting circuit, and a traffic signal lighting circuit newly designed is shown in fig. 2.
In the application, by utilizing the relatively concentrated characteristic of the trackside equipment 13 of the railway station, a plurality of outdoor cabinets 14 which are arranged beside the trackside equipment 13 in a short distance are added, and the electric control devices and the transformers are placed on the outdoor cabinets 14 in a concentrated manner. Since the distance between the outdoor cabinet 14 and the trackside equipment 13 is close, the short-distance line 3 led out from the outdoor cabinet 14 does not need to be shielded by induced electromotive force, and therefore, an aluminum sheath shielding layer is not needed to be adopted for the short-distance line 3.
The power supply line 2 is separated from the control line 1, control information is transmitted from the control line 1, and the power supply line 2 supplies power to the trackside equipment 13. Although the control circuit 1 transmits control information, it may be an induced electromotive force suppressing circuit and a non-aluminum sheath cable circuit, and the influence of the induced electromotive force can be reduced without using an aluminum sheath shielding layer. Because the power supply line 2 does not transmit control information and does not need to consider the influence of induced electromotive force on the transmission of the control information, the power supply line 2 does not need to adopt an aluminum sheath shielding layer.

Furthermore, the lines of the electrified railway section do not need to adopt an aluminum sheath shielding layer, and the induced electromotive force of the cable does not need to be calculated according to specific engineering parameters such as the ground conductivity, the approach length and the like, so that the type of the cable is selected, and the complexity of design is reduced.
In the present application, if the electric control device 111 in the station equipment room 11 is a computer interlock or a computer interlock device of a full electronic type, the control electric line 1 may be an optical communication line or a wireless communication line. Because the problem of induced electromotive force interference does not exist in optical communication or wireless communication, an optical communication line or a wireless communication line can be used as the control circuit 1, an aluminum sheath cable line is not needed to be used as the control circuit 1, and the railway engineering cost is reduced.
In this application, if the electric control device 111 in the station equipment room 11 is a relay interlock device, the following scheme may be adopted to reduce the influence of the induced electromotive force, and the scheme is specifically: the control electric line 1 is a composite sheath signal cable, the electric control device 111 in the station equipment room 11 is an electric control device adopting a terminal induced voltage suppression technology, and the electric control device 141 in the outdoor cabinet 14 is an electric control device adopting the terminal induced voltage suppression technology.
