Description

Intelligent management system and safety control method for turnout in non-concentrated area

Technical Field

The invention relates to the technical field of railway technical operation management, relates to the field of non-centralized area turnout production safety, and in particular relates to an intelligent non-centralized area turnout management system and a safety control method.

Background

Railway turnout is a line connection device for transferring rolling stock from one track to another track, and is usually laid in a large number at stations and marshalling stations, and the state and opening direction of the device are critical to railway driving safety and operation safety.

At present, the turnout control is divided into two modes of centralized control and non-centralized control, and for turnout operation and safety monitoring of a centralized area, a computer interlocking system is used for automatic operation and management, and a track circuit is required to be paved and a turnout point machine is required to be installed; the non-centralized control mode is to operate the turnout by manual pulling in the section without the track circuit. The turnout in the non-concentrated area is numerous, is mainly distributed in the line, intermediate station, private line and the inside line of the factory and mine that the traffic is less, because the characteristics such as the work load is little, the position is relatively remote, electrified transformation cost is too high, still remain original manual vertical switch way, guarantee switch running state and opening direction with fixed mode of mechanical padlock and bolt.

The operation flow of the turnout operators is as follows:

1) Opening a mechanical padlock and a bolt of a lifting concave clamping groove opening on a manual vertical turnout trigger;

2) Lifting a turnout spanner plate fixed in a lifting clamping groove of a fixed table from bottom to top, penetrating the lifting clamping groove to the upper part of the clamping groove, rotating the turnout spanner to the other side to the upper part of the other lifting clamping groove, at the moment, pulling a turnout switch rail to the other side through the turnout spanner to change the track, then putting down the turnout spanner from the upper part of the other lifting clamping groove, penetrating the clamping groove from top to bottom, and parking in the clamping groove;

3) And (3) locking the bolt of the other lifting clamping groove to be closed, and locking the turnout spanner in the other lifting clamping groove to finish the operation.

The turnout in the non-concentrated area has no track circuit and automatic control equipment, so that a shunting person is required to pull the turnout and report information on site, and the original operation mode brings two problems, namely the turnout is in a non-control state for a long time, and the turnout opening direction, the turnout locking state, the turnout close condition and the like cannot be controlled; secondly, the conditions of destruction of social personnel and human misoperation exist, and effective supervision is difficult. Which is essentially caused by the asymmetry of the switch state information. The safety management of the existing manual turnout mainly has the following hidden trouble:

A. The mechanical padlock is too simple and is easy to break, so that the turnout spanner is operated by illegal personnel;

B. because of manual operation, and multiple persons have mechanical keys, the identity and authority of operators cannot be identified, and whether the operation is standard or not is judged, for example, people do not pull to a specified stock way, forget to insert pins or forget to close locks;

C. the operation cannot be automatically recorded, and the accident cause and responsibility cannot be analyzed and determined;

D. the full close contact between the stock rail and the point rail cannot be ensured, for example, a manual wrench cannot change the track in place, the wrench is loose, and foreign matters exist between the rails;

E. when the turnout area is occupied by a vehicle, the turnout cannot be pulled any more, but the existing mechanism cannot be controlled; the hidden danger is likely to cause accidents such as derailment and the like, and directly affects the safety of the manual turnout;

F. since manual operations may be misdirected, resulting in inconsistent hook planning, there are no precautions other than manual field checks.

The problem of asymmetric turnout state information in a non-centralized area is solved, and the method can be divided into two ways of centralized transformation and Internet of things technology in principle. The centralized transformation of the turnout in the non-concentrated area needs to lay a track circuit, provide a power supply, install a turnout turning machine, install a computer interlocking system and related equipment, and has extremely low input-output ratio. The method adopts the Internet of things mode, monitors key parts and operation actions of the turnout by utilizing the Internet of things technology, and realizes information symmetry by uploading data in real time. With the rapid development of the Internet of things technology, the foundation for solving the problem of switch safety protection in non-concentrated areas at low cost is provided. Therefore, the Internet of things technology is used as a core, the electronic lock, the sensor and other equipment technologies are integrated, and the intelligent safety protection system for the turnout in the non-concentrated area is researched and developed, so that the intelligent safety protection system has great practical significance for the safety protection of the non-concentrated area.

The intelligent safety management method for the railway turnout utilizes the Internet of things to manage the safety of the railway turnout, can perform intelligent safety management on the operation of the railway turnout, and has the following characteristics: the manager can carry out intelligent safety information system management on the railway turnout through the system, so that potential safety hazards can be effectively reduced, accidents are prevented, and resource sharing is fully realized; the real-time position and safety management of the railway turnout can be determined; the health monitoring history record and the big data analysis judgment and management system can be established; and the internal faults, insufficient power and the like of the module (including temperature, 3D acceleration, pressure and other digital sensors, MCU, communication chip, lithium battery power supply and the like) are managed in real time.

However, the safety management control method cannot perform safety management control such as operator authentication on the turnout wrench, and cannot perform early warning on abnormal conditions of a turnout area, such as the situations that the wrench is not pulled to a correct position according to a plan, is not closely attached, has locomotive turnout and the like, and has supervision flaws for improving the working and management efficiency of a railway transportation management center and improving the safety guarantee of railway transportation.
