The invention discloses a terahertz-based rapid security inspection instrument, which includes a workbench and a transmission frame. A number of rollers are arranged between the workbenches. Pushing the spring makes the first blocking lever rotate clockwise around the first rotating shaft, and at the same time pushes the second blocking lever through the intermediate rod, so that the second blocking lever rotates counterclockwise around the second rotating shaft, and the first blocking lever and the second blocking lever move to Inside the middle box, the box body is driven by the conveyor belt through the middle box to complete the security inspection work. The setting of the spring acts as a buffer, and the box body will collide with the pulley on the first stop bar driven by the conveyor belt to avoid damage to the Hydraulic cylinder, the box body will slip between the conveyor belt after being blocked by the first stop bar, so that the box body stops moving for security inspection. When the first stop bar is damaged, the second stop bar can play a backup role, making the device keep running.

The invention relates to a radio-frequency autonomous relative attitude measurement system applied between cluster objects. The system comprises two sets of relative attitude measurement devices with identical structures. Each set of devices include two transmitting antennas, three receiving antennas, two radio-frequency transmitting channels, three radio-frequency receiving channels, an auxiliary radio-frequency receiving channel, two dual-mode auxiliary radio-frequency channels, a baseband processing module, and a high-stability time-based module. The two sets of relative attitude measurement devices respectively receive and sending ranging signals, so that relative attitude measurement of a master member and a slave member can be completed without the need to use observation data provided by other cluster members. Therefore, when parts of members in the target cluster become valid, the relative attitude measurement function can still be provided normally. In addition, with the system, the real-time performance of whole-cycle calculation as well as the real-time performance and operation flexibility of the equipment can be improved.

The invention relates to a decision-making method for optimizing thermal power unit combination under complementation of wind power and an energy storage system. The decision-making method comprises a process of optimizing an upper layer problem and a lower layer problem, wherein the upper layer problem builds upper layer problem constraint conditions by taking minimization of the operating cost of a thermal power unit within a set period as an objective function; the lower layer problem builds lower layer problem constraint conditions by taking maximization of profit acquired by the energy storage system in performing space-time translation and backup supply on electric energy in a power grid as an objective function; and a solution is acquired by using a mode of alternative iteration of the upper layer problem and the lower layer problem. The energy storage system in the model not only can participate in an expected power balance constraint, but also can play a role of backup through complementation with the wind power, and has an ability of directly eliminating the uncertainty; frequent startup and shutdown of the thermal power unit is avoided on the basis of improving the uncertainty acceptance ability; and a regulating effect of the frequency of an electric power system is considered in decision making, so that the decision is enabled to be free from conservation and more conform to the reality.

The present invention relates to an FTL power-down test method, system, device and storage medium. By dividing the FTL into a data overwriting area for writing logic data and an information recording area for writing characteristic data, the information is recorded The area is divided into two sub-areas, and the characteristic data, data address and data length generated each time are accumulated and alternately written into the two sub-intervals of the information recording area to play a backup role. In the two sub-intervals, select the sub-interval in which data was written last time, and use the characteristic data, data address and data length of the sub-interval as the verification data, so that only the data written during power-off is lost during the verification, effectively improving the Verify the integrity of data, improve the security of key data, and improve test efficiency.
