Intelligent scribing shaft system

Abstract

The invention discloses an intelligent scribing shaft system. The system comprises a controller; a plurality of decoders; a plurality of relay groups; the input ends of the sockets are connected withthe output end of the relay set, and the output ends of the sockets are connected with a voltage measuring hole, corresponding to one magnetic head, of a VESBA board of an indoor arithmetic unit of the AzS350U axle counting system; and the socket is used for receiving and executing the control signal from the controller so as to output an axis marking signal to the voltage measuring hole. The invention discloses an intelligent scribing shaft system. Operators can directly perform shaft drawing operation in each area without going to the site for shaft drawing, the labor intensity of the operators is reduced to a great extent, the shaft counting fault processing time is shortened, the size and the weight of equipment can be effectively reduced through the circuit design, and compared with atraditional shaft drawing plate, the burden of the operators can be reduced.

Description

technical field [0001] The invention relates to the field of train line maintenance, in particular to an intelligent axle rowing system. Background technique [0002] The AzS350U axle counting system is an important component of the urban rail transit signal system. This device mainly uses the closed-loop sensor installed on the rail to monitor the number of train wheel pairs passing by. When the passing number of wheelsets entering the axle counting section is equal to the passing number of wheelsets leaving the section, the section is considered to be in the clearing state, otherwise it is considered to be in the occupied state. Its function is to detect the position of the train on the track in real time, which is the basis for realizing the interlocking function. [0003] When the AzS350U axle counting system fails or is powered off for maintenance, such as replacing the plate, the corresponding section needs to pass through the faulty section before the section becomes...

AI Technical Summary

Problems solved by technology

[0004] 1. Since each interval is about 2-3 kilometers on average, the operator travels a long distance, and the troubleshooting method takes a long time

Especially when the whole station is operated, the processing time may exceed 2 hours, which seriously affects the related power outage operations, such as the annual inspection of the power screen, UPS, and axle counting cabinets.

[0005] 2. The outdoor track layout and the installation position of the axle counting head are intricate, and the on-site operators are prone to misjudgment of the position and direction, resulting in wrong axles, and need to re-mark the axles, resulting in magnification of faults

[0006] 3. When using the traditional reeling board to operate, it is easy for the reel head to be disturbed again, and it is necessary to return to the previous head to re-mark the reel, which seriously affects the working time

[0007] 4. After the artificial outdoor axles are drawn, the number of axles in the last section is always locked and remains occupied and cannot be cleared. It is necessary to perform a pre-reset and arrange for the train to be degraded and cleared, which will affect the normal operation and service of the subway line.

[0008] 5. The traditional reeling board is wide, rough, heavy, and not easy to carry, and it is very inconvenient to deal with axle counting faults
