Moreover, the collation information in Patent Document 2 is information only showing the collation results in each system, so in order to verify that no communication error has occurred for the control data on the communication path, for example, it is described that "for the control data, in order to ensure a high level of communication Content, the control data itself needs to be multiplexed and sent" (JP 2004-302708, paragraph [0037]), it is necessary to adopt a multiplexed configuration

Embodiment 1

[0049] In this embodiment, as a multi-system information processing system, an interlocking device 1 including three computing units is assumed. In addition, it is assumed that the linkage device 1 is connected to the signal control device 2 through the network 4 , and the signal control device 2 is connected to the signal device 3 . In addition, the present invention may also be composed of a double system based on the 1-series and 2-series, or a multiple system of 3 or more lines. In addition, the multi-system information processing system to which the present invention is applied is not limited to signaling equipment in railways, and can be applied to various equipment by reading the signal control device 2 and the signaling equipment 3 as output control devices and control target equipment, respectively. Likewise, the interlocking device 1 can be read as a data generating device that generates control data for controlling the controlled device from input data. Moreover, t...

Embodiment 2

[0081] In this embodiment, it is described that the transmitting unit 411 in the interlocking device 1 generates an error detection code data 402 based on the data calculated by the code generating units (13, 23, and 33) of each system, and converts the control data 101 and the formed error The detection code data 402 is sent to an instance of the signal control device 2 . Figure 5 It is the structure in Example 2. The interlocking device 1, the signal control device 2, the signaling device 3, the network 4, and the transmission message 5 correspond to those of the first embodiment, and have the same configuration unless otherwise specified.

[0082] As a method of constructing verifiable one code data from code data received from a plurality of departments, for example, secret function distribution can be applied. The so-called secret function distribution is a method of performing distributed encoding of a secret function on a plurality of systems (i), and is as follows: I...

Embodiment 3

[0088] In this embodiment, an example in which the code pre-verification unit 42 is provided in the interlocking device 1 is shown. Figure 6 This configuration is shown in . The interlocking device 1, the signal control device 2, the signaling device 3, the network 4, and the transmission message 5 correspond to those of the first embodiment, unless otherwise specified, they have the same configuration.

[0089] Before the control data 101 is transmitted to the signal control device 2 , the code verification is performed by the code pre-verification unit 42 , thereby preventing erroneous control data 101 from flowing out of the interlocking device 1 . According to this, compared with Example 1, abnormality of the control data 101 can be detected earlier, and it becomes possible to pinpoint, eliminate, and maintain the cause. In addition, since the interlock device 1 can verify the control data, according to the configuration of this embodiment, the transmitter reduces the fa...

Abstract

The present invention provides a multiplex information processing system including at least two processing units configured to generate control data for controlling a control target apparatus on the basis of input data, the multiplex information processing system including a processing unit of a first system configured to output control data of the first system generated on the basis of the input data, a processing unit of a second system configured to output code data of a second system encoded with an encoding algorithm peculiar to the second system with respect to control data of the second system generated on the basis of the input data, and a control unit configured to receive the control data of the first system and the code data of the second system and determine, on the basis of verification results of validity of the control data of the first system and the code data of the second system, propriety of transmission of the control data of the first system to the control target apparatus.

Description

technical field [0001] The present invention relates to an information processing system, an output control device, and a data generating device, and more particularly to a fail-safe system that performs multi-system processing on input data. Background technique [0002] Guaranteeing fail-safety is important in systems where guaranteeing safety is strongly desired. For example, in a railway signal security device, in order to ensure the safety of train operation, it is necessary to safely control the train regardless of any failure of the equipment constituting the signal security device. This property is called fail-safety, and in the case of a signal having fail-safety, it is configured to stop the aspect (aspect) or perform blackout (brownout) when the signal fails. [0003] The idea of ​​this fail-safe is used in various fields including automobiles. For example, in the field of railways, signal relays are used as switches to control signal transmission, and the fail-...
