Distance extension of radio frequency technical handheld mobile computer

Abstract

The invention relates to distance extension of a radio frequency technical handheld mobile computer. A central control unit of a distance extension system of the radio frequency technical handheld mobile computer is connected with a radio frequency function module, a data storage function module and an input / output interface module respectively; and a power control module is connected with the central control unit, the radio frequency function module and the input / output interface module. A method comprises the following steps: labels are numbered and positioned one by one to establish a standard matrix table; the labels are detected and read; and the number, positions, moving directions and moving speeds of personnel in the label matrix are measured and calculated according to fixed layout separation distances of the distance extension of the radio frequency technical handheld mobile computer. Through adopting the distance extension of the radio frequency technical handheld mobile computer, personnel can be positioned and monitored efficiently; the structure is simple; the cost is low; the working performance is stable and reliable; the range of application is wide; and a firm foundation is laid for the further popularization and development of regional positioning monitoring technology.

Description

technical field [0001] The invention relates to the technical field of RFID radio frequency identification Background technique [0002] RFID (Radio Frequency Identification) is a radio frequency identification technology. Since the electromagnetic waves of UHF (400MHz~2.4GHz) RFID tags are easily absorbed by water and attenuated, in actual use, they are often affected by liquid containers or rich in water. The occlusion of substances (such as high water content items, human body, animal body, etc.) will cause the situation that UHF RFID tags cannot be read. [0003] At the same time, in modern life, there are already various navigation and positioning devices, such as GPS, etc., but the cost of these devices and the operating cost of the system are relatively high. Especially for the location monitoring system of regional personnel or objects, there is no good technology that can be popularized and applied on a large scale at present, which brings great inconvenience to pe...
