Description

The utility model relates to radio communications, in particular to switching equipment placed on mobile equipment, primarily on a tracked chassis, with internal (inside the mobile equipment) and external (outside the mobile equipment) communication equipment with laryngophone-telephone headsets of helmet telephones. The interface device is intended to provide the crew commander with internal telephone communication with crew members and external radio communication with subscribers both through standard on-board radio stations (hereinafter referred to as on-board radio stations) and an additionally installed portable radio station.

The interface device can be used to provide communication between crews of mobile vehicles with increased cross-country capability and foot escort groups (hereinafter referred to as the escort group) during rescue and search operations in hard-to-reach areas.

The communication system of modern mobile tracked equipment provides:

internal two-way telephone communication between crew members;

external communication via any of the two on-board radio stations;

listening to the call signal from the on-board radio station;

sending calls to external subscribers via the on-board radio station.

A special feature of the organization of communications in mobile tracked vehicles is the use of helmet-type telephones by crew members, which not only protect the hearing organs from powerful acoustic noise, but also, due to the telephones (headphones) and laryngophones located in them, ensure operation of radio and telephone communication equipment of internal communication devices.

Equipping the crew commander and support groups with portable radio stations to coordinate their joint actions allows for the organization of a separate communication channel via this radio station. In this case, the electric circuit of the portable radio station must be switched into the electric circuit of the mobile object and allow for communication using the commander's laryngophone-telephone headset available on board the object in conditions of increased acoustic noise inside the mobile equipment.

A device known as "Tank intercom with separate telephone switching" [USSR Patent No. 112112 of 22.07.1957] includes a device for coupling communications equipment, made in the form of an intercom (hereinafter referred to as PU) with a chest switch for the crew commander, into which a plug connector for connection to a helmet telephone, a two-position switch - transmission/reception of information via two on-board radio stations, as well as a button for transmitting information via internal telephone communication, a block for switching on the chest switch in the PU are mounted. The coupling device allows the crew commander to switch from radio communication via one of the two radio stations to internal telephone communication and vice versa.

This device is part of the communication equipment, which includes: a control panel located on a mobile object with connecting cables; a plug connector for connecting a chest switch; a chest switch of the crew commander; a switching relay; a panel for connecting power wires; switching wires for connecting helmet telephones for crew members; laryngophones of the same helmet telephones. For the reception and transmission of information by the crew commander via external or internal communication, a subscriber number switch is located on the control panel.

The disadvantage of the analogue is the duplication of the functions of switching communication channels on the chest switch of the crew commander and the switch on the control panel, which complicates the work of the commander.

A device for interfacing communication equipment for mobile armored vehicles is known [A.V. Bezlyudko, V.V. Usovich, R.I. Sharipov et al. The device of the T-72B tank. // Study guide. / Publishing house of BNTU Minsk. 2002. 737 p.], adopted as a prototype, which includes a control unit, external communication equipment and internal communication equipment, as well as chest switches and helmet telephones for crew members.

The communication channel is switched from external to internal by the crew commander using the communication interface device, which is the PU with a chest switch and the crew commander's helmet. The communication channels are switched using a four-position rotary switch on the commander's control panel, which is part of the PU: communication via one of the onboard radio stations, internal communication, and communication off. When the communication is on, the crew commander uses a laryngophone-telephone headset built into the helmet to receive or transmit voice information via the communication line whose channel is selected using the rotary switch on the control panel.

The mode of receiving or transmitting information is carried out using the push-to-talk button on the chest switch, which has two positions: call - "CALL" and transmission - "PRD". In the neutral position of the push-to-talk button, the commander receives voice information from subscribers externally via onboard radio stations or via internal telephone communication via the helmet earphones. To communicate via one of the onboard radio stations, the rotary switch is set to the appropriate position, and the "CALL" push-to-talk button on the chest switch is pressed to send an audio signal to the subscriber and, after the subscriber responds, by moving the push-to-talk button to the "PRD" position, voice information is transmitted to the subscriber. When the push-to-talk button is released, voice information is received.

In the position of the rotary switch on the control panel "VS" - internal communication, the commander carries out two-way communication with the crew members by switching the positions of the push-to-talk switch on the chest switch.

Thus, the device for coupling mobile communications equipment provides separate communication via two on-board radio stations with external subscribers and internal telephone communication with crew members.

A common drawback of the analogue and the prototype is the impossibility of the simultaneous use by the crew commander of the communication channels of the mobile equipment and an additionally organized separate channel via a portable radio station for communication with the escort group, due to the fact that this radio station does not have electrical circuits for interfacing with the laryngophone-telephone headset of the commander's helmet telephone, without which it is impossible to use it (due to the high levels of acoustic noise inside the mobile equipment).

The objective of the utility model is to provide the ability for the commander of a mobile vehicle crew to jointly use internal telephone and external radio communications using onboard radio stations, as well as an additional channel via a portable radio station for communication with the support group when using one laryngophone-telephone headset of the commander's helmet telephone in conditions of high acoustic noise levels.

The technical result is achieved in that the device for coupling the means of communication, which is a control unit with a chest switch of the crew commander, equipped with a push-to-talk key for switching the operating mode "call/transmit" of speech information, and the commander's helmet telephone, characterized in that the device includes a switching module, functionally and electrically connected to the communication equipment of the mobile equipment and consisting of a switching unit, a connecting cable and a connector for connecting to a portable radio station, wherein the switching unit is equipped with two rectangular electrical connectors located on opposite ends of the unit, to one of which, made in the form of a rectangular connecting electrical socket, a rectangular connecting electrical connector from the crew commander's helmet telephone is connected, and to the other, made in the form of a rectangular connecting electrical plug, the chest switch is connected, and on the housing of the switching unit there is a button for connecting the portable radio station to the electrical circuit for transmitting speech information using the laryngophones of the crew commander's helmet telephone, and the connector for connecting to the radio station is made in the form of a rectangular electrical connector for connection to an electrical circuit for receiving/transmitting radio communication information with the support group, while the transmission of voice information via a portable radio station is carried out by the commander of the mobile equipment crew through the laryngophone of the helmet-type telephone by pressing the normally open button located on the housing of the switching unit, and reception - with the button open through the headphones of the helmet-type telephone.

Thus, the switching module is connected in the gap between the chest switch and the crew commander's helmet telephone and is part of the device for interfacing mobile communications equipment.

An electrical connector (electrical plug) is understood [GOST 21962-76. Electrical connectors. Terms and definitions] as an electromechanical device intended for mechanical connection and manual disconnection of electrical circuits (wires, cables, units and blocks) in various types of electrical and radio equipment.

The switching unit 1 of the communication means interface device is a housing having electrical terminals in the form of a socket connector 2 and a fork connector 3 for connection to connectors 4 of the crew commander's helmet telephone 23 and 6 of the chest switch 7, respectively. On the housing of the switching unit 1 there is a button 9 for switching the information reception/transmission mode, as well as a cable 11 with an electrical connector with a rectangular fork connector 10 for connection to a portable radio station 24. In this case, the connecting connectors 2, 3 are made rectangular, connector 2 is similar to connector 6, and connector 3 is similar to connector 4. The switching module is connected to the portable radio station via fork connector 10, which is part of the module, which is connected to the radio station 24 (Fig. 6) via its socket connector, intended for connecting additional devices (control panel, data input cable, cable with USB port - not shown in Figs. 1-6).

When connecting the switching module to the interface device through connecting connectors 2 and 4 of switching unit 1, the electrical circuit (see Fig. 1) from the speaker of the portable radio station is connected to the electrical circuit of the headphones of the helmet-type telephone, and the microphone of this radio station is connected through the normally open button 9 to the information transmission line of the laryngophones of the helmet-type telephone of the communication network of the commander of the mobile equipment.

In this case, the housings of the switching unit 1 and the connector 10 for connecting to the portable radio station are made up of two elements each (see Fig. 2, 3) and are made of a plastic material, for example, by 3D printing from PETG plastic, and are also dust- and moisture-proofed with a layer of hot-melt adhesive between their component parts.

For the output of electrical contacts in the housing 1 of the switching unit, through holes 19 are made according to the number and diameter of electrical contacts of the 3.3 mm contact plug and the 3.3 mm contact socket for the Universal MATE-N-LOK connectors. Holes 17 and 18 of the housing 1 of the device (see Fig. 2) are used for mounting the switching button 9 and the connecting cable 11 to the portable radio station (see Fig. 1), respectively.

The contacts are mounted in the housing of the device 1 by melting through the holes 19 (see Fig. 2, 3), and then secured and sealed with a layer of hot-melt adhesive. To output the electrical contacts in the connector 10 through the drilled holes 21 (see Fig. 4), electrical spring-loaded contacts (pogopins) are mounted by melting into the plastic housing of the connector 10.

The connection of two composite plastic elements of the housing 1 of the switching unit is carried out with two screws with nuts 16 through through holes 15 (see Figs. 2, 3, 5). The fastening of two composite plastic elements of the connector 10 for connecting the switching unit to the radio station 24 is carried out with self-tapping screws (not shown in Figs. 1-6) through through holes 22 located (made) in the corners of the connector 10 (see Fig. 4). The fastening of the connector 10 for connecting the switching module to the side panel of the portable radio station 24 (Fig. 6) is carried out through through hole 20 (see Fig. 4) with a captive bolt 14 (Fig. 5) with a thread corresponding to the hole for connecting additional devices to it: the control panel of the radio station 24, a data input cable, a cable with a USB port.

The button 9 for switching the reception/transmission mode of the portable radio station is placed on the outer side of the housing 1 and is connected to the electrical network in the information transmission line 13. For example, a normally open push-to-talk button can be used as the switching button 9, for example, OFF-(ON) PBS33B (1A 250VAC).

The articulated electrical connectors 3 and 6, as well as connectors 2 and 4, chest switch 7, the housing of the switching unit 1 of the switching module form a single unit (see Fig. 6), which is placed in the palm of the crew commander and allows him to communicate with subscribers via external and internal communications by pressing the push-to-talk button 25 of the chest switch 7 or with the support group via a portable radio station by pressing the button 9.

The interface device operates as follows. When connecting the switching unit 1 of the switching module to the connectors 4, 6 connecting the helmet telephone 23 with the chest switch 7 of the crew commander, the button 9 is open (Fig. 1). The crew commander selects the internal or external communication channel by setting the rotary switch on the control panel (not shown in Figs. 1 - 6) to the corresponding selected position. Then the crew commander sends an audio signal to an internal or external subscriber by moving the push-to-talk switch 25 (see Fig. 6) of the chest switch 7 to the "CALL" position until the subscriber answers. After the called subscriber answers, the commander transmits the information to the crew members or external subscribers by moving the push-to-talk switch 25 (Fig. 6) of the chest switch 7 to the "PRD" position. In the neutral position of the push-to-talk switch 25, the commander receives information from the called subscriber.

If it is necessary to transmit information to an external subscriber via a portable radio station, the crew commander presses button 9 and, holding it, transmits voice information. When it is released, information is received via the crew commander's helmet earphones (not shown in Fig. 1-6) 23 via internal or external communication lines, including via the communication channel with the escort group.

The switching module of the interface device can be connected and used, in addition to the crew commander, by any member of the mobile equipment for external communication using a portable radio station.
