The utility model relates to the technical field of gate station traffic bridge protection, disclose a gate station traffic bridge guardrail, including first crossbeam, the inside fixedly connected with fixed block of first crossbeam, the inside rotationally connected with screw rod of fixed block, the outer wall fixedly connected with the swivel block of screw rod, the inside of fixed block is equipped with the limit slot, the outer wall screw thread connection has the clamping block of screw rod, the inner wall sliding connection of clamping block is in the inner wall of limit slot, the inner wall of clamping block abuts and has the connecting column, the bottom fixedly connected with water level sensor of connecting column, the inside of first crossbeam is equipped with the through slot, the outer wall of first crossbeam is provided with support subassembly. In the utility model, rotate swivel block and drive screw rod to rotate, through the cooperation between clamping block and connecting column, clamping block locks connecting column, and water level sensor can be installed and fixed, reach integrated water level monitoring function realizes water level overproof automatic alarm, and the effect that its installation maintenance is convenient.

The invention provides a monitoring device based on carrying an automatic accessory, and relates to the technical field of monitoring cameras, the monitoring device comprises a monitoring camera, a group of electromagnets are fixedly installed on the front side of the right end face of a monitoring camera shell, the electromagnets and the monitoring camera are arranged in the same power supply circuit, and the electromagnets are in magnetic attraction cooperation with a magnetic attraction iron attraction plate to attract the monitoring camera; whether the monitoring camera is powered on or not is automatically monitored and judged, when the monitoring camera is powered off due to a fault, the magnetic iron adsorption plate is automatically separated from the electromagnet, and meanwhile, the power supply in the power-off warning shell is switched on, so that automatic alarm of the power-off warning shell with an independent power supply is realized; therefore, a worker is reminded of the power failure of the current monitoring camera in the first time, and the problem that timely warning cannot be realized when the power failure of the existing monitoring equipment occurs due to a fault is solved.

The invention discloses a Wuyi narcissus baking color quality intelligent discrimination method and system based on a near infrared spectrum optimized by a genetic algorithm. The near infrared spectrum of a Wuyi narcissus raw tea sample at the wave band of 400-4000 cm <-1 > is collected, in combination with CIE-Lab chromaticity parameters, Savitzky-Golay smooth filtering and multiple scatter correction combined preprocessing is adopted to eliminate noise interference, key characteristic wavelengths are screened by using a genetic algorithm to construct a wavelength-chromaticity incidence matrix, and the wavelength-chromaticity incidence matrix is used for detecting the wavelength-chromaticity of the Wuyi narcissus raw tea. Partial least squares regression (PLS) and a support vector machine (SVM) are coupled to construct a GA-PLS-SVM hybrid prediction model, and accurate inversion of baking intensity and time parameters is realized. The model calibration set L * / a * / b * prediction R is larger than or equal to 0.90, the verification set R is larger than or equal to 0.85, 82.3% of baking process deviation can be recognized online, and the rock tea standardized production efficiency and the process control precision are remarkably improved.

The application discloses a kind of polymer power battery feeding and discharging anti-collision manipulator, including manipulator installation mechanism, including anti-collision installation plate and spacing adjusting mechanism being set on anti-collision installation plate, spacing adjusting mechanism includes longitudinal drive part and bidirectional screw rod, longitudinal drive part is set on anti-collision installation plate, and its power output end is connected with one end of bidirectional screw rod;Two ball nuts are provided on bidirectional screw rod;Battery grabbing mechanism, two sets in total, symmetrically set below anti-collision installation plate, battery grabbing mechanism includes air claw installation plate, and a column of grabbing manipulator is installed in the bottom of air claw installation plate along transverse direction;And anti-collision mechanism is set on the upper portion of anti-collision installation plate, including connecting plate, anti-collision buffer rod assembly and pressure sensor, pressure sensor is set between connecting plate and anti-collision installation plate, and is electrically connected with alarm system.The beneficial effects of the application are: when battery collision occurs, automatic alarm can be realized, the yield of battery is improved, and the danger of battery fire is prevented.

The invention provides a track structure state monitoring alarm device with autonomous power supply and alarm elimination and a track traffic structure safety state assessment grading alarm method, and the device comprises a detection part which is disposed on the side surface of a track sleeper and is used for transmitting the vibration information of the sleeper; the fixing part is arranged on the foundation and used for fixing the whole structure; the sensing part is arranged on the fixing part, is connected with the detection part and is used for converting the vibration information of the detection part into displacement information; and the alarm part is arranged on the fixing part, is connected with the sensing part, and is used for sending out graded alarms according to the displacement information of the sensing part and reporting the alarms through networking. Therefore, the track structure state monitoring alarm device capable of achieving autonomous power supply alarm elimination can give out graded alarms according to changes of the structure safety state and report the alarms in time, the alarm state can be dynamically adjusted, automatic alarm elimination is achieved, the operation and maintenance efficiency is improved, and the labor cost is reduced.
