Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0010] see figure 1 , is a flow chart of the antenna hierarchical extension method of the present invention. In step S100, the antenna controller is connected to the read-write device.

[0011] In step S102, the read-write device controls the working state and working time of the antenna controller.

[0012] In step S104, the antenna controller is connected to a next-level antenna controller or antenna.

[0013] In step S106, the antenna controller determines whether it is connected to the antenna.

[0014] In step S108, if connected to the plurality of antennas, the antenna controller controls the working state and working time of the antennas.

[0015] In step S110, if it is not connected to the antenna, if it is connected to the antenna, the antenna controller controls the working state and working time of the antenna. The multiple anten...

Abstract

The invention provides an antenna classification extension method. The method comprises the following steps: connecting an antenna controller to a read / write device; controlling the working state and the working time of the antenna controller by the read / write device; connecting the antenna controller with a next stage antenna controller or an antenna; and judging whether the antenna controller is connected with the antenna by the antenna controller. The invention also provides an antenna classification extension system. In the antenna classification extension method and the antenna classification extension system provided by the invention, communication channels of the read / write device are extended by arranging the antenna controller between the read / write device and the antenna, and the antenna controller can be connected with the next stage antenna controller so as to realize multistage extension; and therefore, one read / write device can extend enough antenna channels to use, the complexity of an application system is reduced, and the construction cost of the application system is reduced.

Description

【Technical field】 [0001] The present invention relates to antenna extension, in particular to a method and system for antenna hierarchical extension. 【Background technique】 [0002] With the continuous development and promotion of radio frequency identification (Radio Frequency Identification, RFID) technology, more and more fields begin to use this new technology. In the UHF RFID application field, the read-write device and antenna are important components of the application system, but due to the constraints of structure and other factors, the general read-write device only has four antenna channels, and the number of antennas required by many application fields Far more than four channels, currently only can be solved by adding read-write devices, but this method not only increases the cost of the system, but also increases the complexity of the system and reduces the reliability of the system. 【Content of invention】 [0003] In order to solve the problems in the prior...
