Abstract
The invention relates to a multi-point inclinometer probe tube control short section. By judging whether the inclinometer probe tube is in a vibration state, a battery is controlled to supply electricity to the inclinometer probe tube or not; when judging that the inclinometer probe tube is in a vibration state, a battery tube cuts off power to the inclinometer probe tube which does not work; when judging that the inclinometer probe tube is in a static state, the battery tube supplies power to the inclinometer probe tube which then works and acquires data normally. In judgment of the vibration of the inclinometer probe tube, an appropriate acceleration sensor is used for accurately judging whether the inclinometer probe tube is in a state for acquiring effective data. A clock circuit is used for accurately recording the data acquisition starting time and a memory is used for storing data and the data acquisition starting time. When in use, on the basis of the existing inclinometer, the invention adds the short section which is connected between the inclinometer probe tube and the battery tube used for supplying electricity to the inclinometer probe tube. When not in use, the invention is removed and does not affect the normal use of other functions of the inclinometer.
