A rfid super positioning exciter

Abstract

The invention discloses an RFID super positioning exciter. The positioning exciter comprises an ARM main control module, a 2.4 G transceiving polling module, a 125K signal programmable power supply adjusting module, a 125K signal synthesizing and amplifying module and a signal transmitting module. The ARM main control module receives polling data in real time through the 2.4 G transceiving pollingmodule. The 125K signal synthesis and amplification module is used for synthesizing and amplifying the data. The signal transmitting module is used for transmitting a wireless signal. The 2.4 G transmit-receive polling module is used for realizing polling transmit-receive of 2.4 G signals. The 125K signal programmable power supply adjusting module is used for adjusting the voltage of a power supply. The RFID super positioning exciter is scientific and reasonable, the wireless signal power supply is simple in structure and safe and convenient to use. Time slot control over 2.4 G signals is achieved through the 2.4 G receiving and sending polling module, the problem of mutual collision between positioning exciters is avoided, the 125K signal programmable power supply adjusting module is used for adjusting the power supply voltage, and stepless adjustment over the wireless signal power is achieved.

Description

technical field [0001] The invention relates to the technical field of actuators, in particular to an RFID super positioning actuator. Background technique [0002] The relevant technology available in the market at present is that the excitation mode of the 125KHz positioning base station is a resistive voltage division type voltage excitation mode, which has relatively low efficiency and cannot realize stepless and precise adjustment, resulting in poor 125K positioning function characteristics and troublesome on-site debugging, and because each The positioning range and working distance of the 125KHZ positioning base station are limited, such as (3.5 meters radius), which makes it difficult to meet the coverage requirements of positioning triggers, especially in irregular open spaces, the layout of the positioning base station is a headache, not only the required There are a large number of positioning base stations. Due to the irregular site, the positioning coverage over...

Problems solved by technology

[0003] The purpose of the present invention is to provide an RFID super positioning exciter to solve the problems in the prior art that the efficiency is relatively low, stepless precision adjustment cannot be realized, on-site debugging is troublesome, and the positioning range and working distance are limited, resulting in the coverage of positioning triggers. It is difficult to meet the demand, especially in irregular open spaces, where the number of positioning base stations required is large and interferes with each other, and the positioning distance cannot be adjusted accurately. Specific application scenarios will cause positioning interference and lack of positioning information.
