This invention provides an automated testing device for UAV data links, including an industrial control computer, a display, a spectrum analyzer, a programmable DC power source, a programmable adjustable attenuator, a fixed attenuator I, a fixed attenuator II, a power divider I, a power divider II, an RF switch, a shielded box I, and a shielded box II. The software of the industrial control computer includes a system management module and an automated testing module. The advantages of this invention are: it uses general-purpose testing equipment, is based on a computer-automated program, and controls the settings of each testing device via a bus to simulate remote control, telemetry, image data transmission and reception, and bit error rate statistics; it achieves automated testing of core functional performance indicators of UAV data links such as power consumption, transmit power, spectrum, functionality, receiver sensitivity, bit error rate, and latency.

The utility model discloses an automatic performance parameter testing device for a central gulp valve of a mixed-flow water turbine. A servo electric cylinder is fixed on a bottom plate, and a tension sensor is fixed at the upper end of a telescopic rod through an upper disc and a lower disc; the electromagnet is fixed on the tension sensor through the magnetic isolation upper disc and the magnetic isolation bottom disc; the laser distance measuring sensor is fixed on the inner wall of the supporting cylinder through a support and a support, the proximity switch is fixed on the edge of the magnetism isolating upper disc, and the magnet sucker is fixed below the valve disc. The servo electric cylinder, the laser distance measuring sensor, the tension sensor, the proximity switch and the electromagnet penetrate through a wire passing hole through a control cable with a spiral telescopic joint and are connected into a control box with a digital display panel and a power cable. And the gulp valve is fixed on the supporting cylinder through a valve seat. The technical scheme disclosed by the utility model can be widely applied to the field of mixed-flow water turbine center gulp valve parameter and performance testing.
