Abstract-An instrument awakened by means of vibration for sin gle hydraulic prop pressure measuring is described in this paper. The principle and implementation of this method are introduced in detail. The instrument uses the high-performance single chip C8051F310 as its MCU and vibration sensor as i ts awaking device. It has such advantages as small volume and low power consumpt ion, and moreover it could resolve the problem that traditional pressure measuri ng instrument on single hydraulic prop can′t be used in coal mine.
Key words-single hydraulic prop; vibration sensor; low power consumption; pressure measuring instrument
