Size-lengthened transponder with segmented structure

Abstract

The invention discloses a size-lengthened transponder of a segmented structure, and the transponder comprises a circuit board, a receiving antenna and a transmitting antenna; the transmitting antenna is arranged on the outer side of the receiving antenna and arranged along the peripheral edge of the circuit board, the circuit board is divided into a first PCB, a second PCB and a third PCB, and the receiving antenna and the transmitting antenna are also divided into three parts, which are arranged on the three corresponding PCBs in a segmented manner; an energy conversion circuit, an oscillation sending circuit, a message processing circuit, a message storage circuit and a message rewriting circuit are arranged on the second PCB, a receiving antenna on the second PCB is connected with the energy conversion circuit, and the message processing circuit is connected with the oscillation sending circuit, the message storage circuit and the message rewriting circuit; a transmitting antenna on the second PCB is connected with the oscillation transmitting circuit; the three parts of receiving antennas and transmitting antennas distributed on different PCBs are connected through wires to form a complete rectangular receiving antenna and a complete rectangular transmitting antenna.

Description

technical field [0001] The invention belongs to the technical field of railway communication signal transmission, and relates to a section-structured size-extended transponder. Background technique [0002] The transponder is an important equipment in the field of railway communication signals. It is laid in the middle of the train track. When the train passes above the transponder, it communicates wirelessly with it. The transponder adopts the principle of electromagnetic coupling to receive the energy emitted by the train's on-board antenna, convert it into electrical energy and then convert it into electrical energy. Its own message information is sent back to the on-board equipment wirelessly to realize the communication between the ground and the train. At present, the general design scheme of the transponder is: the interior is a PCB circuit board, on which are arranged receiving and transmitting antennas and various circuit function modules, and the exterior is the eq...

AI Technical Summary

Problems solved by technology

Due to the increase in the size of the transponder PCB circuit board, the following problems will be caused: 1. It exceeds the size requirements of ordinary PCB circuit board manufacturers; 2. It is impossible to use ordinary reflow soldering machines and wave soldering machines for component welding, Only manual welding can be used, which affects product production efficiency and production quality; 3. PCB circuit boards are easily bent and damaged during the turnover process

Due to the above reasons, it causes a lot of inconvenience in the process of producing, processing and debugging the transponder
