Abstract
An atmospheric environment monitoring apparatus includes: a communication interface unit which sequentially receives first atmospheric environment measurement data to N-th atmospheric environment measurement data from any one atmospheric environment sensor when a measurement period of an atmospheric environment sensor comes; a data storage unit which stores the first atmospheric environment measurement data to the N-th (N is an integer of 1 or more) atmospheric environment measurement data; and a control unit which checks the total number of the first atmospheric environment measurement data to the N-th atmospheric environment measurement data.
Claims12
An atmospheric environment monitoring apparatus comprising:
- a communication interface unit which sequentially receives first atmospheric environment measurement data to N-th atmospheric environment measurement data from any one atmospheric environment sensor when a measurement period of an atmospheric environment sensor comes;
- a data storage unit which stores the first atmospheric environment measurement data to the N-th (N is an integer of 1 or more) atmospheric environment measurement data;
- and
- a control unit which checks the total number of the first atmospheric environment measurement data to the N-th atmospheric environment measurement data, primarily determines that failure occurred in the atmospheric environment sensor when the total number is equal to or less than M (M is an integer of 2 or more), checks the number of abnormal atmospheric environment measurement data which are atmospheric environment measurement data including an abnormal atmospheric environment measurement value of the first atmospheric environment measurement to the N-th atmospheric environment measurement data when the total number is more than M, and secondarily determines that failure occurred in the atmospheric environment sensor even when the number of abnormal atmospheric environment measurement data is equal to or more than a predetermined number.
An atmospheric environment monitoring apparatus comprising:
- a communication interface unit which periodically receives first atmospheric environment measurement data to N-th atmospheric environment measurement data from a first atmospheric environment sensor to an N-th atmospheric environment sensor;
- a data storage unit which cumulates and stores the first atmospheric environment measurement data to the N-th atmospheric environment measurement data periodically received from the first atmospheric environment sensor to the N-th atmospheric environment sensor by the communication interface unit;
- and
- a control unit which classifies the first atmospheric environment measurement data to the N-th atmospheric environment measurement data into a first correlation data group to an L-th correlation data group, determines data validity for each of the first correlation data group to the L-th correlation data group, and determines that failure occurred in one or more atmospheric environment sensors of the first atmospheric environment sensor to the N-th atmospheric environment sensor when there are one or more invalid correlation data groups of the first correlation data group to the L-th correlation data group.
A method for detecting failure of an atmospheric environment sensor in an atmospheric environment monitoring apparatus, comprising:
- a data reception step of periodically receiving first atmospheric environment measurement data to N-th atmospheric environment measurement data from a first atmospheric environment sensor to an N-th atmospheric environment sensor;
- a data classification step of classifying the first atmospheric environment measurement data to the N-th atmospheric environment measurement data into a first correlation data group to an L-th correlation data group in accordance with correlation to each other;
- a validity determination step of determining data validity for each of the first correlation data group to the L-th correlation data group;
- and
- a sensor failure detection step of determining that failure occurred in one or more atmospheric environment sensors of the first atmospheric environment sensor to the N-th atmospheric environment sensor when there are one or more invalid correlation data groups of the first correlation data group to the L-th correlation data group, as a result of determination of data validity for each of the first correlation data group to the L-th correlation data group.
