The invention belongs to the technical field of computers and provides a method and device for establishing virtual test rooms.The method comprises the following steps that learning requests input by users are received, wherein the learning request at least comprises learning subjects and grades selected by the users; the positions of the users are acquired, the number of the learning requests which are received in the preset time quantum and located at the positions are monitored in real time, and when the number of the learning requests is larger than a preset number threshold, a virtual test room is established for the all users located at the positions, and review test questions are issued to the all users in the virtual test room; an online test room is provided for the users who are located at the same region range, request for reviewing the same subject and belong the same grade, interestingness of reviewing lessons is improved, and the availability of reviewing lessons and reviewing efficiency of the users are improved.

The invention discloses a method and system for load balancing control in a wireless ad hoc network system. The method includes: setting the management frequency point as the second receiving frequency point when the opening duration of the management frequency point is longer than the set threshold; setting the second device Register under the first receiving frequency point and the second receiving frequency point of the first device; obtain the first number and the second number of the second device mounted under the two service frequency points, and when the first preset condition is met Switch the service frequency points connected by the first set number of second devices; obtain the third number and the fourth number of the second devices mounted under the two service frequency points whose communication quality is less than the second set threshold, and meet the The second preset condition is to switch service frequencies connected by a second set number of second devices. The present invention can monitor and dynamically adjust the load quantity under two service frequency points in real time to ensure the quality of data transmission; the management frequency point of the LoRa base station that multiplexes the outdoor unit is the service frequency point, which reduces the waste of frequency point resources.

The invention discloses an automatic feeding device for an SMA fiber material for a regenerated asphalt material. The automatic feeding device comprises a feeding platform, a storage mechanism, a feeding mechanism and a feeding chute, wherein the storage mechanism comprises a storage bucket, partitioning plates, an arc-shaped protecting plate and a rotating system; the storage bucket is partitioned into a complex number of storage areas by the partitioning plates; a complex number of fiber packets are stacked inside each storage area; a discharge hole is correspondingly formed in the side wall of the bottom of each storage area; the arc-shaped protecting plate encircles the side surface of each discharge hole; notches corresponding to the discharge holes are formed in the arc-shaped protecting plate; the feeding mechanism comprises a vacuum sucker, a grasping device, a grasping cylinder and an air control module; the grasping device is fixed at the front end of the grasping cylinder; the vacuum sucker is fixed on the outer surface of the grasping device. According to the automatic feeding device, the quantitatively packaged fiber packets can be overlapped in the storage areas of the rotational storage bucket and can be automatically grasped and fed by using the grasping cylinder and the vacuum sucker, then the feeding amount of a single batch is accurate, and the production efficiency and the quality of the regenerated asphalt material can be improved.

The invention discloses a kit for monitoring the activity of a signal pathway in vivo, which is composed of an electron transfer monitoring probe and a living body imager. The living body imager is wirelessly connected with the electron transfer monitoring probe to detect its fluorescence intensity. The electron transfer monitoring probe It includes a light-emitting element, an electron-conducting element and an identification element, the light-emitting element and the electron-conducting element are combined by hydrophobic force, and the electron-conducting element and the identification element are combined by a phosphodiester bond. The electron transfer monitoring probe of the present invention can be used for in vivo real-time dynamic monitoring of the activity of the signal pathway, and the identification element is a nucleic acid aptamer and other substances with targeted identification capability, which can realize real-time dynamic identification of target molecules in vivo.

The invention relates to an RFID matrix distributed personnel positioning monitoring system and a method thereof. The system comprises a superhigh frequency RFID label matrix, a monitoring antenna and a monitoring control device, wherein the superhigh frequency RFID label matrix is fixed under the ground of a monitoring area; the monitoring antenna is arranged above the monitoring area; and the monitoring control device is connected with the monitoring antenna. The method comprises: numbering and positioning RFID labels in the RFID label matrix one by one to establish a standard matrix table;detecting and reading RFID labels in an electric wave covered area; calculating the number and positions of personnel in the RFID label matrix according to positions and the number of the RFID labelswhich can not be read, and a fixed layout distance of adjacent RFID labels; and calculating moving directions and speed of the personnel according to a sequence and time interval of the RFID labels which can not be read. The RFID matrix distributed personnel positioning monitoring system and the monitoring method thereof can effectively position and monitor the personnel and realize low cost, stable and reliable work performance and wide application range, thereby establishing a firm foundation for further popularization and development of zone positioning monitor technology.
