Multifunctional circuit interface board applied to GYK equipment

Abstract

The invention discloses a multifunctional circuit interface board applied to GYK equipment. The circuit interface board comprises an European-style socket unit, an electromagnetic compatibility electromagnetic interference protection filtering unit and an aviation socket unit, wherein the aviation socket unit comprises a plurality of aviation sockets; each aviation socket is welded on a PCB through a wireless binding technology; according to the circuit interface board, a signal introduced by the aviation socket unit is subjected to electromagnetic interference protection filtering through theelectromagnetic compatibility electromagnetic interference protection filtering unit to be output through the European-style socket unit, or according to the circuit interface board, a signal introduced by the European-style socket unit is subjected to electromagnetic interference protection filtering through the electromagnetic compatibility electromagnetic interference protection filtering unitto be output through the aviation socket unit. Therefore, the circuit interface board provided by the invention not only improves the reliability of signal connection introduced to the PCB through the aviation socket, but also has the functions of lightning surge protection, rapid transient pulse group interference protection, electromagnetic anti-interference filtering and the like.

Description

technical field [0001] The invention relates to the technical field of wireless binding technology and signal anti-interference filtering, in particular to a multifunctional circuit interface board applied to GYK equipment. Background technique [0002] The rear panel of the rail car operation control equipment (hereinafter referred to as GYK equipment) on the existing rail car is equivalent to the bridge interface for the interactive connection between the GYK device and other devices on the rail car, and plays a role in the communication between the GYK device and other devices or sensors. to a key role. The air seat of the GYK equipment on the existing rail car or the DMI equipment chassis is connected by the traditional manual welding and wiring process. In order to prevent electromagnetic interference, the tail of each air seat is also covered with a magnetic ring.

Problems solved by technology

The air seat of the GYK equipment on the existing rail car or the DMI equipment chassis is connected by the traditional manual welding and wiring process. In order to prevent electromagnetic interference, the tail of each air seat is also covered with a magnetic ring. The process of welding internal wiring brings great inconvenience in the equipment production stage and later maintenance and inspection, which affects production efficiency, and after delivery to the user, the pins and wiring of the aviation seat are welded on the rail car under long-term vibration and high temperature environment The reliability of the rail car cannot be guaranteed, and the aging or virtual welding of the pins of the aviation seat poses a safety hazard to the operation of the rail car and affects the normal operation and use of the rail car
