The indicating device is connected with the latch register; the latch register is connected with the signal converter; the signal converter is connected with the SATA interface; the signal converter receives the serial data from a board to be tested through the SATA interface and then converts the serial data into the parallel data for the latch register to implement the data read-in check; after the check, the data is converted into the serial signal through the signal converter and the serial signal is output through the SATA interface to the SATA to be tested for data read-out check through the inner procedure of the board to be tested; the indicating device indicates whether or not the SATA interface on the board to be tested is good according to the check result. The invention also discloses an SATA interface testing method. The device and the method need no hard disc when testing the function of the SATA interface of the mainboard, thus not affecting the testing result due to the vibration of the hard disc and reducing the testing cost.

The invention discloses a vibration test device for an automobile engine sealing gasket, which comprises an engine cylinder head and an engine cylinder block. A gasket is connected between the engine cylinder head and the engine cylinder body. Gasket real-time misalignment detection device, the automobile engine gasket vibration test device, by installing a detection device in the engine cylinder head to detect the position of the gasket, the trigger device of the device will generate power to the contact detection mechanism Drive, so that the end of the rocking rod is easy to shake and continuously touch the position of the edge of the inner hole of the gasket, and the electric signal feedback is generated through the resistor sheet, so as to determine the displacement of the gasket in real time, and because the trigger mechanism and the contact mechanism are not directly Contact, so there will not be a large force on the gasket, which will affect the experimental results.

The invention relates to an overhauling line of a water supply and drainage system.
