The invention discloses a control method, device and system for alarm clock rings, and belongs to the technical application field of wireless communication. The method comprises the steps that the remaining time of remotely-set ringing time is detected; when the remaining time is the set time, obtaining information is sent to an intelligent hand ring, wherein the obtaining information is used for obtaining sleep state information of a user; the sleep state information sent by the intelligent hand ring is received, and the sleep state of the user is determined according to the sleep state information; according to the sleep state, vibration prompt information is sent to the intelligent hand ring, wherein the vibration prompt information is used for indicating the intelligent hand ring to vibrate. According to the control method, device and system for the alarm clock rings, the user is awakened through vibration of the intelligent hand ring; due to the fact that the intelligent hand ring is worn on the wrist of the user, the user can be awakened without too large vibration intensity or too loud ringing sound; the intelligent hand ring will not influence the rest of the other people due to the fact that the intelligent hand ring is worn on the wrist of the specific user; in addition, due to the fact that vibrations with different intensities are adopted according to the sleep state of the user, user experience is better.

The Coriolis mass flow meter of this invention comprises two parallel curved flow tubes 1 and 2, a drive unit 15, and a pair of vibration sensors 16 and 17. An inlet-side manifold 24 dividing the flow of a fluid being measured into the two flow tubes 1 and 2 from the inlet thereof, and an outlet-side manifold 25 joining the fluid flows flowing in the two flow tubes 1 and 2 to discharge from the fluid outlet thereof are mechanically connected to a meter body 30 only at the inlet side of the inlet-side manifold 24 and at the outlet side of the outlet-side manifold 25, respectively. With this arrangement, the effects of vibration transmitted from the meter body 30 and all structures connected thereto can be reduced at the joint parts between the inlet-side and outlet-side manifolds 24 and 25 that serve as vibration fulcrums.

The invention discloses an observational method used for a trench slope gravitational erosion field test. The observational method is characterized in that a DV sight line is perpendicular to structured light rays on an abrupt slope through a geography instrument, and according to video screenshots in the test process, the gravity erosion amount and the waterpower erosion amount, namely the total erosion amount, the gravity erosion amount and the waterpower erosion amount of individual rainfall, in an individual rainfall event, the gravity erosion amount occurring after rainfall is completed, and slope direction distribution and gradient distribution of the abrupt slope at any time can be respectively calculated. The observational method is further characterized in that the definition of laser rays projected on the abrupt slope is strengthened by adjusting indoor light rays, building a rainproof observation room and installing an anti-fog filter, the DV sight line is perpendicular to a laser plane emitted by a geography instrument main machine by adjusting the sight line angles of a DV, and testing and adjustment are carried out according to a sight line calibrator. According to the observational method, the water power erosion amount can be separated from the gravity erosion amount, and the gravity erosion amount in the rainfall process and the gravity erosion amount after rainfall can be quantitatively observed and calculated.
