Description

The automatic counting and counting system increases the speed of meetings, conventions, meetings, etc., ensures accuracy of counting, eliminates the possibility of errors and reduces the time spent on counting.

Until now, mechanical or electromechanical vote counting systems have been used.

By the principle of operation, the mechanical counting system is divided into two main groups: single-stage and multi-stage.

The one-step system consists in the accumulation of impulses directly at an individual place and collecting them with the help of searchers, who alternately bypass all places. This system can be applied only with a small capacity of the hall, as it requires a relatively long time to count.

Most of the existing vote counting systems are built on a multistage principle.

The essence of the multistage principle is the preliminary accumulation of pulses on special accumulators and the final counting by means of; seekers and mechanical counters.

Multistep systems provide a higher counting rate than single-stage systems, but have a number of significant drawbacks:

1. It is necessary to have a large number of relays with the use of at least two normal or one two-winding relay per subscriber. Apart from the fact that the power supply of the relay will require a considerable expenditure of energy, due to the large number of mechanical contacts with all its inherent flaws (sticking, contamination, breakage, etc.), the operation of such a system is expensive, its operation is not stable enough and requires constant monitor the adjustment of the relay contacts.

2. The cumbersome construction of counting steps (delegate location-linear relay-linear finders - counters drives-finders drives-fixation results) also extremely complicates its maintenance.

The subject of the Haciojimero invention is a device for automatic counting of votes in conference rooms with the installation of contact switches at delegate places and step finders alternately connecting individual contact circuits to electrical counting mechanisms, taking into account the total number of closed contacts by the number of incoming pulses. The proposed device is distinguished by using a number of capacitors, according to the number of delegate places, pre-charged from current sources and alternately connected to the anode circuit of the thyratron with one of the groups of contacts of the step finder, the contacts of the second group serve to simultaneously connect the corresponding contact at the delegate’s place Thus, when this contact is closed, the thyratron was ignited, causing the discharge of one of the capacitors to the counting circuit.

The invention is illustrated in the drawing; in FIG. 1 which shows the complete diagram of the device, and FIG. 2 is a variant of switching on a delegate seat with an acknowledgment lamp.

The proposed counting device has the following sequence of steps:

1. A Delegate seat equipped with a voting kit consisting of a button, a sliding contact, an equalizing resistance, and a confirmation lamp.

2. Satellite (allocated station for 1000 delegate seats) equipped with a device for removing pulses from the delegate seats and for blocking the voting sets.

3. Storage located at the central station and representing a lamp (three-way) gfybor.

4. Summer consisting of three two-field finders and a lamp set similar to a drive.

5. Digital indicator - mechanical type (the latter can be made in the form of optical

signal or on any other principle).

After pressing the button KP, which supplies plus to the contactor Ki and the time relay Rv, the satellite seeker motor is switched on, the brushes of which, moving along the contacts, charge the capacitors of the delegate places (from GI to Xyooo) - Through. after the motor is turned on, the time relay Rv is triggered, the charge value is torn, and this turns on the lamp device for charging capacitors. The system is ready for action.

When pressed by the delegate, the copier, the second-floor seeker brush, moving synchronously with the first, will not apply a compensating negative displacement to the grid of the thyratron, which will operate and discharge the capacitor connected to its anode with the first-floor brush.

Thus, all delegates pressing the buttons will discharge their capacitors, the current pulses of which with resistance are assigned to the drive. Discharged conmers. Cannot re-participate in this tour. Unpowered capacitors are systematically charged with a double brush, slipping it into the first field.

At the moment when the brush is on the contact of a charged capacitor, a current locks the lamp JL through the resistance Re. In the case of the thyratron L, it remains open and a capacitor is charged through the second half of the brush.

At the moment when the brush is located on the n, l contact of the discharged capacitor through the resistance Re-; no current and podzar yes does not occur.

The implementation of the device is provided in two versions. The first variant is without a kkvtiro1 ani lamp and the second variant is with a lamp, without a lamp, and the neon one was taken as the last one (Fig. 2).

To the satellite finder is added one field with a brush moving synchronously with a charging brush. Before voting at the charge of delegate capacitors, a brush of the third floor simultaneously charges the handshake consensator and is applied to the resistance. During the time of brushing around all the capacitors of this satellite, an incomplete discharge of the checkout capacitor to the lamina occurs, but the return of the brush to the integral contact resumes its charge, lighted up: until the moment of voice giving, the lamp is on all the time. Capacitance of the handshake capacitor takes place through the thyratron charging the delegate capacitors. When the delegate pushes the button and the delegate capacitor discharges as a result of this, the handshake light goes out, because the thyratron supplying its capacitor will be locked when the brush is on this contact due to the discharge of the delegate capacitor.

The impulses from the satellite are fed to the drive, which is a three-stage lamp device.

First of all, the first cascade tiratrons, which count the units, connect: so that the impulse voltage arrives i :: e is applied simultaneously to all MX grids, but only the first n; -i they can react to it, the GIC like the others have on the nets blocking negative mixing, do not let them trigger. Ignition of the first rioKB world doesn’t continuously prepare the next one by submitting a positive potential of the first potential to its grid, compensating for a negative bias. In a similar way, the operation of all the next tiratrons of the cascade occurs, and the start of each subsequent tiratron suppresses the previous one during the Pomondi voltage supplied from it through the capacitor to the cathode of the previous tiratron. The last (tenth) thyratron of the first cascade gives impulse to the second cascade, which counts the tens, and at the same time the previous thyratron goes out, prepares

to receive a pulse, the first thyratron, and the cycle begins anew.

The second and third cascades work similarly to the first. After the arrival of the last pulse, each stage will remain lit for one thyratron, indicating and fixing the quantity; pulses received by each cascade.

The advantage of this system over the mechanical one is that all switchings take place purely electrically without the aid of mechanical relays, which makes it possible to achieve high speeds. This system can count the pulses received by B in an amount of 3000 4000 pieces per second.

Registered on each: The drive of the number of pulses is taken and summed with a collector and an adder.

The collector consists of three pairs of brushes mounted on an axis and constantly flipping in the field of contact. The rotation comes from a motor that is switched on simultaneously with the launch of satellite using KOiiTaKTOpa K ... Each pair of brushes collects impulses from the same cascade of all satolites, and the order of switching on is sequential (after walking around its floor with units it turns on the chain of the grid of tens and then the chain of hundreds of brushes ). Switching of the chains of the brushes takes place using three relays P. -P ;;, P .; with four pairs of contacts. Each relay can turn on ;; it is only when the brush is at the zero contact that the first relay is switched on is produced by the hphemeium relay., triggered through: -; 1-2 seconds after pressing the chair, nycKOBOi button KP.

The resistance of TiHe is included in the cathode circuit of each cascade of the collector. from which an offset is applied to the lamp grid. If at least about 1IN tiratron is lit in the cascade, then the Letts is unlocked and one of the brushes removes the voltage (impulses) from the contacts of the seeker field; A friend's brush, moving across an adjacent field in sync with the first one, sends a field and capacitors to a tipping voltage across the cathode of each thyratron through the contacts. At the moment of its passage through the contact of a burning thyratron pulse, it extinguishes it through a brush and thereby closes the lamp of the collector. Thus, with further movement of the first brush across the field of the cascade of pulses no longer arrives. All cascades of storage units are brought to the first field, consisting of twenty five sections with ten contacts. Similarly, there is a collection of pulses from the cascades of tens and hundreds.

From the collectors, the pulses go to a picascade adder, working on the above described principle / accumulator. The fixed total number of votes cast is taken by means of a counter with five fields, which, showing the result of the counting; , can, with the help of a sandwich adapter, fix it also on paper.

Each voting stage can be recorded on a separate counter.

The preparation of the system for the next round is made by re-pressing the start button.

Counting those present and working; ps by pressing the KOj button, and the system works in the same way as described above by sitting in a seat.

The sequence of operation of the device is as follows.

The chairman announces the start of voting and simultaneously presses the start button. Neo-new bulbs are lit on the delegate seats, indicating that the sistemgy is working and inviting delegates to vote.

After the delegate presses the button (and discharges its capacitor), the light goes out, indicating that the voice is received |

After 2 seconds After the chairman of the announcement of the start of the counting of votes and turning on the CP.2 key, the iifis control panel will show the result of the counting, which can be transmitted to the light display or announced via the notification network.

If necessary, make a count of those present, the chairman presses the counting button and after 2 seconds. gets the result.

The described scheme gives a general idea of the principle of operation of the proposed system of votes, built on the use of ion devices. In the description, only the principal provisions necessary for the analysis of the action of the device are given. All auxiliary circuits and non-primary positions are not listed here.

The proposed device provides the following indicators:

1. A quick tally of the voting results, which is very significant, is meaningful for meetings with a large number of delegates.

2. Because of the small capital expenditures during construction and the small number of devices, it is the most economical system.

3. Has no less reliable operation as compared with electromechanical systems, and even higher in a number of links.

4. It will require less space to place the equipment than electromechanical systems, and significantly less personnel.
