The invention discloses an expandable mesh parabolic cylinder antenna, and mainly solves problems of large storage volume and low surface precision in the prior art. The expandable mesh parabolic cylinder antenna is composed of an expansion mechanism (1), a mesh surface supporting mechanism (2), flexible cables (3) and a wire mesh (4). The mesh surface supporting mechanism (2) is symmetrically installed on both sides of the expansion mechanism (1). The flexible cables (3) are interlaced on the mesh surface supporting mechanism. The wire mesh (4) is disposed on the flexible cables (3). During folding up, the expansion mechanism is retracted along a straight line; the mesh surface supporting mechanism is folded up and retracted on both sides of the expansion mechanism; and the flexible cables and the wire mesh are retracted in remaining space of the mesh surface supporting mechanism. During expansion, the expansion mechanism is expanded along a straight line; the mesh surface supporting mechanism is stretched towards both sides of the expansion mechanism (1); and the flexible cables tighten and support the wire mesh (4) so as to form a parabolic cylindrical surface. The expandable mesh parabolic cylinder antenna has the advantages of small storage volume and high surface precision, and can be used for searching targets in the air and measuring target azimuths.

The invention is applicable to the technical field of communication, and provides a method for sending dynamic scene information, a display method, a server and a mobile terminal. The server in the present invention obtains the information push request sent by the first terminal, generates corresponding dynamic scene information resources, and sends the dynamic scene information resources to the second terminal, and the second terminal generates dynamic scene information according to the dynamic scene information resources, and displays On the preset page, if the preset page contains status parameters, a status update request is generated to the server, and when the server receives the status update request sent by the second terminal, it forwards it to the first terminal and receives feedback from the first terminal The server sends the current status information corresponding to the status update request to the second terminal, and the second terminal updates the status parameters according to the current status information, which reduces transmission costs and waste of storage resources.

The present application discloses a distance-based information sending method, device, computer equipment, and storage medium. The method includes: acquiring a target mobile phone number, and acquiring characteristic information of a user related to the target mobile phone number; The mobile phone number is mapped to a specified vector in a high-dimensional virtual space; multiple temporary vectors are selected from multiple standard high-dimensional vectors; multiple first distances are calculated, wherein the first distance is the specified vector and the specified vector The distance between the temporary vectors; if a plurality of the first distances are unevenly smaller than the preset distance threshold, then according to the corresponding relationship between the first distance-temporary vector-information sending strategy, the designated value corresponding to the first distance with the largest value is obtained An information sending strategy, and sending information to the target mobile phone number according to the specified information sending strategy. In this way, information can be sent in a targeted manner, and the cost of sending information can be reduced under the premise of ensuring the delivery rate.
