Embodiment Construction

[0034] Such as figure 1 As shown, the hardware part of the present invention includes: microcontroller, memory, clock, radio frequency transceiver chip, peripheral hardware, RS-232 interface and power supply module, wherein the composition and function of each module are as follows:

[0035] (1) Microcontroller CPU: The present invention selects RISC 16-bit MSP430 series microcontrollers. The microcontroller CPU has ultra-low current consumption, works at a voltage of 1.6~3.6V, and has a variety of power-saving operating modes to choose from, running at 2.2V , 1MHZ according to the operating mode, the working current is from 0.1uA to 200uA, each module is completely independent operation, timer, I / O port, A / D conversion, watchdog, etc. can run independently in the state of CPU sleep. When the CPU is required to work, any module can wake up the CPU through an interrupt, so that the system can run with the lowest power consumption. At the same time, the CPU has abundant resourc...

Abstract

Provided is a low power dissipation hand-hold RFID patrolling device and a method realizing the same, including a microcontroller, a memorizer, a clock, a RF receiving chip, peripheral equipment, an RS interface and a battery module. When the RF receiving chip does not read the label, the device is in the sleep state; when reading the label, the microcontroller CPU awoke the device; the microcontroller CPU controls each part to work, when the CPU does not work, the device is in the sleep state namely a low power dissipationmode; when the CPU is working, the RF receiving chip, or the peripheral equipment, or the RS interface is in the working mode through the intermit awakening, thereby the whole device operates in low power dissipation. The device of the invention has low power dissipation, durable action, charging function and increased usability.

Description

technical field [0001] The invention relates to a hand-held RFID patrol device and a method for realizing low power consumption of the device, and is suitable for security patrol attendance systems of various units. Background technique [0002] In recent years, with the development of society and the improvement of the security system, various units have put forward higher requirements for their own security and management. However, in the work of security patrols, it is mainly in the manual recording of attendance and patrol information. The stage is very cumbersome and requires a lot of manpower. Although there has been a patrol system using RFID, such as a patrol system and method disclosed in Chinese Patent Application No. 200310123594.7, it combines RFID with the magnetic field sent by wireless electromagnetic waves to perform wireless data identification and retrieval, including setting it on the patrol panel The radio frequency identification tag and transceiver rec...
