The invention discloses a method for system for monitoring multi-dimensional deformations of electric transmission lines in real time on the basis of differential positioning. According to the methodand system, a base station is electrified to carry out measurement or increase measurement frequency, longitude and latitude information of the base station is updated in real time by utilizing a known base station coordinate, and a measured carrier phase observed value, a measured pseudo-range observed value and the base station coordinate are transmitted to a background server through a 4G network in an RTCM format or a self-defined format; a monitoring station uploads acquired field state data and a command for processing a client to the background through the 4G network in the RTCM formator the self-defined format; the background server receives the information sent by the base station and the monitoring station and carries out single-system and multi-system combined calculation; andthe background server converts the three-dimensional position of the base station into a longitude, a latitude and an altitude so as to obtain the position information, relative to the base station, of the monitoring station to complete the real-time monitoring. The method and system can be used for monitoring the multi-dimensional postures of electric transmission line towers on complicated geologies so as to ensure the safe operation of the electric transmission lines.

The invention is suitable for the technical field of cloud detection and provides a method, device and system for task operation processing. The method comprises the steps of submitting task operation in a cloud detection system; detecting task types of task operation, and enabling the task types to comprise a cluster task type and a trans-cluster task type; if the task type is the cluster task type, utilizing a preset cluster scheduler in the cloud detection system to process the task operation with the task type being the cluster task type; and if the task type is the trans-cluster task type, utilizing a preset trans-cluster scheduler in the cloud detection system to process the task operation with the task type being the trans-cluster task type. The cluster task type is a type of utilizing one cluster to process the task operation, and the trans-cluster task type is a type of utilizing at least two clusters to process the task operation. The conditions that the system collapses easily are avoided, and system stability and task processing efficiency are improved.

The invention relates to the technical field of computers, and provides a traffic flow control method, device and equipment and a storage medium. The method includes the steps: calculating the numberof replenishable tokens through obtaining the to-be-accessed data in an interface access request, the total number of access tasks included in the to-be-accessed data and the target Interface, calculating target access data, monitoring the target access data, and recording the actual traffic data when the target access data passes through the target interface, obtaining a preset standard value ofeach traffic parameter, comparing the actual value of each flow parameter with a standard value, and marking the flow parameter with the actual value being greater than the standard value and the corresponding actual value as abnormal data; searching a target flow control mode corresponding to the abnormal data in a preset adjustment library, and performing the traffic flow control of the target interface in the target flow control mode. The method achieves an improvement in the use efficiency and maintainability of the target interface.

The invention relates to a transmission method and a player for a point-to-point mobile streaming media, which support a streaming media player to share and dispense the contents organized by an operator in a mobile communication network and comprise the following steps of: sending a fragment request periodically according to the requirement of playing the streaming media information, recording the time emitted by the fragment request and adding the time to a request list, receiving the response of the fragment request, deleting the fragment request that receives response from the request list, judging whether the fragment requests in the request list is overtime according to the time emitted by every fragment request periodically by an arranged timer; if not, turning to the step (1) and if so, deleting the overtime fragment request from the request list and re-dispensing a request and turning the step (2). The invention realizes the reliable transmission of the UDP by the improved upper layer application, and overcomes the defects that the UDP of the existing P2P transmits a large amount of residual messages and corresponding adjustment can not be carried out according to the fluctuation of the network condition.
