The invention provides a power source apparatus and a vehicle with the same, capable of furthermore miniaturizing an outer case of the power source apparatus. The power source apparatus is provided with battery blocks 50 made up of a plurality of battery cells 1 connected in battery stacks, and an outer case that holds the battery blocks 50. A block circuit board 60 to control the battery cells 1 that make up each battery stack and electrical components 63 connected to the block circuit board 60 or the battery stack are disposed in the end-planes of each battery stack. With this arrangement, electrical components are disposed in each battery block eliminating the need for a special purpose electrical component case and allowing outer case enlargement to be avoided.

The invention relates to an extracting device which comprises a cylinder body, a piston, a pull rod, a buffer matter supply unit and a buffer unit, wherein the cylinder body comprises a hollow cavity which is provided with a first opening at the tail end of the cylinder body and a second opening that is positioned at the front end of the cylinder body and is communicated with the hollow cavity; the piston is positioned into the hollow cavity, the edge of the piston contacts with the wall of the hollow cavity and divides the hollow cavity into a first region and a second region, the first region is positioned between the piston and the front end of the cylinder body, the second region is positioned between the piston and the first opening; the pull rod is connected to the piston and moves the piston; the buffer matter supply unit provides a buffer matter to the second region so as to inhibit impurities from entering the first region; the buffer unit enables the second region to form a closed space and to collect the buffer matter; when the piston moves towards the tail end of the cylinder body, a material is extracted to the first region through the second opening, and the buffer matter is discharged into the buffer unit.

The invention provides an automatic chip alignment device and an alignment method, which belong to the technical field of laser chip detection equipment. The chip automatic alignment device includes: a moving mechanism; an alignment piece, and the alignment piece has a correction plate; The first hole body is suitable for the chip to pass through, and a group of opposite sides of the first hole body is provided with avoidance grooves. The chip automatic alignment device provided by the present invention drives the alignment member to move forward, backward, left, and right in the first direction and the second direction by controlling the moving mechanism. The chip is adjusted in angle and position under the action of the side of the first hole, and an avoidance groove is provided on the first hole, and the avoidance groove can prevent the light-emitting point on the chip from touching the side of the first hole. Ensure that the chip is in an accurate position and angle during detection, avoid the phenomenon that the detection mechanism cannot accurately detect the corresponding position on the chip, and ensure the accuracy of the chip detection result.

The invention relates to the technical field of chip testing, in particular to a chip testing device and a testing method based on a double integrating sphere. Including: an automatic supply device, an automatic alignment device, a test device and a storage device arranged in sequence along the chip transmission direction; the test device includes: a turntable with at least two test stations set opposite to each other; a driving structure arranged on one side of the turntable , including a bracket, a drive piece connected to the bracket, and a slide rail slidably connected to the bracket, and two installation stations are arranged side by side on the bracket; the first integrating sphere and the second integrating sphere are respectively arranged on the two installation stations. Under the action of the driving member, the first integrating sphere or the second integrating sphere is aligned with the test station between the two installation stations, and the maximum testable power of the first integrating sphere and the second integrating sphere are different. The chip testing equipment and testing method based on double integrating spheres provided by the invention can simultaneously measure chips with different powers and wavelengths, and the testing efficiency is high.

The invention relates to the technical field of nuclear power plant digital alarm design, and specifically discloses a nuclear power plant digital alarm grading and partitioning method. The method includes: 1. Carrying out classification and division of the alarm trigger signal of the nuclear power plant; 2. Obtaining the alarm trigger signal; 3. Using the alarm trigger signal to trigger the third-level alarm interface; 4. Using the third-level alarm signal to The second-level alarm interface is triggered; 5. Use the second-level alarm signal to trigger the first-level alarm interface; during normal operation, the operator can view the latest alarm through the latest alarm area and take corresponding actions. Corrective measures; when a large number of alarms occur under transient conditions, the operator can quickly locate and give priority to important key alarms through key function partitions or system partitions, so as to make accurate judgments and avoid unit state deterioration; at the same time, the alarm Displayed on the big screen in the main control room, it is intuitive and eye-catching.

The invention discloses an audio signal based wind power blade damage monitoring method and monitoring system. Audio signals sent by blades of wind driven generators in a wind power plant are circularly collected in the operation process, characteristic values of the audio signals are calculated, change of each unit audio signal characteristic value is analyzed, change of blade states is judged according to the change condition of the characteristic values, and a warning signal is sent for possible damage to remind a worker to perform further check, so that damage and defect of the blades are timely found in the early occurrence and development period, repairing measures are taken, the operation quality of the blades is improved, and meanwhile, major accidents such as blade breaking and falling and the like are prevented. The monitoring system comprises an omnidirectional microphone, a directional microphone, a collection amplification circuit, a conditioning circuit, an A / D conversion circuit, a connector, a data acquisition card and a computer. The monitoring system takes the irreversibility of blade damage as work foundation, so that the result is accurate, and the reliability is high.
