Embodiment Construction
[0018] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0019] First, the working principle of the RFID area division and range monitoring system and method of the present invention will be described. Here, the range division and monitoring system and method solutions based on RFID technology are mainly based on the long distance of RFID monitoring, and combined with the specific characteristics of specific mobile computer room equipment (equipment racks have good reflection performance on RFID radio frequency signals). Scope division and personnel area monitoring are unified on one information platform for resolution.
[0020] Among them, the RFID antenna is hung in the corridor of the two rows of equipment racks. Due to the reflection effect of the equipment rack on the radio frequency signal, the reading range of one antenna can just cover the entire corridor. Once out of the corridor area, the r...

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 spacerto 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, improvingsafety 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 using the system to divide and monitor the detection range. Background technique [0002] At present, in the process of construction and daily operation and maintenance of the mobile computer room, there are requirements in the following aspects for the management of various equipment in the computer room and the staff who enter the computer room: (1) It is hoped to divide the computer room into areas (usually these areas are It is based on a row of equipment), and in consideration of fire safety and actual operation, these areas cannot be "hardly isolated" by walls or fences, and should be "softly isolated" by some means; (2) It is hoped that different personnel can be monitored in real time, and the system can automatically judge whether their location is a "permitted work area" or a "prohibited work area". If the person is found to enter the "prohibited work ...
