Description

AUTO-CHECKING SYSTEM FOR THE INTERLOCKING SYSTEM OF RAIL}

The present invention relates to an electronic interlock device automatic inspection system of the railway.

In railways, signal control systems help to operate limited railway resources efficiently and economically and are an essential system for the safe operation of trains. In particular, the interlocking system is an essential device that secures the safe operation of trains as a device that operates each other according to a certain order and rules, such as a signal and a line changer, for smooth train operation in a station.

Referring to the linkage device, the linkage device in the railroad is a device that determines the electrical or mechanical method such as a signal, a line changer, etc. in order to perform smooth train operation in the station.

In the station, many tracks are concentrated and complicated work is required to switch tracks and handle signals according to the direction of arrival, departure and exchange of trains by turnouts. Relying on the operator's attention to confirming the changeover and signal handling of the line diverter may result in mishandling and misunderstandings, resulting in deterioration of efficiency. Therefore, chains and chains are designed to make certain order and rules for handling line changers and signalers, and to keep the chain relations in order. The device for interlocking is called interlocker and the whole device that interlocks with electrical or mechanical is called interlocking device and it is a key device to secure safe driving of train.

The trend of interlocking autonomy is rapidly changing from the existing electrical interlock device to the electronic interlock device, and by implementing the fail-safe principle of the electrical interlock device electronically, the equipment cost is low, the size is small, and the power consumption is low. It has the advantage of easy maintenance and troubleshooting. In addition, in consideration of the safety and reliability peculiar to the electrical interlock device, the electronic pursuit is made.

Mechanical interlocks, electrical interlocks, and electronic interlocks are currently being used. Electrical interlocks are still mainstream, but recently, due to the development of science and technology, the expansion of electronic interlocks has been rapidly developed. The situation is losing. As such, the interlock device has made a significant change by incorporating a semiconductor circuit into an interlock function that has been dependent on relay logic due to the development of microprocessors and computers.

 As is already known, the electro-interlock system is designed by the fail-safe principle of the relay itself, so that the system does not develop into special hazards caused as a result of any failure. However, digital computers can't be designed on a simple basis because there are so many virtual situations that you can't predict what kind of danger will be caused by the failure of one component.

 In addition, due to the recent increase in transportation demand, large-scale station, increase of the number of trains, and the addition of various functions for operation management and maintenance management, the interlock inspection operation and confirmation frequency of the interlocking device increased considerably, resulting in a lot of test time and Human effort is required, resulting in longer production periods and increased costs. In addition, mistakes that occur in the inspection can cause serious accidents in operation, and the inspector has many problems, such as anxiety about not making a mistake.

In this way, the interlock device is a situation in which the transition from the existing relay interlock device to the electronic interlock device is rapidly being made, and by pursuing electronicization, the influence on the electromagnetic environment, such as hardware and software, and the absence of established software verification techniques. It is very difficult to grasp safety, and in case of hardware-related failure, it is difficult to grasp the state and establish countermeasures.In advanced countries, railway developed countries have overcome these weaknesses through long-term trial and error. It is in use. As a result of the recent promotion of electronics in Korea, some of them have been localized and used in the center line, but they are poor in the electromagnetic environment and require continuous supplementation.

 Therefore, in order to operate the train safely and efficiently by linking the track changer, the track circuit, and the signal interlocker, when the linkage system is newly established or changed, the linkage test must be performed to confirm that the chain relationship is secure. However, due to the recent increase in transport demand, the large scale of the station, the increase in the number of trains, and the addition of various functions for operation management and maintenance management have increased the number of handling and confirmation of the interlocking device. As a result, there is a problem of prolonging the manufacturing period and increasing the cost.

In addition, errors in the inspection can cause serious accidents in the operation of the train, it takes a lot of inspection time, there are a lot of mistakes, it is necessary to check again, only those who have a lot of knowledge in the interlock system can test However, there is a problem that can not immediately respond to the interlock change.

The present invention has been made to solve the above problems, and implements the interlocking check control algorithm based on the interlocking table and the various condition tables from the interlocking table using a computer and a hardware device, and automatically performs a complex interlocking test based on this. The purpose of the present invention is to provide an automatic inspection system for electronic linkage of railways.

In order to achieve the above object, an automatic inspection system for an electronic interlock device for a railway according to the present invention, in a system for inspecting a railway interlock device, receives an interlocking diagram for an electronic interlock device for a station to be inspected, and displays an interlock table. Automatically generate and register a database for interlocking inspection, perform interlocking inspection items and receive field results, perform interlocking inspection, determine the suitability according to the interlocking inspection items, and output the test results. Simulates the control target of the interlocking test simulation module to be stored in the base and the electronic interlocking device to be tested by receiving the control state of the field signal from the interlocking test simulation module or the electronic interlocking device and transmitting the changed field state to the electronic interlocking device. It consists of an on-site simulation module to simulate with.

As described above, in the present invention configured, an automatic interlocking inspection device which implements the interlocking inspection control algorithm based on the interlocking table and the various condition tables from the interlocking table and automatically performs a complex interlocking inspection based on the interlocking table and various condition tables, does not require a check by a tester's mistake It can shorten the inspection time, test even those who do not have knowledge of the interlocking system, and have the advantage of responding immediately to the railway line change.

In addition, the present invention performs a faster and more reliable inspection through the scientific and quantitative inspection of the conventional interlocking inspection method, and can minimize the inspector by automatic inspection by computer, as well as factory inspection It can be used in regular interlocking inspections at sites that are regularly conducted. In addition, it is possible to inspect items by item and connect them by using the electronic interlocking device and the connector. Since the inspected data is managed by computer and storage device, it is possible to predict the future change of the electronic interlocking device and contribute to the safe operation by procurement of material and timely repair of the system. In addition, economically, management can be improved by reducing costs and expenses due to the reduction of manpower and inspection time. Since all inspection data is stored by computer, history can be managed by database of inspection values.
