Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] Such as figure 1 As shown, the present invention is applicable to a decoding device for railway point information, which includes a main operation unit 1 , a logic control unit 2 , a data input unit 3 , a main storage unit 4 , a power supply and monitoring unit 5 , and a display unit 6 . Wherein, the main operation unit 1 is connected with the data input unit 3 through a serial port. The connection between the main operation unit 1 and the main storage unit 4 includes two parts, wherein the control signal is connected to the main storage unit 4 through the logic control unit 2 , and the data is connected to the main storage unit 4 through the bus. At the same time, the main operation unit 1 is also connected to the display unit 6 through the logic control unit 2 . The external device can access the main storage unit through t...

The utility model discloses a decoding device applicable to the railway point-mode information, which comprises a main arithmetic unit, a logic control unit, a data input unit, a main memory cell, a power supply, a monitoring unit and a display unit; wherein, the data to be encoded is input into the main arithmetic unit through the data input unit; a corresponding control signal is generated by the main arithmetic unit through the logic control unit after the decoding of the data to be encoded; the message is sent to the main memory cell through the bus; the display unit is also connected with the output of the logic control unit; the main arithmetic unit generates corresponding control signal through the logic control unit, enabling the display unit to generate corresponding indication, so as to offer the current state of the equipment to the user. The power supply is connected with each unit to supply power for each unit and the monitoring unit is connected with the main arithmetic unit to conduct real-time monitoring over the master arithmetic chip. The utility model has the advantages of simple structure, low cost and power consumption, safety, reliability and high sensitivity.
Description
technical field [0001] The invention mainly relates to the control field of railway locomotive safety equipment, in particular to a decoding device suitable for railway point information. Background technique [0002] At present, with the smooth operation of the 200-kilometer EMU, more and more rely on ground point equipment to realize ground and vehicle information communication. According to the regulations of China Train Control System (CTCS), in addition to level 0, levels 1 and 2 have "balise as a supplement to continuous information", and levels 3 and 4 have "balise as a calibration device". It will become a necessary equipment for Chinese railways. At this stage, other types of point devices have also appeared in our country, but the coding is simple, the amount of information is low, the security is poor, and the frequency band is not uniform. It is far from suitable as a safety device (mainly providing ground information for the train monitoring system) The use of...
