Abstract
In the disclosure, unnecessary notification is suppressed in notification that indicates abnormality of an analog signal. A signal processing device includes: a signal state determination part, which determines, for an analog input signal, whether an abnormal state lasts longer than a predetermined time; a notification signal generation part, which notifies, based on the determination result, a controller that an abnormal state occurs in the analog input signal.
Claims15
A signal processing device, which processes an analog input signal from a sensor and delivers the signal to a control device, comprising:
- a signal state determination part, which determines, for the analog input signal, whether an over-range or under-range state lasts longer than a predetermined time;
- and
- a notification part, which notifies the control device that the over-range or under-range state occurs when the signal state determination part determines that the state lasts longer than the predetermined time.
A control method of a signal processing device, which processes an analog input signal from a sensor and delivers the signal to a control device, the control method comprises:
- a signal state determination step, which determines, for the analog input signal, whether an over-range or under-range state lasts longer than a predetermined time;
- and
- a notification step, which notifies the control device that the over-range or under-range state occurs when it is determined in the signal state determination step that the state lasts longer than the predetermined time.
