Railway signal relay real-time positioning monitoring system

Abstract

The invention discloses a railway signal relay real-time positioning monitoring system which comprises a filtering receiving module and a denoising following module, the filtering receiving module receives a position signal output by a railway signal relay position information acquisition module; the filtering receiving module is connected with the denoising following module; the denoising following module is provided with a capacitor C6, a capacitor C7, a resistor R13 and a resistor R14 to form a denoising circuit to reduce signal noise. The capacitor C6 is used as a decoupling capacitor; thenoise ratio of the source signal is reduced; secondary signal is adopted for compensation of primary signal, in order to further ensure the accuracy of secondary signal compensation. The control electrode of a silicon controlled rectifier D6 is used for detecting the output signal potential of an operational amplifier AR3; and if the signal is too large, the silicon controlled rectifier D6 is triggered to be conducted, the power supply + 3.3 V is fed back to the base electrode of a triode Q1 after voltage division by the resistor R11, and finally the signal is sent to a railway signal relay real-time positioning monitoring system terminal through a signal emitter E1, so that the interference of a high-power signal emitter of railway station port equipment is reduced through amplitude modulation and de-noising.

[0002] Railway signal relays refer to special electromagnetic switching devices in various types of railway signal equipment or systems. Reliability and safety in use are necessary requirements to ensure the normal operation of various automatic control and remote control signal equipment. Therefore, railway signal relays Strict requirements are put forward; the contact system must act consistently, reliably and accurately; have a long service life; have sufficient functions of closing and breaking circuits; maintain high electrical insulation strength in the case of large changes in external temperature and humidity; It has stable time characteristics and electrical parameter characteristics. However, the railway signal relay also needs to ensure real-time positioning function, which is convenient for timely and regular maintenance, especially when there is a fault, it needs to be located and repaired at the first time. Due to the environmental factors of the railway signal relay, it will be affected by the railway station. The interference of the high-power signal transmitter of the equipment will affect the positioning accuracy, thereby delaying the positioning and repair time, and even causing serious consequences
