Изобретение относитс к технике электросв зи и может использоватьс в аппаратуре телефонной св зи , эксплуатируемой в- услови х воздейстЫ на процесс осуществлени св зи акустических шумов с высоким уровнем интенсивности. The invention relates to telecommunication technology and can be used in telephone communication equipment operated under conditions of communication of acoustic noise with a high level of intensity.

Известно устройство телефонной св зи на объектах с высоким уровнем шумов, содержащее звукоприемники, первые электронные ключи и блокг включени , выходы которых подключены к управл ющим входам соответствующих первых электронных ключей ГП.A telephone communication device at high noise objects is known, comprising sound receivers, first electronic keys and a switch-on unit, the outputs of which are connected to the control inputs of the respective first electronic keys of the power supply unit.

Однако известное устройство имеет низкую устойчивость св зи.However, the known device has low coupling stability.

Цель изобретени - повышение устойчивости св зи.The purpose of the invention is to increase the stability of communication.

Цель достигаетс тем, что в устройство телефонной св зи на объектах с высоким уровнем шумов, содержащее звукоприемники, первые электронные ключи и блоки включени , выходы кото рых подключены к управл ющим входамThe goal is achieved by the fact that in a telephone communication device on objects with a high level of noise, containing sound receivers, the first electronic keys and switch-on units, the outputs of which are connected to control inputs

соответствующих первых электронных ключей, введены вторые электронные ключи, входы которых соединены с выходами соответствующих звукоприемников , а выходы вторых электронных ключей соединены с речевыми входами соответствующих блоков включени , при этом управл ющие входы вторых электронных ключей соединены с выходами соответствующих блоков вклю10 чени , а выходы вторых электронных ключей соединены с информационными входами соответствующих первых электронных ключей, выходы которых объединены .the corresponding first electronic keys, the second electronic keys are inputted, the inputs of which are connected to the outputs of the respective sound receivers, and the outputs of the second electronic keys are connected to the voice inputs of the respective switching units, while the control inputs of the second electronic keys are connected to the outputs of the corresponding blocks Electronic keys are connected to the information inputs of the corresponding first electronic keys, the outputs of which are combined.

Claims

A telephone communication device at JQ objects Q with a high level of noise contains sound receivers 1-3, first electronic keys -6, switch-on units 7-9, second electronic keys 10-12. The device works as follows. In the initial state, when the transmission is not conducted, the first electronic keys 4-6 are closed, and the second electronic keys are 10-12 open. At the moment of the beginning of the transmission, for example, by the first subscriber, the speech signal from the output of the sound receiver 1 through the open second electronic key 10 is fed to the input of the switching unit 7, which unlocks the first electronic key H transmitting the speech signal from its input to the output of the device. At the same time, the control signal from the output of the switch-on unit 7 is fed to the control inputs of the second electronic keys 11 and 12, locking these keys, and thereby disconnecting the sound receivers 2 and 3 until the end of the transmission by the first subscriber. Moreover, since sound receivers 2 and .3 are disconnected from the switching units 8 and 9; and the first electronic keys 5 and 6, respectively, forcing the speech to the second and / or third subscribers does not interrupt the transmission of the first subscriber, and therefore, does not violate the stability operation of the device by providing it with communication. The device works in the same way in cases when the transmission is carried out by the second or third subscriber. As the number of subscribers in one network increases, the number of described blocks increases accordingly, the links between which are similar to those described. Technical and economic effect of using this device is the possibility of increasing the number of subscribers working in one 94 network without introducing additional priority blocks and / or blocking, as well as due to the fact that s mechanical elements or electrical switching, the outputs of which have constant time sufficient to actuate the second electronic switches. Thus, the proposed device allows to improve the quality of communication, excluding possible failures. Claims of the telephone communication device on objects with high noise level, containing sound receivers, first electronic keys and switching units, the outputs of which are connected to the control inputs of the corresponding first electronic keys, characterized in that, in order to increase the stability of communication, the second electronic the keys whose inputs are connected to the outputs of the respective sound receivers, and the outputs of the second electronic keys are connected to the speech inputs of the respective switching units, while the control inputs second electronic switches connected to outputs of the respective inclusion blocks and outputs the second electronic switches are connected to the data inputs of the respective first electronic keys, whose outputs are combined.
