摘要： PURPOSE:To inexpensively obtain high reliability by preparing a mode switching part and a data comparing part, mutually changing the modes of two processing parts with equivalent relation, and even when abnormality is generated, continuing operation without instantaneously interrupting the operation while recovering the abnormality. CONSTITUTION:A mode switching part 28 switches the processing parts 20 at least to three modes; a single mode for driving each processing part 20 only by the self-data, a parallel mode for driving one processing part 20 in co-operation with the other processing part and a slave system mode to be used for restoring a processing system, and a standby mode when necessary based upon information obtained from a self-diagnostic part 21 and a mode comparing part 27. A data comparing part 29 collates the data included in itself with the data of the other processing part 20 replaced by a data link part 25 and outputs the data to be stored in accordance with the current mode of the self- part to a memory 24. Consequently, the continuity of the processing can be maintained even at the time of generating a failure and high reliability can be inexpensively obtained.

摘要： PURPOSE:To prevent a trouble from being generated in the operation of a train when a fault is generated and to smoothly execute interlock control by always monitoring coincidence between a use system and a standby system and momentarily switching the system without a standstill time when the operation is coincident with the time of system switching. CONSTITUTION:In an interlock control system 10 which is the use system, a normality testing part 11 tests the normal operation of the system itself and when the operation is normal, a normal operation signal a2 is always outputted. Simultaneously, in an interlock control system 20 which is the standby system, a normality testing part 20 tests the normal operation of the system itself and when the normal operation is executed, a normal operation signal b2 is always outputted. Here, when abnormality is generated in the control system 10 and the normal operation signal a2 is stopped being outputted from the normality testing part 11, a switch control part 30 concerns the necessity of switching to the interlock control system 20 which is the standby system. According to a judging part 31 of the control part 30, the normality testing par 21 of the control system 20 tests the normal operation of the system itself and when the operation is normal, the normal operation signal b2 is outputted. The coincidence between the system and the other system is tested by a coincidence testing part 23 based on a feedback input and when the systems are coincident, a coincidence signal b3 is outputted. Then, the system is switched to the control system 20.

摘要： PURPOSE: To eliminate a need for a crossing control logic confirming test at each exchange, to reduce a cost, and to improve safety by a method wherein a plurality of crossing control logic are stored and switching to a crossing control logic corresponding to an interlocking logic responding to switching of the railway apparatus switching unit of an electronic interlocking device. CONSTITUTION: A railroad crossing control logic memory means 21 stores a plurality of crossing control logic 21a responding to the interlocking logic memory means 11 of an electronic interlocking device 10, and a crossing control logic mode switching means 23 switches to a plurality of the crossing control logic 21a corresponding to a plurality of rail way apparatus switching interlocking logic 11a responding to switching of a rail way apparatus switching unit. The link means 21 inputs course constituting information and train approach and exit information related to a crossing in the interlocking logic of the electronic interlocking device 10. A logic matching deciding means 24 compares consistency of the interlocking logic mode of the electronic interlocking device 10 with consistency of a self cross control logic mode, and crossing information input means 26 receives signals from crossing control elements B, C, and D to announce approach and exit of a train to the crossing of an object section.

摘要： PURPOSE: To provide an electronic interlocking device capable of practicing exchange work of an interlocking logic without inserting and removing an interlocking logic memory means. CONSTITUTION: An interlocking logic memory means 11 memorizing a plurality of railway apparatus change-over interlocking logics 11a and an interlocking logic mode input means 13 to stimulate input of an interlocking logic mode 12 in accordance with a single track or a double track or in accordance with another railway track change-over unit, to form a mode selection logic value 13a against the input interlocking logic mode 12 and to form a complement mode selection logic value 13b in complementary relation against a specified logic with the mode selection logic value 13a are provided. An interlocking logic mode checking means 15 to check logical complementary relation between the mode selection logic value 13a and the complement mode selection logic value 13b and a railway apparatus control change-over means 16 to select a railway apparatus change-over interlocking logic 11a in accordance with the interlocking logic mode 12 and to stimulate change-over of a railway track or stoppage of the railway track change-over are furnished.
