Abstract

The invention discloses a resistance-capacitance box with AC switch indication circuit operating state monitoring. The box comprises a resistance loop; the resistance loop comprises a resistor; one end of the resistor is connected to a first terminal through a first current sensor, the other end of the resistor is connected to a second terminal, and a signal of the first current sensor is sent bya first A / D conversion unit to a microprocessing unit after signal conditioning by a first signal conditioning unit. The resistance-capacitance boxcan solve the problem that monitoring the states of elements such as resistors, diodes, and cable lines which affect the working quality of an AC switch indication circuit , and determining the position of a switch by signal analysis are still vacant.

Description

technical field [0001] The invention relates to the technical field of railway signal equipment, in particular to a resistance-capacitance box with an AC switch indicating circuit working state monitoring. Background technique [0002] With the rapid development of my country's railways, the requirements for the safe and efficient operation of railways are getting higher and higher. Railway signal equipment plays a very important role in the entire railway operation. A small fault may disrupt the traffic order and ensure safety. Not guaranteed. At present, the maintenance of railway signal equipment generally adopts the method of regular inspection and replacement, but the status during operation is unknown, and because there are many types and quantities of railway signal equipment in the mechanical room, even if the equipment fails, it is difficult to find , which greatly reduces the efficiency of fault handling. The railway turnout display circuit is used to reflect the ...
