SU45857A1 - Automatic distress alert radio transmitter - Google Patents

Description

It is known that the established distress signal is composed as follows: the SOS signal is repeated three times and then the longitude and latitude are given in degrees and minutes, finally the call sign of the vessel in danger is repeated twice.

The present invention relates to a device for an automatic radio transmitter of distress signals, and any person who does not even know the signs of Morse code can pre-compose the transmitted signal.

In FIG. 1 schematically depicts the proposed radio transmitter; FIG. 2-detail implementation of the contact drum transmitter.

The radio transmitter consists of five parts:

1) Swiss switch I (Fig. 1)

2) contact drum T. 3) IND Poses

4) SOS disk

5) BA distributor. Swiss switch K (Fig. 1)

used for pre-dialing on the radio position transmitter

or the aircraft sending the signal. It consists of ten plates from to Ng, corresponding to figures from O to 9. Perpendicular to these plates are installed nine plates from R to, equipped with each slider C, whose contacts touch plates of the horizontal row (as shown in Fig. 1 left). The plate corresponds to hundreds of meters, the plate / j-decks, the plate / 3-units of degrees of longitude, and the plate / -des-days and the plate - to units of minutes of longitude. Plates from 6 to R similarly correspond to hundreds of meters, ten points and units of degrees and minutes of latitude.

In addition, on the switch there is a handle L, which is resetting on two contacts Nord and Süd and handle M, also having two contacts Ost and Vest.

To set the desired position, it is enough to rearrange the sliders on their plates so that they touch the plate of the number that corresponds to the position of the vessel, and install the knobs M and

The contact drum of the insulating drum T, installed on the axis A, driven by a small motor M (electric or mechanical) by means of a gear.

The transmission is calculated so that the drum makes one revolution in four seconds, which approximately on average corresponds to the handing of the SOS signal,

On the surface of the drum T, there are two metal contact parts PI, РЗ. cut out according to FIG. 2, and these parts are electrically connected to the metal axis A.

On one forming the drum are located fourteen baskets from O to 9 and N L W O; with respect to the contact parts PI, P.:, these brushes are installed as shown in FIG. 2

The brushes are stationary, but the drum rotates in the direction indicated by the arrow; each brush from 0 d (9, for one revolution, the drum falls on such conductive parts, which correspond to Morse signs with the corresponding figure. Nunger, brush 4 meets four dots and one dash, brush 7 is two dashes and three dots n t. In the same way, H1, E, S, corresponding to the south (Sudu), meets three points. Brush W, corresponding to the West (Vesta), meets one point and two dashes.

IND callsign consists of a metal disk with protrusions corresponding to the Morse code of the ship's call sign. The interlayer between the projections is filled with an insulating substance; this disk is mounted on the axis at the end of the drum T, the brush 1 is in the JCHHH sonrikos with a disk circumference. It may happen that the length of the call signs in Morse code will be longer than the SOS signal; in this case, the device will have two callsigns, one of which will contain the first letters, the other will contain the last letters of the call, and the distributor, which will be discussed below, should have corresponding contacts that ensure the moral of the transfer of the call signs so the letters of the second followed non-badly for those of the first. Disk

for callsigns, it is separated from the drum T to facilitate the design of the apparatus, since the call signs are changed for each ship.

The SOS disk is arranged in the same manner as a disk with callsigns, but has projections corresponding to the signal S05. The brush So is in contact with the circumference of this disk; the SOS disk is installed on the ring and fastened;: e; 1 with such a device that it is easy to remove and replace it with “code disks that match the signals according to a predetermined} code. In this case, the device can be used not only in case of danger; the ship or aircraft will use these code disks together with the apparatus to transmit its state and position; Thus, for example, code discs may correspond to the following signals: “The weather is cloudy,, We go forward, etc.

The brush Q of the distributor BA is connected to the xpaiiOBbiM wheel R. The main axis A has a cam CA with zanlechiko. The latter pushes lever B, which turns the ratchet wheel R by one tooth at each turn of axis A; The CCL latch locks the specified wheel. This fixture is positioned so that at the end of each turn of the drum the wheel / and I1, chain Q is advanced one step. The brush Q moves along a row of sixteen L contacts or a collector with sixteen segments; The first three contacts are connected to the disk 505's bar, the next five contacts are connected respectively to each of the plates / to, the contact with the handle Ijo contacts /.jn with the plates from / to Ry and the contact L with handle M. Contacts L ,, and connected with a brush; I call sign.

The use of such a distributor has the advantage that the brush remains stationary during signal transmission. In this way contact is reliably secured. The movement of the brush from one contact to another occurs only at the end of each turn, when no signal is sent. For this, the length of the contact metal part P (Fig. 2) is made less than the sweep of the drum circle and the cam CA is wedged in such a way that the movement of the brush Q has a place at the end of the revolution when all the brushes and discs are on the insulating part.

The proposed radio transmit i sensor works as follows. Let, for example, the apparatus be stopped as shown in FIG. 1 position. When the INT breaker is closed, motor M starts up, pulls axis A in the direction indicated by the arrow, and cam C / 1 pushes lever B; The snorkel wheel is rotated one step: and the Q brush hits the contact L. Under these conditions, the SOS disk brush is connected to the contact, while the cam axis A is connected to the clamp L /. During the first rotation of the drum, the T signal is given once. At the end of this revolution, the cam: C A again i pushes lever B, brush Q switches to contact iyj, also connected to the brush bo, and during the second turn, the SOS signal is given a second time; at the end: with it, the brush Q switches to the contact Lg and the SOS signal l is the third time.

At the end of the third turn, brush Q | switches to contact b, connected to the plate, which slider is: in contact with the plate and then with | brush O drum T; as a result of | the fourth turn of the figure O passed; on clips L, L ,. At the end of the fourth turn, the brush switches to the contact ij connected to the plate /. ,, the slider which touches the plate N. connected to the brush 3; - thus, during the fifth turn, the number 3 is transmitted to the terminals / V of N.2.

In the same way, the transfer continues further, and at the end of each turn the brush Q moves to the next contact and the plates Ri along Rtj and the switch handles M and M are successively brought into the connection, on the one hand, with the distributor L / 1 and, on the other hand hand, digital plates and drum T with clamps N. Thus, the position signal is transmitted.

At the end of the fourteenth revolution, the 1st Q switches to the L contact, the brush / is connected to the / V clamp, the IND disk is connected to the axis and to the V clip; the sender and call sign will be transmitted to these clamps at the fifteenth, as well as to at sixteenth rpm.

Thus, a full turn of the brush Qi contributes to sixteen turns of the drum G and a full transfer of the right signal to the help of the sender's N, / Vg terminals.

Undoubtedly, if the SOS disk were replaced by a code disk, then instead of the SOS signal, a code signal would be transmitted.

If the ship's call sign were longer than the SOS signal, the radio transmitter would have two call signs, the first of which would correspond to the first letters of the call, and the second to the last. Then the distributor should have eighteen contacts, a ratchet wheel / - eighteen teeth and contacts L, and would be connected to the brush of the first call sign of the disk, and the contacts of Ljo and a brush of the second call sign.

The subject matter of the invention.
