Abstract

MICROCONTROL SWITCH SYSTEM for controlling and monitoring up to 100 groups with 100 lighting points with only 3 wires. The microcontrolled switch system is composed of two circuit formed by 02 interconnected double-sided plates called circuit breaker and another circuit composed by a double-sided plate called terminal circuit. For this system to work it requires only 5 wires for each lighting point. The logical operation of the system is characterized by the logical communication between the program recorded in the terminal circuit microprocessor and the terminal circuit program through a wire for data communication.

Description

"MICROCONTROL SWITCH SYSTEM" This patent application relates to two microcontrolled electronic circuits for controlling 100 groups with 100 lighting points each, with monitoring using 3 flos and 4 buttons. One of these circuits is called a circuit breaker consisting of two double-sided boards interconnected by DB9 connectors. These will perform the function of the switch using a microcontroller and two binary to decimal converter (BCD) integrated circuits, the other termed as a terminal consisting of a double-sided board that will perform the interfacing function of the illumination point. Each illumination point will have a terminal circuit.

Currently the switches are single, parallel and intermediate, but neither switch can control at least 100 independent points with only 3 wires. The electronic system consisting of two microcontrolled electronic circuits uses 3 wires, one wire intended for positive use of the power supply, one negative of this and the other of data communication between the two microcontrollers involved in the system and 4 buttons being one button. forward address, one button for back address, one button updates and another button chooses group. The circuit breaker identifies and addresses each illumination point as a unique and different number from the others, interacting with each illumination point through these identification numbers, using only one data communication wire rather than using a separate return wire for each. point as it is used in the current switch system. 05 The PIC16F628 microcontroller will be programmed and recorded with the MPLAB programming environment (IDE) in conjunction with a commercially available microcontroller-specific recording device for this project to record it via the MPLAB programming environment. The C language source code of the circuit breaker microcontroller is shown below: #include <16F628.h> #use delay (clock = 4000000)

The source code of the terminal circuit will contain in the group variable and the address variable the identification value that will differentiate the corresponding point in the system and will be programmed in C language. The source code of the following terminal circuit microcontroller is an example for point 22 of the group 100 and is shown below: #include <16F628.h>

#use delay (clock = 4000000) #fuses

INTRCJO1NOWDT, PUT1NOBROWNOUT, NOMCLR, NOLVP, NOPROTECT #use

rs232 (baud = 19200, parity = N, xm it = PI N_A2, rcv = PINA1, stream = verify) main () {

int address, relay, group, function, status; address = 0; 05 rel = 1;

group = 0;

output_low (PIN_B0);

while (true) {

group = fgetc (check);

address = fgetc (verify); function = fgetc (check);

if (group == 100 && address == 22 && function == 100) {

if (! reread)

{

output_low (PIN_B0); rele = 1;

}

else

output_high (PIN_BO); rele = 0;

}

if (group == 100 && address == 22 && stealth == 101) {status = input (PIN_A3); delay_ms (10); fputc (status, check);

}

}

To use this system to control a number of less than 100 points or to prevent the system from stalling, we must program one of the terminals with the following source code with a small addition of code. The following source code is for group 100 point 0 control and monitoring and is shown below: #include <16F628.h> #use delay (clock = 4000000) #fuses INTRCJO,

Claims (9)

CLAIM 1. "MICROCONTROLLED SWITCH SYSTEM" of the present invention refers to a microprocessor circuit with switch function and another microcontrolled circuit with terminal function for independent control and monitoring of up to 100 groups with 100 lighting points, with only 3 wires instead. return wires for each illumination point. The logic operation of these circuits is characterized by the communication of two microcontrollers following the instructions of two respective programs already described in the descriptive report. Figure 1 is an example of this system for controlling three illumination points. In this figure, the circuit breaker (31) allows the selection of the illumination points by the address advance or return address buttons (36) and (37) interfaced by the terminal circuits (32), (33) or (34) and shown display ( 43) thanks to the use of the microcontroller in conjunction with the binary to decimal conversion integrated circuit (BCD); The LED (44) indicates whether the selected point is lit or not. Once selected, if the update button (38) is pressed, the circuit breaker will send a group identification code to the terminal circuits and shortly thereafter will send another selected point identification code and then a point status update code. illumination via the data wire (42), reversing the electric state of the lamp of the selected point. The power supply (35) provides continuous voltage to the system by connecting the positive on wire (40) and the negative on wire (41). Button 39 is the group selection button, when pressed will make the selected group the group indicated on the display. Figure 2A represents one of the faces of the first double-sided plate of the dark-traced switch circuit and the opposite face of this plate is shown with light-colored traces. The same opposite face that is shown with light strokes in Figure 2A can be seen with dark strokes in Figure 3A, because Figures 2A and 3A represent the same plate, but opposite sides, the same for Figures 2B and 3 B, 4 A and 4 Β. The microcontroller (11) works in conjunction with the binary to decimal converter integrated circuits (12) and (16) to display the selected illumination point number on the 7 segment display that will be installed in the hole (13). The DB9 connectors (14) and (15) of Figures 2A and 3A are of the weldable plate type and connection angle equal to 180 degrees, being male and female respectively and to be connected with the DB9 connectors (18) and (17) which are also of the weld type plate and female and male respectively with connection angle also of 180 degrees located on the second circuit of the circuit breaker shown in figures 2 B and 3 B. In figure 4 A, the relay (19) it activates the illumination point lamp, controlled by the microcontroller of this board (20) and monitored with the help of the voltage comparator integrated circuit (21).
