Method and device for determining adjustment table of non-insulated track circuit

Abstract

The invention discloses a method and a device for determining an adjustment table of a non-insulated track circuit, which relate to the technical field of transportation and mainly aim at improving the design and construction efficiency of the non-insulated track circuit and ensuring the accuracy of the electrical characteristics of each equipment installation and debugging. The method includes: when receiving the non-insulated track circuit adjustment table determination instruction, according to the basic parameter set of carrier frequency, section length, sending cable length and receiving cable length, the corresponding relationship of preset carrier frequency-capacitance, Preset cable length-correspondence between analog network section range types, preset main rail voltage and current adjustment table, preset sending level adjustment table, preset receiving level adjustment table and preset analog network adjustment table, calculation or query A set of adjustment parameters for the track circuit; according to the set of adjustment parameters, an adjustment table for non-insulated track circuits corresponding to the track circuit is generated. The invention is suitable for determining the adjustment table of the non-insulated track circuit.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a method and a device for determining an adjustment table of a non-insulated track circuit. Background technique [0002] With the continuous development of information technology, the non-insulated automatic blocking system is widely used in the field of national railway and urban rail transit due to its advanced nature, reliability and stability. When debugging and designing non-insulated track circuits, a large number of wiring parameters and data such as compensation capacitance, cable simulation network, sending level, and receiving level are required. Due to the high technical standard and strict process in the construction process, it is necessary to determine the adjustment table of the non-insulated track circuit in advance during the construction process of the non-insulated track circuit, and then query the various wiring and data required for construction accor...

Problems solved by technology

However, the design and construction of railways is the construction of large and long trunk lines, most of which are hundreds of kilometers long. Therefore, the data information of the non-insulated track circuit adjustment table that needs to be determined is relatively large. If the non-insulated track circuit adjustment table is determined by the above method, it will consume More manual query and calculation time, and the query and calculation of a large amount of data information are prone to errors, resulting in a large amount of time spent on repeated calculations, resulting in low efficiency in determining the non-insulated track circuit adjustment table, resulting in the failure of the non-insulated track circuit Design and construction efficiency is low

In addition, the above method requires a high technical level of technicians. If the technicians do not understand the transmission characteristics of the track circuit properly or the gear position of the non-insulated track circuit adjustment meter selected is wrong, it will cause the error of the non-insulated track circuit adjustment meter. Accurate, resulting in improper adjustment of non-insulated track circuits, affecting the electrical characteristics of each equipment installation and commissioning
