The invention provides a pedestrian crosswalk signal light self-adaptive control method and system utilizing a video tracking technique. According to the pedestrian crosswalk signal light self-adaptive control method, through the video tracking detection technique, pedestrians around the pedestrian crosswalk can be continuously tracked; when the pedestrians are detected to cross street and the pedestrian crosswalk signal light is red, whether the time within which a motor vehicle on the motor vehicle road reaches the pedestrian crosswalk exceeds the time within which the pedestrians cross the street or not is detected; if the time within which the motor vehicle on the motor vehicle road reaches the pedestrian crosswalk exceeds the time within which the pedestrians cross the street, green light passing signal is first provided for the pedestrians and when all the pedestrians cross the pedestrian crosswalk, the green light signal is provided for the motor vehicle instantly; the green light signal is provided for the pedestrians and the passing of the motor vehicle is not affected in the process; the green light time is shortened to the largest extent; moreover, through the adoption of the technical scheme, the pedestrians lingering in the street-cross waiting region but not intending to cross the street are reminded to leave the street-cross waiting region so as to prevent the situations that the passing signal is provided for the pedestrians not crossing the street, the green light resource is wasted and the road crossing efficiency of motor vehicle is reduced.

The invention provides a method and a device for self-organization network time synchronization and can improve the system convergence speed and reduce a system load. The method comprises steps that a node having the highest phase in a cluster is taken as a cluster head node, time synchronization of the cluster head node and cluster head nodes of other clusters is carried out, and other nodes of the cluster are taken as in-cluster nodes which enter into a dormant state; the in-cluster nodes in the dormant state stop dormancy and realize time synchronization with the cluster head node of the cluster. The device comprises an inter-cluster synchronization module used for acquiring the node having the highest phase in the cluster and taking the node as the cluster head node and an in-cluster synchronization module used for making the in-cluster nodes in the dormant state stop dormancy and realizing time synchronization of the in-cluster nodes and the cluster head node of the cluster, wherein time synchronization of the cluster head node and the cluster head nodes of other clusters is carried out, and the other nodes of the cluster are taken as the in-cluster nodes which enter into the dormant state. The method is suitable for the network technology field.

The invention discloses a sustained-release and controlled-release balloon floating system, which can ensure that the drug can float at the top layer of the stomach contents after entering body and can not enter into small intestine along with the evacuation of foods, so as to improve the drug efficacy. The invention includes a balloon which can provide buoyancy to allow the system to be floated at liquid surface and a sustained/controlled-release preparation containing pharmacological active substances. The system includes three parts: a balloon shell I, gas II and the sustained-release and controlled-release preparation III containing drugs, wherein the gas II occupies one end of the balloon shell I, and the other end is occupied by the sustained-release and controlled-release preparation III, and the two are or are not separated by a partition board/diaphragm IV. The floating preparation which is prepared by the method of the invention can respectively and independently regulate the controlled-release time and the floating time during the prescription and process designs, and when the characteristics of one part of the two parts change, the characteristics of the other part do not be affected, thus, the exploration processes of the prescription and process can be greatly simplified.

The invention is suitable for the technical field of communications and provides a task processing method and system. The method comprises the steps of sending a first temporary directory creation request to a distributed application coordination service zookeeper before one or more servers execute a task; selecting one server by the zookeeper, and sending information of agreeing to create a first temporary directory to the selected server, wherein the selected server is a first server; creating the first temporary directory uniquely corresponding to the task at the zookeeper by the first server; and executing the task corresponding to the first temporary directory by the first server. Through the method, the same task can be ensured not to be repeatedly executed due to a time deviation of the server.

The invention discloses a well head sampling method of an oil and gas well. The well head sampling method includes the steps that formation fluid flowing in the horizontal direction is changed into formation fluid flowing in the vertical direction through a sampling device; in the vertical direction, it is achieved that uneven-flowing fluid is changed into even distribution and flowing fluid through a filtering and mixing device; after the fluid evenly flows, a certain quantity of samples are sampled at different positions of a circulation channel through a stretchable sampling probe till a special sample bottle is full. Under the condition that the well head sampling condition meets PVT analysis of a laboratory, underground fluid samples can be completely replaced with the samples sampled with the sampling method, the sampling time is set during stable-flowing finding production, and meanwhile getting of capacity data of the oil and gas well is not influenced; compared with an underground fluid sampling method, according to the well head sampling method, the operation time is not additionally occupied, a special sampling tool is not required, the operation time of a whole well is saved, and operation cost is reduced.

The invention discloses a signal detection device for energy distribution network fault recovery. The device comprises a shell, the surface of the shell is fixedly connected with a display screen, a partition plate is arranged below the display screen, the partition plate is fixedly connected with the surface of the shell, the lower part of the partition plate is fixedly connected with a brightness display lamp, an alarm indicator lamp is fixedly connected with one side of the brightness display lamp, a button is fixedly connected with the lower portion of the brightness display lamp, the button is connected with the brightness display lamp through an electric wire, and a signal column is fixedly connected with the interior of the shell. According to the invention, a signal strengthening module and a radio module are arranged, the performance of the signal detection device can be effectively enhanced, the situation that the progress of other workers is delayed due to the fact that a signal source of the signal detection device is weak during detection of workers is avoided, detection can be conducted in a wireless mode, a large amount of time is shortened, and the time of other workers is not affected.

The invention relates to a blockchain-based intelligent detection system for a communication network switch. The blockchain-based intelligent detection system for a communication network switch includes a mounting frame, wherein an adjusting conveying device is arranged between inner walls of the mounting frame; the middle portion of the mounting frame is provided with lifting control devices at intervals from the front to the rear, and the inner walls of the left and right ends of the mounting frame are symmetrically provided with stabilization auxiliary devices; detection execution grooves are formed in the left end of the mounting frame at intervals from the front to the rear; and detection execution devices are arranged in the detection execution devices. The blockchain-based intelligent detection system for a communication network switch can solve the problems that in the production test process, the switches are manually carried to a specific detection location and are detected one by one manually, and before detection of the switches, the switches are not packaged, so that the switches are easy to be damaged due to collision during the process of manually carrying the switches and then the service life of the switches can be influenced, and manual detection of the switches one by one consumes long time, and the labor intensity is high and the working efficiency is low.
