Intelligent trunk low-frequency emission trigger

Abstract

The invention provides an intelligent trunk low-frequency emission trigger, which comprises a low-frequency analog circuit and a low-frequency generation circuit which are electrically connected, anda power supply module for supplying power to the low-frequency analog circuit and the low-frequency generation circuit, wherein the low-frequency analog circuit comprises a digital counter chip, and the digital counter chip outputs regular high-low pulses by being externally connected with a crystal oscillator and sends the regular high-low pulses to the input end of the low-frequency generation circuit; the low-frequency generation circuit periodically controls on-off of the triode according to input high-low pulses, generates pulse signals of a fixed period, and sends out low-frequency signals through electromagnetic induction. The low-frequency signal emission is realized, the intelligent trunk in a dormant state is awakened, manual misoperation is reduced, low-power-consumption work ofthe intelligent trunk is ensured, and the service life of a battery is prolonged to the maximum extent.

Description

technical field [0001] The invention relates to the field of financial security, in particular to an intelligent tail box low-frequency emission trigger. Background technique [0002] The tail box is a tool for the transfer and preservation of important properties such as funds and bills in financial fields such as banks. At present, there are many bank outlets and a large number of trunks. It is difficult to manage, and the operation is cumbersome and error-prone. There are security risks such as handover, loss or theft, and illegal opening of the tail box. For example, after the tail box is illegally opened, the bank cannot know the time and times of illegal opening in a timely and accurate manner, and cannot respond in time, nor can it call the police in time or take corresponding processing measures. [0003] Although the existing tail box has a handover recording function, these recorded data are stored in the main control chip of the tail box, and the main control ch...

AI Technical Summary

Problems solved by technology

In order to achieve power saving and low power consumption, most tail boxes use mechanical unlocking to wake up the main control chip or activate the main control chip with buttons, and to obtain the operation records and alarm information of the tail box need to be read through the USB data cable after opening the box, resulting in a large number of Misoperation exists, neither can achieve real power saving
