Abstract

The present order speaks of an original supervisory system of integral count (SSIC), which aims individuals and objects counting inside determined places, based on specific areas, through count spots, which permits general and area countings, by the means of connection to a local supervisory system. Totally modular, it fits either industrial (parts fluxion) or commercial (individuals fluxion) environments. In general, the system is compounded by a (CT) Count Transmitter (1), Emission Assemblage (2), Receiver Assemblage (3), (SULC) Supervisory Unit of Local Count (4), (SSIC) Supervisory System of Integral Count (5), and the general diagram (6).

COUNT TRANSMITTER - (CT) The conception of "SSIC'was only possible because of the development of the "COUNT TRANSMITTER - (CT)" "CT" is the system's most important component It aims transmit fast and efficiently the "fluxion direction" of an object or subject passing through an specific spot It's important to clarify that it only registers (transmits) the "fluxion direction" entrance (increasing) - exit (decreasing) and not quantities We could make use of transmission for quantities, but in order to simplify the "CT'project and consequently reduce costs we have made use of transmission for "fluxion direction"

CONNECTIVE DIAGRAM AND FUNCTIONAL CHARACTERISTICS In picture no.1 we can see the count transmitter's ("CT') entire connective diagram, which is compounded by two distinctive assemblages The EMISSION ASSEMBLAGE (picture no.2), that is responsible for the generation of two constant active parallel X-ray beams, beam A and beam B, which received respectively the following names: increasing beam and decreasing beam. The description of the internal assemblages:

(Al) - Eletric Supply:

Wire entrance - way for energy supply. 110V/60Hz options available.

(B1) - Supply Source:

Circuitry responsible for rectification and regulation of entry voltage. Adaptation is necessary for keeping the system work conditions.

(C1) - Decreasing Occilator:

Circuitry responsible for generation of frequency for the decreasing infra-red ray beam (beam B).

(D1) - Increasing Occilator: Circuitry responsible for generation of frequency for the increasing infra-red ray beam (beam A).

(E1) - Decreasing Amplifier:

Circuitry responsible for the power sign rising of the decreasing occilator circuitry assemblage (beam B) (F1) - Increasing Amplifier:

Circuitry responsible for the power sign rising of the increasing occilator circuitry assemblage (beam A)

(G1) - Infra-red ("IR") Decreasing Emitter

Circuitry responsible for the increasing infra-red beam generation itself in modulated condition (beam A)

This circuitry is basically compounded by special Leds responsable for infra-red ray emission.

The RECEIVER ASSEMBLAGE (picture no.3) is responsable for the beams reception, direction processing and its following transmission. Description of the internal assemblage:

(A2) - Decreasing Direction Receiver (DDR):

Circuitry responsible for the decreasing infra-red beam reception itself in modulated condition (beam B). This circuitry is basically compounded by a photo transistor projected to work inside infra-red spectrum

(B2) - Increasing Direction Receiver (IDR)

Circuitry responsible for the increasing infra-red ray beam reception itself in modulated condition (beam A)

This circuitry is basically compounded by a photo transistor projected to work inside infra-red ray spectrum

(C2) - Direction Logical Module

It is the count transmitter's "brain" It is the one that identifies which infra-red ray beam has firstly been interrupted, so generating its corresponding signal

(D2) - Transmission Module

Circuitry responsible for signal transmission, "two-wire" The signal is transmitted in a 4 to 20mA current band, where the same pair of wires conducts the 24Vcc suplly to the transmitter The CT's functioning principle is quite simple, being physically installed at objects and people passage-way area and respecting the entrance fluxion We can affirm that wether beam-A (increasing) is interrupted first in relation to beam-B (decreasing) we can be sure the object or individual is entenng the area and, the same way, wether beam-B is interrupted first we can be sure the object or individual is leaving the area

The information transmission coming from the count transmitter is based on the

"two-wire connection", often used in industπes, i e , either the transmitter receives the eletπc supply (+24, grounded) or the same pair of wires allows the information transmission inside a 4 to 20 ampere band Such information is coded like this

TRANSMISSION FLUXION DIRECTION

20 (mA) (+1) - increasing

12 (mA) (0) - no flux

4 (mA) (-1) - decreasing

Every time the transmitted signal vanes from 4 mA to 12 mA, we can affirm that there is a person or object leaving the area

Every time the transmitted signal vanes from 20 mA to 12 mA, we can affirm there is nobody entering the area Every time the transmitted signal stays stable on 12 mA, we can affirm there is nobody entering or leaving the area

SUPERVISORY UNIT OF LOCAL COUNT (SULC)

The Cts themselves do not have the capacity of processing the count; they need to be connected to a "Supervisory Unity of Local Count - SULC", which can register every signal coming from the Cts and then process the count

After the count is processed, it is sent through a telephone to the "SSIC", which stores and register all the other SULC's counts (picture no 4)

CONNECTIVE DIAGRAM AND FUNCTIONAL CHARACTERISTICS (A3) - Treating Module and Signal Filtration

Circuitry responsible for the connection of transmitters to SULC As the main aims we have the generation of 24 Vcc supply to the transmitters, the filtration of possible transmission noises, and the convertion of the analogic signal from 4-

20 mA to the analogic signal of 1-5 Vcc (through a 250 Ohm resistor) And fundamentally the interpretation of the fluxion direction, transforming it in an increasing or decreasing signal according to the codification previosly descnbed

It aims offer a safe interface either of entrance or exit signals for transmission of objetcts and individuals quantities via MODEM, previously processed by the system And the convertion of the 1-5 Vcc analogic signal (originated from the

Multiplexation Module - B3) in digital signal, through A/D converters

"SULC" program-related, which allows either a correct acquisition and data control coming from the Cts or an excellent Man/Machine interface performance, offering all the view of individuals/objects quantities of inspected areas through "MENUS", as well as its phone transmission to the "SSIC" . SUPERVISORY SYSTEM OF INTEGRAL COUNT

The system is completed through the connecting the "SULCs" with the "Supervisory System of Integral Counfvia telephone through a MODEM. The aim is to manage and store every "SULC" count so generatin reports and predictions the number of individuals, through grafics and tables (picture no.5). For example: A departament store with a head-office and some branches. We can generate the following reports:

1) Per department/branch : Total of people inside each department inside and specific branch or in all the branches.

2) Per branch : Total of people inside each branch. 3) Tendencies : Prediction per (period/day/month/year) of total of people inside each department of an specific branch or in all branches.

ACQUISITION, CONTROL AND PROCESSING OF COUNTS

(PRO-CONT)

* PRO-CONT/L:

"SULC" program-related (Supervisory Unit of Local Count) for acquisition, control and processing of count coming from "Cts" (Count Transmitters)

^* PRO-CONT/I:

"SSIC" program-related (Supervisory System of Integral Count) for acquisition, control and processing of count coming from "SULC"(Supervisory Unit of Local Count). CONCLUSIONS:

As we could observe at (picture no.6), the system is completely modular allowing "Cts"and "SULCs" aditional improvements. The cycle of data acquisition is also very simple:

1) First: II "fluxion directions" are registered by the "Cts"and transmitted to the "SULC'of a determined supervised area.

2) Second: The "SULC'then interprets it and transforms it into counts, which shall be restricted or general areas.

3) Third: After this process all counts are sent through a phone (MODEM) from the "SULCs'to the "SSIC". 4) Fourth: Reaching the "SSIC'the counts are set apart per "SULCs" and per department for following emission of reports and tables.
