Document Type and Number:
Japanese Patent JPH0658307
Kind Code:
B2
Abstract:
PURPOSE:To detect an abnormal odor by providing plural gas sensors for different kinds of gas to be detected loaded on a moving device. CONSTITUTION:An operator operates an operating device 6, and moves a moving device 1 loaded with a gas sensor 2 along an object inspection route by a remote control or an automatic control. The moving device 1 is constituted of a motor 11 for driving, an encoder 12 for detecting a position,and a driving controller 13, receives a command from a control system 4 through communication equipments 31, 32 and moves through a prescribed inspection route. In this state, a little gas corresponding to an odor generated at the tie of abnormality of a plant is detected by plural gas sensors 211-21N for different kinds of gas to be detected, comparators 421-42N compare the gas with a gas reference value at a normal time and whether abnormality exists or not is decided by a deciding circuit 45, and in case of abnormality, a signal is displayed 5. In such a way, gas corresponding to a little odor generated at the time of abnormality of the plant can be detected, and abnormality of the plant can be detected in its slight stage.
