Embodiment Construction

[0031] The invention includes a message box section and a control box section. The letter box part includes a human body infrared sensing module, a photosensitive sensing module and two relay modules. The control box part includes a micro control unit MCU, a GSM SMS module, a radio frequency card reader module and a display module.

[0032] The overall workflow of the smart mailbox system based on GSM and RFID technology is as follows:

[0033] When the human body approaches, the LED inside the message box will be lit; if the human body does not move, the light will turn off after a preset eight-second delay.

[0034] When a thick letter is put into the mailbox, the LCD screen on the control box will display "MAILINSIDE", indicating that the letter has been sensed; at the same time, the GSM SMS module will start The mobile phone number in the AT command sends a preset text message.

[0035] When the user puts the correct IC card with the pre-stored card serial number close ...

Abstract

The invention relates to an intelligent mailbox system based on GSM and RFID technologies. When a human body approaches, an internal lighting system is lightened, so night operation and observation ofinternal conditions of a mailbox are facilitated. When letters are put into the mailbox, the information is sent to remind a mailbox owner. The mailbox owner can verify the identity through an IC card and open the mailbox. The mailbox is mainly used for solving problems that a traditional mailbox is poor in passivity, safety and timeliness. Distance observation of a human body is mainly achievedthrough an infrared induction principle, receiving observation is achieved through a photosensitive sensor, the identity of a user is verified through the radio frequency technology, and a GSM communication module is controlled to send the information through AT instructions stored in a single-chip microcomputer. The user can be reminded not to miss important letters by combining with a GSM network so that mechanical labor of checking the mailbox by the user is reduced; the mailbox is combined with the RFID technology to be used for user identification, the user can open the mailbox conveniently, and safety of the mailbox is improved.

Description

technical field [0001] The invention relates to a letter box, in particular to an intelligent letter box system based on GSM and RFID technology. Background technique [0002] Under the impact of the rapid development of the Internet and the express delivery industry, the existing traditional mailboxes have gradually become trash cans for advertisements, leaflets and utility bills. In offices where traditional mailboxes are used relatively frequently, due to their lag and passive It is also replaced by e-mail and other communication tools, and it is only occasionally used in occasions where paper reports are mandatory and will not be affected by information lag. [0003] Although the letter box seems "outdated", it is still necessary to exist. First of all, various public service businesses need to be delivered to the parties involved, such as bank bills, insurance policies, water bills, electricity bills, gas and other paper letters; secondly, some residents have the habit...
