The invention discloses an electronic scale with automatic switching of measuring ranges and weighing method. The electronic scale includes a tray, three pressure sensors with different measuring ranges and a pedestal; a control unit is arranged in the pedestal, and a data input device and a display output device are arranged on the pedestal, and are connected with the control unit; the three pressure sensors are adjacent to each other in an end-to-end manner to form a regular triangle, the upper end faces of the three pressure sensors are located in the same horizontal plane, the upper end face after each pressure sensor is turned over around itself is still in the horizontal plane, and the three pressure sensors are connected with the control unit; and three drive circuits and three direct current motors are arranged in the pedestal, the three drive circuits are connected with the control unit, the three direct current motors are connected with the three drive circuits, and the three pressure sensors are connected with the three direct current motors. The electronic scale provided by the invention has the function of adaptive switching of measuring ranges, thereby facilitating weighing of objects of different weights by users.

The invention discloses a multifunctional multiplexer of a scatter communication system. The multifunctional multiplexer is composed of parts including a simulation user module, a media compression module, a main controller module, a scatter modem interface module and the like. The scatter modem interface module is responsible for protocol processing of the overall multifunctional multiplexer andservice adaptive transmission processing of an equipment channel of the overall equipment. A sent frame structure is dynamically adjusted according to the current voice usage time slot occupation condition. Once adjusting of a sending end is completed, a receiving back end dynamically adjusts the received frame structure according to the frame structure condition of the sending terminal, and thenthe overall communication lossless adaptive switching is completed. The multifunctional multiplexer meets the mixed transmission and adaptive transmission requirements of SIP-based voices and Ethernetservices in the scatter channel, has the advantages of being easy to set and high in integration level and achieving multiple transmission speeds and has a broad application prospect in the scatter communication system.
