Description

An online picture-text mailbox system

technical field

The invention relates to a living electronic product, in particular to an online picture-text mailbox system.

Background technique

Today, with the increasingly developed network and communication, mailboxes are still indispensable in the daily life of residents. Credit cards and other related letters, various notices, newspapers, etc. are still distributed through newspaper boxes, and mailboxes will exist for a long time. With regard to the letter box system, there is room for improvement in two aspects. First, the information exchange between people and the outside world is increasingly rich, such as the Internet, telephone, and various media advertisements. In contrast, the mailboxes that people often open can give people very little information. Second, because the amount of messages in mailboxes is decreasing, people don't even open their mailboxes every day, and they often don't know whether their letters have arrived, causing delays.

In response to the second question, in recent years, relevant personnel have begun to pay attention to mailboxes, detected mail delivery events through infrared, mechanical switches, etc., and proposed a letter arrival notification scheme based on wired and wireless. Since the mailbox is a low-cost and convenient facility, the wired solution often involves secondary wiring, which is not cost-effective and practical. Most of the residential buildings in our country are multi-storey and high-rise. The simple wireless transmission scheme has a short communication distance and is difficult to apply. However, increasing power consumption to increase the communication radius will lead to short battery life, large replacement and maintenance, and limited application. Related to the first question is the rapid development of elevator advertisements in recent years. Community advertising has become a new growth point of advertising. However, at present, this type of advertisement has obvious commercial characteristics, and there are shortcomings such as poor service characteristics for residents, slow updates, and insufficient information delivery.

Contents of the invention

In order to enable residents to check whether there is a letter in the mailbox at any time without leaving home, so as to avoid the delay of the letter; to make the letterbox have the ability to receive and store graphic information, so as to develop the information capacity of the letterbox. Based on the access control system of the residential area, the invention designs an online picture-text mailbox system by applying the embedded system and bluetooth technology, so that the mailbox has the function of detecting whether there is a letter. The system also has the function of receiving and storing pictures and texts, and the property can transmit prompt information through the access control network. Residents can check whether there are letters in the mailbox at any time without leaving home, and can also download graphic information.

In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical effects, the present invention is realized through the following technical solutions: an online message box system, including a property center, an access controller and an indoor unit, and the access controller communicates with all The property center is connected with the indoor unit, including a newspaper box manager, the newspaper box manager is connected with the access control controller through the access control network, the newspaper box manager includes a single chip with MCF52223 as the core, the One side of the single chip is connected with an incoming piece detection circuit, an SD card system and a serial communication interface circuit, and the other side of the single chip is connected with a USB interface, a peripheral circuit and a power supply circuit.

Further, it includes an indoor controller, the indoor controller is connected to the indoor unit through a Bluetooth communication interface, and a Bluetooth module BF10 is embedded in the Bluetooth communication interface, and the Bluetooth module BF10 is connected to the indoor controller through Bluetooth .

Further, the Bluetooth module BF10 is provided with a first sending pin and a first receiving pin, and the first sending pin and the first receiving pin are respectively connected to the second receiving pin of the serial port of the indoor unit. pin and the second sending pin, the bluetooth module BF10 also has a third pin for bluetooth receiving and sending interrupt requests.

The principle of the present invention is: the system includes two parts, the newspaper box manager and the indoor controller, and the two parts are connected through the access control network. The newspaper box manager detects whether there are newspapers in the newspaper box, and receives the prompt information sent by the property through the access control network; the indoor controller is a mobile phone that can be redeveloped, and accesses the access control network through the access control Bluetooth, and then browses the mail arrival information and prompt information.

The manager is based on Freescale's 32-bit MCF52223, which expands the infrared detection circuit, SD card storage system, serial communication interface, USB interface and basic peripheral circuits and power supply circuits. The infrared detection circuit is a pair of infrared emitting and receiving diodes, and a pair is installed in each newspaper box to detect whether there are newspapers in the newspaper box; the SD card storage system is divided into public storage space and user storage space for users to browse and download; management The device is connected to the access control controller through the serial communication interface and then connected to the access control network.

The Bluetooth communication interface of the indoor unit is realized by embedding the Bluetooth module BF10. BF10 is a Bluetooth module with a 3.3V power supply and a serial communication interface. The system design BF10 is connected to the access control indoor unit through the serial port, so that the indoor unit has the Bluetooth communication function conveniently. In the access circuit of BF10, pins 1 and 2 are the serial communication sending and receiving pins of the Bluetooth module, connected to the indoor unit serial port receiving and sending pins (MCU_RX, MCU_TX), and pin 24 is the Bluetooth receiving and sending interrupt request.

The indoor controller adopts Huayu P1300. Huayu P1300 is a mobile phone that can be redeveloped. Through Java program design, design the basic browsing newspaper application. By setting the paired Bluetooth address with the indoor unit, you can browse the mailbox, including checking whether there are letters and downloading prompt information.

The beneficial effects of the present invention are:

1. The invention enables residents to detect whether there are letters in the mailbox at any time without leaving home, thereby avoiding delays in letters and reports;

2. The invention enables the mailbox to have the ability to receive and store graphic information, thereby developing the information capacity of the mailbox;

3. The invention enables the traditional mailbox to have the function of detecting whether there is a letter, as well as the function of exchanging graphic and text information, which enriches the functions of the traditional mailbox;

4. This invention also expands the content of property service items, and provides a new way for targeted information delivery.
