Information processing device

Abstract

The purpose is to determine whether the device's emergency stop function is working correctly. [Solution] The information processing device comprises a switch circuit section for emergency stopping of the device, a circuit breaker circuit section for the device, and a control unit. Here, the switch circuit section is connected to the control unit via a command line for monitoring whether or not the switch circuit section is energized. The circuit breaker circuit section is also connected to the control unit via a drive line for monitoring whether or not the circuit breaker circuit section is energized. Furthermore, the switch circuit section and the circuit breaker circuit section are connected via an interlocking switch that operates in conjunction with the emergency stop switch and energizes a drive unit that drives the circuit breaker in the circuit breaker circuit section. The control unit then performs the following actions: obtaining whether or not the switch circuit section is energized via the command line, obtaining whether or not the circuit breaker circuit section is energized via the drive line, and determining whether or not the emergency stop of the device is abnormal based on whether or not the switch circuit section and the circuit breaker circuit section are energized.

Claims

1. The device comprises a switch circuit for emergency stopping, a circuit breaker for the device, and a control unit. The switch circuit is connected to the control unit via a command line for monitoring whether or not the switch circuit is energized. The interruption circuit is connected to the control unit via a drive line for monitoring whether or not the interruption circuit is energized. The switch circuit is configured such that the energization status via the command line changes in response to the operation of the emergency stop switch in the switch circuit. The switch circuit and the circuit breaker circuit operate in conjunction with the emergency stop switch and are connected via an interlocking switch for supplying power to the drive unit that drives the circuit breaker in the circuit breaker circuit. The circuit is configured such that when power is supplied to the drive unit, the current flow status of the circuit breaker circuit via the drive line changes. The control unit, The presence or absence of power flow in the switch circuit is obtained via the command line, To obtain whether or not the circuit breaker is energized via the drive line, The emergency stop of the device is determined to be abnormal or not, depending on whether or not the switch circuit is energized and whether or not the circuit breaker is energized.
