The invention provides a method for recovering data in a distributed file system and an electronic device. A main PG obtains a data recovery task; at least one first auxiliary PG having data recovery capability and a second auxiliary PG needing to recover data are determined from all auxiliary PGs corresponding to the main PG; a first target PG is determined from the main PG and the at least one first auxiliary PG; and the first target PG is controlled to recover a file copy corresponding to the second auxiliary PG. According to the invention, data recovery of the file copy can be carried out depending on the auxiliary PG, the file copy needing to be recovered can be recovered with no need of all depending on the main PG, and therefore the workload of the main PG is reduced, the IO processing speed of the main PG is not influenced, and the IP processing capability of the cluster is improved.

The lightning arrester inspection transport line of the invention has simple structure and reasonable design; it can not only reduce the cost of production and the labor burden of workers, but also avoid the occurrence of missed inspection and the inflow of unqualified products into the market.

The invention discloses an entrance and exit control system and method that meet evacuation requirements. The system includes a locking device for turning on and off the electric lock, a locking device for turning on and off the electric lock, an entrance and exit controller, a reading device and / or a request to leave device; the locking device for power-on lock and power-off is installed on the door leaf and the door frame, forming a locking point between the door leaf and the door frame; The mechanical lock cooperates to form another locking point of the door leaf and the door frame; the locking device of the power-on lock is connected to the lock power supply through the normally closed output contact of the relay of the entrance and exit controller; the locking device of the power-on and power-off electric lock The normally open output contact of the relay of the entrance / exit controller is connected to the power supply of the lock; the reading device and / or the device for requesting to leave is connected to the entrance / exit controller. The invention can improve the anti-technical opening ability of the entrance and exit, and can effectively improve the safety protection ability under the premise of meeting the requirements of safe evacuation.

The invention discloses a method and a system for transmitting and receiving a data signal of a site / an access point in a wireless local area network, which can maintain the high throughput of a communication link in the wireless local area network in the situation that the dynamic range of the power of a radio signal is wide. The main scheme comprises the following steps: A, presetting a plurality of gains, which can ensure a receiver to work stably, for a digital AGC loop; B, selecting a corresponding preset gain and performing fine-tuning on the corresponding preset gain when necessary according to the intensity of the data signal received by the site / the access point currently; and C, setting the transmission power of a transmitter and performing the fine-tuning on the transmission power when necessary according to the intensity of the data signal received by the site / the access point currently. According to the method, a special MAC frame is added to verify the data transmitting and receiving performance, and a special method is adopted to estimate the intensity of the data signal transmitted by a channel and to calculate the data receiving ratio of the site / the access point which can serve as quantitative data for judging the fading of the channel of a wireless link, and a reference frame of the communication efficiency of a device.

The invention discloses a fast detecting method and device for a static vehicle target. The fast detecting method includes the following steps that images are collected, wherein vehicle images are obtained; the images are preprocessed, wherein normalization is conducted on the sizes of the vehicle images, and the vehicle images are converted into a grey-scale map; entropy information is extracted, wherein pixel level traversal is conducted on the images through search boxes, and pulse iteration average entropy information of the partial images in the search boxes is extracted; rough positioning is conducted on the vehicle target, wherein the images with the pulse iteration average entropy value larger than that the target entropy value are taken as vehicle target rough positioning images; the vehicle target is determined, wherein the vehicle image with the largest pulse iteration average entropy value in the same picture area is reserved as a target vehicle search result; the vehicle target is presented in an original large image, and positioning of the vehicle target is completed. According to the fast detecting method and device for the static vehicle target, robustness, rapidness and transportability of a pulse coupling neural network feature extraction method are used, the feature of the pulse iteration average entropy is selected as the judgment basis, and the speed of detecting the static vehicle target is greatly increased.
