Title:
燃焼制御装置および燃焼システム
Document Type and Number:
Japanese Patent JP6383310
Kind Code:
B2
Abstract:
A determination precision of an abnormality detection element such as an interlock is improved using a combustion controlling device that includes an output circuit that supplies a binary output signal to one contact of an abnormality detection element, an input circuit that generates a binary input signal corresponding to a signal output from another contact of the abnormality detection element, a sampling portion that samples the input signal within a first period and a second period in which the output signal is respectively a first logic level and a second logic level, an abnormality detection element state determining portion that determines the state of the object to be monitored on the basis of a sampling result in the first period, and a circuit failure determining portion that determines whether a failure occurs in the output circuit and the input circuit on the basis of a sampling result in the second period.
