The dynamic compression device comprises a connecting rod transmission mechanism and a dynamic compression bin body (20); and the rock sample test bin comprises a pressure head (1), a sample bin body (21), a rubber bush (8) arranged in the sample bin body (21), and a pedestal (10) provided with a central hydraulic pressure hole. The test system makes a rock sample 5 simultaneously bear axial static load and hydraulic circulating load, and the active forces transmitted to the rock sample 5 from bearing parts belong to uniformly distributed load according to the Saint-Venant principle, so concentration and non-uniformity of the stress of an action end surface are avoided. Increase of the axial static load makes the rock sample be gradually destroyed in order to obtain the hydraulic triaxial strength of the rock. The test system has the advantages of obtaining of the trixial strength of the rock under high frequency action, good stability and reliability in the test result, low cost of the test process, and small destroys to devices.

InactiveCN109878330APrevent drunk drivingProtect life and property safetyVehicle seatsBelt control systemsMicrocontrollerMicrocomputer
The invention discloses an intelligent anti-drunk driving control system. The system includes a single chip microcomputer. The single chip microcomputer is electrically connected to an igniter turn-onrelay, a vehicle door switch, a key switch, an alcohol signal switch, an alarm output relay, a manual switch, a seat switch, a seat pressure sensor and a safety belt tension sensor. The igniter turn-on relay is electrically connected to an igniting key. The alarm output relay is electrically connected to a buzzer switch and an alarm. The buzzer switch is electrically connected to a buzzer. The manual switch is electrically connected to an alcohol detector. The seat switch is electrically connected to a camera. The camera is electrically connected to the single chip microcomputer. The intelligent anti-drunk driving control system can automatically detect whether a driver drunk-drives or not, can prompt drunk driving behavior through the buzzer, and can effectively prevent the driver from drunk driving, thereby reducing unnecessary traffic accident, protecting the safety of lift and property of others and protecting the driver.
