RFID region partitioning and scope monitoring system and method

Abstract

The invention discloses an RFID area dividing and range monitoring method. The method comprises the following steps: covering a range to be divided and monitored with a signal transmitted from an RFID antenna, and receiving a signal reflected by an object in the dividing and monitoring range in response to the transmitted signal; reflecting the signal transmitted from the RFID antenna by a spacer to cause the reflected signal to rapidly attenuate after leaving the area divided by the spacer; reading information of the signal received by the RFID antenna to detect an RFID tag in the divided area; and monitoring the area according to judgment conditions stored in advance. The RFID area dividing and range monitoring method and a system thereof can divide a detection range into an 'allowable work area' and an 'forbidden work area', and effectively monitor working conditions of staff in the work area, thus significantly improving the monitoring performance of the detection range, improving safety and enhancing convenience for users.

Description

Technical field [0001] The invention relates to an RFID area division and range monitoring system and a method for dividing and monitoring the detection range by using the system. Background technique [0002] At present, in the process of construction and daily operation and maintenance of the mobile computer room, the following requirements exist for the management of various equipment in the computer room and the personnel entering the computer room: (1) It is hoped to divide the area in the computer room (usually these areas are all It is based on a row of equipment), and considering the fire safety and actual operation conditions, these areas cannot be "hard isolation" through walls or fences, and should be "soft isolation" through some means; (2) It is hoped that real-time positioning monitoring will be carried out for different personnel, and the system will automatically determine whether their location is an "allowed working area" or a "forbidden working area". If the pe...

Problems solved by technology

[0003] For the above requirements, there are two main difficulties: (1) There is a lack of means for small-scale area division, and the traditional cellular area division is too strong and the flexibility is not good; It can monitor the simple situation of the border, but it is powerless to monitor the interior of the area or when more specific information needs to be monitored

[0004] In addition, how to locate people indoors with small efforts is also a thorny issue. At present, the widely used positioning systems such as GPS or base station triangulation are all aimed at large-scale scenes.
