Problems solved by technology

[0002] The reliability of railway communication signal transmission is the key factor for the normal operation of railway devices. The existing semi-automatic block information transmission is based on cable transmission. Due to factors such as on-site construction, cable damage often occurs, resulting in signal failure. Normal transmission seriously affects normal railway transportation and brings serious economic losses to the country
[0003] The existing block signal transmission conversion device is relatively simple, and only uses two-way signal transmission, that is, mainly audio 64K. When the audio channel fails, it is switched to the existing cable for signal transmission, and there is no integrity detection of the cable. For example, the cable A series of possible faults such as open circuit and cable short circuit are checked

Embodiment Construction

[0020] As shown in Figure 1, it is a specific embodiment of the present invention.

[0021] The railway-specific semi-automatic blocking information transmission conversion device of the present invention is applied to two 64D semi-automatic blocking machines along the railway line and separated by a certain distance. It adds a supporting transmission device to each semi-automatic blocking machine, and two transmission devices An optical cable is also connected in parallel on the basis of the original cable connecting the semi-automatic blocking machine, and the optical cable can include a dual-audio main channel, a dual-audio standby channel and an Ethernet channel. Figure 2 is a comparison diagram of the jamming signal and the transmission equipment signal. In order to meet the transmission requirements of the railway signal, the delay requirement is less than 300ms.

[0022] As shown in Figure 3, the transmission equipment mainly includes three parts: a power supply module,...

Abstract

The invention discloses a railway-dedicated semiautomatic device for transmitting and converting blocked information, which at least comprises two semiautomatic blocking machines situated along the railway between two stations and one section therebetween. The two semiautomatic blocking machines are equipped with a transmission device connected thereto respectively; optical fiber cable and electric cable are connected in parallel between the first transmission device and the second transmission device. The optical fiber cable comprises double-audio main channel, double-audio backup channel and Ethernet channel; the transmission device includes power module, management module and transmission model. The invention adopts electric cable and optical fiber cable to transmit blocking signal simultaneously.
