Home Automation , Building Management eHouse – Decoding the status of microprocessor controllers
Home Automation received by the control panel connected to the LAN or WiFi , via UDP (User Datagram Protocol) .
The standard frame reception status in binary form , with Controllers was discussed in the article ” Intelligent Building eHouse controller status package” .
Decoding the frame needs to analyze every bit of data from pack.
In addition, each type of controller:
- RoomManager
- ExternalManager
- HeatManager
- InputExtender
- CommManager
- LevelManager
- EthernetRoomManager
Have a difference in amount of digital inputs , measurement inputs, digital outputs , dimmers , monitoring functions and algorithms that result , that the data in the standard frame mutate depending on the type of controller.
This results in the need for decoding the 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 the frame decoding algorithm may take up to 1 month .
To minimize this time to a minimum , to facilitate ready to present the algorithm borrowed from eHouse.exe application, to automatically decode all the information from the controller and load data into the template records of touch panel (for tablets) Windows XP , Vista , 7 , 8 .
After automatically loading the data into the eHouse software libraries , with a few lines of code, you can create your own control algorithms eHouse system in a few minutes.
Binary Frame decoding software of the eHouse status standard is implemented in template library for panel. It needs to be done binary, for direct decoding status from Ethernet controllers without eHouse.Exe application supervision.
Decoding the entire frame (for microprocessor controllers eHouse1 RM , EM , HM) is carried out by the procedure set_rm function(str:array_of_char;TCP_INDEX_INC:integer);
parameters are functions of the buffer status and shift (offset) . The buffer contains all the received data from the status . Offset depends on the type of transmission (extended address , normal , and other future applications dependent on communication algorithms) .
It automatically fills the array status for each controller individually and can then directly manipulate the data or update data automatically on screen touch panels .
This function is activated in event procedure of receive data from UDP socket component (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 ;
MyStream:TMemoryStream ;
begin
if filesystem_status then exit ; // If no file system filesystem_status
MyStream:=TMemoryStream.Create; // Create a stream of data
binary.ReadStream (MyStream); // Read the data stream
MyStream.Read(C[0],NumberBytes); // Loads the buffer C
set_rm(C,1);// Converts the binary data and loads the registers rm [index] for controllers eHouse 1
Test_save; // Test record the output to a text file for easy operation
update_panel; // Load data for the control panel
end;
It allows you to automatically and non-invasive collection of data over a LAN or Wi-Fi with the package broadcast via UDP (User Datagram Protocol) .
What more does not require an open connection to the server only listens on the port broadcast ‘6789’ default or other.
Errors link , Network , routers do not result in a suspension or unspecified software errors (as in the case of communication with TCP server) , but disappears just update the data without affecting the data or suitable server UDP client application.
WARNING! . If you create control software on a Windows for eHouse Home Automation, it is necessary to implement all algorithms in one application, which analyzes the data and performs all the algorithms and visualize them. We observed sometimes that 2 UDP listener socket can not exist on the same PC.
