Embodiment 1

[0033] Such as figure 2 As shown, it is an embodiment of the present invention, the read-write module RM1 has 4 radio frequency ports RF1, RF2, RF3, RF4, through 4 radio frequency cables and 4 plate-shaped directional antennas A1, A2, A3, A4 connection. The four plate antennas are installed on the access control frames F1 and F2 respectively, and personnel or materials pass through the channels defined by F1 and F2. Like RM1, the read-write module RM2 is also connected with 4 antennas to control another channel.

[0034] When a person or object with a UHF electronic tag enters the passage, the sensor S1 senses the corresponding information and sends it to the main control board C1. The module RM1 / RM2 of the channel works, and the corresponding module polls the connected antenna number to complete the collection of tag signals in the channel and report to the main control board C1. When the two channels have targets entering at the same time, the read-write modules RM1 and ...

Embodiment 2

[0037] Such as image 3 As shown, it is another embodiment of the present invention, the read-write modules RM1 and RM2 are controlled by the main control board C1, and the antennas A1, A2, A3, and A4 communicate with the read-write modules through four ports RF1, RF2, RF3, and RF4 The writing module RM1 is connected, and the antennas A5, A6, A7, and A8 are respectively connected to the reading and writing module RM2 through four ports RF5, RF6, RF7, and RF8; the antennas A1, A2, A3, A4, A5, A6, A7, and A8 are respectively fixed On access control frames F1, F2, F3. The main control board C1 controls the reading and writing modules RM1 and RM2 to switch the radio frequency port to poll each antenna to complete the RFID reading and writing work.

[0038] When a person or object with a UHF electronic tag enters the channel, the sensor S1 senses the corresponding information and sends it to the main control board C1. The main control board C1 starts the reading and writing module...

Abstract

The invention provides a UHF access control system. The UHF access control system comprises a main control panel, a power module, two reading-writing modules, at least two sensors and at least two servo mechanisms. The power module, the two reading-writing modules, the at least two sensors and the at least two servo mechanisms are connected with the main control panel; the main control panel is used for controlling the reading-writing modules, the sensors and the servo mechanisms to work and receiving and responding orders issued by an upper computer or automatically uploading data to a server; the power module is used for feeding direct currents into the main control panel; the reading-writing modules are used for necessary physical layer processing and protocol stack processing which are read and written through the RFID technology and receiving the orders and reporting data; the sensors are used for detecting whether persons or objects enter an aerial radiation field to trigger card reading; the servo mechanisms have the indicative function. The UHF access control system has the advantages of being high in data processing capacity and small in security hole, and meanwhile the corresponding capacity and the security level of the UHF access control system are improved.

Description

technical field [0001] The invention relates to the field of management systems, in particular to a UHF access control management system. Background technique [0002] RFID (Radio Frequency Identification) technology is a wireless technology that uses radio frequency energy to propagate in space to achieve non-contact information transmission, and achieves identification targets through the transmitted information. This technology originated in World War II, and its original purpose was to identify the identity of the fighter plane as friend or foe. Since the 1980s, with the development and progress of integrated circuit technology, RFID technology has developed rapidly. At present, RFID products can be found on the market, and the working frequency bands cover the following frequency bands: LF, HF, VHF, UHF (Ultra High Frequency, ultra-high frequency) and microwave frequency bands. UHF frequency band RFID technology has the characteristics of long identification distance,...
