Problems solved by technology

[0003] At present, when the HDLC-CAN gateway equipment used in rail transit is in use, when the intensity of external electromagnetic interference is high, its signal propagation will be hindered to a certain extent. In order to strengthen the range of its signal propagation, it is necessary to It performs anti-external electromagnetic interference processing. Therefore, it is urgent to design a HDLC-CAN gateway for rail transit that can strengthen the signal range to solve the above problems

Embodiment 1

[0027] refer to Figure 1-4 , a HDLC-CAN gateway for rail transit that can strengthen the signal range, including a housing 1, a support structure is welded on the bottom inner wall of the housing 1, and a clamping structure is provided on the top side of the housing 1, and the clamping structure A gateway body 6 is placed between the bottom and the top of the supporting structure, and a wiring groove 13 corresponding to the wiring port of the gateway body 6 is opened on one side of the housing 1, and an anti-interference Plate 7, both ends of one side of the anti-interference plate 7 are provided with connecting ports 16, the material of the anti-interference plate 7 is nickel-zinc ferrite, and both ends of the anti-interference plate 7 and both sides of the housing 1 are provided with corresponding The corresponding limit hole, and the inner wall of the limit hole is plugged with a limit rod 17, one end of the limit rod 17 is welded with a pull plate 8, and both ends of one ...

Embodiment 2

[0034] refer to Figure 5 , a HDLC-CAN gateway for rail transit that can strengthen the signal range. Compared with Embodiment 1, this embodiment replaces the limiting hole, the limiting rod 17, the pulling plate 8 and the second spring 15 with a limiting groove 18 And the limit block, and the limit groove 18 is opened on the top of the inner wall on both sides of the housing 1, and the two ends of the anti-jamming plate 7 are welded with limit blocks inserted in the limit groove 18.

[0035] Working principle: when in use, the user uses the sliding connection of the slider in the limit groove 18 to move one end of the anti-jamming plate 7 without detaching the anti-jamming plate 7 from the housing 1, which is convenient for installation.

Abstract

The invention discloses a rail transit HDLC-CAN gateway capable of enhancing a signal range, which comprises a shell, a supporting structure is welded on the inner wall of the bottom of the shell, a clamping structure is arranged on one side of the top of the shell, and a gateway body is placed between the bottom of the clamping structure and the top of the supporting structure. A wiring groove corresponding to a wiring port of the gateway body is formed in one side of the shell, an anti-interference plate is placed on the inner wall, close to the top of the wiring groove, of the shell, connecting ports are formed in the two ends of one side of the anti-interference plate, the anti-interference plate is made of nickel-zinc ferrite, and corresponding limiting holes are formed in the two ends of the anti-interference plate and the two sides of the shell. According to the invention, the gateway body is buffered, the vibration frequency of the gateway body is reduced, the vibration amplitude during signal propagation is reduced, and anti-electromagnetic interference processing is respectively carried out on the wiring part and the periphery of the gateway body, so that the signal propagation of the gateway body is not too much interfered, and the signal propagation range of the gateway body is enhanced.

Description

technical field [0001] The invention relates to the technical field of gateways, in particular to an HDLC-CAN gateway for rail transit that can strengthen the signal range. Background technique [0002] Gateway is also called internet connector and protocol converter. The gateway implements network interconnection above the network layer and is the most complex network interconnection device, which is only used for the interconnection of two networks with different high-level protocols. Gateways can be used for both WAN interconnection and LAN interconnection. A gateway is a computer system or device that acts as a switch. Used between two systems with different communication protocols, data formats or languages, or even completely different architectures. . [0003] At present, when the HDLC-CAN gateway equipment used in rail transit is in use, when the intensity of external electromagnetic interference is high, its signal propagation will be hindered to a certain exten...
