021018 B1

The present invention relates to communication systems in which signals propagate in free space, in particular to systems with geographically spaced radio receivers and radio transmitting devices using frequency diversity.

A known terrestrial mobile radio communication system of the ARCO 25 standard (patent application EP 1589676 A2, publ. 26.10.2005), containing geographically distributed receiving channels, the output of each of which is connected to a geographically distributed communication network, as well as a central router, the output of which is through the block processing and control is connected to the transmitting device, and subscriber receiving devices installed on mobile carriers configured to receive signals emitted by the transmitting antenna of the transmitting device, etc. and each receiving channel consists of a receiver connected in series with the receiving antenna, a data processing and transmission unit, and a router, the output of which is the output of this receiving channel.

A disadvantage of the known terrestrial mobile radio system is its limited scope. Like most other communication systems using the ARCO 25 standard, the well-known ground-based mobile radio communication system is focused on solving problems of power structures.

As a rule, these tasks are operational in nature and are accomplished with the help of mobile quick reaction forces (crews of patrol cars and on foot police or police units) dispersed over large territories. The indicated forces and means communicate with the dispatch center (call center) through a network of repeaters. Operational tasks can be solved autonomously by the response forces (within the framework of their delegated authority). In some cases, for example, during the implementation of the Interception operation, centralized management of the operation from the dispatch center is used. All subscriber radio stations with which the rapid reaction forces are equipped operate at the same frequencies. Communication with the dispatch center is carried out using error correction equipment and the selection of the best signal (Woet).

The peculiarity of this connection is that at the time of negotiations with the dispatch center of the crew of one of the patrol cars, the crews of other patrol cars cannot contact the dispatch center. When solving police (police) tasks, such a regime, as a rule, does not cause serious complications, since the crew of a patrol car can operate autonomously and independently make operational decisions.

In addition to solving the problems of power structures, there are other areas of application of mobile radio communication systems that differ in relatively low cost. One such area is the use of a mobile radio communication system in rail transport.

With this application, such a large area of coverage of the mobile radio communication system is not required as in solving problems of power structures. Accordingly, the use of repeaters is optional. However, higher demands are placed on the reliability of communications. In particular, the situation is unacceptable when, during negotiations with the dispatch center of one of the subscribers, other subscribers are deprived of the possibility of prompt (in real time) access to the dispatch center. Such situations can lead to a railway accident.

In this regard, in railway transport, subscriber stations operate at different frequencies, and the receiver installed in the dispatch center is multi-channel.

The closest analogue of the claimed invention is a multi-channel radio communication system according to the applicant’s patent for utility model KI 82970 I1, published May 10, 2009, containing a controller, several radio receivers, a receiving antenna with an antenna-matching device, the outputs of which are connected to the inputs of the radio receivers, the control inputs of each of which are connected to the corresponding control outputs of the controller, and the information and service outputs of radio receivers - with the corresponding inputs the controller, a radio transmitting device with a transmitting antenna, connected to the controller, a multi-channel negotiation recording unit, to the inputs of which the corresponding outputs of the controller are connected, a remote control unit containing sound and light indication blocks, to the input of which is connected the information output of the controller, the corresponding input of which is connected to remote control output

This multi-channel radio communication system has a fairly wide scope, in particular, it can be used in rail transport. This is confirmed by the prolonged use of the Altavia-155 multichannel stationary radio station, made in accordance with the closest analogue (11ir: // \ y \ y \ u.e1ek1gorpog1.gi / a11a \ aa155). However, this same long-term use showed that the operator of the remote control is overloaded with solving the tasks of coordinating the actions of users of portable and portable radio stations that are directly part of a multi-channel radio communication system. Such excessive loading can cause operator errors (human factor), the consequences of which are not predictable.

The claimed invention ensures the preservation of the advantages of the closest analogue while solving the problem of significantly reducing the load on the operator of the remote control.

The technical result achieved using the proposed solution is to provide additional opportunities for temporary control of the system from another, more simple remote control.

The technical result is achieved by the fact that in a multi-channel radio communication system containing a controller, several radio receivers, a receiving antenna with an antenna matching device, the outputs of which are connected to the inputs of the radio receivers, the control inputs of each of which are connected to the corresponding control outputs of the controller, and information and service the outputs of radio receivers - with the corresponding inputs of the controller, a radio transmitter with a transmitting antenna connected to the controller, many an anal negotiation recording unit, to the inputs of which the corresponding controller outputs are connected, a first remote control containing the first sound and light indication blocks, to the input of which a controller information output is connected, the corresponding input of which is connected to the output of the first remote control, according to the proposal, a selection block is introduced channels and a second remote control that includes second blocks of sound and light indication, the output of the channel selection block s is connected to the control input of the second remote control, the output of which is connected to the corresponding input of the controller, the information output of which is connected to the information input of the second remote control, and the control output is connected to the first input of the channel selection unit, the second input of which is connected to the control output of the first remote remote control.

The technical result is also achieved by the following special cases of nodes of the system.

The first remote control can be configured to connect to a computer for programming the parameters of the controller, the first remote control, channel selector, as well as radio transmitting and receiving devices.

Radio transmitting and receiving devices can be configured to function in the ARCO 25 standard.

The channel selection unit and the second remote control can be structurally implemented in a common housing.

The transmitting and receiving antennas are preferably spaced apart from each other, eliminating the possibility of blocking radio receivers by the signal emitted by the radio transmitting device.

The radio transmitting device can be configured to operate in both digital and analog modes, while digital encryption of voice messages and data packets is possible.

A multi-channel radio communication system comprises a controller 4, several radio receivers

3, a receiving antenna 2 with an antenna matching device 1, the outputs of which are connected to the inputs of the radio receivers 3, the control inputs of each of which are connected to the corresponding control outputs of the controller 4, and the information and service outputs of the radio receivers 3 - with the corresponding inputs of the controller 4. B the composition of the multi-channel radio communication system also includes a radio transmitting device 10 with a transmitting antenna 11 connected to the controller

4. The multi-channel radio communication system also includes a multi-channel conversation recording unit 12, the inputs of which are connected to the corresponding outputs of the controller 4. In addition, the multi-channel radio communication system includes a first remote control 5, comprising sound and light indication units 9 and an additional second remote 6 remote control containing the second blocks 8 of sound and light indication. The inputs of the first remote control 5 and the second remote control 6 are connected to each other and connected to the information output of the controller 4, the corresponding inputs of which are connected to the outputs of the first remote control 5 and the second remote control 6. Part

- 2 021018 multichannel radio communication system also includes a channel selection unit 7, the output of which is connected to the control input of the second remote control 6, and the first and second inputs, respectively, with the control output of the controller 4 and with the control output of the first remote control 5.

A multi-channel radio communication system may comprise several additional second remote controls 6, however, to simplify the presentation, the present invention considers only one second second remote control 6.

Controller 4 fully corresponds to the router and the geographically distributed communication network used in the closest analogue circuit. Since the objectives of this utility model do not include ensuring interconnection of blocks at large distances, as well as for ease of presentation, controller 4 was used, combining the functions of a router and a geographically distributed communication network (although the real scheme of hardware implementation of this utility model uses a geographically distributed communication network).

All the blocks that make up the proposed system, except for the channel selection block 7 and the second remote control 6, repeat the corresponding blocks of the closest analogue, and their hardware implementations are part of the Altavia-155 multi-channel stationary radio station mentioned above (PIR: // \ y \ y \ u.e1ek1horpBog1. gi / a11au1a155).

Moreover, only the functions of the first remote control 5 remote control are somewhat complicated, since it is also used to control the operation of the channel selection unit 7.

The second remote control 6 is a simplification of the first remote control 5, so the possibility of its hardware implementation is beyond doubt.

Block 7 channel selection is in its functions the simplest decoder that controls the key circuit. When programming, the first remote control 5 puts in the block 7 channel selection channel numbers for which the key circuit must be open. Block 7 channel selection remembers these numbers and does not pass into the second remote control 6 remote control channel signals with other numbers. Similar blocks are widely known.

The hardware implementation of the channel selection unit 7 and the additional remote control 6 is made in a single housing and is named by the applicant as a device for remote channel switching of the VHF radio communication system. At the applicant enterprise, a single production of such devices has been mastered. They are supposed to be included in the modification of the aforementioned multichannel stationary radio station Altavia-155. This modification was called Altavia-155M02.

Therefore, the possibility of practical implementation of the proposed utility model is not in doubt.

The proposed invention works as follows.

Antenna matching device 1, the input of which is connected to the receiving antenna 2, and the outputs to the inputs of the respective radio receiving devices 3, ensure that all radio receiving devices 3 work through a common receiving antenna 2. The radio receiving devices 3 receive their signals independently of each other (each on its own frequency), decode them and send the received speech signals and decoded data to the corresponding information inputs of the controller 4. The presence of one receiving antenna 2 simplifies the placement of the antenna economy on the object .

Radio receivers 3 can be analog with frequency diversity or digital, configured to operate in the ARCO 25 standard.

In the controller 4, the processing of decoded data and the summation of speech signals occur. If necessary, at the command of the operator from the first remote control 5, the controller 4 can turn off some radio receivers 3 (reception channels).

Such a shutdown corresponds to the fact that a number of wearable or portable transmitting devices, the signals of which were to be received by these radio receivers 3, are temporarily withdrawn from the multichannel radio communication system (for example, transferred for temporary use to another organization).

From the output of the controller 4, the total speech signal is sent to the first remote control 5 and the second remote control 6. Information about the channel number in this case enters the block 7 channel selection.

The operation of the channel selection unit 7 is determined by the last program of work established in the multi-channel radio communication system. To install such a program of work, it is enough to connect the first remote control 5 to the computer (it is not shown in the figure) on which the corresponding software is installed. After that, the operator of the first remote control 5 of the remote control gets the opportunity to configure the blocks of a multi-channel radio communication system, adjust their parameters and update the firmware. In particular, the program of the block 7 channel selection is updated.

The channel selection unit 7 acts on the second remote control unit 6, suppressing the transmission to the second sound and light indication units 8, which are part of the second remote control unit 6 3 021018, all signals of the controller 4, except for signals with channel numbers set for the unit 7 channel selection when programming it. If, for example, when programming on the channel selection block 7, not a single channel number was entered, then the second sound and light indication blocks 8 will suppress all input influences. No signals will be received, and the second remote control 6 will be excluded from the number operating in a multi-channel radio communication system. The operation of a multi-channel radio communication system will be fully consistent with the known work of the closest analogue. In this mode, the second remote control 6 can simply be turned off.

Suppose now that the operator of the first remote control 5 is to temporarily leave his workplace (for example, during a lunch break). Since the territorial location of the multi-channel radio communication system is tens of square kilometers, replacing the operator with an employee who is qualified to work with the first remote control 5 is a rather difficult task. Therefore, before leaving the workplace, the operator of the first remote control 5 can program the channel selection unit 7 so that the transmission of each channel will not be suppressed. Then the second remote control 6 will for some time perform all the functions of the first remote control 5 for receiving messages, and the employee working with this second remote control 6 will be able to temporarily replace the absent operator of the first remote control 5. At the same time, the second remote control 6 is much simpler, it does not have complex devices, such as a touch screen, and the tasks that it must perform are also not too complicated. For example, from the second remote control 6, it is not necessary to disconnect the radio receiver 3. This means that a temporary substitution of the operator of the first remote control 5 can be carried out by an employee of substantially lower qualification, which is not difficult to find. When the second remote control 6 is operating in this mode, the channel selection unit 7 may be a conventional communication line.

After his return, the operator of the first remote control 5 must again reprogram the channel selection unit 7 to disconnect the second remote control 6 from the controller 4 (in the simplest case, just turn off the additional remote control 6) and continue to receive and transmit messages for Wearable and transportable radio stations that are part of a multi-channel radio communication system. In this case, the operator will have to use the first blocks 9 of sound and light indication, which are part of the first remote control 5 of the remote control.

Suppose now that a certain group of users of wearable or transportable radio stations is engaged in a certain common, joint business, for example, the search for some lost cargo that the receiver urgently needed. These users, who have portable or portable radio stations at their disposal and work together, need a special guide. To the operator of the first remote control 5 of the remote control, these collaborative employees are particularly difficult to manage their work. Therefore, for such an example, it is possible to justify the transfer of several channels for control from the second remote control 6 of the remote control. Such transmitted channels in a special way stand out in the first blocks 9 of sound and light indication, which are part of the first remote control 5 of the remote control (for example, are reduced to a special auxiliary window).

Thus, on the first remote control 5 using the first blocks 9 of sound and light indication displays the status of each of the radio devices 3, and on the second remote control 6 using the second blocks 8 of sound and light indication displays the status of the radio devices 3 in accordance with the program of the block 7 channel selection.

The first blocks 9 of sound and light indication and the second blocks 8 of sound and light indication also reflect signals of additional service information about the state of a territorially remote radio transmitting device 10, emitting a sufficiently powerful signal using transmit antenna 11. The assignment of the radio transmitting device 10 to a sufficiently large distance from the rack, which houses the radio receiving device 3, can significantly reduce the likelihood of clogging of the receiving channels with a powerful signal of the radio transmitting device 10, thereby further improving the reliability of the entire multi-channel radio communication system.

The radio transmitting device 10 can operate in both digital and analog modes. Moreover, in digital mode, using the open digital communication standard ARCO 25, encryption of voice messages and data packets is possible, which also increases the reliability of the multichannel radio communication system under consideration.

When you press the headset button connected to the first remote control 5 or the second remote control 6, the speech signal from the headset microphone is sent to the controller 4 and then (for example, via a duplex communication channel) is transmitted to the radio transmitting device 10. Through the same communication channel from the first remote control 5 or from the second

- 4 021018 of the remote control 6, a corresponding control command is sent, having received which the radio transmitting device 10 switches to a predetermined channel and enters the transmission mode. When you release the headset button (or in other situations determined by the algorithm of the system), a command to turn it off is sent to the radio transmitter 10.

An important property of the multichannel radio communication system under consideration is that it operates in duplex mode, i.e. the radio receiving devices 3 can operate even during operation of the radio transmitting device 10. Moreover, the radio transmitting device 10 does not clog them with its signal.

Another important distinctive feature of the considered multi-channel radio communication system is that all signals from the speech outputs of the radio receivers 3, as well as the signal supplied to the speech input of the radio transmitting device 10, are sent through the controller 4 to the corresponding inputs of the multi-channel negotiation recording unit 12. The source of the signal supplied to the speech input of the radio transmitting device 10 is also indicated. Such a source can be either a first remote control 5 or a second remote control 6. This allows you to carry out objective continuous monitoring of the proposed multichannel radio communication system and the operator of the first remote control 5, as well as a substitute employee using the second remote control 6. It also improves the overall reliability of the multi-channel radio system.

It should be noted that the hardware implementation of the second remote control 6 developed and launched into a single unit at the applicant's enterprise includes a pedal, a desktop microphone and an external speaker in the housing, a special adapter for connecting to the first remote control 5, which is part of the multi-channel radio communication system Altavia-155. This special adapter is, in terms of the present invention, a channel selection unit 7 structurally located in one housing with an additional remote control 6.

The choice of the working channel is carried out by pressing one of the special buttons with the subsequent illumination of the green LED opposite this button.

Under each row of buttons is a removable retractable transparent bar for laying under it a strip of paper for the call sign.

That is, it is not difficult for the operator of the second remote control 6 to carry out his work in coordinating the actions of users of portable and portable radio stations that are part of the proposed multi-channel radio communication system.

The introduction of the second remote control 6 into the multichannel radio communication system really unloads the operator of the first remote control 5 and, therefore, reduces the likelihood of errors in its actions, i.e. provides increased reliability of the system, taking into account the human factor.

Thus, the proposed technical solution allows you to create reliable radio communication systems in railway transport.
