Description
Technical Field
The utility model relates to a train line maintenance field especially relates to an intelligence system of marking axle.
Background
The AzS350U axle counting system is an important component device of an urban rail transit signal system, and the device mainly monitors the passing number of train wheel pairs by using a closed-loop sensor arranged on a steel rail. When the number of wheel pair passes entering the axle counting section is equal to that of wheel pair passes leaving the section, the section is considered to be in a clear state, otherwise, the section is considered to be in an occupied state. The function of the interlocking device is to detect the position of a train on a track in real time and is the basis for realizing the interlocking function.
When the AzS350U axle counting system is out of order or is out of power for maintenance, such as plate replacement, then the corresponding section needs the train to pass through the failure section, and the section can be changed to the out-of-clear state. If one magnetic head fails, two sections will be affected, and the train needs to pass through the three magnetic heads forming the two sections to finish clearing. This train operation can be replaced by an operator's split-axle operation, which requires the operator to go outdoors to use a split-axle plate to split off the faulty section one by one, but the existing split-axle operation has the following disadvantages:
1. because each interval is about 2-3 kilometers on average, the walking distance of operators is long, and the time consumption of the fault processing method is long. Especially, when the total station is operated, the processing time may exceed 2 hours, and the time of relevant power failure operation, such as annual inspection of a power supply screen, a UPS and a shaft counting cabinet, is seriously influenced.
2. The outdoor track layout and the mounting position of the axle counting magnetic head are complicated, and field operators are easy to have position and direction judgment errors, so that axle marking errors are caused, and the axle marking needs to be carried out again, so that the fault is enlarged.
3. When the traditional axis marking plate is used for operation, the axis marking magnetic head is easily interfered again, and the magnetic head needs to return to the previous magnetic head for marking the axis again, so that the operation time is seriously influenced.
4. After the shaft is manually scratched outdoors, the number of shafts in the last section is always locked, the occupied state is kept, and the train cannot be cleared.
5. The traditional axle marking plate is wide, rough and heavy, is not easy to carry, and is very inconvenient to handle axle counting faults.
