Abstract

The invention relates to a control unit for a train running monitoring vehicle-mounted system. A two-out-of-three safety redundancy technique is adopted for controlling the output. The control unit comprises a three-mould collecting module and a three-mould master control unit connected with the three-mould collecting module, wherein the three-mould collecting module comprises a three-mould switching value collecting unit and a three-mould speed collecting unit; the three-mould master control unit comprises three input units which are communicated with each other; the three-mould master control unit is used for sending processed input information into the control unit; the three pieces of input information is voted by the control unit; after the two-out-of-three vote, a vote result is outputted. According to the technical scheme provided by the invention, the control unit in three moulds and the input units are identical to each other and the input signal sources of the input units are the same; the time consistency for collecting data of the three moulds is ensured; the correctness of the data information before three-mould calculation (data exchange before calculation and two-out-of-three vote) is ensured; the correctness of an outputted instruction is ensured.

Description

technical field [0001] The invention relates to a vehicle-mounted control unit of a train running monitoring and recording device (LKJ). Background technique [0002] As the main monitoring equipment for domestic locomotives, the train operation monitoring and recording device (hereinafter referred to as LKJ) has been promoted and used throughout the railway, and has played a significant role in ensuring the safety of railway transportation and promoting locomotive safety management. LKJ adopts the method of on-board storage of line parameters. This storage method requires that on-board data should be maintained and updated with changes in train line facilities, that is, to maintain on-board data storage. Currently, when maintaining system programs and data, it is necessary to To disassemble the device, each data maintenance will cause a lot of waste of manpower and material resources. In recent years, factors such as the construction of new railway lines, the transformatio...
