Description

FIELD OF TECHNOLOGY

The present technical solution relates to a method for setting up an intercom network and receiving data from an intercom network via a Bluetooth module.

LEVEL OF TECHNOLOGY

From the information source RU 2706620 C2, published on 11/19/2019, there is a known method of providing controlled access for visitors to the building. According to this method, the visitor's mobile device entry identification information is initially provided when the mobile device is in the vicinity of the building entrance. The mobile device then sends login credentials to the remote server. In response, the server sends the building's occupant list information to the mobile device based on the login credentials, and the mobile device presents the occupant list to the visitor. The visitor then selects a resident from the list, and then establishes a connection between the mobile device and the remote device associated with the selected resident. Finally, the access granting information is provided to an access control device configured to control a visitor's access to a building through an entrance. The solution is aimed at providing controlled access for visitors to the building.

DETAILED DESCRIPTION OF THE INVENTION

In the following detailed description of an implementation of the invention, numerous implementation details are set forth in order to provide a thorough understanding of the present invention. However, it will be obvious to those skilled in the art how the present invention can be used, with or without these implementation details. In other instances, well-known techniques, procedures, and components have not been described in detail so as not to obscure the details of the present invention.

In addition, it will be clear from the above description that the invention is not limited to the above implementation. Numerous possible modifications, alterations, variations and substitutions, while retaining the spirit and form of the present invention, will be apparent to those skilled in the art.

The intercom system board includes STM32 microprocessor, memory module, Bluetooth LE (Low Energy) module. The proposed method for controlling an intercom network can operate in at least one of the modes:

door opening mode by means of a paired device;

mode for switching the intercom into the mode of adding a new device or into the mode for configuring and reading the current settings of the intercom;

the mode of adding a new device;

mode for reading the current doorphone settings and setting new doorphone settings, in which the paired device sends a request to the doorphone.

A paired device means any portable device that has a Bluetooth module and is paired with the doorphone via a Bluetooth wireless network. A portable device that has a Bluetooth module can be, but is not limited to, a smartphone, tablet, smart watch, etc.

FIG. 1 illustrates the interaction of the intercom panel with paired devices and the server in different modes of operation, where A is the intercom panel with a built-in BLE Bluetooth 4.0 module. B - the person who configures the intercom and maintains its operability (engineer) through a mobile application installed on a device with Bluetooth function (smartphone, tablet, smart watch, etc.), C - a server that processes data and on which virtual copies with the current settings of all intercoms, D - a user with a paired device that has a Bluetooth function (smartphone, tablet, smart watch, etc.), E - a third party with a device that has a Bluetooth function (smartphone, tablet, smart watch, etc.) etc.), but not connected to the doorphone panel.

The door opening mode by means of a paired device (basic mode) is used by users with already paired devices (D) with the intercom panel (A). With a sufficiently close approach of the user (no further than 2 meters from the intercom) with the paired device, the door to the staircase opens and remains open for 5 seconds. If the user (E) wants to connect to the intercom via Bluetooth, but he is not in the list of users on the server, his request is rejected.

From the main mode, you can switch to the mode of transferring the doorphone to the mode of adding a new device or to the mode for configuring and reading the current settings of the doorphone, i.e. waiting for the key by entering the password on the intercom panel.

In the materials of this application, the password is a code starting with 0 and any number from 1 to 9.

The key standby mode is used to switch the panel either to the mode of adding a new device, or to the mode for reading the current doorphone settings and setting the new doorphone settings. In this mode, for some configurable time, the panel is available for connection to unpaired devices. The panel transitions from the main mode to the standby modes for the key and adding a new device are carried out after authentication (entering the password). In this case, when switching to any mode, it is necessary to re-authenticate. If the authentication is positive, the panel is disconnected from the current connection and goes into the mode of adding a new tenant. In this mode, it is possible to pair with a previously unpaired device.

After connecting, you need to send a password to the panel, which is a combination of numbers. Each mode has its own password, which is entered directly on the intercom panel. The engineer receives the necessary passwords to switch the panel to the required mode through the application on the mobile device. To connect to the panel, the engineer uses a Bluetooth enabled device.

If the key matches the key for adding a new device, the panel will switch to the mode of adding a new device; if the key is incorrect, the panel will turn off and switch to the main mode. The function of binding a new device, by the users themselves (D) in the application on a mobile device, can be implemented through the API.

If the key matches the key for configuring and reading the current doorphone settings, the panel will automatically switch to the mode for configuring and reading the current doorphone settings, if the key is incorrect, the panel will turn off and switch to the main mode.

The add new device mode is used to pair with devices (smartphones, tablets, smart watches, etc. with Bluetooth function) that have not been paired before. After entering the password for adding a new tenant, the panel will automatically disconnect from the engineer device (B). After that, the new tenant (D) will need to reconnect to the panel, and she will offer him to pair. After that, the panel will switch to the main mode.

Mode for configuring and receiving (reading) the current settings of the intercom.

The engineer (B), who has a password for connecting to the intercom panel, to configure and read the current intercom settings, connects to the intercom panel on the paired device with Bluetooth function (smartphone) and enters the password to enter the setup and receive (read) mode current doorphone settings.

All operations for reading the current settings and entering new settings are carried out in the application on the mobile device.

The engineer (B), through the mobile application, sends a “get” request to the intercom panel (A), through the Bluetooth module of the intercom panel, the request is sent to the STM32 microprocessor. Panel (A) reads the current intercom settings and relays the data to the server (C). Server (C) processes the received information, decodes and sends the Engineer (B) to the mobile application the current settings on the server (C) and the intercom (B), as well as the status of their synchronization. The information received is processed as follows. Data from the STM32 processor from the intercom panel is sent in binary form. Further, on the server, the binary form is converted into text.

The server stores digital copies of all panels, due to which, if changes were made to the panel settings on the server at a time when the panel was unavailable, then the next time the panel is connected, the panel is synchronized with the server, receives and applies the settings sent from the server.

To change or add primary settings, the Engineer (B) makes a “post” request in the mobile application. Engineer (B) enters new settings and generates a JSON file that is sent to the server (C). The JSON file contains the following fields: request id (number of the current request for correct logging of operations), ip address of the intercom panel, gateway, subnet mask, DNS ip, mac address.

The get and post requests contain the following information:

- the range of apartments or offices in the building;

- serial number of the panel;

- ip-address;

- gateway;

- subnet mask;

- DNS IP;

- mac address.

On the server (C), the necessary settings are converted into a binary file. Further, the server (C) relays to the Bluetooth module of the intercom panel, through the application on the Engineer's mobile device (B), the file with the settings in a binary format. The received file on the intercom is processed by the STM32 intercom panel microprocessor and is written into the intercom memory.

In the modern world of devices broadcasting Bluetooth signals, there are many and there is a possibility that during the sending of the “post” request, a parallel connection to the Bluetooth-module by a third device (E) will occur. To exclude the possibility of third parties connecting to the Bluetooth-module of the doorphone panel, during the sending of the “post” request, the doorphone configuration algorithm provides for a duplicate “patch” request. Engineer (B), through a mobile application, in the body of the “patch” request duplicates the JSON structure that was sent in the body of the “post” request. In response, the server confirms the success of saving the changes in the intercom and on the server.

On the server (C), a virtual copy is created for each activated intercom panel. During all operating modes, all changes and settings of the doorphone panel (A) are synchronized with a virtual copy of the doorphone panel (A) on the server (C). Thanks to this, the service company has data on the settings of all panels.

During all operating modes, all events that pass through the Bluetooth-module of the intercom panel are logged on the server (C).
