eHouse Smart Home – Decoding Binary Status

Decoding the binary status of the drivers smart home – source code

Smart Home , intelligent Building eHouse – Decoding the status of microprocessor controllers
Home Automation , Building Automation received by the control panels working on the LAN or WiFi , the UDP ( User Datagram Protocol) .

The standard frame reception status in binary form , with microprocessor controllers
Decoding the frame requires analyzing each bit of data from separate . In addition, each driver type :

  • RoomManager
  • ExternalManager
  • HeatManager
  • InputExtender
  • CommManager
  • LevelManager
  • EthernetRoomManager

It has a difference in the amount of digital inputs , measurement , digital outputs , dimmers , monitoring features and algorithms which cause , that the mutate in a standard frame according to the type of driver .

This necessitates the decoding bit by bit for each type of controller independently . In the case of the implementation of all types of microprocessor controllers to create and test an algorithm decoding the frame can take up to 1 month .

To minimize the time to a minimum, to facilitate ready to present an algorithm borrowed from an application ehouse.exe , enabling automatic decoding of all information from the driver and load data into the template registers the touch panel ( for PADs ) Windows XP , Vista , 7 , 8. After automatically loading the data into the eHouse software libraries , with the help of a few lines of code you can create your own control algorithms running eHouse.

The standard template software panels should make the library “binary” , which is a full frame decoding of a binary status .

Decoding the entire frame ( for microprocessor controllers eHouse1 RM , EM , HM ) is realized by the function procedure set_rm(p:array of char ;TCP_INDEX_INC:integer);

function parameters are buffer status and shift (offset ) . The buffer contains all the data received from the status.
The offset depends on the type of transmission (extended address , normal , and other future applications dependent on algorithms and communication).

It automatically populates the array status for each driver individually and can then directly manipulate the data or automatically update the data on the screen, touch panels.

This function is activated in the procedure of receiving data from the component UDP ( TNMUDP – called binary) in the event onDataReceived .

The reception is as follows:

procedure TForm1 . binaryDataReceived (Sender: TComponent ;
NumberBytes : Integer ;
FromIP : String ;
Port : Integer );
var C : array [0..1024 ] of char ;
Mystree : TMemoryStream ;

begin
if filesystem_status then exit ; // if not by the file system filesystem_status
Mystree : = TMemoryStream.create ; // creates a data stream
binary.ReadStream(Mystree); // reads the data stream
Mystree.Read (C[0],NumberBytes); // loads into buffer C
set_rm(C,1); // Processes binary data and loads the registers rm [index ] for drivers eHouse 1
Test_save ; // Test record the output to a text file for ease of operation
update_panel ; // Loading data for the control panel
end ;

Allows for automatic and non-invasive receiving data via LAN or WiFi using UDP broadcasts packets ( User Datagram Protocol).
What more does not require connecting to the server and only listens on port broadcast ‘6789’ default or other .

errors link , network , routers will not result in a suspension of software or indeterminate error (as in the case of communication with TCP servers ) , but disappears only update the data without affecting the sending server or client application data UDP.

NOTE !! . When you create the control software on a Windows server system eHouse , it is necessary to implement all the algorithms in one application , which analyzes the data and performs all the algorithms, and it visualizes .

Significant variables in the library binary :

// 3 – fire on = > yellow level – histeressis > Temp jacket > yellow level + histeressis ) (green + yellow leds ) – green – yellow
// 4 – fire on = > yellow level + histeressis > Temp jacket > red level – histeressis ( yellow) – yellow
